OPERATING PROCESS FOR A NUCLEAR REACTOR AND A REACTOR FOR APPLICATION OF THIS PROCES
Patent
·
OSTI ID:4730448
An operating process for a nuclear reactor consists in guiding nuclear fuel elements through the reactor core so that each fuel elemert passes successively through regions where it is submitted to neutron flux of different irtensities. Suitably the fuel elements are displaced along conical spirals disposed concentrically with the vertical reactor axis. Generally a number of these spiral fuel elemert paths are disposed one within another. According to an embodiment, ball-shaped fuel elements are guided within spiral tubes partially filled with the same liquid occupying the remaining reactor core. Above the liquid level within the tubes an inert gas serves for maintaining this level constart. At each of the lower ends of the tubes a lock-chamber is provided so that one element or several elements simultaneously can pass through it. (IIB)
