Germany's recent decision to close its nuclear reactors marks a significant shift in its energy policy, which previously relied heavily on nuclear power until the catastrophic Chernobyl disaster in 1986. The growing anti-nuclear sentiment was further reinforced after the Fukushima disaster in 2011, leading Germany to commit to a nuclear phaseout. The change in public opinion, especially after Russia's invasion of Ukraine, highlights concerns about energy security, which led to temporarily considering extensions of coal plant operations despite their environmental impact.

In contrast, the UK is actively expanding its nuclear energy capacity as part of its strategy to reduce carbon emissions and ensure energy security. Britain's historically favorable view towards nuclear power remains, with a significant portion of the public backing its expansion. The UK government plans to increase nuclear's share in the energy mix, emphasizing the reliability and low carbon emissions of nuclear energy amidst concerns about the safety and cost of nuclear waste disposal.

The future of nuclear is divided into two camps - heres why

Germany has closed the last of its nuclear reactors, ending the country's use of nuclear energy. Just weeks before, the UK government announced the launch of its Great British Nuclear plan, which aims to increase the share of nuclear energy as part of its total energy mix. So why are the two countries moving in different directions? German politicians were not always opposed to nuclear energy.

In the seventies, the global economy experienced an energy price shock after major oil producers imposed an embargo against the West for supporting Israel during the Yom Kippur war. As the price of oil increased, energy independence became a priority and Germany started commissioning more nuclear reactors. By the end of the 1980s, around one third of Germany's energy supply came from nuclear. Initially, opposition to nuclear was concentrated amongst student and lobbying groups who believed it was at odds with Germany's post-war pacifist stance. The Green Party, which was founded in West Germany in 1980, grew in part out of the anti-nuclear ideology and subsequent movements that followed.

Rainer Bakke is the former Germany energy state secretary. There was a small group of people who were opposing it and they had some good arguments, but the majority was on the other side. And then came the 26 April 1986. The nuclear disaster in Chernobyl, a city that was then part of the Soviet Union, was, according to the World Health Organization, the worst ever civil nuclear accident. A poorly designed experiment went catastrophically wrong, resulting in a large explosion that released waves of radioactive waste into the atmosphere. According to the official count, 31 direct deaths were associated with the disaster, but thousands are estimated to have suffered from the hazardous long-term effects of radioactivity.

It also shifted Germany's anti-nuclear stance from the fringes to the mainstream. Public opinion changed completely. We had huge majorities for a nuclear phaseout, but that did not translate into majorities in our parliament. That came only in 1998 with a change of government to a social democratic and green coalition. And at that point, we decided on the nuclear phaseout. Then the German government reached an agreement with the electric utility companies. Nuclear power stations were allowed to continue operating, but with a cap on their output and a gradual phaseout of nuclear power stations over the next two decades.

In December 2011, the German government's position on nuclear hardened further, this time after a nuclear accident in Fukushima, Japan. The incident soured the public's opinion toward nuclear energy. A few weeks after the Fukushima disaster, then German Chancellor Angela Merkel announced a major U-turn on the country's nuclear policy and decided to press ahead to close all its atomic power plants by 2022. But following Russia's invasion of Ukraine at the start of 2022, Germany considered whether to keep the last remaining reactors open longer.

German public opinion has shifted notably since the start of the war. In April that year, a survey showed that 38% of German citizens supported the nuclear phaseout. By the end of 2022, support by the end of the year had plummeted to 15%, as the country was forced to lean more on highly polluting coal-powered energy. So a compromise was reached to extend the timeline, but only by a few months, until April 2023. Arguably, coal plants are a lot more environmentally damaging than, say, using or continue to rely on nuclear energy as a power source. Why was that a more palatable option for German policymakers? Well, it was an emergency situation that we had here in Germany after the attack of Russia on Ukraine and after Mister Putin used natural gas as a weapon.

Indeed, we had to bring additional capacity to the market. And there was a very good compromise, actually, to move the end of the coal generation in Germany from 2038 up to 2030. So eight years faster than. And now for the next one or two years, some coal generators are going to run a little bit longer. This is a huge cut of emissions if you look at the whole picture. So short-term pain for long-term gain. That's the view exactly.

