Advance in and prospect of moderator materials for space nuclear reactors

open access: yesInternational Journal of Energy Research, 2021
Since 1960s, many countries led by the United States and Russia have done a lot of research on space nuclear reactor power. Moderator is an important functional component in a nuclear reactor operating with a thermal neutron spectrum.

The multiscale thermal‐hydraulic simulation for nuclear reactors: A classification of the coupling approaches and a review of the coupled codes

open access: yesInternational Journal of Energy Research, 2020
Simulation is becoming increasingly important in the safety analysis of nuclear reactors nowadays. The physical phenomena in a nuclear power plant happen on three classified scales: system scale (phenomenon over the whole plant is concerned), component ...

Potential of application of IRT-T research reactor as the solution of the problem of graphite radwaste disposal [PDF]

open access: yesNuclear Energy and Technology, 2018
Aspects of handling irradiated graphite during decommissioning uranium-graphite reactors (UGR) of different types were investigated. It was demonstrated that handling reactor graphite is complicated by the presence in the composition of graphite of long ...

Interfacial Heat Transfer of Condensation Bubble with Consideration of Bubble Number Distribution in Subcooled Flow Boiling

open access: yesJournal of Thermal Science and Technology, 2013
For predicting the void fraction distribution in subcooled flow boiling, it is necessary to measure the interfacial heat transfer coefficient—which determines the amount of condensation rate of vapor bubble—with high accuracy.

Nuclear Data to Reduce Uncertainties in Reactor Antineutrino Measurements: Summary Report of the Workshop on Nuclear Data for Reactor Antineutrino Measurements (WoNDRAM) [PDF]

open access: yes, 2022
The large quantities of antineutrinos produced through the decay of fission fragments in nuclear reactors provide an opportunity to study the properties of these particles and investigate their use in reactor monitoring. The reactor antineutrino spectra are measured using specialized, large area detectors that detect antineutrinos through inverse beta ...

Accuracy Evaluation of Image Processing Method for the Measurement of Rising Bubble Volume in Stagnant Fluid

open access: yesJournal of Fluid Science and Technology, 2013
The measurement error when calculating the bubble volume by using image analysis was estimated by taking a single bubble of known volume (0.02 × 10-6-2.00 × 10-6 m3, or the volume equivalent diameter of 3.37-15.63 mm) and using a stereo ...

Testing of the ABBN-RF multigroup data library in photon transport calculations

open access: yesEPJ Web of Conferences, 2017
Gamma radiation is produced via both of nuclear fuel and shield materials. Photon interaction is known with appropriate accuracy, but secondary gamma ray production known much less. The purpose of this work is studying secondary gamma ray production data

Constraints on Hidden Photons Produced in Nuclear Reactors. [PDF]

open access: yesPhysical Review Letters, 2018
New light vector particles-hidden photons-are present in many extensions of the standard model of particle physics. They can be produced in nuclear reactors and registered by neutrino detectors.

Application of the Source-Jerk method using a neutron generator in a subcritical reactor

open access: yesActa Polytechnica, 2023
This paper describes the application of the Source-Jerk method using a neutron generator in the VR-1 reactor. The experiments were carried out on a shutdown reactor with subcriticality greater than -10 βeff.
