Abstract: The CHASNUPP - unit 1 is a 996 MWth intermediate type pressurised water reactor that began commercial operation in May 2000 in Pakistan. The CHNUPP-1 is a conventional two loop PWR operated by the Pakistan Atomic Energy Commission (PAEC). The expected amount of radiation exposure from the CHNUPP-1 R CHNUPP - unit 1 is simulated for hypothetical severe accidents. For this purpose, modelling and simulation has been carried out in MATLAB. A kinetic model has been developed and implemented in MATLAB to carry out the simulation of the release of radionuclides. The core and coolant activity of CHNUPP-1 is compared with the similar type reactor KORI-1. The developed model uses the Origen 2.2 core inventory as a subroutine. The coolant inventory has been evaluated with 0.25% fuel damage and compared with the KORI-1 reactor.

Keywords: CHASNUPP; pressurised water reactor; loss of coolant accident.
