PRIMARY-00Nrf.INMENT HYDROGEN REQNBINER SYSTEMS LIMITING CONDITION FOR OPERATION 3.6.6.2 Two indepe M ent primary containment hydrogen recombiner systems shall be OPERABLE.
APPLICABILITY: CONDITIONS 1 and 2.
ACTION With one hydrogen recombiner system inoperable, restore the inoper-a.
j able system to OPERABLE status within 30 days or be in at least HOT SHlfrDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The provisions of Specification 3.0.4 are not applicable.
b.
With both hydrogen recombiner systems inoperable, be in at least H0ff SHTIDOWN within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

SURVEILLANCE REQllIREMENTS-4.6.6.2 Each hydrogen recombiner system shall be demonstrated OPERABLE:
At least once per 6 months by verifying during a recombiner a.
system functional test 'that the ministmi heater sheath temperature increases to > 6000F within 60 minutes and is maintained for at least 2 hoiirs.
b.
At least once per 18 months by:
1.
Performing a OIANNEL CALIBRATION of all recombiner instru-mentation and control circuits.
2.
Verifying through a visual examination that there is no evidence of abnonnal conditions within the recombiners 4
+-
(i.e., loose wiring or structural connections, deposits
'l of foreign materials, etc.)
t 3.
Veritying during a recombiner system functional test that the heater sheath temperature increases to > 1200'F within 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> and is maintained between T1500F and 13000F for at least 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
4 Verifying the integrity of all heater electrical circuits by perfonning a continuity and resistance to ground test i
following the above required functional test. The resis 6 tance to ground for any heater element shall be > 1.0 x 10 l
j ohms.
