To assist in your review, Attachments Unit 1 Cycle 12 Core Composition.

Technical Specifications for those Specifications.

D and E have been provided.Attachment D provides the Attachment E provides a cross-reference to applicable references specified in Section 5.6.5 of Technical*'PP&L plans to implement the proposed changes in May 2000 to support the startup of Unit 1 Cycle 12 operation.

Therefore, we request NRC complete its review of this change by February 11, 2000 with the changes effective upon startup following the Unit 1 11~Refueling and Inspection Outage to support our scheduled implementation date.Any questions regarding this request should be directed to.Mr.R.R.Sgarro at (610)774-7552.'ery truly yours, R..By PLA-5040 Document Control Desk copy: NRC Region I Mr.V.Nerses, NRC Sr.Project Manager-QWFN Mr.S.L.Hansell, Acting NRC Sr.Resident Inspector-SSES Mr.D.J.Allard, Pa.DEP 0 l
