f)ARK-II POOL DYNAtlIC LOADS PROGRAM - SUSQUEHANNA STEAtt ELECTRIC STATION, UNITS 1

AND 2

Dear tflr. Curtis:

J J

~ r The thark II lead plant program is essentially complete, and, we are now planning our review of the closure program for the Hark II pool dynamic loads.

A growing tendency of applicants to depend on plant-unique pro-grams, rather than generic programs, during the past year makes it nec-essary'for us'o request definition of 'the pool dynamic loads programs being relied on by each Hark II owner, especially that part which falls outside the scope of the generic Hark II pool dynamic loads progran.

lie have bel.ieved for some time-that joint efforts'toward resolution of issues on a generic basis resu'tts in substantial cost, and schedule savings to the NRC, the industry, and thus to the public.

He stated this view in April 1976 during the early stages of our review of the

'Bark II program, and again in September 1978 when, the t~fark II'lead plant acceptance criteria were issued.

On July 24, 1979 the staff met with

the Hark II owners to discuss the closur'e efforts associated with the Mark II Long Term Program.

At this meeting, the Nark II owners stated that the generic programs associated with SRV and LOCA pool dynamic loads would be completed in 1979 and 1980, respectively.

However, the Hark II owners identified a number of plants requesting relief from the generic pool dynamic loads specifications.

This resulted in a comparable number of new plant-unique programs.

Little information has been pro-vided to the NRC defining these new plant-unique pool dynamic programs.

Considering the design differences between Hark II plants, and. the various licensing schedules for plants, we see a limited need for re-or~/@

our licensing activities for these plants in a timely manner only if the Hark!! owners pursue a generic approach to resolution of pool dynamic load issues to the maximum extent practicable.

For those areas where a completely gener ic approach is not acceptable, we encourage use of semi-generic approaches, as in the case of the lead plant owners and the KTG "T" quencher.

Another posdible sub-grouping would be to combine analyses for plant's with a cordon architect engineer.

'I

>le ask that.you provide a description of those pool dynamic load tasks, outside the generic-Hark!! pool dynamic loads program, thdt are a part of'our pool dynamic loads definition program.

Your response should in-clude the following information task description rationale for plant unique program task schedule documentation (contents and schedul e).

~

.This information should be provided to us by november 15, 1979, so that we can plan our review efforts.

lfe anticipate a meeting to discuss these items at an early date following the submittal of the letters.

The pur-pose of this meeting would be to determine the extent to which a generic

'or semi-generic approach has been pursued, and to obtain information needed by us to establish priorities for the review of the various plants. 'Until thag time, we will continue to review the pool dynamic load program on a primarily generic basis.

We jnten3 to review non-generic pool dynamic load programs on the basis of available NRC resources, with review priorities for these programs established by the licensing schedule for" each facility.
