在法国，一些中低放废物被嵌入水硬性粘合剂中并放入混凝土罐中。它们含有  和  发射体，引起水硬性粘合剂孔隙中存在的水的辐射。这是由于辐射分解产生氢气 (H2) 的原因。 EDF R&D 和 CEA 多年来一直合作，以了解这一现象，并开发了一种名为 DO-RE-MI 的模型，该模型可以预测混凝土废物包装中氢气的产生量。使用开发的模型进行参数研究，以确定每个参数对氢气生产的影响。主要结果在本文中介绍。
In France, some of the intermediate and low level wastes are embedded in hydraulic binder and put into concrete canisters. They contain  and  emitters which cause an irradiation of water present in the pores of the hydraulic binder. This is responsible for a dihydrogen (H2) production due to radiolysis. EDF R&D and CEA have collaborated since many years in order to understand this phenomenon and develop a model called DO-RE-MI which can predict such a production of dihydrogen in concrete waste packages. A parametric study, using the developed model, was implemented in order to determine the effects of each parameter on H2 production. The main results are presented in this paper.
