X-energy, Dow apply to build an advanced reactor project in Texas
Dow and X-energy announced today that they have submitted a construction permit application to the Nuclear Regulatory Commission for a proposed advanced nuclear project in Seadrift, Texas. The project could begin construction later this decade, but only if Dow confirms “the ability to deliver the project while achieving its financial return targets.”

This workshop will cover many of the new features, improvements, and updated tools included in the latest MCNP6.3 code release that are most relevant to the radiation protection and shielding community. While more details of the workshop will be forthcoming, a few of the topics to expect at this workshop include:
MCNP6.3 Unstructured Mesh Geometry
This workshop will cover the unstructured mesh capability in the latest MCNP6.3 code release including some relevant exercises relevant to the radiation protection and shielding community. While more details of the workshop will be forthcoming, a few of the topics to expect at this workshop include:
• An overview of the unstructured mesh capability in MCNP6, highlighting the evolution of this capability within the versions of the MCNP6 code releases
• Discussion on the Abaqus format expected by the MCNP code
• Overview of HDF5-based input/output of the unstructured mesh mesh model and elemental edit file (eeout)
• New geometry and tally visualization options through XDMF-based output
• Ongoing developments in progress for MCNP6.4
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.
