Classification Calculations for the ORNL HFIR's Beryllium Reflector Number 3

摘要

HFIR utilizes a large beryllium reflector that encompasses the reactor core. Nuclear transmutations caused by activating the beryllium results in radioactive nuclide buildup. Gases created in the beryllium cause the reflector to swell and crack and thus dictate the life of the reflector. The beryllium reflectors are therefore replaced periodically and the disposition pathway of the irradiated beryllium must be determined.
