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

  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

Second order average current nodal expansion method for time-dependent neutron diffusion simulation

Kambiz Valavi; Ali Pazirandeh; Gholamreza Jahanfarnia

Volume 2, Issue 3 , September 2021, Pages 9-15

  In the present work, a time-dependent neutron diffusion simulator is developed utilizing the second order of average current nodal expansion method. Generally, nodal methods can accurately simulate the reactor core with coarse meshes as long as the sizes of a fuel assembly. In this case, an adopted iterative ...  Read More

Investigation of the Effect of Insulator Sleeves on the Ion Emission in a 4kJ Plasma Focus Device

Saeideh Koohestani; Morteza Habibi; Azimeh NV Dehkordi

Volume 2, Issue 3 , September 2021, Pages 17-23

  For configuring plasma focus device (PFD), the gap between electrodes is filled out with a gas at low pressure. When discharge is starting at the surface of the insulator, the gas breaks down, leading to the flow of the plasma current sheath toward the anode end. A homogeneous and symmetric current sheath ...  Read More

Dimensional analysis of high gradient RF cavity considering shrink-fit construction method

Mahdi Aghayan; S. Farhad Masoudi; Farshad Ghgasemi; Hamed Shaker

Volume 2, Issue 3 , September 2021, Pages 25-30

  Advantage of non-brazing methods in manufacturing of cavities has been considered in high gradient studies because of the softening of copper by brazing cavities at high temperatures. Recent studies with hard copper cavities have been shown that the harder materials can reach larger accelerating gradients ...  Read More

Modeling the partial loss of coolant flow accident in the Super-critical water reactor

Mohammad Hossein Bahrevar; Gholamreza Jahanfarnia; Ali Pazirandeh; Mohsen Shayesteh

Volume 2, Issue 3 , September 2021, Pages 31-39

  In this study, thermal-hydraulic analysis of partial loss of coolant flow accident in supercritical pressure light water reactor (SCWR) with a new geometric design has been investigated. In the new design, the coolant and moderator circuits are separated. This analysis was performed using the development ...  Read More

Design a two-dimensional alpha surface contamination monitoring system using micro-pattern gaseous detectors (MPGDs)

Mohsen Mirhabibi; Maryam Najibzadeh; Ali Negarestani; Ahmad Akhound

Volume 2, Issue 3 , September 2021, Pages 41-44

  Addressed herein, a new monitoring method for alpha surface contamination based on the function of a thick gaseous electron multiplier (THGEM) in a self-quenching streamer mode (SQS) has been introduced. SQS mode detectors can detect alpha surface contamination in two dimensions. In the current study, ...  Read More
