01․ The 1st nuclear plant in world was commissioned in
The first nuclear plant in world was commissioned in USSR in the year of 1954.
02․ India 1st nuclear plant was set up at
At Tarapur, India first nuclear plant was established.
03․ Nuclear fission means
The breaking up of nucleus of heavy atoms into nearly equal parts with release of huge amount of energy is known as nuclear fission. The release of huge amount of energy during fission is due to mass defect. This defect is converted into heat energy according to Einstein equation E = mc2.
|Turbines||specific speed (in s.i. units)|
|a. pelton wheel turbine||g. 50 to 250|
|b. Kaplan turbine||h. up to 50|
|c. Francis turbine||i. 255 to 866|
Specific speed of turbine is speed of a geometrically symmetrical turbine working under unit head and delivering unit break power (1 kW).
05․ Solar thermal power generation can be achieved by
06․ The function of moderator in a nuclear reactor is to
07․ Reflector of a nuclear reactor are made up of
08․ The conversion ratio of a breeder reactor is
09․ The commercial sources of energy are
The main source of energy is fuels. The fossils fuels are coal, oil and coal gas. This sources are commercial water at a high pressure or flowing with a high velocity can be used to run turbines or waterwheels coupled to generators and therefore for generation of electronic power. This method of power generation is costlier in initial cost. So this source is also commercial. The atomic energy or nuclear energy is commercial due to initial for installation and availability of uranium.
10․ Non-commercial sources of energy are
Non commercial sources of energy consist of firewood agricultural wastes, vegetable wastes, dried dung etc. These sources are supposed to be free, as they do not command any price. Actually, the non-commercial sources have started commanding prices in urban areas and to some extent in rural areas as well.
