STEK: A potential fast spectrum benchmark for fission product cross sections
Frontiers in Energy Research, 2023 The reactivity worth of many fission product samples was measured in fast spectrum conditions in the STEK facility during the early 1970s. These results were then used to improve and validate nuclear data evaluations for fission products, but in the last

Constraining the impact of chlorine as a neutron absorber in next-gen fast reactor designs [PDF]
Scientific ReportsThe role of chlorine as a neutron poison and as a seed for producing radioactive waste in nuclear systems has driven a renewed interest to improve its nuclear data uncertainties.

Spectral averaged cross sections as a probe to a high energy tail of 235U PFNS [PDF]
EPJ Web of Conferences, 2023 The systematic evaluations of spectrum averaged cross sections of dosimetric reactions over a broad range of energies were performed in 252Cf (spontaneous fission) and 235U(nth,f) neutron fields.

Monte-Carlo calculation of fission process for neutron-induced typical actinide nuclei fission [PDF]
EPJ Web of Conferences, 2020 A global potential-driving model with well-determined parameters is proposed by uniting the empirical asymmetric fission potential and the empirical symmetric fission potential, which can precisely calculate the pre-neutron-emission mass distributions ...

The study of prompt fission γ rays at the Oslo Cyclotron Laboratory [PDF]
EPJ Web of Conferences, 2021 The study of prompt fission γ rays (PFGs) is crucial for understanding the energy and angular momentum distribution in fission, and over the last decade there has been an revived interest in this aspect of fission.

Calibration of CFUL01 fission chambers in the standard neutron fields of the BR1 reactor at SCK CEN [PDF]
EPJ Web of Conferences, 2021 Recent subcritical VENUS-F experiments showed that fission chambers with a threshold deposit like U-238 can essentially improve the on-line sub-criticality measurments with the beam interruption method, which is currently supposed to be the main method ...

, 1943 Measurements of the spectrum of the fission neutrons of 25 are described, in which the energy of the neutrons is determined from the ionization produced by individual hydrogen recoils. The slow neutrons producing fission are obtained by slowing down the fast neutrons from the Be-D reaction of the Stanford cyclotron.

Late Prompt Fission Gamma Rays from 235U(n,f) and 252Cf(sf) [PDF]
EPJ Web of Conferences, 2020 Two measurements of fission γ rays were performed with the DANCE and NEUANCE arrays using the reactions 235 U(n, f) and 252 Cf(sf). Utilizing the fast time response of the detectors and a method for estimating the accidental background, we obtained the ...
