Surveillanca Standards i

4.35 HYDROGEN REC 0f1BINERS Aeplicability Applies to testing of each Hydrogen Reccabiner System Objective To verify that the Hydrogen Recombiner Systems are OPERABLE.

Specification 4.35.1 Each Hydrogen Recombiner System shall be demonstrated OPERABLE:

4.35.2 At least once per 6 months by verifying during a recombiner system functional test that the minimum hgater sheath temperature increases to greater than or equal to 700 F within 90 minutes.

Upon reaching 700*F, increase the power setting to maximum power for 2 minutes and verify that the power meter reads greater th'an or equal to 60KW.

4.35.3 At least once per refueling interval by:

4.35.4 Performing a CHANNEL CALIBRATION of all recombiner t

instrumentation and functional tests of all control circuits, 4.35.5 Verifying through a visual examination that there is no evidence of abnorum1 conditions within the recombiner enclosure, and 4.35.6 Verifying the integrity of the heater electrical circuits by performing a resistance to ground test following the above required functional test. The resistance to ground for the heater unit shall be greater than or equal to 10,000 ohms.

Bases The OPERABILITY of the equipment and systems required for control of hydrogen gas ensures that this equipment will be available to maintain the i

hydrogen concentration within containment below its flammable Ifmit during post-LOCA conditions.
