Microreactors and the Army’s Nuclear Gamble

The US Army’s plan to install nuclear microreactors at five of its bases has sparked both excitement and concern among industry insiders, environmentalists, and safety advocates. While proponents hail these small reactors as a game-changer for energy independence, critics warn that they’ll come with significant costs – and potentially catastrophic risks.

On the surface, the Army’s decision to award $2.2 billion in contracts to five companies to build and operate microreactors appears to be a pragmatic response to the need for reliable baseload power. However, upon closer examination, it becomes clear that this move is driven by a complex mix of motivations, trade-offs, and unintended consequences.

The Army’s assertion that these reactors will provide energy independence from the grid is misleading. The United States already has 94 nuclear reactors, which supply about 19% of U.S. electricity – a figure unlikely to change anytime soon. Instead, the Army seems to be chasing a myth: that microreactors can bypass existing infrastructure and deliver clean energy directly to its bases.

Moreover, safety concerns surrounding these reactors cannot be ignored. The Army’s promise to adhere to environmental and safety regulations is reassuring, but it doesn’t address nuclear technology’s inherent risks. As Alan J. Kuperman, an associate professor at the University of Texas at Austin, notes, microreactors will come with significant costs not faced by other low-carbon energy sources.

The Army’s willingness to provide a “hidden subsidy” for nuclear companies raises questions about its role in supporting failing technologies and whether it’s justifiable to use military funds to back an industry criticized for its high costs. By awarding contracts worth billions of dollars, the Army is essentially propping up an industry that struggles to find private-sector customers for its reactors.

The issue of radioactive waste generated by these microreactors also poses a significant concern. The Army assures us that they’ll safely shut down in case of a failure, but this doesn’t address the long-term storage issue – or the risk of accidents and targeted attacks. Notably, five states have already offered to accept nuclear waste in exchange for federal support in developing nuclear energy facilities.

The Army’s push for microreactors also aligns with President Donald Trump’s executive orders aimed at accelerating nuclear power development. As part of his plan to quadruple the nation’s nuclear energy production, Trump has called on the US to build more reactors – despite the fact that only two have been built from scratch in nearly 50 years.

The Army’s decision to invest in microreactors raises questions about the future of energy policy. As the world grapples with climate change and the need for low-carbon solutions, it’s clear that nuclear power will play a limited role – at best. Meanwhile, renewable energy sources continue to gain traction, offering cleaner, more sustainable alternatives.

The Army’s gamble on microreactors may yet prove to be a costly mistake – one that could have far-reaching consequences for the nation’s energy landscape. As this story unfolds, it’s essential to remember that nuclear power is not a panacea for our energy woes. In fact, it may be just another chapter in the ongoing saga of America’s nuclear ambitions.
