Hotline About Hotline 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 About Technology 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.	Web Crawler About Web Crawler 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.	Mobile System About Mobile System 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 About Lessons Learned Lessons learned provides a repository of documents published by the decommissioning and dismantlement community users. This allows them to share their experience with the community.	Best Practices About Best Practices Best practices provides a repository of decommissioning and dismantlement best practices documents that the user community can upload to the system.	Picture Video Library About Picture & Video Library 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.	Document Library About Document Library 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.
Specialist Directory About Specialist Directory 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.	Vendors About Vendors Vendor management provides a directory of decommissioning and dismantlement vendors along with their contact information.	Collaboration Tools About Collaboration Tools 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.	Training About Training 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.

contaminated stacks characterization > Solution Details

Stack Characterization

Solution entered: 6/19/2008 Solution updated: 6/26/2008

Characterization: DOE’s Decommissioning Handbook contains information about Characterization (Section 7), Demolition (Section 10) and Section 11 on Remote Technology. See link. Surveying the inside will be difficult. Options include opening instrument lines or any other openings in the stack and swabbing the inside. Additional openings can be core drilled through the stack wall and swabs taken from the inside. Recommend reading the attached articles that contain info about D&D and stacks. Controlling Contamination Spread: Recommend reading the success story on the Encapsulation Technologies website. See photos of the BROKK Demolition Machine. The BROKK was suspended 100’ off the ground and run remotely from a nearby building. At Hanford we have removed stacks using explosives. The company was Controlled Demolition Inc. See their website and click on "Chimneys”. A detailed IAEA report has been issued on Dismantling Contaminated Stacks; See link
