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 2, 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 2, English, - fuel%20pebble

Réacteurs refroidis par gaz. Les réacteurs à haute température refroidis par gaz (RHTRG) sont à l'étude depuis longtemps, et un certain nombre de prototypes ou de centrales de démonstration ont été construits, mais leur exploitation n'a pas été un succès total. Le RHTRG est pour l'essentiel un réacteur dont le modérateur est du graphite et le fluide caloporteur de l'hélium. L'emploi de ce gaz inerte, ainsi qu'une conception spéciale du combustible, permet d'exploiter le réacteur à des températures beaucoup plus élevées que celles des réacteurs refroidis par eau, de sorte que l'on peut produire de la vapeur à une température et à une pression elles aussi beaucoup plus élevées pour alimenter des générateurs de turbines à vapeur traditionnels, avec un rendement thermique nettement supérieur, ou produire de la chaleur industrielle à haute température pour des applications spéciales. 2, record 3, French, - r%C3%A9acteur%20%C3%A0%20haute%20temp%C3%A9rature%20refroidi%20par%20gaz
