6.3 MATERIAL RELEASE IN CRITICALITY EXCURSIONS
The radionuclides generated by an excursion are a function of the fissionable material
undergoing the reaction.The quantity of each fission product or actinide formed is a
function of the total fission yield.Reference values for the various systems were designated
in the previous section.Estimation of fission product quantities can be done with computer
codes,such as ORIGEN2,or by simple ratios (total fissions for scenario/1E+19 fission) to
values in NRC regulatory guides prepared for fuel cycle facilities.The regulatory guides do
not include particulate fission product generation,and are thus less precise than computer
codes.However,the quantity of particulate fission products are normally small,their
potential release fractions are likewise small,and,unlike noble gases and iodine,they are
subject to facility filtration.Accordingly,not accounting for them is typically an adequate
approximation.It is noted again that site personnel should perform whatever background
work they believe is warranted to verify that unusual or unique circumstances do not exist at
their facilities.
The anticipated quantities and radionuclides generated by solution criticalities with total
fission yields of 1E+19 fissions involving three fissionable material compositions are:
