Which of the following parts is NOT inside the nuclear reactor in nuclear power plant?

Main Components of a Nuclear Reactor

Among the following options, Condenser is the part of the power plant’s steam cycle and is located outside the reactor. ​

1. Neutron Moderator: Moderators are used for reducing the speed of fast neutrons released from the fission reaction and making them capable of sustaining a nuclear chain reaction. Usually, water, solid graphite, and heavy water are used as a moderator in nuclear reactors.
2. Control rods: Control rods are an essential part of a nuclear reactor. They are used to control the rate of the nuclear fission reaction by absorbing neutrons. By inserting or withdrawing control rods, the reactor's power output can be regulated.
3. Fuel rods: They contain the nuclear fuel, typically uranium or plutonium, which undergoes fission to release energy. These rods are placed inside the reactor core, where the fission process generates heat, which is then used to produce steam and generate electricity.
