NRC Dkt. 50-249.
Dear.Mr. Keppler:
In response to subsequent discussi6ns with your* inspector, the Dresden Station refueling interlock.s.urveillance procedure a:qd the.Dresden Station fuel handling procedures have been reviewed.
As a result, the follo\\*1ing further procedu-r:e revisions will be made prior to.the next Unit 2 or Unit 3 re~-q.e,ling outage *
. 1. *Procedure DOS 800-1, "Refueling Interlock Check,; step F. 2.g.,
will be revised.
This rev'isiori will specify a new test weight value *which ensures, regar¢l).ess of*' grapple position, a grapple loaded signal will be present whenever a fuel assembly is on the grapple.
2.
Procedur.es DFP 800-7, "Fuel Handling Inside the Reactor" step
.F.l.i; DFP 800-9, "Fuel Movements From the Spent Fuel Storage Pool to the Reacto:i::" step F.1.1; and DFP 800-10, "Fuel r.fovements
,From,the Reactor to the St0rage Pool" step F.1. h; will be re-
. vised *. These revisions will insert a caution directing the operator not to raise. a fuel assembly if the HOIST LOADED light lails to illuminate.
- This matter is not directly related to the noncompliance i:tem identified in the subject inspection report.
As. described in iefer~~ce (a}, it is our judgemen~ that ~tis not necessary to observe 'the hoist loadcp light. to verify. a*.fuel assemble is "moving.
up" *. This matter concerns the adequacy of the Dresden Station procedures for verification of refueling interlocks.
It is our
