Revision 30' Page 1 of 14 Init Date T30-22 EMERGENCY CORE COOLING SYSTEM VALVE TESTS 1.0 PURPOSE 1.1 Verify the operability of M0-7051,'MO-7061, M0-7066, M0-7070, M0-7071 and MO-7080 by remote manual operation.
1.2 Provide valve timing documentation per ASME Boiler and Pressure Vessel Code Section XI, IWV Testing.
1.3 Verify the deluge isolation valve, CV-4101 closes anytime a core spray valve opens and automatically reopens when all core spray valves are closed.
1.4 Verify that check valves VPI-303 and VPI-304 adequately seat, thereby preventing leakage from the high pressure coolant system into the low pressure core spray system.
2.0 PRECAUTIONS AND LIMITATIONS 2.1 When stroking motor-operated valves during this test, only one valve (of the valves being tested) may be open at a time.
2.2 During testing when MO-7051, MO-7061, M0-7070 and M0-7071 are opened, the substation deluge isolation valve CV-4101 will close to remove fire suppression capability for transformer sprays and the local trouble alarm will sound for FPS trouble.
2.3 If the fire main pressure increases to > 170 psig, as indicated on PI-338/PR-52, immediately close the core spray valve that was opened. A momentary pressure increase is normal, but a continued increase may indicate leakage of reactor coolant into the fire main.

Rsvision 30 T30-22 Page 2 of 14 Init Date 2.4 The storm drain located northeast of the escape lock directs the discharge of the core spray heat exchanger-to the lake.
If the drain culvert becomes plugged, the discharge of the heat exchanger will flood out of the drain box into the yard.
Under'this condition, the capacity of the heat exchanger is not affected unless freezing conditions exist and the water in the drain box is allowed to freeze.
If the culvert becomes plugged initiate a Maintenance Order to clean it out.
If this condition occurs in freezing weather, steps shall be taken to prevent freezing and to remove the standing wate from the drain box.
3.0 PREREQUISITES 3.1 The fire water system shall be operable and CV-4101 open.
