A Decontamination Decision-Making Tool
Objective:
The objective of the Decontamination Decision-Making Tool (DDMT) is to assist decommissioning Project Managers to reach informed decisions with regard to the viability of applying particular decontamination techniques to the decommissioning of plant or facility area.
Added value to client:
Added Value to Client: DDMT will be used by Project Managers to determine any viable decontamination techniques that may be applied to the decommissioning task in hand.
Once the decontamination techniques datasheets are fully populated, the tool will provide users with a useful source of information on well-known and emerging technologies, from a basic description to points of contact for technology suppliers and is designed to include hyperlinks to related information sources.
Activity:
RM Consultants Ltd (RMC) was contracted to develop a data-management tool for use in conjunction with the client’s Decontamination Code of Practice.
The process of DDMT development by RMC was as follows:
- Definition of Decontamination Techniques;
- Definition of Selection Criteria;
- Development of MS Access 97 Database framework;
- Preparation and Population of the Decision Matrices for the Purpose of Filtering;
- Import Decision Matrices into MS Access, Review and Amend where necessary.
- Examining results to highlight any issues arising due to use of the 500-litre Nirex drum as a waste package from the criticality safety point of view.
The developed DDMT features a framework for a database, which will provide information on a number of identified nuclear decontamination techniques presented in the form of individual datasheets. It also features a filtering mechanism to identify viable techniques from a set of criteria, which can be chosen from a pre-determined list by the user. The filtering mechanism is based on a set of ‘decision matrices’ of decontamination technique vs. selection criteria, populated using Y/N fields.
