Subject:

Request for Additional Information Regarding the Air Quality Standard for the Service Air System Changed in FSAR Amendments 17/18 - Perry Nuclear Power Plant (Units 1 and 2)

On the basis of its review of FSAR Amendment 17 ard 18, the staff has identified the need for the enclosed additional information. The information required con-cerns the basis upon which the air quality standard for the service air systems has been changed from 3 to 40 microns for maximum allowable particle size.

Please advise the Perry Project Manager when we may expect to receive your reply within 5 days after receipt of this letter.

Sincerely, B. J. Youngblood, Chief Licensing Branch No. 1 Division of Licensing

ENCLOSURE AUXILIARY SYSTEMS BRANCH REQUEST FOR ADDITIONAL INFORMATION PERRY NUCLEAR POWER PLANTS, UNITS 1 AND 2 DOCKET NOS. 50-440 AND 50-441 Process Auxiliaries- Compressed Air Systems 1.

FSAR Section 9.3.1, as revised per previous amendment (s) issued, including Amendment 17 and FSAR Section 6.8.4, as revised under Amendment 18 states the following:

,. a.

"The system meets the design guidelines of ANSI Standard MC-11-1 (ISA-S7.3) with the exception that the maximum allowable particle size for air to safety related equipment is 40 microns."

b.

"During operation, instrument air quality will be tested, on an annual basis, at the filter discharge for dewpoint and particulate contamina-tion. The required air quality to safety related components supplied from this system is: zero particulates larger than 40 microns, dewpoint less than '40'F. On failure to meet acceptable air quality, branch lines will be tested to determine the extent of the problem and corrective action needed."

c.

" Air quality will be tested on a yearly basis downstream of the purifier

-e

, package for dewpoint and particulate contamination. The required air

' quality to safety-related components supplied from this system is: zero particulates larger than 40 microns and a dewpoint less than ~40*F."

In order for us to evaluate these statements provide the following information:

1.

Provide the basis for your system design deviation from three(3) micron ANSI, MC-11-1 limit to 40 microns proposed limit for the air quality.

2 b.

Provide verification that the involved safety related equipment will perform its intended functions utilizing the proposed 40 microns .

instrument air quality. , Provide listing of the safety related equipment and corresponding manufacture.'s recommended air quality.

c.

Verify that the air quality, at the _ INLET of the involve safety related equipment, will meet the proposed 40 micron limit in order to perform its intended function. Provide procedures and/or

~

technical specifications to test, detect, and correct the degradation of the proposed instrument air quality at the INLET of the involved safety related equipment in order to assure its

_ intended operation.
