La surgénération, caractéristique des réacteurs à neutrons rapides. Le cœur de tout réacteur nucléaire est le siège de destruction de matière fissile par absorption (fission ou capture) de neutrons par des noyaux fissiles et de production de matière fissile par capture de neutrons par des noyaux fertiles. Le rapport entre la production et la destruction de noyaux fissiles est appelé taux de régénération dans les RNR ou taux de conversion dans les REP. 5, record 2, French, - r%C3%A9acteur%20surg%C3%A9n%C3%A9rateur%20rapide

In the most common type of high temperature reactor(HTR) fuel, tiny particles of nuclear fuel are coated with three or four layers of coatings which are impenetrable to fission products up to a temperature of 2000 celsius. About 20, 000 particles, bonded with graphite are massed together to form a spherical fuel element with a diameter of about 6 centimeters. The high temperature reactor... might contain 100, 000 or more of these fuel elements. 5, record 3, English, - fuel%20pebble

The pebbles are... designed to passively limit the amount of heat unleashed by the nuclear fission reactions that drive the reactor. 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 3, English, - fuel%20pebble

The International Nuclear Event Scale [INES]. Level 7. Major accident. Criteria. External release of a large fraction of the radioactive material in a large facility(e. g. the core of a power reactor). This would typically involve a mixture of short and long-lived radioactive fission products(in quantities radiologically equivalent to more than tens of thousands of terabecquerels of iodine-131). Such a release would result in the possibility of acute health effects; delayed health effects over a wide area, possibly involving more than one country; long-term environmental consequences. 1, record 11, English, - %20major%20accident

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 13, French, - surg%C3%A9n%C3%A9rateur%20rapide%20refroidi%20par%20m%C3%A9tal%20liquide

Significant temperature gradients are present across the fuel particles when a nuclear reactor is producing power. If local temperatures are sufficiently high, nuclear fuel kernels can migrate up the thermal gradient. During this process, the barrier retaining fission product is progressively damaged, and the damage can lead to complete failure of the coating system.
