In 2013, North Korea said that it was going to restart all of its nuclear facilities. Now, the country says that it is improving its nuclear weapons “in quality and quantity”.

The country says that its main nuclear complex Yongbyon is fully operational. The reactor in Yongbyon makes plutonium for nuclear bombs. If it is working, it can make enough plutonium for one bomb every year.

North Korea says that it can use the weapons against the USA at any time.

Difficult words: facility (a building with special equipment or things), improve (to make something better), fully operational (ready to be used).
