Under what conditions can a non-spontaneous reaction be made spontaneous?

A non-spontaneous reaction can be made spontaneous if it is inside a controlled environment, ,This is what happens in nuclear power plants that create atomic fusion and fission in chambers that are controlled to control different particles to create nuclear active rays. These rays can be classified as alpha, beta, and gamma rays and are crucial for producing several forms of energy and proving different theories in chemistry and physics.

Ithink it is quantity of plants
