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.
