APPLICABILITY:

OPERATIONAL CONDITIONS l~ and 2*.

ACTjON:

a.

Mith one reactor coo1ant system recirculation loop not in operation:

1.

Verify that the requirements of LCO 3.2.6 and LCO 3.2.8 are met, or comply with the associated ACTION statements 2.

Verify that THERMAL POMER/core flow conditions lay outside Region 8 of Figure 3.4.1.1-1.

With THERMAL POWER/core flow conditions which lay in Region 8

of Figure 3. 4. l. 1-1, as soon as practical, but in a11 cases within 15 minutes, initiate action to exit Region 8 by either decreasing THERMAL POWER with control rod insertion or increasing core flow with flow control valve manipulation.
