Hello all,
at Cook Unit 1, we experienced 7 fuel defects in the previous fuel cycle, so our 'tramp' or 'background' levels are a little higher than we have seen in recent history.
Has anyone made attempts to reduce the 'background' or 'tramp' levels at their site?
thanks,
wvf

For the last few refueling outages, Surry has a new strategy on cleaning up the RCS involving more effective crud burst and cleanup which is designed to lower source term. It has been very successful.

Beaver Valley Power Station Units 1 & 2 response:
Beaver Valley had grid to rod fretting fuels 2-3 cycles ago, however these did not create a large increase in tramp since these are tight defects and primarily radiogases escapes from the fuel rods. We did have an open defect that caused the loss of material many years ago at Unit 1 (1986) and we actually vacuumed the bottom of the reactor vessel. I believe this was a baffle jetting fuel failure. Other than the latest chemistry shutdown initiatives, we have not performed any other activities specifically for tramp reduction.
