3.10.3 The limitations of Specifications 3.1.1.4, 3.1.3.1, 3.1.3.5_ and 3.1.3.6 may be suspended during the performance of PHYSICS TESTS provided:

a.

The THERMAL POWER does not exceed 5% of RATED THERMAL POWER, l

b.

The reactor trip setpoints on the OPERABLE Intermediate Range Channels are set at less than or equal to 35% of RATED THERMAL POWER, and -

c.

The reactor trip setpoints on the OPERABLE Power Range Channels are set at less than or equal to 25% of RATED THERMAL. POWER.

AEPLICABILITY: MODE 2.
