Syracuse, New York 13212

SUBJECT:

IMPLEMENTATION OF ALTERNATE ROD INJECTION SYSTEM (ARI) DIVERSITY REQUIREMENTS IN 10 CFR 50.62 (ATWS RULE)

FOR BOILING WATER REACTORS (BWRs)

NINE MILE POINT NUCLEAR STATION, UNIT NOS. I AND 2 (TAC NOS.

67506 AND 66573)

The NRC's Executive Director for Operations (EDO), in a letter dated September 20, 1990 (Enclosure

1) to Mr. George J.

Beck, Chairman of the BWR Owners Group (BWROG), indicated that the staff's position on ARI trip unit (TU) diversity was the proper implementation of the ATWS Rule.

Specifically, the staff's position requires trip units in the ARI to be diverse from the trip units in the reactor trip system (RTS).

Accordingly, the staff requests you to confirm in writing whether your plants comply with the staff's position regarding diversity of TUs between the ARI system and the RTS.

To assist you in making this determina-tion, we are enclosing relevant portions of the staff's submittal to the CRGR (Enclosure

2) and the Minutes of CRGR Meeting No.

189 (Enclosure 3).

In the event that your plants do not conform to the staff's position on this matter, you should negotiate a schedule in accordance with 10 CFR 50.62(d) with your proiect manager.

In his letter to the BWROG, the EDO also indicated that, "it should be recognized, however, that this is a generic position and there could be reason for making exceptions in specific cases;

however, no requests for relief are currently under review.".

Requests for relief from this require-ment should be submitted in accordance with 10 CFR 50. 12.

We request that you respond within 60 days from receipt of this letter. If you have, any questions on this matter, please contact the project manager for your plants.
