According to an inside source, the maritime industry is considering the use of nuclear fuel to power commercial ships as technological advancements make such options more feasible. However, it is important to note that any potential nuclear fuel solution for ships is still at least a decade away.
The shipping industry is under increasing pressure from investors and environmentalists to find cleaner fuel alternativesas it currently accounts for nearly 3% of global CO2 emissions. Various options like ammonia, methanol, and wind have been explored, but now nuclear energy has emerged as a potential solution.
While nuclear energy has previously been used to power military submarines and icebreakers, its application in merchant ships has been limited due to cost constraints and insurers’ caution regarding coverage for ships entering commercial ports without fully understanding the risks involved.
However, a recent survey conducted by the International Chamber of Shipping Association indicated that there is growing interest in nuclear fuel compared to previous years. Some experts believe that nuclear-powered commercial ships could become viable within the next decade.
The key lies in developing small, mass-produced reactors that are less powerful and consume less nuclear fuel than traditional facilities. Italian shipbuilder Fincantieri acknowledges this development and expresses interest in following the evolution of modular nuclear reactors that can contribute significantly to decarbonizing vessels related to their core business: cruise ships, warships, and specialized vessels.
RINA, one of the world’s leading ship certification companies based in Italy, is also studying the use of nuclear fuel. They are participating in a feasibility study alongside Fincantieri and a nuclear technology company. RINA’s CEO believes that container ships requiring significant power could be among the transportation segments suitable for nuclear fuel adoption. However, he estimates it will take seven to ten years before production becomes feasible.
Despite these developments, there are several risks associated with using small reactors on ships. Questions arise regarding installation methods on board a ship and potential radiation exposure. Additionally, concerns about safeguards during ship movement, ownership issues, and the need for increased security at sea must be addressed.
In the United Kingdom, CORE POWER is working on developing an advanced molten salt nuclear reactor prototype that utilizes liquid fuel instead of solid fuel. This approach aims to eliminate the risk of coolant loss accidents, which are commonly cited as failures in conventional nuclear reactors.
CORE POWER’s CEO believes that by 2032-2035, they will be able to demonstrate their first prototype. He emphasizes that if we want a clean and green transition, nuclear energy must be part of the solution.
While the maritime industry explores these possibilities, it is crucial to consider public opinion and address concerns surrounding the use of nuclear fuel. With careful risk assessments and advancements in technology, nuclear-powered commercial ships could play a significant role in reducing emissions and achieving a more sustainable shipping industry in the future.
