1 GUIDANCE FOR THE PREPARATION
 
OF A LICENSE AMENDMENT
This extension facilitates the scheduling of surveillance activities and allows surveillances to be postponed when plant conditions are not suitable for con- ducting a surveillance, for example, under transient conditions or other ongo- ing surveillance or maintenance activities. Specification 4.0.2 also limits extending surveillances so that the combined time interval for any three con- secutive surveillance intervals shall not exceed 3.25 times the specified sur- veillance interval. The intent of the 3.25 limit is to preclude routine use of the provision for extending a surveillance interval by 25 percent.
REQUEST TO REMOVE THE 3.25 LIMIT ON EXTENDING
 
SURVEILLANCE
Commmonwealth Edison Company (CECo) submitted a lead-plant proposal for the LaSalle Technical Specifications (TS) to remove the 3.25 limit for surveil- lances that are performed during a refueling outage and are specified with an
INTERVALS
18-month surveillance interval. After discussions with the staff, CECo amended the proposal to remove the 3.25 limitation for all surveillances. The amended proposal was approved by the staff on a lead-plant basis. Consistent with NRC
policy, this Generic Letter provides guidance for license amendment requests to implement this line-item improvement in TS.


==BACKGROUND==
DISCUSSION                    _  _
Specification
Experience has shown that the 18-month surveillance interval, with the provi- sion to extend it by 25 percent, is usually sufficient to accommodate normal variations in the length of a fuel cycle. However, the NRC staff has routinely granted requests for one-time exceptions to the 3.25 limit on extending refuel- ing surveillances because the risk to safety is low in contrast to the alter- native of a forced shutdown to perform these surveillances. Therefore, the 3.25 limitation on extending surveillances has not been a practical limit on the use of the 25-percent allowance for extending surveillances that are performed on a refueling outage basis.
4.0.2 of the Standard Technical Specifications permits surveil-lance intervals to be extended up to 25 percent of the specified interval.This extension facilitates the scheduling of surveillance activities and allows surveillances to be postponed when plant conditions are not suitable for con-ducting a surveillance, for example, under transient conditions or other ongo-ing surveillance or maintenance activities.


Specification
The use of the allowance to extend surveillance intervals by 25 percent can also result in a significant safety benefit for surveillances that are perform- ed on 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 surveillance. Examples of this include transient plant operating conditions or conditions in which safety systems are out of ser- vice 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 surveillance interval would outweigh any benefit derived by limiting three con- secutive surveillance intervals to the 3.25 limit. Also, there is the adminis- trative burden associated with tracking the use of the 25-percent allowance to ensure compliance with the 3.25 limit. On the basis of these considerations, the staff concluded that removal of the 3.25 limit will have an overall positive impact on safety.
4.0.2 also limits extending surveillances so that the combined time interval for any three con-secutive surveillance intervals shall not exceed 3.25 times the specified sur-veillance interval.


The intent of the 3.25 limit is to preclude routine use of the provision for extending a surveillance interval by 25 percent.Commmonwealth Edison Company (CECo) submitted a lead-plant proposal for the LaSalle Technical Specifications (TS) to remove the 3.25 limit for surveil-lances that are performed during a refueling outage and are specified with an 18-month surveillance interval.
An acceptable alternative to the existing requirements of Specification 4.0.2 is the following:

After discussions with the staff, CECo amended the proposal to remove the 3.25 limitation for all surveillances.

Enclosure 1 GUIDANCE FOR THE PREPARATION OF A LICENSE AMENDMENT REQUEST TO

REMOVE THE 3.25 LIMIT ON EXTENDING SURVEILLANCE INTERVALS

BACKGROUND

Specification 4.0.2 of the Standard Technical Specifications permits surveil- lance intervals to be extended up to 25 percent of the specified interval.

This extension facilitates the scheduling of surveillance activities and allows surveillances to be postponed when plant conditions are not suitable for con- ducting a surveillance, for example, under transient conditions or other ongo- ing surveillance or maintenance activities. Specification 4.0.2 also limits extending surveillances so that the combined time interval for any three con- secutive surveillance intervals shall not exceed 3.25 times the specified sur- veillance interval. The intent of the 3.25 limit is to preclude routine use of the provision for extending a surveillance interval by 25 percent.

