Nuclear Weapons defines an "accident involving nuclear weapons" as "An unexpected event involving nuclear weapons or nuclear weapons components that results in any of the following:
The RadPiper robot is launched into a pipe Image: Carnegie Mellon University The RadPiper robots will first be deployed at the former Portsmouth gaseous diffusion plant, in Piketon, Ohio, which operated from to and contains over 75 miles kilometres of process pipes.
Uranium deposits inside the pipes must be located before facilities can be decontaminated, decommissioned and demolished. Up to now, this has been done by external measurements carried out by human crews. This is both time-consuming and hazardous, with workers needing to wear protective clothing and use scaffolding or lifts to reach elevated pipes.
The tetherless robot moves through the pipe on a pair of flexible tracks and characterises radiation levels in pipe segments of 1 foot about 30 centimetres in length. Segments with potentially hazardous amounts of fissile uranium can then be removed and decontaminated separately.
The robot will initially be used in pipes with diameters of 30 inches and 42 inches. The disc-collimated sensing instrument, for which CMU is seeking a patent, uses a standard sodium iodide sensor to count gamma rays.
This is positioned between two large lead discs, which block gamma rays beyond the segment currently being characterised. They could also save some USD50 million in costs at the Paducah plant in Kentucky, which is also being decommissioned. A prototype has already been tested at the plant, to which the first RadPiper robots will be delivered in May.DECEMBER 18, ISSUE.
