3/4.6.2 DEPRESSVRIZA1101 AND COOLING SYSTEMS CONTAINMENT SPRAY SYSTEM LIMITING CONDITION FOR OPERATION 3.6.2.1 Two independent Containment Spray Systems shall be OPERABLE with each Spray System capable of taking suction from the RWST* and automatically trans-ferring suction to the containment sump.
APPLICABILITY: MODES 1, 2, 3, and 4.

SVRVEILLANCE RE0VIREMENTS 4.6.2.1 Each Containment Spray System shall be demonstrated OPERABLE:
a.
At least once per 31 days by verifving that each valve (manual, power-operated, or automatic) ir flow path that is not locked, sealed, or otherwise secured i-on is in its correct position; b.
By verifying, that on recircul, aw, each pump develops a differential pressure of greatei
, or equal to 262 psi when tested pursuant to Specification 4.0.5; c.
At least once per 18 months during shutdown, by:
1)
Verifying that each automatic valve in the ficw path actuates to its correct position on a Containment Pressure-Hi-3 test signal, and 2)
Verifying that each spray pump starts au'cMatically on a Containment Pressure-Hi-3 test signal.
d.
At least once per 10 years by performing an air or smoke flow test through each spray header and verifying each spray nozzle is l
unobstructed.
- In MODE 4, when the Residual Heat Removal System is in operation, an OPERABLE flow path is one that is capable of taking suction from the refueling water storage tank upon being manually realigned.
