ATTACHMENT A Nuclear Regulatory Commission Region V Suite 202, Walnut Creek Plaza 1990 N. California Boulevard Walnut Creek, California 94595 Docket Nos. 50-460 and 50-513 Construction Permit Nos. CPPR-134 and -174 1.
Resoonse to Item A of Notice of Violation The response indicates that a high percentage (i.e., 3 of 5) of pipe sucports checked by Surveillance Report #848 had loose or missing U-bolts, but does not identify any action to increase the sample size to establish or refute a basis for generic concern.
Additional Suonly System Resconse e
The relatively small sample size of pipe supports identified in reference
- 2) that were selected for reinspection was predicated on the fact that only five (5) of the pipe supports installed to date, with preliminary accept status, contained U-bolts.
On September 11, 1980, an inspection of all accessible pipe supports containing U-bolts was performed by Project Quality Assurance. The inspection was performed to determine if the installed condition, inspec-tion status and support of documentation were consistent with procedural i
requirements. Fif ty-nine (59) of the accessible pipe supports contained U-bo l ts. Only two (2) of the fif ty-nine (59) supports contained the preliminary acceptance tag and the remaining fif ty-seven (57) were still considered in-process. The JAJ inspection record check point for torquing of the two (2) preliminary accepted suppurts had been signed and accepted by JAJ QV. The documentation for the remaining fif ty-seven (57) supports indicated no QV acceptance. A verification of the installed condition confirmea the compliance to the procedural requirement.
Based on the results contained in Surveillance Report #913 dated September 11, 1930. it is our position that the condition identified in your letter is an isolated case and not a basis for generic concern.

Response to Findings Regardina Ineffective Corrective Actions The response generally verifies the long time differential existing between the identification of a problem situation and the resolution of that problem. The response, however, does not address any future actions to be taken by the Supply System to assure that effective and timely corrective actions will be taken and/or verified.

4 Additional Suoply System Resoonse The previous system of tracking NRC items was not effective for the standard of. performance anticipated by WPPSS management and the NRC.
i To improve our performance regarding ineffective corrective actions, we recently implemented a change to assign the responsibility to influence and emonasize the need to resolve NRC items quickly and effectively at the Project Managers level through a management system entitled:
"Mancging Project Level Action Requirements". To accomplish the imple-4 mentation of this new aoproach, Project Quality Assurance will coordinate the tracking of the Action Item / Critical Item and provide the results on an as-recuired basis to the Project Manager for his review with the responsible department.
Effective August 25, 1980 a new Planning / Measurements group became a functic.al and integral part of the WNP-1/4 QA department. This grouc will be staffed by Project Quality Assurance Specialists with various backgrounds and expertise. The principle functions of this group will entail detailed reviews of contractor performance for detection of trends, assessment and overview of the adequacy of contractor inspection effec-tiveness. This group will also coordinate project level action require-ments as they apply to Project Quality Assurance with particular emphasis on Regulatory items. Performance standards for compliance and effective-ness of surveillance / audit programs will be developed to suit WPPSS Corporate policies.
