This Chilean teenager proposes a nuclear microreactor system for Antarctica, estimates 3,254-tonne CO2 cut

A 17-year-old Chilean high school student, María Javiera Valenzuela, has proposed a hybrid energy model combining renewable sources and a next-generation nuclear microreactor to reduce diesel dependence at Antarctic research stations, according to a TOI report. Her student-led concept estimates that the system could help cut annual carbon dioxide emissions at an Antarctic base by 3,254 tonnes, though it is not an approved project.

Valenzuela developed the concept for Chile’s 2026 Antarctic School Fair, where she explored ways to address the challenges of powering research facilities in one of the world’s harshest environments.

Antarctic stations currently rely largely on diesel generators for electricity, heating and scientific operations because they provide consistent power throughout the year. However, transporting fuel to the remote continent is expensive and difficult, while diesel emissions contribute to carbon pollution and black carbon deposits that can affect snow and ice.


The student’s proposal suggests using wind turbines, solar panels and a nuclear microreactor powered by TRISO fuel as part of a single microgrid. Renewable sources would supply electricity when conditions are favourable, while the microreactor would provide backup power during periods of limited sunlight or wind.

Model estimates lower emissions at Antarctic base

According to Valenzuela’s calculations, replacing a diesel-based energy system with the proposed hybrid model could prevent around 3,254 tonnes of carbon dioxide emissions annually at a large Antarctic research station.

The estimate is based on her project modelling and would require independent evaluation. However, the concept highlights the potential of combining renewable energy with reliable backup systems to reduce fossil fuel use in polar regions.

Nuclear microreactors are designed for remote locations without access to traditional electricity grids. According to the International Atomic Energy Agency, these small reactors are intended to provide long-term power with limited refuelling requirements.

Nuclear energy proposal faces practical challenges

While the concept presents a possible solution for Antarctic energy needs, deploying nuclear technology in the region would involve several challenges. Any future reactor installation would need to meet the requirements of the Antarctic Treaty System and environmental regulations.

Issues such as transporting reactor components, maintaining safety standards, managing radioactive waste and preparing emergency response measures would also need to be addressed before any real-world application.

Student project highlights role of young innovators

Valenzuela’s proposal was created as part of Chile’s Antarctic School Fair, an initiative encouraging students to explore scientific and environmental challenges.

Although the project is not expected to be implemented in its current form, it contributes to wider discussions on sustainable energy solutions for remote locations. The concept reflects growing interest in hybrid energy systems that combine renewable sources with dependable backup technologies.
