3/4.2.4 DN8R MARGIN LIMITING CONDITION FOR OPERATION 3.2.4 The ONBR margin shall be maintained by one of the following methods:
a.
Maintaining COLSS calculated core power less than or equal to COLSS --
calculated core power operating limit based on DNBR (when COLSS.is in service, and either one or both CEACs are operable); or b.
Maintaining COLS$ calculated core power less than or equal ts COLSS-calculated core power operating iteit based on DNSR decreased by 13% RATED-THERMAL POWER (when COLS$ is in service and neither CEAC is operable); or c.
Operating within the region of acceptable operation of Figure 3.2-2 using any operable CPC channel (when COLS$ is out of service' and either one or both CEACs are operable); or d.
Operating within the region of acceptable operation of Figure 3.2-3 using any operable CPC channel (when COLS$ is out of service' and neither CEAC is operable).

LIMITING CONDITION FOR OPERATION I
3.2.4 The DNBR margin shall be maintained by one of the following methods:
a.
Maintaining COLSS calculated core power less than or equal to COLSS calculated core power operating limit based on DNBR (when COLSS is in service-.
and either one or both CEACs are operable); or 3
b.
Maintaining COLSS calculated core power less than or equal to COLSS calculated core power. operating limit based on DNBR decreased by 16% RATED
