TABLE 3.3.2-1 (Continued) r CRVICS INSTRUMENTATION TABLE NOTATIONS

1. When handling irradiated fuel in the primary or secondary containment and during CORE ALTERATIONS and operations with a potential for draining the reactor vessel.

With any control rod withdrawn. Not applicable to control rods renoved per Specification 3.9.10.1 or 3.9.10.2.

When any turbine stop valve is greater than 95% open or the reactor mode switch is in the run position.

t Main steam line isolation trip functions have 2-out-of-4 isolation logic

_ except for the main steam line flow - high trip function which has 2-out-l of-4 isolation logic for each main steam line.

l tt See Specification 3.6.4 Table 3.6.4-1 for valves which are tctuated by~

these isolation signals.

(a) A channel may be placed in an inoperable status for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for required surveillance without placing the trip system in the tripped con-dition provided at least one other OPERABLE channel in the same trip j system is monitoring that parameter.

(b) Also actuates the standby gas treatment system.

(c) Deleted (d) Also trips and isolates the mechanical vacuum pumps.

(e) Isolates RWCU valves 1G33-F001 and 1G33-F004 only.

(f) Also actuates secondary containment ventilation isolation dampers per Table 3.6.6.2-1.

(g) Manual Switch closes RWCU system inboard isolation valves F001, F028, F053, F040 and outboard isolation valves F004, F039, F034 and F054.

(h) Vacuum breaker isolation valves require RCIC system steam supply pressure low coincident with drywell pressure high for isolation of vacuum breaker isolation valves.

(i) A single manual isolation switch isolates outboard steam supply line isolation valve (F064) and the RCIC pump suction from suppression pool valve (F031) only following a manual or automatic (Reactor Vessel Water Level 2) RCIC system initiation.

(j) Only actuates secondary containment ventilation isolation dampers per Table 3.6.6.2-1. Note it is not applicable to this Trip Function.

(k) A channel may be placed in an inoperable status for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for required surveillance without placing the trip system in the trip con-dition provided that the redundant trip system is OPERABLE and monitoring that parameter.

(1) Not required to be OPERABLE when valves IVR002A,B and IVQ006A,B are sealed closed in accordance with Specification 3.6.4.

(p) Each channel consists of five temperature modules and their associated sensors. A channel is OPERABLE if and only if five temperature modules and their associated sensors are OPERABLE.
