SURVEILLANCE RE0VIREMENTS (continued) b.

At least once'per 18 months, or prior to operation after ECCS piping has been drained by verifying that the ECCS piping is full of water by venting the ECCS pump casings and discharge piping high points.

By a visual inspection which verifies that no loose debris (rags,be c.

trash, clothing, etc.

is present in the containment which could transported to the con)tainment emergency sump and cause restriction of the pump suction during LOCA conditions. This visual inspection shall be perforfbed:

i 1.

For all accessible areas of the containment prior to establishing CONTAINMENT INTEGRITY, and i

2.

For' all areas of containment affected by an entry, at least once daily while work is ongoing and again during the final exit after completion of work (containment closecut) when CONTAINMENT INTEGRITY is established.

d.

At least once per 18 months by:

1 1.

Verifying that the interlocks:

a)

Close DH-11 and DH-12 and deer,ergize the pressurizer heaters, if either DH-11 or DH-12 is open and a simulated reactor coolant system ressure which is greater than the trip setpoint (<438 psi )is not required if the valve is is applied. The interlock to close DH-11 and/or DH-1 closed and 480 V AC power is disconnected from its motor operators.

b)

Prevent the opening of DH-11 and DH-12 when a simulated or actual reactor coolant system pressure which is greater than the trip setpoint (<438 psig) is applied.

2.

a)

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).

b)

Verifying that on a Borated Water Storage Tank (BWST)

Low-Low Level interlock trip with the motor operators for the BWST outlet isolation valves and the containment emergency sump recirculation valves energized, the BWST Outlet Valve HV-DH7A (HV-DH78) automatically close in 575 t

seconds after the operator manually pushes the control switch to open the Containment Emergency Sump Valve HV-DH9A (HV-DH98) which should be verified to open in 175 seconds.

l 3.

Verifying a total leak rate 120 gallons per hour for the LPI system at:

a)

Normal operating pressure or hydrostatic test pressure of 1 l

150 psig for those parts of the system downstream of the pump suction isolation valve, and b)

> 45 psig for the piping from the containment emergency sump Tsolation valve to the pump suction isolation valve.
