Licensee Action on Previous Insoection Findings a.

(Closed) Noncompliance (320/77-02): Failure to identify non-conforming conditions on Main Steam and Emergency Feedwater lines during final inspection by Field QC. The Inspector was informed by the licensee's representatives that the final inspection of the Main Steam line had not been completed at the time this noncompliance was identified. The inspector had asked if this inspection was complete prior to making nis own inspection and understood from information furnished him that it had been completed.

The inspector concluded that this item resulted from a misunderstanding and observed that the non-conforming conditions had been recorded on the Phase I punch-list. With respect to the Emergency Feedwater line the inspector found that hanger EFH-455 had been reinstalled, reinspected and the as-built condition had been approved by Engineering.

The final inspection checklist had been revised to require re-inspection of areas which may be affected by rework following final inspection.

b.

(Closed) Noncompliance (320/77-02): Failure of Field QC to identify unapproved methods of attaching electrical cable (

trays and to supports within enclosures.

The inspector found

that: (1) Nonconfoming attachment of cables to cable trays had been identified on Deviation Report (DR) No. 0684 for correction prior to final acceptance of the cable, (2) the construction procedure has been revised to permit use of temporary tie down rods for attachment of cable to cable trays during cable pulling, (3) attachment of cable within the enclosure had been approved by Engineering and (4) Electrical QC personnel have been instructed to document any temporary or unapproved installations and to bring any unclear items to their supervisor's attention.

c.

(Closed) Noncompliance (320/77-02): Discrepancy between the requirements of Specification 2555-70 and Procedures ECP-8-2 and ECP-3-2 for fire barrier materials and insulation of cable teminations to bus bars, and failure of Field QC to identify lack of specified insulation at temination of circuit HH 30 P. The inspector found that: (1) ECP-8-2 had been revised to meet specification requirenents for fire barrier materials, (2) ECP-3-2 had been revised to meet specification require-ments for insulation of cable teminations, (3) the checklist for ECP-3-2 has been revised to require verification of cable l

temination insulation by Field QC, (4) verification of cable temination insulation has been added to the requirenents of QC Phase I inspection and (5) lack of heat shrink insulation at the cable to bus bar connection of circuit HH 30 P has been identified as a punch list item on the Phase I turnover inspection (systen EF 59-10E)

d.

(Closed) Noncompliance (320/77-02): Failure to perform liquid penetrant or magnetic particle examination of weld repair cavities.

The inspector found that radiographic examination of the cavities and the repaired welds had been performed with acceptable results.

Although the requirement of the applicable procedure were not complied with, the welds were found to be accepta bl e.

e.

(Closed) Unresolved Item (320/74-04): Stress analysis of Main Steam and Pressurizer relief valve piping. Stress analysis of Main Steam relief valve piping had been closed previously.

(320/76-12). The inspector observed that Report No. 7.00.006, Rev.1, " Pressurizer Relief Valve Discharge Piping Stress Analysis" which had been released by Burns and Roe (B&R) on March 21,1977 had been reviewed and accepted by GPUSC.
