Post-Irradiation Examination Results from the BTF-105A LOCA/LOECC Test

Abstract

The BTF-105A experiment was conducted in the Blowdown Test Facility of the NRU reactor. This CANDU-Owners-Group-sponsored test was part one of two simulations of the latter stages of a Loss-Of-Coolant Accident (LOCA) with additional Loss-Of-Emergency-Core-Cooling (LOECC). The BTF-105A test assembly consisted of an instrumented fuel stringer containing a single, unirradiated, fuel element. The primary objective of the BTF-105A test was to evaluate the instrumentation and procedures to be used in the BTF-1O5B test. This paper presents post-irradiation examination results from destructive examination of the BTF-1O5A fuel stringer in the hot cells at the Chalk River Laboratories.
