This letter is to infom the Board of two matters relative to the Three Mile Island Nuclear Station, Unit 2 (TMI-2):

In addition, we enclose fer your information a 10 CFR Part 21 report concerning the cencealmant of three pipe gauges by a qualified welder.

With regTrd to the first matter, on January 13, 1978 the Applicant notified the NRC, Region i Office of Inspection and Enforcement, of a deficiency with the reactor building emergency cooling booster pumps, in accordance with 10 CFR 50.55(e).

building fan coolers, epparently due to an error in procurement.

It was indicated that the replacements necessary for correcting this deficiency will be delivered in several weeks.

Regarding the second matter in section 9.6.2 of the NRC Staff's SER for TM1-2, we stated that each diesel generator is provided with two separate and independent compressed air starting trains each capable c' providing five starts withcut recharcing (totalling ten starts for r aiesel ).

The Applicant recently infor 4d the NRC Staff that the tota number of starts >rovided by the two separate independent starting trains serving each diesel generator is not ten but five without recharging.
