http://large.stanford.edu/courses/2011/ph241/grayson1/ A nuclear reactor core is the portion of a nuclear reactor containing the nuclear fuel components where the nuclear reactions take place and the heat is generated. Typically, the fuel will be low-enriched uranium contained in thousands of individual fuel pins. The core also contains structural components, the means to both moderate the neutrons and control the reaction, and the means to transfer …
Web16 jul. 2008 · This also helps to keep the working temperature of the core within safe limits for the materials used in the construction of the reactor. Hence a coolant plays an important role in components of nuclear power plant and serves the dual purpose of removing the heat from the reactor as well as transferring it to the electricity generation circuit ...

WebThere are two basic types: the pressurized-water reactor (PWR) and the boiling-water reactor (BWR). In the PWR, water at high pressure and temperature removes heat from the core and is transported to a steam … WebLooked at functionally, the three basic safety functions in a nuclear reactor are: To control reactivity. To cool the fuel. To contain radioactive substances. The main safety features of most reactors are inherent – negative temperature coefficient and negative void coefficient.
WebThe Role of Cooling in Fossil and Nuclear Power Plants. Generally, fossil and nuclear power plants use water for heat transfer in two ways: Internal Energy Transfer. To convey steam heat created by the energy source - either the coal furnace or the reactor core - to power an electricity-generating turbine; and; Cooling and Surplus Heat Discharge.
A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity.
