PLANT SYSTEMS EMERGENCY BOILER FEEDWATE9 SYSTEM LIMITING CONDITION FOR OPERATION 3 7.1.?
The emergency boiler feedwater systen shall be OPERABLE with the emergency boiler feedwater pump capable cf being powered f-om an CPERABLE steam supply system.
APPLICABILITY: MODES 1, 2, and 3 ACTION:
'".th the emergency boiler feedwater system inoperable, be in at least HOT STANDBY within one hour and in 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 />.
SURVEILLANCE REQUIREMENTS 4.7 1.2 The emergency boiler feedwater system shall be demonstra.ted OPEN.BLE:
a.
At least once per 15 days by:
Starting the pump, 2.
Verifying that, on recirculation flow, the steam turbine drive.7 pump develops a discharge pressure of 1950 psig when the secondary steam pressure is greater than 100 psig, 3
Verifying that the pump operates for at least 15
- minutes, 4.
Cycling each testable manual valve in the flow path through at least one complete cycle of full travel, and 5.
Verifying that each valve in the flow path that could interrupt all Emergency Boiler Feedwater flow is locked open and the remaining valves are verified to be in the correct position, b.
At least once per 18 months during shutdown by:
1.
Cycling each manual valve in the flow path that is not testable during plant operation, through at least one complete cycle of full travel.
2.
Verifying that the steam turbine driven pump develtps a discharge pressure of 1950 psig at a flow of 180 gpm while feeding a steam generator.
3 Cycling each main feed control val've manually through at least one complete cycle of full travel.

l PL_ ANT SYSTEMS SURVEILLANCE REQUIREMENTT,(Continued) c.
Prior to startup from cold shutdown:
1.
Verify that each valve in the flow path from the Emergency Boiler Feedwater Source to the Main Feedwater Lines is properly aligned to provide an uninterrupted flow path to the Main Feedwater System from the Emergency Boiler Feedwater System, and 2.
Perform a flow test from the Emergency Boiler Feedwater Source to the Steam Generator to verify the normal flow path.
