DOE meeting focuses on Marshall Islands’ legacy activity
The Department of Energy Office of Environment, Health, Safety and Security (EHSS) held its annual meeting this month with the government of the Marshall Islands. The two-and-a-half-day meeting, in Honolulu, Hawaii, focused on ongoing cooperative efforts and programs related to the legacy of U.S. nuclear weapons testing from the 1940s and 1950s. The United States began cleanup operations on the islands in the 1970s.

This workshop will cover the MCNP6.3 and Whisper-1.1 code capabilities relevant to performing sensitivity/uncertainty-based criticality safety analysis. 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 and Whisper-1.1 software installed (see how to obtain the MCNP6.3 code here https://mcnp.lanl.gov/how_to_get_the_mcnp_code.html). The MCNP6.2 version of the code will likely be sufficient to perform most of the exercises included. However, earlier versions of the MCNP6 code, i.e., MCNP6.1.1beta and earlier, will not be able to perform the exercises provided. Details on any additional software 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.
