    Other Details

    Minimum Class Enrollment

    There is a minimum number of participants required for each class to be held. Registered class participants will receive an email no later than four weeks before the class start date (by September 02, 2024) notifying them if a class is cancelled because of low enrollment.

    Refunds

    If the class is cancelled because of low enrollment, participants may request a refund of any registration fees paid or may request that the fee already paid be credited towards their attendance at a future class.

    If you cannot attend the class for another reason and cancel your registration less than four weeks in advance (after September 02, 2024), we will be unable to refund any registration fee paid. However, the fee may be applied towards attendance at a future class. Alternatively, another person from your organization may attend in your place, depending on the citizenship of that individual. Contact the MCNP Registrar for further information.

    Last-minute Registrations

    Registrations received within two weeks prior to the start of a class (after September 16, 2024) may be accepted on a space-available basis and depending on the citizenship of the person registering.

    Non-US Citizens

    Registration requests for non-US citizens who are citizens of a country listed in US Regulation 10 CFR 810 are processed by the LANL Foreign Visits Office. This security approval processing is based on requirements issued from the US Department of Energy. The processing normally takes at least 60 days. You must register and provide all requested information by July 12, 2024. Although we can never guarantee that a security approval will be received, we will make every attempt to obtain an answer for your attendance request as soon as possible.

    Registration requests for non-US citizens who are citizens of or reside in a country not listed as a Generally Authorized Destination in US Regulation 10 CFR 810 cannot be processed by LANL and will be submitted directly to the Department of Energy.

    For a list of 10 CFR 810 countries, please go to the Electronic Code of Federal Regulations, 10 CFR 810.

    Pre-class Information

    Students who are fully registered and have confirmed payment for the class are ready to attend. This webpage lists the details needed to attend.

    However, prior to arrival the student must accomplish two critical steps with the computer he or she will use for the class:

    1. Install and test MCNP6.2 or MCNP6.3.
    2. Download the class materials (presentations, example input files, etc.).
      • A download link for a ZIP file containing class materials will be provided to registered and fully paid attendees the week, typically the Thursday, before the class.
      • The download is approximately 500 MB and should be fully extracted for use.

    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.

    Arriving

    Visitors to Los Alamos National Laboratory (LANL) usually fly into either Santa Fe Regional Airport (SAF) or Albuquerque International Airport (ABQ).

    Google Maps-based driving directions from each are:

    Other LANL-focused arrival information is available here.

    When arriving at Los Alamos National Laboratory, all vehicles pass through a vehicle access portal (VAP) where drivers will need to present current photo identification such as a state-issued driver's license or LANL-issued badge. Note that the VAPs on the Pajarito corridor require a LANL-issued badge.

    All visitors must obtain a badge as the first part of their visit. Identification requirements as of August 2023 are listed here. The LANL badge office (and the MCNP classroom) are located in the
