Abstract

In the current state of maturity of severe accident (SA) codes, the time has come to foster BEPU (Best Estimate Plus Uncertainties) application in the SA domain, including Accident Management (AM). The overall objective of the EC project on “Management and Uncertainties of Severe Accidents (MUSA)”, funded in Horizon 2020 Framework Programme, is to assess the capability of SA codes when modelling reactor and SFP (Spent Fuel Pool) accident scenarios of Gen II and Gen III reactor designs. To do so, UQ (Uncertainty Quantification) methodologies are to be used, with emphasis on the effect of already-set and innovative AM measures on accident unfolding, particularly those related to ST (Source Term) mitigation. Therefore, ST related FOM (Figures Of Merit) are to be used in the UQ application. This paper synthesizes the major pillars and expectations of/from the project.
