Amendment No. 204 Crystal River Unit 3 5.0-23

RCS Pressure, Temperature, and Flow DNB Limits B 3.4.1 BASES APPLICABLE that transients initiated from the limits of this LCO will SAFETY ANALYSES meet the event-specific DNBR acceptance criterion. This is (continued) the acceptance limit for the RCS DNBR parameters. The transients analyzed for include loss of coolant flow events and dropped or stuck control rod events. A key assumption for the analysis of these events is that the core power distribution is within the limits of LCO 3.2.1, "Regulating Rod Insertion Limits," LCO 3.2.2, "APSR Insertion Limits,"

LCO 3.2.3, "AXIAL POWER IMBALANCE OPERATING LIMITS," and LCO 3.2.4, "QUADRANT POWER TILT."

For full power conditions, limits are set on loop parameters to meet the DNBR criterion. The minimum core outlet pressure is the limit value in the reactor coolant loop as measured at the hot leg pressure tap. The maximum hot leg temperature specified is the limit value as measured at the hot leg resistance temperature detector.

The minimum volumetric flow rate corresponds to the mass flow rate for four RCP operation at full power.

Additionally, analyses have been performed to establish the pressure, temperature, and flow rate requirements for three pump operation. The flow limits for three pump operation are approximately 25% lower than the four pump limits. To meet the DNBR criterion, a corresponding maximum power limit of less than the top of the "doghouse" (Power-Imbalance-Flow trip setpoint contained in the COLR) is required in combination with the 3 pump limits (see Bases for LCO 3.3.1, "RPS Instrumentation").

RCS DNB limits satisfy Criterion 2 of the NRC Policy Statement.

LCO Limits on RCS loop (hot leg) pressure, RCS hot leg temperature, and RCS total flow rate ensure that the core (conti nued)
