The CONSORT II research reactor achieved criticality in 1965 and operated safely until 2012, when it was finally shut down. The nuclear fuel was removed from site in 2014. Decommissioning the reactor commenced the following year. The reactor has now been demolished and the site cleared of all radioactive waste.
It is anticipated that Imperial College will apply to ONR to have its site licence revoked in late 2021, thereby freeing the land for re-use.
