=============================,*====================================
- 4. 6. 3.1. 2 Each isolation valve specified in Table 3*. 6-1 shall be demonstrated OPERABLE during the COLD SHUTDOWN or REFUELING MODE at least once per 18 months by:
- a.
Verifying that on a Phase A containment isolation test signal, each Phase A isolation valve actuates to its isolation position.
- b.
Verifying that on a Phase B containment isolation test signal, each Phase B isolation valve actuates to its isolation position.
- c.
Not Used.
- d.
Verifying that on a Containment Purge and Pressure-Vacuum Relief isolation test signal, each Purge and Pressure-Vacuum Relief valve actuates to its isolation position.
- e.
Verifying that the Containment Pressure-Vacuum Relief Isolation valves are limited to s 60° opening angle.
4.6.3.l.3 At least once per 18 months, verify that on a main steam isolation test signal, each main steam isolation valve specified in Table 3.6-1 actuates to its iqolation position.
4.6.3.1.4 The isolation time of each power operated or automatic valve of
~able 3.6-1 shall be determined to be within its limit when tested pursuant to Specification 4.0.5.
4.6.3.1.5 Each containment pur~e isolation valve shall be demonstrated OPERABLE within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after each closing of the valve, except when the valve is being used for multiple cyclings, then at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, by verifying that when the measured leakage rate is added to the leakage rates determined pursuant to Specification 4.6.l.2d. for all other Type B and C penetrations, the combined leakage rate is less than or equal to 0.60La.
4.6.3.l.6 A pressure drop test to identify excessive degradation of.resilient valve seals shall be conducted on the:
