La Hague site The Orano site at La Hague is located on the north-west tip of the Cotentin peninsula, in the Manche département, 20 km west of Cherbourg and 6 km from Cap de La Hague. The site is situated about 15 kilometres from the Channel Islands. THE ORANO RECYCLAGE REPROCESSING PLANTS IN OPERATION AT LA HAGUE The La Hague plants for reprocessing fuel assemblies irradiated in nuclear reactors are operated by Orano Recyclage La Hague. Commissioning of the various units of the fuel reprocessing and waste packaging plants UP3-A (BNI 116) and UP2‑800 (BNI 117) and the Effluent Treatment Station STE3 (BNI 118) spanned from 1986 (delivery and storage of spent fuel assemblies) until 2002 (R4 plutonium reprocessing unit), with the majority of the process units being commissioned in 1989‑1990. The Decrees of 10 January 2003 set the individual reprocessing capacity of each of the two plants at 1,000 tonnes per year (t/year), in terms of the quantities of uranium and plutonium contained in the fuel assemblies before burn-up (in the reactor), and limit the total capacity of the two plants to 1,700 t/year. The limits and conditions for discharges and water intake by the site are defined by two ASN resolutions 2022-DC-0724 and 2022-DC-0725 of 16 June 2022.
