Where does the water go after being heated in a nuclear reactor?
Nuclear reactor heats water making steamTurbines are turned by steamCooling tower condenses spent steam back to waterwater is returned to the nuclear reactorIts actually a bit more complicated than this single closed loop, because the water heated by the nuclear reactor itself becomes slightly radioactive. Because of this radioactivity, for safety reasons a system with two closed loops connected by a heat exchanger is used. In the primary loop the water just keeps circulating between the nuclear reactor and the heat exchanger. In the secondary loop the water circulates as in the steps listed above, but substitute Heat exchanger for Nuclear reactor.
What would happen in a nuclear reactor if the coolant liquid leaked?
Short answer: Chernobyl. Physics answer: That heat has to go somewhere and it's not inclined to have a discussion about where. The heat in a fission reactor is generated by the interaction between the fuel (uranium) and the neutrons that are produced by the interaction itself. Basically, the neutrons cause the uranium atoms to break (fission). When the uranium atoms break, they release heat (nice, because we need that for things like generating electricity) and more neutrons (sort of nice, because it feeds itself). But if you don't get the heat out of there, you've got a major problem on your hands. In order to control the heat released by uranium/neutron interactions, to slow them down, nuclear reactors have "control rods" that can absorb neutrons. They're usually made of carbon. If you screw this part up, and there is no coolant, your reactor turns into the scariest heat factory you ever dreamed of. Flooding it with coolant now will result in two things: Steam explosions and radioactive coolant. If a coolant leak is all you get in this scenario, then count yourself lucky. You just avoided a complete reactor melt-down, the equivalent of an atom bomb detonating in your neighborhood.
What is the part of a nuclear power plant that undergoes a fission reaction?
The uranium 235 atoms in the nuclear fuel are what actually fission, or split into two other atoms. The uranium is in ceramic fuel pellets that are inserted into fuel rods, that make up fuel elements, that are in the reactor core that is located in the reactor vessel of the nuclear power plant. After the fuel has been in the reactor it begins to produce plutonium 239 atoms within the fuel which will also undergo a fission reaction.
How is heat generated inside a nuclear reactor?
Heat is generated inside a nuclear reactor by the release of binding energy (Strong Atomic Force) by the process of fission (splitting one atom into two) or fusion (combining two atoms into one).
How is a nuclear fission reaction controlled in a nuclear reactor?
A nuclear fission reaction is controlled in a nuclear reactor by using control rods made of materials that absorb neutrons, such as boron or cadmium. By adjusting the position of these control rods within the reactor core, the rate of fission and thus the power output can be regulated. Inserting the control rods absorbs neutrons and reduces the number available for further fission reactions, helping to maintain a steady power level.

Name two possible fuel sources for a nuclear reactor?
Uranium-235 and Plutonium-239 are two possible fuel sources for a nuclear reactor. These isotopes are fissile materials that undergo nuclear fission reactions to generate heat in a controlled manner for producing electricity.
What are the negatives about using Nuclear Energy?
This is not correct. Assuming "Using Nuclear Energy" means using it to generate electricity in a reactor. A nuclear reactor is a power plant, that uses nuclear fission to eventually generate electricity. An atom bomb also uses nuclear fission to generate energy causing an explosion. However, due to fundamental differences between the two a nuclear reactor cannot explode like an atom bomb.
How is a nuclear fission reaction controlled in nuclear reactor?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.

What do you mean by nuclear accidents and can you explain two basic types of nuclear weapons?
A nuclear accident is the unintended release of nuclear radiation into the environment, such as damage to a nuclear reactor or to a nuclear weapon (plane crash carrying nuclear bombs, etc). The two basic forms of nuclear weapons are fission and fusion weapons.
Where are two sites of nuclear power plants in Washington?
I can only find one site, Columbia Nuclear Station, 12miles NW of Richland. This is a GE Type5 reactor, rated output 1107 MWe. There was a research reactor at university in Seattle but this is being decommissioned. There are no nuclear plants in Washington DC
How is heat generated inside a nuclear reactor?

What is difference between moderator and coolant of nuclear reactor?
The control rods absorb the nuetrons which keeps the reaction rate relatively constant (rather than letting it grow exponentially). They create a situation where roughly one neutron per fission goes on to split another atom. Moderators slow down the neutrons. Fast neutrons are more inclined to bounce/deflect off of the surface of a nucleus so slower neutrons actually lead to a greater number of succesful fissions i.e. moderators don't slow the reaction down, they just help it to take place.
Introduction of nuclear fission and fission?
It is a process, in which a heavy nucleus is broken down in to two or more medium heavy fragments. It is used in nuclear reactor and atom bomb.
