Abstract: THE CONSEQUENCES OF A HYPOTHETICAL CORE DISRUPTIVE ACCIDENT (HCDA) ON A LIQUID METAL FAST BREEDER REACTOR (LMFBR) CONTAINMENT WERE ANALYZED UNDER VARIOUS ASPECTS IN A LOT OF PUBLICATIONS, NAMELY IN THE PREVIOUS SMIRT CONFERENCES. EXPERIMENTS AND ASSOCIATED CALCULATIONS PERFORMED UP TO NOW PROVIDED MUCH INFORMATION ON THE INFLUENCES OF SOME PARAMETERS OF SUCH AN ACCIDENT AND ENABLED THE VALIDATION OF THE COMPUTER CODES. MUCH HAS BEEN LEARNED ABOUT THE SENSITIVITY TO SOME PARAMETERS, BUT REFERRING ESSENTIALLY TO THE RESULTS OF EXPLOSION TESTS IN SMALL-SIZE MOCKS- UPS AND TO CALCULATIONS RELATED TO SPECIFIC CONDITIONS FOR VARIOUS REACTOR DESIGNS. A SENSITIVITY STUDY HAS BEEN UNDERTAKEN BY THE CONT WORKING GROUP (SUBGROUP OF THE FAST REACTOR SAFETY WORKING GROUP OF THE COMMISSION OF EUROPEAN COMMUNITIES). A SYNTHESIS OF A LOT OF THEORETICAL AND EXPERIMENTAL RESULTS IS PRESENTED POINTING OUT THE SENSITIVITY OF SOME SELECTED RESULTS TO IMPORTANT PARAMETERS. A SENSITIVITY STUDY IS DEFINED FOR A REAL REACTOR SIZE LAY-OUT, WHICH IS NOW IN PROGRESS; A FIRST RESULT OF THE REFERENCE CASE IS GIVEN. THE FIRST PART OF THIS PAPER PRESENTS A TENTATIVE SYNTHESIS OF THE CURRENTLY AVAILABLE THEORETICAL AND EXPERIMENTAL RESULTS SHOWING THE SENSITIVITY TO SOME PARAMETERS. THE SECOND PART DEFINES THE REACTOR LAY-OUT TO BE USED FOR THE SENSITIVITY STUDY AND GIVES PRELIMINARY RESULTS CONCERNING THE REFERENCE CASE FROM THAT STUDY.
