[Eric McClean]

i am new to nuclear science so acn anyone tell me , How does nuclear reaction start ? what the chemistry behind it .
any inputs will be welcome

Nuclear reactions do not involve 'chemistry' in the sense the chemical reactions involve atomic electrons and the bonds that form between atoms.

Fission usually involves the use of neutrons which themselves are produced from nuclear reactions.

Fusion involves nuclear collisions at high temperature usually several keV (1 keV ~ 11605000 K).
