RISInfluence of Sump on Containment Thermal Hydraulics: Synthesis of the TOSQAN Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the course of a severe accident in a nuclear power plant, water can be collected in the sump containment through steam condensation on walls, cooling circuit leak, and by spray systems activation. Therefore, the ...
Main Parameters Influencing the Level of Labile Contamination and the Removal Factor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several nuclear facilities are currently being decommissioned in France, on CEA and EDF sites. The decommissioning process as a whole, with cutting operations and nuclear waste management presents workers with significant ...
Characterization of Incandescent Particles Emitted by a Cut Off Grinder During Decommissioning Operations for Evaluating Filter Degradation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of mechanical or thermal cutting tools when decommissioning nuclear facilities generates a lot of incandescent particles. These particles may represent a deterioration risk of the containment barriers associated ...
Assessment of Spray and Pool Scrubbing Efficiencies for Means of Mitigation Against Aerosol Dispersion in the Context of Fuel Debris Retrieval at Fukushima Daiichi: Part II
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The general context of this paper is an evaluation of strategies that can be used to mitigate aerosol dispersion during fuel debris or corium retrieval in damaged Fukushima Daiichi reactors. Knowledge of the aerosol source ...
