Licensee Action on Previous Inspection Findings a.

(Closed) Deficiency 50-327/78-27-01 and 50-328/78-21-01, Corporate audit documentation.

The inspectors reviewed the OEDC Audit report 79-4 of the organiza-tion, QA progra.a, and the audit program of the Division of Construc-tion for all projects (except Browns Ferry, the only project not under construction). The audit was conducted from March 26 through May 1, 1979 (reference Region II reports 50-327/79-20 and 50-328/79-11). The audit identified two deficiencies relative to training records and

.

.

procedural inconsistancies, neither finding related to the Sequoyah proj ect. The auditors' evaluation was that the effectiveness of the elements of the QA program audited are adequate with the exception of the above two deficiencies.

b.

(Closed) Infraction 50-328/79-04-01, Failure to follow procedure for handling and protection of stainless steel piping.

The inspector reviewed the TVA response to Region II dated April 9, 1979 and the corrective action program as reported in Region II report 50-328/78-16. On this inspection the inspector reviewed the documen-tation of the unscheduled QC inspections of May 9, 16 and 23 and of June 2 of the storage and handling of core spray and residual heat removal piping for Unit 2.

The inspector reviewed the projects standard operating procedure (SOP)

numbered 318 entitled " Resolving and Documenting Items Identified in NRC Exit Meetings or Inspection Reports," revision 0 dated June 11, 1979.

S0P 318 provides for routine inspections of the corrective actions taken by TVA in response to noncompliances and other deficien-cies cited by NRC. The inspections are expected to utilize existing inspection procedures, instructions and records, but are expected to be performed while the corrective action is being implementd for each noncompliance or other deficiency.

Independent Inspection The inspectors conducted a walk through inspection of Units 1 and 2 Containment Buildings and the Auxiliary Building.

Welding of safety injection system piping in the Unit 2 Containment Building was the major safety related construction activity in progress.

The inspectors observed welding of a 2 inch, class A pipe weld in the safety injection system (weld #01988). The applicable weld procedure was GT-88-01, Revision 5.

The qualification of the welder to this procedure was verified. The welding was conducted in accordance with the above weld procedure by qualified welding personnel. The certified material test report for the ER308 Jiller material heat number 462317 being used in the weld was reviewed to determine conformance to the chemical requirements of SFA5.9 of Section II, Part C of the ASME Code. The certified material test report met the chemical requirements specified above.

No items of noncompliance or deviations were identified.
