2025 User Symposium
Table of Contents
Overview
The 2025 MCNP® User Symposium, hosted by Los Alamos National Laboratory, will be held on July 7–10, 2025 and is a hybrid event. The in-person option takes place at the J. R. Oppenheimer (JRO) Study Center, while the virtual option uses the Cvent platform.
The Symposium is designed to provide a venue for communication among the MCNP development team, MCNP users, and the Nuclear Data team. The agenda of past symposia can be found on the symposia webpage.
There are presentations given by the MCNP developers that focus on recent and planned capabilities of the MCNP code. The user community is invited to give presentations that highlight unique and challenging applications of the MCNP code.
The format is flexible so as to accommodate presentations of varying length. There are opportunities for the user community to ask questions of the developers, to request ideas from all on how to solve a particular problem, and to suggest new code or data features. Attendees do not need an MCNP license, but registration is required.

Visiting Los Alamos
The elevation of Los Alamos is approximately 7,500 ft (2,300 m). The air is thin and dry, so it is easy to become short of breath when ascending hills, stairs, etc. if not acclimated to this elevation. Remaining well hydrated is recommended.
There is abundant wildlife in Los Alamos and throughout New Mexico. Please be particularly cautious while driving at night. Further, please be alert to the presence of bears, rattlesnakes, bobcats, mountain lions, and other potentially dangerous wildlife.
