Subject:

Development of Risk-Based Inspection Guide - Brunswick Steam Electric Plant, Units 1 and 2

!~ The NRC has a program for producing plant-specific inspection guidance for lant's Probabilistic resident inspectors,)

Risk Assessment (PRA . utilizing The the Risk-Based risk insights Inspection from Guide a p(RIG) for a particular plant contains information about its dominant accident sequences, the importance of the various plant systems that contribute to these accident sequences, and the more risk-significant failure modes of the important systems. Any platit-specific vulnerabilities are highlighted for the resident. In addition, inspection checklists are provided for the most risk-significant failure modes.

In order to produce a RIG for Brunswick, we will need the following in1ormation to supplement what we have in your PRA:

1

1. Indexes for normal, abnormal and emergency operating procedures.
2. Mode 1 normal operating procedures, abnormal operating procedures and

- emergency operating procedures for the systems listed in Attachment A.

3. If not included in the normal operating procedures, the Mode 1 system line-up checklists for systems listed in Attachment A.
4. System descriptions (typically from operator training materials) for systems 15,16,17, and 18 on Attachment A.
5. 11" x 17" piping and instrument diagrams listed in Attachment B.
