| When Should Criticality Be Anticipated? |
|
Definition
Any Time Rods are being Withdrawn or Dilution of Boron. ie. Positive reactivity.
Only one type of positive reactivity at a time is to be made
SUR Limit is <= .4 dpm Post refuel 1dpm for all other criticalitiies |

Definition
Inverse Count Rate Ratio or 1 over M Plot.
Predicts the point of criticality based on Estimated Critical Conditions (ECC)
1. > 300pcm <400... Eval by R.E. Reactor Pwr Cont.
2. >400 <500: R.E and S.M. Permission needed for S.U.
3. >500 < 1000: ECC recal, Rods Full in. 2nd time through Permission from R.E. and S.M. needed to continue S.U. |

- CBA fully Withdrawn
- RIL Position (58 steps on CBC)
- CBB Fully Withdrawn
- CBD at 50 or 8 Fold Rod position/ .125 ICRR/ 3 Doublings
- CBD Limited to < 50 step incr.
- R.E. may recommend 25 Step Incr
- 10E-8 amps so subcritical multiplication and MTC and Dopler do not effect the NIS setpoint Data
