LWR Safety: Current Projects

  • Development and Validation of Advanced Safety Evaluation Methods on Design Basis

    • CAMP (International Code Application and Maintenance Program of the US NRC)
      Principal aim of the international CAMP program is the validation and qualification of numeric tools for safety evaluations on generation II and III reactors. Enhancements of this tools seem to enable also safety-related evaluations on transmutation systems. KIT/INR represents within CAMP the german partners AREVA-NP Erlangen, Westinghouse/Mannheim, TÜV Süddeutschland, Technical University Munich and Gesellschaft für Anlagen- und Reaktorsicherheit (GRS). Main goal of CAMP is the further development and qualification of safety-related LWR codes like RELAP5, TRACE, PARCS und SCALE6 in an international frame.

    • NURESAFE (NUclear REactor SAFEty Simulation Platform)
      The EC-project NURESAFE is sponsored bei the 7th EC Framework Programme. Its aim is the further development of the European Nuclear Reactor Simulation Platform NURESIM. More than 20 institutions from universities, research centers, industrial companies and authorities are envolved and make contributions in the fields of neutronic, thermal-hydraulic, multi-physics, sensitivity analysis and code inegration. The KIT/INR contributions covers two work packages: SP1 (Best-estimate coupled simulation of an ATWS (Anticipated Transient without Scram) including uncertaincy analysis) and SP3 (multi-scale thermal-hydraulic analysis of BWR’s). Furthermore, KIT/INR is the leader of WP5 (Education and Training). NURESAFE was startet in January 2013 and is running until december 2015.

    • HPMC (High Performance Monte Carlo Analysis)
      The EC-Projekt HPMC aims the development and application demonstration of a hole-core Monte-Carlo calculation method for time-dependent safety analyses by means of High Performance Computing. Crusial points of the development are thermal-hydraulic feedback and consideration of burn-up. Project partners are KIT (coordination) in Germany, Delft Nuclear Consultancy (DNC) in the Netherlands, Teknologian Tutkimuskeskus (VTT) in Finland and Kunigliga Tekniska Hoegskolan (KTH) in Sweden. The project is to provide tools for reference calculations on various reactor types in order to test the accuracy of current and future deterministic analysis methods for reactor simulations. Training courses, which are part of the project, are open for all and will take place at KIT in April 2014 and at KTH in June 2014, respectively. The HPMC project is running from October 2011 until September 2104.

  • Education and Advanced Training in Nuclear Technology

    • GENTLE (Graduate and Executive Nuclear Training and Lifelong Education)
      GENTLE is a European education and training project in the field of nuclear technology. Scientists of universities and research centers, with support from industry, authorities and TSO’s, are to establish and realize lifelong advanced education programmes, which should close the lacks of the university education. The project benefits the mobility of students and Ph.D candidates and supports their exchange between the project partners in terms of courses within semester breaks as well as traineeships in industry, authorities and research centers. Furthermore, a master course, consisting of five modules is being developed. Within KIT, the institutes INR and INE contribute to this project. Students and Ph.D candidates are invited to apply to the courses, traineeships and research activities.

  • Further Development and Validation of Numeric Tools for the Evaluation of Beyond Design Accidents and Optimization of Severe Accident Management Actions

    • CESAM (Code for European Severe Accident Management)
      CESAM is a R&D project in the 7th EC Framework Programme of research and development. It started in May 2013 for duration of 4 years. It aims at the improvement of the European reference code ASTEC towards a usage in Severe Accident Management (SAM) analysis. CESAM is focused on the SAM analyses for the diverse European NPPs (PWR, VVER, CANDU) and source term evaluations. Code validation will be done in parallel vs. available or new experiments, especially relevant for SAM and for BWR (in close link with the Fukushima cases). The CESAM project is coordinated by GRS (Germany). It gathers in total 18 partners from 12 countries plus EC. INR, IKET and IAM are taking on the different work packages of CESAM (WP1: Project managemet, WP2: Validation and Assessment, WP3: Model Integration, WP4: Plant Applications, WP5: Dissemination of Knowledge). KIT/INR is in charge of WP5 and the work is focused on the validation of ASTEC using QUENCH PWR tests and on the analysis of severe accident sequences of a German Konvoi plant with ASTEC. CESAM is running from March 2013 until February 2017.

    • WASA-BOSS (Further Develoment and Application of Severe Accident Codes - Evaluation and Optimization of Severe Accident Management Actions)
      WASA-BOSS is a research network, sponsored by BMBF in the frame of the promotion concept „Basic Research Energy 2020+“. Various subprojects are carried out by universities (University Bochum, University Stuttgart, RWTH Aachen, KIT), HGF centers (HZDR Dresden, KIT) and Gesellschaft für Anlagen- und Reaktorsicherheit (GRS). The project is coordinated by RWTH Aachen. General purpose is to forward the further development and application of severe accident codes like ATHLET-CD, COCOSYS and MELCOR with respect to the evaluation und optimization of accident management actions. The subproject F, chaired by KIT/INR, is focused to the validation of ATHLET-CD on the basis of BWR specific CORA experiments. The validated code will be applicated to optimize the cooling conditions of a partly destroyed reactor core by flooding it with cold water. Based on these results, optimized severe accident management actions are to be deduced and formulated. WASA-BOSS is being carried out between March 2013 and February 2016.
