In the licensing process for an LMFBR, the margins for safety are determined by considering many accident sequences that are within the design basis for the plant. However, to establish the safety margin beyond the design basis, also considered are accidents that have an extremely low probability of occurrence but the potential for significant consequences - such as hypothetical core-disruptive accidents (HCDAs). Assessments of the potential for HCDAs that would severely disrupt the reactor system and release radioactive material to the reactor containment (and possibly to the atmosphere) rely heavily on large-scale integrated computer codes such as SAS. The latest version of the SAS LMFBR accident analysis code, SAS4A, has recently been completed and released. One important activity which has been a part of SAS development is code validation for which a comprehensive plan has been formulated. Analysis of In Pile Experiments, mainly TREAT, form a large part of this.
