We don't use Westinghouse fuel anymore. Sorry I can't help much more than that.

STP has been experiencing a difference between predicted cycle lengths and actual EOC burnup (specifically, over-predictions of cycle length). This effect seems to have begun when we started using 1.5x (B-10 loading) IFBA. Westinghouse uses their APA package for our core design. Has any other utility had a similar experience?
