Refer to the Curves & Limits EOP Bases Document for a detailed discussion of the Heat Capacity Limit.
DAEC EOP BASES DOCUMENT BASES-ATWS Rev. 19 ATWS - RPV CONTROL Page 62 of 96 DISCUSSION - 2nd CRS The Heat Capacity Limit (See Graph 4) is defined to be the highest torus temperature at which initiation of RPV depressurization will not result in exceeding the Primary Containment Pressure Limit (the PCPL is 53 psig at the DAEC) before the rate of energy transfer from the RPV to the primary containment is within the capacity of the containment vent.

Control of torus temperature relative to the Heat Capacity Limit is directed in the Primary Containment Control Guideline, EOP 2. If the actions being taken in EOP 2 to preserve torus heat capacity are inadequate or not effective, RPV pressure may be reduced to provide additional margin to the Heat Capacity Limit. Full depressurization, however, may result in loss of steam-driven injection systems. RPV depressurization to mitigate primary containment challenges must therefore be coordinated with core cooling strategies. Full depressurization is appropriate only if adequate core cooling will not be sacrificed as a result. Loss of adequate core cooling would compound containment challenges and increase any resulting radioactivity release. Core cooling is thus prioritized over other EOP objectives. If, at any time during RPV depressurization, it is anticipated that continued pressure reduction will result in loss of injection flow required for adequate core cooling, the depressurization should be terminated. Pressure should be reduced as low as possible to minimize containment challenges but maintained above the maximum value at which the required injection flow can be sustained.

DAEC EOP BASES DOCUMENT BASES-ATWS Rev. 19 ATWS - RPV CONTROL Page 62 of 96 DISCUSSION - 2nd CRS The Heat Capacity Limit (See Graph 4) is defined to be the highest torus temperature at which initiation of RPV depressurization will not result in exceeding the Primary Containment Pressure Limit (the PCPL is 53 psig at the DAEC) before the rate of energy transfer from the RPV to the primary containment is within the capacity of the containment vent. Refer to the Curves & Limits EOP Bases Document for a detailed discussion of the Heat Capacity Limit.

Control of torus temperature relative to the Heat Capacity Limit is directed in the Primary Containment Control Guideline, EOP 2. If the actions being taken in EOP 2 to preserve torus heat capacity are inadequate or not effective, RPV pressure may be reduced to provide additional margin to the Heat Capacity Limit. Full depressurization, however, may result in loss of steam-driven injection systems. RPV depressurization to mitigate primary containment challenges must therefore be coordinated with core cooling strategies. Full depressurization is appropriate only if adequate core cooling will not be sacrificed as a result. Loss of adequate core cooling would compound containment challenges and increase any resulting radioactivity release. Core cooling is thus prioritized over other EOP objectives. If, at any time during RPV depressurization, it is anticipated that continued pressure reduction will result in loss of injection flow required for adequate core cooling, the depressurization should be terminated. Pressure should be reduced as low as possible to minimize containment challenges but maintained above the maximum value at which the required injection flow can be sustained.
