NJOY:  Data Processing System of Evaluated Nuclear Data Files in ENDF format.

Recent Updates

  • upnea035_up259 recommended updates to NJOY99.259 (10 July 2008)
    The patches have no impact on existing processed libraries. The patches upnea033 to upnea035 affect the processing of new evaluations with resonance covariances in compact format representation.

    The patches upnea025 to upnea028 apply only to dosimetry library processing (such as IRDF-2002 or activation data in dosimetry ACE format). Processing of the data in ENDF File-10 is affected. Patch upnea028 increases the reserved array size to process U-238 and Gd-nat from IRDF-2002. Patches P262 to P264 were in the meantime withdrawn.

    The processed IRDF-2002 library in dosimetry ACE format for the MCNP family of codes is available from www-nds.iaea.org/irdf2002/
