NOTICE OF VIOLATION Virginia Electric and Power Company Docket Nos. 50-338, 50-339 j
North Anna Power Station License Nos. NPF-4, NPF-7 During an NRC inspection conducted on January 25-29, 1993, a~ violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed below:
i 10 CFR 50.54(q) states that a licensee authorized to possess and operate-a nuclear power reactor shall follow and maintain in effect an emergency i
plan which meets the standards in 10 CFR 50.47(b) and the requirements of Appendix E to 10 CFR Part 50.
10 CFR 50.47(b)(8) specifies the following emergency planning standard:
" Adequate emergency facilities and equipment to support the emergency j
response are provided and maintained." This standard is met in part by Section 7.1.3 of the Emergency Plan, which states with respect to the Technical Support Center (TSC) that "The construction of the facility i
walls and design of the ventilation system are such that the whole body and thyroid doses received by occupants of the TSC are below GDC -
l
[ General Design Criterion] 19 limits." To meet this goal, a fundamental aspect of the TSC ventilation system design is the provision of positive pressure in all areas of the TSC during operation in the emergency mode.
10 CFR 50.47(b)(8) is also addressed by Section 8.7 of the licensee's Emergency Plan (Revision 14, effective August 31,1992), which states i'
that " Emergency equipment shall be periodically tested to identify and -
correct deficiencies... The testing shall include... every 18 months, functional and performance testing of the TSC... Ventilation system."
The licensee's procedure for functional and performance testing of the i
TSC ventilation system was 1-PT-77.9, "TSC Emergency Ventilation System i
Operability Test," Revision 2, approved July 19, 1989.
l l
Contrary to the above, procedure 1-PT-77.9 was not adequate for identifying and correcting deficiencies in the function and performance of the TSC ventilation system.
The procedure was not designed to 1
identify, as unsatisfactory, a potential condition in which some areas i
of the TSC were not at a positive pressure relative to the facility' i
surroundings when the ventilation system was operating in the emergency
.l mode.
This is a Severity Level IV violation (Supplement VIII).
Pursuant to the provisions of 10 CFR 2.201, Virginia Electric and Power j
Company is hereby required to submit a written statement or explanation to i
the U.S. Nuclear Regulatory Commission, ATTN:
Document Control Desk, j
Washington, D.C. 20555 with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector at the facility that is the subject l
of this Notice, within 30 days of the date of the letter transmitting this I
