Dear Mr. Jenkins:
In recent years, the United States Nuclear Regulatory Commission (USNRC) has been actively engaged in an effort to improve the ef fectiveness of Technical Specificatisns in controlling nuclear power plant operational risk. Science Applications international Corporation (SAIC) under contract to the NRC. has completed a study of alternative approaches that coJ1d add greater risk per-spective to Technical Specification requirements.
The approach recommended is a real time risk based system for setting Technical Specification requirements.
This approach is based on monitoring the plant operational risk using an inter-active real-time computer program so that the effect of changes to a plant, such as equipment outages, can be assessed in real time and, if appropriate plant activities can be adjusted accordingly, in connection with this program, we are very interested in your efforts in the area of risk based Technical Specifications and would like to propose a technical exchange meeting between our organizations on this subject.
Over the past two years, our contractor. SAIC. has been in touch with Dr. Brian Horne of your staff about risk-based Technical Specifications in general, and the development of the Essential Systems Status Fenitor (ESSM) specifically. Recently. I talked to Dr. Horne about the possibility of a meeting toward the end of October 1988 in England, where we might exchange some ideas and learn core about the results of your activities. Dr. Horne was receptive to the idea and suggested that I contact you to make the arrangements for this visit.
Our primary goal for this meeting is to understand the status of your application of risk based concepts tu Technical Specification requirements, in this regard.
we are very in'? rested in understanding the characteristics of the E55H and would welecme the opportunity to see some actual cases demonstrated. Also, if possible, we would like to discuss the use of the ESSM with some of the plant operations staf f to develop an understanding of how these concepts are being applied.

i in advance of our trip. Mr. David Fischer a Section Chief in the Technical Specifications Branch, will be in England in September.
If convenient. he could meet with you and/or Dr. Horne en September 22 or 23 to provide you with some detail about our ongoing programs. This would also be a good opportunity for Mr. Fischer to receive from you any information or documents related to your program, such as results of the program to far, actual case studies, or user ranuals for ESSH which would help us prepare for a later October meeting.
I would appreciate your thoughts about our suggestion for a meeting in late October as soon as possible and look forward to meeting you.
Sincerely.
