You question is far from clear, but nuclear weapons use a high explosive "trigger". The chemical explosives serve to crush nuclear materials into a very dense form, starting a nuclear chain reaction. There have been many different explosives used for that purpose- explosives used in modern day weapons is rather classified, and we don't discuss classified materials here.
The chemical explosives used in most nuclear weapons since the 1960s have been PBXs (Plastic Bonded Explosives). However there are literally many dozens of different PBXs, each having different properties. PBXs were selected for safety: they are insensitive to shock or fire.
I am not sure what you mean by "cycle". The only thing I know of with a name like that was cyclonite, an explosive used in some nuclear weapons in the 1950s, but it is very shock sensitive and thus unsafe.
Some unclassified information on nuclear weapon explosives is available in Chuck Hansen's work Swords of Armageddon.
Plutonium obtained in nuclear reactors with uranium fuels after recycling of the burned fuels can be used also as a nuclear fuel.
This is a series of nuclear fusion reactions that converts ordinary hydrogen (single protons) into helium in the cores of stars somewhat heavier than the sun. The carbon, nitrogen and oxygen are only catalysts; they are not formed or destroyed. See the Wikipedia article "CNO cycle" for all the gory details.
Citric Acid Cycle TCA Cycle (tricarboxcylic acid cycle).
I think its the water cycle
The carbon cycle
most cannot, as to produce weapons grade plutonium the fuel cycle must be made very very short. however soviet RBMK reactors and the US hanford N reactor were designed explicitly to produce both electric power and weapons grade plutonium.
not really.
Water is one of the major ingredient of life. Thats why water cycle is important for living beings.
Nuclear division
Interphase
The Nuclear membrane dissolves during prophase
Mitosis is a stage of nuclear division in the cell cycle represented by the letter"M"
it does not
prophase
The telophase of mitosis (Mitosis is the second stage of the cell cycle)
Plutonium obtained in nuclear reactors with uranium fuels after recycling of the burned fuels can be used also as a nuclear fuel.
In the cell cycle, the nuclear envelope reforms around each cluster of chromosomes in telophase.
