The JRC must recondition various radioactive wastes that were placed in a shallow land burial site during the 1960s and 70s. One such waste type at the Ispra Site are the so-called Roman pits, 7 m high columnar concrete containers in which activated metals were deposited and immobilised with cement. JRC-Ispra has fifteen such waste forms that must be recovered, characterised and reconditioned. This paper discusses the background to the Roman pits, the development of a validation procedure for demonstrating the safe recovery of a pit, and finally, the procedure’s execution.
