The purpose of the Centraco plant is to sort, decontaminate, reuse, treat and package –particularly by reducing their volume– waste and effluents with low levels of radioactivity. The waste resulting from the plant’s processes is then routed to Andra’s Aube respository (CSA). The facility comprises: • Ə ȅƺǼɎǣȇǕ ɖȇǣɎً ȅƺǼɎǣȇǕ Ə ȅƏɴǣȅɖȅ Ȓǔ ב ً ד ׎׎ ژ ɎȒȇȇƺɀ Ȓǔ metallic waste per year; • an incineration unit, incinerating a maximum of ב ً׎׎׎ ژ ɎȒȇȇƺɀ Ȓǔ ɀȒǼǣƳ ɯƏɀɎƺ ƏȇƳ א ً׎׎׎ ژ ɎȒȇȇƺɀ Ȓǔ ǼǣȷɖǣƳ waste per year; and • storage areas.

In 2019, the licensee submitted a facility modification request to the competent administrations (ASN, the Minister responsible for nuclear safety and the Prefect of the Gard), with a view to widening the range of waste that can be treated by the facility. The examination of this request has revealed shortcomings concerning the nature of the waste treated and consideration of the flood risk, making it necessary to revise the project.

The Malvési plant transforms the concentrates from the uranium mines into uranium tetrafluoride, which represents the first step in the fabrication of a uranium-based nuclear fuel (excluding extraction of the ore). The transformation process produces liquid effluents containing nitrated sludges loaded with natural uranium, which are decanted and evaporated in lagoons in the facility. The entire Malvesi plant is subject to the system governing Seveso high-threshold Installations Classified for Protection of the Environment.
