T INSTRUMENTATION BASES e

3/4.3/10 APPENDIV. R ALTERNATIVE SHUTDOWN INSTRUMENTATION AND CONTROLS The OPERABILITY of the alternative shutdown system ensures that a fire will not preclude achieving safe shutdown. The alternative shutdown system instrumentation. control circuits, power circuits and transfer switches are independent of areas where a fire could damage systems normally used to shutdown the reactor. Thus, capability is consistent with General Design Criterion 3 Appendix R t o 10 CFR 50.

3/4.7 PLANT SYSTEMS r

3/4'7.9'APPENDIY R ALTFRNATIVE SHUTDOWN AUXILIARY SYSTEMS.

LIMITING' CONDITION FOR OPERATION 3.7.9 The Appendix R. Alternative Shutdown auxiliary systems shall be OPERABLE as described below:

a. A Standby Feedwater (SBFW) System consisting of one OPERABLE SBFW~ pump and a flow path from the condensate storage tank to the reactor vessel.
b. An OPERABLE CTG Unit 1 and power train capable of supplying power to;the 64C Bus via its Peaker Bus.
c. An OPERABLE Drywell Cooling Unit (either B001 or B002) consisting of a fan and cooling coil capable of being fed from

-EECW system.

d. The provisions of specification 3.0.4 are not applicable.

APPLICABILITY: OPERATIONAL. CONDITIONS I and 2 ACTION:

a. With the SBFW system inoperable. restore the system to OPERABLE status within 7 days or be in at least HOT.

b. With an inoperable CTG Unit 1 verify the 120 KV bus is available by performing surveillance 4.8.1.1.1 and
1. Within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, establish a roving fire watch for all the

- fire zones where Appendix R Alternative Shutdown is

^

utilized.

2. Within 30 days, restore CTC-Unit I to OPERABLE status or-provide an alternative source of power to the Alternate Shutdown bus.

3..Within 60 days, restore CTG Unit 1 to OPERABLE status or be in.at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in COLD SHUTDOWN within'the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

c. With both drywell cooler unita B001 and B002 inoperable, restore at least one to OPERABLE status within 7 days or be in at least HOT SHUTDOWN within the next'12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in COLD SHUTDOWN within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

a PLANT SYSTEMS SURVEILLANCE REOUIREMENTS 4.7.9.1 The SBFW system shall be demonstrated OPERABLE at least once every 92 days by conducting a flow test.

4.7.9.2:The CTG Unit I system shall be demonstrated OPERABLE by starting and supplying load to the Peaker Bus at least once every 31 days.

4.7.9.3 Either one of the Drywell Cooling Units B001 and B002 shall be verified-to be capable of performing its intended function at least once every 31 days.

PLANT SYST M BASES B3/4.7.9 APPENDIX R ALTERNATIVE SHUTDOWN AUXILIARY SYSTEMS The systems identified in this section are those utilized for Appendix R Alternate Shutdown but not included in other sections of the Technical Specifications. The action statements assure that the auxiliary systems will be OPERABLE or that acceptable alternative means

'are established to achieve the same objective.
