The nuclear power plant's cooling towers still loom over the farms and small towns that line Pennsylvania's Susquehanna River.
Microcyn arose from research done in the 1990s by Japanese physicists looking for a way to disinfect cooling water in nuclear reactors.
The drop appeared to be the result of cooling tensions over Iran's nuclear program.
After this, excavation work can start to lay the foundations of the nuclear plant including two underground 3km tunnels for the cooling water.
And have you tested in any kind of way if there was a possibility of an earthquake how would these cooling systems be able to handle shutting the nuclear reactors down?
But then at 4:00 a.m. on Mar. 28, 1979 a cooling valve got stuck at the Three Mile Island Nuclear Generating Station's Unit 2.
The massive quake knocked out cooling systems to reactors at the country's Fukushima nuclear plant.
The North Anna Power Station has two nuclear reactors and is reportedly operating on four diesel generators to maintain cooling operations.
Power has been restored to part of the cooling system at Japan's tsunami-hit Fukushima nuclear plant, after it failed for the second time in a month.
In the past month, Fukushima nuclear plant has experienced two power outages that shut down some of its cooling systems for spent fuel ponds.
The system cooling water which contained spent - but still highly radioactive - nuclear fuel rods failed and it took engineers some 30 hours to repair the damage.
David Lochbaum, the director of the Union of Concerned Scientists' Nuclear Safety Program, during a conference call Monday, questioned the safety of U.S. nuclear plants that rely on batteries to back up the power supplies for cooling systems.
About 160, 000 people had to be evacuated from the area around the nuclear plant, where meltdowns occurred at three reactors after tsunami waters knocked out cooling systems.
"No nuclear power plant has ever considered the inability to get on long-term core cooling for more than a week, much less three weeks, " Friedlander said.
The six-reactor Fukushima Daiichi nuclear plant was badly damaged after the 11 March 2011 earthquake and tsunami knocked out cooling systems to reactors, leading to meltdowns and the release of radioactivity.
Shunned by investors on Monday on fears that the nuclear crisis going on in Japan, as reactors explode and melt down after the horrendous earthquake and ensuing tsunami damaged cooling capacities, stocks from uranium miners to generator designers to plant builders have topped the charts for biggest losers.
