building

In September 2010 construction began on a project to enclose the damaged reactor. The structure will create a space in which the most hazardous components can be dismantled and a complex ventilation system will use negative pressure to keep any radioactive dust inside

In 2017, if all goes to plan, the 31,000-tonne arch will be gently pushed along Teflon rails to cover the radioactive remains of the reactor
