Flow Accelerated Corrosion (FAC) is the most prevalent material degradation mechanism for low carbon steel in steam-water flow systems. The band of uncertainty in predictions of wear rate due to FAC spans one to two orders of magnitude. Such a wide range of uncertainty inhibits the ability to devise safe and economical repair and replacement schedules. The goal of this thesis is to reduce uncertainty of predictions of wear caused by FAC. Reduction in the uncertainty in FAC wear rate predictions is achieved through the development of a new predictive FAC model, the incorporation of this model in a flow system analysis environment, and the use of this environment to identify improved methodologies for predicting FAC wear rate. The new FAC model is based on a published empirical model, published data, and physical mechanisms identified to be significant in the wear process. The new FAC model is shown to have less uncertainty for single phase lab data and single and two phase plant data. The flow system analysis environment is an interactive program that calculates parameters relevant to the FAC phenomenon based on plant description. Functionality of this environment is validated for each of the four calculations it performs: thermodynamic, thermal hydraulic, chemistry, and degradation rate. Additionally, this environment can be used to analyze contributions to uncertainty that are not yet identified. This environment was used to analyze the contribution to uncertainty from the current method of incorporating chemistry parameters in predictions of FAC wear. Based on this analysis, suggestions are made to improve these methods, thereby reducing prediction uncertainty and improving the knowledge necessary for safer and more economical plant operation.

Hydrodynamic analysis of two models of the Offshore Floating Nuclear Plant [91 was conducted. The OFNP-300 and the OFNP-1100 were both exposed to computer simulated sea states in the computer program OrcaFlex: first to sets of monochromatic waves, each consisting of a single frequency and waveheight, and then to Bretschneider and JONSWAP spectra simulating 100-year storms in, respectively, the Gulf of Mexico and the North Sea. Hydrodynamic coefficients for these simulations were obtained using a separate computer program, WAMIT. Both models exhibited satisfactory performance in both heave and pitch. An alternative design of the OFNP-300 was developed and similarly analyzed in attempt to further improve hydrodynamic performance. A catenary mooring system was designed and analyzed for both plant models. The number of chains and the length of each were selected to ensure the mooring systems would withstand, with sufficient margins of safety, the maximum tension produced in a 100-year storm. This analysis was conducted both with all the designed mooring lines intact, and with the worst-case line broken. A lifecycle cost analysis of various mooring systems was conducted in order to minimize the cost of the mooring system while maintaining adequate performance.

The effect of aging on nuclear power plant performance has come under increased scrutiny in recent years. The approaches used to make an assessment of this effect strongly influence the economics of nuclear power plant operation. This work aims (a) to determine how the risk-informed approach to performance assessment can be specifically improved, (b) to formulate and demonstrate a method for risk-informed nuclear power plant component reliability analysis, and (c) to assess the applicability of these improvements to the nuclear regulatory environments of the United States and France, the countries having the largest national nuclear power programs. In order to address the first objective, a case study of the U.S. and French regulatory treatment of the pressurized thermal shock phenomenon was performed. A new methodology that can be applied to the construction of risk-informed analyses was developed in response to the findings of the case study. The methodology specifically aims to improve upon current risk-informed methods, which implement a hybrid of best-estimate and conservative modeling, by increasing the use of risk-based modeling justification in order to allow for the development of a more logically consistent analysis. The second objective is addressed through the development of a new reliability model describing the effects of transient-induced degradation. The reliability model is applied through the demonstration of a risk-informed method for the calculation of fatigue degradation. The data requirements for the future successful implementation of this risk-informed method are presented. Examining the applicability of the risk-informed approach to U.S. and French nuclear power plant regulation showed that currently the U.S. is a more progressive implementer of risk-informed practices. This examination revealed, however, than an alternative approach known as the best-estimate plus uncertainty (BEPU) method could be considered for application in regulatory environments, such as in France, that are less accepting of the risk-informed approach. In order to understand how the BEPU method could be improved, the U.S. approach to BEPU was analyzed and recommendations for its future application are presented.

