Radiological analysis of hypothetical accidents by computer

The radiological analyses of extreme hypothetical accidents were performed almost wholly by computer techniques. Major analytical codes used were RIBD, CACECO, SPRAY, HAA, and COMRADEX. This paper describes the analyses, the modeling techniques, and transition programs that edited data output from one code into a form suitable for input to another. Although not sacrificing a conservative stance, the degree of realism afforded by these analyses shows that the projected consequences could be acceptable. Furthermore the techniques which have been developed are applicable to most LMFBR accident analyses.
