REACTOR COOLANT SYSTEM 3/4. 4'.'2 SAFETY VALVES SHUTDOWN LIMITING CONDITION FOR OPERATION s

3.4.2.1 A minimum of one. pressurizer code safety valve shall be OPERABLE.with a lift setting of 2500 psia t 1%.*

APPLICABILITY: MODE 4.

ACTION:

With no pressurizer code safety valve OPERABLE, immediately suspend all operations involving positive reactivity changes (except.cooldown in shutdown cooling) and place an OPERABLE shutdown cooling loop into operation.

4 SURVEILLANCE REQUIREMENTS 4.4.2.1 No additional Surveillance Requirements other than those required by Specification 4.0.5.

The lift setting pressure shall correspond to ambient conditions of the valve at nominal operating temperature and pressure.
