- 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 ()
