Management and Uncertainties Of Severe Accidents (MUSA) project was founded in HORIZON 2020 EURATOM NFRP-2018 call on “Safety assessments to improve Accident Management strategies for Generation II and III reactors”. Coordinated by CIEMAT (Spain) and participated by 28 Organizations from 16 countries, MUSA overall budget is 5.768,452.50 €, more than 55% of which is contributed by the EU. The project started on June 1st, 2019 for a duration of 48 months. On July 7th, 2018, MUSA project received the NUGENIA label recognizing the excellence of the project proposal. MUSA was devised to build a harmonized approach for the analysis of uncertainties and sensitivities associated with Severe Accidents (SA) and, particularly, with the Source Term to the environment. In this regard, MUSA plans to go beyond the current state-of-the-art regarding the predictive capability of SA analysis codes by assessing/developing methodologies for their use in combination with the best available Uncertainty Quantification (UQ) tools. In order to meet such a purpose, a solid work structure has been put in place in the form of technical working packages (WP) properly coordinated. As shown in the Figure, MUSA consists of 7 WPs: WP1, MUSA COordination and project management (MUCO) led by CIEMAT; WP2, Identification and Quantification of Uncertainty Sources (IQUS) led by GRS; WP3, Review of Uncertainty Quantification Methodologies (RUQM) led by KIT; WP4, Application of UQ Methods against Integral Experiments (AUQMIE) led by ENEA; WP5, Uncertainty Quantification in Analysis and Management of Reactor Accidents (UQAMRA) led by JRC; WP6, Innovative Management of SFP Accidents (IMSFP) led by IRSN; and WP7, COmmunication and Results DISsemination (COREDIS) led by UNIPI. After more than two years, major steps have been given in the identification and quantification of uncertainty sources and the familiarization with uncertainty and sensitivity analytical tools (WP2 and WP3, respectively), and the project is fully immersed in the phase of application both in reactor (WP5) and spent fuel pools (WP6). Preceding those applications, partners have used the PHEBUS-FPT1 scenario to test their approaches for the BEPU analyses of SA (WP4) and a number of useful insights have been gained for the WP5 and WP6 applications. It is worth noting that the experiences gained in the “practical WPs” will feedback WP2 and WP3 to eventually formulate recommendations. Specific aspects of the progress made so far will be summarized in this paper.

Abstract
Management and Uncertainties Of Severe Accidents (MUSA) project was founded in HORIZON 2020 EURATOM NFRP-2018 call on “Safety assessments to improve Accident Management strategies for Generation II and III reactors”. Coordinated by CIEMAT (Spain) and participated by 28 Organizations from 16 countries, MUSA overall budget is 5.768,452.50 €, more than 55% of which is contributed by the EU. The project started on June 1st, 2019 for a duration of 48 months. On July 7th, 2018, MUSA project received the NUGENIA label recognizing the excellence of the project proposal. MUSA was devised to build a harmonized approach for the analysis of uncertainties and sensitivities associated with Severe Accidents (SA) and, particularly, with the Source Term to the environment. In this regard, MUSA plans to go beyond the current state-of-the-art regarding the predictive capability of SA analysis codes by assessing/developing methodologies for their use in combination with the best available Uncertainty Quantification (UQ) tools. In order to meet such a purpose, a solid work structure has been put in place in the form of technical working packages (WP) properly coordinated.
