Abstract:
The minimum mass for a critical reactor is well studied whereas the minimum heat production from a nuclear reactor has received little attention. The thermal power of a (sub)critical reactor originates from fission as well as radioactive decay. Fission includes neutron-induced and spontaneous fission. For an idealized critical core, we find that the minimum theoretical power is ER/Λ, whereas for a subcritical reactor comprising fissionable material undergoing spontaneous fission, the minimum power is dictated by subcritical multiplication. Interestingly, radioisotopic heat generation exceeds the minimum theoretical fission power for most of the fissile materials examined in this study.

Abstract:
Fission modeling in general-purpose Monte Carlo transport codes often relies on average nuclear data provided by international evaluation libraries. As such, only average fission multiplicities are available and correlations between fission neutrons and photons are missing. Whereas uncorrelated fission physics is usually sufficient for standard reactor core and radiation shielding calculations, correlated fission secondaries are required for specialized nuclear instrumentation and detector modeling. For coincidence counting detector optimization for instance, precise simulation of fission neutrons and photons that remain correlated in time from birth to detection is essential. New developments were recently integrated into the Monte Carlo transport code TRIPOLI-4 to model fission physics more precisely, the purpose being to access event-by-event fission events from two different fission models: FREYA and FIFRELIN. TRIPOLI-4 simulations can now be performed, either by connecting via an API to the LLNL fission library including FREYA, or by reading external fission event data files produced by FIFRELIN beforehand. These new capabilities enable us to easily compare results from Monte Carlo transport calculations using the two fission models in a nuclear instrumentation application. In the first part of this paper, broad underlying principles of the two fission models are recalled. We then present experimental measurements of neutron angular correlations for 252Cf(sf) and 240Pu(sf). The correlations were measured for several neutron kinetic energy thresholds. In the latter part of the paper, simulation results are compared to experimental data. Spontaneous fissions in 252Cf and 240Pu are modeled by FREYA or FIFRELIN. Emitted neutrons and photons are subsequently transported to an array of scintillators by TRIPOLI-4 in analog mode to preserve their correlations. Angular correlations between fission neutrons obtained independently from these TRIPOLI-4 simulations, using either FREYA or FIFRELIN, are compared to experimental results. For 240Pu(sf), the measured correlations were used to tune the model parameters.

Abstract:
Fission of fissile uranium or plutonium nucleus in nuclear fuel results in fission products. A small fraction of them are volatile and can migrate under the effect of concentration gradients to the grain boundaries of the fuel pellet. Eventually, some fission gases are released to the rod void volumes by a thermally activated process. Local transients of power generation could distort even further the already non-uniform axial power and fission gas concentration profiles in fuel rods. Most of the current fuel rod performance codes neglects these gradients and the resulting axial fission gas transport (i.e., gas mixing is considered instantaneous). Experimental evidences, however, highlight axial gas mixing as a real time-dependent process. The thermal feedback between fission gas release, gap composition and fuel temperature, make the “prompt mixing assumption” in fuel performance codes a key point to investigate due to its potential safety implications. This paper discusses the possible scenarios where axial transport can become significant. Once the scenarios are well characterized, the available database is explored and the reported models are reviewed to highlight their major advantages and shortcomings. The convection-diffusion approach is adopted to simulate the axial transport by decoupling both motion mechanisms (i.e., convection transport assumed to be instantaneous) and a stand-alone code has been developed. By using this code together with FRAPCON-3, a prospective calculation of the potential impact of axial mixing is conducted. The results show that under specific but feasible conditions, the assumption of “prompt axial mixing” could result in temperature underestimates for long periods of time. Given the coupling between fuel rod thermal state and fission gas release to the gap, fuel performance codes predictions could deviate non-conservatively. This work is framed within the CSN-CIEMAT agreement on “Thermo-Mechanical Behaviour of the Nuclear Fuel at High Burnup”.

