Radioactive waste management Collecting, sorting, treating, conditioning, storing and disposing safely radioactive waste. Thematic series
Radioactive waste is generated not only by the nuclear power industry, but also by hospitals, universities and non-nuclear industries. All the regulations applying to waste in general also apply to radioactive waste. However, radioactive waste emits radiation, which makes it a particular hazard for human health and the environment. It must therefore be managed with special care, from production to final disposal. Finding suitable waste disposal solutions is a major challenge for all stakeholders, industry, regulatory authorities, public authorities, local communities and the population. Fuel assembly.

The radionuclides contained in radioactive waste may be man- made, such as caesium-137, or found in nature, such as radium-226. Containers for vitrified waste (left) and compacted waste (right). 2

L’IRSN The French Institute for Radiological Protection and Nuclear Safety (IRSN) is responsible for the scientific assessment of nuclear and radiological risk. It is an “EPIC” (a state-owned industrial and commercial enterprise) that carries out research and surveys for the French Government and the general public. It is a reference body both in France and internatio- nally, with a workforce of over 1700 people who cover a diverse range of disciplines ranging from life sciences to nuclear physics. It carries out research and assessments in the following areas of expertise: n protection of people and the environment against the risks of ionising radiation; n safety of facilities and transportation of radioactive material and its protection against malicious acts; n monitoring of nuclear materials and products that may be used in the manufacture of weapons; n emergency response. It also provides the public with information. Radioactive waste Radioactive waste is generated not only by the nuclear power industry, but also by hospitals, universities and non-nuclear industries. All the regulations applying to waste in general also apply to radioactive waste. However, radioactive waste emits radiation, which makes it a particular hazard for human health and the environment. It must therefore be managed with special care, from generation to final disposal. Finding suitable waste dispo- sal solutions is a major challenge for all stakeholders, industry, regulatory authorities, public authorities, local communities and the population.
