Licensee Action on Previous Inspection Findings,

(Closed) Noncompliance Item (454/79-02-02; 455/79-02-01) - Control ofwelding material: The inspector reviewed the randomly selected weldmaterial issuance slips and determined that returned unused materialswer' marked on the slips.

(Closed) Unresolved Item (454/79-12-01; 455/79-12-01) - Pipe storage: Theinspector reviewed the pipe storage surveillance report which indicatedthat the storage conditions were corrected.

(Closed) Noncompliance Item (454/79-12-01) - Weld data sheet hold point:The inspector reviewed the nonconformance report and determined it wasproperly closed.

(Closed) Noncompliance Item (454/79-12-03; 455/79-12-02) - Control ofDocument: The inspector verified that the procedure supplements havebeen redistributed. The revised procedure was also reviewed.

Functional or Program Areas Inspected

1. Peactor Coolant Pressure Boundary Piping - Observation ofWork and Work Activities (Unit 1)

The inspector observed weld end preparation of Safety InjectionSystem weld No. 122 on Isometric Drawing No. SI-6 and Spool No. SI-1

on Isometric Drawing No. SI-1-4. It was determined that work activitieswere performed in accordance with the applicable procedures and gooda

construction practices were adhered to.

No items of noncompliance or deviations were identified.

2. Reactor Coolant Pressure Boundary Piping - Review of Quality Records

The inspector reviewed the Westinghouse Corporation Qualitya.Release, ASME data Report and Receiving Inspection Report forthe following piping spools:

(1) QR No. 35627 for spool No. CBE-Loop-1-6



(4) QR No. 31246 for spool No. CAE-Loop-2-1

(5) QR No. 31244 for spool No. CAE-Loop-3 f



(8) QR No. 35635 for spool No. CBE-Loop-4-6-

It was determined that the documents are legible and acceptable.

b. The inspector reviewed the pipe storage inspection records forthe period between February 1978, and August 1979. It wasdetermined that (1) the records are difficult to retrieve; (2)inspection was performed at the required frequency and (3)storage requirements were met.

The inspector reviewed the following CECO audit reports:c.

(1) CECO Audit Reports No. 6-79-201, No. 6-79-215, No. 6-79-180and No. 6-78-160.

(2) CECO reports of audit performed at Westinghouse Corporation,Monroeville for years 1977, 1978.

It was determined that the records are acceptable and findingswere closed out in a timely manner. However, the audits atWestinghouse were performed by CECO home office personnel hencenot all the supporting documents, such as follow-up actions,checklists used during the audits, were available on site. Thelicensee stated those documents can be made available, includingthe 1979 audit report, on site. This matter is considered unre-

solved pending a review during a subsequent inspection.(454/79-16-01)>


3. Reactor Coolant Pressure Boundary Piping - Observation ofWelding Activities (Unit 1)

The inspector observed the followlag welding activities:a.

(1) Reactor Coolant System, Weld No. 219 on isometric drawingNo. RC-1-1, Welds No. 82 and 83 on isometric drawingNo. RC-1

(2) Safety Injection System, Weld No. 109 on isometric drawingNo. SI-1.

It was determined that (1) work was conducted in accordincewith traveler; (2) proper welding materials were used; (3)welding procedure requirements were met; (4) work area was freeof welding rod-stubs; (5) physical appearance was acceptableand (6) weld end detail for weld No. 219 on isometric drawingNo. RC-1-1 was not specified and accepted by QC inspector basedon no acceptance criteria. This condition is an item of noncom-pliance identified in Appendix A. (454/79-16-02)

b. The inspector observed liquid penetrant examination of Safety.

Injection System, Weld No. 141 on isometric drawing No. SI-5and weld No. 111 on isometric drawing No. SI-1. It was determinedthat: (1) surface condition was acceptable; (2) procedurerequirements were met and (3) personnel were properly qualified.

Except as noted, no items of noncompliance or deviations were identified.

4. Reactor Coolant Pressure Boundary and Safety Related Piping -Welding Material Control (Units 1 and 2)

a. Review of Documents

(1) The inspector established that Hunter Corporation procedurefor welding material control has not been revised sincethe last review (IE inspection Reports No. 50-454/79-12and No. 50-455/79-12, paragraph 3a) except procedureNo. 5.101. The current revision of this procedure isrevision 6. The revision was reviewed.

(2) Receiving Inspection Report, Material Certification andPurchase Order for ER 308L welding rod with heats No. 741403and No. 741573 and ERNicr-3 welding rod with heats No. 762453and No. 760460.
