【 摘 要 】

This report documents the pedigree analysis of the MELCOR 1.8.2 code to be used for ITERs Report Preliminary on Safety. To pedigree the code the process involved four steps. The first step was taking the modified MELCOR 1.8.2 code used by the ITER Joint Central Team (JCT) for analyses in previous ITER Safety Assessments and comparing the FORTRAN code of this version line-by-line to the original 1.8.2 version of MELCOR. The second step was a nonregression analysis which involves comparing the results from the pedigreed version against those predicted by the original, unmodified version of MELCOR 1.8.2. The third step involved comparing the pedigreed version results to results from the MELCOR version used by the ITER JCT for the Generic Site Safety Report (GSSR) against a set of accident problems analyzed for the safety report. The fourth and final step involved a comparison between the pedigreed version of the code and the developmental test problems cited in the change documents referenced in this report. The results from the pedigree process are described in this report.
