Résumé :
The piping design should be considered by way of the network system in order to supply water for reliable fire extinguishing. However, the pipe scheduling method in line by the National Fire Safety Code is typically applied. When the modeling analysis method of fluid behavior is utilized based on the piping network theory, the fire-extinguishing water can be supplied more stably in a large-scale plant. Because a piping network consists of a large number of node points as well as consumes a lot of time and effort, it is recommended to use the commercial analysis program according to international standards. In this study, we used a piping network analysis program, sisHYD, which can model the actual piping according to the coordinates and analyze the fluid behavior inside the piping. As a result of the piping network analysis, it was possible to reduce the diameter of piping while ensuring the supply stability of firefighting water compared to the pipe scheduling method. Consequently, the value engineering effect of a construction project can be enhanced by reducing the wasted budget and inefficient factors.

Résumé :
One of the current topics in the seismic design of piping systems is the overall reliability of them in earthquake events. Actual piping systems are generally supported by independent structures such as vessels and steel structures. So, it is very important to clarify the behavior of actual piping systems during the seismic events. For this purpose, the analytical method of multiple excitation problems is a preferable approach to not only evaluate the actual behavior of the piping systems, but also improve the reliability of piping systems. To clarify the dynamic characteristics of the piping systems and to assess the computational methods in the linear system subjected to multiple support excitations, an experimental study using a realistic large-scale piping model has been conducted. The equations for the multiple excitation problem have been validated and the adequacy of the multiple response spectra method has been confirmed by the comparison of the test results with the analytical one. This paper reports the results focusing on the analytical methods of the multiple support piping system. It is noted that the multiple response spectrum method is efficient for the multiple excitation problems.

Résumé :
Design of piping system requires a systematic consideration of various factors as addressed by the codes and standards. This research paper aims to provide a method for flexibility analysis of a selected area of process piping at an industrial plant. Analysis is done for the purpose of accommodating a spare heat exchanger in the process layout. The analysis follows a systematic procedure, with preparation of a tentative model of the system on CAESAR II software followed by insertion of different pipe supports. The selection and location of these supports is based on the results obtained from displacement, stress, reaction and equipment nozzle analysis of the piping system. The design is in accordance with ASME B31.3, which is the standard code for process piping. The proposed method can be adapted for piping configuration of any industrial plant. With the provision of a systematic procedure, the method ensures time saving and efficient flexibility analysis of any piping system.

This article proposes a new pressure piping according to the current high-voltage device development tendency and the future requirement. This new type of pressure pipe can be simplified for pipe casing model. Firstly we establish single, double and multilayer pressure piping model. We push out the multilayer pressure pipe stress formula according to stress situation of the analysis of the knowledge of mechanics of each model. We get this pressure piping withstand by the most intrinsic pressure enhance obviously under each layer within the radius of the cylinder reach the initial limitation of materials and other parameters of model are same through the comparison of the theoretical formula calculation with other general. Pressure pipeline calculated value. The multi-layer pressure piping system's circum radius are smaller than other piping with other pressure piping withstand the same most intrinsic pressure and the most interior radius are the same situation.

Résumé :
During plant operation, high temperature and high pressure water and steam are flowing at high velocity inside these piping systems. In pipes of power plants, local wall thinning may result from erosion/corrosion(E/C). Therefore, it is important to evaluate the nondestructive characteristics for corroded pipes to maintain the integrity of the secondary piping systems. In this study, the pressure vessel piping with corrosion used during long terms were investigated from the timefrequency analysis method. The damage of piping could be evaluated by ultrasonic parameters such as center frequency and echo waveform. Based on NDE analysis by time-frequency analysis method, it should also be possible to evaluate from various damages and defects in piping members.

Résumé :
This paper is a basic study on the vibrational characteristics of an LMFBR piping system containing liquid sodium under one-dimensional seismic excitation. Using Z-shaped piping, we formulate coupled equations for the pipe’s bending vibration and pressure wave, and transform them into two-degree-of-freedom vibration equations for the first modes of the piping vibration and pressure wave. A numerical study using the vibration model shows that: 1) the coupling effect appears between piping acceleration and liquid pressure for a piping configuration having a natural frequency ratio ν = about 0.5 to 2.0; 2) the magnitude of seismically induced pressure reaches 0.7 kPa to 1 kPa per gal; and 3) the dead-mass model of liquid gives a nonconservative response depending on the pipe’s geometrical configuration, compared to that from the pressure-wave-piping-interaction model.

