NOTES FOR TABLE 3.2.C

1. For the startup and run positions of the Reactor Mode Selector Switch, there shall be two operable or tripped trip systems for each function. The SRM and IRM blocks need not be operable in "Run" mode, and the APRM and RBM rod b'ocks l need not be operable in "Startup" mode. If the first column cannot be met for one of the two trip systems, this condition may exist for up to seven days provided that during that time the operable system is functionally tested immediately and daily thereafter; If this condition lasts longer than seven days, the system shall be tripped. If the first column cannot be met for both trip systems, the systems shall be tripped.

2. W is percent of drive flow required to produce a. rated core flow of 69 Mlb/hr.

Trip level setting is in percent of design power (1998 MWt). For flows of 100% or greater, the rod block monitor maximum trip level setting shall be 107% power.

3.- IRM downscale is bypassed when it is on its lowest range.

4 This function is bypassed when the count rate is 2,100 cps.

5. One of the four SRM inputs may be bypassed.

6. This SRM function is bypassed when the IRM range switches are on range 8 or above.

7. The trip is' bypassed when the reactor power is < 30%. ,

8. This function is bypassed when tne mode switch is placed in Run.

9. If the number of operable channels is less than required by the minimum number of operable instrument channels per trip system requirement, place the inoper-able channel in the tripped condition within one hour.
