-BWRFE 1101 Market Street, Chattanooga TN 37402 1 Introduction In anticipation of cycle startup, it is necessary to describe the expected limits of operation.
1.1 Purpose
The primary purpose of this document is to satisfy requirements identified by unit technical specification section 5.6.5. This document may be provided, upon final approval, to the NRC.1.2 Scope This version of the COLR is specifically intended to support the refueling outage. Consequently, this document only covers MODE 5 operation of the unit. Operation outside MODE 5 will be addressed in a future COLR revision.
This document will discuss the following areas:> Shutdown Margin (SDM) Limit (Technical Specification 3.1.1)1.3 Fuel Loading The core will contain all AREVA NP, Inc., ATRIUM-10 fuel. Nuclear fuel types used in the core loading are shown in Table 1.1. The core shuffle and final loading were explicitly evaluated for BOC cold shutdown margin performance as documented in Reference
1.1.4 Acceptability
Limits discussed in this document were generated based on NRC approved methodologies per References 2 through 18.Browns Feny Unit 3 Cyde 16 Page 1 Browns Ferry Unit 3 cyRle 16 Core operating Limits Report, (105% OLTP)Page 1 TVA-C0LR-BF3C16, Revision 0 (Final)

The final composition of the core depends upon uncertainties during the outage such as discovering a failed fuel bundle, or other bundle damage. Minor core loading changes, due to unforeseen events, will conform to the safety and monitoring requirements identified in this document.Browns Feny Unit 3 Cyde 16 Core Operating Limits Report, (105% OLTP)Page 2 TVA-COLR-BF3C16, Revision 0 (Final)
