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.

Reference # : Model No :
The Westinghouse Hot Resin Supercompaction (HRSC) process is applied for volume reduction of organic bead and/or powder resin. The HRSC process has been implemented in Germany and Belgium. Another facility is under construction in China as part of a larger radwaste treatment facility.
Drying in a conical dryer is the key component of the Westinghouse HRSC process. This is a thermal process whereby water is evaporated from the ion exchange resins until 4 weight percent humidity is reached. An additional option, the Westinghouse HRSC NextGen, grinds the resins before drying to reduce the drying time and to improve compactability. Grinding of bead resin results in a better volume reduction factor than pure bead resin processing. The HRSC condensate system enables the filtering and the condensation of the steam from the conical dryer. The conical dryer is cleaned automatically.
• Drying is a proven process used throughout the nuclear industry.
• Drying is relatively inexpensive and is comparable to incineration or cementation.
• Conical dryers are simple, reliable and easy to operate.
• No secondary waste is generated.
• Reduces spring-back effects.
• Results in a high-volume reduction of approximately 1.8 to 4 (depending on the resin).
• Produces a stable mono-block matrix of compacted resin.
• Both bead and powdered resins can be processed.
• Provides good volume reduction without creating gaseous effluents.
• Does not increase the specific activity (Bq/kg) of the waste.
