PLANT V0GTLE, UNIT 1 READINESS REVIEW MODULE 13C-CHAPTER 7.0 INDEPENDENT DESIGN REVIEW (IDR)
INSPECTION OF IDR RESULTS AND CORRECTIVE ACTIONS 1.
Background At a meeting with the NRC in Bethesda, Maryland on June 20, 1985, the Georgia Power Company (GPC) presented a plan as part of their Readiness Review program for an Independent Design Review (IDR) of Plant Vogtle Unit 1 (Vogtle) to be performed by Stone and Webster Engineering Corporation (SWEC). The IDR for all non-civil / structural design aspects would be presented in a single review docu-ment or module. The IDR associated with the civil / structural design would be in modules #1, #8, #13A, #138, and #13C. The NRC Office of Inspection and Enforcement activities related to the Vogtle IDR for civil / structural modules may include, in addition to a review of Chapter 7 of the module, an inspection to determine the thoroughness of the IDR contractor's review, review of findings and review of GPC's corrective actions.
2. Purpose
"
The purpose of this inspection was to review Chapter 7.0 of Readiness Review Module #13C " Post Tensioning Containment".
Specifically, SWEC's depth of review
-
was evaluated by selecting certain calculations and independently reviewing them.
A review of the IDR findings and associated GPC corrective actions was performed to verify their validity and implementation.

Personnel Contacted The following is a list of personnel contacted during the inspection.
Name Organization and Position W.C. Ramsey GPC, Readiness Review Manager.
J.W. Curtin SWEC, IDR Module 13C Team Leader.
R.W. McManus GPC, Readiness Review Civil Discipline Leader.
'
G. Creighton GPC, Civil Readiness Review Team Member.
4.
Genera? Conclusions The IDR on Module 13C was performed competently and effectively. The review of Specification X2CJ2.10.4 was particularly well done.
There were four findings on this specification relating to inconsistencies with calculations and/or FSAR commitments; however, all of them were editorial in nature having no technical significance. GPC had submitted an amendment to the FSAR to correct these inconsistencies.
The NRC team reviewed the corrective actions and found that they satisfactorily resolved the findings, and considers these four findings to be closed.
Other findings concerning the calculations are identified as Comments 1 and 2, under specific comments.
