Dear Mr. Moseley:
This is in response to IE Bulletin No. 76-06 concerning diaphr_agm failures in air operated auxiliary actuators for safety/relief valves.
The following is a list of our actions regarding the specific requirements of IE Bulletin 76-06.
- 1.
The valves to which IE Bulletin 76-06 applies are the pressurizer and steam generator power operated relief valves.
The actuators of these valves have been in-spected and found to have no thermal insulation on them.
- 2.
Procedures for inspection and disassembly of the affected valves will be modified to assure that diaphr_agms have not deteriorat"ed.
These modifi-cations will be completed by September 1; 1976.
- 3.
Information r_egarding diaphragm service and shelf life have.been obtained from the manufacturer.
This information is being factored into station procedures to assure that these limits are not exceeded *
. We will report any unusual findings that result from routine valve actuator maintenance.
Very truly yours, ff:f~~
Vice President-Power Supply and Production Operations*
