Book excerpt: This book originally appeared as a text prepared for the Defense Nuclear Agency to summarize research on dynamic pulse buckling, by the authors and their colleagues at SRI International, during the period from 1960 to 1980. Geometric buckling is a measure of neutron leakage and material buckling is a measure of the difference between neutron production and neutron absorption. When nuclear fission occurs inside of a nuclear reactor, neutrons are produced. These neutrons then, to state it simply, either react with the … Meer weergeven Both buckling terms are derived from the particular diffusion equation which is valid for neutrons: $${\displaystyle -D\nabla ^{2}\Phi +\Sigma _{a}\Phi ={\frac {1}{k}}\nu \Sigma _{f}\Phi }$$ Meer weergeven By equating the geometric and material buckling, one can determine the critical dimensions of a one region nuclear reactor.

WebGlobal warming is disrupting an Antarctic current system that life on Earth relies on. The term "abyssal ocean" conjures up ominous images, and rightly so — the literal deep sea abyss is extremely dark, at or near freezing temperatures, and full of peril.
