Natural Circulation | Definition & Conditions | nuclear-power

Natural convection, also known as free convection, is a mechanism, or type of mass and heat transport, in which the fluid motion is generated only by density differences in the fluid occurring due to temperature gradients, not by any external source (like a pump, fan, suction device, etc.).. In natural convection, fluid surrounding a heat source receives heat, becomes less dense, and

Application of Heat Pipes to Fissionable Nuclear Reactor

Heat pipes are often proposed as cooling system components for small fission reactors. Heat transport in heat pipe reactors is complex and highly system dependent. Nevertheless, in general terms it relies on heat flowing from the fuel pins through the heat pipe, to the heat exchanger, and then ultimately into the power conversion system and heat sink. Heat pipes have been used in

Heat Transfer | Definition, Mechanisms & Application | nuclear-power

The heat source in the nuclear power plant is a nuclear reactor. As is typical in all conventional thermal power stations, the heat is used to generate steam which drives a steam turbine connected to a generator that produces electricity. But in nuclear power plants, reactors produce an enormous amount of heat (energy) in a small volume.

The heat transport system brings the heat produced by the reactor to the steam generators. This system is made up of very robust pipes, filled with heavy water - a rare type of water found in nature. Pipes and other components are maintained and inspected regularly, and replaced if

Turbine Generator

The layout of nuclear power plants comprises two major parts: The nuclear island and the conventional (turbine) island.The nuclear island is the heart of the nuclear power plant. On the other hand, the conventional (turbine) island houses the key component which extracts thermal energy from pressurized steam and converts it into electrical energy, the turbine generator.

Convection

Mechanisms of Convection. In thermal conduction, energy is transferred as heat either due to the migration of free electrons or lattice vibrational waves (). There is no movement of mass in the direction of energy flow, and heat transfer by conduction depends on the driving "force" of temperature difference. Conduction and convection are similar in that both mechanisms
