VARIABLE OVERPOWER TRIP CONTROL METHOD OF CORE PROTECTION CALCULATOR SYSTEM

摘要

PURPOSE: A core overpower trip control method of a core protection calculation system is provided to improve stability of a core protection calculation system. CONSTITUTION: An output of an RPCS(Reactor Power Cutback System) is checked. A RSF(Rod Sharing Factor) is calculated when the RPCS is checked. A neutron flux output is calculated by reflecting the calculated RSF. A variable overpower trip set value is determined by reflecting the calculated neutron flux output value.
