SUBJECT:

CERTIFICATE AMENDMENT REQUEST - PADUCAH GASEOUS DIFFUSION PLANT AUTOCLAVE MANUAL ISOLATION SYSTEM (TAC NO. L32003)

Dear Mr. Miller:

This refers to your application dated October 31,1996, requesting an amendment to the Certificate of Compliance for the Paducah Gaseous Diffusion Plant to incorporate a new l Technical Safety Requirement associated with the Autoclave ManualIsolation System.

Our review of your February 14,1997, response to the request for additionalinformation has identified two issues related to Technical Safety Requirement 2.4.4.13 that need to be i resolved before final action can be taken on your request. These issues have been l discussed with Mr. Mark Smith of your staff. Issue 1 concerns ne valves identified in Required Action D.2. It appears that valve XV-511 has been misidentified and should be i valve CV-511. Issue 2 concerns Required Action D.3. As written, the inoperable actuation l davices located in the feed facility could remain in an inoperable state indefinitely. This situation is not acceptable. Required Action D.3 should contain an AND statement that requires operability to be restored within a set timeframe. If operability can not be restored with the set timeframe, Required Actions D.1 or D.2 should be taken. A suggested  ;

timeframe for restoring operability is 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, however, we would consider different times '

to be acceptable with adequate justification. The additionalinformation should be provided within 15 days of this letter. Please reference the above TAC No. in future correspondence related to this request.

If you have any questions regarding this matter, please contact me at (301) 415-8126.
