Examination of BeO irradiated at elevated temperatures in the engineering test reactor

Abstract

A description is given of an examination of BeO samples irradiated by the General Electric Co. in the Engineering Test Reactor, Idaho Fails, to doses up to 1.2 x 1021(> 1 MeV) and temperatures in the range 470 — 1200ºC, at dose rates of 1 to 3 x 1014 nv. The results of X—ray measurements and optical and electron microscopy are presented and discussed. Comparisons are made with previously reported results on similar material irradiated in the reactor HIFAR at lower dose rates.