Abstract:
A novel experimental approach for studying dissipative effects in nuclear fission has been developed at GSI, Darmstadt. Fragmentation of radioactive heavy-ion beams is employed to prepare fissile nuclei in well-defined initial conditions and the fission-fragment nuclear charge distribution is used for investigating pre-saddle dynamics in detail. The undeniable manifestation of transient effects at high temperature is demonstrated and the influence of the initial deformation is clearly evidenced for the first time.

Abstract:
During the COVID-19 lockdown, as households were kept separate in a bid to contain the coronavirus, morally underpinned dynamics of fission and fusion occurred, privileging the ‘nuclear family’, which is taken here in two senses: the conventional social unit of a couple and their children, on the one hand, and the togetherness promoted by the nuclear industry in North West England, on the other. Whilst Sellafield’s Nuclear family fused with its host community in an outpouring of corporate kindness and volunteering, singles bereft of nuclear families were fissioned off from social life, which led to a corrective debate in the Netherlands. Drawing out analogies from a modest comparative perspective, I posit the nuclear family as a prism affording insights into the corporate, governmental and personal management of intimacy.

Abstract:
A decommissioning of nuclear fuel cycle facilities is inseparable from the problems of radioactive waste disposal. One of these problems is the categorization of a waste according to the content of beta- and alpha-emitters. Beta-emitters can be identified by existing technologies; however, the trouble arises when detecting alpha-emitting elements, primarily the long-lived members of the actinium chain with the specific activity of kBq/kg when they are spread inside a structural material. The report considers an application of an active neutron method-a differential die-away technology for reliable control of small quantities of FM. The essence of this method consists in sounding the interrogated item by pulsed thermal neutrons and recording the induced fission neutrons. The ratio of the number of fission neutrons to the number of source neutrons gives the normalized number of fission neutrons that is linked to the FM mass in the interrogated object. The work presents the scheme and principle of operation of an experimental device, as well as the results of measurement of concrete structures that contain internal traces of fissile materials. Analysis of the results shows that the proposed method allows the detection of ~ 6 mg of fissile material per kg of concrete with possible localization (cartogram) of the contaminated area.

Também, foram interpretadas informações experimentais referentes aos estados isoméricos do 237.ANTPOT Pu e 239.ANTPOT. Pu. Com relação ao potencial preditivo do formalismo, foram identificados os possíveis candidatos (spin e paridade) a estados isoméricos no 241.ANTPOT Np, bem como foi calculada também pela primeira vez a distribuição de momentos de nêutrons para o 239.ANTPOT Np fora da deformação de equilíbrio.
It was developed, implemented and tested a formalism suitable to the description of nuclear properties at non equilibrium deformations regime, by using the Macroscopic-Microscopic method in association with the Combined Semimicroscopic Method. This formalism was used for the interpretation and elucidation of some open problems, as the structures in the 237Np photofission cross section, photofission angular distributions of 239Pu, and the concentrations of low-energy Ml transitions in 237Np and 239Pu. Also, experimental information on 237Pu and 239Pu isomeric states was interpreted. Concerning the prediction potentialities of the formalism, were identified possible candidates (spin and parity) for the 241Pu isomeric states, as well as the 239Pu neutron momentum distributions, at non equilibrium deformation, was also calculated for the first time.

Abstract:
Despite it being recognised as a problem worthy of consideration over a century ago, we have little mechanistic understanding of how the size of a cell’s nucleus is determined. The simply shaped fission yeast Schizosaccharomyces pombe is genetically tractable and undergoes a closed mitosis, making it a useful system in which to probe mechanisms of nuclear size control. In S. pombe cells, nuclear volume scales with cell volume, and not DNA content, across a wide range of cell volumes and throughout the cell cycle, maintaining a constant nuclear volume to cell volume (N/C) ratio. This thesis explores the mechanisms by which this scaling is achieved, using physiological, genetic and biochemical approaches. N/C ratio is perturbed and resultant nuclear and cellular growth rates of individual cells are assessed. N/C ratio homeostasis is observed. Both high and low aberrant N/C ratios correct rapidly in individual cells. Analysis of the kinetics of N/C ratio recovery is carried out and mathematical models of nuclear size control are proposed. To identify molecular components and biological processes with roles in nuclear size control mechanisms, a genetic screen for deletion mutants with aberrant nuclear size and biochemical analysis of a nuclear size mutant are carried out. Ribosome biogenesis, RNA processing and nucleocytoplasmic transport are all implicated in nuclear size control.

