    Abstract

    The PASSAM (Passive and Active Systems on Severe Accident source term Mitigation) project has been launched in the frame of the 7th framework programme of the European Commission. Coordinated by IRSN, this four yearproject (2013 – 2016) involves nine partners from six countries having a strong experience on severe accidents: IRSN, EDF and university of Lorraine (France); CIEMAT and CSIC (Spain); PSI (Switzerland); RSE (Italy); VTT (Finland) andAREVA GmbH (Germany). It is mainly of an R&D experimental nature, aiming at studying phenomena that, under severe accident conditions, might have the potential for reducing radioactive atmospheric releases to the environment.Improvements of existing source term mitigation devices (pool scrubbing systems; sand bed filters plus metallic pre-filters), as well as innovative systems which may achieve larger source term attenuation (Acoustic agglomeration systems; High pressure spray agglomeration systems; Electric filtration systems; Improved zeolite filtration systems; Combined Filtration Systems) are studied. After two years and a half, the current status of the project is as follows. A state of the art report has been completed, allowing a precise definition of the experimental test matrices in direct link with the identified gaps ofknowledge. The experimental work is in progress and in some domains (e.g. pool scrubbing, use of zeolites for iodine trapping, combined wet and dry filtrations systems, etc…) major results have already been obtained. An open workshop mainly targeted to R&D organizations, to National Safety Authorities and their Technical Support Organizations, to utilities and to vendors, was held on February 26th, 2014 in Madrid. A second workshop will be organized at the end of the project, in December 2016 or early 2017. Simple models and/or correlations should result from in-depth analysis of PASSAM experimental results. Once implemented in severe accident analysis codes, these models should allow enhancing the capability of modelling Severe Accident Management measures and developing improved guidelines. The project’s finaloutcomes will constitute a valuable database which may be strategic for helping the utilities and regulators in assessing the performance of the existing source term mitigation systems, evaluating potential improvements of the systems anddeveloping severe accident management measures.
