SAFETY LIMITS AND LIMITING SAFETY SYSTEM SETTINGS BASES 2.2.2 CPC ADDRESSABLE CONSTANTS The Core Protection Calculator (CPC) addressable constants are provided to allow calibration of the CPC system to more accurate indications such as calorimetric measurements for power level and RCS flowrate and incore detector signals for axial flux shape, radial peaking factors and CEA deviation penalties.
Other CPC addressable constants allow penalization of the calculated DNBR and LPD values based on measurement uncertainties or inoperable equipment. Adminis trative controls on changes and periodic checking of addressable constant values (see also Technical Specifications 3.3.1 and 6.8.1) ensure that inad vertent misloading of addressable constants into the CPC's is unlikely.
