Functional or Program Areas Inspected 1.
Reactor Coolant Pressure Boundary and Safety Related Piping - Welding Procedures, Specificatiuns, and Quality Assurance Procedures a.
Quality Assurance Procedures The inspector reviewed the Baldwin Associates, Incorporated (BA)
Quality Assurance manual and procedures related to the welding of reactor coolant pressure boundary and safety related piping.
It was established that the manual and the procedures have not been revised since the last review (Report No. 50-461/80-03 ex-cept for four procedures. The revised portion of the four procedures were reviewed and determined to be acceptable.
b.
Welding Procedures The inspector reviewed the following BA welding procedures:
-2-
,
(1) GE/NP-1-1-BA-2L, Revision 2, and Procedure Qualification Record (PQR) Nos. 20 and 21.

(3)
NP-1-1-BA-L, Revision 4, and PQR Nos. 0606, 24, 25 and 26.
(4)
NP-8-8-BA-M, Revision 4, and PQR No. 109-16.
(5)
N-1-1-B-S, Revision 7, and PQR Nos. 6907 and 44.
It was determined that ASME B&PV Code Section IX requirements were met.
No items of noncompliance or deviations were identified.
2.
Reactor Coolant Pressure Boundary and Safety Related Piping - Welding Material Control The inspector reviewed the following documents:
a.
(1) BA procedure No. BTS-402, Revision 14, " Procedure Specification for the Procurement, Storage, and Control of Welding Filler Materials."
(2) BA procedure No. BTS-402 (GE/ Weld Control), Revision 2,
" Procedure Specification for the Procurement, Storage, and Control of Welding Filler Materials."
(3) Receiving Inspection Reports, Material Certifications, and Purchase Orders for ER 309 welding rods with heat No.
C3287T309, No. D3313T309, No. A3287T309, No. 6J12A mix 19, No. 6N22B mix 15, and No. 7A12B mix 9.
It was determined that the above requirements met the PSAR, 10 CFR 50, Appendix B, and the applicable code and procedure requirements.
b.
Control of Materials The inspector toured the welding material issuance station No. 4.
It was determined that (1) the welding materials are properly identified and segregated; (2) the temperature of the rod oven is maintained; (3) records are properly kept; (4) issuance and return of welding materials are controlled in accordance with approval procedures and (5) sandwiches were being stored in a rod oven, No. TS-192. This condition represents an item of noncompliance identified in Appendix A (461/80-07-01).
Except as noted, no items of noncompliance or deviations ;ere identified.

3.
Reactor Coolant Pressure Boundary Piping - Observation of Welding Activities The inspector observed the following activities:
Nuclear Boiler System weld No. B4 on traveller No. IB21-D302B-A-FI.
a.
,
b.
High Pressure Core Spray System weld No. 1-HP-5-9.on traveller No. HP-5-A.
c.
Nuclear Boiler System weld No. C4 on traveller No. 1B21-D302C-A-FI.
d.
Recirculation System weld no. A3 on traveller No. B33-G001-A.
It was determined that (1) work was conducted in accordance with the traveller; (2) proper welding materials were used; (3) welding proce-dure requirements were met; (4) work area was free of weld rod-stubs; (5) physical appearance was acceptable; and (6) the weld bead width of a fill pass on weld No. A3 on traveller No. B33-G001-A exceeded the welding procedure allowance.
This represents a noncompliance as identified in Appendix A (461/80-07-02).
Except as noted, no items of noncompliance or deviations were identified.
4.
Reactor Coolant Pressure Boundary Piping - Observation of NDE Work Activities The inspector observed liquid penetrant examination on the following welds:

Qualification records of twelve welders who performed welding on welds stated in paragraphs 3 and 9 of this report.
The inspector determined that the above documents met the require-ments of ASME B&PV Code Section IX.
No items of noncompliance or deviations were identified.
7.
Reactor Coolant I'ressure Boundary Piping - Special Welding Applications The inspector observed grinding of defects of the Nuclear Boiler System weld No. B4 on traveller No. 1B21-D302B-A-FI.
It was determined that procedure requirements were met and good construction practice was ad-hered to.
No itemt of noncompliance or deviations were identified.
8.

Exit Interview The inspector met with the licensee representatives (denoted under Persons Contacted) at the conclusion of the inspection on April 24, 1980. The in-apector summarized the purpose and findings of the inspection. The inspec-tor again emphasized his concern relative to the monitoring and enforcement of the four hours allowance of electrodes being out of the portable oven as allowed by the weld material control procedure.
It was also noted that about thirty 1/8" diameter and eight 3/32" diameter coated electrodes at one weld joint location were not returned to the portable oven prior to the craftsman going to lunch, and the electrodes were stone cold. This is contrary to a statement made by a licensee representative during an exit interview on March 6,1980, that it is a general practice that electrodes are returned to the portable oven during lunch break. The licensee acknowledged the infor-mation.