Résumé :
Kedung Uling earthfill dam is located between Eromoko and Wuryantoro district, Wonogiri Regency, Central Java, Indonesia. Water leaked from the dam was found and could decrease volume of dam. The objectives of this study are to identify piping and to recommend for solving piping problem. In order to determine the piping direction and litological pattern, investigation of 10 boreholes with various depth has been carried out. This investigation aim to determine characteristics of soil and rock by analyzing 45 cm of thickness of undisturbed samples and to perform permeability test. Permeability test have been conducted by falling head method with 3 different depths. Leaking at the dam was analyzed by Slide 6.0 software. The results indicated that litology of dam have been identified as claystone, sand and tuff. The piping passed under the eastern abutment of the dam is the accumulation of groundwater in the aquifers formed by 8-10 meters thick layer of sand. The total debit of piping is 17,774 cm3/sec. The Factor of safety of piping is under the minimum of standard namely 3,6. Grouting is one of alternative method to minimize the piping. Grouting was simulated to reduce permeability value and increase soil strength. By grouting, the total debit of piping was reduced to 3.314 cm3/sec.

Résumé :
The ratcheting strains of the straight and elbow piping under two kinds of loads—pressurized piping under symmetric cyclic bending and pulsating cyclic pressure were analyzed based on Chaboche constitutive model. The locations of the maximum ratcheting strain were determined. The ratcheting boundaries of the two piping structures under two kinds of loads were compared and calculated by the C-TDF method. For the pressurized piping under symmetric cyclic bending, the allowable bending load increases from E90S to E90L under the same pressure. In the higher cyclic pressure range, the allowable pressure have little difference under the same bending load which indicates that the bend moment have a bit effects on the ratcheting boundary in the higher cyclic pressure range.

Résumé :
Classified as critically endangered since 1994, the Trinidad Piping guan (Pipile pipile) is an endemic species estimated to number less than 200 individuals. Known to locals of Trinidad as the ‘Pawi’ this bird has been the subject of substantial hunting pressures and much of the species habitat has been destroyed through deforestation. Although officially protected since 1958, occasional recreational hunting of this elusive species still occurs. Due to difficulties locating and capturing the species, no genetic research has previously been performed using samples obtained from Trinidad. All previous research studies have been conducted using biological materials obtained from captive birds outside Trinidad and island data has never been obtained or compared. The genetic diversity of the remaining population was therefore examined through the investigation of mitochondrial haplotypes, pairwise comparison and SNP analysis. With the intention of assisting the protection of this endangered species by the location of remaining areas of habitation, methods of genetic identification were established for the Trinidad Piping guan utilising non-invasive feather samples. Species specific primers were created in the regions of the ND2 and cyt b genes of the mitochondrial genome to identify Pipile pipile. Species detection was further verified with the use of PCR-RFLP of the same gene regions digested with BsaXI, EcoRV and BsrDI. This combined approach allowed the separation of closely related taxa based on single inter-species SNPs. Confirmation of species identification was subsequently performed through the use of forensically informative nucleotide sequencing. The established methodologies were used in the current study to correct the classification of a UK breeding population of Piping guans thought to be Pipile pipile and to identify Trinidad field samples. These detection methods have implications for ecological studies through the location of populations from trace evidence collected in the field. In addition this method could be used to assist Trinidadian police forces in the identification of bushmeats or simply act as a deterrent to hunters. The sequence data obtained in the present study were also used to re-assess the phylogeny of Piping guans. As genetic sequence from a true island bird was previously unstudied, differences between phylogenies created using non-island and island bird data sets were examined. Combined analysis was performed on 1884bp of the ND2 and cyt b genes and placement of Trinidad Piping guan was found to differ from that which has been previously published.

