All research reactors must have a special shielding around it to protect researchers from exposure. Most often this shielding is made of lead.
It is called Lead Shielding.

Shielding in a nuclear reactor refers to the materials used to contain and absorb radiation produced during nuclear reactions. These materials help protect workers and the environment from harmful radiation exposure. Common shielding materials include concrete, lead, and water.

Shielding is used to prevent the escape of neutrons from a reactor. A moderator is used in the reactor to undergo collisions with a neutron. The neutrons produced in fission collide with the molecules of the moderator, imparting their kinetic energy on them. This generates heat in the reactor. (Temperature is the measure of the average random molecular kinetic energy of a substance).
He wanted to generate power from the shielding of a nuclear reactor.
Scientists hope to achieve a sustainable and controllable fusion reaction that can generate abundant clean energy. The research on Tokamak Fusion Reactors aims to overcome the technical challenges of achieving self-sustaining fusion reactions and commercialize fusion power as a viable alternative energy source. Success in this research could help address global energy needs and reduce dependence on fossil fuels.
Nuclear reactors have a large thickness of shielding (concrete mainly) around them which reduces any radiation outside the reactor to hardly more than normal background.
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
Kamini is the Kalpakkam Mini reactor. It is used for research for the Indira Gandhi Center for Atomic Research. It is located in Kalpakkam, India and was built in October of 1996.
For shielding against radiation and to provide more safety barrier against any unexpected emergency conditions.
