NRC Letter 99-452A Attached is the letter that was requested in our 8/22/02 phone call.

Page 6 of 12 has a discussion of the Lower Shell Longintudinal Weld L2 (Heat No. 299L44). The normalization method of the data is provided in this discussion.

Pages 21 through 24 of Appendix A has the credibility assessment.

Individual capsule T-cold temperatures are given on Page 21, Table 2.

The W1 capsule that was irradiated in Surry 2 is included in the data table of the attached letter. Please understand, however, that the data from Capsule W1 was not used in the results that were presented on behalf of the license renewal assessment. In other words, only 8 capsules were considered in the evaluation of the weld heat 299L44 material.
