NOTICE OF VIOLATION Commonwealth Edison Company Docket No. 50-237 Docket No. 50-249 As a result of the inspection conducted on January 7, 1989, through March 17 and April 11, 1989, and in accordance with the General Policy and Procedures for NRC Enforcement Actions, (10 CFR Part 2, Appendix C), the following violations were identified:
- 1.
Dresden Technical Specification 6.2.A requires that plant operating procedures be prepared, approved and adhered to.
DOP 6900-6, 125 Volt DC Ground Detection - Unit 2, Revision 5, requires that while checking for grounds, the control room is to be informed prior to de-energizing each circuit and lists specific circuits that are not to be de-energized.
- 2.
Contrary to the above, on March 4, 1989, an operator did not adhere to DOP 6900-6 by failing to inform the control room prior to de-energizing each circuit and de-energized circuits specifically prohibited by the procedure.
This failure to follow procedure resulted in a Unit 2 reactor scram.
This is a Severity Level V violation (Supplement 1).
Technical Specification 6.2.A states that detailed written procedures covering preventive and corrective maintenance operations which could have an affect on the safety of the facility and testing requirements shall be prepared, approved and adhered to.
Contrary to the above, two rod control charging water check valves were inoperable (internal ball checks were missing) because of inadequate maintenanc~ procedures and were not detected because of the lack of
.prepared, approved testing procedures.
These valves appeared to have been inoperable since August 1986.
This is a Severity Level.IV violation (Supplement I).
The inspection showed that action had been taken to correct the identified violations and to prevent recurrence.
Consequently, no reply to the violations are required and we have no further questions regarding these matters.
