- A subcritical mass cannot sustain a nuclear chain reaction, it dies exponentially
- A critical mass can sustain a nuclear chain reaction, but it remains constant neither increasing nor decreasing
- A supercritical mass not only sustains a nuclear chain reaction but it increases exponentially until the mass explodes
A nuclear fission bomb must become supercritical at some time in order to explode.
What else can I help you with?
What is meant by supercritical andhow dose it relate to making a nuclear bomb?
subcritical - a mass or arrangement of fissionable or fissile material unable to sustain a neutron chain reaction. It can provide a fixed amount of neutron multiplication from a neutron source, but after removal of the neutron source the chain reaction rate drops exponentially.critical - a mass or arrangement of fissionable or fissile material capable of sustaining a constant neutron chain reaction. No increase or decrease. (Nuclear reactors operate at critical)supercritical - a mass or arrangement of fissionable or fissile material capable of not only sustaining a neutron chain reaction, but once initiated the chain reaction rate rises exponentially. (Nuclear fission bombs explode when made supercritical)A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
What is nuclear settlement?
Nuclear settlement usually refers to a negotiated agreement between countries or parties regarding the use, possession, or development of nuclear weapons or nuclear energy. These settlements often involve terms and conditions meant to prevent the proliferation of nuclear weapons and ensure the safe and responsible management of nuclear technology.
The differences between nuclear reactors and nuclear bombs include what?
Nuclear reactors produce exactly one additional fission for each fission reaction while nuclear bombs don't Nuclear bombs are runaway fission reactions and reactors aren't (APEX)
How is nuclear energy abused?
Nuclear energy is simply electricity produce via a nuclear reactor, so nuclear energy would be abused in the same way as electricity produced by any other conventional means (such as wind, solar, hydro, wood or other bio fuel burning, or coal or natural gas burning, etc.), this being the unnecesary useage and thus wasting of electricity.
What is nevtron?
"nevtron" appears to be a misspelling. If you meant "neutron," it is a subatomic particle found in the nucleus of atoms, along with protons. Neutrons have no electric charge and play a key role in nuclear reactions and stability.

What is meant by nuclear cold test?
testing without nuclear explosion
What is meant by nuclear hazards?
The nuclear hazards are caused by nuclear material. It is present in different parts of world.
How is Nuclear energy covered?
What is meant by 'covered'?
How do nuclear atoms differ from regular atoms?
All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."
How is energy lost in a nuclear reactor?
how am i meant to know you
Functions of nuclear reactors?
One of the primary functions of a nuclear reactor is to maintain a chain reaction. Also, nuclear reactors are meant to provide a steady flow of neutrons.
What is meant by nuclear physics?
It means, physics of the nucleus - meaning the atomic nucleus.
Who ranks first in nuclear weapons?
Russia currently has the most, if that is what you meant by first.
What are the goals the other major countries involved in nuclear biological weapons?
I know of no "nuclear biological" weapons, perhaps you meant nuclear, biological, chemical (NBC) weapons, which can be any one of these.
What process stars when a star is born?
Assuming you meant "What process starts" the answer is nuclear fusion.
What is meant of oxidation reduction in photosynthesis?
It is about making NADPh. making NADPH by NADP.
