- Crystal River Unit 3. Cycle 9 1.0 Core Operating Limits This Core Operating Limits Report for CR3 Cycle 9 has been prepared in accordance with the requirements of Technical Specification Section 1.1 and 5.6.2.18. The analytical methods used to detennine the core operating limits shall be those previously reviewed and approved by the NRC. These methods are documented in BAW-10179PA. " Safety Critera and Methodology for Acceptable Cycle Reload Analyses", SER dated 3/16/93. Application of the methodology for API and RPI position indication agreement was approved in SER dated June 25,1992.
The following limits are included in this report.
