A project for a submersible underwater power module, featuring two nuclear power units with a total capacity of 20 MWe, that can dive to a depth of 400 metres and provide energy in Arctic regions is being worked on by the Malakhit Marine Engineering Bureau in St Petersburg, Russia.

The Danish developer of floating Compact Molten Salt Reactors, Seaborg, has decided to change the fuel type for the initial power barges to low-enriched uranium "due to the risks associated with developing a sufficient supply of high-assay low-enriched uranium" to meet its planned timeline.

State nuclear power company Rosatom has signed an agreement with TSS Group to create a joint venture for the construction of a series of floating power units "with a capacity of at least 100 MWe and an assigned service life of up to 60 years for foreign markets and the subsequent sale of electricity from the floating power unit in the countries of presence".

More than a dozen Japanese companies have invested a combined total of about USD80 million in the UK-based Core Power, which is helping develop a floating molten salt reactor nuclear power plant and other maritime applications, according to Nikkei Asia.

Korea Hydro & Nuclear Power, Samsung Heavy Industries and Seaborg Technologies have established a consortium to develop floating nuclear power plants featuring Seaborg's compact molten salt reactor technology. 

South Korean shipbuilder Samsung Heavy Industries has completed the conceptual design for the CMSR Power Barge - a floating nuclear power plant based on compact molten salt reactors - and obtained the basic certification of the design from the American Bureau of Shipping.

The Baltic Shipyard, which builds Russia's nuclear powered icebreakers, is investing in a 50% increase of its capacity to build the vessels as well as floating nuclear power plants.

France-based testing, inspection and certification services provider Bureau Veritas has entered into an agreement with ThorCon for the technology qualification and subsequent development of a 500 MWe floating ThorCon molten salt reactor (TMSR-500) to be deployed in Indonesia.

Canada's Prodigy Clean Energy and America's NuScale have been collaborating since a 2018 Memorandum of Understanding with the "goal of bringing a competitive North American SMR marine facility to market".

Construction has started on the first of four floating nuclear power plants for the Cape Nagloynyn project that will power a huge mining development in the Russian Arctic. At a Chinese shipyard, the keel-laying ceremony was held for a barge that will later be fitted with two RITM-200S reactors.

Core Power, MIT Energy Initiative and the Idaho National Laboratory have been granted research funds by the US Department of Energy's Nuclear Energy University Program for a three-year study into the development of offshore floating nuclear power generation in the USA.

A joint study by Vietnamese power engineering consultancy PECC2, Denmark’s Seaborg, designer of power barges using compact molten salt reactors, and manufacturer Siemens Energy looked at the case for floating nuclear power plants to provide electricity as well as hydrogen and ammonia production.
