NUCLEAR PLANT NO. 2 OPERATING LICENSE NPF"21 WNP-2 EQUIPMENT SETPOINT METHODOLOGY PROGRAM PLAN At the request of C. J. Bosted, Resident Inspector, attached hereto is the pro-posed WNP-2 Equipment Setpoint Methodology Program Plan. The Supply System has been working on this plan for several months. The methodology was originally targeted to be complete in draft form by April 1989, but was delayed in order to allow consideration of recently published ISA-RP67.04, Part II draft (4/ll/89).

The proposed program is very manpower intensive, and will probably require the par ticipation and support of the Supply System's Technical Support Services Contractor. That Contractor is scheduled to be selected and functional the first quarter of CY 1990. As the program is evolving and based on a draft ISA standard, we anticipate that changes will become necessary as information is gained. The dates included herein are tentative and will have to be adjusted to also reflect manpower avai 1 abi 1 i ty.

The Supply System requests that the NRC communicate any questions and/or concerns they may have as soon as practicable.

MNP-2 EQUIPMENT SETPOINT METHODOLOGY PROGRAM PLAN

1.0 BACKGROUND

During the SSFI audit conducted in August 1987, NRC reviewers identified that existing WNP-2 setpoint methodology did not include consideration of service environment (normal and accident) effects on instrument setpoint accuracies. The Supply System acknowledged this fact but indicated that calculational conservatism offset any effects of environment. Additional-ly, preliminary investigations concluded that many safety related instruments accomplished their intended safety function prior to being affected by abnormal environments.

The Supply System had previously submitted the WNP-2 setpoint methodology to the NRC in May 1985 (Docket Lett'er G02-85-238) and requested in August, 1987 that the NRC approve that methodology. The NRC responded with an SER in November 1988 providing acceptance 'of the WNP-2 'methodology recognizing that it did not yet include environmental/seismic influence criteria. This methodology will become the basis for all WNP-2 setpoint calculations along with new guidance provided by ISA.

2.0 SCOPE The setpoint program shall'ddress and resolve the following issues:

2.1 E ui ment to be Included in the Pro ram The program shall address the following equipment types:

a. Instrumentation to include mechanical switches, electronic switches, analog control setpoints and analog transducers.

b. Electrical equipment to include time delay relays, solid state undervoltage relays and limit/position switches not within the NOVATS program scope.

Mechanical equipment, including relief valves, is not within this program scope.

2.2 Safet Related Yersus Non-Safet Related E ui ment The program shall address all safety related equipment requiring setpoints irrespective of whether that equipment is identified specifically in the Technical Specifications or not. Additionally, non-safety related equipment actuating annunciators which require the Operators to enter into or control within an Emergency Procedure shall also be included within the setpoint program. Although not required, other non-safety related equipment may also benefit from implementation of the program methodology.

2.3 Environmental/Seismic Effects on E ui ment Set pints The program shall provide the meth'odology and application of that methodology for adjustment of equipment setpoints to include effects of environment/seismic resultant inaccuracies.

2.4 Safet Function Com letion Time To minimize the necessity for field setpoint adjustment, the program shall include analysis taking credit for equipment safety function completion time and its relation to the time at which environment/seismic effects "become affecting. This may reduce the number of existing setpoints requiring change'.

2.5 Set oint Calculation Consolidation The program shall addres~ nsolidation of Plant Technical ISCR's and Engineerl'ng calculations into a single calculation per EPN.

2.6 Current Industr Practice The program shall address current industry/ISA methodology and investigate application to WNP-2.

3.0 PROGRAM MILESTONE ELEMENTS 3.1 Industry Methods Investigation 3.2 Formulation of WNP-2 Methodology 3.3 NRC staff approval (verbal approval is sufficient) 3.4 List of equipment requiring setpoint calculations, by EPN, including-analysis to reduce list, where possible by identifying that equipment

.which performs its safety function prior to effects of environmental conditions.

3.5 Determine environmental and seismic accuracy effects for each EPN.

3.6 Determine if qualification tests are required for equipment without required environmental or seismic accuracy data.

3.7 Consolidate Setpoint Calculations 3.8 Provide Setpoint Calculations 3.9 Recalibration of Equipment
