Russia's first floating nuclear plant, a vessel called Akademik Lomonosov, is producing electricity for the first time.

After about a decade of construction, the plant traveled 3,100 miles across the Arctic Ocean to a remote area in northern Russia in September.

It is expected provide enough electricity for around 100,000 homes.

Environmentalists have criticized the concept of nuclear plants at sea, since it could be difficult for emergency-response teams to reach them if an accident were to occur.

Russia's first floating nuclear power plant is now producing electricity in Chukotka, a remote area in the nation's Far East region.

On September 14, the Akademik Lomonosov docked in the port of Pevek, an Arctic town across from Alaska, after a 3,100-mile journey across the Arctic Ocean. Its freshly painted exterior bore the signature red, white, and blue colors of the nation's flag.

The vessel has two loaded nuclear reactors that will eventually generate enough electricity for an estimated 100,000 homes.

The plant could spur other nations to acquire floating nuclear power plants of their own, but environmentalists worry about the safety of such facilities.

Under extreme circumstances, some activists warn, an environmental disaster such as a tsunami could trigger a nuclear explosion at sea. Nuclear experts at the environmental nonprofit Greenpeace even dubbed the floating plant "Chernobyl on ice," a reference to the 1986 nuclear disaster that led to widespread contamination across Europe.