Abstract:
A General Description of Fission Observables (GEF) version 2016/1.2 is a software which simulates various types of fission. The main objective of this project is to compare the proton induced fission with the neutron induced fission of the same fissioning system. The proton induced fission was recently introduced to GEF and is relatively untested. Furthermore another task is to study the energy dependence in the same compound nucleus. The project will focus on simulating and comparing 238U(p,f) with 238Np(n,f) and 239Np*(f) as well as 232Th(p,f) with 232Pa(n,f) and 233Pa*(f ). The simulations were also compared to experimental data acquired by the division of applied nuclear physics at Uppsala University. The results show that the p-induced channel behaves very similar to the Compound Nucleus (CN) channel in contrary with the (n,f) channel. However when comparing the simulated data to the experimental data, there seems to be clear differences.

Abstract:
Simultaneous measurements of the angular distribution, mass distribution and average total kinetic energy of fission fragments produced by the neutron-induced fission of 235U and 232Th have been made using a gridded ionisation chamber. The neutron energy range used was thermal to 1.9 MeV for 235U and 1.4 to 1.7 MeV for 232Th. The following topics were investigated: the interdependence of the fission fragment angular and mass distribution; the anomalous behaviour of fragment anisotropy for 235U(n,f) at neutron energies En below 150 keV; the possible existence of a third symmetric mass peak for 232Th(n,f); the mass fine structure in 235U(n,f) and 232Th(n,f); and the dependence of the fission fragment average total kinetic energy on the excitation energy of the fissioning nucleus. For this study, mono-energetic neutrons were produced by the and reactions. Four signals produced by the fission chamber were fed into a data acquisition system and processed by a specially modified comprehensive computer program. The results indicate that there is no interdependence between the angular and mass distributions of fragments for 235U(n,f) and for 232Th(n,f). The angular distribution of 235U fission fragments showed an anisotropy of less than one for En below 150 keV. For 232Th, the expected minimum in the anisotropy near En = 1.6 MeV was confirmed. No evidence for a third peak in the mass symmetry region of 232Th(n,f) was observed, within the yield sensitivity limitation of the chamber. Fine structure was observed in the mass yield distributions for 235U(n,f) and 232Th(n,f) at mass locations predicted by theory. The fission fragment average total kinetic energy for 235U(n,f) and 232Th(n,f) showed no significant dependence on the excitation energy of the fissioning nucleus. Possible reasons for some of these results are advanced.

