Our solution

The options were then evaluated against a set of criteria. The objective being to select the options which optimised the overall approach to dismantling. The methodologies helped the project team focus the development.

The determination of a waste strategy for the project involved consideration of the requirements for long term storage of the highly radioactive waste, the requirements for processing the waste and the interfaces between the possible processing and storage facilities and the decommissioning project. The aim being to reduce overall lifetime costs, whilst ensuring the waste was treated in a safe way.

A model of the spread of radioactive materials onto and into the decommissioning equipment was developed. This allowed strategies to be developed for the decontamination of equipment, access for maintenance and maintenance periodicy. Radiation exposure dose rates were also calculated to allow the requirements for personnel shielding to be determined and to provide information for the calculation of a radiation dose budget for the work.
