How are nuclear reactors from submarines disposed of?
During the Ship / Submarine Recycling Program (SSRP), reactors are removed, sealed at both ends, and eventually shipped to the Hanford Nuclear Reservation in Washington for burial in secure trenches.
What is a light water reactor?
The nuclear fission reactors used in the United States for electric power production are classified as "light water reactors" in contrast to the "Heavy Water Reactors" used in Canada. Light water (ordinary water) is used as the moderator in U.S. reactors as well as the cooling agent and the means by which heat is removed to produce steam for turning the turbines of the electric generators.
Are nuclear power plants and nuclear medicine plants in the same building?
I don't know of any such arrangement. Medical isotopes are produced in small research type reactors where samples can be introduced into the neutron flux in reentrant tubes (commonly called thimbles) and irradiated, then quickly removed and used. Large commercial power reactors don't have these facilities.
Which is or are used in nuclear reactors to absorb neutrons?
control rods
Is the Uss enterprise going to be a museum?
No, the nuclear reactors have to be removed from the ship, which pretty much means they have to dismantle the top decks down to the engine. The only thing left worth turning into a museum would be the superstructure.
Various fields where nuclear energy is used?
It is mostly used to generate electricity, that is all large power reactors can do. There are some small reactors designed to enable samples to be irradiated and removed quickly, to provide radioisotopes for medical and industrial use.
What soviet premier installed and removed nuclear missiles in Cuba?
The General Secretary/Premier Nikita Khrushchev removed nuclear missiles from Cuba after a very tense nuclear drawdown in the U.S.
What is the difference between nuclear power plant and nuclear reactor?
It's really just a matter of degree, all reactors produce some power. Those used in a power plant will produce perhaps 3000 to 5000 Megawatts thermal. Low power reactors producing a few kilowatts are used for experiments, teaching in universities, and for producing radioisotopes by irradiating samples, but reactors in this sort of power level would not be harnessed to produce electricity, the heat produced if large enough would be removed and rejected to the atmosphere or to a water cooling circuit. This makes them simple to operate and to start and stop as required.
How many nuclear power plant are in Illinois?

Why is a nuclear reactor dangerous?
Components in the reactor inside the primary shielding will be radioactive, even after all the fuel has been removed. Provided everything is monitored and assessed properly and health physics advice followed by the operators, there should be no need for anyone to be exposed to dangerous levels during decommissioning.
Can old nuclear weapons be used to fuel nuclear reactors?
Uranium-235 and Plutonium are useful, but they would need to be mixed with non-fissile Uranium-238, to make a suitable fuel. Provided these pure substances can be extracted from the weapons, then yes, provided the required fuel manufacturing processes are set up, as the process would be different from taking natural uranium and enriching it.Weapons grade enriched Uranium-235 and Plutonium metal removed from bombs can be used directly in Fast Fission reactorslike breeder reactors, that have no moderator to slow neutrons. Such Fast Fission reactors minus the breeding blanket of Uranium or Thorium were once suggested as a way to rapidly consume the large stockpile of Plutonium from retired weapons without making more in the process. These could be considered Incinerator reactors.
What material is a control rod typically made of, and how is it utilized in nuclear reactors?
A control rod in a nuclear reactor is typically made of materials like boron, cadmium, or hafnium. These materials are used because they can absorb neutrons, which helps regulate the nuclear reaction by controlling the rate of fission. When the control rod is inserted into the reactor core, it absorbs neutrons and slows down the reaction. Conversely, when the control rod is removed, more neutrons are available to sustain the reaction and increase power output.
