3.2.7 REACTOR

COOLANT SYSTEM ISOLATION VALVES 4.2.7 REACTOR COOLANT SYSTEM ISOLATION VALVES Applicability:

Applies to the operating status of the system of isolation valves on lines connected to the reactor.coolant system.Objective:

To assure the capability of the reactor coolant system isolation valves to minimize reactor coolant loss in the event of a rupture of a line connected to the nuclear steam supply system, and to minimize potential leakage paths from the primary containment in the event of a loss-of-coolant accident.Specification:

a. Whenever fuel is in the reactor vessel and the reactor coolant temperature is greater than 212 0 F, all reactor coolant system isolation valves on lines connected to the reactor coolant system shall be operable except as specified in Specification 3.2.7.b below.b. In the event any isolation valve becomes inoperable whenever fuel is in the reactor vessel and the reactor coolant temperature is greater than 2-12'F, the system shall be considered operable;provided that within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> at least one valve in each line having an inoperable valve is in the mode corresponding to the isolated condition, except as noted in Specification 3.1.1.e.Applicability:

Applies to the periodic testing requirement for the reactor coolant system isolation valves.Obiective:

To assure the capability of the reactor coolant system isolation valves to minimize reactor coolant loss in the.event of a rupture of a line connected to the. nuclear steam supply system, and to limit potential leakage paths from the primary containment in the event ofa, : loss-of-coolant accident.Specification:

The reactor coolant system isolation valves surveillance shall be performed as indicated below..a.. At least once per operating cycle the operable:, automatically initiated power-operated isolation valves shall be tested for automatic initiation and closure times.b. Additional surveillances shall be performed as required by. Specification 6.5.4.AMENDMENT NO.142145, 17-374-84.

197 108 LIMITING CONDITION FOR OPERATION SURVEILLANCE REQUIREMENT

c. If Specifications 3.2.7a and b above are not met, initiate normal orderly shutdown within one hour and have reactor in the cold shutdown condition within ten hours.d. Whenever fuel is in the reactor vessel and the reactor coolant temperature is less.than or equal to 2.12 0 F, the isolation valves on the shutdown cooling system lines connected to the reactor coolant system shall be operable except as specified in Specification 3.2.7.e below.e. In the event any shutdown cooling system isolation valve becomes inoperable whenever fuel is. in the reactor vessel and the reactor coolant temperature is less than or equal to 212'F, the system shall be considered operable provided that, within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, at least one valve in each line having an inoperable valve is in the mode. corresponding to the isolated condition.

f. If Specifications 3.2.7.d and 3.2.7.e above are not met, either:.(1) Immediately initiate action to suspend operations with a potential for draining the reactor vessel (OPDRVs);

or (2) Immediately initiate action to restore the valve(s)to operable status.c. At least once per quarter the feedwater and main-steam line power-operated isolation valves shall be exercised.by partial closure and* subsequent reopening.

d. At least once per plant cold shutdown the feedwater and main steam line power-operated isolation valves shall be fully closed and* reopened, unless this test has been performed within the previous.92 days..AMENDMENT NO. -142. 197 109 TABLE 3.6.2b INSTRUMENTATION THAT INITIATES PRIMARY COOLANT SYSTEM OR CONTAINMENT ISOLATION Limiting Condition for Operation Minimum No. of Operable Instrument Minimum No. Channels per of Tripped or Operable Operable Trip Systems Trip System Set Point Reactor Mode Switch Position in Which Function Must Be Operable'Parameter 0 co"=C,, 41 0.C Cu 4-'U) ~PRIMARY COOLANT ISOLATION (Main Steam, Cleanup, and Shutdown Cooling)(1) Low-Low Reactor Water Level (a) Main Steam and Cleanup 2 (b) Shutdown Cooling 2(j)2()2(00)> 5 inches (Indicator Scale)*5 inches (Indicator Scale)(i) x x x x x x (2) Manual MAIN-STEAM-LINE ISOLATION (3) High Steam Flow Main-Steam Line 2 1 x x x X 2 2(f)< 105 psid x x AMENDMENT NO. 4-42, 197 205 TABLE 3.6.2b (cont'd)INSTRUMENTATION THAT INITIATES, PRIMARY COOLANT SYSTEM OR CONTAINMENT ISOLATION Limitina Condition for Operation Minimum No.of Tripped or Operable Trip Systems Minimum No. of Operable Instrument Channels per Operable Trip System Reactor Mode Switch Position in Which Function Must Be Operable Parameter Set Point C-(I)0..1~Co CLEANUP SYSTEM ISOLATION (8) High Area Temperature SHUTDOWN COOLING SYSTEM ISOLATION (9) High Area Temperature CONTAINMENT ISOLATION 1 2(g)< 190OF.(i)x X,-.,.1 1<- 170°F (i)x x (10) Low-Low Reactor Water*2 2(f)> 5 inches (Indicator Scale)(c)x x AMENDMENT NO. 1.42, 197 207 TABLE 4.6.2b INSTRUMENTATION THAT INITIATES PRIMARY COOLANT SYSTEM OR CONTAINMENT ISOLATION Surveillance Requirement Parameter Sensor Check Instrument Channel Test Instrument Channel Calibration PRIMARY COOLANT ISOLATION (Main Steam, Cleanup and Shutdown Cooling)(1) Low-Low Reactor Water Level Once/day Once per 3 months(d)Once during each major refueling outage Once per 3 months(d)(2) Manual MAIN-STEAM-LINE ISOLATION (3) High Steam Flow Main-Steam Line Once/day Once per.3 rnonths 4 a)Once per 3 months(d)(4) Deleted (5) Low Reactor Pressure Once/day Once per 3 months(d)Once per 3 months(d)AMENDMENT NO. 142-4, 197 209 NOTES FOR TABLES 3.6.2b and 4.6.2b (g).
