Abstract :
Simulations of secondary neutron and gamma-ray production from the 11B(d,n)12C and 27Al(d,n)28Si reactions were conducted using an MCNPX extension called MCUNED. MCUNED enables simulation of deuteron-based nuclear reactions. Deuteron libraries from the TENDL-2010 and TENDL-2011 packages were used. The simulated neutron and gamma-ray spectra were compared to experimental results provided by Taddeucci et al. and Massey et al. The method was found to be capable of simulating neutron production from 11B(d,n)12C and 27Al(d,n)28Si, and gamma-ray production from 27Al(d,n)28Si, but not gamma-ray production from 11B(d,n)12C. The TENDL libraries appear to be more reliable for higher mass targets because of the characteristics of the Talys code.
