TUCOP failure threshold test CO6R

Conference ·
OSTI ID:6188112
The C06R test was the sixth single-pin test in the collaborative US/UK PFR/TREAT transient testing program. It was designed to study the mechanism, time and location of cladding failure and first fuel escape in an intermediate channel transient undercooling - overpower accident (TUCOP). It complements the LO5/sup 2/ and LO7/sup 3/ tests which studied post failure fuel dispersal in a similar hypothetical accident. The test fuel was a single irradiated driver fuel pin taken from the UK's Prototype Fast Reactor (PFR) after approx.4% peak burnup. The C06R test has produced evidence that both pre and post failure internal fuel motions produce net fuel worth decreases that would help mitigate a TUCOP accident in an LMFBR. Furthermore, the high axial failure location will prevent worth increases even if emergent fuel momentarily accumulates at the failure site before it disperses upward.
