Nuclear fission in a nuclear reactor is initiated by bombarding uranium or plutonium atoms with neutrons, causing them to split and release more neutrons, which then continue the chain reaction.

What starts the nuclear chain reaction in a nuclear reactor?

The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.


What is a part of a nuclear power plant that undergoes a fission reaction?

Nuclear fission takes place in the nuclear fuel rods that are placed in the reactor core that is situated in the reactor pressure vessel. The reactor pressure vessel is usually situated inside the reactor containment.


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.


Is power reactor a thermal reactor?

Yes, a power reactor is a type of thermal reactor. Power reactors use nuclear fission to produce heat, which is then used to generate electricity. The heat generated in the reactor comes from the controlled chain reaction of nuclear fission, making it a thermal reactor.


What happens in a nuclear reactor to create electricity?

In a nuclear reactor, the controlled splitting of atoms (nuclear fission) generates heat, which is used to produce steam from water. The steam then drives turbines that are connected to generators, producing electricity. The process essentially harnesses the heat energy released during nuclear fission to produce electricity.

Where does fission occour?

Nuclear fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs.


How do control rods in a nuclear reactor regulate the rate of nuclear fission?

Control rods in a nuclear reactor regulate the rate of nuclear fission by absorbing neutrons, which are needed to sustain the fission process. By adjusting the position of the control rods, operators can control the number of neutrons available to cause fission reactions, thus regulating the overall power output of the reactor.

What is the place where controlled nuclear fission reactions take place?

The place where controlled nuclear fission reactions take place is called a nuclear reactor. In a nuclear reactor, uranium atoms are split in a controlled manner to produce heat energy, which is used to generate electricity.


A nuclear reactor produces energy from uncontrolled fission?

False, the fission in nuclear reactors is controlled with the movable control rods.
