A_. PPLICABILITY: As shown in Table 3.3.2-1.

ACTI0ti:

a.

With a CRVICS channel trip setpoint less conservative than the value shown in the Allowable Value column of Table 3.3.2-2, de setpoint adjusted consistent with the Trip Setpoint value, .'

b. For CRVICS Main Steam Line Isolation Trip Functions:

1.

With one of the four channels required for any Trip Function inopera-ble, operation may continue provided theThe inoperable provisionschannel of Speci-is placed in the tripped condition within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.

2.

With two of the four c .nnels required for any Trip Function inopera-ble, place one channel in the tripped condition within one hour provided no tripped channel for that Trip Function already exists.

The provisions of Specification 3.0.4 are not applicable. -

or l 3.

With three d 9 e four channels required for any Trip Function inoperable M e the ACTION required by Table 3.3.2-1.

c. For other CRVICS Isolation Trip Functions:

1.

With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Tr,ip System requirement for one trip system, place the inoperable channel (s) and/orofthat The provisions trip system Specification inare 3.0.4 the t, ripped condition ** within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

2.

With the number of OPERABLE channels less than required by the Min OPERABLE Channels per Trip System requirem and take the ACTION required by Table 3.3.2-1.

SURVEILLANCE REQUIREMENTS Each CRVICS channel shall be demonstrated OPERABLE tions by the perform 4.3.2.1 of the CHANNEL CHECK, CHANNEL FUNCTIONAL 4.3.2.2 18 months.

LOGIC SYSTEM FUNCTIONAL TESTS shall SELF be perfor the chanrel coincident logic shall be manually tested independent of the'Eac TEST SYSTEM during each refueling outage.

divisions of the CRVICS tri.p system logic rshall be alternately t and manuall tested independent of the SELF TEST SYSTEN during eve'y' othef iefueling o All manual testing shall be completed such that all tri_p functions are teste at least once every four fuel cycles.**

'4.3.2.3 The CRVICS RESPONSE TIME of each CRVICS trip function shown in Table 18 months.

3.3.2-3 shall be demonstrated to be withinl its limit at l once per 36 months, and one channel per trip function of redundant channels in a specific CRVICS trip function.

i ld "The trip system need not be placed in the tripped condition if th s. wou cause the Trip Function to occur. . When.a trip -system can be'placed i in the tripped condition without causing the Trip Function to occur, place the tr p system systems have th2 with the most inoperable. channels in the tripped in the tripped condition.
