1. Nuclear research reactors by: group 2

2. DEFINITION Nuclear research reactors are specialized facilities designed primarily for research, development, education, and training in the field of nuclear science and technology.

3. Characteristics of nuclear reactors Their output ( neutron beams are small) They operate at lower temperatures They need far less fuel for operation,only a few kg’s of Uranium is needed to operate. They have a high power density in the core. Most of them also need a reflector to reduce neutron loss from the core.

4. Types of research reactors 1.Pool type reactor The core consisting of fuel elements and control rods immersed in an open pool of water. The water acts as a neutron moderator, cooling agent, and radiation shield.

5. Cont… 2.Tank type reactor The tank is used to house the core and coolant .

6. Cont … 3.Homogenous type reactor The reactor uses dissolved fuel in a liquid solution, usually water. In contrast, solid fuel components are employed in heterogeneous reactors.

7. Applications of nuclear reactors in ; 1.Scientific Research and Development Neutron Scattering Experiments Radioisotope production Nuclear fuel research

8. Cont … 2.Education and training Hands on experience, allows learners to observe and participate in real-time experiments. Experimental research, allows students to work on projects related to neutron activation analysis or isotope production.
