Table 5-t is derived from the Reference 2 analyses and is valid for at! Cycle i 1 fuel types and operating domains. Table 5-1 includes treatment of these MCPR limits for SLO. Bounding MCPR values are also provided for inoperable Recirculation Pump Trip or inoperable Steam Bypass System. These two options represent the Equipment Out of Service conditions. The cycle exposure, which represents EOR, is given in the latest verified and approved Cycle Management Report or associated Engineering Change Request.
ARTS provides for power- and flow-dependent thermal limit adjustments and muftipliers, which allow fox a more reliable administration of the MCPR thermal limit. The tlow-dependent adjustment MCPR(F) is sufficiently generic to apply to ail fuel types and operating domains (References 2 and 8). In addition, there are also two sets of p o w ~ r - d e ~ ~ dMCPR e i ~ t multipliers for use with the Turbine Bypass Valves in service and TBVOOS conditions (Reference 13). Section 8.0 contains the conditions for Turbine Bypass Valve Operability. These adjustments and muhipliers are shown in Figures 5-1 through 5-3 and are referred to by Technical Specification 3.2.3. The MCPR(P) curves are independent of recirculation pump trip operability (Reference 13).

Limerick Unit 1 Cycle t l COLR COLR Limerick 1, Rev. 4 I Page 8 The ma~imumLHGR value for each fuel type for use in Technical Specification 3.2.4 is given in Table 6-1 below. The LHGR is an exposure dependent vatue. Due to the proprietary nature of these values only the maximum LHGR for each fuef type is listed in Table 6- t .
ARTS provides for power- and flow"dep~~ident thermal limit multipliers, which allow for a more reliable ad~inis~ration of the LHGR thermal limits. There are two sets of flow-dependent LGHR multipliers for duaf-loop and single-loop operation (References 2,s and 8). In addition, there are also two sets of power-dependent LHGR multipliers for use with the Turbine Bypass Valves in service and TBVOOS conditions (Reference 13). Section 8.0 contains the conditions for Turbine Bypass Valve Operability. The LHGR e r sshown in Figures 6-1 through 6 3 and are referred to by Technical Specification 3.2.4.

The LHGRFAQP) curves are independent of recirculation pump trip operabitity (Reference 13). For single loop operation, a reduction factor is used which is shown in Table 6-2 (Reference 2).
