DOCKET N0. 50-445 LINER ATTACHMENT MATERIAL REQUIREMENTS: IMPACT TESTING SDAR: CP-87-22 (INTER,1M REPORT)
Gentlemen:
On June 17, 1987, ws verbally notified your Mr. Shannon Phillips of a deficiency involving FSAR and specification requirements regarding impact testing of materials attached to the containment liner.
Specifically, Section 3.8.1 of the FSAR and Specification 2323-SS-14 require notch toughness impact tests for materials attached to the containment liner.
One 3/4" plate, to which pipe support CT-1-031-010-C92S is installed, is attached to a 1" containment liner insert plate. The Mill Test Report for the 3/4" plate did not contain the results
- of the notch toughness impact test. This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e).
i Currently, an engineering evaluation of the materials and weld configurations for the attachment to the liner plate is in process. This evaluation is required to determine any safety significance and reportablity pursuant to 10CFR50.55(e).
We will provide our next report by August 31, 1987.
Very truly yours, W. G. Counsil
