MUSA Management and Uncertainties of Severe Accidents MUSA has - PowerPoint PPT Presentation

MUSA – Management and Uncertainties of Severe Accidents MUSA has received funding from the Euratom research and training programme 2014-2018 under grant agreement No 847441. 1

Project Description MUSA was founded in Horizon 2020 EURATOM NFRP-2018 call “ Safety assessments to on improve accident management strategies for generation II and III reactors ” . The MUSA project aims to establish a harmonised approach for the MUSA kick-off meeting in Madrid, Spain analysis of uncertainties and July 10-12, 2019 sensitivities associated with severe accident (SA) analysis among EU and non-EU entities. 2

Project Description The project was launched in June 2019. The MUSA project is coordinated by Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (CIEMAT) in Madrid, Spain. MUSA has the NUGENIA label that recognises the excellence of the project (obtained on 7 July 2018) 3

MUSA in Numbers Budget of € 5,768,452.50 48 months 16 countries 28 partners* *The MUSA project includes partnerships with non-European institutions (Canada, China, Japan, South Korea and USA). 4

Objectives & Scope The overall objective of the MUSA project is to assess the capability of SA codes when modelling reactor and Spent Fuel Pool (SFP) accident scenarios of GEN II, GEN III and GEN III+ reactor designs. o Identification of Uncertainties Quantification (UQ) methodologies to be employed, with emphasis on the effect of both existing and innovative SA Management (SAM) measures on the accident progression. o The MUSA project will determine the state-of-the-art prediction capability of SA codes & quantify the codes uncertainties applied to SA sequences. Emphasis will be made on: o SA measures (existing & innovative) o Source Term mitigation MUSA will adopt and adapt Uncertainty & Sensitivity Analysis (UaSA) methods to SA domain. 5

MUSA Approach Int-ST Uncertainties Ext-ST Uncertainties Model parameters Input parameters Nodalization Boundary conditions Numerics Accident Sequences BEPU etc. ST Uncertainties Adaptation of UQ Uncertainties database of ST Methodologies influencing parameters UQ Applications to Reactor & Recommendations for Areas for further ST SFP accident scenarios SAMG and EP researches 6

Specific Impacts A systematic assessment of the uncertainty band affecting ST in risk dominant sequences. Guidelines to systematic conduct BEPU analysis in the SA domain. A database with the characterization (upper and lower bound and pdf) of uncertainties in input deck parameters. Insights into key elements affecting SAM implementation (i.e., timing). Additional means and actions that might optimize the accident management , both in reactors and SFPs. Hands-on training & identification of major challenges . 7

Generic Expected Outcomes Close-out open issues in the SA area : uncertainties governing the Source Term (ST) estimates will be identified so that future research can reduce ST predictions uncertainties. Increase safety margins of power plants under operation (support to NPP assessments). Improve emergency response measures and SAM strategies. Enhance nuclear safety while boosting the EU safety requirements’ implementation. 10

Knowledge Dissemination MUSA education and training activities target Masters and PhD students, as well as young researchers in the ST field. o Public learning modules on MUSA major outcomes . o Mobility exchange programme under which university students and young researchers go to internship programmes. o Production of a lecture on “Uncertainty Quantification in Severe Accident Analyses” for the different international courses that might be given on Severe Accidents and/or on “uncertainties” . 11
