um MEMORANDUM FOR:
M. Rogovin, Chairman NRC TMI Investigative Group
- ROM-Victor Stello, Jr., Director, Office of Inspection and Enforcement
SUBJECT:
DRAFT TEKNEKRON REPORT - ANALYSIS OF THE FIRST 18 MONTHS OF LICENSED OPERATION OF.8ABCOCK & WILCOX PLANTS Teknekron Research, Inc. was requested by the IE staff to perform a study of Operating nuclear power plants with B&W nuclear steam supply systems using heir te:hnique for analyzing causally linked events.
Teknekron perfortred a two anase study using this technique which has been previously reported in NUREG/CR 0110 (Phase I) and NUREG/CR 0979 (Phase II).
The results of Phase I were usec as one of the three trial methods for Licensee Regulatory Performance Evalua. ion (LRPE) attempted by the IE staff in 1977 and 1978.
The most recent Teknekron study, the results of which are summarized in the enclosec report, is a part of a continuing ef fort by the IE staff to develop an effec.ive program for LRPE.
Several approaches to LRPE were attempted previously and the results were made available to the public in November 1978.
At tna; tir:e it was reported that each of the three approaches attempted (statistical treatment of noncompliance history, ratings by regional inspectors, and analysis of causally linked events) had strengths and weaknesses, but no single tethoo was favored by the IE technical staff.
Foilowing the Three Mile Island accident, Teknekron was requested to perform a study of operating reactors with B&W nuclear steam supply systems to determine if any further safety insights could be gained by the analysis of operating ex0erience at these facilities as reported through Licens e Event Reports (LER).
The importance of evaluating operating experience is emphasized as a lesson learned from the Three Mile Island accident.
