Production test IP-377-A, Irradiation of N-Reactor inner fuel tubes in the KER Loops

摘要

The objective of the production test detailed in this report is to evaluate the behavior of N-Reactor inner fuel tubes during irradiation in the KER Loops at conditions equivalent to those expected in the N-Reactor. Natural and .947% enriched Zircaloy-2 jacketed N-Reactor inner fuel tubes (NIN-1) and (NIE-1) will be irradiated in the KER Loops to exposures no greater than 3500 MWD/T. The elements have brazed end closures and Zircaloy-2 supports and are contained in Zr-2 flow distributing sleeves.
