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 ...

Hydraulic transient simulation of primary cooling circuit in Egyptian second research reactor

open access: yesJournal of King Saud University: Engineering Sciences, 2022
Hydraulic transient is a flow situation where the velocity of the flow and the pressure change rapidly with time in pipes networks filled with fluid. Water hammer is one of the consequences that may occur accidentally in the reactors cooling system.

Neutrino Oscillation Experiments at Nuclear Reactors [PDF]

open access: yes, 1999
In this paper I give an overview of the status of neutrino oscillation experiments performed using nuclear reactors as sources of neutrinos. I review the present generation of experiments (Chooz and Palo Verde) with baselines of about 1 km as well as the

Power upgrading of WWR-S research reactor using plate-type fuel elements part I: Steady-state thermal-hydraulic analysis (forced convection cooling mode)

open access: yesNuclear Engineering and Technology, 2020
The design of a nuclear reactor core requires basic thermal-hydraulic information concerning the heat transfer regime at which onset of nucleate boiling (ONB) will occur, the pressure drop and flow rate through the reactor core, the temperature and power

Neutron capture cross section and capture gamma-ray spectra of 138Ba in the keV-neutron energy region

open access: yesEPJ Web of Conferences, 2015
The neutron capture cross sections and the capture γ-ray spectra of 138Ba were measured in the astrophysically important energy region. Measurements were made at neutron energies from 15 to 80 keV.

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.

Geometry Optimization of Dispersed UMo Fuel for Light Water Reactors

open access: yesNuclear Engineering and Technology, 2023
The Uranium/Molybdenum metallic fuel has been proposed as promising advanced fuel concept especially in the dispersed fuel geometry. The fuel is manufactured in the form of small fuel droplets (particles) placed in a fuel pin covered by a matrix.

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

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.