This thesis details the ongoing development of a new Offshore Floating Nuclear Plant (OFNP) concept that exhibits a promising potential for economic and rapid deployment on a global scale. The OFNP creatively combines state-of-the-art Light Water Reactors (LWRs) and floating platforms similar to those used in offshore oil and gas operations. A reliable and cost-effective global supply chain exists for both technologies, which enables a robust expansion in the use of nuclear energy on a time scale consistent with combating climate change in the near future. The OFNP is a plant that can be entirely built within a floating platform in a shipyard, transferred to the site, where it is anchored within 12 nautical miles (22 km) off the coast in relatively deep water (=/> 100 m), and connected to the grid via submarine AC transmission cables. Shipyard construction ensures a supply of qualified workers and facilities, and it brings mass-production-like construction efficiency to existing reactor designs. Eventual shipyard decommissioning allows sites to immediately return to a "green field" condition when the plant's life is spent. The crews would operate in monthly or semi-monthly shifts with onboard living quarters, similar to oil and gas platforms. The OFNP is a nuclear plant specifically designed for the global market: it can be constructed in one country or multiple countries and exported internationally. It lends itself to a flexible and mobile electricity generation strategy, which minimizes the need for indigenous nuclear infrastructure in the host country and does not commit the customer to a 40 to 60 years-long project.

Perfect plant operation with high safety and economic performance is based on both good physical design and successful organization. However, in comparison with the affection that has been paid to technology research, the effort that has been exerted to enhance NPP management and organization, namely human performance, seems pale and insufficient. There is a need to identify and assess aspects of human performance that are predictive of plant safety and performance and to develop models and measures of these performance aspects that can be used for operation policy evaluation, problem diagnosis, and risk-informed regulation. The challenge of this research is that: an NPP is a system that is comprised of human and physics subsystems. Every human department includes different functional workers, supervisors, and managers; while every physical component can be in normal status, failure status, or a being-repaired status. Thus, an NPP's situation can be expressed as a time-dependent function of the interactions among a large number of system elements. The interactions between these components are often non-linear and coupled, sometime there are direct or indirect, negative or positive feedbacks, and hence a small interference input either can be suppressed or can be amplified and may result in a severe accident finally. This research expanded ORSIM (Nuclear Power Plant Operations and Risk Simulator) model, which is a quantitative computer model built by system dynamics methodology, on human reliability aspect and used it to predict the dynamic behavior of NPP human performance, analyze the contribution of a single operation activity to the plant performance under different circumstances, diagnose and prevent fault triggers from the operational point of view, and identify good experience and policies in the operation of NPPs.
(cont.) Regarding the human reliability analysis function, the partial Standardized Plant Analysis Risk Human Reliability Analysis (SPAR-H) method was applied. Performance Shaping Factors (PSFs) were employed to analyze the influence of human performance indicators already existing in ORSIM. Based on the human performance model, an operation case study was investigated. A series of carefully chosen candidate policies were tested on a computerized model that represents the structure, processes, and interactions of the underlying target NPP systems. These candidates included: (1) New management system application; (2) Personnel population change, (3) Planning delay, and (4) Tolerance to surprise workload.

In historical and current experience, the economics of nuclear power have proven to be problematic for utility companies. Construction costs and schedules have proven to be highly unpredictable, with the average reactor construction project costing two to three times more than its initial budget and taking almost twice as long to complete as expected. The causes of this phenomenon have not been well-characterized, even two decades after the last new reactor was brought online in 1996. Scenario generation can provide useful information about the economic viability of nuclear construction projects over a variety of parameter spaces without having to make prescriptive assertions about likely single values for delay and other difficult-to-predict parameters. The MEERKAT model creates scenarios over two different reactor types (Westinghouse AP1000 and NuScale SMR plant); three delay cases (optimistic, median, and pessimistic based on historical data); and six different utility company credit ratings (which translate into varying costs of capital). MEERKAT outputs the levelized cost of electricity (LCOE) for each scenario and compares them to average electricity prices for a number of regions in the United States. These scenarios produce levelized costs of electricity (LCOEs) that are not competitive in a deregulated market in any case, and which may be competitive in regulated markets under certain optimistic conditions. If the AP1000 is considered as more credit-stressful than the SMR project, the SMR becomes more competitive with the AP1000, but the projects' viability in the wider market remains unchanged. However, in general terms the smaller up-front cost of the SMR makes it a more feasible endeavor for a wider variety of utility companies, increasing the potential customer base for nuclear power generation units.

This study mainly investigates the three-dimensional packaging problem for the decommissioning nuclear power plant unit. The constraints include active conditions and weight limitations of the given containers. The objective is to minimize the number of given containers to reduce the storage space and costs. To ensure the safety and smoothness of decommissioning work of nuclear facilities and to find out the optimal spatial configuration, this study explores the heuristic algorithms and deterministic algorithms for placing dismantling units to improve space utilization rate. The proposed method can effectively solve the problem to reduce the packing cost. Several numerical examples are presented to illustrate the effectiveness and efficiency of the proposed method.

