The NEA Probabilistic Systems Assessment Codes User Group (PSAC) was established in early 1985 to help the development in OECD Member countries of Probabilistic Safety Assessment (PSA) codes for assessment of the performance of radioactive waste disposal systems. The activities of PSAC embrace information exchange, peer review, joint code development, discussion of topical issues and comparison of codes. The latter, which represents a major PSAC activity, provides confidence in the ability of PSA codes to represent the radioactive waste disposal systems being modelled and hence their capability to provide reliable information for safety assessments. Since December 1984, when the terms of reference of this group were first discussed, six meetings have taken place where several technical issues related to the use of stochastic assessment codes have been discussed. Two code intercomparisons were planned which constitute the object of the present lecture; Level 0 (completed), and level E (still under way). These and other actions undertaken by the group are summarised.
