Following the global end of reliance on Russian energy supplies, countries like the Czech Republic have been contemplating the best form of energy generation that could replace the substantial supply from Mother Russia. The renewable energy sector has grown beyond expectations in recent years, and as Europe has aimed for a revival of its nuclear sector, the answer to the region’s energy problems is simple: invest more in nuclear power. In that regard, the Czech Republic has unveiled a $19 billion plan to expand its Dukovany nuclear power capacity.

The Dukovany nuclear power plant is set to receive a massive investment

The planned expansion of the Dukovany nuclear power plant is essential to replace coal in the Czech Republic, as noted by project officials. Europe overall has seen the need to revive its nuclear power capacity as the region faces the uncomfortable reality that nuclear power from Russia simply is no longer a possibility.

Geological surveys are underway at the Dukovany plant as construction is set to kick off in the near future. The plan, according to officials, is to construct two new reactors, each expected to generate more than 1,000 megawatts.

The construction of the project has been awarded to South Korea’s Korea Hydro & Nuclear Power (KHNP), and is scheduled for completion in the second half of the 2030s. The two new reactors will operate alongside the plant’s existing four reactors, which have been operational since the 1980s.

The deal with Korea Hydro & Nuclear Power includes the possibility of constructing two additional reactors at the Temelín nuclear station, which already boasts two units with a combined capacity of 2,000 MW of nuclear energy. The two facilities will supply up to 40% of the nation’s energy supply, roughly the same of what coal produces.

Government officials have noted that the expansion of the site has become a top priority as the nation aims to completely phase out cola production over the coming years.

“We cannot rely on coal any longer, and nuclear energy remains the only dependable, low-carbon source available at the scale we need.” – Petr Zavodsky, chief executive of the Dukovany expansion project

Europe’s revival of its nuclear sector has become essential as the region faces a new era of energy production

With the war in Ukraine showing no signs of ending in the near future, several European nations are contemplating a revival of the nuclear sector. The Czech Republic’s shift to nuclear power is driven by significant energy security and emission concerns.

The European Union recently classified nuclear energy as environmentally sustainable, opening the door for more European nations to shift their focus, and more importantly, their investments towards the revival of the European nuclear sector. The United States has also opted to revive its nuclear sector as the nation aims for increased energy production.

Financing for nuclear projects in the Czech Republic has been a major hurdle for nuclear energy projects. To alleviate the concerns, the Czech government has taken a more involved role in the project. The government will take an 80 per cent stake in the new plant, marking a new approach to the energy market in Europe.

The Czech Republic is aiming for nuclear to become the dominant energy resource in the nation

At the moment, nuclear power accounts for 40% of the Czech Republic’s energy portfolio, roughly the same as the coal industry. However, the government has noted its plans to increase that number to between 50% and 60%. As the United States and the Kingdom of Saudi Arabia are negotiating an agreement on civilian nuclear technology cooperation, Europe’s nuclear sector is set to become the force of energy production it was designed to be in the first place. With construction underway, the expansion of the Czech Republic’s nuclear sector is heading full steam ahead.
