Obtaining the Codes

How to Obtain NRC-Developed Computer Codes

In general, the NRC allows distribution of its reactor safety codes and tools to domestic organizations (utilities, vendors, academic institutions, commercial enterprises) and international organizations located in countries that participate in the Code Applications and Maintenance Program (CAMP) or Cooperative Severe Accident Research Program (CSARP).

Specific procedures for obtaining NRC codes are as follows:

TRACE/RELAP5

If you are a domestic commercial organization:

  • Fill out, sign and return this non-disclosure agreement. When complete, you may fax or email it to 301-251-7423 or safetycodes@nrc.gov
  • There are 2 levels of support provided:
    • $5,000/year. The user becomes a member of the domestic user group and is granted technical support and periodic code updates.
    • $1,000 one time fee for shipping and handling. The user is entitled to installation assistance only.
    • Code distribution and all payment transactions will be handled by the NRC contractor responsible for code distribution (in this case, Information System Laboratories, Inc).

If you are a domestic academic institution or NRC contractor:

  • Fill out, sign and return this non-disclosure agreement. When complete, you may fax or email it to 301-251-7423 or safetycodes@nrc.gov
  • The code is provided for no fee, although no technical assistance is provided.

If you are an international governmental organization located in a CAMP member country:

  • Access to the code is provided through your country's CAMP representative.

If you are an international non-governmental organization located in a CAMP member country:

  • Access to the code is provided through your country's CAMP representative.
  • In addition, you are required to fill out, sign and return this non-disclosure agreement.

If you are an international organization located in a non-member country:

  • You may request the code through the NRC's Office of International Programs.

PARCS

PARCS exists both as a stand-alone program and as a coupled version to both RELAP5 and TRACE. In general, distribution of the stand-alone version and the RELAP5-coupled version is handled directly by University of Michigan. The TRACE-coupled version is bundled directly into the TRACE distribution package so access to PARCS is automatic when requests for TRACE are made.

SNAP

SNAP is developed and maintained by the NRC's contractor, Applied Programming Technology, Inc. (APT). You can download the code directly from http://www.nrcsnap.comexit icon, but access to the site is by registration only. You must fill out, sign and return this non-disclosure agreement. When complete, you may fax or email it to 301-251-7423 or safetycodes@nrc.gov. At this point, there is no charge to domestic users for obtaining the code, although this will most likely change (to a cost structure much like that of TRACE and RELAP5) in the future. Users are encouranged to provide feedback and submit bug reports. For CAMP member country organizations, SNAP is supported and maintained like TRACE and RELAP5.

MELCOR

If you are a domestic commercial organization:

  • Fill out, sign and return this non-disclosure agreement. When complete, you may fax or email it to 301-251-7423 or safetycodes@nrc.gov.
  • $1,000 one time fee for shipping and handling. The user is entitled to installation assistance only.
  • Code distribution and all payment transactions are handled by the NRC contractor responsible for code distribution (in this case, Sandia National Laboratory). Code requests can also be made directly from the MELCOR website. exit icon

If you are a domestic academic institution or NRC contractor:

  • Fill out, sign and return this non-disclosure agreement. When complete, you may fax or email it to 301-251-7423 or safetycodes@nrc.gov.
  • The code is provided for no fee, although no technical assistance is provided.

If you are an international governmental organization located in a CSARP member country:

  • Access to the code is provided through your country's CSARP representative.

If you are an international non-governmental organization located in a CSARP member country:

  • Access to the code is provided through your country's CSARP representative.
  • In addition, you are required to fill out, sign and return this non-disclosure agreement.

If you are an international organization located in a non-member country:

  • You may request the code through the NRC's Office of International Programs.

FRAPCON/FRAPTRAN

Distribution of FRAPTRAN and FRAPCON is handled by NRC's contractor, Pacific Northwest National Laboratory. Requests for obtaining the codes can be made from the FRAPCON website. exit icon You will need to fill out, sign, and return a non-disclosure agreement available from that website.

SAPHIRE

The current version of SAPHIRE is generally distributed through the SAPHIRE Users Group:

  • Fill out, sign and return this non-disclosure agreement. When complete, you may mail to the address listed on the form or email it to safetycodes@nrc.gov.
  • The Idaho National Laboratory, the NRC contractor responsible for SAPHIRE code developement, will provide technical assistance to SAPHIRE Users Group members. Additional infomation can be found on the SAPHIRE Users Group website.exit icon
