RD. Ashley- additional questions Page 111 From: D. Ashley To: John Hufnagel Date: 11/07/2006 1:42:18 PM

Subject:

additional questions John-Two more questions from ACRS to add to the list that I sent earlier.

1) Since water collected from the drywell sand bed region drains should be sampled prior to dicarding the contents of the collection containers--Did the analysis of the containers that were discarded during the recent NRC inspection suggest that the leakage is anything other than water from the reactor cavity region during the refueling flood Up?

2) It was stated by the applicant at the ACRS Subcommittee meeting on October 3, 2006, that the committment to seal the reactor cavity region with strippable coating was not carried out during two refueling outages because it was assumed at that time that the plant was to be decommissioned (1998-2000). Is it possible that the contents of the collection bottles was approximately 8 years old? Is ti possible that the leakage is occurring even though you are now (>2000), coating the cavity region during refueling outatges? Where could it be from?
