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.

chusnupp -1核电厂冷却剂流失事故中放射性释放量的估算

CHASNUPP - 1号机组是一座996兆瓦的中压水反应堆，于2000年5月在巴基斯坦开始商业运行。CHNUPP-1是由巴基斯坦原子能委员会(PAEC)操作的常规双环压水堆。在假设的严重事故中，模拟了CHNUPP-1 R CHNUPP-1机组的预期辐射暴露量。为此，在MATLAB中进行了建模和仿真。在MATLAB中开发并实现了一个动力学模型，对放射性核素的释放过程进行了模拟。将CHNUPP-1堆芯和冷却剂活性与KORI-1进行了比较。所开发的模型使用Origen 2.2核心库存作为子例程。该冷却剂库存以0.25%的燃料损坏进行了评估，并与KORI-1反应堆进行了比较。

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.
