Nuclear Power for Everybody - What is Nuclear Power
What is Nuclear Power? This site focuses on nuclear power plants and nuclear energy. The primary purpose is to provide a knowledge base not only for experienced.
X-Ray Spectrum – Characteristic and Continuous - Nuclear Power …
Internal conversion is an electromagnetic process by which an excited nuclear state decays by the direct emission of one of its atomic electrons.
Neutron Cross-section | Definition & Examples | nuclear-power.com
2014年11月21日 · In conjunction with the neutron flux, it enables the calculation of the reaction rate, for example to derive the thermal power of a nuclear power plant. The standard unit for measuring the microscopic cross-section (σ-sigma) is the barn , which is equal to 10 -28 m 2 .
Prompt Critical Reactor | nuclear-power.com
The period of ~10-5 s is very short and causes a very fast response of the reactor power in case of prompt criticality. The state of a reactor, when the chain reaction is self-sustained only by prompt neutrons, is known as the prompt critical state .
Throttling Process – Isenthalpic Process - Nuclear Power for …
A throttling process is a thermodynamic process in which the enthalpy of the gas or medium remains constant (h = const).The throttling process is one of the isenthalpic processes.During the throttling process, no work is done by or on the system (dW = 0), and usually, there is no heat transfer (adiabatic) from or into the system (dQ = 0).
Vapor Quality – Dryness Fraction - Nuclear Power for Everybody
Typically most nuclear power plants operate multi-stage condensing steam turbines. In these turbines, the high-pressure stage receives steam (this steam is nearly saturated steam – x = 0.995 – point C at the figure) from a steam generator and exhausts it to a moisture separator-reheater (point D).
Neutron Capture Cross-section | nuclear-power.com
Broadened resonance (heating of a fuel) results in a higher probability of absorption, thus cause negative reactivity insertion (reduction of reactor power). The Doppler broadening of resonances is a very important phenomenon, which improves reactor stability .
Direct Effects and Indirect Effects of Radiation | nuclear-power.com
All biological damage effects begin with the consequence of radiation interactions with the atoms forming the cells. All living things are composed of one or more cells, and every part of your body consists of cells or was built by them. Although we tend to think of biological effects in terms of the effect of radiation on living cells, in actuality, ionizing radiation, by definition ...
Beta Particles | Definition & Interactions | nuclear-power.com
Beta particles (high-energy electrons) are released as the fission fragments decay in nuclear reactors or a spent nuclear fuel pool. The glow is visible also after the chain reaction stops (in the reactor).
Isobaric Process – Heat and Energy - Nuclear Power for Everybody
It is obvious, it will be very useful in analysis of both thermodynamic cycles used in power engineering, i.e., in Brayton cycle and Rankine cycle. Isobaric process – main characteristics The volume is directly proportional to the Kelvin temperature for a …
