One of the Safety Upgrade Programme (SUP) – Phase 2 projects was the RCS and CNT Alternative Cooling Design project. The RCS and CNT alternative cooling system with all its SSC was designed and structured in accordance with the design extension conditions (DEC) requirements specific for the Krško NPP design and site location. The RCS and CNT alternative cooling design, in combination with mobile equipment (pump, flex hoses), is considered for severe accidents. The new ARHR system meets the requirements for RCS cooling performance as the current RHR system.
