NUCLEAR BLU TACK.

A team tasked with decommissioning a nuclear reactor came up with a simple solution when they needed to take samples from its core - Blu Tack.

Workers at Dounreay, near Thurso, in Caithness, had to take samples of metal from holes drilled into the base of the Prototype Fast Reactor (PFR).

So they attached Blu Tack to the end of a long, flexible rod and inserted it nearly 10m into the reactor core - saving the cost of developing a specialist tool for the job.

Samples of the metal stuck to the Blu Tack and were collected for analysis.

Calder Bain, of the PFR design team, said: "There is a continual requirement for inventive methods to dismantle a nuclear reactor." WWF Scotland's Lang Banks said: "The ingenuity of those involved in cleaning up Dounreay's radioactive legacy has to be praised."
