- Whenever both RHR subsystems are inoperable, if unable to attain COLD SHUTDOWN as required by this ACTION, maintain reactor coolant temperature as low as practical by use of alternate heat removal methods.
- The allowed outage time (A0T) of the "A and B" loops of suppression pool spray mode may be extended up to 288 hours (12 days) to allow for the installation of isolation valves upstream of HV-51-1(2)F014A(B) and downstream of HV-51-1(2)F068A(B) during the fifth Unit I refueling outage (IR05).

SURVEILLANCE REQUIREMENTS 4.6.2.3 The suppression pool cooling mode of the RHR system shall be demonstrated OPERABLE: a. At least once per 31 days by verifying that each valve (manual, power-operated, or automatic) in the flow path that is not locked, sealed, or otherwise secured in position, is in its correct position. b. By verifying that each of the required RHR pumps develops a flow of at least 10,000 gpm on recirculation flow through the flow path including the RHR heat exchanger and its associated closed bypass valve, the suppression pool and the full flow test line when tested pursuant to Specification 4.0.5.
- Whenever both RHR subsystems are inoperable, if unable to attain COLD SHUTDOWN as required by this ACTION, maintain reactor coolant temperature as low as practical by use of alternate heat removal methods.
- The allowed outage time (A0T) of the "A" and "B" loops of suppression pool cooling mode may be extended up to 288 hours (12 dsys) to allow for installation of isolation valves upstream of HV-51-1(2)F014A(B) and downstream of HV-51-1(2)
