摘要
本文首先通过调研国内外的各类核设施与文件体系得出结论,对于反应堆类核设施的物项分级,目前国内外都有完整的分级体系,有完备的文件体系支撑其物项分级活动;而对于非反应堆类的核设施,国内外却没有完整的分级体系,没有完备的文件体系支撑,国内仅有的由中国核工业总部发布的分级标准也存在难以应用的问题,不能够对非反应堆类核设施的物项分级提供科学与有效的指导,导致目前现有的、在建的乃至设计中的非反应堆类的核设施没有可以依据的标准,这对核安全及其评价是非常不利的。针对这样的情况我们研究出了一套放射性包容定量分级法。该方法首先以放射性包容功能为主要安全功能,分级采用定量计算的方式,根据物项所包容的放射性物质核素的种类与总活度的大小来进行级别划分。该方法引入了非缓解的概念,在考虑放射性泄露时不考虑缓解特性与缓解措施,只考虑放射性物质的量、形态、相互作用与弥散特性等因素,降低了数学模型建立的难度;另外对放射性泄露途径进行了简化与合理的取舍,只考虑放射性的人体吸入与烟云照射,利用大气弥散公式建立了通用的数学模型,提高了方法的适用性,可应用不同的核设施;采用了逆向计算思路,利用通用数学模型进行逆向计算,将后果阈值转变为源项阈值,这样可以避免了大量的重复的计算工作,降低了工作量;最后提出了量化分级准则,将物项分级过程简化为简单的三个步骤,大大提高了分级活动效率。总之该方法是一套简单、可靠、高效、实用的物项分级方法,适用于大多数非反应堆核设施的物项分级;该方法是建立在合理的假设与简化条件下完成,该法是安全的。
A kind of SSC(structures,system,and components) classification method has been studied in this paper aiming at the status that the classification standard of no reactor nuclear facility is very hard to apply.Its name is radioactive containing quantitative classification method.This method adopts the "unmitigated release" which can reduce the degree of difficulty of modeling,and then it gives a currency model which can strengthen the applicability.All the calculations are carried in a reverse process that is help to reduce the hard work,finally it shows a quantitative classification principle which can raise the efficiency.This method is a very simple,reliable,high efficiency,and practical SSC classification method,it can be applied to most of no reactor nuclear facility.