Commmonwealth Edison Company (CECo) submitted a lead-plant proposal for the LaSalle Technical Specifications (TS) to remove the 3.25 limit for surveil- lances that are performed during a refueling outage and are specified with an

18-month surveillance interval. After discussions with the staff, CECo amended the proposal to remove the 3.25 limitation for all surveillances. The amended proposal was approved by the staff on a lead-plant basis. Consistent with NRC

policy, this Generic Letter provides guidance for license amendment requests to implement this line-item improvement in TS.

DISCUSSION _ _

Experience has shown that the 18-month surveillance interval, with the provi- sion to extend it by 25 percent, is usually sufficient to accommodate normal variations in the length of a fuel cycle. However, the NRC staff has routinely granted requests for one-time exceptions to the 3.25 limit on extending refuel- ing surveillances because the risk to safety is low in contrast to the alter- native of a forced shutdown to perform these surveillances. Therefore, the 3.25 limitation on extending surveillances has not been a practical limit on the use of the 25-percent allowance for extending surveillances that are performed on a refueling outage basis.

The use of the allowance to extend surveillance intervals by 25 percent can also result in a significant safety benefit for surveillances that are perform- ed on 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 surveillance. Examples of this include transient plant operating conditions or conditions in which safety systems are out of ser- vice 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 surveillance interval would outweigh any benefit derived by limiting three con- secutive surveillance intervals to the 3.25 limit. Also, there is the adminis- trative burden associated with tracking the use of the 25-percent allowance to ensure compliance with the 3.25 limit. On the basis of these considerations, the staff concluded that removal of the 3.25 limit will have an overall positive impact on safety.

An acceptable alternative to the existing requirements of Specification 4.0.2 is the following:

SUBJECT: LINE-ITEM IMPROVEMENTS IN TECHNICAL SPECIFICATIONS - REMOVAL OF THE

3.25 LIMIT ON EXTENDING SURVEILLANCE INTERVALS (GENERIC LETTER 89-14)

Specification 4.0.2 of the Standard Technical Specifications allows surveil- lance intervals to be extended up to 25 percent of the time interval specified.

In addition, this specification limits the combined time interval for any three consecutive surveillance intervals to less than 3.25 times the specified sur- veillance interval.

A lead-plant proposal was submitted by Commonwealth Edison for the LaSalle Technical Specifications (TS) to modify the 3.25 limitation on extending sur- veillance intervals. Based on the review of the Commonwealth Edison proposal, the NRC staff concludes that the removal of the 3.25 limit from Specification

4.0.2 results in a greater benefit to safety than limiting the use of the 25- percent allowance to extend surveillance intervals. The enclosed guidance is provided for the preparation of a license amendment request to implement this line-item improvement in TS.

Licensees and applicants are encouraged to propose changes to plant TS that are consistent with the guidance provided in the enclosure. Conforming amendment requests will be expeditiously reviewed by the NRC Project Manager for the facility. Proposed amendments that deviate from this guidance will require a longer, more detailed review. Please contact the Project Manager if you have questions on this matter.

August 21, 1989 MEMORANDUM FOR: All Project Managers FROM: James 6. Partlow Associate Director for Projects Office of Nuclear Reactor Regulation SUBJECT: A LINE-ITEM TECHNICAL SPECIFICATION IMPROVEMENT - REMOVAL OF

3.25 LIMIT ON EXTENDING SURVEILLANCE INTERVALS (GENERIC

LETTER 89-14)

Enclosed is Generic Letter 89-14 which is being sent to all power reactor licensees and applicants. It provides guidance for the preparation of a license amendment request to implement a line-item improvement in Technical Specifications (TS) to remove the 3.25 limit on extending surveillance inter- vals. Any request for this change in TS is voluntary.

It is intended that Project Managers will review and process proposed amend- ments conforming to the guidance of the Generic Letter. Generally, it should not be necessary to consult or to obtain review assistance from the Technical Specifications Branch unless the proposed amendment deviates from the Generic Letter guidance.

Enclosed is a model Safety Evaluation Report (SER) that was prepared by the Technical Specifications Branch. This model SER should facilitate your prepara- tion of a license amendment to implement the line-item improvement in TS.

If you should have any questions on the Generic Letter or model SER, contact Tom Dunning, OTSB, on extension 21189. The Lead Project Manager for this task is Harley Silver on extension 21470. Harley will assist you in the preparation of a NSHC prenotice for a proposed amendment conforming to the Generic Letter and he should be included on concurrence for the license amendment package.
