Scope of Syllabus
Nuclear Energy
- Nuclear fission; chain reaction; principle of operation of a nuclear reactor.
- Nuclear fusion; thermonuclear fusion as the source of the sun's energy.
Theoretical (qualitative) prediction of exothermic (with release of energy)nuclear reaction, in fusing together two light nuclei to form a heavier nucleus and in splitting heavy nucleus to form middle order (lower mass number) nuclei, is evident from the shape of BE per nucleon versus mass number graph.

Also calculate the disintegration energy Q for a heavy nucleus (A=240) with BE/A (approx = 7.6 MeV per nucleon split into two equal halves with A=120 each and BE/A (approx= 8.5 MeV/nucleon); Q (approx = 200 MeV).
Discovery of fission. Any one equation of fission reaction. Chain reaction- controlled and uncontrolled; nuclear reactor and nuclear bomb.
Main parts of a nuclear reactor including a simple diagram and their functions - fuel elements, moderator, control rods, coolant, casing; criticality; utilization of energy output - all qualitative only.

Fusion, simple example of 4H1 to 4He2 and its nuclear reaction equation; requires very high temperature (approx= 10(exp 6 degrees); difficult to achieve; hydrogen bomb; thermonuclear energy production in the sun and stars. [Details of chain reaction not required].
