Preliminary evaluations of the environmental impact for the production of 99Mo by fusion neutrons

Dear colleagues,


It is a pleasure to announce that a new scientific paper has been published on the Focus Point  : "New Technologies for Detection, Protection, Decontamination and Developments of the Decision Support Systems in Case of CBRNe Events" that one of the 3 the special issue of SICC Series - CBRNe Conference 2020 published on the European Physics Journal Plus.

ENEA is developing an accelerator-driven 14 MeV neutron source exploiting the deuterium–tritium fusion reaction to produce 99Mo medical radioisotope as an alternative production route not based on fission reactors. It is expected that, during normal operation, a number of radionuclides, generated by means of neutron irradiation on the raw material (natural Molybdenum), will be produced and managed. The present manuscript, as foreseen by national law, discusses a hypothetical scenario to test the environmental screening models, in turn evaluating the mechanisms and parameters which affect and control the path of liquid effluents potentially released during normal operation of the facility. The aim is to estimate the amount of radioactivity to be operated and the fraction potentially discharged in this hypothetical scenario, so as to ensure that the radioactive material can be managed without any risk for the population and the environment, according to national regulations and thoroughly fulfilling the international guidelines.
