1. Nuclear Physics Md. Atiqur Rahman Ahad

2. Issues to study??? Green energy? Why nuc in BD? Only energy? What are the risky areas? Hiroshima-Nagasaki? Russia’s Ch.? JP’s Fukushima? Man-made disaster vs. Natural disaster? In BD – do we have experts? Nuc. Vs. Terrorism?

3. Nuclear Engineering Nuclear Engineering is an endeavor that – makes use of radiation and radioactive material for the benefit of mankind. Like their counterparts in chemical engineering, nuclear engineers endeavor – to improve the quality of life by manipulating basic building blocks of matter.

4. Chem. vs. Nuc. Unlike chemical engineers, nuclear engineers works with reactions that produce millions of times more energy per reaction than any other known material.

5. Nuclear Energy It is free from the problems of fossil fuels: greenhouse gas emissions. A typical 1000 MW coal-burning plant emits yearly: 1,00,000 tons of SO 2 75,000 tons of NO x 5,000 tons of fly ash USA generates 20% of the electricity; it avoided in 1999 the emission of 150 million tonnes of CO 2  On the contrary, there is still the association of nuclear power with the tremendous destructive force.

6. Use of Nuc Energy Energy generation (electricity, heating) Propulsion of naval vessels Nuclear-powered spacecraft Production of radioisotopes Bomb! Medicine Agriculture

7. Some nuclear reactors

16. Power Plant: Heat  Steam  Generator  Electricity Power plants use heat supplied by a fuel to boil water and make steam, which drives a generator to make electricity. A generating plant's fuel: – coal, gas, oil, uranium, solar thermal Fuel heats water & turns it into steam. The pressure of the steam spins the blades of a giant rotating metal fan called a turbine. That turbine turns the shaft of a huge generator. Inside the generator, coils of wire and magnetic fields interact - and electricity is produced.