Germany wasn't the only country debating its use of nuclear during the energy crisis. Russia's invasion of Ukraine forced all European countries to rethink their energy security. As key gas pipelines from Russia got cut off and sanctions kicked in, it became crucial to find alternative energy sources. This meant finding new sources of natural gas, as well as pouring more money into renewables like wind and solar energy.

For the UK, the energy crisis reinforced its increasing embrace of nuclear to achieve its climate goals and ensure greater energy security. The UK's first nuclear power station was built in the 1950s. But it was Prime Minister Margaret Thatcher who, in the 1980s, proposed constructing a nuclear power station every year for a decade as part of the country's industrial strategy. While this was not achieved, public opinion to this day remains favorable.

A study in 2022 showed that almost half of Britain's 48% back the use of nuclear energy, compared to 31% who are opposed. In March 2023, the conservative British government announced that up to a quarter of the country's electricity could be generated from nuclear sources by 2050, up from 15% in 2023. Supporters of nuclear within the UK say that it produces low amounts of carbon as a power source, but it is more reliable than renewables, as it can provide a steady output 24 hours a day, seven days a week.

It is also less affected by extreme weather conditions and requires less land to operate compared to renewables. The disposal of nuclear waste remains a key risk, as radioactive waste has a long lifespan and needs to be stored safely. Crescia Jones is the nuclear safety case and licensing lead for Rolls Royce SMr. I think the public's perception of nuclear waste, nuclear, the nuclear industry...

We're the only industry that actually accounts for every single gram of our nuclear waste. It's all about how we manage it. The UK has recognized that the safest way to manage higher-level waste is by building a geological disposal facility. And this is recognized internationally as the safest way to look after our higher-level generating waste. But as I say, that's only 1% of it.

What about the risks of a catastrophic incident? Obviously, Chernobyl is the one that comes to mind and weighs on people's sentiments. Every single nuclear accident that has happened in the past, we take all that learning, and that feeds into our safety case. So we collaborate internationally with the industry. We're open, transparent, and we attend forums and conferences where we all learn and use what's our best practice.

Detractors of nuclear power also point to its huge operational and maintenance costs, often meaning that projects cannot go ahead without significant backing or subsidies from the government. Here is Simon James, senior advisor at Creep. Nuclear has very high capital requirements for construction and that can be difficult for the private sector to bear, which is why many have been built by governments. Nuclear plants, they're fairly cheap to run. The expense is in construction and decommissioning.

decommissioning costs for older reactors are quite high. That's largely because they were never designed to be taken apart. Reactors that are being designed and built now actually have a decommissioning plan already set out when they're constructed. Therefore, the decommissioning costs are much lower.

For that reason, advocates of nuclear energy say that's where small modular reactors SMRs come in. These are nuclear reactors that can be constructed easily. Crucially, decommissioning costs are paid upfront. It's a low-cost nuclear solution. We're not building massive power plants and using a large area to do it, which takes years.

As we move towards an increasingly decarbonized world, the debate about nuclear continues to rage within Europe. The European Commission aims to cut greenhouse gas emissions by at least 55% by 2030 and to be climate neutral by 2050. So a big debate emerged within European nations about whether to lean more on nuclear power as an energy source. In July 2022, the European Parliament decided to classify nuclear energy as a sustainable activity under certain conditions.

About 12% of the continent's total energy supply comes from nuclear, but the approach varies immensely from country to country. In France, for example, about 70% of the country's power is generated from nuclear energy, although many of these reactors were built in the fifties and are starting to age. Italy closed all its plants by 1990, despite producing nuclear energy in the sixties, and Spain plans to complete its nuclear phaseout by 2035.

By the time we get to 2050, right across Europe, the electricity mix will certainly be nuclear and renewables. Some countries will go for 100% renewables, some will go for a mix of renewables and nuclear, but perhaps some fossil fuels with carbon capture and storage. If that technology comes along, which it probably will on some scale. That is the energy mix we're looking at by 2050.
