.e i IJCENSE DOCLBENP INVOINED: Technical Specification RRFIG4S: 4.0.2.b IESCRIPf1W OF REQUESP:

mis subnittal requests the deletion of Specification 4.0.2.b frun Technical Specifications.

REASON RR REQUESff:

Specification 4.0.2 of the Technical Specifications pennits surveillance intervals to be extended up to 25 percent of the specified interval. Eis extension facilitates the scheduling of surveillance activities and allows surveillances to be pc4cred when plant conditions are not suitable for conducting a surveillance, for example, under transient conditions or other ongoing surveillance or maintenarx:e activities. Part b. of this specification

! also limits extending surveillances so that the ccabined time interval for any three consecutive surveillance intervals shall not aw=d_ 3,25 times the specified surveillan interval. We intent of the 3.25 limit is to preclude routine use of the provision for extending a surveillance interval by 25 percent.

In a literal application of Specification 4.0.2.b, time spent in refueling 3 outages is neglected. As a result, normal surveillance intervals end up being l' shortened to ensure ocuplianoe. Refueling interval surveillances, for exanple, l have ended up being reduced from 18 nonths to 12 months. m is was due to the i inclusion, in the surveillance due date calculation, of 6 months worth of L refueling / maintenance outages that occurred within the previous 2 consecutive L test intervals. mis practice has in the past caused Florida Power Corporation and NRC Iesources to be expended on processing requests for one-time exceptions for the performance of affected surveillances. As a result, the deletion of Specification 4.0.2.b is requested. m is is being done in l accordance with NRC Generic letter 89-14 (RemWal of the 3.25 Limit on ll Extending Surveillance Intervals).

EVAURfIW OF REQUESP:

Experience has shown that surveillance intervals, with provisions to extend them by 25 percent are usually sufficient to am--.- -hte normal variations in the length of a fuel cycle. However, tha NRC staff has granted requests for one time exceptions to the 3.25 limit on exterxling refueling surveillances because the risk to safety is low in contrast to the alternative of a forced shutdown to perform these surveillances. %erefore, it has been concluded the 3.25 limitation on extending surveillances is not a practical limit on the use of the 25 percent allowance for extending surveillances that are performed on a refueling outage basis.

We uso of the allowance to extend surveillance intervals by 25 percent can result in a significant safety benefit for surveillances that are performed on

1 a routine basis during plant operation. This safety benefit is incurred when a surveillance interval is extended at a time that conditions are not suitable for performing the surveillanoe. Exanples of this include transient plant operating conditions or ccriditions in which safety systems are out of service because of ongoing surveillance or maintenance activities. In such cases, the safety benefit of allowing the use of the 25 percent allowance to extend a j surveillance interval would outweigh any benefit derived by limiting thme .

consecutive intervals to the 3.25 limit. Additionally, them is the l administrative and logistic burden associated with tracking the use of the 25 I percent allowance to ensure ocmpliance with the 3.25 limit. On the basis of  !

these considerations, it is concluded that removal of the 3.25 limit will have l

an overall positive impact on safety, i SEDILY EVALIDLTIGi:

Florida Ptwer Corporation (FPC) proposes that this change does not involve a significant hazards consideration. 7he de]etion of the 3.25 limit on extending surveillances has no negative inpact on plant operation or safety. The use of the allowance to extend surveillance intervals by 25 percent results in a ,

significant safety benefit when the surveillance is extended at times when conditions are not suitable for performing the surveillance. In these cases, the safety benefit of allowing the use of the 25 percent extension would outweigh any benefit derived by limiting three consecutive intervals to the 3.25 limit.

Based on the above, FPC finds that the charge will not:

1. Involve a significant increase in the probability or consequence of an accident previously evaluated because the deletion of the 3.25 limitation recognizes that the most probable result of any particular surveillance belig performed is the verification of conformance with the Surveillance Requirements. Therefore, accident analysis assunptions reflected in these Surveillance Requirements will still be verified on a frequency sufficient to ensure that the assunptions are reliably maintained.

2. Create the possibility of a new or different kind of accident previously evaluated because the proposed change introduces no new mode of plant operation nor does it require physical modification to the plant.

Additionally, the surveillance interval will still be constrained by the 25 percent extension criteria of Specification 4.0.2.

l 3. Involve a significant reduction in the margin of safety. Any reduction in the margin of safety will be insignificant ard offset by the safety benefit gained by allowirg the surveillance to be extended at times when conditions are not suitable for performirg the surveillance ard by not forcity the plant through a shutdown transient to perform refueling interval surveillances.
