4 Why focusing on filtering gaseous iodine? (Cs 137, I 131, Ru 103, ) Mitigation systems within a NPP, like sprays, suppression pools, particle filters are generally characterized as regards aerosol retention efficiency in the short term, but to a far lesser extent as regards volatile iodine retention or long-term behavior. 23/07/2015 4

6 Passive and Active Systems towards enhanced Severe Accident source term Mitigation - PASSAM project Exploring potential enhancement of existing source term mitigation devices. Demonstrating the ability of innovative systems to achieve larger source term attenuation. Existing filtration systems: - Pool scrubbing systems - Sand bed filters plus metallic pre-filters Innovative filtration systems: - Accoustic agglomeration systems - Spray agglomeration systems - Electric filtration systems - Improved zeolite filtration systems - Combined filtration systems 23/07/2015 6

19 Summary and upcoming tests Observations from first tests: Results showed a strong decrease of the collection efficiency for voltages below 10 kv (negative). When the flow rate is increased at the corona vicinity, the collection efficiency is decreased. Nature of droplets solution showed its importance in the collection efficiency of I x O y particles. Wall flushing with NaOH solution allows to reach a collection efficiency of 99.9% up to 132 l/min. On-going tests: At 65 C with steam (0 vol.% steam content 70 vol.%); Varying I 2 concentrations; Testing collection efficiency on ICH 3. Long-term aims: The precipitator scale and design will have an impact on the performance of the WESP. In order to assess the collection efficiency for different size of WESP, next steps are to: Understand the phenomena which play a role in the WESP; Develop models/correlations; Try to extrapolate of developed models to accident conditions. 23/07/
