Path of Least Resistance: Clean Core’s Innovative Approach to Thorium Fuel
Milan Shah, the visionary behind Clean Core, believes that the company has uncovered a significant opportunity in the nuclear energy sector. Unlike Holtec, which has gained momentum through collaborations with large Indian industrial firms like Larsen & Toubro and Tata Consulting Engineers, Clean Core has secured its credentials by obtaining a permit sanctioned by two Atomic Energy regulators and the country’s primary state-owned nuclear entity. This regulatory backing positions Clean Core not just as a new player, but as a potential fuel vendor for existing nuclear reactors in India, capitalizing on the country’s extensive nuclear infrastructure.
A Divergent Technological Path
Clean Core’s approach contrasts sharply with both American and Chinese methodologies in the nuclear arena. Last year, China made headlines by launching its first thorium-fueled reactor, a move that reinvigorated a technology that the U.S. once pioneered but subsequently overlooked. This advancement provided China with a strategic edge in atomic energy as they venture into less familiar territory. However, the pathway to scaling this technology will necessitate the construction of entirely new reactor types, an endeavor fraught with significant costs and logistical challenges.
In this context, Milan Shah argues for a more practical and less disruptive route: “We think ours is the path of least resistance.” Instead of revolutionizing the nuclear landscape, Clean Core aims to evolve it in a manner conducive to human progress. By focusing on integrating thorium fuel into existing reactor designs, the company hopes to simplify the adoption process, which has often been hindered by the need for entirely new technologies and infrastructures.
Bridging the Reactor Gap
The company’s ambition extends beyond just pressurized heavy-water reactors (PHWRs). Within two years, Clean Core plans to engineer a thorium fuel variant suitable for light-water reactors, which dominate the U.S. nuclear fleet. This transition, however, is anything but straightforward. One of the primary challenges lies in the differing sizes of fuel rods used in PHWRs—approximately 50 centimeters long—compared to the four-meter-long rods in light-water reactors. Additionally, light-water reactors have historically struggled with neutron absorption, a critical factor in achieving fission with thorium.
This multifaceted approach is underscored by advice from Anil Kakodkar, a mentor to Shah and a former chairman of India’s Atomic Energy Commission. He notes that advancing thorium technologies could rectify negative historical narratives in India’s nuclear development timeline. After India’s controversial nuclear test in 1974—marking a pivotal moment in the landscape of global nuclear policy—it became a point of contention among neighboring countries. By focusing on thorium, India can aspire to lead in nuclear energy without evoking proliferation fears.

Global Implications of Thorium Adoption
Kakodkar posits that by promoting thorium, India could pave a path for other nations seeking to utilize nuclear energy robustly yet responsibly. “The proliferation concerns will be dismissed to a significant extent,” he asserts, claiming that this shift could lead to an accelerated expansion of nuclear power in emerging economies. The implications are profound: countries eyeing nuclear capabilities can now do so without the stigma of nuclear weapons proliferation, creating a safer global landscape for atomic energy developments.
Looking Ahead in Nuclear Energy
As Clean Core continues to carve out its niche within the nuclear energy sector, the implications of their work are manifold. Their focus on thorium represents not just a technical shift but a strategic pivot towards sustainable energy solutions that could ultimately drive decarbonization efforts globally. By leveraging existing reactor infrastructure rather than building new facilities, Clean Core’s initiatives could play a crucial role in making nuclear energy a more viable and attractive option for countries around the world.
In sum, the trajectory of Clean Core and its innovative thorium technology stands to not only redefine nuclear power but also set a precedent for how emerging nations can responsibly harness atomic energy. With increasingly collaborative approaches to energy production, the future of nuclear energy could indeed reside in paths of least resistance, leading to safer and more efficient energy landscapes.
