The Evolution of Nuclear Propulsion has radically transformed the way we think about space exploration. Spectacular advances have been made over the decades, but one of the most striking and discreet developments has been the integration of nuclear propulsion into our quest to understand the universe around us.

The Challenge of Interstellar Exploration

The race to conquer space has always been driven by a desire to push back the limits of science and technology. However, there are fundamental challenges to overcome in order to reach the farthest reaches of interstellar space.

The development of space nuclear propulsion has been underway for decades, but is now entering a phase where it is moving from theory to reality. NASA recently awarded a $5 million contract to Ultra Safe Nuclear Corporation (USNC) to manufacture and test advanced nuclear fuel. This marks an important transition, as nuclear propulsion moves from the design phase to the concrete development phase.

Public-Private Partnership for Space Exploration

USNC is working with Blue Origin to develop a nuclear thermal propulsion engine optimized for cislunar scientific and civil space missions, i.e. between the Earth and the Moon. This is an example of a public-private partnership designed to push back the frontiers of space exploration.

But why is nuclear propulsion so crucial to the future of space exploration? The answer lies in its ability to propel spacecraft faster and over longer distances.

The Horizons of Space Exploration

Exploring distant planets, collecting samples from asteroids, even visiting other stars are becoming attainable goals. Nuclear propulsion expands our vision of what we can achieve in space, paving the way for new scientific discoveries and a deeper understanding of the universe.

However, the integration of nuclear propulsion into space exploration is not without its challenges. Nuclear safety and waste management issues need to be carefully addressed. It is essential to ensure that these technologies are used responsibly and in line with international standards.

An exciting future

Ultimately, nuclear propulsion is transforming space exploration into an exciting reality. The future looks bright, with interstellar travel and interplanetary missions becoming increasingly accessible. The silent revolution of nuclear propulsion is bringing us a little closer to the stars, while helping us to understand our place in the universe. It’s an exciting era for space exploration, and nuclear power plays a central role in this adventure into the unknown.

Belarus commits major public investment to add a third reactor at the Ostrovets plant and initiates studies for a second nuclear site to support national energy demand.
Framatome’s accident-tolerant fuel prototype has completed a second 24-month cycle in a commercial nuclear reactor in the United States, paving the way for a third phase of industrial testing.
The Wylfa site in Wales will host three Rolls-Royce small modular reactors from 2026, marking a strategic investment in the UK’s nuclear expansion.
EDF confirmed that the Flamanville EPR has reached a major milestone, while planning a nearly year-long shutdown in 2026 for extensive regulatory inspections and key component replacement.
EDF is opening access to its long-term nuclear supply contracts to companies consuming more than 7 GWh per year, an adjustment driven by the gradual end of the Arenh mechanism.
South Korean authorities have approved the continued operation of the Kori 2 reactor for an additional eight years, marking a key milestone in the national nuclear strategy.
A public-private consortium is developing a 5 MW thermal microreactor designed to operate without refuelling for ten years, marking a strategic step in Brazil's nuclear innovation efforts.
EDF has announced that the Flamanville EPR reactor is now operating at 80% of its capacity. The target of reaching full output by the end of autumn remains confirmed by the utility.
The accelerated approval of the Aurora facility’s nuclear safety plan marks a strategic milestone in rebuilding a domestic nuclear fuel production line in the United States.
The Industrikraft consortium will invest SEK400mn ($42.2mn) to become a shareholder in Videberg Kraft, marking a new phase in Sweden’s nuclear project led by Vattenfall on the Värö Peninsula.
MVM Group has signed an agreement with Westinghouse to secure VVER-440 fuel supplies from 2028, reducing its reliance on Russia and strengthening nuclear cooperation between Budapest and Washington.
The delivery of nuclear fuel by Russian subsidiary TVEL to the Da Lat research reactor marks a key step in strengthening the nuclear commercial partnership between Moscow and Hanoi.
