2. Verifying the correct position of each mechanical position stop for each of the stop check valves listed in Specification 4.5.2.c.

3. Verifying that the flow controllers for the throttle valves listed in Specification 4.5.2.d. operate properly.

4. A visual inspection of the containment emergency sump which verifies that the subsystem suction inlets are not restricted by debris and that the sump components (trash racks, screens, etc.) show no evidence of structural distress or corrosion.

5. Verifying a total leak rate less than or equal to 6 gallons per hour for the LPI system at:

a) Normal operating pressure or a hydrostatic test pressure of greater than or equal to 150 psig for those parts of the system downstream of the pump suction isolation valve, and b) Greater than or equal to 55 psig for the piping from the contain-ment emergency sump isolation valve to the pump suction isolation valve.

f. At least once per 18 months during Mode 3, 4, 5, or 6.

1. Verifying that each automatic valve in the flow path actuates to its correct position on a high pressure or low pressure safety injection test signal, as appropriate. l

2. Verifying that each HPI and LpI pump starts automatically upon receipt of a high pressure or low pressure safety injection test signal, as appropriate. l

g. Following completion of HPI or LPI system modifications that could have altered system flow characteristics 1, by performance of a flow balance test during shutdown to confirm the following injection flow rates into the Reactor Coolant System:

HPI System - Sincie pump 2 LpI System - Sinale pump Single pump flow rate greater than or 1. Injection Leg A -

equal to 500 gpm at 600 psig. 2800 to 3100 gpm.

While injecting through 4 injection Legs, 2. Injection Leg B -

the flow rate for all combinations of 3 2800 to 3100 gpm.

Injection Legs greater than or equal to 350 gpm at 600 psig.

1 Flow balance tests performed prior to complete installation of modifi cations are valid if performed with the system change that could alter flow characteristics in effect.

2 The HPI Flow Balance Test shall be performed in MODE 3.
