0C12 2 N Mr. Alex Marion, Manager Technical Division Nuclear Management and Resources Council 1776 Eye Street, NW - Suite 300 Washington, DC 20006-3706
Dear Mr. Marion:
As you are aware, Brookhaven National Laboratory is currently performing aging assessment of Reactor Core Isolation Cooling (RCIC) system. Information regarding inspection, monitoring, and current maintenance practices will be extremely useful for achieving the goals of Nuclear Plant Aging Reserach (NPAR) program.
Enclosed is a copy of survey for BWR plants-with RtIC systems.
There are RCIC systems on all BWRs except for Big Rock Point, Oyster Creek, Nine Mile Point 1, and Dresden 2 and 3.
I will appreciate it if you would forward the enclosed survey to appropriate nuclear utilities. The completed survey forms will be most useful if returned by February 1,1993.
I appreciate your continued interest and participation in NPAR program.
Sincerely, Original signed by Satish K. Aggarwal Satish K. Aggarwal, Program Manager Electrical & Mechanical Engineering Branch Office of Nuclear Regulatory Research

NUCLEAR PLANT AGING RESEARCH (NPAR} SURVEY REACTOR CORE ISOLATION COOLING SYSTEMS This is a curvey of the monitoring, testing and maintenance practicca used to aneure operational readiness of the Reactor Core Isolation Cooling (RCIC) systems of boiling water reactors (BWRe).
The information you provide will be used to identify methods of detecting and mitigating the ef fects of aging degradation on the systems. Please answer all questions in each section that applies to your plant.
If differences exist in the responses for each unit, please respond on a separate form for each unit.
