Radial power distribution. The primary goal was to estimate the minimum radial assembly peaking factor. The primary motivation for flattening the power distribution is passive cooling after shutdown … Power redistribution limited the ability to flatten the power distribution. Shorter cycle lengths would limit this effect, but were not analyzed. The power distribution map is a color-coded sixth core map. The peak to average assembly power density for each assembly is provided with colors split into seven color-coded groups ... 3, record 1, English, - power%20distribution%20map

Abstract.... Pressurised light Water Reactor(PWR) are the most common nuclear reactors used today. It is necessary for each neutronic code to be validated for this type of reactor. The goal of this work is to create a complete calculation scheme which can be applied to the evolution of the core of a pressurised light water nuclear reactor using the lattice code DRAGON and the reactor code DONJON. Each step of this scheme will be validated by comparisons with other codes or with experimental results. The unit cell calculation will be computed for a benchmark … The assembly calculations will be used to compare the results given by DRAGON, APOLLO2 and MCNP [codes] for an assembly used by EDF [Électricité de France] for code testing. The core calculations will show that the codes DRAGON and DONJON can produce accurate macroscopic results for a real core. 1, record 8, English, - assembly%20calculation

In the monolithic type pebble bed reactor, the dimension of the reactor core diameter becomes large, and nuclear control for a large-sized reactor having a large output scale is insufficient in a cooled state using only control elements(control rod, boron sphere) inserted into the reflector region. Furthermore, a reactor core control rod, which is forcibly inserted directly into the reactor core, is required in addition to the control elements inserted into the reflector region by gravity drop only. Moreover, cases have been reported that fuel spheres are broken if the control rod is inserted forcibly into the core because the pebble reactor core is full of fuel spheres accumulated inside the reactor core, which causes a serious drawback. 1, record 13, English, - pebble%20bed%20reactor%20core

The fissionable material is divided into groups of 100 million billion uranium-235 atoms scattered within a 0. 5 mm sphere of uranium dioxide. That core is coated with four containment layers.... Some 15, 000 carbon-coated uranium dioxide kernels, looking like nuclear poppy seeds, are embedded in a tennis ball-size graphite and resin matrix. Graphite acts to slow the fission neutrons and so acts as an embedded moderator. The matrix is then encased in a 5 mm pure carbon shell, sintered, annealed, and machined to a uniform diameter of 6 cm. 2, record 14, English, - fuel%20pebble

[...] un système interne, mesurant le flux neutronique à l'intérieur du cœur, et un système externe placé à l'extérieur de la cuve coexistent. La terminologie habituellement retenue pour nommer les systèmes à partir de trigrammes utilise l'appellation RIC (réacteur instrumentation coeur) pour le premier et RPN (réacteur protection nucléaire) pour le second. Le système RIC mesure la distribution relative en 3D de la puissance à l'intérieur du cœur du réacteur avec une très bonne précision liée à un procédé de mesure interne au réacteur. C'est pourquoi on l'appellera par la suite système de référence. La constante de temps associée n'est pas une exigence forte; elle dépendra de l'architecture du système et de la technologie utilisée. 3, record 15, French, - syst%C3%A8me%20RIC

Mesure bêta. Le principe de piégeage pour la mesure des aérosols bêta est similaire à celui utilisé pour la capture des aérosols émetteurs alpha. Néanmoins, les particules bêta ont un parcours dans l’air beaucoup plus important pouvant atteindre plusieurs mètres pour certains émetteurs. Les phénomènes d’absorption dans le filtre et dans l’air séparant le filtre du détecteur ne sont donc pas autant cruciaux que dans le cas de la détection des particules alpha. En revanche, la détection des particules bêta est très sensible au rayonnement gamma, car ce dernier peut déclencher au niveau de la chambre de détection les mêmes phénomènes électriques qu’une particule bêta. 2, record 40, French, - chambre%20de%20d%C3%A9tection

La caractéristique essentielle d'un réacteur surgénérateur est qu'il produit plus de combustible qu'il n'en consomme grâce à l'absorption des neutrons excédentaires par un matériau qui, lui-même, se transformera en matériau fissile. Plusieurs types de réacteurs surgénérateurs sont techniquement réalisables. [...] Le système de surgénérateur sur lequel se sont concentrés les plus grands efforts de développement est le réacteur rapide à métal liquide (LMFBR). Pour obtenir le maximum de plutonium-239, la vitesse des neutrons provoquant la fission doit rester élevée, avec une énergie égale ou proche de leur énergie initiale. Tous les matériaux modérateurs qui pourraient ralentir les neutrons, comme l'eau, doivent être exclus du réacteur. On utilise le sodium liquide qui a de très bonnes propriétés de transfert thermique. Le sodium se liquéfie à environ 100 °C et n'entre en ébullition qu'à partir de 900 °C. Ses principaux inconvénients sont sa grande réactivité chimique avec l'air et l'eau et son niveau élevé de radioactivité induite dans le réacteur. Le développement des surgénérateurs rapides à métal liquide a commencé aux États-Unis vers 1950. 2, record 47, French, - surg%C3%A9n%C3%A9rateur%20rapide%20refroidi%20par%20m%C3%A9tal%20liquide

Each measuring channel includes a fuel assembly instrumentation tube inside the core of the nuclear reactor and a glove finger inside the instrumentation tube in which the fission probe moves. The neutron flux is measured in a set of fuel assemblies distributed throughout the section of the core. 1, record 54, English, - instrumentation%20tube

... the reactivity control of fission reactors. Conventional nuclear fission reactors are controlled by control rods which are mechanically moved within the reactor core to control reactivity by changing the amount of neutron absorbing material in the reactor fission volume. The control rods can introduce a sufficient decrease in reactivity to control the reactor during positive reactivity transients arising from changing operating conditions. 1, record 55, English, - reactivity%20control

In nuclear thermal propulsion, a propellant gas is heated as it flows through the core of a nuclear reactor and is then expanded and expelled through a rocket nozzle. The reactor core can be a solid(e. g., uranium carbide particles in a graphite matrix or uranium nitride in a ceramic matrix), liquid, or a gas/plasma. The last two approaches can produce much higher propellant temperatures, resulting in higher specific impulse and greater rocket efficiency. 2, record 61, English, - nuclear%2Dthermal%20propulsion

Neutron radiation is produced by the fission process in nuclear reactors. It is the form of radiation which can cause other materials to become radioactive. This property is used to create radioisotopes for medicine and industry.

Les neutrons peuvent aussi être très pénétrants. Ils sont produits par la fission dans les réacteurs nucléaires. Comme ils peuvent rendre d'autres matières radioactives, on les utilise pour préparer des radio-isotopes destinés à des applications médicales et industrielles. L'eau et le béton peuvent servir de bouclier efficace contre les neutrons qui proviennent du noyau des réacteurs. 3, record 71, French, - neutrons
