(Closed) Unresolved Item 414/85-43-01: " Fillet Weld Leg Size Joint

  • Geometry Ccnfiguration for (1/6 inch to 3/16 inch gap) Not Considered

! at Final Visual Inspection" The inspector discussed this matter with the licensee, reviewed the AWS D1.1-1980 (Catawba code of record) and AUS D1.1-1985 with commen-tary, reviewed the applicable licensee procedures M-21 and CP-2 Using the AWS D1.1-1985 commentary paragraph C6.5 as guidance to the intent of the AWS Code Committee, the inspector decided that AWS D requires final visual inspection for all welds and inspection at

" suitable intervals" (periodic inspections) to make certain that the requirements of the applicable sections of the AWS D1.1 Code are me Because Duke Procedure M-21 requires periodic inspections of joint fitup, root pass, and assurance that the joint is in accordance with appropriate construction procedures which include the requirements for the fillet weld size when gaps are 1/16 to 3/16 inches, the inspector considers that the licensee's program in this area is consistent with the AWS D1.1-1980 Code inten This matter is considered close . Unresolved Items Unresolved items were not identified during this inspection.

, Independent Inspection Effort Housekeeping (548348), Material Identification and Control (429028) and Material Control (42940B) (Units 1 */ 2)

The inspector conducted a general inspection of the Unit 2 Containment, the auxiliary building and the Unit 2 fuel building to observe such as house-keeping, material identification and control, material control, and storag Within the areas examined, no violations or deviations were identifie . Reactor Vessel Internals (Unit 2)

,

The inspector reviewed procedures, programs, and associated quality records to determine whether quality assurance plans, instructions and procedures for reactor vessel internals installations activities have been established in the facility QA manual; whether these documents conform to the QA program as described in Chapter 17 of the Safety Analysis Reports (SAR); whether activities relative to reactor vessel internals installation had been acc omplished in accordance with NRC requirements and SAR commitments; and whether records reflect work accomplishment consistent with NRC requirements and SAR commitment Review of Quality Assurance Implementing Procedures (50061B)

ihe inspector reviewed selected documents to determine whether i

appropriate and adequate procedures were included or referenced in the QA manual to assure that activities associated with . reactor vessel

(Closed) Item 414/79-02: " Steam Generator Wa.er Level Measurement System Error" (10 CFR 50.55(e))

On August 20, 1979, the licensee notified IE:II of a 50.55(e) item concerning the steam generator water level measurement system errors. The final report was submitted on December 28, 198 The report has been reviewed and determine to be acceptable by IE:I The inspector held discussions with responsible licensee and/or contractor representatives, reviewed supporting documentation, and observed representative samples of work to verify that the corrective actions identified in the report have

been complete '

(Closed) 414-COR-85-34: " Cold Spring of Safety-Related Piping" (10 CFR

'

50.55(e))

On November 8, 1985, the licensee notified IE:II of a 50.55(e) item concerning a section of safety injection system piping which was cold sprung beyond procedural limits. The licensee conducted an investigation, and based on interviews with involved licensee employees, concerns about cold spring were limited to the three cases identified in NCI 19995 and NCI 20004. It is not clear to what extent eitner of the cases actually occurred, but there was enough concern and questions to warrant a full investigation / evaluation. The two 8" lines and the 3" lir.e were analyzed using the largest estimates of the fit-up gaps which were alleged to be cold i sprung beyond procedural limits. The results of the analysis show that each line is adequate as erected. If the cold springing had occurred and had

'

gone undetected, it would not have adversely affected the safety of the system.

After the initial notification and prior to this inspection, the licensee stated that this condition was not considered significant and thus not reportable. This inspector reviewed / inspected the applicable deficiency reports, evaluation and the item in question. Based on the above review and

, inspection, this inspector concurs that the item is not reportabl Within the areas examined, no violations or deviations were identifie . Inspector Followup Items (92701B) (Unit 1)
