One of the Biggest Challenges of Nuclear Energy Is the Disposal of Radioactive Waste. Now, an Innovative Proposal from CERN Scientists and China Could Change That Completely. The Idea Is to Use Gamma Beams to Transform Hazardous Waste into Safer Materials — while Also Generating Clean Energy.
A new proposal could change the fate of nuclear waste. Researchers from CERN and the Chinese Academy of Sciences University have presented technology that promises to transform radioactive waste into safer forms — and generate energy in the process.
The innovation was published in the scientific journal Nature and is already attracting attention for its potential to address two major problems simultaneously: the buildup of hazardous waste and the urgent need for clean energy.
The Promise of Nuclear Energy
Nuclear energy is considered one of the most efficient sources of clean electricity in the world. Currently, about 25% of the world’s carbon-free electricity comes from this type of generation.

But it has a difficult side to solve: the radioactive waste that remains dangerous for thousands of years. The so-called long-lived fission products (LLFPs) require secure storage for periods that exceed many human generations.
The accumulation of this type of waste has become a serious problem, especially for countries that heavily rely on nuclear energy to reduce carbon emissions.
The Solution: Transforming Waste into Watts
The new proposal is based on a concept called nuclear transmutation. With it, long-lived waste can be converted into more stable or short-lived elements.
The difference lies in the tool used: powerful gamma ray beams generated by CERN’s Gamma Factory.
The system, named the Advanced Nuclear Energy System (ANES), uses these rays to generate neutrons capable of initiating the transformation of the waste. This process significantly reduces the hazard of the waste while simultaneously generating thermal energy.
According to the researchers, the ANES can generate up to 500 megawatts of thermal energy. This is enough not only to keep the system itself running but also to provide additional energy.
Moreover, there is one more advantage: this method does not require the prior separation of radioactive isotopes, a costly and technically complex step. This makes the process more feasible and accessible compared to other alternatives.
Drastic Reduction of Radioactive Risk
The proposed transmutation has a direct impact on the risk time associated with nuclear waste. Instead of waiting thousands of years for them to become harmless, materials treated with the new method would have their half-life reduced to just 100 years.
This means that the waste could be stored for much shorter periods and with less risk to the environment and human health. It is an important change, with the potential to alleviate the burden on future generations.
In addition, the use of photon beams (gamma rays) is more efficient than traditional methods that use protons. These methods require more energy to operate and do not offer the same energy return during the process.
Path to Implementation
Despite the great potential, the technology is still in the development stage. Researchers claim that the proposal could become a reality within a few decades, depending on advancements in infrastructure and funding.
If adopted on a large scale, the system could help countries wishing to invest in nuclear energy without inheriting the problems of radioactive waste.
The study represents more than just a promising idea — it is a concrete step towards a cleaner future. And although the ANES system is geared towards large reactors, it reinforces an important message: it is possible to find sustainable solutions for the world’s most complex energy challenges.
