Licensee Action on Previous Inspection Findingr (0 pen) Item 339/77-37-01, E&DRC Review, Unit 2 a.
As noted in IE Report 50-339/77-37, Details I paragraph 6.g(3), VEPC0 committed to review all Engineering and Design Coordination Reports (E&DCR's) which had been written on Category I Unit 2, as well as Unit 1, equipment to assure that they had been completed or otherwise resolved prior to initial criticality. The Unit I review by NRC inspectors is reported in IE Report 50-338/78-04.
The inspector and the NRC Resident Inspector (NRC:RI) reviewed the VEPCO and S&W documentation that establishes the review program (March 15, 1978, VEPCO to S&W), the S&W review program (March 24, 1978, S&W to VEPCO), the categorization of E&DCR's (S&W internal memos dated April 19 and April 24, 1978), the applicability of Unit 1 E&DCR's to Unit 2 (S&W int ernal memo dated June 12, 1978) and interim status reports of the review work (S&W internal memos dated April 24 and June 1, 1978, and an undated summary issued about mid-June 1978). The inspectors reviewed the S&W review program which was conducted in three phases: (1) Verify the accuracy of the identification of Unit 2 Category I E&DCR's by S&W Construction and Fischback & Moore (F&M) personnel; (2) Verify the accuracy of the S&W Site Engineering Office's (SEO) categorization review within the S&W Release Status Facility (RSF) files and in conjunction verify work completion through S&W Field Quality Control (FQC) acceptance signatures on the documents; and (3) Insure the proper identifi-cation of all old E&DCR's and Field E&DCR's not under computer listings.
The S&W (Boston) Engineering Assurance (EA) group audited the SE0 activities related to Unit 2 E&DCR's on June 20-22, 1978 (report 12050-057) and reaudited the same activity on December 4-8, 1978.
The inspector reviewed the audit report 12050-057 and the documen-tation of the followup work and the review by FQC of the corrective action by SEO. The inspector discussed with the VEPCO Resident QA Engineer the findings and observations of the December 4-8, 1978, audit wherein the EA audited 500 E&DCR's.
The ins, 'or reviewed the S&W Nuclear Project Operating Procedure (POP) No. POP-500 " Field Procedure for the Control and Flow of Engineering and Design Coordination Reports (E&DCR's)" Revision 1 issuad rabiuary 2, 1978, and Revision 2, issued November 7, 1978, and PDF,17 " Document Control", Revision 1, issued June 30, 1978.
Work related to E&DCR's has been reviewed by the RII inspector as part of the review of QA program activities as reported in IE Reports Nos. 50-339/78-4, 78-6, 78-1 RII Rpt. No. 50-339/78-36 I-3 The inspector and the NRC:RI selected a random sample of twenty-two Category I E&DCR's and the inspector reviewed the E&DCR's and the corrective action that completed the requirements for the E&DCR's listed below.
The inspector also made field obse rvations of representative work and discussed the subjects with appropriate SE0 and FQC personnel as appropriate.

Unresolved Items There were no new unresolved items identified during this inspection.
4.
Independ_at Inspection The i pector toured the Unit 2 facility, observed work inside the conta ment vessel and in the auxiliary building, talked to various craft personnel, and discussed the schedule for work to be performed with the VEPCO Senior Resident Engineer, and the NRC Resident Insp-ctor.
No items of noncompliance or devia: ions were identifie. RII Rpt. No. 50-339/78-10 I-4 5.
Review of QA Manual, Inspection and Enforcement History The inspector performed a review of the QA manuals and docket files to inc.lude the following: inspections relative : QA programs and site act'eities; enforcement correspondence and responses; the construction de ntciency file, and the status of construction.
The inspector's review of the VEPC0 QA manual indicates that VEPC0 has developed and is adequately executing a QA program consistent with the SAR commitments relative to design, procurement, construction, enforcement response, and the reporting of deficiencies. The QA organization has remained relatively stable. The surveillance of the QA activities of the construction contract work has continued consistent with the status of the project, procedural changes have been incorporated to eliminate repetitive deficiencies and/or otherwise increase the effectiveness of the execution of the overall QA program.
No items of noncompliance or deviations were identified.
6.
Licensee Identified Items VEPC0 has reported a number of items to Region II as reportable items in compliance with 10 CFR 50.55(e) and/or 10 CFR 21, and the inspector reviewed the items noted below and the supporting documentation, and discussed the items with responsible staf f during the inspection.
