==Dear Mr. Denton:==

==SUBJECT:==
Grand Gulf Nuclear Station Units 1 and 2 Docket Nos. 50-416 and 50-417 License No. NPF-13 File 0260/M-001.0 ADS Air System, Periodic Air Quality Evaluation AECM-82/528

==References:==
: 1. AECM-82/490, October 18, 1982
: 2. AECM-82/510, October 26, 1982 In accordance with requests by the Auxiliary Systems Branch and the NRC Project Manager for Grand Gulf, Mississippi Power & Light Company (MP&L) is providing additional information to supplement the discussions and commitments in the reference letters. This information is in support of the NRC Staff's review of MP&L's response to NUREG-0737, item II.K.3.28.
: 1. Instrument Air Quality The Grand Gulf instrument air system is not a safety-related system; however, it does supply air to the accumulators of safety related components such as the automatic depressurization system valves.
It is the NRC's position that appropriate air quality is necessary to ensure proper operation of these safety related components. Therefore, consistent with current NRC requirements, MP&L commits to annually sample for instrument air quality commencing at the first refueling outage. The sample will be taken down-stream of the air dryer af terfilters and will be analyzed for dew point, particle size, and oil content. This will ensure that the proper quality air is supplied to the attached safety-related components. Appropriate proposed Technical Specifications with acceptance criteria will be provided to the NRC as discussed below.
Sampling for hazardous gases and corrosive contaminants in accordance with ISA-S7.3-1975 is not considered necessary because:
: a. The instrument air intake is located on a building roof, not inside where it might be exposed to contaminants.
: b. The instrument air system will not be used to supply emergency        'Bo0/
breathing air.
