Storing Radioactive Waste
A method of storing highly radioactive waste by converting it into an insoluble glass-like solid has been announced by the UK Atomic Energy Authority (UKAEA).
So, 53 years ago, starts a story in the April 12th 1961 edition of Electronics Weekly.
The story continues:
Development work is being done by scientists and engineers of the Chemical Engineering Division at the Harwell Research Establishment.
A pilot plant to handle 1,000 curies of active waste per batch has now reached an advanced stage of design.
The glass is produced by making a slurry of silica and borax in an acidicsolution of the concentrated liquid wastes. When raised to red heat, the lurry sinters and melts and, on cooling, it solidifies into glass of chosen composition.
Experimental work has shown that the properties of the glass remain essentially unchanged when samples are subject to a radiation dose of 10¹¹ rads.
