The reactor, a BN-800 built by ROSATOM ("BN" reactors have been running since 1973), shown here on a 110 foot long ocean-going barge (the gray base under the nuclear boiler), is controlled by computers to eliminate human operator errors.  It is a new generation of reactor - called "Fast-Neutron" - and is designed to run automatically and unattended for decades.  It will have to be a "Set and Forget" module, much like the hot water heater in your basement or garage.  Construction Photos .pdf

Fast-Neutron reactors, considered by many to be a substantial improvement in safety and efficiency over currently used slow-neutron nuclear reactors - if the core gets hotter than its design temperature, it looses its ability to make more even more heat.  In the author's opinion, slow reactors are also "safe enough".  Fast reactors get at least 15 times the "uranium mileage," while producing about 1/20 the nuclear waste, which decays to non-radioactive after about 200 years.  Since the oceans are 4 ppm uranium and the Japanese have a way of extracting it at several times today's street price, we will never run out.   Uranium from Seawater .pdf     Fast Reactors    Fast Reactors .mht 

Nuclear boiler modules would be mass-produced on concrete barges in the world's eight nuclear-ship capable shipyards, floated to locations next to the turbine building of any of the world's largest power plants located on navigable water (about 54% are), set on pilings (elevation adjusted for anticipated sea level changes), have a 3 foot thick reinforced concrete containment enclosure poured around it, the containment's sides covered with dirt, and finally, through a new opening in the turbine building's wall, have its steam supply pipes connected to an existing electricity generating turbine.