Résumé :
A piping system generally consists of primary system, large pipes, and secondary system, small pipes [1]. The primary system can be analysed separately without considering the secondary system. However, the opposite is not true because the primary system affects the movement of the secondary system. The aim of this study is to investigate the possibility of analysing the small pipes separately, which is called for sub-modelling, and then if the sub-modelling is possible, generate and validate a method which makes this sub-modelling possible. The response spectrum method [2] is used for analysing the structure. A ground acceleration spectra in three directions is applied at the primary structure, a new floor response spectra is then generated with the results from the analysis of the primary structure [3]. The calculated floor response spectra is applied at the secondary structure. The results from this analysis is compared to the results from applying the ground acceleration at the total structure. Two different ground accelerations are applied on two different models. A separation would be allowed if the results of the secondary structure are more than 90% of the results of the whole structure in all parts of the secondary structure in all studied cases. The results after separation reach more than 100% of the results from the analysis of the whole structure, called for conservative results, in three cases but not all the cases. The separation will be allowed in those three cases where the results reach 90% of the results taken from the whole structure, but not in that case where results does not reach 90%.
Vanligtvis består ett rörsystem av ett primärsystem, stora rör, och ett sekundärsystem, klena rör. Det primära systemet kan analyseras separat utan att ta hänsyn till det sekundära systemet. Men det är inte möjligt att analysera det sekundära systemet utan att ta hänsyn till det primära, eftersom det primära systemet påverkar rörelsen av det sekundära systemet. Syftet med denna studie är att undersöka möjligheten att analysera de små rören separat, och sedan om denna separation är möjligt, skapa och validera en metod som gör denna separation möjligt. Metoden responsspektrum används för att analysera strukturen. En grundacceleration spektra i tre riktningar tillämpas på den primära strukturen, sedan genereras ett nytt spektra med resultaten från analysen av den primära strukturen. Den beräknade responsspektra appliceras sedan på den sekundära strukturen. Resultaten från denna analys jämförs med resultaten från applicering av grundaccelerationen på den totala strukturen, när den primära och sekundära strukturen sitter ihop. Två olika grundaccelerationer appliceras på två olika modeller. Separationen kommer att tillåtas om resultaten av den sekundära strukturen är mer än 90% av resultaten från hela strukturen i alla delar av den sekundära strukturen i samtliga studerade fall. Resultaten efter separationen uppnår till mer än 100% av resultaten från analysen av hela strukturen, kallad för konservativa resultat, i tre fall men inte alla de studerade fallen. Separationen kommer att tillåtas i de tre fallen där resultaten når 90% av resultaten som tagits från hela strukturen, men inte i det fallet där resultaten inte når 90%.

Résumé :
Piping systems are among the most important systems in modern industrial facilities, which are also highly affected by events like earthquakes, hurricanes, flood, etc. Like nerves in our body they nurture the industrial plants and hence require protection from these events. For dynamic and specially seismic loading there is no universally accepted design code, hence research is still underway in this area. The response of a system excited by ground motions has two components: (1) pseudo-static which is due to the ground displacement at support points and (2) dynamic which is due to the vibrational excitation. The current methods of estimating that response are typically based on the assumption of a uniform ground motion. Some authors have recently attempted to modify the methods for the spatial variations of ground motion. In this work a different method is presented which also considers the non-uniformity in support excitations. The treatment is based on the random vibration principles and can develop the pseudo-static time history of the system and also the maximum dynamic response at each degree of freedom. For a typical piping system, the correlated ground acceleration and displacement time series are developed at the excited support points. The time series are used to develop the pseudo-static component, and also for the dynamic component by means of a classical step-by-step integration method. Dynamic responses are also developed by the stochastic method and some current methods and are compared, in each case, with the results from the integration method. It is verified that the stochastic results are comparable with the current method results. Comparing the results in case of a uniform and a non-uniform ground motion, it is shown that the cross correlation of support inputs does affect the components of the response significantly and the effect is not predictable. It is also shown that neglecting the non-uniformity in ground motions can lead to an underestimation of results, in some cases, while in some other cases to an overestimation.

Os resultados apresentados referem-se à investigação dos mecanismos de interação entre dois sistemas vitais às usinas nucleares, ou seja: os sistemas Principal (SP) e o Secundário (SS). Estes mecanismos são avaliados por meio de sua influência nos espectros de resposta, em pontos da estrutura passíveis da existência de suportes das linhas de tubulação - SS. São usados dois tipos diferentes de análises para a geração dos espectros de resposta: a primeira não considera a interação dos sistemas e a segunda avalia esta interação com a introdução, em cada ponto de suporte no SP, de um S1GL com suportes únicos ou com multi- suportes. As respostas estruturais são obtidas por integração direta da equação de movimento do sistema sujeito a dois acelerogramas simultâneos, nas direções horizontal e vertical. Os resultados são analisados e comparados para identificação das principais tendências das análises e esclarecimento dos efeitos envolvidos. Estuda-se, também, a importância de não- linearidades concentradas nos suportes da tubulação, tendo- se em vista o nível sísmico a que as centrais nucleares brasileiras estão sujeitas.
The results presented in this work refer to the investigation of the mechanics of the interaction between two important systems of nuclear power plants, i.e.: the Primary (PS) and Secondary (SS) systems. The influence of these effects on the response spectra is studied, in convenient points of the structure where could exist pipeline (SS) supports. Two different approaches are used to generate the response spectra: the first neglects the interaction between the two systems and the second considers this interaction by the addition, to every support point on the PS, of a single-supported or multi-supported SDOF system. The structural responses are obtained by the direct integration of the Primary System equations of motion subjected to two simultaneous design acceleration time-histories, in the horizontal and vertical directions. The results are analyzed and compared to identify the general trends of the solutions obtained by the two types of analysis, and to detect their effects on the SS response. The study is concerned, also, with the importance of nonlinearities concentrated in the pipeline supports; in the case of the Brazilian nuclear power plants.

