Technical Specification 3.5.L - Minimum Critical Power Ratio (MCPR) ;
5.2 Descriotion
- a. The MCPR Operating Limit at rated flow versus measured scram time i is shown in Figure 5.2-1. The MCPR Operating Limit is 1.34 or i greater whenever the measured 90% insertion time is 2.65 seconds '
or less. i
- b. During Manual Flow Control, the MCPR Operating Limit at reduced !
flow rates can be determined from: '
- i. Figure 5.2-2 using the appropriate flow rate, or it. The rated flow MCPR Operating Limit determined via Figure 5.2-1, whichever is greater, i
- c. During Automatic Flow Control, the MCPR Operating Limit at I reduced flow rates can be determined from Figure 5.2-3 using the appropriate flow rate and rated flow MCPR Operating Limit, which !
is obtained.from Figure 5.2-1. Linear interpolation between the !
curvas on Figure 5.2-3 is permissible.
