Bud's Offshore Energy (BOE)

I’ll hold my opinions about nuclear power until the crisis in Japan eases. Instead, I thought I’d check on the status of offshore nuclear plant proposals.

Nuclear powered submarines date back to 1954 when the USS Nautilus was launched, and offshore nuclear plant concepts are almost as old. No such facilities have been built, but French companies are studying a subsea nuclear plant concept (see picture), and Russia has launched a floating nuclear plant prototype.

Less than a month ago, the Ecologist provided an update on the French and Russian projects. These plans will no doubt receive much more public attention as a result of the tragedy in Japan, but the French concept is quite interesting.

Pros:

Cores would be protected by three barriers: fuel cladding, reactor vessel and hull. The designers argue that immersion in sea water would ensure an infinite natural means of passive cooling and permit inherent safety and security. In addition, each plant would also be protected against potential intruders. The French argue that a submerged power plant would be less vulnerable to earthquakes, tsunamis, or floods, and would be far less vulnerable to terrorist attack.

Cons:

Sceptics are concerned that warmer water released from the reactors could be dangerous for local ecosystem. And, should there be a nuclear accident ‘the sea will be destroyed,’ according to the President of Anti-nuclear organisation Crilan, based in Cherbourg. ‘The fierce warming-up of the water will cause a massive thermal shock that will destroy sea life.’
