SURVEILLANCE RE0VIREMENTS 4.6.4.2 Each Hydrogen Recombiner System shall be demonstrated OPERABLE:

f a.

At least once per 6 months by verifying during a Hydrogen Recombiner System functional test that the minimum reaction chamber gas temper-ature increases to greater than or equal to 700'F within 90 minutes and is maintained for at least 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months and that the purge blower operates for 15 minutes.

l b.

At least once per 18 months by:

1)

Performing a CHANNEL CALIBRATION of all recombiner instrumenta-l tion and control circuits, l

2)

Verifying through a visual examination that there is no evi-dence of abnormal conditions within the recombiner enclosure (i.e., loose wirin foreign materials,g or structural connsctions, deposits of etc.),

3)

Verifying the integrity of all heater electrical circuits by performing a resistance to ground test following the above required functional test. The resistance to ground for any heater phase shall be greater than 10,000 ohms, and 4)

Verifying during a recombiner system functional test using con -

tainment atmospheric air at a flow rate of greater than or l

equal to that indicated on Figure 3.6-2, that the gas tempera-

?

ture increases to greater than or equal to 1100'F within 5 l

hours and is maintained for at least 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .
