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.
Florida International University (FIU) is conducting a series of D&D Tech Talks focusing on several D&D topics relevant to the DOE EM Complex.
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.
D&D Research for DOE EM highlights the recent, current, and ongoing research being
performed by and for DOE EM as well as international D&D research to support the high
priority D&D needs to bring the remaining cleanup projects to completion in support
of site closure. This research includes activities at and through collaborations
with academic universities, national laboratories, DOE contractor facilities, and
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.

A remotely piloted aircraft, the RQ-4 Global Hawk provided surveillance in Fukushima, it was able to capture images and temperatures to identify the boundaries of the radioactive plume.

A combat-proven HALE UAS with extraordinary ISR capabilities, providing near-real-time high resolution imagery of large geographical areas all day and night in all types of weather. The current Global Hawk enterprise is made up of four complimentary systems, or Blocks. Block 10, the initial airframe after the DARPA technology demonstration, was deployed overseas shortly after the September 11, 2001 terrorist attacks and quickly proved its usefulness. Block 20, the first production version, was unveiled in August 2006. Block 30 adds critical signals intelligence (SIGINT) capability to the Global Hawk family. And Block 40, currently in the final development stages, will provide revolutionary new capabilities with the Multi-Platform Radar Technology Insertion Program (MP-RTIP) active electronically scanned array radar. During its trials with the Air Force's 31st Test and Evaluation Squadron and during its first deployment in Operation Enduring Freedom, the Global Hawk system was shown to be flexible and dynamically re-taskable.Specifications (Block 30 and Block 40)Wingspan: 130.9 ft (39.9 m)Length: 47.6 ft (14.5m)Height: 15.4 ft (4.7 m)Gross Take-off Weight: 32,250 lbs.

They couldn’t, but airmen figured out that the plane could record the temperature in its area over time and compare the results.The process was to take an image of the temperature of the reactor and come back the next day and take an image and if it was hotter, then a problem has been identified.Over the next two months, the Global Hawk flew 20 missions, spent more than 300 hours circling the site of the power plant and snapped thousands of images to share with the Japanese government and aid groups.The Japanese earthquake wasn’t the first time the Global Hawk was used for humanitarian missions. It has flown over fires in California and also provided imagery after a 2010 earthquake destroyed much of the Haitian capital, Port-au-Prince.(Source: UAV Global Hawk Link )
