-In this portion of the fuel cycle, operaiion with the given MCPR operating limits is allowed for boih normal and Tech. Spec. scram times and for both RPT oper able and inoperable.

". "These MCPR values are based on the AHF Reload Safety Analysis performed using the control rod insertion times shown below (defined as normal scram) ~ In the event that surveillance 4. 1. 3. 2 shows these scram insertion times have been exceeded, the plant thermal limits associated with normal scram times default to the values associated with Tech. Spec. scram times (3.1.3.4-p 3/4 1-7),

and the scram insertion times must meet ihe requirements of Tech. Spec.
