ft1NUTES OF MEETING WITH NUMARC TASK GROUP WHICH IS WRITING NEW STS FOR PLANT SYSTEMS f

On Friday, December 2, 1988, the staff met with the NUMARC task group which is l

writing the'new Standard Technical Specifications (STS) plant system sections to l

hear their early estimate of anticipated technical changes. The staff was also interested in discerning any technical change that might require a review effort outside the normal STS review process.

J

.The task group provided a handout (attached) of several marked up Comt'ustion Engineering Standard Technical Specifications pages and one marked up

.f Comanche Peak-Unit 1 technical specifications page. Some of the marked up pages indicate technical changes to be proposed with the new STS. 'Other marked up pages, however, relate to the task group's ongoing efforts to resolve some of the their own questions.

The following coments relate to the marked up technical specifications pages:

1 LCO 3.7.1.1:

TURBINE CYCLE SAFETY VALVES The task group commented that no accident analysis nor the ASME Code requires more than one code safety valve per steam generator to be operable in MODE 3.

LCO 3.7.3:

COMP 0NENT COOLING WATER SYSTEM The task group would like to add an action statement which allows 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months to repair one train if two trains are inoperable.

The task group commented that with tuo trains of component cooling water inoperable, a plant is required to shutdown; but it it unable to shutdown without cooling. The task group comented that the same situation exists for the service water system.

LCO 3.7.7:

CONTROL ROOM EllERGENCY AIR CLEANUP SYSTEM For MODES 5 and 6, ACTION a., the task group is questioning the bases for placing the operable system in the recirculation mode.

'f The task group will explore the technical bases for the specification and 1,h offer a clarified text.

"ECCS PUMP ROOM EXHAUST AIR CLEANUP SYSTEM e m A..

The-task group would like to add an. action statement.which allows 24-hours to repair'one. train if two trains are inoperable.. They would-like to' add a similar action statement on other similar systems.

d The staff commented that there did not seem to be a clear basis for adding such an additional action-statement.

B.

For Surveillan'ce' Requirement 4.7.8.b.(2), the' task group ' questioned' '

how much painting was incant.by the words, "following; painting."

The task group will explore several technica1' options to clarify the term.

C.

For.. Surveillance Requirement 4.7.8.c., the task group would like to increase the Surveillance Intervals (SI) from 720 hours0.00833 days 0.2 hours 0.00119 weeks 2.7396e-4 months .to 1440 hours0.0167 days 0.4 hours 0.00238 weeks 5.4792e-4 months because'some plants have raported that testing after 720.' hours reveals no problems.

The staff commented that' plants with plant specific supporting data

)

would be allowed'to increase their SI to 1440 hours0.0167 days 0.4 hours 0.00238 weeks 5.4792e-4 months .

~

D.

The ta'sk group would like to relocate Surveillance Requirement 4.7.8.d.

I outside.of. technical specifications.

.The. task' group commented that the filter cooling bypass valves are not -

assumed in any-accident analyses. and,that the valves are not needed-1

.until-after an accident.

y LC0 3.9.12:-

FUEL STORAGE: POOL AIR CLEANUPESYSTEM (Comanche Peak)

The task grou'p proposed a. clarification;to ACTION "a."'

'The task group commented that while.other. proposed' technical changes could develop, the above are the most sig'ific:nt ones known at theitime'of the meeting.

n With respect to situations 6:here proposed technical changesaarefof thb nature'

.of. relocating technical specification requirements outside of. technical specifications, the staff position is presented in the "spl.it report" dated May 9, 1988. The staff does not anticipate revisiting these issues.' 0therwise,

. l i

the staff did not identify any technical change that would require a review H

effortoutsidethenormt.1STSreviewl. process.'
