MCNP6.1 is the new production version of MCNP [1] released in June 2013. An updated beta version, MCNP6.1.1, is targeted for release in summer 2014 to enable the use of several new features for homeland security and nonproliferation applications. The beta version does not include new capabilities for the criticality safety community, but does run significantly faster than the production version. From 2003 – 2013, the production version was MCNP5, with MCNP5-1.60 the final release in 2010.