Apresenta-se um estudo de avaliação dos critérios e métodos que são empregados atualmente na análise e projeto dos sistemas de tubulação nas usinas nucleares assim como a verificação da aplicação de alguns dos novos critérios apresentados pela comunidade técnico-científica internacional, dentro do método de análise modal-espectral. Estudam-se os tópicos da interação entre o sistema de tubulação e a estrutura que o suporta mediante o uso de espectros acoplados, a consideração do efeito do deslocamento relativo dos apoios da tubulação, usando-se espectros que o consideram ou uma excitação espectral múltipla, a introdução da combinação dos máximos modais dependendo da posição relativa das suas freqüências e a inclusão da resposta espectral correspondente aos modos de alta freqüência ou modos rígidos. A ferramenta básica de análise é constituída pelo programa computacional ANSYS. A avaliação é feita sobre parâmetros de esforços internos em trechos de um modelo de um sistema real de tubulações da usina nuclear brasileira, Angra 3. Os padrões são obtidos por análises no tempo de cada modelo sob o acelerograma de projeto. Conclusões são apresentadas sobre as atitudes mais convenientes para a atual conjuntura brasileira de projeto.
The main concern of this work is with the application of the modal spectral seismic analysis to secondary structural systems of nuclear power plants, with the large amount of conservatism which is included in them, and, of course, with the consequences to the particular case of the plants under construction in Brazil. One considers the design analysis methods which have been used so far in Brazil, as well as the most recent developments in the area, in USA and in Europe, to conclude about the adequacy of those procedures and recommend eventual changes to them. One then studies the subjects of the coupling effect between the primary and secondary system responses, the influence of the piping support relative displacements, the contribution of the cross-correlation among response modal components and the participation in the overall response of the so-called rigid modes. The main computer program aid is taken from an ANSYS-2 version and one uses a reduced model of a piping system as the secondary system and a 3-D beam element model of a reactor building as the primary system. The spectral analysis results are compared to time domain solutions using the same structural models excited by a design accelerogram. Conclusions and recommendations are oriented to the present design practice in Brazil.

Résumé :
Flow-induced vibration of hot-leg pipings is one of concerns for the design of Japan Sodium-cooled Fast Reactor (JSFR) which is now being developed. The flow field in the hot-leg pipings is supposed to be affected by flow disturbances at the entrance, so it is important to evaluate flow fields including the upper plenum. In this study, a simulation model of the upper plenum and the hot-leg piping system of JSFR was developed. Unsteady fluid flow analyses were then conducted by unsteady Reynolds averaged Navier-Stokes simulation (URANS) with Reynolds stress model. The appropriateness of the calculated results was discussed by comparing available scale model test results. Furthermore, a prototype model for vibration analysis of the hot-leg piping was developed. In the model, the transient pressure data predicted by the URANS were used as input data for the vibration analysis. The number of element was significantly reduced from that of CFD model by considering the correlation length of stress fluctuation. In addition, a stress mapping tool from a CFD model to a model for vibration analysis was created.

Résumé :
Piping analysis and its corresponding design evaluation according to ASME are complicated and tedious. One typical reason is the modeling of supports and their design evaluation. It is not exaggerated if one claims that this part of the work can consume about 1/3 of the total budgeted costs that are needed for a piping system analysis. The engineering practices of how a support should be modelled in a piping analysis differ between different regions in the world. The difference arises mainly from in what way the following two parts are weighted in a piping analysis: (1) the dynamic interaction effect between supports and piping, and (2) the big safety margin or, in other words, the conservatism, for a piping system which fulfills ASME’s requirements. In this paper a review of these practices will be first given and, thereafter, an analysis of piping-support interaction will be carried out, and finally our suggestions will be given. Some practical examples from recent projects in Nordic countries will be discussed.

Résumé :
It is becoming important to carry out detailed modeling procedures and analyses to better understand the actual phenomena. Because some accidents caused by high-frequency vibrations of piping have been recently reported, the clarification of the dynamic behavior of the piping structure during operation is imperative in order to avoid such accidents. The aim of our research is to develop detailed analysis tools and to determine the dynamic behavior of piping systems in nuclear power plants, which are complicated assemblages of different parts. In this study, a three-dimensional dynamic frame analysis tool for wave propagation analysis is developed by using the spectral element method (SEM) based on the Timoshenko beam theory. Further, a multi-connected structure is analyzed and compared with the experimental results. Consequently, the applicability of the SEM is shown.

