Framatome subsidiary Advanced Nuclear Fuels (ANF) applied in March 2022 under the Atomic Energy Act for permission to begin producing hexagonal pressurised water fuel elements under licence with TVEL, the fuel arm of Russian state nuclear corporation Rosatom. The fuel elements are to be manufactured using Russian licences and Russian technology in a joint venture with TVEL for the Eastern European market. The licence application includes some changes to some manufacturing and testing equipment and the installation of some additional equipment in existing buildings to enable the manufacture of VVER fuel elements.
The federal government had already clarified in a supervisory letter to the state that, given the current assessment by federal security authorities regarding the risk of sabotage or espionage, there was no legal basis for denying the permit.
The Lower Saxony Ministry for the Environment, Energy and Climate Protection has now announced that it has approved ANF’s application, subject to a number of conditions, as “after intensive review and inquiries, [it] had no legal grounds under the Atomic Energy Act to reject or limit the application”. The restrictions it has imposed include a general ban on entry to the facility for employees of TVEL or Rosatom, as well as persons authorised by them. Entry is only permitted in very limited cases and under the supervision of the regulatory authority.
In addition, the ministry said the hardware and software of the TVEL-licensed machines must undergo external security audits, and these machines must be data-integrated with the rest of the fuel element factory’s operational technology and information technology infrastructure. Also, the finished gadolinium fuel rods arriving from Russia must be 100% inspected for potential tampering using active and passive scanners according to the ‘four-eyes’ principle. Furthermore, ANF employees must receive regular training and awareness programmes to protect against espionage and sabotage.
Lower Saxony’s environment ministry said the approval could be revisited “if new risks are identified”, particularly in “national security”, Euractiv reported.
ANF was created in 1975 and currently employs around 400 people in Lingen. ANF fabricates fuel rods and assemblies for pressurised water reactors and boiling water reactors for customers worldwide.
In recent years, especially since the war with Ukraine began, nuclear power operators in European Union countries who had previously relied on Russian-supplied fuel have sought alternative suppliers. Nineteen VVER reactors – developed during the time of the Soviet Union and historically reliant on Russian fuel supplies – are currently in operation in the EU, including four VVER-1000 reactors in Bulgaria and the Czech Republic, and 15 VVER-440 reactors in the Czech Republic, Finland, Hungary and Slovakia.
Framatome has “a dual-track approach” to supplying fuel to VVER reactors in operation in the EU. In the short term, it will fabricate fuel identical to the proven design currently used by the reactors. In parallel, Framatome is developing and qualifying European sovereign fuels of its own design for VVER-440 and VVER-1000 reactors. The qualification of a new design requires several years within the framework of regulatory and usual certification practices, Framatome notes.
Framatome had planned to produce both VVER-1000 and VVER-440 fuel under licence from and as part of a joint venture with Rosatom at its subsidiary Advanced Nuclear Fuels in Lingen. However, it was recently reported that Framatome has now decided to produce the VVER-440 fuel at its Romans-sur-Isere fuel production site in south-east France. The company expects to submit a request to the French nuclear regulator, the Autorite de Surete Nucleaire et de Radioprotection, by the end of 2026 for approval of the changes needed at the French plant for the production of VVER-440 fuel.
