In 1986, core samples and samples of debris were obtained from the corium layers on the bottom of the reactor vessel and analyzed.

However, the corium did not breach the steel containment vessel 1.9 metres further down within the concrete, or the boundary of secondary containment some 7.6 metres further still.

Of the 10.2 metres of solid concrete that makes up the floor of the reactor building, the corium is thought to have melted and mixed with the first 70 centimetres only.

Tepco said it was confident the melting had ceased due to the absence of gases that would be released by the high-temperature reactions between corium and concrete.
