Advantages and Disadvantages of Nuclear Power Plant Advantages of Nuclear Power Plant A nuclear power plant reduces the demand for coal, oil, gas. Thus saving the reserves of natural resources. The area occupied by nuclear power plant is negligible as compared to that required for conventional power stations of same capacity. Small amount of fuel … Read more

Types of Nuclear Reactors 1. Pressurised Water Reactor (PWR) : It is similar to the reactor we have studied (Refer Figure. A). The arrangement of PWR is shown in figure A. The fuel used in PWR is enriched Uranium. Water under pressure is used as both moderator and coolant. The water does not boll when … Read more

Atomic Physics For better understanding of nuclear fission process, some basics related to atomic theory and be studied. Structure of an Atom A matter is said to be composed of small particles called as atoms. The nucleus is at the centre of atom and it consists of protons and neutrons. Protons are positively charged and … Read more

Pelton Wheel Turbine of Hydro Power Plant Pelton wheel has a rotor equipped with buckets along the whole periphery. The buckets used are elliptical in shape. Refer Figure A In these type of turbines the total available head of water is first converted into kinetic energy and the water having this type of large kinetic energy … Read more

Advantages and Disadvantages of Diesel Power Station  Advantages  of diesel power station : It can be installed at the load centre. It can be started in short time and can take up load immediately. Its layout design and construction are simple. Space required for installation is less, hence cost of land is less. Number of … Read more

Selection of Site for Nuclear Power Station Following factors should be taken into consideration while deciding the site for nuclear power plant: Proximity to the load centre : The plant should be close to the load centre so that transmission losses are minimized . But at the same time it should be away from populated … Read more

Layout of Hydro Power Plant Q. What are the parts of a hydroelectric power plant? Q. How does hydroelectric power plant operate draw diagram Q. How hydroelectric power plant works? Hydro electric plants require continuous flow of water with large amount of hydraulic energy. Such a source can be a natural lake or reservoir at the … Read more

Basic Concept of Hydro-Power Generation Generating stations are the energy conversion power stations. In hydro electric power station a large quantity of water is stored in dams. Thus, there is a potential energy. The stored water from the high head is carried down by penstocks (pipes) to lower heads up to water turbine. This system … Read more
