The pressuredifferencebetweenthe pressurizer transmitter and the reactor vessel midplane/beltlinewithfour reactor coolant pumps in operationis74psi.Note: These setpointsincludeanallowanceforthe 50°Fthermaltransporteffectfor heat injection transients.

A calculation has been performedtoconfirm that the setpoints will maintain the system pressure within the established limits when the pressure difference between the pressure transmitter and reactor midplane and maximum temperature/pressure instrument uncertainties are applied to the setpoints.3.2Arming Temperature COPSshallbe armedwhenanyRCScoldleg temperature is£220°F.4.0 Reactor Vessel Material Surveillance ProgramThereactor vessel material irradiation surveillance specimensshallberemovedandexaminedtodetermine changes in material properties.

The operability requirements associated with the COPS are specifiedinLCO 3.4.12 and were determined to adequately protect the RCS against brittle fracture in the eventofa cold overpressure transient in accordancewiththemethodologyspecifiedinTS5.6.6.

These setpoints and arming temperature have been developed using the NRC-approved methodology specified in TS 5.6.6.Revision 5 Vogtle Unit2-Pressure Temperature Limits Report Soutiiern Nuclear 3.1 Pressurizer PORV Setpoints The pressurizer PORV setpoints are specified in Figure 3-1 andTable3-1.Thelimitsfor the COPS setpoints are contained in the36EFPY steady-state curves(Table2-2),which are beltline conditions and are not compensated for pressure differences between the pressurizer transmitter and the reactormidplane/beltlineorforinstrument inaccuracies.

The pressure difference between the pressurizer transmitter and the reactor vessel midplane/beltlinewithfour reactor coolant pumps in operationis74psi.Note: These setpoints include an allowance for the 50°F thermal transport effect for heat injection transients.

A calculation has been performedtoconfirm that the setpoints will maintain the system pressure within the established limits when the pressure difference between the pressure transmitter and reactor midplane and maximum temperature/pressure instrument uncertainties are applied to the setpoints.3.2Arming Temperature COPSshallbe armed whenanyRCScoldleg temperatureis<220°F.4.0 Reactor Vessel Material Surveillance Program The reactor vessel material irradiation surveillance specimens shall be removed and examined to determine changes in material properties.
