Evaluation and compilation of fission product yields 1993

Abstract

This document is the latest in a series of compilations of fission yield data. Fission yield measurements reported in the open literature and calculated charge distributions have been used to produce a recommended set of yields for the fission products. The original data with reference sources, and the recommended yields are presented in tabular form. These include many nuclides which fission by neutrons at several energies. These energies include thermal energies (T), fission spectrum energies (F), 14 meV High Energy (H or HE), and spontaneous fission (S), in six sets of ten each. Set A includes U235T,

Search for axions from the Kuo-Sheng nuclear power reactor with a high-purity germanium detector

“…The other sources of 91 Y * , 97 Nb * , 135 Xe * , and 137 Ba * are all fission daughters. Their corresponding Φ γ were derived from standard tables on fission yields [14] and cross-checked by previous calculations [10]. For comparisons, theν e [15] and ν e -yields [13] at reactors are about 7.2 and ∼ 10 −3 fission −1 , respectively.…”

Monitoring rainwater and seaweed reveals the presence of 131I in southwest and central British Columbia, Canada following the Fukushima nuclear accident in Japan

“…Some fission fragments were released as aerosols or gases and dispersed over a large geographic region through the atmosphere. The volatile fission fragment 131 I represents ∼2.89% of the fission yield of enriched uranium [1] and is of particular concern to human health. The thyroid gland concentrates iodine in order to produce two iodine-rich metabolic hormones; radioactive iodine in the environment can accumulate in the thyroid and cause an elevated risk of thyroid cancer.…”

Fission yields data generation and benchmarks of decay heat estimation of a nuclear fuel

“…The cumulative fission yields data of a nuclide can be calculated as the sum of precursors' fission yields of the nuclide [5]. The precursors' decay chains of a nuclide should be known to obtain a cumulative fission yield of a nuclide.…”
