The Czech Republic has chosen UK firm Rolls-Royce SMR after assessing seven potential technology suppliers for its proposed small modular reactor programme.

The Ministry of Trade said that the applicants were approached “on the basis of their potential suitability for placement in the Czech Republic … Rolls-Royce SMR emerged as the best company with which ČEZ (the Czech nuclear power company) wants to establish a strategic partnership”.

The government will now carry out a “safety assessment of the British company” as was done for those who bid for the recent large nuclear units contracts – involving the Ministry of the Interior, Security Information Service, ÚZSI, Military Intelligence and other key institutions to ensure it complies with the state’s security requirements.

The first small modular reactor (SMR) is planned by ČEZ at a site near the existing Temelin nuclear power plant in the 2030s, “before the start up of the new large Czech nuclear unit which is planned for before 2040”, the ministry said. ČEZ is also looking at other sites suitable for SMRs, including Tušimice and Dětmarovice where survey and monitoring work is taking place to see if they are suitable nuclear sites.

Prime Minister Petr Fiala said: “Small modular reactors can be a key technology for ensuring energy security in the future. That is why from the beginning we try not only to build them, but also to participate in their global production and development. In addition, the establishment of a strategic partnership between ČEZ and Rolls-Royce SMR will be a great opportunity for Czech companies that have many years of experience in the nuclear industry.”

Nuclear Power in the Czech Republic

The Czech Republic currently gets about one-third of its electricity from four VVER-440 units at Dukovany, which began operating between 1985 and 1987, and the two VVER-1000 units in operation at Temelín, which came into operation in 2000 and 2002.

In July, Korea Hydro & Nuclear Power (KHNP) was named the preferred bidder for up to four new units at the two existing nuclear power plants, with the target of the first unit entering commercial operation in 2038.

The Rolls-Royce SMR

The Rolls-Royce SMR is a 470 MWe design based on a small pressurised water reactor. It will provide consistent baseload generation for at least 60 years. 90% of the SMR – measuring about 16 metres by 4 metres – will be built in factory conditions, limiting on-site activity primarily to assembly of pre-fabricated, pre-tested, modules which significantly reduces project risk and has the potential to drastically shorten build schedules.
