Dear Sir or Madam:
By Reference 1, Entergy submitted Pilgrim Relief Request (PRR) No. 12 for NRC review and approval for the 4th ISI interval that began on July 1, 2005. The relief requested included provisions that were incorporated in ASME Code Case N-623. This code case is acceptable for use as stated in NRC approved Regulatory Guide 1.147, Revisions 13 and 14. It has subsequently been annulled since its provisions were incorporated into the 2001/2003 version of the ASME Code Section Xl, Division 1.
Regulatory Guide 1.147, Revision 13, which lists Code Case N-623 as acceptable for use was the approved Guide in place at the time Entergy submitted the Pilgrim ISI program and associated PRR-12 for NRC review and approval in June 2005 (Ref. 1). The use of Code Case N-623 is referenced on page 1-25 of Reference 1.
Since Code Case N-623 was acceptable for use at the time Reference 1 was submitted, Entergy withdraws PRR-12 and will continue to use the ASME Code Case N-623 for the 4th ISI interval as an acceptable alternative pursuant to 10 CFR 50.55a(a)(3)(i). It was authorized in R.G. 1.147, Revision 13 pursuant to 10 CFR 50.55a (a)(3) and stipulated in 10 CFR 50.55a.
This use of ASME Code N-623 is consistent with the NRC guidance cited in the third paragraph (page 3) of R. G. 1.147, Rev. 14.
