b. With less than the minimum number of radioactive liquid effluent monitoring instrumentation channels OPERABLE, take the ACTION shown in Table 3.3 12.

Exert best efforts to restore the inoperable instrumentation to OPERABLE status within 30 days

and, if i

unsuccessful, explain in the next Semiannual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

With the number of channels OPERABLE less than required by the ACTION 32 Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided best efforts are made to repair the instrument and that grab samples are analyzed for gross radioactivity (beta or y mma) at a lower limit of detection of no more than 3 x 10 microcurie /ml:

l a.

At least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> when the specific activity of 4

the secondary coolant is less than or equal to 0.01 microcurie / gram DOS EQUIVALENT I 131.

ACTION 33 With the number of channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided that best efforts are made 1

to repair the instrument and that the flow rate is estimated at 2

least once per 4

INSTRUMENTATION RADI0 ACTIVE GASE0VS EFFLUENT MONITORING INSTRUMENTATION LIMITING CONDITION FOR OPERATION 3.3.3.10 The radioactive gaseous effluent monitoring instrumentation channels shown in Table 3.3-13 shall be OPERABLE with their Alarm / Trip Setpoints set to ensure that the limits of Specifications 3.11.2.1 are not exceeded.

The alarm / Trip Setpoints of these channels shall be determined in accordance with the methodology and parameters in the REM 00CM.

APPLICABILITY: As shown in Table 3.3-13 ACTION:

a. With a

radioactive gaseous effluent monitoring instrumenthtion channel Alarm / Trip Setpoint less conservative than required by the above specification, without delay suspend the release of radioactive gaseous effluents monitored by the affected channel, or decl are the channel inoperable, or change the setpoint so it is acceptaoly conservative.

b. With the number of OPERABLE radioactive gaseous effluent monitoring instrumentation channels less than the Minimum Channels OPERABLE, take the ACTION shown in Table 3.3-13.

Exert best efforts to restore the inoperable instrumentation to OPERABLE status within 30 days

and, if unsuccessful, explain in the next Selannual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

Releases need not be terminated af ter 30 days provided the specified actions are continued.

c. The provisions of Specifications 3.0.3 and 3.0.4 are not applicable.

SURVEILLANCE RE0VIREMENTS 4.3.3.10 Each radioactive gaseous effluent monitoring instrumentation channel shall be demonstrated OPERABLE by performance of the CHANNEL CHECK, SOURCE

CHECK, CHANNEL CALIBRATION and ANALOG CHANNEL OPERATIONAL TEST at the frequencies shown in Table 4.3-9.
