CLASSIFICATION OF REACTOR ACCORDING TO THEIR USE HETEROGENEOUS HOMOGENEOUS

HETEROGENEOUS REACTORS: In these reactors fuel elements is in form of rods, plates hollow

HETEROGENEOUS REACTORS: In these reactors fuel elements is in form of rods, plates hollow cylinders arranged in regular lattice pattern with moderator. HOMOGENEOUS REACTOR: IN these reactor fuel and moderator are mixed in the form of solution.

CLASSIFICATION OF REACTOR ACCORDING TO THEIR PURPOSE � RESEARCH REACTOR: To supply neutrons for

CLASSIFICATION OF REACTOR ACCORDING TO THEIR PURPOSE � RESEARCH REACTOR: To supply neutrons for research and radio active isotope manufacturing. � PRODUCTION RAECTOR: They convert fertile to fissile material. � POWER REACTORS: Utilization of fission energy produced in reactor and convert to useful power.

PRINCIPLE OF NUCLEAR FISSION REACTOR: Nuclear fission reactors are based on nuclear fission chain

PRINCIPLE OF NUCLEAR FISSION REACTOR: Nuclear fission reactors are based on nuclear fission chain reaction for a fissionable material such as 92 U 235. each fission of 92 U 235 releases 2 to 3 neutrons and energy q=2 oo Me. V.

ADVANTAGES Fuel used in nuclear fusion reactor(like deuterium) can be easily obtained from natural(ordinary)

ADVANTAGES Fuel used in nuclear fusion reactor(like deuterium) can be easily obtained from natural(ordinary) water which is present in abundant amount. � Nuclear fusion is a clean process, as it does not leave behind any harmful radio active waste after reaction has take place. � Also in nuclear fusion nuclei are lighter the energy released per unit mass is much more than corresponding quantity in nuclear fission involving heavy nuclei. �
