DESIGNATION P-7 COVDITIOV A'.:D SETPOIVT With 2 of 4 Power Range Neutron Flux Channe ls greater than or equal to 11~ of RATED THER.'LAL POWER or 1 of

> ".urbane First S tage Pressure channels greater than or equal "o 37 psig.

FUNCTION P-7 prevents or defeats the automatic block of reactor trip on:

Low flow in more than one primary coolant loop, reactor coolant pump under-voltage and under-frequency, turbine trip, pressurizer low pressure, and pressurizer high level.

Low flow in a particular loop can be evidenced by either a detected low flow or by the opening of the reactor coolant pump breaker.

P-8 P-10 With 2 of 4 Power Range Neutron Flux channels greater than or equal to 31% of RATED THERMAL POWER.

With 3 of 4 Power Range Neutron Flux channels less than 9% of RATED THERMAL POWER.

P-8 prevents or defeats the automatic block of reactor trip caused by either a low coolant flow condition in a single loop or a reactor coolant pump breaker trip on a single loop.

P-10 prevents or defeats the manual block of:

Power range low setpoint reactor trip, Intermediate range reactor trip, and intermediate range rod StoPS.

Provides input to P-7.