Abstract:
Cytoplasmic dynein is a ubiquitous minus-end directed motor protein that is essential for a variety of cellular processes ranging from cargo transport to spindle and chromosome positioning. Specifically, in fission yeast during meiotic prophase, the fused nucleus follows the spindle pole body in oscillatory movements from one cell pole to the other. The three molecular players that are essential to this process are: (i) the motor protein dynein, which powers the movement of the nucleus, (ii) microtubules, which provide the tracts for the movement and (iii) Num1, the anchor protein of dynein at the cortex. Dyneins that are localized to the anchor protein at the cortex and simultaneously bound to the microtubule emanating from the spindle pole body, pull on that microtubule leading to the movement of the nucleus. The spindle pole body, by virtue of its movement establishes a leading and a trailing side. Previous work by Vogel et al. has elucidated the mechanism of these oscillations as that of asymmetric distribution of dynein between the leading and trailing sides. This differential distribution is a result of the load-dependent detachment of dynein preferentially from the trailing microtubules. This self-organization model for dynein, however, requires a continuous redistribution of dynein from the trailing to the leading side. In addition, dyneins need to be bound to the anchor protein to be able to produce force on the microtubules. Anchored dyneins are responsible for many other important processes in the cell such as spindle alignment and orientation, spindle separation and rotation. So we set out to elucidate the mechanism of redistribution of dynein as well as the targeting mechanism of dynein from the cytoplasm to cortical anchoring sites where they can produce pulling force on microtubules. By employing single-molecule observation using highly inclined laminated optical sheet (HILO) microscopy and tracking of fluorescently-tagged dyneins using a custom software, we were able to show that dyneins redistributed in the cytoplasm of fission yeast by simple diffusion. We also observed that dynein bound first to the microtubule and not directly to the anchor protein Num1. In addition, we were able to capture unbinding events of single dyneins from the microtubule to the cytoplasm. Surprisingly, dynein bound to the microtubule exhibited diffusive behaviour. The switch from diffusive to directed movement required to power nuclear oscillations occurred when dynein bound to its cortical anchor Num1. In summary, dynein employs a two-step targeting mechanism from the cytoplasm to the cortical anchoring sites, with the attachment to the microtubule acting as the intermediate step.

Abstract:
The rhodium speciation in nitric acid has been identified, primarily by the use of 103Rh Nuclear Magnetic Resonance Spectroscopy. The results have indicated that the rhodium species in stored high level waste (HLW) will range from the hexaaquo ion, {Rh(H20)6}3+-to complexes of the general formula {Rh(H20)6-n(NO2)nl(3-n)+, depending on the nitrite ion concentration. The solvent extraction of these complexes by dinonylnaphthalene sulphonic acid and various organo-phosphine sulphides has been investigated, and an integrated scheme for recovering rhodium from HLW is proposed.

Abstract:
O Brasil planeja construir uma planta de produção do 99Mo por fissão do 235U, devido à crescente utilização deste radioisótopo no setor de medicina nuclear. Neste trabalho buscou-se estimar as características físico-químicas e radiológicas dos rejeitos radioativos que serão gerados em tal instalação, além de fornecer subsídios teóricos a serem utilizados na definição do gerenciamento desses rejeitos. Estabelecidos dois cenários de produção para este projeto e utilizando-se o código Scale®, foram calculados os inventários radioisotópicos dos fluxos de rejeitos. Considerando-se o processamento químico dos alvos de urânio, foi possível caracterizar os rejeitos a partir de suas características químicas e radiológicas. Utilizando-se o software MicroShield®, determinou-se então as concentrações de atividade desses rejeitos em até 3 meses de produção. Este trabalho ainda apresenta o cálculo das taxas de dose variando-se tanto a espessura da blindagem, a ser utilizada numa embalagem para transporte in-site, quanto a quantidade de rejeito líquido retido em tal embalagem. Os radionuclídeos responsáveis pela maior parcela da dose de radiação foram identificados de forma a facilitar a determinação do método mais apropriado para o gerenciamento dos rejeitos após sua separação e antes de seu armazenamento. Os resultados aqui apresentados constituem uma compilação inicial do que é esperado em termos de rejeitos radioativos líquidos numa planta produtora de 99Mo e podem auxiliar no desenvolvimento do plano de gerenciamento de rejeitos de tal instalação.
Brazil intends to build a facility for the 99Mo production through 235U fission, once this radioisotope is largely used in nuclear medicine. This study aimed at estimating the physical, chemical and radiological characteristics of radioactive waste expected to be generated in that facility, and to provide theoretical subsides that can be used on the definition of a proper waste management system. Two production scenarios were established and the radioisotope inventories of the wastes were calculated by Scale®. From the chemical processing of the uranium targets the wastes were characterized on their chemical and radiological features. MicroShield® was used to determine the activity concentrations up to three months of 99Mo production. In addition, this work presents dose rate calculation for several sizes of shielding and different amount of wastes, collected in a proper package for in-site transportation. Radionuclides responsible for higher doses were identified in order to facilitate choosing the most appropriate method for managing the wastes after their chemical separation and before their storage. These results are part of what is expected on radioactive wastes at a 99Mo production facility and might help on the development of the waste management planning for that facility.