On 2011 March 11, a strong earthquake induced several large waves of tsunami hit the east coast of Japan. The tsunami caused extensive damage to the site of Fukushima Daiich Nuclear Power Plant (NPP). Fukushima Daiichi NPP employed BRW4 reactor with MARK I containment, which is identical to the design of Chinshan NPP of Taiwan Power Company. In the present study, an input deck of MELCOR based on the design of Chinshan NPP is construct to simulate the Fukushima Daiichi Unit 3 accident. In the simulation, the timings of water injection, depressurization, and containment venting are set as specified in the official Japanese government report about the accident. The results of simulation demonstrate that the hydrogen burns observed during the accident are not predicted by the code. The the reactor pressure vessel and the containment are remain intact throughout the accident. As predicted in the MELCOR simulation, there is 67 kilogram of hydrogen leak into the reactor building. Nevertheless, the concentration of hydrogen is still too low to induce hydrogen burn. There is no radionuclide release to environment in the base case simulation due to that the reactor building is kept intact up to the end of the simulation. In a sensitivity study, it is assumed that the reactor building breaches at the time specified in the official government report, The results show that 1.3% of Xe is released to the environment. The releases of other radionuclides are very minor. The results of MELCORE simulation of the accident are compared with the results of MAAP5 simulation. The differences are very significant. The results of MAAP5 simulation indicated that the reactor building breached due to the pressure spike predicted at 68.2 hours after scram, which was caused by the relocation of molten core from core region into vessel lower plenum.

As far as power system operation is concerned, it is very important to set up enough spinning reserve to avoid an unexpected generator breakdown and the lack of electricity which comes from load forecast error. Therefore, the power company must establish a set of planning principles to make sure that the power system is capable of running safely, supplying sufficient power, maintaining superior power quality and reducing the cost of electricity. Taiwan Power Company is expected to start commercial operation for the first unit of Lungmen nuclear power plant in 2012 and the second unit will start in 2013. The largest generator in the system will be Lungmen nuclear power plant whose rated capacity is 1350MW in place of Kuosheng nuclear power plant whose rated capacity is 985MW and the capacity will be increased nearly 40%. However, if Lungmen nuclear power plant has a power outage, it is possible to have under-frequency load shedding considered in a low load in winter during a year. This thesis uses the load-frequency sensitivity factor which was provided by Taiwan Power Company to calculate the lowest frequency of each period in winter when Lungmen nuclear power plant has a breakdown and to estimate whether there is the possibility of having under-frequency load shedding or not. If it does, pumped storage units will be taken as instantaneous reserve therefore the reliability of power system can improve dramatically during this period. As a result, systems can reduce the arrangement of frequency regulating reserve and save the cost of electricity. This thesis also uses PSS/E simulation software to analyze the change of power flow after Lungmen nuclear power plant is incorporated into Taiwan Power System. When Lungmen nuclear power plant break down, firstly, the software will simulate the shift of system frequency and check whether the frequency regulating reserve is sufficient or not. Secondly, the change of power flow is analyzed after generators have been increased capacity. Finally, the reasonable unit commitment is suggested.

For a nuclear power plant (NPP), there are three power uprate levels: Measurement Uncertainty Recapture (MUR), Stretch Power Uprat (SPU), and Extended Power Uprate (EPU). The purpose of this study is to analyze the stability of a light water reactor which is under power uprate condition (MUR). In this study, we are focusing on the stability issue such as monitoring the status of a power uprated core and the precautions against the operation point entering the unstable region, etc. The computer code --- LAPUR5.2 is chosen as the tool for calculation. Based on the data from KuoSheng (Unit I) and ChinShan (Unit II) nuclear power plants, four operation points are calculated by LAPUR5.2 for assumed power uprate tasks. These simulation results are compared with the results from other U.S. NPPs which have successful experience in power uprate. Some stability problems which may take place in Taiwan’s NPP during the power uprate tasks are discussed in this study. The research results show that a limited power uprate (MUR), usually within 2% of the core power level, will not make the decay ratio exceed 0.8. In many simulation cases the decay ratio is much less than 0.8. Therefore, it is certain that MUR can hardly affect the stability of a nuclear power plant.

