Analysis of the control rod withdrawal speed impact on the transient behavior of Bushehr-1 NPP using Simulink software

Morteza Akbari; Farrokh Khoshahval

Volume 5, Issue 1 , January 2024, , Pages 63-74


  In this research, the governing dynamic equations of the Bushehr NPP core are studied and modeled using Matlab (Simulink) software. The point kinetic equation with the temperature feedbacks and the fuel-coolant energy balance equations in the time domain were used for this purpose. The model is validated ...  Read More

Volume 4, Issue 4 , October 2023, , Pages 1-6


  Polycarbonate-bismuth oxide composite has been used as a beta-ray sensor in the previous works. Calculation of two main quantities namely stopping power and range of electrons in this material can be useful to evaluate the optimal thickness of the sensor. Thus, in this study, the range of electrons and ...  Read More

Effect of reinforcement phase loading on the dosimetry response of a Polycarbonate/Bismuth Oxide nanocomposite for beta particles

Shahryar Malekie; Sedigheh Kashian; Seyed Musa Safdari; Morteza Akbari; Arjang Shahvar

Volume 3, Issue 2 , May 2022, , Pages 11-15


  In this experimental work, Polycarbonate/Bismuth Oxide (PC-Bi2O3) nanocomposites were prepared in various concentrations of 0, 10, 30, and 50 wt% with thicknesses of 1 mm and irradiated by a pure beta-emitter source of Sr-90. To fabricate the electrodes, copper sheets with thickness of 100 µm were ...  Read More
