Webfission, νd, can be calculated by integrating over all time for a single fission. Thus: νdnii i ni i i ==∑∑PR Pc The total decays of nuclide i per fission, R i, is equal to the cumulative fission product yield of i. Thus, for a pure sample of an actinide, if the cumulative yields, c i are known the νd can be calculated.
