REACTIy!TY CONTROL SYSTEMS BORON DILUTION LINITING CONDITION FOR OPERATION 3.1.2.9 Boron concentration shall be verified consistent with SHUTDOWN MARGIN requirements of Specifications 3.1.1.1, 3.1.1.2, and 3.9.1.

Baron dilution events shall be precluded by:

Either two boron dilution alarms (startup channel high neutron flux) a.

shall be OPERABLE with the alarms set in accordance with Specifica-tion 4.1.2.9.5 or the primary makeup water flow path to the Reactor Coolant System shall be isolated, and b.

1.

When in Mode 5 with reactor coole,nt loops not filled and 0.98 1K,fft 0.96 isolate and remove power to at least two charging pumps; or 2.

When in Mode 5 with reactor coolant loops not filled and 0.96 1K,fft 0.94 isolate and remove power to at least one charging pump; or 3.

When in Mode 5 with reactor coolant loops not filled and three charging pumps are operable, maintain X,ff <0.94; and When in Mode 6, isolate and remove powar to at least two charging c.

pumps.

APPLICA8ILITY: MODES 3, 4, 5, and 6.

ACTION:

i a.

With the boron concentration not consistent with required SHUTDOWN MARGIN, initiate emergency boration.

(

b.

With one boron dilution alarm inoperable and the primary makeup water flow path to the Reactor Coolant Systes not isolated, determine Reactor Coolant System Doron concentration within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months and at least at the monitoring frequency specified in Tables 3.1-1 through 3.1-5.

With both boron dilution alarms inoperable and the primary makeup c.

water flow path to the Reactor Coolant System not isolated, determine the Reactor Coolant Systes boron concentration by two independent means within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months and at least at the monitoring frequency specified in Tables 3.1-1 through 3.1-5; otherwise, immediately suspend all operations involving positive reactivity changes or CORE ALTERATIONS (if applicable).
