Dear Mr. Eisenhut:

Three Mile Island Nuclear Station, Unit 2 (TMI-2)

Operating License No. DPR-73 Docket No. 50-320 Generic Letter 84-15 Attached is TMI-2's response to Generic Letter 84-15, " Proposed Staff Actions to Improve and Maintain Diesel Generator Reliability". Tables 1 and 2 of the Enclosure provide a time history of the last 100 valid starts of each TMI-2 diesel generator.

Sincerely, \

ATTACHMENT (4410-85-L-0140)

NRC Item 1 - Reduction in Number of Cold Fast Start Surveillance Tests for Diesel Generators This item is directed towards reducing the number of cold fast start surveillance tests for diesel generators which the staff has determined results in premature diesel engine degradation. The details relating to this subject are provided in Enclosure 1. Licensees are requested to describe their current programs to avoid cold fast start surveillance testing or their intended actions to reduce cold fast start surveillance testing for diesel generators.

GPU Nuclear Response During the recovery mode, TMI-2 is not required to perform cold fast starts on the emergency diesel generators CF-X-1A and B. The diesel generators are operated and surveilled in accordance with TMI-2 Procedures 4210-0PS-3860.01,

" Emergency Diesels and Auxiliaries", and 4303-M16A/B, " Emergency Diesel Generator Operability Test", respectively. These procedures include the manufacturer's (Fairbanks/ Morse) recommendations for prelubing and warming prior to starting the diesel generators.

NRC Item 2 - Diesel Generator Reliability Data This item requests licensees to furnish the current reliability of each diesel generator at their plant (s), based on surveillance test data. Licensees are requested to provide the following information:

... include the number of failures in the last 20 and 100 valid demands indicating the time history for these failures. Licensees are requested to indicate whether they maintain a record which itemizes the demands and failures experienced by each diesel generator unit, in the manner outlined in Regulatory Guide 1.108 position C.3.a. for each diesel generator unit. Licensees should also indicate whether a yearly data report is maintained for each diesel generator's reliability."

GPU Nuclear Response The reliability of the diesel generators at TMi-2 is shown below:

DIESEL FAILURES IN THE FAILURES IN THE GENERATOR LAST 20 TESTS RELIABILITY LAST 100 TESTS RELIABILITY DF-X-1A 0 1.0 Test Nos. 52 & 74 .98 DF-X-10 0 1.0 Test No. 18 .99 The above figures were derived from the enclosed Tables 1 and 2 which include the last 100 valid starts for each diesel generator. Valid starts were classified in accordance with Regulatory Guide 1.108; invalid tests are marked "NA".

r ATTACHMENT l (4410-O-L-0140)

The information listed in Tables 1 and 2 were obtained from the Control Room Operator's log. This information is also obtainable from the following TMI-2 documents:

l 0 Licensee Event Reports l

l o Technical Specification completed surveillance procedures l 0 Machinery computer history of corrective maintenance, preventive l

maintenance, and test results of the diesel generators TMI-2 does not maintain records of diesel generator operational and failure data as outlined in position C.3.a of Regulatory Guide 1.108. Additionally, TMI-2 does not maintain a yearly data report of each diesel generator's reliability. GPU Nuclear believes, however, that the above listed documents provide an accurate historical account of any events relating to the TMI-2 diesel generators.

l 1

1 NRC Item 3 - Diesel Generator Reliability Licensees are requested to describe their program, if any, for attaining and maintaining a reliability goal for their generators. An example of a l performance Technical Specification to support a desired diesel generator

reliability goal has been provided by the staff in Enclosure 3. Licensees are

! requested to comment on, and compare their existing program or any proposed I program with the example performance specification.

( GPU Nuclear Response i

As indicated in the response to Item 2, the reliability figures for the diesel

! generators indicate that there is currently no need for an improved diesel generator reliability program. Futhermore, the NRC's Amendment Order dated December 19, 1984, reduced the number of surveillance runs from once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to once every 7 days when a redundant diesel generator or offsite power source is out of service. Reducing the frequency of unnecessary diesel generator starts results in improved reliability by decreasing the possibility of premature diesel engine degradation.

GPU Nuclear is currently developing a Technical Specification Cnange Request (TSCR) which proposes deleting the diesel generator requirements at TMI-2.

This proposed TSCR is based on a Safety Evaluation Report which demonstates that the diesel generators are not required for safe operation of TMI-2 during the recovery mode.

Therefore, pending the submittal and approval of the above TSCR, LiPU Nuclear does not intend to alter the surveillance and maintenance programs of the THI-2 diesel generators.
