Inservice Testing Program (Plan) For Pumps And Valves l
Revision 3. Change 11 l
l Please find attached Revision 3, Change 11 of the Inservice Testing Program (Plan) for pumps and valves, Change 11 to the Inservice Testing (IST) Plan is being sent to confirm actions taken by Detroit Edison in response to the Safety Evaluation issued f
on May 2,1996 (Reference 4).
/
The Safety Evaluation, references two items which required further discussion
-(
between Detroit Edison and the NRC. The Safety Evaluation stated that Detroit l
Edison should partial-stroke test the Core Spray pump discharge check valves after g
reassembly. These valves are currently in the IST program for disassembly /

l inspection and partial stroke testing. The relief request VR - 45 which was submitted -
l by Reference 3 and evaluated by NRC Safety Evaluation (Reference 4) is for the Core l
l.
Spray pump minimum flow check valves not the Core Spray discharge check valves.
The minimum flow check valves cannot be partial stroke tested due to valve configuration, and the design of the Core Spray system where two pumps are operated in parallel under accident and testing conditions. This discrepancy between i
the Safety Evaluation and Relief Request was discussed during a conference call on i
September 12,1996.
l The Safety Evaluation also stated the current IST program is based on the i
requirements of the 1980 Edition through the winter 1981 addenda of the American i
Society of Mechanical Engineers (ASME) Code. Detroit Edison is currently j
committed to the 1980 Edition through the winter 1980 Addenda of the ASME Code l
as identified in Supplement 4 of the Fermi 2 Safety Evaluation Report. These two items were discussed with Messrs. Colaccino and Kugler of the NRC on September 12,1996.
