fission yield

[′fish·ən ‚yēld]

(nucleonics)

The amount of energy released by fission in a nuclear explosion, as distinct from that released by fusion.

(nuclear physics)

The percent of fissions that gives a particular nuclide or group of isobars.

The total propagated uncertainty coming from both nuclear data (fission yield and cross sections) and manufacturing data is obtained by applying the process previously described in [8, 9].

So, the uncertainty is the result of fission yield and cross section uncertainty propagation.

We showed in [9] that nuclear data uncertainty propagation gives 0.6% at 1a in the core centre and that fission yields were negligible for power factors uncertainties.

In a second step, a complete uncertainty propagation of all uncertain data (nuclear data such as cross sections and fission yields and manufacturing data) through the depletion cycle has been performed to observe the combination of all these uncertainties.

The only isotope of major concern here is [sup.131]I, which is volatile, and has a high fission yield and a short half life of just eight days.
