Radioactive containing quantitative SSC classification method research

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 non-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. (authors)
