~DTED BRUNE 2, 1992 INSTRUMENTATION 3/4.3.3 EMERGENCY CORE COOLING SYSTEM ACTUATION INSTRUMENTATION LIMITING CONDITION FOR OPERATION

3. 3. 3 The emergency core cooling system (ECCS) actuation instrumentation channels shown in Table 3.3.3-1 shall be OPERABLE with their trip setpoints set consistent with the values shown in the 'Trip Setpoint column of Table 3.3.3-2 and with EMERGENCY CORE COOLING SYSTEM RESPONSE TIME as shown in Table 3.3.3-3.

APPLICABILITY:

As shown in Table 3.3.3-1.

ACTION:

a ~

C.

Mith an ECCS actuation instrumentation channel trip setpoint less conservative than the value shown in the Allowable Values column of Table 3.3.3-2, declare the channel inoperable until 'the channel is restored to OPERABLE status with its trip setpoint adjusted consistent with the Trip Setpoint value.

Mith one or more ECCS actuation instrumentation channels inoperable, within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> take the ACTION required by Table 3.3.3-1.

With either ADS trip system "A" or "B" inoperable, restore the inoperable trip system to OPERABLE status:

1.

Within 7 days, provided that the HPCS and RCIC systems are OPERABLE; otherwise, 2.

Within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

Otherwise, be in at least HOT SHUTDOMN within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and reduce reactor steam dome pressure to less than or equal to 128 psig within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

SURVEILLANCE RE UIREMENTS 4.3.3. 1 Each ECCS actuation instrumentation channel shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL FUNCTIONAL TEST, and CHANNEL CALIBRATION operations for the OPERATIONAL CONDITIONS and at the frequencies shown in Table 4.3.3. 1-1.

4.3.3. 2 LOGIC SYSTEM FUNCTIONAL TESTS and simulated automatic operation of all channels shall be performed at least once per 18 months.

4. 3. 3. 3 The ECCS

RESPONSE

TIME of each ECCS trip function shown in Table 3. 3.3-3 shall be demonstrated to be within the limit at least once per 18 months.

Each test shall include at least one channel per trip system such that all channels are tested at least once every N times 18 months where N is the.

total number of redundant channels in a specific ECCS trip system.

• Response time testing of the Low Pressure Systems as specified in Technical Specification Table 3.3.3-3, items 1 and 2 is not a requirement for OPERABILITYuntil the startup following the next COLD SHUTDOWN, but no later than the startup followingthe Spring 1994 Refueling Outage.
