The Dangers of Nuclear Phase-Out

Recent events have amplified the concerns surrounding nuclear energy, drawing attention to past disasters like Fukushima, Chornobyl, and the bombings of Hiroshima and Nagasaki. The ongoing conflict in Ukraine has further heightened these fears, particularly with Russia's threats involving its nuclear capabilities and the precarious situation at the Zaporizhzhia nuclear plant. This escalation has led to a renewed fear of nuclear technology, prompting many to advocate for a transition to safer energy sources. Germany has taken a leading role in this movement, finalizing its own nuclear phase-out. However, research from MIT suggests that this strategy may be ill-advised.

MIT's study investigates the implications of shutting down nuclear power plants on air quality, climate change, and public health, taking into account existing energy infrastructure and alternatives (read their paper here). The findings indicate that simply decommissioning nuclear facilities without suitable replacements could exacerbate energy shortages.

The research highlights a troubling consequence: a nuclear phase-out would likely result in greater reliance on fossil fuels, such as coal, gas, and oil. This trend arises because fossil fuel plants are relatively inexpensive to construct and can quickly ramp up production, whereas renewable energy sources have higher initial costs and more limited output capacities. Germany's experience bears this out, as the nation has increased its fossil fuel consumption to facilitate its nuclear shutdowns.

While these fossil fuels contribute significantly more pollution than nuclear energy, they also have grave implications for public health, leading to respiratory and cardiovascular diseases. Surprisingly, nuclear energy is statistically one of the safest forms of energy available today.

The MIT researchers quantified the potential health impacts of a nuclear phase-out. Their analysis revealed that if the U.S. were to shut down all its nuclear reactors, the resultant increase in emissions from fossil fuels could lead to approximately 5,200 additional deaths each year. This figure does not account for the far-reaching consequences of climate change, which can trigger hurricanes, floods, and other disasters that threaten human lives on a much larger scale.

What if the U.S. pursued a more balanced approach by replacing nuclear energy with renewable sources and low-emission fossil fuels, like natural gas with carbon capture technology? Even under this scenario, the study found that the transition would still result in around 260 deaths annually.

It's crucial to understand that transitioning from nuclear to renewables isn't as straightforward as it might seem. Although renewable energy sources tend to have lower operational costs, their high initial investment and longer construction timelines make them less practical for quick replacements of nuclear facilities. Fossil fuel plants are easier and cheaper to build and can be expanded rapidly, making them more appealing in the short term.

The data supports these concerns. For instance, death rates per 1,000 TWh of energy generated by various sources are as follows, according to Cambridge House:

• Coal: 100,000 deaths
• Oil: 36,000 deaths
• Natural Gas: 4,000 deaths
• Solar: 440 deaths
• Wind: 150 deaths
• Nuclear: 90 deaths

Remarkably, nuclear power has one of the lowest mortality rates, primarily due to its efficiency and minimal emissions. One kilogram of natural uranium can produce as much energy as 20,000 kilograms of coal, resulting in significantly less mining, transportation, and handling risks. Furthermore, advancements in technology have drastically reduced radiation emissions from nuclear plants and waste storage facilities, making them safe for surrounding communities.

Additionally, nuclear energy's carbon emissions are impressively low. According to the UNECE, carbon emissions per kWh from various energy sources are as follows:

• Coal: 1,000 g/kWh
• Oil: 263 g/kWh
• Natural Gas (no CCS): 430 g/kWh
• Solar: 15 g/kWh
• Wind: 13 g/kWh
• Nuclear: 5.1 g/kWh

It's clear that nuclear energy is among the cleanest options available. However, despite its advantages, nuclear power comprises only 4.3% of the global energy mix, while coal and oil dominate, accounting for nearly two-thirds. These fossil fuels are responsible for nearly one million deaths each year.

To put this into perspective, the ongoing Russo-Ukrainian War has resulted in approximately 364,000 total casualties, which is significantly lower than the annual death toll attributed to coal and oil.

The prospect of phasing out nuclear energy poses serious risks with far-reaching consequences. While it's understandable that nuclear power can evoke fear, the public is often misinformed about its true nature and benefits. Continuous research supports the idea that nuclear energy is one of the most viable options for protecting both the planet and public health. Thus, we should consider embracing this powerful technology rather than discarding it out of unfounded fear.
