1. 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 , Winter 2021, Pages 1-7

  ‎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

2. Feasibility study of Mo-99 production using high-power electron Linac: Nuclear and thermal-mechanical analysis based on photoneutron interaction

Faezeh Rahmani; Ali Taaghibi Khotbesara; Farshad Ghasemi

Volume 2, Issue 1 , Winter 2021, Pages 9-17

  ‎This work presents an alternative method for Mo-99 production as a parent nuclide of Tc-99m which is the most used radioisotope in diagnostic imaging processes‎. ‎Regarding to some benefits of accelerator-based methods over reactor-based methods for Mo-99 production‎, ‎the electron ...  Read More

Volume 2, Issue 1 , Winter 2021, Pages 27-33

  Radioactive stents loaded with I-125 seeds have been widely used for the treatment of advanced esophageal cancer. Understanding the dose distribution of such stents before the clinical use is essential. This study provides a dosimetric investigation of I-125 seed-loaded stents based on the seed's arrangement ...  Read More

5. 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 , Winter 2021, Pages 35-41

  ‎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
