SUBJECT:

Beaver Valley Power Station - Unit No. 2 Docket No. 50-412 Environmental Qualification of Safety Related Mechanical Equipment Gentlemen:

Submitted for your review at this time are six (6) copies of the updated Environmental Qualification Progran for Safety Related Mechanical Equipment.

This progran has been performed by Duquesne Light Company (DLC) in response to FSAR Questions 270.2 and 270.3 identified in FSAR Amendment 4 (2NRC-3-096, dated December 2,1983).

The progran as revised contains the following information:

1) Qualification methodology utilized
2) Detailed master listing of equipment included
3) Qualification results It is understood that thre e - items will be chosen by the NRC for detailed revi ew . Extensive back-up documentation and additional information is avail-able in conjunction with the progran and will be transmitted to you for those items selected.

The evaluation's results are now complete and DLC has initiated steps to qualify that equipment which has been identified as not having the ability to withstand the postulated environments (Approximately 5% of equipm. included in the prooran). Equipment items with the EQ status' code of "I" oenoted on this master list are included in this category. This generally indicates that a particular type and/or model number is not well suited for a specific area (i.e., containment) as opposed to the item lacking any subs t ant i al qualification levels.
