SUBJECT:

REQUEST FOR ADDITIONAL DOCUMENTATION FOR SAFETY SYSTEM ,

ENGINEERING INSPECTION (SSEI) f

Dear Mr. McElwain:

l On January 8,1999, you provided the NRC with information that was requested of you in our l letter dated December 29,1998. We have reviewed that information and have enclosed a list of the modifications and other engineering work products which will be reviewed during the SSEl.

As outlined in our previous letter, please gather this information and make it available to the l NRC to support a pre-inspection planning site visit by the SSEl team leader during the week of ,

January 19,1999.

The team leader for this inspection is Eric Duncan. He can be reached at (630) 829-9739 if you i have any questions. <

)

l We appreciate your cooperation with this inspection.

Sincerely, Original /s/ R. N. Gardner Ronald N. Gardner, Chit.f Engineering Specialist Bra,r.h 2 Division of Reactor Safety Docket No.: 50-461 License No.: NPF-62 l
