1. Average Planar Linear Heat Generation Rate 1.1 Technical Specification

Reference:

Sections 3.2.1 and 3.4.1.

1.2 DescriDtion

Reference 4 is used to determine the maximum average planar linear heat-generationr rate (MAPLHGR) limit for each fuel lattice in the core (GNF proprietary data). Limits listed In Reference 4 are for dual reactor recirculation loop operation (DLO). Tables 1-1 and 2 show the associated MAPLHGR multipliers (flow dependent - MAPFACF and. power dependent - MAPFACp) to be applied to the limit which are consistent with References 3 and 5.

For single reactor recirculation loop operation (SLO), the MAPLHGR limits from Reference 4 must be multiplied by the minimum of the MAPFACp, the MAPFACF, or the SLO MAPLHGR multiplier. The SLO MAPLHGR multiplier for GE10 fuel is 0.75 (Reference 5 Section 16).

The SLO MAPLHGR multiplier for GE14 fuel is 0.76 (Reference 5 Section 16).

When manual calculations are required, all MAPLHGR values for each fuel bundle type as a' _

function of the average planar exposure shall not exceed the limits as determined below:

1.2.1 During dual reactor recirculation loop operation The limits shown in Tables 1-3 through 1-7 (Reference 5) multiplied by the smaller. of either the core flow dependent MAPLHGR factor (MAPFACF) of Table 1-1, or the core'thermal power dependent MAPLHGR factor (MAPFACp) In Table 1-2.

1.2.2 During single reactor recirculation loop operation The limits shown in Tables 1-3 through 1-7 (Reference 5) multiplied by the smaller of MAPFACF. MAPFACp, or a factor of 0.75 for GE10 fuel or 0.76 for GE14 fuel (Reference 5 Section 16).

3. Linear Heat Generation Rate 3.1 Technical Specification

Reference:

Section 3.2.3. I 3.2

Description:

The linear heat generation rate (LHGR) limit is an exposure dependent value. The maximum LHGR shall not exceed the zero exposure limit of 14A kW/ft for the following fuel bundle types (Reference 6):

GE10-P8SXB353-12GZ-120T-150-T The maximum LHGR shall not exceed the zero exposure limit of 13.4 kW/ft for the following fuel bundle types (Reference 7):

GE14-Pl OSNAB353-13GZ-120T-150-T-2412 GE14-PIOSNAB354-15GZ-120T-150-T-2413 GE14-Pl OSNAB395-16GZ-120T-150-T-2519 GE14-Pl OSNAB385-16GZ-120T-150-T-2520 i_*

Due to the proprietary nature of the LHGR values, only the maximum LHGR for each fuel bundle type is shown above. The exposure dependent LHGR limit data is listed in References 6 and 8 (GNF Proprietary); the associated LHGR multipliers (LHGRFACp and LHGRFACF) can be found in Tables 3-1 and 3-2 (References 3 and 5). The LHGRFAC multipliers are the same as the MAPFAC multipliers due to the dual' protection nature (ECCS/LOCA and thermal mechanical bases) of the LHGR and MAPLHGR limits.

When manual calculations are required, all LHGR's for each fuel bundle type as a function of nodal exposure shall not exceed the limits shown In References 6 and 8 multiplied by the smaller of either the core flow dependent LHGR factor (LHGRFACF) of Table 3-1, or the core thermal power dependent LHGR factor (LHGRFACp) of Table 3-2.
