A remotely operated vehicle (ROV) the size of a transit van is to be built to help clean radioactive particles from the seabed near a nuclear site. Last year, contractors used an ROV to make an undersea search near Dounreay in Caithness. It found 115 particles.
Dounreay Site Restoration Limited (DSRL) has agreed a three-year contract with a specialist offshore company to continue the programme.
Up to 700 radioactive fragments could be found by the machine, DSRL said.
A number of robotic machines have been built to aid in the demolition of Dounreay, a former experimental power site.
Devices have included a remotely-controlled pipe crawler, built at a cost of £100,000.
