CONTAINMENT SYSTEMS 3/4.6.6 PRIMARY CONTAINMENT ATMOSPHERE CONTROL DRYWELL AND SUPPRESSION CHAMBER HYOROGEN RECOMBINER SYSTEMS LIMITING CONDITION FOR OPERATION 3.6.6.1 Two drywell and two suppression chamber hydrogen recombiner systems shall be OPERABLE.

APPLICABILITY: OPERATIONAL CONDITIONS 1 and 2.

ACTION:

With one drywell and/or one suppression chamber hydrogen recombiner system inoperable, restore the inoperable system to OPERABLE status within 30 days or be in at least HOT SHUTDOWN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

SURVEILLANCE REQUIREMENTS 4.6.6.1 Each drywell and suppression chamber hydrogen recombiner system shall be demonstrated OPERABLE: -

a. At least once per 6 months by energizing the recombiner system to at least 10 kw for > 5 minutes.

b. At east once per 18 months by:

1. Performing a CHANNEL CALIBRATION of all recombiner operating instrumentation and control circuits.

2. Verifying the integrity of all heater electrical circuits by performing a resistance to ground test following the above required energization. The resistance to ground for any heater phase shall be greater than or equal to 10,000 ohms.

3. Verifying through c visual examination that there is no evidence of abnormal conditions within the recombiner enclosure; i.e, loose wiring or structural connections, deposits of foreign materials, etc.

ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) that current specified by the manufacturer for the test current.

l The magnetic (instantaneous) element shall be tested by injecting a current in excess of 120% of the pickup value of the magnetic (instantaneous) element and verifying that the circuit breaker trips instantaneously with no intentional time delay. Type HF8-M (magnetic only) circuit breaker testing shall also follow this procedure except that no thermal trip elements will be involved. Circuit breakers found inoperable during functional testing shall be restored to OPERABLE status prior to resuming operation. For each circuit breaker found inoperable during these functional tests, an additional representative sample of at least 10% of all the circuit breakers of the inoperable type shall also be functionally tested until no more failures are found or all circuit breakers of that type have been functionally tested.

2. a.By selecting and functionally testing a representative sample of each type of fuse on a rotating basis. Each representative <

sample of fuses shall include at least 10% of all fuses of that type. The functional test shall consist of a non-destructive

' resistance measurement test which demonstrates that the fuse meets its manufacturer's design criteria. Fuses found inoperable j during these functional testing shall be replaced with OPERABLE  ;

fuses prior to resuming operation. For each fuse found inoperable <

during these functional tests, an additional representative sample '

' of at least 10% of all fuses of that type shall be functionally l tested until no more failures are found or all fuses of that type have been functionally tested, or 4 b. By replacing 100% of all required fuses.

3. Functionally testing each overcurrent relay listed in Table 3.8.4.1-1. . Testing of these relays shall consist of injecting a current in excess of 120% of the nominal relay initiation current and measuring the response time. The measured response time shall be within 110% of the specified value.

b. At least once per 60 months by subjecting each circuit breaker to an l inspection and preventive maintenance in accordance with procedures prepared in conjunction with its manufacturer's recommendations. j 1
