ABSTRACT This Core Operating Limits Report (COLR) has been prepared in accordance with the requirements of TMI-l Technical Specification 6.9.5. The information in this report was reviewed and approved for use at TMI-l by means of the cycle 7 Reload Design Safety Evaluation TI-135400-005, dated April 6, 1988. The cycle 7 core operating limits were generated using the NRC approved codes and methodologies defined by References 1 through 8. The rod index, axial power imbalance, and quadrant tilt limits were then error adjusted for observability and measurement uncertainties (Refs 4 and 5). These error adjusted alarm I setpoint values are the ones provided in this COLR.
The COLR figures may have three distinctly defined regions:
- 1. Permissible Region
- 2. Restricted Region .,
- 3. Not Allowed Region (Operation in this region is not allowed) f Inadvertent operation within the Restricted Region for a period not exceeding four (4) hours is not considered a violation of a limiting condition for operation. The limiting criteria within the Restricted Region are potential ejected rod worth and ECCS power peaking. Since the probability of these accidents is very low, especially in a four (4) hour time frame, inadvertent operation within the Restricted Region for a period not exceeding four (4) hours is allowed.
