DUQUESNE LIGHT COMPANY Nuclear Power Division Beaver Valley Power Station, Unit No. 1 Reply to Notice of Violation Combined Inspection Report 50-334/93-01 and 50-412/93-01 Letter dated March 26, 1993 VIOLATION (Severity Level IV; Supplement I)
Description of Violation (50-334/93-01-01)
Technical Specification 6.8.1.9 requires that written procedures be established, implemented and maintained, covering activities listed in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Operating Manual procedure 1.18.4.A,
" Flushing Resin from any Group I Ion Exchanger,"
Issue 2,
Revision 34, specifies that if the level change in the resin waste hold tank (ISW-TK-2), as indicated by level instrument LI-1SW-202, does not agree with the initial resin volume, then the resin transfer shall be repeated.
Contrary to the above, on January 21, 1993, operators flushed resin from deborating demineralizer 1CH-I-3A to the resin waste hold tank with an identified out-of-service resin waste hold tank level instrument (LI-1SW-202) and were unable to verify the level change in the resin waste hold tank.
Reason for the Violation:
The operators failed to properly implement procedure OM 1.18.4.A,
" Flushing Resin From Any Group I
Icn Exchanger to [1SW-TK-2]" by performing a
resin flush with LI-1SW-202 out-of-service.
The operators inappropriately relied on experience with previous resin
- flushes, by observing pump discharge
- pressure, to complete the evolution.
Corrective Action Taken:
The operators involved with the event were counseled on the need for procedure compliance.
The Unit 1
Operating
- Manual, Chapter 18
" Solid Waste Disposal System,"
Section 4 Operating Procedures were reviewed, revised where appropriate, walked
- down, and reissued on April 16, J993.
These procedures now refer to the use of the digital indication on LIS-ISW-202 to determine the level in the resin waste hold tank 1SW-TK-2.
l Maintenance Work Request No. 018321 was initiated on March 3,
- 1993, to have the malfunctioning analog meter LI-1SW-202 permanently l
removed from service.
e-Reply to Notice of Violation Inspect. ion Reports 50-334/93-01 and 50-412/93-01 Page 2 Action Taken to Prevent Recurrence:
The operations personnel involved with solid waste processing attended the refresher training module " Beaver Valley Site Procedure Compliance,"
to re-emphasize the importance of strict procedure compliance.
A Human Performance Enhancement System evaluation was completed on the activities which resulted in this violation.
The circumstances surrounding this violation will be reviewed in the Solid Waste / Process Control Program Module of the Radioactive Waste Shipping and Handling Retraining Course with emphasis on procedure compliance.
Date of Full Compliance:
The station is in full compliance at this time.
The Radioactive Waste Shipping and Handling Retraining Course will be completed by December 15, 1993.
