Supplemental Information for Response to NRC Request for Additional Information, dated March 30, 2006, Related to Oyster Creek Generating Station License Renewal Application (TAC No. MC7624)
Reference:
(1) "Request for Additional Information for the Review of the Oyster Creek Nuclear Generating Station, License Renewal Application (TAC No.
MC7624),* dated March 30, 2006 (2) Response to NRC Request for Additional Information related to Sections 4.2 and 4.7 of the Oyster Creek Generating Station License Renewal Application (TAC No. MC7624), dated April 26,2006 In the reference (1) letter, the NRC requested additional information related to Sections 4.2 and 4.7 of the Oyster Creek Generating Station License Renewal Application (LRA). Reference (2) provided the information requested by the NRC staff, however, as noted in the response to RAI 4.2.2-1, AmerGen planned to supplement the response with the results of the calculations of the Upper Shelf Energy equivalent margin analysis for non-limiting reactor vessel beltline materials.
The results of these additional calculations are provided In the enclosure.
If you have any questions, please contact Fred Polaski, Manager Ucense Renewal, at 610-765-5935.
I declare under penalty of perjury that the foregoing is true and correct.
