Reducing the Amount of Reagent to Clean Pipes and Vessels

icon for challenge

When cleaning nuclear vessels and pipework, the challenge owner seeks to reduce plant radioactivity levels by orders of magnitude, which reduces the risk and hazard for decommissioning and, in turn, lowers the lifetime costs of the redundant plants and makes the plant more economical to dismantle. This challenge is to identify a method of delivering low volumes of reagent to treat pipework walls and vessels walls rather than filling the entire pipework and vessels.

Detecting Residual Liquor and Sludges in Pipework and Vessels

icon for challenge

During the decommissioning process it is important that vessels and pipework do not contain unknown volumes of liquor and / or solid materials. As such, the challenge owner is interested in assessing technologies that allow non-invasive detection of residual liquor and sludge in vessels and pipework.

Removing Residues from Inside Pipes and Vessels

icon for challenge

The challenge is to identify a solution which can target, break down and mobilise solids (some maybe radioactive) which are not removed by existing cleansing practices and are adhered and ingrained to the internal surface of pipework or vessels. The solution needs to operate from the outside of the pipework or vessels.

Field Assessment of Granular Materials

icon for challenge

There is a requirement to analyse samples of soil removed from the challenge owner’s site to determine the nature of all extracted material prior to disposal. The challenge is to identify a solution which can provide a field assessment measurement, ideally within four hours, for asbestos and if possible for heavy metals, volatile organic compounds (VOCs), oil and explosives.
