Speaking at the panel discussion Critical Minerals, Semiconductors, and the South Caucasus as an Investment Frontier on the sidelines of Yerevan Dialogue 2026, John Vonglis, Chairman of the Strategic Advisory Board and Executive Director for Global Government Affairs at U.S.-based Nano Nuclear Energy, outlined what he sees as a viable energy pathway for Armenia and why microreactors could become a key element of that system. He emphasized that there is no single ideal energy source and that the only workable model is a diversified energy mix. In his view, countries must rely on a combination of nuclear power, natural gas, renewables, and hydropower, using all available options to ensure stable development.
Vonglis noted that the transition to a new energy landscape cannot happen quickly, but instead requires a gradual and structured process that includes modernizing the grid and expanding infrastructure to accommodate rising demand. He pointed out that this demand is expected to grow significantly due to energy-intensive sectors such as artificial intelligence infrastructure. According to him, one of the central challenges is not only electricity generation but also the condition of transmission networks themselves. Even developed countries such as the United States face limitations in grid capacity, while for countries like Armenia the challenge is even more complex, as they must expand energy production while simultaneously enabling new industrial growth. This raises the question of how to provide stable electricity in areas where grid infrastructure is weak, limited, or entirely absent.
In this context, Vonglis suggested that microreactors could offer part of the solution. He described them as a new category of small nuclear installations that differ from both large nuclear power plants and small modular reactors. Their main advantages, he argued, lie in their autonomy, since they do not require immediate connection to a central grid, their scalability, which allows capacity to be increased incrementally, and their reliability and safety. He also highlighted their suitability for deployment in remote or hard-to-reach areas.
Nuclear microreactors are small, transportable, factory-built fission systems typically producing between 1 and 20 megawatts of electricity, making them significantly smaller than small modular reactors and far below the output of conventional nuclear plants. Their design allows them to be transported by truck, rail, or even air, enabling deployment in remote communities or industrial sites. Many concepts also feature long fuel cycles, allowing them to operate for years, and in some cases more than a decade, without refueling. In addition, they incorporate passive safety systems that do not require active human intervention, as well as advanced heat transfer technologies such as heat pipes.
Vonglis described the concept in simple terms, comparing microreactors to Lego blocks, where additional units can be added as energy demand increases. He also noted that they could replace diesel-based generation, which is often more expensive and environmentally harmful, particularly in isolated regions. At the same time, he argued that nuclear energy as a whole remains underappreciated despite being one of the cleanest and most stable sources of baseload power. In his view, the broader strategic question is whether Armenia can position itself to become part of the Western supply chain for advanced nuclear energy technologies, including reactors, fuels, and related components.
