5/7/09 Telecom - RAI for Pilgrim PRR-19, Jet Pump Instrumentation Nozzle Weld Repair Plan

Walt, As we discussed during today's conference call, please provide a supplemental response for the subject submittal dated May 1, 2009, to address the NRC staff's questions shown below.
1. Clarify the paragraph at the top of page 1 of Attachment 2 to Enclosure 1. The second sentence states, The area limitation in Attachment 3 is 500 square inches. Is Attachment 3 referring to ASME Code Case N-638, Revision 3?

If not, please explain what is being referred as Attachment 3.

2. What evidence (e.g., operating experience) is there that the existing Alloy 82 weld overlay will maintain its integrity for the life of the plant, i.e., has there ever been a field or laboratory failure of this material in a boiling-water reactor environment? In support of this response, please provide the reference to Section V.A.2.(b) on page 8 of PRR-19, i.e.,

the documentation that supports the sentence, Buisine, et al. evaluated the IGSCC resistance Also, revise the reference list shown on page 1 of PRR-19 to include the EPRI Topical Report MRP-115 and all other applicable references used to address this question.

3. Provide dates for each of the references shown on page 1 of PRR-19.
Thanks, Rich Guzman Sr. Project Manager US NRC NRR/DORL 301-415-1030 Richard.Guzman@nrc.gov E-mail Properties Mail Envelope Properties ()
