UK decay data libraries are used to undertake calculations for the nuc
lear power, fuel processing and waste management programmes. The activ
ation-product decay data library has been further developed in 1993/94
, with the incorporation of a number of minor modifications to the exi
sting data files and the addition of comprehensive, evaluated decay da
ta for 97 radionuclides. These data have been prepared in ENDF-6 forma
t to produce a library that contains full decay-scheme data for a tota
l of 328 activation products.
