Articles in Press, Accepted Manuscript, Available Online from 25 August 2022

https://doi.org/10.22034/rpe.2022.349750.1094

Abstract
  Neutron data and cross-sections are highly regarded and are essential for developing nuclear equipment such as advanced fission and fusion reactors, accelerators, neutron shielding, physics studies, etc. The neutron cross-section should preferably be measured using a single-energy neutron beam, although ...  Read More

Abstract
  Simulation work provides valuable information on the behavior of different research reactor neutron analysis facilities. The present study considered neutron and secondary-gamma dose rate variations by applying a sapphire crystal inside the D channel in Tehran Research Reactor (TRR). The MCNPX computational ...  Read More

The effect of the number of spent fuel casks on the dose of the outer part of the hall concrete wall

Zohreh Gholamzadeh; Ebrahim Abedi; Seyed Mohammad Mirvakili

Volume 2, Issue 3 , September 2021, , Pages 1-7

https://doi.org/10.22034/rpe.2021.296510.1033

Abstract
  The management of high radioactive spent nuclear fuel (SNF) from research and power reactors has become a key topic of discussion in the nuclear communities. Metal casks are used for the management and disposal of spent fuel and all types of radioactive waste worldwide. The spent fuel assemblies-contained ...  Read More

Investigation of the water to air conversion factor dependency to the spent fuel cooling time, irradiation history and burnup for gamma dose rate determination of TRR spent fuels

Zohreh Gholamzadeh; Rohollah Adeli; Mahdi Keivani

Volume 2, Issue 1 , January 2021, , Pages 1-7

https://doi.org/10.22034/rpe.2021.242746.1021

Abstract
  ‎Routine gamma dosimetry of spent fuels in nuclear power stations is mandatory to manage their storage in dry or wet spent fuel storages‎. ‎Mostly the spent fuel gamma dose rate measurements out of the spent fuel pool is impossible because of the high exposures of the operators‎. ‎Therefore‎, ...  Read More

Feasibility study of application of ThO2 fuel rods in VVER-1000 fuel assemblies using MCNP and ORIGEN codes

Zohreh Gholamzadeh; Atieh JozVaziri

Volume 2, Issue 1 , January 2021, , Pages 35-41

https://doi.org/10.22034/rpe.2021.242881.1022

Abstract
  ‎Thorium is more abundant in nature than uranium‎. ‎The fertile thorium fuel can breed to fissile U-233 by absorbing a neutron‎. ‎The produced fissile has good neutronic performance in both thermal and fast neutron spectra‎. ‎Many types of thorium-based fuels were applied ...  Read More

ThO2 spent fuel assembly’s gamma dose rate dependency to burnup and cooling time

Zohreh Gholamzadeh; Mohadeseh Gholshanian; Seyed Mohammad Mirvakili

Volume 1, Issue 3 , August 2020, , Pages 43-48

https://doi.org/10.22034/rpe.2020.104833

Abstract
  Today thorium based fuels are being investigated as an alternative fuel technology. However, the majority of thorium fuel research studies are limited to reactor physics investigations, which leaves a gap for dose evaluation and shielding concerns of such spent fuels. The present work investigates thorium ...  Read More
