2. Le Vésinet (IRSN) – Cancelled

Due to an internal HR event recently scheduled for june 25 we unfortunately have to cancel this visit.

IRSN, a public entity with industrial and commercial activities, was created in 2001. The Institute is placed under the joint authority of the Ministries of Defense, Environment, Industry, Research, and Health. It is the nation’s public service expert in nuclear and radiation risks, and its activities cover all the related scientific and technical issues. Its staff is over 1,700 people.

Its areas of specialization include the environment and radiological emergency response, human radiation protection in both a medical and professional capacity, and in both normal and postaccident situations, the prevention of major accidents, nuclear reactor safety, as well as safety in nuclear plants and laboratories, transport and waste treatment, and nuclear defense and security expertise. IRSN interacts with all parties concerned by these risks (public authorities, in particular nuclear safety and security authorities, local authorities, companies, research organizations, stakeholders’ associations, etc.) to contribute to public policy issues relating to nuclear safety, human and environmental protection against ionizing radiation, and the protection of nuclear materials, facilities, and transport against the risk of malicious acts.

The Vésinet facility has been set up in the late 50s as a core component of the SCPRI (one of IRSN’s ancestors) and has been one of the main dosimetry laboratory ever since. Its tasks and projects include:

  • Dosimetry: monitoring of 170,000 workers in 17,000 companies, i.e. close to 1.5 million personal dosimeters supplied and used in the medical sector and industry.
  • Environment monitoring: radiological sampling across France thanks to dedicated monitoring networks. IRSN is also conducting research in order to expand its knowledge in the fields of dispersion and transfer or radioactive materials in atmospheric, terrestrial and marine environment.
  • Teleray Network: since 1991 this network ensures the radiological monitoring of French territory by performing a continuous measurement of gamma radiation in air thanks to about 400 probes. All measurements are automatically transferred to the centralizer located in the telemetry room on the Vésinet site.
  • Emergency Response Equipment: IRSN is in charge of setting up and maintaining mobile units (trucks, helicopter liftable containers) loaded with equipment that allows fast field screening during a radiological emergency.
