a) Are the equations of nuclear reactions ‘balanced’ in the sense a chemical equation (e.g., 2H2 + O2→ 2 H2O) is? If not, in what sense are they balanced on both sides? b) If both the number of protons and the number of neutrons are conserved in each nuclear reaction, in wh...
The neutron flux spectrum and corresponding neutron cross sections are obtained by solving a simplified Boltzmann equation for each neutron group for the cell network. Note, that deterministic codes are considerably superior (several dozen times) to stochastic codes considering the calculation time. In ...
If E is energy, m is mass (the scientific word for the ordinary stuff around us), and c is the speed of light, Einstein's equation says that you can turn a tiny amount of mass into a huge amount of energy. How come? Looking at the math, c is a really huge number (300,000,...

摘要:The paper describes a finite element flow calculation using a two-equation turbulence model and variable properties, which analyses the effect of injecting a negatively buoyant flow stream into the primary circuit of a gas cooled reactor. This flow is intended to purge moisture-l...
Radioactive decay is often written in the form of an equation. The left hand side of the equation is the unstable isotope. We will call this the parent system. The right hand side shows all of the decay particles. We will call this the daughter system.Footnote 5 The equation looks ...

We are only interested in the situation where the neutron production and absorption rates are balanced; i.e., dn/dt=0. We rewrite the equation then in terms of the useful neutrons as U=S+mRf-(1+a)Rf-C-L (2) We will first illustrate the use of the equation in some well-known rea...

This discount factor (see Equation 2) is based on the assumed exogenous social discount rate that describes how society values future investments. The social discount rate should not be confused with the capital discount rate. The capital discount rate or Weighted Average Cost of Capital (WACC) ...
