源项程序包STCP Mod 1.1开发应用

STCP Mod 1.1 AND ITS UTILIZATION

一、原项定义、研究目的及概况所谓源项就是核电厂在发生严重事故情况下从核反应堆释放至环境的放射性物质随时间变化的数量和特征。研究源项的目的是因为源项大小是电厂安全性的一个重要指标。

STCP Mod1.1 is developed by BCL for estimating the release of radioactivematerials to the environment in severa accidents of nuclear power plant. It is thestate-of-the-art version of STCP which has been released. The STCP Mod1.1 corrects a number of errors discovered in Mod1 .1. TheMod1.1 has already been successfully installed on CDC-825 computer at the IAE. Using this code package, the radionuclide release for four selected severeaccident scenarios were calculated and analysed.
