Mr. P:t:r Ly:n, Group Vics Presid::nt March 31, 1987 Institute of Nuclear Power Operations 1100 Circle 75 Parkway Suite 1500 Atlanta, Georgia 30339 AE0D/E705
Dear Mr. Lyon:
Subject:
Engineering Evaluation Report--RWCU System Automatic Isolation and Safety Considerations The Office for Analysis and Evaluation of Operational Data (AE00) has completed its engineering evaluation on the reactor water cleanup (RWCU) system automatic isolation events and the safety significance of RWCU system operational problems. The principal operational significance of these events is that operator attention and plant technical resources are diverted from other more important matters for investigating and reporting RWCU system spurious isolation events. Additionally, each time an isolation of the system occurs, plant personnel are exposed to additional radiation in order to investigate the isolation. P We have pulled together and summarized a number of operational improvements suggested by licensees of boiling water reactors that might be beneficial to other licensees in striving for excellence in plant operations as it relates to the RWCU system. These potential improvements include hardware changes as well as procedural modifications, and are summarized in Tables 3 and 4 of the attached report. We believe that the information in the report could be useful to INP0 in its ongoing efforts with licensees to improve plant operations and to maintain radiation exposures of personnel to "as low as reasonably achievable" levels.
If you or your staff have any questions regarding this report, please contact Dr. Neill Thomasson of my staff. Dr. Thomasson can be reached at (301) 492-4431.
Sincerely, onsmusapes my

Mr. Peter Lyon well as procedural modifications, and are summarized in Tables 3 and 4 of the attached report. We believe that the information in the report could be useful to INP0 in its ongoing efforts with licensees to improve plant operations and.
to maintain radiation exposures of personnel to "as low as reasonab achievable" levels.
A copy of the final engineering evaluation report and this le er are being placed in the Public Document Room at 1717 H Street, N.W. W ington, D.C. 20555.
