Search the D&D KM-IT
The hotline allows the decommissioning and dismantlement community to post problems
in a specific decommissioning and dismantlement (D&D) area and get solutions
from the subject matter specialists. Users can also search for previously published
problems and their solutions.
Technology provides information on decommissioning and dismantlement related technologies including robotics
and any associated demonstrations. It provides technology descriptions, benefits,
limitations, and associated links and documents. It also provides vendor information,
technology and demonstration fact sheet reports, and search capabilities.
The custom decommissioning and dismantlement web crawler searches and retrieve information
from decommissioning and dismantlement related websites. The crawler provides the
user with a listing of best-matching web pages, usually with a short summary containing
the document's title or parts of the text.
The mobile system component provides access to important D&D KM-IT features through wireless devices. The D&D community users can access the following modules from their mobile devices: vendor directory, specialist directory, hotline, technology information, picture library, lessons learned and best practices, and the fixative module.
Lessons learned provides a repository of documents published by the decommissioning
and dismantlement community users. This allows them to share their experience with
Best practices provides a repository of decommissioning and dismantlement best practices
documents that the user community can upload to the system.
The video/picture library allows community users to upload decommissioning and dismantlement
technology and demonstration videos and pictures to the decommissioning and dismantlement
KM-IT system. The videos and pictures could then be viewed by the decommissioning
and dismantlement community.
Weekly reports published by the ALARA center include the status of the decommissioning
and dismantlement activities that have taken place at various centers. It includes
the list of ALARA center activities for consecutive weeks. This feature makes the
reports available to the entire decommissioning and dismantlement user community.
The specialist directory provides a directory of decommissioning and dismantlement
experts in different areas along with their contact information. The user can search
the specialist directory by name or by area of interest.
Vendor management provides a directory of decommissioning and dismantlement vendors
along with their contact information.
Collaboration tools provides information-sharing mechanisms such as decommissioning
and dismantlement news, events calendars, links, message boards, and frequently
asked questions (FAQs). This allows the decommissioning and dismantlement community
to interact with fellow users.
The training component provides training videos related to decommissioning and dismantlement
work, ALARA Centers’ training material and custom training for the decommissioning
and dismantlement community.

Acceleration of decontamination can be achieved through the use of aggressive acids and complexants; however, the residual corrosive reagent and complexants can have unacceptable consequences for the downstream plant (corrosion risk and impact on abatement plant performance). For this reason, the use of such reagents is limited and may limit the scope for local decontamination options. National Nuclear Lab(NNL) along with C-Tech Innovation have developed a system that allows electrochemical treatment of spent decontaminant solutions to make them compatible with the downstream infrastructure. The system couples the option of low reagent delivery systems which keep the inventory of reagent down (e.g. 1 liter of reagent providing 4000 m2 of droplet surface area) with an electrochemical process that removes chloride and oxidizes the complexant. The system also offers the option of a post-treatment step (inline precipitation) to remove activity and other components for circumstances where tie-in to existing abatement facilities is not practicable. Trials have shown the process to be effective in reducing chloride and complexants to levels deemed acceptable to the downstream plant, with post-precipitation being shown to be effective in removing other species of interest. The project was funded through NNL Signature research funds and a Technology Strategy Board grant and was supported by input from the SL Decontamination and Effluent Technology Centres of Expertise. The process is estimated to be at a Technology Readiness Level (TRL) equivalent of 2-3. Follow on work to develop active demonstration is being explored.
