SUMMARY
Scope:
An enforcement meeting was held at the Region II Office on March 6,
1987.
The Director, Division of Reactor Projects,
opened the meeting by
stating the issue and concerns of Region II on Inadequate Appendix R Circuit
Analysis for certain high-low pressure interfaces.
He then turned the meeting
over to Duke Power Company (DPC).
The Vice President of Design Engineering
opened the meeting for DPC by briefly discussing the subject areas to be
covered. The areas covered involved valves LP-1 and LP-2 in the Low Pressure
Injection System and valve HP-4 on the outlet from Letdown Cooler B.
The
licensee responded to NRC questions throughout the meeting.
The Director,
Division of Reactor Projects, thanked DPC for the presentation and closed the
meeting.

2. Background
The primary issue for discussion was whether or not the licensee had
performed an adequate Associated Circuit Analysis in accordance with
10 CFR 50.48, Appendix R and associated circuits as defined in Generic
Letter 81-12,
dated February 20,
1981.
Specifically with respect to
valves LP-1 and LP-2 in the Low Pressure Injection System (Decay Heat) and
valve HP-4 in the Letdown Cooling System.
3. Enforcement Meeting
During their presentation, DPC made the following points:
a. Motor Operated Valves (MOV) LP-1 and LP-2.
(1) As a result of NRC's concerns on spurious opening of LP-1 and
LP-2, DPC performed additional analysis for these valves.
(2) DPC concluded that a postulated fire in the west penetration
room would not have an adverse effect on LP-1 and LP-2.
2
b. Letdown MOV HP-4
(1) DPC agreed with NRC's finding that MOV HP-4 could open as a
result of spurious signals.
(2) DPC will reroute cables for HP-4 to correct the problem.
