A Nuclear Titanic? the First Floating Nuclear Plant

A massive floating nuclear power plant is now making its way toward its final destination at an Arctic port (April 30, 2018)… It’s the first nuclear power plant of its kind, Russian officials say.  Called the Akademik Lomonosov, the floating power plant is being towed at a creeping pace out of St. Petersburg, where it was built over the last nine years. It will eventually be brought northward, to Murmansk – where its two nuclear reactors will be loaded with nuclear fuel and started up in the fall of 2018.

From there, the power plant will be pulled to a mooring berth in the Arctic port of Pevek, in far northeast Russia. There, it will be wired into the infrastructure so it can replace an existing nuclear power installment on land.  Critics of the plan include Greenpeace, which recently warned of a “Chernobyl on ice if Russia’s plans to create a fleet of floating nuclear power stations result in a catastrophe.

Russian officials say the mandate of the Akademik Lomonoso is to supply energy to remote industrial plants and port cities, and to offshore gas and oil platforms.  “The nuclear power plant has two KLT-40S reactor units that can generate up to 70 MW of electric energy and 50 Gcal/hr of heat energy during its normal operation,” Rosatom said. “This is enough to keep the activity of the town populated with 100,000 people.”

It will take more than a year for the power plant to reach its new home port. The original plan had called for fueling the floating plant before it began that journey, at the shipyard in central St. Petersburg – but that was scuttled in the summer of 2017, after concerns were raised both in Russia and in countries along the power plant’s route through the Baltic Sea and north to the Arctic. Rosatom says it hopes the floating nuclear power plant will be online in 2019.

Floating Power Plants: the Cayman Islands

A United States company OTEC International is in talks with Caribbean Utilities Company (CUC), Grand Cayman’s electrical provider, to supply renewable energy to the island via Ocean Thermal Energy from a platform at North Side.  According to the company:

“The Cayman Islands has documented its storm history with precision, which made it easier for OTEC International to identify locations where  Floating Power Platforms (FPPs) can be securely sited and appropriately designed to survive strong storm conditions.  The first phase of the Cayman project would be the generation of 6.25-MW renewable electricity* from an FPP that would be permanently moored less than a mile from shore. At this distance from shore, the plant’s visual impact will be minimal because of the platform’s overall low profile. The power generated would be transported to a substation onshore via cable and connected to the island’s CUC grid…..A comprehensive Environmental Impact Assessment (EIA) will be completed before the project can receive all necessary licenses and permits from various governmental authorities.”

*This type of ocean-thermal electricity plant takes advantage of the temperature difference between warm surface water and cold deep seawater.
