'3.13 ACCIDEWT MONITORING INSTRUMENTATION Applicability:

Applies to the operating status of accident monitoring instrumentation.

Objective:

To assure operability of accident monitoring instrumentation.

Specification:

A.

Relief Yalve Position Indicators 1.

The accident monitoring instrumentation channels shown in Table 3.13.1 shall be OPERABLE when the l

mode switch is in the Startup or Run positions.

2.

With the number of OPERABLE accident monitoring i

instrumentation channels less than the Total Number of Channels shown in Table 3.13.1, either restore the inoperable channels to OPERABLE status within 7 days, or place the reactor in the SHUTOOWN CONDITION within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

3.

With the number of OPERABLE accident monitoring i

instrumentation channels less than the Minimum Channels Operable requirements of Table 3.13.1, eitl er restore the inoperable channel (s) to the OPERABLE status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, or place the reactor in the SHUTDOWN CONDITION within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

B.

Safety Valve Position Indicators 1.

During POWER OPERATION, both primary

• and backup **

l safety valve monitoring instruments are required to be OPERABLE except as provided in 3.13.B.2.

l 2.

If the primary

• accident monitoring instrument on a safety valve becomes inoperable, the primary

• accident monitoring instrument on an adjacent valve, if operable, must have its set point appropriately reduced.

If the backup ** accident monitoring instrument on a safety valve becomes inoperable, no action is required, t

s 3.

If the requirements of Specification 3.13.B.2 cannot be met, POWER OPERATION is permitted until Specification 3.13.C is met.

C.

In the event that any-of these monitoring channels become inoperable, they shall be'made OPERABLE prior to startup following the next COLD SHUTDOWN.

D.

Wide Range Torus Water' Level Monitor 1.

Two wide range torus water level monitor channels shall be continuously indicated in the control room durina Power Operation.

2.

With the number of operable accident monitoring channels less than the total Number of Channels shown in Table 3.13.1, restore the inoperable channel (s) to Operable status within 7 days or place the reactor in the shutdown condition within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

3.

With the number of operable accident monitoring instrumentation channels less than the Minimum Channels operable requirements of Table 3.13.1, restore the inoperable channel (s) to operable status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or place the reactor in the shutdown condition within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

E.

Wide Range Drywell Pressure Monitor 1.

Two Wide Range Drywell Pressure monitor channels shall be continuously indicated in the control room during Power Operation.

2.

With the number of operable accident monitoring channels less than the total Number of Channels shown in Table 3.13.1, restore the inoperable channel (s) to Operable status within 7 days or place the reactor in the shutdown condition within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

3.

With the number of operable accident monitoring instrumentation channels less than the Minimum Channels operable requirements of 3.13.1, restore the inoperable channel (s) to operable status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or place the reactor in the shutdown condition within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

F.

Drywell Hp Monitor 1.

Two drywell hydrogen monitor channels shall be capable of continuously indicating in the control room during power operation.
