Cycle 9 Operaung Umits Report (OLR L This NDIT supersedes NDIT NFS 98.Oll 00. Revision I incorporatet K(Z) and Fxy Radial Peaking Factors into the Section 1.0 desenption of Technical Specificauons affected. Technical Specificanon 4 2.2.2 was added to the title in Section 2.5. Also, Tables I and 2 were revised to add asterisks (*) for denotmg which items were not considered for the surveillance region. Purpose of Inforn.ation: Byron Station is requested to perform an On-Site Review (OSR) of this docunent. Upon completion of the OSR, Hymn Station is to transmit the OLR portion to the Nuclear Regulatory Commission pursuant to Technical Specification 6.9.1.9.
