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.
期刊介绍：
Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
