TABLE 4.3-2 (Continued)

TABLE NOTATION (1) When shut down with main coolant pressure < 1000 psig, if not performed within the previous 31 days.

(2) When shut down longer than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, if not performed in the previous 31 days.

I (3) The test shall include exercising the sensor by applying either a vacuum or pressure to the appropriate side of the sensor.

(4) When in COLD SHUTDOWN with main coolant pressure < 300 psis, if not performed within the previous 31 days.

(5) Monthly surveillance shall be performed on the degraded voltage protection only.

Surveillance of loss of voltage protection shall be performed at least once per 18 months.

Not required in this MODE with main coolant pressure < 300 psig.

I Not required in this MODE with main coolant pressure < 1700 psig.
