Common position on licensing requirements for the new VVER fuel supplies

As the diversification of fuel supplies is more and more important, the State Office for Nuclear Safety of Czech Republic (SÚJB) found the need to simplify and harmonize licensing requirements for new fuel supply across countries, which are utilizing the VVER type fuel. This led to creating a set of requirements for licensing the new fuel and followed by discussion over differences between other national approaches. The set of requirements was chosen and reviewed by the national authorities of Bulgaria, Finland, Hungary and Slovakia and their insights and comments were implemented in the text. These requirements shall be fulfilled in order to approve new fuel supplier in Temelin NPP and Dukovany NPP or any other VVER NPP. The document is based on SÚJB Safety Guide BN-JB-3.2 Design of the Pressurized Water Reactor Core and on IAEA Safety Standard No. SSR2/1, Safety of Nuclear Power Plants: Design, Specific Safety Requirements, No. SSR-2/1 (Rev. 1) together with IAEA TECDOC No. 1720, Operation and Licensing of Mixed Cores in Water Cooled Reactors.
