UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 nocket No. 50-311 Mr. Steven E. Miltenberger Vice President and Chief Nuclear
- Officer Public Service Electric and Gas Company Post Office Box 236 Hancocks Bridge, New Jersey 08038
Dear Mr. Miltenberger:
January 18, 1989
SUBJECT:
DEVELOPMENT OF A RISK-BASED INSPECTION GUIDE FOR SALEM UNIT 2 The NRC has a program for producing plant-specific inspection guidance for resident inspectors using insights from probabilistic risk assessments (PRAs'.
The Risk-Based Inspection Guide (RIG) for a particular plant contains information about its dominant accident sequences, the relative importance of.
the various plant systems that contribute to these sequences, and the more risk-significant failure modes of the important systems.
Plant-specific vulnerabil;ties are highlighted for the resident inspector.
In addition, inspection checklists are provided for the most risk-significant failure modes.
The purpose of the RIGs is to help focus NRC's inspection activities on the most risk-significant aspects of each plant so that our limited inspection efforts have the most benefit to public health and safety. For example, a RIG directs increased attention to a limited number of plant components and it provides guidance for selecting activities to observe and for events to follow-up.
~'e have developed a methodology to produce RIGs for plants that do not have a PPA.
It uses insi~hts from available PRAs to focus a review of the subject plant's design, technical specifications and operating procedures.
We have found that the resulting RIG can capture a useful portion of the risk-significant features of the subject plant.
The RIG project is not part of the Individual Plant Examinatfon (IPE) program.
When an IPE is completed for your plant, the RIG will be revised as appropriate to include the IPE findings.
In order to produce a-*RIG for Salem Unit 2, we will need some additional information about its design and particularly its operating procedures.
1--'ence, we are asking for your cooperation in pro.vi ding copies of some existing plant documents for this project. Compliance with this request is not required by NRC regulations; we are seekin~ your voluntary cooperation. If you choose to participate with us, WP will make the draft version of the RIG available to you and the resident inspector at your plant so that you can make c011111ents and suggestions before the final version fs COllllJleted.

- The additional information we need to produce the RIG is contained in the following documents:
- 1.
Indexes for nonnal, abnonnal and emergency operating procedures.
- 2.
Mode 1 normal operating procedures, abnonnal operating procedures, and emergency operating procedures for the systems listed in the enclosure.
- 3.
If not included in the normal operating procedures, the Mode 1 system lineup checklists for the systems listed in the enclosure.
- 4.
System descriptions (typically from operator training materials) for systems listed in the enclosure.
- 5.
11" x 17" piping and instrumentation diagrams for the systems listed in the enclosure.
The reporting and/or recording keeping requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.
If you would like to discuss the project or get clarification of any of the requested items, please contact Steve Long at (301) 492-3162.
