EMERGENCY CORE COOLING SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

10. Verifying that the following valves are in the indicated position with power to the valve operator removed:

Valve Number Valve Function Valve Position 2-51-306 Shutdown Cooling Open Flow Control 2-SI-659 SRAS Recirc. Open*

2-SI-660 SRAS Recirc. Open*

2-CH-434 Thermal Bypass Closed * *

b. By a visual inspection which verifies that no loose debris (rags, trash,-

clothing, etc.)is present in the containment which could be transported to the containment sump and cause restriction of the pump suctions during LOCA conditions. This visual inspection shall be performed:

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

2. Of the areas affected within containment at the completion of containment entry when CONTAINMENT INTEGRITY is established.

c. At least once per 18 months byt

1. Verifying automatic iso)Ation of the shutdown cooling system from the Reactor Cool 6nt System when the Reactor Coolant System pressure is above 300 psia.

2. A visual inspection of the containment sump and verifying that the subsystem suction inlets are not restricted by debris and that the sump components (trash racks, screens, etc.) show no evidence of structural di.} tress or corrosion,

3. Verifying that a minimum total of 110 cubic feet of trisodium phosphate dodecahydrate (TSP)is contained within the TSP storage baskets.

4. Verifying that when a representative sample of 0.35 1 005 lbs of TSP from a TSP storage basket is submerged, without agitation,in 501 5 gallons of 180 1 100F borated water from

the RWST, the pH of the mixed solution is raised to }6 within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

• To be closed prior to recirculation following LOCA.

. * *2-CH-434, a manual valve, shall be locked closed.
