1/4.4.1 RECIRCULATION SYS"IM FC :RCULATION LOOPS M TING CONDITION FOR OPERATION 3.4.1.1 Two reactor coolant system recirculation loops shall be in operation.
APPLICABILITY: OPERATIONAL CONDITIONS 1 and 2*.
EllQt[:
With one reactor coolant system recirculation loop not in operation:
a.
1.
Within 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />s:
a)
Place the individual recirculation pump flow controller for the operating recirculation pump in the Manual mode.
b) Reduce THERMAL POWER to less than or equal to 67.2% of RATED THERMAL POWER.
c) Limit the speed of the operating recirculation pump to less than or equal to 75% of rated pump speed.
d)
Increase the MINIMUM CRITICAL POWER RATIO (MCPR) Safety Limit to the value for single loop operation required by Specification 2.1.2.
e) Change the Average Power Range Monitor (APRM) Simulated Thermal Power - Upscale Flow Biased Scram and Rod Block Trip Setpoints and Allowable Values to those applicable for single recirculation loop operation per Specifications 2.2.1 and 3.3.6.
l f)
Perform Surveille.nce Requirement 4.4.1.1.4 if THERMAL POWER is 1ess than or equal to 30% of RATED THERMAL POWER or the i
recirculation loop flow in the operating loop is less than or equal to 50% of rated loop flow.
2.
Otherwise, be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
