WP4777 - Dungeness A Active Drains

Description

Dungeness A Decommissioning Site (DNA) has a network of drains to allow effluent to flow from source to the Active Effluent Water Treatment Plant (AEWTP). In order to facilitate the demolition of various buildings to allow the retrieval of the site's eight boilers it is necessary to remove some of these drains and infill with grout. Two sections are to have the primary pipe removed and the secondary containment infilled with grout. Characterisation is necessary to underpin decisions for optimised disposal of the primary pipework and continued management of the secondary containment.