The coast of large-scale 9.0 earthquake occurred at northeastern in Japan, at 14:46 11/03/ 2011, which was an about 40.1 m high tsunami, and fire and nuclear accident. In addition, resulted in local function paralysis and accident renewed a question about nuclear security in Taiwan. Although there are the public protective work and the emergency evacuation plan for the nuclear accident, the public lack a process of the nuclear accident evacuation in current internal nuclear accident. However, an authority is not clear enough to the nuclear safety operations. In this research, first, we studied the legislations of a nuclear accident, and clarified the responsibilities and norms on central government and local government. And then we looked back the relevant nuclear accident and nuclear accident operating procedures, which conduct analysis to find out trouble spots. According to nuclear power problem, the plant could be improved; In this study, we study deeply the students of the nuclear accident evacuation operating procedures. By interviewing with scholars and relevant units reviewed the research proposed nuclear power plant outside the plant operating procedures to evacuate peoples and students evacuation procedures at trouble spots and defects, according to recommendations given by scholars operating procedures on the amendment, the final conclusions recommendations.

This article explores the position and attitude of legislators whose constituency is used to be the location of Fourth Nuclear Power Plant. The study finds that the legislative participation of legislators in Taipei County can be analyzed by three stages. The first stage starts from 1st February 1990 to 26th October 2000. Before the DPP government announces the Fourth Nuclear Power Plant shutdown, the legislative participation of DPP legislators in Taipei County is much more aggressive than KMT legislators in the same county. The second stage starts from 27th October 2000 to 11th March 2011. After the Fourth Nuclear Power Plant was shut down and before 311 incident ago, the legislative participation of DPP and KMT legislators in Taipei County are much more passive than before. The third stage starts from 12th March 2011 to 12th April 2013. After 311 incident, DPP legislators in New Taipei City regain power coming from anti-nuke people, which makes their attitude become aggressive. But KMT legislators in New Taipei City seldom take part in the legislative participation still, and they go to vote for the bill of the Fourth Nuclear Power Plant in Legislative Yuan only when KMT do political mobilization.

Abstract Since 1970s,It has been exceeding thirty years when Taiwan initiated the public basic construction of the nuclear power. Though it enhanced economic development and brought along change of industrial structure,it caused all walks of life to call in question the quality of safety and the quality of environment for the nuclear power,it would like whirlpool to lead into much impurity continuously and become more and more magnification. So,the development of the nuclear power,after the fourth nuclear power plant built in 1980,following up intervening strongly of political power and social power,they made the fourth nuclear power plant which its public controversy possessed the quality of science technology didn''t "de-politicized",therefore;it missed the solve juncture to seek for the way of technological specialization. The Democrative Progress Party(DPP)Which flaunted "anti-nuclear" held power in 2000,it changed the budget bill of the fourth nuclear power plant,which had finished the executing and legislative process,caused the controversy to rrise again. Although the Executive Yuan declared the fourth nuclear power plant to build again,the controversy of the nuclear power still existed,it had never obtained the unanimous understanding of the ruling party and the opposite party and all people. It still leave foreshadowing of anti-nuclear plebiscite?What kind of appropriate nuclear power policy for our future policy in Taiwan? Therefore, from the pointview of political economy, the purpose of this study is to investigate the relationship between the electricity construction and the energy development, on the development and argument of the fourth nuclear power plant. Four factors─ Politics & Society, Economics, Technology & Security, and Ecology & Environmental Protection─are used to discuss the two themes of this study─the argument of the fourth nuclear power plant and the development of nuclear power. It will be verified from the “State Theory” and the “Government-interfering Theory.” Chapter III is the discussion on the energy policy from the hydraulic and thermal electrogeneration to nuclear power. It also discusses the fourth nuclear power plant project from Chiang Ching-Kuo to Chen Shui-Bian; furthermore, it makes a “history-structure” analysis. Chapter IV illustrates the dispute of the fourth nuclear power plant, between the Executive Yuan and the Legislative Yuan. Then, it searches for a suitable theory to analyze the dispute. Chapter V will explore the electric power energy after the fourth nuclear power plant project, and evaluates the practicability of substitute program (it contains mainly the independent power plants, the reproducible energy, and the energy retrenchment.) Understanding the importance of nuclear power, the goal of nuclear power development is to promote an electric power policy balanced among industry, energy, and environmental protection. Chapter IV will review the argument and the substitute program of the fourth nuclear power plant. Furthermore, it proposes a conclusion and a prediction on the future of Taiwan’s nuclear power development, including the solution to the dispute, the prospect of electric power energy, the practicability of substitute program.
