MCNP5/MCNPX Distribution

In February, the U. S. Department of Energy (DOE) asserted jurisdiction over distribution of MCNP and its derivatives, and distribution was suspended while new guidelines were developed. RSICC recently received new guidelines and has begun distributing MCNP code packages again. Some details must be worked out before the Nuclear Energy Agency Data Bank (NEADB) can begin distributing the software.

Software containing source code is restricted and limited. Non-US citizens are strongly urged to request the “executable only” version of the software which does not contain source code. We expect turnaround time for foreign national source code requests to average 30-45 working days. Additional justification for access to the source code will be required by DOE.

Current packages affected include: MCNP5/MCNPX, MCNP5/MCNPX-EXE, MCNP-DSP, MCNP-POLIMI, and MRIPP. (For information about the compilers used to create executables in the MCNP5/MCNPX packages, click here http://rsicc.ornl.gov/rsiccnew/MCNP5-MCNPXcompilers.htm.
