RMCCS and RMCCSA Libraries

    Released: 1985-11-01

    RMCCS and RMCCSA are continuous-energy data libraries for use with MCNP. The data in these libraries are primarily based on END/B-V data evaluations with additions from LANL evaluations. Benchmark results using these data libraries for criticality calculations and others can be found in the documents below.
