Nuclear power is a way to generate energy without relying on fossil fuels like oil, coal, or gas, which produce a lot of carbon dioxide (CO2). Unlike these traditional energy sources, nuclear power doesn’t emit CO2, making it a cleaner option. However, it does produce radioactive waste that needs to be stored safely for thousands of years. Unlike wind or solar energy, nuclear power can provide electricity whenever it’s needed, making it a reliable energy source.
Some countries are exploring innovative ways to use nuclear power, such as building floating nuclear power stations. These are essentially ships equipped with nuclear reactors that can serve as mobile power plants. For example, China has started building a floating nuclear power station, and Russia has already constructed a barge with two 35-megawatt reactors. This Russian barge is expected to supply power to the remote Chukotka region.
There are safety concerns with nuclear power, especially after the Chernobyl disaster in 1986, where a reactor exploded in the former Soviet Union. This incident has led to some skepticism about floating nuclear plants, with critics calling them “Chernobyl on Ice.” However, nuclear power at sea has its benefits. Land-based nuclear plants need to be near water for cooling, which can be a challenge due to limited space and lengthy construction processes. Once built, these plants can’t be moved. In contrast, floating reactors can be relocated to where power is needed most, even in remote areas.
Building a reactor on a ship comes with its own set of challenges. The cooling system must work effectively even as the ship moves with the ocean. Containment is another issue; land-based reactors use heavy concrete structures to prevent radioactive leaks, but on a ship, this can make the vessel heavier and require a larger design.
We have a lot of experience with nuclear power at sea. The first nuclear-powered vessel, the USS Nautilus submarine, was launched in 1954. Since then, many countries have built nuclear-powered submarines and ships. The U.S. Navy has operated these vessels safely for over 50 years without any radiological accidents. The Russian Navy has faced some challenges, but safety has improved significantly since the late 1970s.
Russia currently operates several nuclear-powered icebreakers. With modern designs and years of experience, some experts believe that concerns about floating nuclear plants might be overblown. If these designs prove to be safe and effective, they could lead to more offshore nuclear reactors.
In 2015, MIT proposed a concept to combine nuclear reactors with platforms similar to those used for floating oil rigs. These platforms could be mass-produced and deployed easily, potentially lowering costs compared to land-based plants. Placing them over deep water and far from shore could also reduce risks from natural disasters like tsunamis or earthquakes. This idea is still being explored, with hopes of having operational units by 2030.
If successful, offshore nuclear power could play a significant role in combating climate change by reducing CO2 emissions and reliance on fossil fuels. However, it’s interesting to note that the Russian floating nuclear power unit is being sent to support fossil fuel extraction in a remote area.

Nuclear power is one option to reduce humanity’s dependence on fossil fuels for energy. Unlike oil, coal, or gas, generating nuclear power emits no CO2. However, it does create radioactive waste, some of which must be stored securely for thousands of years. Unlike wind or solar, nuclear power can produce energy on demand. Some countries are actively pursuing nuclear power, and some have even designed ships with reactors to serve as mobile power plants.
China is reportedly starting construction on a floating nuclear power station expected to be sea-worthy by 2021. Meanwhile, Russia has built a barge with two 35-megawatt reactors, which is anticipated to be connected to the grid in the far northeast region of Chukotka by December 2019.
There are concerns associated with nuclear power, particularly regarding safety. One of the most significant disasters in nuclear energy history occurred in the former Soviet Union in 1986 when a reactor at Chernobyl exploded. This incident has led some to criticize floating power plants, dubbing them “Chernobyl on Ice.”
However, nuclear power at sea has some advantages. Land-based power plants need to be located near water sources for cooling, which can be valuable real estate. Building on land can also involve lengthy construction processes and local opposition. Once a land-based plant is built, it cannot be relocated. In contrast, a floating reactor can be moved to a new location to supply power as needed or can provide energy to remote areas.
That said, placing a reactor on a vessel presents its own challenges. The cooling system must be designed to maintain safe temperatures even as the vessel moves with the ocean. Containment is another issue; land-based reactors can be constructed with heavy concrete containment vessels to prevent radioactive material from escaping in case of a major incident. On a floating vessel, experts note that addressing containment can increase the ship’s weight, necessitating a larger design.
Fortunately, we have significant experience with nuclear power at sea. The first nuclear-powered vessel, the submarine USS Nautilus, was launched in 1954. Since then, many militaries have built nuclear-powered submarines and surface vessels. The U.S. Navy has an excellent safety record with over 50 years of operation and no radiological accidents. The Russian Navy has faced challenges and experienced serious accidents, resulting in radiation-related fatalities. However, since the late 1970s, safety and reliability have become priorities, and their track record has improved.
Several Russian-operated nuclear-powered icebreakers are currently in service. With modern naval reactor designs and years of experience, some experts, including former Nuclear Regulatory Commission head Dale Klein, believe fears about floating nuclear plants may be exaggerated. If the design proves safe and effective, it could lead to more offshore reactor designs.
MIT proposed a concept in 2015 to combine a nuclear reactor with cylindrical platforms similar to those used for floating oil rigs. Their idea involves large platforms with nuclear reactors that could be mass-produced and deployed easily, potentially reducing costs compared to current land-based plants. Placing them over deep water and at least 13 kilometers offshore could also mitigate risks from tsunamis or earthquakes. They are still exploring this idea, hoping to have operational units by 2030.
If successful, offshore nuclear power could significantly contribute to efforts against climate change.
Lastly, while nuclear power can help reduce CO2 emissions and reliance on fossil fuels, it is noteworthy that the Russian floating nuclear power unit is being sent to a remote area to support fossil fuel extraction.