Abstract:
(I) J'ai étudié les mécanismes contrôlant la congression des noyaux pendant la conjugaison de la levure S. pombe. A l'aide d'imagerie à long terme basée sur la microfluidique, j'ai mesuré la durée précise de la congression nucléaire et démontré que deux moteurs moléculaires des MTs, la dynéine et la kinésine-14 Klp2 contribuent à ce processus, dans des voies parallèles. La dynéine s’associe aux SPBs. Son niveau au SPB dépend de la chaine légère intermédiaire Dli1 qui pourrait potentiellement stabiliser le complexe dynéine et est requise pour la congression. Klp2 se localise sur les MTs. La localisation différentielle des deux moteurs suggère des rôles distincts pour tirer les noyaux l'un vers l'autre. Klp2 pourrait induire le glissement de MTs antiparallèles émanant des SPBs, alors que la dynéine localisée au SPB pourrait tirer sur des MTs émanant du SPB opposé.(II) J'ai caractérisé un nouveau facteur morphogénétique, l’AAA+-ATPase Knk1, qui promeut la croissance linéaire chez S. pombe. L’absence de Knk1 provoque la formation d’un coude à proximité des extrémités cellulaires. Ce défaut ne résulte pas de défauts des MTs, qui participent à la linéarité de la croissance. Knk1 se localise aux extrémités de la cellule indépendamment des MTs et des câbles d’actine. Cette localisation requiert son N-terminus et est renforcée quand le domaine ATPase C-terminal lie l’ATP. La concentration de Knk1 aux extrémités est aussi contrôlée par Sla2 et Cdc42, de manière anti-correlée, et indépendamment de l’endocytose. Enfin, Knk1 oscille périodiquement entre les deux extrémités, indépendamment des oscillations de Cdc42, suggérant l'existence d'au moins deux systèmes oscillatoires séparés
(I) I studied the molecular mechanisms underlying nuclear congression during fission yeast conjugation. Using microfluidic-based long-term imaging, I defined the precise timing of nuclear congression compared to cell mating and found that two MT molecular motors, dynein and the kinesin-14 Klp2 promote nuclear congression in parallel pathways. Dynein associates with SPBs. Dynein level at SPBs is controlled by the light intermediate chain Dli1 that may promote stabilization of the dynein complex and is essential for dynein-dependent nuclear congression, while dynactin is surprisingly not required for this process. Klp2 localizes along MTs. These differential localization patterns suggest distinct roles for the two motors in pulling the nuclei together: Klp2 may slide anti-parallel MTs emanating from the SPBs, while dynein at the SPB may pull on MTs emanating from the opposite SPB.(II) I characterized a novel morphogenetic factor, the AAA+-ATPase Knk1, supporting linear growth in fission yeast. knk1Δ cells display a kink close to cell tips, a unique shape phenotype that is neither caused by defects in behavior of MTs that promote linear extension. Knk1 localizes to cell tip independently of MTs and actin cables. This localization is mediated by Knk1 N-terminus and enhanced upon ATP binding to Knk1 C-terminal ATPase domain. Knk1 tip levels are enhanced in a sla2 or cdc42, independently of Sla2 role in endocytosis. Finally, Knk1 oscillates between the two cell tips in an anti-correlated periodic manner possibly uncoupled from Cdc42 oscillations suggesting the existence of at least two separated oscillatory systems contributing to fission yeast morphogenesis
