The authorities in Ukraine have approved a giant steel cover for the radioactive site of the world's worst nuclear disaster - Chernobyl.
Ukraine has hired a French firm to build the structure to replace the crumbling concrete casing put over the reactor after the 1986 accident.
The casing project is expected to cost $1.4bn (£700m).
It will take five years to complete and the authorities say they will then be able to start dismantling the reactor.
