What else can I help you with?
What is η?
It is the thermal regeneration factor. It is greater than one. It is ratio of neutrons generated in the fuel to the absorbed neutrons.
What is fissile?
a thermal slow neutrons that will fission by a chain reaction of the nutrons.
What uranium nucleus is fissile?
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
What does thermal indicates in thermal neutrons?
A thermal neutron has much less energy / velocity than a fast neutron. As a result, it has a much larger neutron absorption cross section, making it easier for it to be absorbed by certain nuclei and subsequently initiate fission. The fast neutrons that result from fission are slowed down, i.e. moderated, usually by water, in order to become thermal neutrons and to sustain the fission chain reaction.
The uranium 238 atom can be triggered to split when its struck by a?
By neutrons; bu the cross specific area is very small for thermal neutrons.
Is the detection of neutrons dependent on the energy of the neutrons?
Yes. There are different kinds of detectors for neutrons. Some are better at detecting high energy neutrons, and some are better at detecting thermal neutrons. There is no detection method that is equally good for detecting neutrons at all energy levels.
What has the author Ludwik Dobrzynski written?
Ludwik Dobrzynski has written: 'Neutrons and solid state physics' -- subject(s): Scattering, Thermal neutrons
Are there free neutrons in the sun?
yes
Why are neutrons fired at the uranium nuclei?
Under bombardment with thermal neutrons a nuclear fission is produced with the isotopes 235U and 233U; a formidable energy is released after fission.
What reaction must uranium undergo in order to release energy?
Nuclear fission with thermal neutrons
Uranium 235 can be split if its hit by what?
Uranium-235 can be split if it is hit by a neutron, which can induce a fission reaction. This process releases energy and more neutrons, which can then go on to split other uranium atoms in a chain reaction.
