END OF-CYCLE RECIRCULATION PUHP TRIP SYSTEM INSTRUMENTATION LIMITING CONDITION FOR OPERATION The end-of-cycle recirculation pump trip (E0C-RPT) system instrumen-3.3.4.2 tation channels shown in Table 3.3.4.2-1 shall be OPERABLE with their trip setpoint$ set' consistent with the values shown in the Trip Setpoint column of Table 3.3.4.2-2 and with the END-OF-CYCLE RECIRCULATION PUMP TRIP SYSTEM RESPONSE TIME as shown in Table 3.3.4.2-3.
APPLICABILITY: OPERATIONAL CONDITION 1, when THERMAL POWER is > to 40% of Tf4TED THERMAL POWER.
ACTION:
With an end-of-cycle recirculation pump trip function instrumentation a.
channel trip setpoint icss conservative than the value shown'in the Allowable Value column of Table 3.3.4.2-2, declare the channel inoperable until the channel is restored to OPERABLE status with the channel setpoint adjusted consistent with the Trip Setpoint value, With one of the four channels required for any Trip Function inoperablo, b.
operation may continue provided the inoperable channel is placed in the tripped condition within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. The provisions of Specification 3.0.4 are not applicabic.
With two of the four channels required for any Trip Function inoperable, l
c.
place one channel in the tripped condition within one hour provided no l
tripped channel fee that Trip Function already exists. The provisions of l
Specification 3.0.4 are not applicable.
With three of the f our channels required for any Trip Function inoperable,
(
l d.
reduce THERMAL POWER to less than 40% of RATED THERMAL-POWER within I
6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
SURVEILLANCE REOUIREMENTS 4.3.4.2.1 Each end-of-cycle recirculation pump trip system instrumentation channel shall be demenstrated OPERABLE by the performance of the CHANNEL FUNCTIONAL TEST and CHANNEL CAllBRATION operations at the frequencies shown in Tatile 4.3. 4.2-1.
LOGIC SYSTEM FUNCTIONAL TESTS shall be performed at least once per 4.3.4.2.-2 18 months. Divisional logic and portions of the channel coincident logic shall-be manually' test.ed independent of the SELF TEST SYSTEM during each refueling outage such that all trip functions'are tested at least once every four fuel cycles."
- Manual testing for the purpose of satisfying Specification 4.3.4.2.2 is not required until af ter shutdown during the first regularly scheduled refueling qutage.

SURVE1LLANCE REOUIREMENTS (Continued)
The EtiD-Of-CYCLE RECIRCULAT10!1 PUM? TRIP SYSTEM RESPONSE 11ME of 4,3,4,2,3 each trip function shown in Table 3.3.4.2-3 shall be demonstrated to be within its limit at least once per 18 months.
Each test shall include.at least the logic of one type of channel input, turbine control valve fast closure or turbine stop valve closure, such that both types of channel inputs are tested at least once per 36 months. %e eteasorQ +irnt. t; hall be adder) hi the sufpresst'on -M 0,nd We. re5.ulhlg'eihrt M r$t etm+ br u har ourt 12e4tg.rOL.Arterd IDMP TW-1f SYS77?A?
