l. INTRODUCTION AND

SUMMARY

This report contains the maximum average planar linear heat generation rate (MAPLHGR) values for the GE fuel design (GEBXSEB bundle type BD321B) to be loaded into Nine Mile Point Nuclear Generating Station Unit 1.

Appendix A contains summaries of MAPLHGR versus exposure for the BD321B fuel bundle. These MAPLHGRs are determined based on the analyses detailed in Reference l.

Appendix B contains a description of the BD321B fuel type.
