b. APRM (1) Mode switch not in-operate (2) Less than 11 LPRM 'nputs <

(3) Circuit boards not in circuit i

c. RBM (1) Mode switch not in operate '

(2) Circuit boards not in circuit i (3) RBM fails'to null j (4) Less than required number of LPRM inputs for rod selected

-l

11. During spxral unloading / reloading, the SRM count rate will be below 3 cps for some .

period of time. See Specification 3.10.B.

12. With the number of OPERABLE channels less than required by the Minimum Number of i' Operablo Instrument Channels / Trip System requirements, place the inoperabic channel in the tripped condition within one hour.

I

13. AW is the difference between two-loop and single loop effective drive flow and is  :

used for ningic recirculation loop operation. AW-0 for two recirculation loop  !

operation. '

14. One set of power referenced RBM upscale trip settings (LTSP, ITSP and llTSP) is  ;

applied based on the lowest rated MCPR limit given in Specification 3.11.C. The RBM power range setpoints control the enforcement of the appropriate upscale t rips over

- the proper core t.hermal power range as follows:

a. All RBM trips .are automatienlly bypassed below the Low Power Setpoint (LPSP). .,

L

b. The upscalc Low Trip Setpoint (LTSP) is applied at the LPSP and. up to the Intermediate Power Setpoint (IPSP).  ;
c. The upscale Intermediate Trip Setpoint (ITSP) is applied at the IPSP up to the liigh Power . Setpoint . (HPSP) .

i

d. The upscale liigh Trip Setpoint (llTSP) is applied at and above the llPSP,
15. The RBM is only required when core thermal power is 2 30% of rated power and a limiting control rod pattern (defined in Specification 3.3,B.5) exists. Requirements for operating with a limiting control rod pattern are specified in Specification 3.3.B.S.b. l
16. RBM . trip level settings are relative to the initialization referenec - i e.nal of p .100/125 of full scale which takes pince upon cantrol rod. selection. -
