Licensee Action on Previously Identified Items (Closed) Noncompliance (341/78-16-01): Failure to identify, report and take corrective action relative to the repair of weld No. E21-3147-0W2 on drawing No. 6M721-3147-1: The inspector reviewed the weld process control sheet traveler, weld repair record and the radiographic film. It was determined that applicable code and procedure requirements were met.
(Closed) Noncompliance (341/79-08-01): Unauthorized grinding: The inspector reviewed DDR No. 405, weld repair record. It was determined that the applicable code and procedure requirements were aet.
(Closed) Unresolved Item (341/79-08-02): Missing data sheet: The inspector reviewed DDR No. 391. It was determined that the weld data sheet could not be located and due to configuratica changes weld No. E21-3052-3WO was cut out. The inspector reviewed the new weld data sheet and determined the applicable ccde and requirements were met.

Review of Documents The inspector reviewed the following documents:
(1) The inspeictor established that W&B procedu e for controlling welding material has not been revised sinc. the last review (IE Inspection Report No. 50-341/79-08, paragraph 3.a) except that procedure No. WB-r 101 should be WB-Q-101.
(2) Receiving Inspection Report, Purchase Order and Material Certification for E7018 electrodes with heat No. 411E0311 and lot No. 02-3-S820S; E70S-2 welding rod with heat No.
065118 and ER308 welding rod with heat No. 7329-57.
It was determined that the above documents met the PSAR, 10 CFR 50, Appendix B and the applicable code requirements.
b.
Control of Materials The inspector toured the welding material issuing station. It was determined that (1) the welding materials were properly identified and segregated; (2) records are properly kept; (3)
issuance and return of welding materials are controlled in accordance with approved proceduras and (4) the temperature of the rod ovens is maintained except stainless steel rod oven No. 1. The temperature was approxiamately 95 degrees Fahrenheit instead of the 150 degrees Fahrenheit to 200 degrees Fahrenheit range as required by the procedure. The licensee initiated a hold status on both the oven and the contents.
No items of noncompliance or deviations were identified.

4.
Reactor Coolant Pressure Boundary Piping - Visual Examination of Welds The inspector visually examined the following completed welds:
(1) Residual Heat Removal System Welds No. E11-2298-3W4, No. E11-2299-3WF1, No. E11-2299-3WF2, No. E11-2299-01W3.
No. E11-2327-3W4, No. E11-2327-0W2, and No. E11-2298-5W0.
(2) Reactor Feedwater Supply System Weld No. N21-2336-6W7.
(3) Reactor Recirculating System Weld No. B31-GE761E21-FW-B17.
(4) Nuclear Boiler System Welds No. B21-2596-3WF4, No.
B21-3258-3W0 and No. B21-3258-2W0.
(5) High Pressure Coolant Injection System Weld No. E41-2297-4W0.
(6) Reactor Core Isolation Cooling System Weld No. E51-2192-5WO.
It was determined that (1) weld surface finish and appearance were acceptable and there was not evidence of wall thinning due to grinding; (2) are strikes and weld spatter were not evident and (3) weld crown reinforcement appeared to exceed code requirements on weld No. E11-2327-0W2. The inspector stated this matter is considered unresolved pending a review of the measurement during a subsequent inspection. (341/79-20-01)
No items of noncompliance or deviations were identified.

Observation of Work - While observing welding activities for item stated in paragraph 3 of this report, the inspector determined that preheat met the welding procedure requirements.
' No items of noncompliance or deviations were identified.
i._ Review of Piping Storage Inspection Records The inspecto-reviewed piping storage inspections record for inspection performed on January 24, 1979. The records indicated deficiencies were identified and corrected on July 25, 1979. It was also determined that inspection records for the period between November 1977 and January 1979.ould not be found. This deficiency was identified by Detroit Edison Company QA surveillance report.
No items of noncompliance or deviations were identified.

Safety Related Piping - Welder Qualifications The inspector reviewed the following documents: a.
W & B procedure No. VB-E-118, Revision 6 has not been ' revised since the last review.
, !- 4 * b.
Qualification record of welders with 1.D No. 6RR and 4S who , .f performed weld repairs on welds identified in paragraph 8 of this report.
The inspector determined that the above documents met the re-quirements of ASME B & PV Code Section IX.
No items of noncompliance or deviations were identified.
paresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of non-compliance or deviations. An unresolved items disclosed during the inspection are discussed in Paragraph 4.
Exit Interview The inspector met with the licensee representatives (denoted in the Persons Contacted paragraph) on September 21, 1979. The inspector summarized the scope and findings of the inspection. The inspector further stated that an attempt was made to review W & B weld data sheets. It was determined that (1) final QA review of weld data sheet has not been performed for welds that were accepted by NDE more than a year ago, (2) sign off copies of weld data sheets were missing for some welds and (3) NDE remains to be performed for welds completed over six months ago. Although the examples cited above were identified as items to be performed by W & B, it is felt that a core timely manner to complete some of th, items may be in order.
The licensee acknowledged the information.
