The first line of shielding is to limit the neutron bombardment of the pressure vessel, to give it a safe life of 40 or more years. Then you need to protect personnel who have to go into areas close to the reactor for maintenance, and also to limit the exposure of equipment which may need maintanance done during the life of the plant

What is the radius of radiation from a nuclear reactor?
The radius of radiation from a nuclear reactor can vary depending on factors such as the reactor's power output, type of nuclear fuel used, and containment measures in place. Generally, an exclusion zone of several kilometers is established around a nuclear reactor to protect the public from potential radiation exposure.
Would the radiation from a nuclear reactor be fatal?
The radiation from a properly functioning nuclear power reactor is heavily shielded and cannot be approached close enough to be fatal. Radiation from damaged or malfunctioning nuclear power plants can be, and has been, fatal. The nuclear reactor incident at Chernobyl is one example. Nuclear reactor failures aboard ships and submarines also prove fatal but are often hidden behind national security; submarine K-19 'the widowmaker' was one such example. And of course, if one were to get into the reactor room past all of the shielding, any reactor would be fatal.
Is this true The function of control rods in a nuclear reactor is to speed up the nuclear reactions?
No, the function of the control rods is to absorb surplus neutrons so that the chain reaction proceeds at a steady rate, and to compensate for the reducing reactivity of the reactor as the fuel is burned up over the refuelling cycle. They also have a very important safety function in shutting down the reactor fully when required, by inserting them fully, thus preventing any chain reaction from starting.
What is the function of coolant in nuclear power plant?
The reactor coolant is used to extract heat from the nuclear fuel and hence maintains its integrity.
Do moderator in nuclear reactor slows down the neutrons emitted during fission?
Yes, it is the main moderator function in what is called "thermal nuclear reactors"

What is the layer of lead around the core of a nuclear reactor called?
It is called Lead Shielding.
What is the function of a nuclear reactor of a nuclear plant?
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
What is shielding in a nuclear reactor?
Shielding is the use of materials to absorb free or loose radiation, and prevent it from leaving the reactor; this would be a hazard to workers otherwise. The standard materials are concrete and lead, for their ease of use and installment, low cost and high effectiveness.
Why did Henry T Sampson create the gamma-electrical cell?
He wanted to generate power from the shielding of a nuclear reactor.

What is the primary function of fuel rods in a nuclear reactor?
The primary function of fuel rods in a nuclear reactor is to contain and control the nuclear fuel, such as uranium, that undergoes fission reactions to produce heat for generating electricity.
What is the radius of radiation from a nuclear reactor?
The radius of radiation from a nuclear reactor can vary depending on factors such as the reactor's power output, type of nuclear fuel used, and containment measures in place. Generally, an exclusion zone of several kilometers is established around a nuclear reactor to protect the public from potential radiation exposure.
What is the function of reflector and reactor core?
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
Would the radiation from a nuclear reactor be fatal?
The radiation from a properly functioning nuclear power reactor is heavily shielded and cannot be approached close enough to be fatal. Radiation from damaged or malfunctioning nuclear power plants can be, and has been, fatal. The nuclear reactor incident at Chernobyl is one example.

Why is a nuclear reactor enclosed in concrete?
For shielding against radiation and to provide more safety barrier against any unexpected emergency conditions.
