Title: New JEF/EFF based MATXS-formatted nuclear data libraries

Journal Article · · Nucl. Sci. Eng.; (United States)
OSTI ID:5863240

Using the NJOY nuclear data processing system, three multigroup MATXS-formatted nuclear data libraries were generated based on the European data files JEF-1 and EFF-1. After processing with TRAMIX, TRANSX, or TRANSX-CTR, these libraries can be read into most transport and diffusion codes. For the neutron analysis of gas-cooled or water-moderated thermal reactor systems (including high converter pressurized water reactors), a 70-group WIMS-BOXER structured library was generated. A general-purpose fine-group library in 308 groups is provided for thermal as well as for fast reactor systems. A coupled 175 neturon/42 photon-group library in VITAMIN-J structure was created for the analysis of shielding problems and fusion blanket design. The three MATSX files can be requested from the Nuclear Energy Agency Data Bank.
