The Journal of Nuclear Energy Science & Power Generation Technology is a Hybrid Journal, giving author the choice of both Open Access and Subscription based publication.

JNPGT is a peer reviewed journal that accepts research, review articles, technical notes, commentary, mini reviews, scientific reports, thesis and online letters to editor, opinions on current topics and brief comments on previously published articles or other relevant findings in all major themes pertaining to Nuclear Energy Research and Nuclear Power Generation Technology. JNPGT is indexed in Chemical Abstracts Service (CAS) and in other major indexing services.

Aim and Scope: The Journal of Nuclear Energy Science & Power Generation Technology does not limit but emphasises on topics such as Nuclear Energy Research, Nuclear Engineering, Nuclear Materials & Fuel Research, Applied Nuclear Chemistry, Reactor Engineering & Design, Nuclear Thermal Hydraulics, Nuclear Instruments and Methods, Nuclear Waste Management, Radiological Safety Analysis, Reactor Construction, Nuclear Energy Policy, Radiation Measurement and Exposure Control, Fusion and Plasma Energy Research.

The journal also extends to Nuclear Technology Management, Nuclear Security & Nuclear Decommissioning, Disposal of Radioactive Waste, Emergency Preparedness & Response and Global Safety Concern.

Journal of Nuclear Energy Science & Power Generation Technology will be focussing on Nuclear Instruments and Methods for its upcoming issue. You are requested to mail us your manuscripts at editor.jnpgt@scitechnol.com / editor.jnpgt@scitechnol.net or SUBMIT ONLINE.

Articles submitted by authors are evaluated on Editorial Manager® System by a group of peer review experts in the field and it is ensured that the published articles are of high quality, reflect solid scholarship, and the information they contain is accurate and reliable. Authors may submit manuscripts and track their progress through the system. Reviewers can download manuscripts and submit their opinions and comments to the editor. Editors can manage the whole submission, review, revision and publishing process online.

Modelling the Velocity Profile of Coolant Flow in the GHARR-1 Fuel Channel

The velocity profile of coolant flow in the Ghana Research Reactor-1 (GHARR-1) fuel channel has been determined using a mathematical model based on Navier-Stokes equation. A finite difference scheme for the discretization by Marker and Cell (MAC) method was used in the model. Solution algorithms were developed and MATLAB program implemented to simulate the velocity distribution of coolant flow at a 30 kW nominal power. The fluid dynamics module of the Navier- Stokes equation in COMSOL Multiphysics v 3.4 was used to verify and validate the results obtained. The results showed a velocity distributions range of 0.9 m/s to 1.9 m/s. Reynolds number values ranging from 460 to 970 were also obtained indicating a laminar flow of coolant.

Observation of Gamma Rays from Water Activated by D-T Fusion Neutrons

In this paper, the activation of light water was discussed focusing on 6.13 MeV gamma-rays from 16N. observation of emitted gammarays were carried out using an optimized setup that consists of a closed water loop including a D-T neutron generator, a spiral water pipe in the irradiation region and a shielding measurement area with a gamma-ray detecting system. The gamma-rays detecting system incorporate large volume BGO detector (φ 12.5 x 5 cm). The obtained gamma-ray spectra are given for different water rates and corresponding to different irradiation and decay times. These spectra confirm that the decay gamma-rays from 16N appearing in activated water were really observed by the proposed setup.

Helium Induced Reduction of the Grain-Boundary Tensile Strength in Tungsten

We perform an experimental investigation and computer modeling of the influence of the heliu m segregation on the inherent strength of high-angle grain boundaries in tungsten, which is a promising plasma-facing material in nuclear fusion devices. Tensile tests of tungsten bicrystals were conducted inside a field-ion microscope by means of high-field mechanical loading. It is shown that the intergranular helium adsorption induces reduction of the inherent grain-boundary tensile strength.
