l 3/4.3.2 ISOLATION ACTUATION INSTRUMENTATION LIMITING CONDITION FOR OPERATION

~

3.3.2 The isolation actuation instrumen,tation channels shown in Table 3.3.2-1 shall be OPERA 8LE with their trip setpoints set consistent with the vatues shown in the Trip 5etpoint column of Table 3.3.2-2 and with ISQLATION SYSTEM RESPONSE TIME as shown in Table 3.3.2-3.

APPLICA81LITY: As shown in Table 3.3.2-1. -

M:

a. With an isolation actuation instrumentation channel trip setpoint less conservative than the value shown in the Allowable Values -

column of Table 3.3.2-2, declare' the channel inoperable until the channel is restored to OPERA 8LE status with its trip setpoint adjusted consistent with the Trip 5etpoint value. -

b. With the number of OPERA 8LE channels less than required by the Minimum CPERA8LE Channels per Trip System requirement for one trip

. system, place that trip system in the tripped condition

within one hour. The provisions of Specification 3.0.4 are not applicable.

-~ ,

With the number of OPERA 8LE channels less than required by the c.

Minimum QPERABLE #

Channels per Trip System requirement.for both trip systems, place at 1 east one trip system ** in the tripped condition within one hour and take the ACTION required by Table 3.3.2-1.

"With a design providing only one channel per trip system, an inoperable channel need not be placed in the tripped condition where this would cause the Trip Function to occur. In these cases, the inoperable channet shall be restored to OPERABLE status within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or the ACTION required by Table 3.3.2-1 for that Trip Function shall be taken.

- If more channels are inoperable in one trip system than in the other, select that trip system to place in the tripped condition except when this would cause the Trip Function to occur.

.f 4.3.2.1 Each isolation actuation instrumentation channel shall be demonstrated CPERA8LE by the performance of the CHANNEL CHECK, CHANNEL FUNCTIONAL TEST and CHANNEL CALIBRATION operations for the OPERATIONAL CONDITIONS and at the frequencies shown in Table 4.3.2.1-1.

4.3.2.2 LOGIC SYSTEM FUNCTIONAL TESTS and simulate'd automatic operation of all channels shall be performed at least once per 18 months.

4.3.2.3 The ISOLATION SYSTEM RESPONSE TIME of each isolation trip function shown in Table 3.3.2-3 shall be demonstrated to be within its limit at least once per 18 months. Each test shall include at least one channel per trip system such that all channels are tested.at least once every N times -

18 months, where N is the total number of redundant channels in a specific isolation trip system.

INSTRUMENTATION 3/4.3.2 ISOLATION ACTUATION INSTRUMENTATION LIMITING CONDITION FOR OPERATION 3.3.2 The isolation actuation instrumentation channels shown in Table 3.3.2-1

-shall be OPERA 8LE with their tri'p setpoints set consistent with the values shown in the Trip'Setpoint column of Table 3.3.2-2 and with ISOLATION SYSTEM

. RESPONSE TIME as shown in Table 3.3.2-3.

APPLICA8ILITY: .As shown in Table 3.3.2-1.

ACTION:

a. With an isolation actuation instrumentation channel trip setpoint less conservative than the value shown in the Allowable Values column of Table 3.3.2-2, declare.the channel inoperable until the channel is restored to OPERABLE status with its trip setpoint adjusted consistent with the Trip Setpoint value. . ,

l

b. With the number of OPERABLE channels less than required by the Minimum OPERABLE Channels per Trip System requirement for one trip system; place that trip system in the tripped condition

within one hour. The provisions of Specification 3.0.4 are not applicable.

. c. With the number of OPERABLE channels less than required by the Minimum OPERA 8LE Channels per Trip System requirement for both trip systems, place at least one trip system ** in the tripped condition within one hour and take the ACTION required by Table 3.3.2-1.

"With a design providing only one channel per trip system, an inoperable channel need not be placed in the tripped condition where this would cause the Trip Function to occur. In these cases, the inoperable L

! channel shall be restored to OPERABLE' status witnin 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or the ACTION required by Table 3.3.2-1 for that Trip Function shall be taken.

- If more channels are inoperable in one trip system than in the other, select

. that trip system to place in the tripped condition except when this would cause the Trip Function to occur.

INSTRUMENTATION SURVEILLANCE REQUIREMENTS 4.3.2.1- Each isolation actuation instrumentation channel shall be demonstrated OPERABLE by the-performance of the CHANNEL CHECK, CHANNEL FUNCTIONAL TEST and

. CHANNEL CALIBRATION operations for the OPERATIONAL CONDITIONS and at the frequencies shown in Table 4.3.2.1-1.

4.3.2.2 LOGIC SYSTEM FUNCTIONAL TESTS and simulated automatic operation of all channels shall be performed at least once per 18 months.

4.3.2.3 The ISOLATION SYSTEM RESPONSE TIME of each isolation trip function shown-in Table 3.3.2-3 shall be demonstrated to be within its limit at least once per 18 months. Each test shall include at least one channel per trip system such that all channels are tested at least once every N times

18 months, where N is the total number of redundant channels in a specific isolation trip system.
