3/4.5 EMERGENCY CORE COOLING SYSTEMS 3/4. 5.'l HIGH PRESSURE COOLANT INJECTION SYSTEM LIMITING CONDITION FOR OPERATION 3.5.1 The High Pressure Coolant Injection (HPCI) system shall be OPERABLE with:

a. One OPERABLE high pressure coolant injection pump, and

b. An OPERABLE flow path capable of taking suction from the suppression chamber and transferring the water to the reactor pressure vessel.

APPLICABILITY: CONDITIONS 1*, 2* and 3* with reactor vessel steam dome pressure

> 150 psig. j ACTION: _ j

a. With the HPCI system inoperable, POWER OPERATION may continue  ;

and the provisions of 3.0.4 do not apply *, provided the RCIC '

system, ADS, CSS and LPCI system are OPERABLE; restore the inoperable HPCI system to OPERABLE status within 14 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 reduce reactor steam dome pressure to f 150 psig within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />,

b. With the surveillance requirements of Specification 4.5.1 not performed at the required frequencies due to low reactor steam pressure, the provisions of Specification 4.0.4 are not applic-able provided the appropriate surveillance is performed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reactor steam pressure is adequate to perform the tests.

c. In the event the HPCI is actuated and injects water into the reactor coolant system, a Special Report shall be prepared and l submitted to the Commission pursuant to Specification 6.9.2 within 90 days describing the circumstances of the actuation and the total accumulated actuations cycles to date.

SURVEILLANCE REQUIREMENTS 4.5.1 The HPCI shall be demonstrated OPERABLE: I

a. At least once per 31 days by:

1. Verifying that the system piping from the pump discharge valve to the system isolation valve is filled with water, '

and

• See Special Test-Exception 3.10.5 FATCH - UNIT 2 39 5-1

SPECIAL TEST EXCEPTION HIGH PRESSURE COOLANT INJECTION SYSTEM LIMITING CONDITIONS FOR OPERATION 3.10.5 The requirements of Specification 3.5.1 are modified to not require HPCI to be operable before entry into another operational condition in order to perform a one time test of the turbine-generator up to 10% RATED POWER with the generator not aligned to the system grid for a time period not to exceed 7 days.

APPLICABILITY: CONDITIONS 1, 2 and 3.

ACTION:

With the above specified limits exceeded, actuate an immediate power reduction to less than 10% power. -

SURVEILLANCE REQUIREMENTS 4.10.5 Verify once per hour that power level is (110% of rated power.
