∙ 14y agoNeutrons are produced in every fission of a U-235 nucleus, and the reactor is designed so that the number of neutrons in the active core is kept constant. This means that for every nucleus that is fissioned, another one is then fissioned by one of the neutrons produced. In fact for U-235, on average 2.5 neutrons are produced out of every fissioned nucleus, but some are absorbed in the reactor material including the circulating water, and some are lost at the core boundaries. Provided that one is captured by another nucleus, the chain reaction will continue and be self-sustaining.
You may be wondering how it gets started. In fact uranium produces spontaneous fissions at a low rate, so there are always a small number even in the shutdown reactor, and by pulling out the control rods to reach reactor criticality, this number rises until the required power level is reached.

Specifically, those of stars more massive than the Sun (and therefore massive enough to overcome electron degeneracy pressure and collapse beyond the white dwarf stage), but not massive enough to overcome neutron degeneracy pressure and collapse all the way into a black hole.

Why type of radiation has the highest penetrating ability?
Neutrinos.
Which particles are the least attracted to each other?
neutrinos.
Which three subatomic particles are the lightest?
Examples: photons, gluons, neutrinos.
What is a neutrally charged subatomic particle?
You're most likely asking about the neutron. However, there are others, like neutrinos (all three types), pions, kaons, eta mesons, as well as the sigma, the lambda, and the xi particles
Where in the material creation does electrical energy originate?
what you call on this planet are called neutrinos...
What is a solar neutrinos?
Solar neutrinos are electron neutrinos that are in the sun. The sun is what produces nuclear fusion.
Can neutrinos change into other types of neutrinos?
Yes; the scienific terminology for this phenomenon is "neutrino oscillation". Neutrinos exist in three different flavours - electron, muon and tao neutrinos, listed in order of increasing mass (each also has an antiparticle). Although it is not know why this is the case, it was originally discovered that neutrinos oscillate when examining the neutrinos emitted by the sun; although primarily electron neutrinos are emitted as a result of the fusion process within the sun, the quantities of the different flavours of neutrinos detected on Earth from the sun are in roughly equal proportions.
What are the uses of neutrino?
Neutrinos are similar to electrons, but are different, in that neutrinos do not carry electric charges.
What can affect growth?
what can effect your plant growth is the neutrinos. If you have a lot of neutrinos your plant can grow rapidly.
Explanation of missing solar neutrinos?
Neutrinos are incredibly hard to detect so the "absence" of neutrinos doesn't mean they are not there. It was long thought that neutrinos did not decay. We now know they do so. Thus, the lower than expected number of neutrinos detected coming from the Sun has been fully explained. It took four decades but the problem is now fully resolved.
Are neutrinos mediated by electromagnetic interaction?
No, neutrinos are mediated by weak interactions, Photons are mediated by electromagnetic interactions.
What can affect plant growth?
what can effect your plant growth is the neutrinos. If you have a lot of neutrinos your plant can grow rapidly.
What can penetrate the sun?
Neutrinos.
Astronomers are interested in solar neutrinos because neutrinos carry with them information about?
The nuclear reactions going on in the heart of the Sun.
What does a neutrinos do?
Neutrinos are elementary particles that travel close to the speed of light, lack an electric charge, are able to pass through ordinary matter almost undisturbed and are thus extremely difficult to detect. Neutrinos have a minuscule, but non-zero, mass that was too small to be measured as of 2007.
Is neutrinos faster than light?
No.
What travels on through solids?
Neutrinos.
