Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

Westinghouse Electric Company recognizes the importance of supporting students pursuing a career in reactor physics. For this reason, Westinghouse will be sponsoring the first 100 student workshop registrants by covering their fees. Contact registrar@ans.org for a discount code before registering. Limited space available in each workshop. Once these seats are filled, you will be put on a waitlist. You must request a discount code before registering. No refunds will be made if you do not contact us before registering.
This workshop will cover many of the new features, improvements, and updated tools included in the new MCNP6.3 code release that are most relevant to the reactor physics community. While more details of the workshop will be forthcoming, a few of the topics to expect at this workshop include:
All the workshop materials, including slides, exercises, documentation, etc., will be made available to all participants. There will be live exercises done by the instructors. Participants interested in performing the exercises will need to bring their own laptop with the MCNP6.3 software installed (see how to obtain the MCNP6.3 code here ( https://mcnp.lanl.gov/how_to_get_the_mcnp_code.html ), along with a few other openly available tools (e.g., Python, MCNPTools, ParaView). Earlier versions of the MCNP6 code, i.e., MCNP6.2 and earlier, will not be able to perform the exercises provided. Details on the additional software and versions required will be communicated well before the workshop. Attendees are not required to participate in the exercises performed during the workshop nor are they required to have a license to the MCNP6 code. Instructors will be available to discuss participant questions regarding the workshop materials.
To join the conversation, you must be logged in and registered for the meeting.
