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.
Yes, the sun is a nuclear fusion reactor.
Nuclear reactors are shielded using materials that absorb or block harmful radiation emitted during the nuclear reaction process. The shielding typically consists of concrete, lead, or steel to contain and reduce the amount of radiation that can escape from the reactor core. Multiple layers of shielding are used to protect workers, the environment, and surrounding areas from exposure to radiation.
The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.
The thickness of a nuclear reactor's walls can vary depending on the design and type of reactor. Generally, they are several feet thick to provide shielding against radiation and to contain any potential accidents or pressure build-up. The walls are designed to withstand high temperatures, pressure, and impacts to ensure safe operation.
The reactor vessel is the main container that houses the nuclear fuel, control rods, and coolant in a nuclear reactor. Its purpose is to contain and shield the nuclear reactions happening inside, and to provide structural support and safety for the reactor core.

It is called Lead Shielding.
He wanted to generate power from the shielding of a nuclear reactor.

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
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.
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.
For shielding against radiation and to provide more safety barrier against any unexpected emergency conditions.
A Nuclear Reactor.
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
