Liquid-fuel molten-salt reactors are also inherently safer because as the liquid heats up, it expands, slowing the nuclear reactions
. In addition, the reactor is built with a drain plug, kept solid by an electric cooler in the bottom.
In the present work, we have calculated the total nuclear reaction
cross section for the collision of various projectiles, by using Coulomb modified Glauber model such as [sup.56][Fe.sub.26], [sup.84][Kr.sub.36], [sup.132][Xe.sub.54], [sup.197][Au.sub.79], and [sup.238][U.sub.92] with different composition elements of the nuclear emulsion nuclei at incident energies [E.sub.lab] ~ 1GeV/n.
Evaluation of nuclear reaction
cross sections relevant to the production of emerging therapeutic radionuclides.Ph.D.
But a closer inspection reveals grain boundaries that can trap freed electrons, which means one would not see a current pulse to indicate a nuclear reaction
in the detector, explained McGinnis.
"If water was to come into contact with that uranium it could set off a nuclear reaction
Today, property policies exclude loss or damage due to a nuclear reaction
, radiation or radioactive contamination arising from a nuclear event.
To trigger a nuclear reaction
inside a reactor, a speeding neutron collides with the nucleus of a uranium atom.
Ma Xuquan of Qinghua University's Institute of Nuclear Research said the chances of an accident ''will be nil'' as the nuclear reaction
can be automatically slowed down if the accumulated heat reaches a set security limit, according to the report.
Hau's diary indicates that by this time scientists from the Chungshan Institute of Technology in charge of the program had already achieved a controlled nuclear reaction
, the last step before constructing a bomb.
This may have created a "critical mass" allowing a nuclear reaction
to start in a way similar to what occurs in a nuclear power plant.
Since February, there have been eight breaches of the "criticality" rules designed to stop a nuclear reaction
like the one in Japan last month.
