Clarification to Application for Ginna Relief Request No. 19 Tom -

Thank you for providing the email below.

The NRC staff is currently reviewing R.E. Ginna Relief Request No. 19, Fourth Interval ISI Program - Defer Reactor Pressure Vessel Category B-F Exams from 2009 to 2011 Outage, included in your letter of June 23, 2008 (ADAMS Accession No. ML081790151). The letter requests deferring in-service inspections of the pressure retaining dissimilar metal welds in the reactor vessel nozzles from the 2009 to the 2011 refueling outage.

During a phone call between the NRC staff and your staff on December 17, 2008, clarification was sought regarding the second sentence of paragraph 5.C.), "Deterministic Flaw Growth Analysis," (page 4 of 5 in the attachment to the letter referenced above). In the letter, this sentence reads as follows: "The welds for which the subject examinations are conducted are similar metal low alloy steel welds which are not susceptible to PWSCC."

Your staff indicated that the sentence was intended to read as indicated in your email below.

This clarification resolves the staff's concerns. As we discussed, I will include this email in ADAMS as a publicly available document.

Ginna RR 19 Here is the response to the question that was raised with regards to RR 19.

The second sentence of part C.), Section 5, of RR 19 (Page 4 of 5) was intended to state the following:

The welds for which the subject examinations are conducted are dissimilar metal stainless steel to low alloy steel welds which are not susceptible to PWSCC.

The actual material associated with the subject welds is detailed in our RAI response dated October 31, 2008."
