G0-1-82-Oll8, RW Root to RH Faulkenberry, dated April 2, 1982 In reference 1), the Supply System informed your office of a potentially l
reportable deficiency under 10CFR50.55(e) and references 2), 3), 4),
j
- 5) and 6) were interim reports on the subject condition.
l In reference 3), the Supply System committed to providing quarterly j
updates on the status of the subject deficiency. Our previous quarterly
)
updates have included two (2) Attachments. Attachment A was a detailed I
l recap of the problem and Attachment B identified the systems to be re-analyzed and the associated percent complete.
Because Attachment A does not change between reports, it is no longer included as part of our status reports. However, we will continue to provide semiannual updates to Attachment B.
Should circumstances arise where we find it necessary to amend Attachment A, we will so notify your office.

Based on the current WNP-1 construction slowdown, the level of effort expended to complete the analysis verification and redesign has been reduced. As a result, the Supply System interim reports will be provided i
on a six month basis.
If you have an questions or desire further information, please advise.
