Activities associated with the development of nuclear reactors were carried out there before being gradually transferred to other CEA centres in the 1980’s.

The technical discussions between ASN and CEA concerning the radiological and chemical remediation of the soil of the STED continued in 2018. All the operations that can be technically achieved at a reasonably acceptable cost have been carried out. In view of the presence of residual chemical and radiological contamination, the licensee submitted a delicensing file along with a file for the establishing of active institutional controls in December 2019. ³X!z ȵǼƏȇɎ ǣȇ àƺɖȸƺɵ ٮ àȒȸȒǣɿƺ The former nuclear fuel fabrication plant in Veurey-Voroize (Isère département ), operated by Société industrielle de combustible nucléaire (SICN, Orano Group) comprised two ȇɖƬǼƺƏȸ ǣȇɀɎƏǼǼƏɎǣȒȇɀً zX ژדהژ ƏȇƳ ח ׎ِ Áǝƺ ǔɖƺǼ ǔƏƫȸǣƬƏɎǣȒȇ activities were definitively stopped in the early 2000’s.

The site presents residual contamination of the soils and the groundwater. ASN has therefore asked the licensee to submit, as a prerequisite to delicensing, an application for the implementation of active institutional controls designed to restrict the use of the soil and groundwater. The SICN submitted this file to the Isère Prefect’s Office in March 2014, and the delicensing application file for the two BNIs to ASN. A public inquiry concerning the request to implement active institutional controls was held in January 2019.
