INSPECTION REPORT NOS. 50-338/87-12 AND 50-339/87-12
.NRC COMMENT:
~
During the Nuclear Regulatory Commission.(NRC) inspection conducted on May 4 -
8,.18 - 22, and June 3 -
5, 1987, a violation of NRC requirements wag identified.
The violation involved a failure to maintain control of safety related. materials as required by approved site procedures and regulatory
- request.
In-accordance -with the " General. Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2 Appendix C (1986), the l violation is listed belew:
Appendix B,
-Cr'iterion V, as implemented by the Virginia Electric and Power Company QA Topical Report (VEP-1-4A),' requires that the activities.affecting quality shall be prescribed by documented instructions, procedures or drawings of. a type appropriate! to circumstances and shall be accomplished in' accordance with these
. instructions, procedures or drawings.
. Administrative. Procedures ADM-8.0, paragraph requires that.
safety-related ' material stored in a designated " Safety-Related.(SR)
Field Storage Area" if not being worked, fabriacted or installed; also,-
.AUM-9.4 requires that all unused electrodes or bare welding rods,....
-must be returned to the welding foreman.... upon completion of, the ' j ob l
or shift. Strict accountability must be maintained.
-Contrary to the above, on May 20, 1987, control over safety-related materials including welding consummables, was not being maintained in that a substantial amount of unused 308L 3/32 "d,
Heat #C53271 l
stainless steel filler metal wire and three 3/4" d class 1 globe' valves 1
1-SI-189, 1-SI-27 and 1-SI-272 had been left unattended overnight on the ground level inside "C" cubicle, i
{.
This is a Severity Level IV violation (Supplement I) and applies only Unit 1.

RESPONSE
- 1. ' ADMISSION OR DENIAL OF THE ALLEGED VIOLATION:
I The violation is correct as stated.
- 2.. REASON FOR THE VIOLATION:
I The violation was caused by personnel failing to designate or create a Safety Related Field Storage Area for the implementation of Engineering Work Request (EWR)87-365 which replaced drain valves in the Unit.1 safety injection system.
The replacement of the drain valves in the safety injection system.was originally ~ scheduled to be completed within one day.
Since the piping took longer to drain than expected, the job could not be completed within the scheduled timeframe.
The valves and welding material were kept in the basement of the containment for several days, until the piping was completely.
drained, before welding the valves into the safety injection system.
l 3.
CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED:
l At the time the NRC Inspector identified the discrepancy, on May 20, 1987, the installation of the valves was being completed. There was no need to create a Safety Related Field Storage Area at this time. The condition of the welding materials and valves used during the job, even though they were not stored in a Safety Related Field Storage Area, was satisfactory. The bare welding wire (stainless steel wire) was sealed in a bag to prevent corrosion, and the valve assemblies were capped until they were installed.
In addition, the welding materials and valves were inspected by the craft prior to installation and
)
found acceptable for use (i.e.
the materials were not damaged and were traceable to
. ;hase documentation). After the valves were installed, the welds were inspected visually by QC and a dye penetrant test was performed to verify that the welds were acceptable.
The welding foreman and work crew for the job were instructed on the proper storage requirements for category 1 materials that are required at a jobsite.
Welding crews were instructed, on August 11, 1987, on the proper storage requirements of category 1 materials that are required at a jobsite.
The procedural requirements of ADM-8.0, ADM-9.6, and ADM-13.4 were addressed.
I
a l >.
4.
CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS:
The appropriate welding procedures will be revised to require the creation of a Safety Related Field Storage Area if a job is not completed during one shift or if materials will be left unattended.
5.
THE DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED:
The revision to the appropriate welding procedures will be completed by September 30, 1987.
