What is the nuclear fuel cycle?

The nuclear fuel cycle covers the safe and sustainable management, storage, processing, or final disposal of the uranium mineral. This process includes extraction from the mine, processing, loading into the reactor, and the subsequent removal of used fuel from the nuclear reactor.

How does the process work after used nuclear fuels are removed from the reactor?

Used fuels are placed in cooling ponds for at least five years. Subsequently, various methods, including long-term storage in underground facilities, temporary storage in special containers, and underwater storage in pools, are considered as options. Most importantly, it is never released into the environment.
