The design and processing of SONG library

Multi-group cross section library is the basic condition for lattice calculation, which provides the necessary nuclear data parameters. The multi-functional lattice code SONG (Si et al. in Nucl Power Eng 35:111–115, 2014. doi: 10.13832/j.jnpe.2014.S2.0112; Chen et al. in Nucl Power Eng 35:127–130, 2014. doi: 10.13832/j.jnpe.2014.S2.0127) is developed to adapt to the research demands of different types of new reactors, especially the fourth generation (GEN-IV) reactors (Cerullo and Lomonaco in Nucl Fuel Cycle Sci Eng, 2012. doi: 10.1533/9780857096388.3.333; Giorgio et al. in Energy Policy 61:1503–1520, 2013. doi: 10.1016/j.enpol.2013.06.101). The corresponding multi-group cross section library of SONG (SONGLIB) is well designed with much effort considering the next generation reactors’ new feature in material, spectrum, burnup depth, etc. Therefore, the burnup chain (Maria and Jaakko in Nucl Sci Eng 164:140–150, 2010. doi: 10.13182/NSE09-14), energy group structure (Tholakele et al. in Ann Nucl Energy 80:279–292, 2015. doi: 10.1016/j.anucene.2015.01.038), and reaction path should be specially considered. The library SONGLIB is processed with the Evaluated Nuclear Data File (ENDF), nuclide data auxiliary processing code NJOYBAT (Si et al. 2014), and library management code MANLIB (Si et al. 2014). A series of verification work of SONGLIB is then carried out, and the calculated results are satisfied.
