Title: $$\beta $$ Decays of $$^{92}$$Rb, $$^{96\mathrm {gs}}$$Y, and $$^{142}$$Cs Measured with the Modular Total Absorption Spectrometer and the Influence of $$\gamma $$ Multiplicity on Total Absorption Spectrometry Measurements

Abstract

Total absorption spectroscopy is a technique that helps obtain reliable β-feeding patterns of complex decays important for nuclear structure and astrophysics modeling as well as decay heat analysis in nuclear reactors. The need for improved measurements of β-feeding patterns from fission decay products has come to the forefront of experiments that use nuclear reactors as a source of antineutrinos. Furthermore we present more detailed results, in particular the β-decay measurements of ^96gsY, and demonstrate the impact of the β-delayed γ multiplicity on the overall efficiency of Modular Total Absorption Spectrometer used at Oak Ridge National Laboratory to study the decays of fission products abundant during a nuclear fuel cycle.

Decays of the Three Top Contributors to the Reactor ${\bar{ν}}_{e}$ High-Energy Spectrum, ${}^{92}{Rb}$ , ${}^{96 gs}Y$ , and ${}^{142}{Cs}$ , Studied with Total Absorption Spectroscopy

Journal Article Rasco, B. C. ; Wolińska-Cichocka, M. ; Fijałkowska, A. ; ... - Physical Review Letters

Here, we report total absorption spectroscopy measurements of ⁹²Rb, ⁹⁶^gsY, and ¹⁴²Cs β decays, which are the most important contributors to the high energy ν¯_e spectral shape in nuclear reactors. These three β decays contribute 43% of the ¯νe flux near 5.5 MeV emitted by nuclear reactors. This ν¯_e energy is particularly interesting due to spectral features recently observed in several experiments including the Daya Bay, Double Chooz, and RENO Collaborations. Measurements were conducted at Oak Ridge National Laboratory by means of proton-induced fission of ²³⁸U with on-line mass separation of fission fragments and the Modular Total Absorption Spectrometer.

Complete β-decay patterns of ¹⁴²Cs,¹⁴²Ba, and ¹⁴²La determined using total absorption spectroscopy

Journal Article Wolinska-Cichocka, Marzena ; Rasco, B. Charlie ; Rykaczewski, Krzysztof P. ; ... - Physical Review. C

Background: The β decays of fission products produced in nuclear fuel are important for nuclear energy applications and fundamental science of reactor antineutrinos. In particular, nuclear reactor safety is related to the decay modes of radioactive neutron-rich nuclei, primarily via the emission of γ rays, neutrons, and electrons. Additionally nuclear reactors are the most powerful man-made source of antineutrinos emitted during the β decay of fission products. These antineutrinos are used to inspect fundamental properties of leptons as well as informing reactor operation. However, the majority of data on complex decays of fission products collected in the evaluated nuclear data repositories like Evaluated Nuclear Structure Data File (ENSDF) and Evaluated Nuclear Data Files (ENDF) are based on low-efficiency and often incomplete measurements resulting in questionable reference reactor antineutrino flux predictions, see the analysis by [Nichols, J. Nucl. Sci. Technol. 52, 17 (2015)]. Various assessments like the one done under the auspices of the [Yoshida et al., Assessment of Fission Product Decay Data for Decay Heat Calculations: A report by the Working Party on International Evaluation Co-operation of the Nuclear Energy Agency Nuclear Science Committee (Nuclear Energy Agency, Organization for Economic Co-operation and Development, Paris, France, 2007), Vol. 25], as well as by [Sonzogni, Johnson, and McCutchan, Phys. Rev. C 91, 011301(R) (2015)] and [Dwyer and Langford, Phys. Rev. Lett. 114, 012502 (2015)], list the A = 142 isobars with high cumulative fission yield among the important nuclei where data for reactor decay heat and/or antineutrino production should be verified and/or improved. Purpose: Here, our goal is to improve the quality of β -decay measurements and evaluate the impact of modified decay schemes on reactor decay heat and antineutrino energy spectra, for fission products along the A = 142 isobaric chain. This work is an in depth follow-up on [Rasco et al., Phys. Rev. Lett. 117, 092501 (2016)]. which presented briefly the impact of the corrected decay scheme of ¹⁴²Cs . Here, we extend the data to full isobaric decay chain including the daughter nuclei, ¹⁴²Ba and ¹⁴²La, and present more details on the ¹⁴²Cs results. Method: The decays of neutron-rich isobars of mass A = 142 produced by means of proton-induced fission of 238 U were measured using the Modular Total Absorption Spectrometer (MTAS) array on-line at the mass separator and Tandem accelerator at Oak Ridge National Laboratory. Results: The β -decay schemes for ¹⁴²Cs and ¹⁴² La were modified with respect to the nuclear data repositories. A small β-delayed neutron branching ratio for ¹⁴²Cs emitter was remeasured asmore »« less

Determination of β-decay feeding patterns of ⁸⁸Rb and ⁸⁸Kr using the Modular Total Absorption Spectrometer at ORNL HRIBF

Journal Article Shuai, Peng ; Rasco, B. C. ; Rykaczewski, Krzysztof P. ; ... - Physical Review. C

We report precise determination of ground-state feeding in the β decay of fission products is an important but challenging component in modeling reactor antineutrino flux and reactor decay heat. The Modular Total Absorption Spectrometer (MTAS) is a versatile NaI(Tl) detector array that determines the true β-decay pattern free from the pandemonium effect, including precise ground-state feeding intensities. In this paper, we report MTAS results of the β feeding intensities of ⁸⁸Rb and ⁸⁸Kr, fission products with large cumulative yields in nuclear reactors. By comparing MTAS results with previous measurements, ⁸⁸Rb provides a validation of MTAS's ability to determine ground-state feedingsmore »« less

Deciphering Nb 98 β decay with the Modular Total Absorption Spectrometer at ORNL

Journal Article Rasco, B. C. ; Rykaczewski, K. P. ; Fijałkowska, A. ; ... - Physical Review. C

An assessment done under the auspices of the Organization for Economic Co-operation and Developement Nuclear Energy Agency (OECD-NEA) in 2007 suggested that the β decays of many abundantly produced fission products in nuclear reactors may be incomplete. In this assessment, the fission product ⁹⁸Nb was assigned the highest priority for study by total absorption spectroscopy due to its large cumulative fission branching fraction and because the β-decay data from several experiments are discrepant. To obtain the complete β-decay feeding pattern of ⁹⁸Nb and determine the impact on the average γ energy per ⁹⁸Nb β decay and v¯e emission calculations. Themore »« less

Impact of Modular Total Absorption Spectrometer measurements of $β$ decay of fission products on the decay heat and reactor ${\bar{ν}}_{e}$ flux calculation

Journal Article Fijałkowska, Aleksandra G. ; Karny, Marek ; Rykaczewski, Krzysztof P. ; ... - Physical Review Letters

Here, we report the results of a β-decay study of fission products ⁸⁶Br, ⁸⁹Kr, ⁸⁹Rb, ⁹⁰^gsRb, ^90mRb, ⁹⁰Kr, ⁹²Rb, ¹³⁹Xe, and ¹⁴²Cs performed with the Modular Total Absorption Spectrometer (MTAS) and on-line mass-separated ion beams. These radioactivities were assessed by the Nuclear Energy Agency as having high priority for decay heat analysis during a nuclear fuel cycle. We observe a substantial increase in β feeding to high excited states in all daughter isotopes in comparison to earlier data. This increases the average γ-ray energy emitted by the decay of fission fragments during the first 10 000 s after fission ofmore »« less
