A $200-Million Floating Nuclear Plant?
Roland Piquepaille writes "In 'A Floating Chernobyl?,' Popular Science reports that two Russian companies plan to build the world's first floating nuclear power plant to deliver cheap electricity to northern territories. The construction should start next year for a deployment in 2010. The huge barge will be home for two 60-megawatt nuclear reactors which will work until 2050... if everything works fine. It looks like a frightening idea, don't you think? But read more for additional details and pictures of this floating nuclear power plant."
Where else could you get an unlimited supply of coolant?
Hell, if this goes pear shaped, you could drop the core miles beneath the sea never to be seen again.

Nuclear power isn't necessarily scarier than coal or oil fired furnaces doing the same thing. The critical issues of radioactivity have largely been fixed. Pebble Bed Reactors and other self monitoring technologies also don't produce waste product like other types of reactor.

Nuclear disasters on ships waiting to happen are nothing new in that area of the world. Russia still maintains a policy of keeping nuclear waste onboard container ships in the Arctic Sea:

No.
Both the US and Russian Navy have plenty of reactors online - and many of them power ships of some kind which float in water.
And here's the kicker - they're online - right now!
Oh nosies! Call Greenpeace!
The US and Russian Navies have been doing this for 50 years! This is the first commercial venture to do it, but the military has done it safely and effectively. The US Navy has over 5500 reactor years of operations without a nulcear accident. Also, this is not the first time that power from these reactors has been put into the power grid. Any US Navy vessel that is in port and connected to shore power (which they almost always do in port) can and have provided electricity to the grid if needed. This was done in charleston after a huricane.

Will it ever be possible to have a rational discussion about energy production?
Actually you are incorrect.
The Enterprise actually has 8 reactors! The Enterprise was so expensive that the next class of carriers where not The Kitty Hawk class had four ships in it. Two of them are still in service.
What everyone is forgetting is the US did build a floating reactor into an old Liberty ship. In the late sixties it was used in Panama.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
Why is it scary?
.. not worry about whether the kids are going to burn themselves (or throw a baseball through) the solar array..
.. lets build some nuclear power plants. Use the efficient safe designs (pebble bed) and .. OHMYGOSH .. recycle the fuel. Heck, even on Slashdot they posted a story about a new tech that might make the waste that much LESS radioactive..
With all the liberal imperialist environmental communists out there screaming because
1. Coal is a non-renewable energy source.
2. Oil is a non-renewable energy source.
3. Natural gas is a non-renewable energy souce.
4. Wave power is too ugly to be built (too lazy to Google for it but Kennedy / Kerry vetoed the idea because it was too close to THEIR vacataion home).
5. Water flow (river) is too unpredictable (and causes environmental damage when you flood blah blah blah).
6. Wind power is too noisy and it kills birdies.
What the hell else do we have?
Solar? Right. Who wants a backyard full of panels? Some people like to BAR-B-QUE in their back yards
I say
= Grow a brain...
... when they see the "Made In North Korea" sticker on these reactors.
The Big-E (my boat) has 8 reactors. That's not because they thought it was a good idea, but because it was a test-bed. Their are several different reactor and steam plants (GE and Westinghouse, different versions of each) on that ship. Those 8 reactors are comparable in output to the 2 used on all the Nimitz class CVNs.
To my knowledge, all US CVNs other than the Enterprise have just 2 reactors. IIRC, subs have just the one (but I wasn't a bubblehead, so don't quote me).
OK, I am actually a Naval Officer who designs the reactors (what NUPOC was to demanding). Those are not considered Reactor Accidents. A reactor accident is defined by a failure of the fuel system that releases significant amount of radioactivity into the environment. None of the accidents that you listed are due to a failure of the core and are therfore not REACTOR ACCIDENTS!!! Get your facts straight before you post!

The USS Enterprise has 8 A2W reactors (210 MW) and Nimitz class aircraft carriers have 2 A4W reactors (194MW). So yeah, 2x60W reactors can power much less than a nuclear aircraft carrier.
From Wikipedia: http://en.wikipedia.org/wiki/SCRAM
"In modern nuclear power plants, the control rods are lifted by electric motors against both their own weight and a powerful spring. A SCRAM rapidly (less than four seconds, by test) releases the control rods from those motors and allows their weight and the spring to drive them into the reactor core, thus halting the nuclear reaction as rapidly as possible."
Also, most people are ill-informed as to why Chernobyl occured:
From Wikipedia: http://en.wikipedia.org/wiki/Void_coefficient
"A positive void coefficient means that the thermal power output increases as the void content inside the reactor increases due to increased boiling or loss of liquid moderator or coolant. If the void coefficient is large enough and control systems do not respond quickly enough, this can form a positive feedback loop which can quickly boil all the coolant in the reactor. This happened in the Chernobyl accident."
It's illegal to build positive void coefficient reactors in the US for this reason. Negative coefficient reactors won't have runaway reactions.
We're talking about TWO full scale reactors on a barge.
No, we're talking two relatively small reactors on a barge. Typical nuclear power reactors for feeding the electrical grid are in the 600 to 1000 megawatt range, not 60 MW, and most facilities have more than one (the Pickering and Darlington facilities near Toronto have 8 650 MW and 4 850 MW reactors respectively).
The reactors aboard an aircraft carrier do more than just run the lights, they can push the whole thing at speeds in excess of 40 knots (how much in excess isn't exactly talked about -- but even that is more than fast enough to water ski behind!). Ditto for nuclear subs -- plus they provide air and water for the crew (hydrolysis and reverse osmosis).
Modern nuclear submarines typically use reactors up to 200 MW, the French Rubis-class subs use a 48 MW reactor, Russia's Oskar-II class uses 2 190 MW reactors. Surface ships like aircraft carriers or the Kirov-class battle cruiser use two reactors each up to 300 MW each.

No. As you can see in these crash test videos, the containers used to transport nuclear waste can be broadsided by a 120-ton locomotive traveling at 80 miles per hour and come out of it with only cosmetic damage. Unfortumately, all the fud about accidents & terrorism on trucks or trains carrying nuclear waste tends to appeal more to peoples fearful hearts than the facts do to peoples rational minds. That makes me a sad pro-nuclear panda.
The USS Sturgis, stationed at the Panama Canal. The Department of Energy describes the Sturgis as follows: STURGIS Floating Nuclear Power Plant; Designation MH-1A, Location: Gatun Lake, Canal Zone; Principal nuclear contractor: Martin; Pressurized water reactor, Capacity: 10,000 net kW(e), Authorized 45,000 kW(t), Initial criticality, 1967; Shutdown (permanently), 1976. The vessel provided power to the Canal Zone. It was the first floating nuclear power plant and, for nearly three decades, appeared to be the last. In 2008, the Russians plan to bring on line the next floating nuclear power plant.
