Dr. W. D. Travers Director US Nuclear Regulatory Commission c/o Three Mile Island Nuclear Station Middletown, PA 17057
Dear Dr. Travers:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. DPR-73 Dccket No. 50-320 Inservice Inspection Program Pursuant to the NRC Letter dated June 4, 1986, GPU Nuclear has initiated a formal Inservice Inspection (ISI) Program at TMI-2. As discussed with your staff, the attached list of category B and C valves have been included in the program. All of the valves listed in the attachment have been tested satisfactorily except as noted. GPU Nuclear will continue to perform the ISI program on a quarterly basis, per the requirements of ASME Boiler and Pressure Vessel Code,Section XI, " Rules for Inservice Inspection of Nuclear Power Plant Components", until such time as the GPU Nuclear request for exemption from ISI requirements (reference GPU Nuclear letter 4410-86-L-0075 dated May 15, 1986) is granted.
Sincerely, L
. R. Standerfer Vice President / Director, TMI-2 FRS/CJD/eml y

NOTES:
1.
AH-V-28 A and B cannot be tested at this time due to cooler AH-C-17A being out of service. These valves will be tested once the cooler is l
repaired.
(
2.
NR-V-39A has been tested. NR-V-39B will be tested during the July i
j Monthly Surveillance for Emergency Diesel Genrator 18.
j l
3.
NR-V-181 A and B have replaced NR-V-186 A, B, C and D, which were f
referenced in the GPU Nuclear submittal 4410-86-L-0075 dated May 15, 1986. Valves NR-V-186 A, B, C and D have been removed from the Nuclear l
l Service River Water System.
l 3
i 4.
SW-V-1A cannot be tested because screen wash pump 1A (SW-P-1A) is no 1
longer installed. SW-V-18 cannot be tested because the valve internals i
have been removed. The safety function of this check valve is to open j
upon SW-P-1B startup to permit flow to the screens. Since the valve internals are removed, (i.e., valve is always in the open position), it i
still performs this function.
