Office of Inspection and Enforcenent RII: JPO Region II - Suite 2900 50-321/50-366 101 Marietta Street, IM I&E Inspection Atlanta, Georgia 30303 Report 84-13 ATTENTION: Mr. James P. O'Reilly GENTI2 MEN:
Georgia Power Company provides the following response to a violation identified during an inspection conducted on March 21 - April 20,1984, and reported by your letter dated June 7, 1984 and Report Nos. 50-321/84-13 and 50-366/84-13.
VIOIATION:
T.S.
6.8.1.a requires that written procedures be established, implenented and maintained covering the applicable procedures reccanended in Appendix "A" of Regulatory Guide 1.33, Rev 2.,
February 1978.
Hatch Nuclear Plant procedure HNP-821, Quality Control Work Inspection Progran, paragraph G.l.a (1) requires that inspections be performed on all significant rework and modifications to safety related systems and components to ensure adherence to drawings, specifications and procedures.
10 CPR 50, Appendix B, Criterion V, as implenented in Hatch Unit 2 FSAR Section 17.2.5 requires that activities affecting quality shall be prescribed by doctanented instructions, procedures, or drawings, of a type appropriate to the ciretznstances.
Contrary to the above, on April 27, 1981, work on the High Pressure Coolant Injection Systen minimum flow valve, E41-F012, was performed without adequate documentad instructions, procedures or drawings appropriate to the circtsastances in that the maintenance request ntsnber 1-81-1832 did not prevent nor did inspections detect the installation of short studs which resulted in the improper thread engagenent of four studs which are utilized in attaching the motor operator to the valve.
Consequently, on April 12, 1984, the NRC inspector identified one of the four bolted connections on the minimum flow valve, E41-F012, operator which was not properly fastened (threads galled and stud backed out). Subsequent performance of the surveillance to prove operability denonstrated that the valve, E41-F012, would not stroke.

-July 9, 1984 Page h o Wis is a Severity Invel IV violation (Supplanent I).
RESPONSE 'IO VIOIATION:
A&nission or Denial of Alleged Violation: % e violation occurred.
Reason for the Violation: Review by the Quality Control (QC) Department of maintenance requests concerning ada:Juacy of the work instructions and level of QC inspection was not performed in April 1981 to the detail to which it is currently performed.
QC reviewed Maintenance Request (MR) 1~81-1832 to determine QC involvement in this work activity.
This review shcwed QC participation in what QC considered at the time to be the significant activities of the repair. QC docments show substantial QC activity during valve disassenbly, repair. and reassembly.
MR l-81-1832 was initiated due to failure of' the local leak rate test; therefore, installation of the motor operator was not considered to be as significant as the repair of the valve itself.
Corrective Steps which Have Been -Taken and the Results Achieved:
On April 13, 1984, a cieficiency report (1-84-141) was written on the valve.
On April 15, 1984, the motor operator attachnent to the valve was repaired and successfully stroked per plant procedures. On May 24, 1984, the Maintenance Department replace'd the short studs with studs having adequate thread engagenent and installed locknuts on the gland
' retaining studs.
Corrective Steps Which Will Be Taken to Avoid Further Violations:
It has been and will continue to be the policy of the QC Department to witness significant activities for safety related major maintenance.
'Since the date of this maintenance request, QC has ircreased its inspection of less significant maintenance activities.
Date When Full Canpliance Was Achieved: Full canpliance was achieved on
- May 24,.1984.
