Classification According to the Quantity of Water Available Plants are classified as follows according to the quantity of water available : Run off river plants without pondage Run off river plants with pondage. Reservoir plants. 1. Run off river plants without pondage In this type of hydro-electric plant, water from the river is not stored … Read more
Control Through Flow of Coolant Reactor coolant is used for continuously removing heat developed in the reactor core for generating steam in the exchanger. The coolant used must be fluid at operating temperature of the reactor, having high thermal conductivity in order to achieve maximum heat transfer. Further the coolant must be stable from stand … Read more
Francis Turbine of Hydro Power Plant It is a reaction type turbine. In such turbines, the total available head of water is partly used in the form of pressure energy and partly in the form of kinetic energy. They are mostly used for medium heads of water. The main parts of the Francis turbine are … Read more

Water Hammer Effect and Cavitation in Hydro Electric Power Station Q. Explain the water hammer effect and cavitation in hydro-electric power station and State the arrangement to reduce these. Water hammer effect : Any change of the water flow velocity in a pipeline causes pressure fluctuation. This is called water hammer or surge. As the … Read more
Nuclear Waste Management Every part of nuclear fuel cycle produces some radioactive waste. The radioactive waste has to be handled and disposed very carefully. The costs of handling and disposing of wastes from nuclear power plant is about 5% of the costs of electricity generated. The general considerations for classifying radioactive waste are : How … Read more
Control of Nuclear Reactor Control of Nuclear Reactor by Using Control Rods If no control is provided the nuclear fission produces a chain reaction, if such a reaction occurs at uncontrolled rate it will become a divergent chain reaction resulting into automatic bomb. In order to control the chain reaction control rods are used, which … Read more
Methods of Improving Thermal Efficiency of a Gas Turbine Power Plant The additional components such as : (1) Regenerator (2) Intercooler (3) Reheater can be used In the system for improving efficiency. Regenerator utilizes the heat of exhaust gases to heat the compressed air before it is sent to the combustion chamber. This results in … Read more
