Assessing the production and dispersion of aerosols carrying contamination during corium laser cutting operations is IRSN's contribution to a research project undertaken jointly with ONET Technologies and CEA on behalf of the Mitsubishi Research Institute. The objective is to obtain quantified data for evaluating the risk of disseminating con-tamination when implementing this technique, over the next few years, in the process of decommissioning the dam-aged reactors at the Fukushima Dai-ichi plant.