Résumé :
Abstract The growing use of tubular structures in nuclear reactor facilities such as pipes, conduits and ducts that are buried underground, requires more detailed stress analysis to demonstrate structural integrity as required by Section III of the Boiler Pressure Vessel Code and other applicable industry codes. Thermal behavior of the pipe and soil interference can be conservatively evaluated by implementing the thermal characteristics and properties of the pipe into the expressions, as deduced by previous studies, which are made for the seismic analysis of buried piping. This paper presents procedures to evaluate the different pipe/soil parameters to be applied in those expressions, and explains these equations from designers perspectives and, finally, suggests an approach to combine various pipe stresses to check against ASME Boiler and Pressure Vessel Code Section III. The analysis assumes that the soil is linearly elastic and homogenous and the structure is a straight slender solid or hollow beam with a uniform, symmetrical cross section that satisfies the conditions of the elementary theory of beams on elastic foundations.

Résumé :
Abstract This study describes the results of seismic analyses conducted to clarify the effect of the plastic deformation of a pipe and its support structures on the seismic response of the entire piping system. The first type of analyses includes the investigation of plasticity with regard to the following parameters: (1) none, (2) piping, (3) support structure, and (4) piping and support structure. The second type of analyses includes the parametric survey of the yield load and post-yield stiffness of the restoring force characteristics of support structures. The results of the first type of analyses have demonstrated significant implications on the seismic design of piping systems based on the elastic-plastic response analysis. First, the piping response, i.e., elbow strain, is significantly reduced when plasticity is considered in the piping support. On the contrary, the piping support response is not so much affected by the piping plasticity. The results of the second type of analyses showed that the yield load of the support structure significantly affects the response of the piping system, whereas the post-yield stiffness does not affect much compared with the yield load.

Résumé :
Abstract Refractory is commonly used in pipes for cold wall design. Generally, to analyze refractory lined piping, a piping stress analysis is done using commercially available piping flexibility analysis software. In the stress analysis, the refractory weight and stiffnesses are included in the piping model. From the piping analysis, the calculated sustained and expansion stresses are compared with ASME B31.3 [1] allowable stresses and the forces and moments from the analysis are used in the design of attached equipment (vessel nozzle, valves, expansion joints etc.) piping restraints and supports. In this paper it will be shown that for a piping stress analysis, using the combined stiffness of the refractory and pipe material on the straight section of the pipe is satisfactory but when it is used on the bends, it will result in un-conservative resultant forces and moments from thermal expansion. To obtain satisfactory resultant forces and moments, the calculated refractory stiffnesses on the bends should be increased in the piping model. The piping stress analysis results were verified with finite element results and past experimental work.

The following paper presents a global methodology to analyze the set of results generated by a probabilistic analysis. The approach regroups traditional analyses such as Sensitivity Analysis (SA), Uncertainty Analysis (UA), and stability analysis as well as sensitivity studies (both deterministic and probabilistic) with enhanced sampling techniques (double loop to separate aleatory from epistemic uncertainty, importance sampling, adaptive sampling) in an incremental set of steps, with the goal to give the analyst and decision maker the most comprehensive and defensible collection of results. An example using the xLPR code and a selected scenario is used to illustrate each step of the approach.

Résumé :
Piping in a nuclear power plant is usually laid across several floors of a single building or adjacent buildings, and is supported at many points. As the piping is excited by a large earthquake through multiple supporting points, seismic response analysis by multiple excitations within the range of plastic deformation of piping material is necessary to obtain the precise seismic response of the piping. The verification of the dynamic analysis method of piping under an elastic domain, which is excited by multiple seismic inputs, was performed in our study last year and the correspondence of a piping response between an analysis and an experiment have been confirmed [17][18]. However, few experiments under plastic deformation conditions have been performed to verify the validity of multiple excitation analysis under a plastic deformation range. To obtain better understanding of the behavior of piping under a large seismic input, it is important to investigate the seismic response by multiple excitations and to verify the validity of the analytical method by multiple excitation experiments. This paper reports the validation results of the seismic elastic-plastic time history analysis of piping compared with the results of the shaking test of a 3-dimensional piping model under a plastic deformation range using triple uni-axial shake table. Three directional strains from the analysis and the experiments were compared in order to validate the analysis method. As a result, it is confirmed that the elastic-plastic analysis by time history excitation shows good agreement with the test results.
