NOTICE OF VIOLATION Duke Energy Corporation Docket No. 50-370 McGuire Nuclear Station License No. NPF-17 During an NRC inspection conducted between July 12 and August 22. 1998, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedures for NRC Enforcement Actions." (NUREG-1600) the violation is listed below:

.and venting the emergency core cooling system (ECCS) are included in Appendix A.

Operation Management Procedure (OMP) 7-1. Removal and Restoration (R&R)

Requirements, requires, in part that when designating vent valves for filling and venting, consider the all system high points are vented. physical layout of piping to ensure Technical Specification Surveillance Requirement (TSSR) 4.5.2.b.1.

requires, in part, that each ECCS subsystem shall be demonstrated operable, at least once per 31 days by verifying that the-ECCS piping is full of water by venting the ECCS pump casings and accessible discharge piping high points, unless the pumps and associated piping are in service or have been in service within 31 days.

Implementation of TSSR 4.5.2.b.1 is accomplished by McGuire procedure PT/2/A/4200/019. Revision 12. Unit 2 ECCS Pumps and Piping Vent.

Contrary to the above:

1. On or before December 17. 1997. during restoration of the Unit 2 ECCS subsystems following maintenance on valve 2NI-136B, operations personnel failed to designate the appropriate vent valves for venting to properl., return the system to service as required by OMP 7-1. Specifically, high point vent valve 2ND-77 was not designated following drain and refill of its associated segment of ECCS aiping. As a result, an undetected. volume of gas was left in the ECCS piping.

j - -

-2. Procedure PT/2/A/4200/019. Revision 12. Unit 2 ECCS Pumps and Piping Vent. was inadequate to ensure that the ECCS pi 31ng was full of water during monthly system venting performed Jetween December 17. 1997, and June 5. 1998. Specifically, accessible discharge piping high point vent 2ND-77 was not included in the 9810060265 980921 ,
