ll 3.4 STEAM AND POWER. CONVERSION' SYSTEM..

1 Applicability i

Applies to the turbine cycle components for removal of reactor decay heat.

1 Objective l

To specify minimum conditions of the turbine cycle equipment 'necessary to 1

assure'the capability to remove decay heat from the reactor core.

Specifications 3.4.1l J he reactor.shall not be heated above 280 F unless'the following conditions are met:

1.

Capability to remove decay heat by use of two steam generators.

I

• 2.

Fourteen of the steam system safety. valves are operable.

3.

A minimum of.11.1 feet (107,000 gallons) of water is available in Tank T418.

• • 4.

Both EFW pumps and their flow paths are operable.

5.

Both main steam block valves and both main feedwater isolation valves are operable.

3.4.2 Initiate functions of the EFIC system-which are bypassed at' cold shutdown conditions shall have the following minimum operability.

conditions:

a.

" low steam generator pressure" initiate shall be operable when the main steam pressure exceeds 750 psig.

J b.

" loss of 4 RC pumps" initiate shall be operable when neutron flux exceeds 10% power.

c.

" main feedwater pumps tripped" initiate shall be operable when neutron flux exceeds 10% power.

• Except that during hydrotests, with the reactor subcritical,. fourteen of j

the steam system. safety valves ~may be gagged and two (one on each header),

l inay be reset for _the duration of the test, to allow the required pressure for.the test to'be attained.

..j

• • Except that a test with available steam. pressure of the steam' driven EFW' l

pump shall demonstrate its functionality'until completion of. surveillance,

i testing at hot shutdown' conditions as required by Surveillance' Requirement'4.8.1.
