简化源项计算是由于利用大型计算机程序包完成核电厂发生各种严重事故情况下释放到环境中的放射性源项需要耗费太多计算机时间和费用而提出的一种简化处理方法。其基本思想是首先从根据放射性环境释放特点划分的各释放类中选择几个具有代表
Simplifying source term calculations is a simplified approach that takes the form of a large computer package that requires too much computer time and money to be spent on radioactive source releases to the environment in the event of serious accidents at a nuclear power plant. The basic idea is to first select a few representatives from the categories of release divided according to the release characteristics of the radioactive environment
