104. See www.nrc.gov
look at website www.nrc.gov. This has maps and descriptions of all 104 operating reactors in the US
Then (1995) Pres. Clinton & M. Albright created the KEDO which was a way of buying North Korea Nuclear power plants circumventing US Congress & Senate approval, using mostly US tax money. Even the NY Times thought that this was a wonderful idea. They trusted a country who main export are human organs to only use the reactor for electricity to allow International inspections, promise not to further enrich anything for military nuclear weaponry. Clinton later admitted this was a mistake but they meant well. Then during Bush Hillary had the nerve to say Bush didn't know how to handle a Nuclear North Korea when it was her husband who gave the crazy Dictator the reactors!
most cannot, as to produce weapons grade plutonium the fuel cycle must be made very very short. however soviet RBMK reactors and the US hanford N reactor were designed explicitly to produce both electric power and weapons grade plutonium.
In the US, the US NRC their rule books are many tens of thousands of pages long.
"Ultimate Heas Sink" is a vitrually unlimited supply of water that can be used by nuclear reactors to cool vital systems and their primary containment during worse case (design basis) accidents. The US Nuclear Regulatory Commission requires all nuclear plants operating in the US to maintain emergency systems that can remove heat from vital systems in the event of a design basis worse case accident. Designers of nuclear reactors have determined what kind of accident would be the worse possible accident to happen, and they have designed systems to mitigate those accidents. These systems must operate independent of external sources of electricity, or other resources. These systems include (but are not limited to) emergency generators (usually diesel powered), emergency sources of pneumatics, containment structures and suppression pools capable of receiving and suppressing the energy that could be released from the reactor vessel if it ruptured. All of the systems mentioned above either generate heat, or remove heat from other systems and components . This heat must be removed in order for these systems to continue to function. Therefore, each plant must have an "Ultimate Heat Sink" capable of removing heat from the primary containment and other vital systems necessary to mitigate a worse case accident. Usually, the ultimate heat sink is a large body of water such as a river or a lake. If the water level or temperature of the "Ultimate Heat Sink" for a nuclear plant drops to a pre-defined level, or if other conditions exist to where the "Ultimate Heat Sink" cannot provide the required heat removal function, then the nuclear plant is bound by regulation to shut down. The water from the "Ultimate Heat Sink" is passed through large heat exchangers where it cools other mediums. For this reason, the water from the ultimate heat sink does not become contaminated with radioactivity from the nuclear plant.
There are 100 nuclear power reactors operating in USA besides five under construction as of July 2014.
104 operating power reactors
There are 104 commercial nuclear power reactors in the US. See the related question below.
There are 104 operating nuclear reactors in the US. See www.nrc.gov for maps and lists
I make it 104 on the NRC website (operating units, that is)
Yes, 104 operating nuclear reactors at last count
There are 104 operating nuclear reactors in the US and at least 400 world wide.
There were 104 commercial nuclear power plants operating in the United States as of 2009.
There are 104 operating reactors in the US and over 400 world-wide
Most nuclear power plants currently operating in the US are classified as pressurized water reactors (PWRs). These reactors use water as both a coolant and moderator to generate electricity through nuclear fission. PWRs are the most common type of nuclear reactor in use worldwide.
There are 104 operating power reactors in the US, and over 400 world-wide
There certainly are, 104 operating reactors I think at present. See the NRC website.
