Exit Interview The inspection scope and findings were summarized on D1cember 4,1980, with those persons indicated in Paragraph 1 above.
The inspector also discussed the new enforcement policy.
3.
Licensee Action on Previous Inspection Findings a.
(Closed) Infraction 395/80-20-01, Failure to follow fitup procedures.
The inspector reviewed the licensee's response to Region II dated October 3,1980 and the design evaluation of the discrepant weld condition as documented by the GAI to SCE&G memo dated November 6, 1980 and the supporting documentation.
The corrective action program was also reviewed by another inspector on a previous inspection (IE Report 50-395/80-30).
The design evaluation concludes that the design conditions are met, the pipe stresses are within the allowable stresses, and the misalignment is accept-able as is.

Unresolved Items Unresolved items were not identifed during this inspection.
5.
Independent Inspection The inspector conducted a general inspection of the reactor, auxiliary and intermediate buildings to observe construction progress and con-struction activities such as welding, electrical installation, material handling and control, housekeeping and storage.
There were no items of noncompliance or deviations in this area of the inspection.
6.
Licensee Identified Items (LII),10 CFR 50.55(e) and/or Part 21.
The inspector reviewed the status of all open LII's with the QA staff, the newest LII's reported by the licensing engineer, and the October 31, 1980 revision to the Nuclear Engineering procedure NE-123, Processing and Disposition of Potential Significant Deficiencies and Substantial Safety Hazards. NE-123 provides for the implementation of the guidance provided by the Region II letter dated August 27, 1980 to the licensee relative to 10 CFR 50.55(e) and Part 21.
a.
(Closed) LII 395/80-05-07, Inadequate Drawings for Pipe Branch Connections.
The inspector reviewed the licensee's response to Region II dated March 21, 1980 and discussed the corrective action with the responsible staff.
As documented in Nonconfonnance Notice (NCN) No.1369 RI, the criteria for the reinforcing weld size has been revised, a reinspection program has established that all welds are acceptable and that no repairs are required to the branch connection welds.
Training for the engineering, QC and QA staff relative to this item has been conducted, b.
(Closed) LII 395/80-05-08, Bergen-Paterson Shock Arrestors.
The inspector reviewed the licensee's response to Region II dated March 10, 1980, reviewed NCN's, isometric and installation drawings and discussed the subject with the responsible engineering and QA personnel.
The inspector observed the installation work for the following shock arrestors as representative samples of the various problems, defects, size, and complexity of design changes cited in the licensee's response of March 10, 1980:
FWH-119, RHH-185, MSH-102, MSH-058, MSH-095, and RHH-292.
The inspector also observed similar shock arrestors in the same work areas that had not been modified.
c.
(Closed) LII 395/79/30-01 Containment Airlock.
The inspector reviewed the licensee's response to Region II dated January 30, 1980 and documentation attesting to the installation of a door cushioner system by the vendor.

d.
(Closed) LII 395/79-30-06 Feedwater Check Valve and Pipe Break.
The inspector reviewed the licensee's response to Region II dated September 27, 1979 and observed that new valves have been installed in each of the three loops to decrease the transient pressure pea ks.
Rockwell 18X16X18 check valves have been installed to replace the Anchor Darling valves originally installed.
The reanalysis of the feedwater system with the larger Rockwell valves indicates that the pressure peaks are now acceptable. The inspector reviewed isometics, weld reports and other documentation for check valves 1684 A, B, and C prior to observing the installed valves.
e.
(0 pen) LII 395/80-37-01 Broken Limitorque Torque Switches.
The licensee hr submitted a final report dated November 21, 1980 reporting a design change to replace torque switches with limit switches on three service water discharge butterfly valve limitorque operators.
f.
(0 pen) LII 395/80-37-02 Component Cooling Pumps Swing Interlock.
The licensee has submitted a final report dated November 21, 1980 relative to the omission of an interlocking contact in the swing component cooling pump. This condition prevented it from starting on a ioad sequencer signal when lined up as the primary pump.
g.
(0 pen) LII 395/80-37-03 Service Water Pump Speed Switch.
The licensee has submitted a final report dated November 21, 1980 relative to the omission of a seal in contact in the speed changing switches for the service water pumps.
