Noah Rettberg, Decouple's Germany correspondent and a skilled physics technician, dives into the potential resurgence of nuclear energy in Germany. He discusses a report that suggests Germany could reactivate its closed reactors to add significant capacity to the European grid at lower costs. The conversation touches on the evolving political landscape that embraces nuclear energy following recent geopolitical events, as well as the complexities of current nuclear laws that could enable recommissioning. Overall, it highlights a critical juncture in Germany's energy policy.
Germany could restore up to 13 gigawatts of nuclear power within eight years, leveraging existing reactors rather than constructing new ones.
The political landscape in Germany is shifting, with increasing support for nuclear energy amidst rising electricity imports and economic challenges.
Recommissioning old reactors may cost significantly less than building new ones, making it a financially viable solution for energy stability.

Comparison of Reactor Restart Costs
Germany's nuclear reactors, particularly Brockdorf and Emsland, could potentially be restarted at a fraction of the cost of constructing new reactors in Europe. While a modern reactor in Finland took about 17 years and cost around 11 billion euros to complete, restoring these German reactors may only require an investment of approximately 500 million to 1 billion euros, and could be operational in two years or less. This stark contrast underscores the economic advantages of utilizing existing infrastructure over starting new projects. Such a rapid restart could significantly contribute to stabilizing Germany's energy supply and reducing costs.
Historical Context of German Nuclear Power
Germany's journey with nuclear power began in the 1950s, evolving significantly through the 70s and 80s when nuclear energy provided up to 30% of the country’s electricity. The construction philosophy leaned towards large reactors, aiming to produce substantial amounts of power quickly, with the Biblis reactor being the largest of its time. However, following incidents like Chernobyl, public sentiment shifted dramatically against nuclear power, leading to the decision for an 'atom ausstieg,' or nuclear phase-out. Political dynamics throughout this period exacerbated the situation, with various factions vying for influence and control over energy policies.
Current Political Climate and Nuclear Energy
The current political climate in Germany reflects a growing tension around nuclear energy, especially following disruptions caused by geopolitical events like the Ukraine war. Debate has emerged about the necessity and feasibility of restarting the decommissioned reactors, with significant pressure mounting on the government to reconsider existing laws. The conservative parties are starting to take stances in favor of nuclear energy, seeking to explore an end to the phase-out. This shifting political landscape suggests a more favorable environment for the revival of nuclear energy as an option for ensuring energy stability and affordability.
Classification of Reactors for Restart
The report categorizes German reactors based on their readiness for restart, with categories ranging from those requiring minimal maintenance to those needing extensive refurbishment. Class one reactors, which can be brought back online quickly, represent around 12 gigawatts of power capacity and can be operational within a couple of years. In contrast, class two reactors will take longer and require significant repair work before they can operate again. This systematic classification aims to provide clarity on the feasibility and timeline for each reactor's return to the grid.
Economic Viability of Restarting Reactors
The economic rationale for restarting existing reactors versus building new ones is compelling, as recommissioning older reactors may cost less than 20 billion euros combined, contrasting sharply with the financial burdens of new builds like Hinkley Point. Existing infrastructure provides a pathway to rapidly increase nuclear-generated electricity without the lengthy and expensive processes associated with new construction. Decommissioning funds in Germany already accumulate to around 38 billion euros, which could support the refurbishment efforts, ensuring that shutting down these reactors prematurely is not the ideal path. Given the potential for operational upgrades and long-term sustainability, restarting these reactors stands out as a feasible and cost-effective solution for Germany's energy future.
This week,Decouple Germany correspondent Noah Rettberg, a physics laboratory technician and precision machinist, talks about the potential to restart German nuclear reactors. Anew analysis from Radiant Energy Group examines Germany's potential to redeploy nuclear power using its existing reactor fleet. Through assessment of recently shuttered reactors, their report suggests Germany could restore up to 13 gigawatts of nuclear power to the European grid within eight years – potentially at much lower costs and faster speeds than new construction. As Germany's electricity imports have risen sharply – from 9 TWh in 2023 to 25 TWh by late 2024 – and its economy faces headwinds, the country's nuclear infrastructure might offer a path forward if the political will appears.
