Safety Analysis Report for Packaging (SARP)

RSICC is pleased to announce the release of MCNP6.1.1 Beta from Los Alamos National Laboratory. It is recommended that MCNP6.1.1Beta not to be used for production level calculations, because it does not have the same level of verification, validation and testing as MCNP 6.1, both in the evaluation of new features and existing feature interoperability, and testing on a wide variety of hardware and operating systems. However, if users wish to perform their own V&V, it is ultimately up to their careful consideration how these executables should be used. This release does have the same high level of confidence for the existing capabilities released in MCNP 6.1. This release was created for users interested in testing the new capabilities that are mostly for homeland security and non-proliferation applications. The beta version does not include new capabilities for the criticality safety community, but does run significantly faster than the production version. The MCNP package available from RSICC contains the final production version of MCNP 5 and MCNP X, and the latest production version of MCNP 6, in addition to this beta release and the associated nuclear and atomic data. Customers that have already obtained either the source or executable version of MCNP6.1 will only be sent a single DVD that contains the beta code. All other individuals will receive the full complement of codes as stated previously. Furthermore, the cost recovery fee will be waived for all requests received prior to 4:00pm on September 12, 2014 for those customers that normally would be required to pay the fee.
