Dounreay Site Restoration Ltd (DSRL)

Overview

Dounreay Site Restoration Ltd (DSRL) manages the decommissioning of the former Fast Reactor Research site in Scotland. The site contains three reactors, two reprocessing plants and a number of other facilities.

Orano Limited activities

Orano  Limited is a specialist safety subcontractor to Jacobs Ltd. Under this contract, Orano Limited personnel were embedded into the DSRL organisation to produce safety cases and modifications in support of site decommissioning activities.

Value added

• Providing embedded support to produce a staged safety case in support of the export from the site of a number of unirradiated, but complete Prototype Fast Reactor sub-assemblies.
• Proposal of an alternate flask as a contingency, when a risk to the original flask availability occurred.

Value for client

The safety case was produced with minimal supervision and cleared site’s due process without difficulty. The case was designed so that the later permissions for commissioning and operations could be completed by the operators, without assistance from safety case specialists.
