1.2 DescrioUon

The MAPLHGR Umit is the product of the Fuel-Type MAPLHGR Umit and the minimum of either the power dependent MAPLHGR Factor, MAPFACp or the flow dependent MAPLHGR Factor, MAPFACp. The Fuel-Type Maximum Average Planar Unear Heat Generation Rate (MAPLHGR) limits are determined from the tables listed below.

MAPFACp is determined from Figure 1.2-1 and MAPFACp is determined from Fi0ure 1.2-2.

Below 30% power, two VAPFACp curves are given, one for core flow greater than 50% and one for core flow equal to or less than 50%.

Reference:

Tech Spec 3.2.3.

2.2 Description.

A. Manual Flow Control MCPR Limits The Goveming MCPR Operating Limit while in Manual Flow Control is either determined from 2.2.A.1 or 2.2.A.2, whichever is greater at any given power, flow condition.

1. Power-Dependent MCPR (MCPRo}
a. Core Thermal Power 2 30%:

The MCPRp limit is the product of the full power MCPR limit (OLMCPR) as a function of T (determined from Figure 2.2-1* for the applicable operating confguration) and a power-dependent MCPR -

multiplier (Kp) (determined from Figure 2.2-3/2.2-4, Kp does not change due to EOOS confgurations).

b. Core Thermal Power 2 25%, but < 30%:

The MCPRp limit is determined from Figure 2.2-3 unless operating with EOOS, thga Figure 2.2-4 shall be used to determine the MCPRp limit. In both figures, two separate enrves are given for MCPRp, one for core flow above 50%, and oi,e for core flow equal to orless than 50%.

c. Core Thermal Power <25%:

No Thermal Limits Monitoring Required.

2. Flow-Dependent MCPR (MCPRe}

Figure 2.2-5 gives the MCPRp limit as a function of flow. The limits in this figure are applicable for all currently allowed EOOS combinations.

B. Automatic Flow Control MCPR Limits The Goveming MCPR Opeiating Limit while in Automatic Flow Control is either determined from 2.2.B.1 or 2.2.B.2, whichever is greater at any given powsi, flow condition.

1. Power-Dependent MCPR (MCPRo}

MCPRp while in Automatic Flow Control is determined from 2.2.A.1, the same as for Manual Flow Control.

jf, during Unit Coastdown, power operation exceeding the equilibrium power level is desired, th10 Figure 2.2 2 shall be used.
