U. S. Nuclear Regulatory Commission ATTN: Document Control Desk l

Washington, DC 20555 i

Joseph M. Farley Nuclear Plant Control Room Emergency Filtration, Penetration Room Filtration, and Contamment Purge Exhaust Filtration Systems Enforcement Discretion Suoolement Ladies and Gentlemen:

The purpose of this letter is to document our phone conversation that took place between SNC and the NRC on March 3,1997, concerning the Notice of Enforcement Discretion (NOED) that you issued on February 26,1997 for Farley Nuclear Plant (FNP). During this phone conversation, Brian Thomas of NRR stated that it was the NRC's intent to require FNP to test the subject IWAC systems to ASME N510,1989 sections 5,8, and 14. The following clarifications were also provided:

)

1. Testing designated as acceptance by ASME N510,1989 would only be required following

)

l major modification or repair.

2. Testing designated as surveillance would be performed as plant procedures are revised and plant conditions allow.

It is FNP's intent to have required surveillance testing, except those items noted in Attachment 1, completed to support implementation of the Technical Specification amendment that was requested on February 24,1997 and referenced in our NOED.

Per your request exceptions taken to the testing requirements of ASME N510,1989 are provided in Attachment 1, along with SNC's technicaljustification. It is FNP's intent to use this table as guidance in our FSAR in accordance with our amendment request. Any future changes to this table will be addressed through the 10CFR 50.59 process. During the phone call you requested that SNC provide the criteria used initially to accept the subject HVAC systems. For Unit I this is Regulatory Guide 1.52, Revision 0 and for Unit 2 Regulatory Guide 1.52, Revision 2.

U. S. Nuclear Regulatory Conunission Page 2 SNC proposes to submit revised HVAC technical specification surveillance requirements by June 1,1997 that will incorporate ASME N510,1989 testing methodology for our remaining HVAC Technical Specification Surveillance requirements as appropriate. Because of FNP system specific design and testing preferences, some exceptions to ASME N5101989 testing requirements will be made. These will be documented in our submittal. provides a list of attendees to the subject phone call. Should you have any questions or comments please contact me.

If there are any questions, please advise.

the same procedure specified for filter banks in para. 8.5.2.1, except that all velocity measurements shall be made in the plane of the face of the air channels, in the center of every open channel and an equal distance away from the adsorbers. For type ill adsorbers, velocity measurements shall be made in the plane of the face of the air channels. These measurements shall be made in centers of equal area that cover the entire open face, not in excess of 12 in. between points on a channel, and an equal distance away from the adsorber.

beds shall be limited to that value specified in the laboratory test (Section 15).

Notes:

(1) Applies only to sections 8.5.1.1 and 8.5.1.2.

(2) The surveillanceflowrate criteria will not be usedfor the marimum housing componentpressure drop test. Maximum housing componentpressure drop airflow is based on system l

Airflow Distribution Through HEPA Filter Banks. The minimum No Yes number of velocity measurements shall be one in the center of each (Not required) filter. All measurements should be made an equal distance away from i

the filters. Velocity measurements should be made downstream of the filters to take advantage of the airflow distribution dampening effects of the HEPA filters.

Airflow Distribution Through Adsorber Banks. For banks containing No Yes Type I adsorbers, the air distribution test shall follow the same (Not required) procedures specified for HEPA filter banks in para. 8.5.2.1.

that all velocity measurements shall be made in the plane of the face of the air channels, in the center of every open channel and an equal l

distance away from the adsorbers. For type Ill adsorbers, velocity measurements shall be made in the plane of the face of the air channels.

Maximum housing component pressure drop airflows shall be i 10% of the value specified in the test program or project specifications with the pressure drop greater than or equal to the maximum housing component pressure drop. For systems with carbon adsorbers, the maximum velocity of air through the carbon j

beds shall be limited to that value specified in the laboratory test (Section 15).

Notes:

(1) Applies only to sections 8.5.1.1 and 8.5.1.2.

(2) The surveillanceflowrate criteria willnot be usedfor the maximum housing componentpressure drop test. Maximum housing component pressure drop airflow is based on system functionalrequirements.
