The impact of neutronic safety parameters on SMART reactor dynamic response

Sarah Kamalpour; Hossein Khalafi

Volume 2, Issue 4 , December 2021, Pages 1-9

http://dx.doi.org/10.22034/rpe.2021.303359.1039

Abstract
  The neutronic safety parameters determine reactor dynamic response. These parameters change as a function of core inventory during reactor cycle. Therefore, assessment of reactor behavior throughout operational cycle is an important issue in reactor safety analysis for transients. The purpose of the ...  Read More

Relativistic Scattering Amplitude in the Pöschl-Teller Double Ring-Shaped Coulomb Potential

Mahdi Eshghi; Sasan Soudi; Sameer M. Khadir

Volume 2, Issue 4 , December 2021, Pages 11-18

http://dx.doi.org/10.22034/rpe.2021.307276.1043

Abstract
  The scattering problems, in the presence of an external potential field, have become highly interesting topics in relativistic and non-relativistic quantum mechanics. It is well known that the scattering of a relativistic particle in the field of a potential can be treated exactly by finding the continuum ...  Read More

Estimation of effective β-fraction of the VVER-1000 reactor in terms of exposure using DRAGON5/DONJON5

Omid Safarzadeh; Farahnaz Saadatian-Derakhshandeh

Volume 2, Issue 4 , December 2021, Pages 39-46

http://dx.doi.org/10.22034/rpe.2022.322754.1049

Abstract
  The effective β-fraction has a key role in the dynamic response of the reactor. This study aims to assess the suitability and accuracy of the detailed models of DRAGON5 and DONJON5 code for estimation of the effective fraction of delayed neutron for the VVER-1000 reactor core. DRAGON5 is adopted ...  Read More

Investigation of under-containment gamma dose after total core uncovering accident in Tehran Research Reactor

Ehsan Boustani; Mostafa Hassanzadeh; Rohollah Ahangari

Volume 2, Issue 4 , December 2021, Pages 47-56

http://dx.doi.org/10.22034/rpe.2022.321947.1048

Abstract
  The occurrence of core uncovering following a loss of coolant accident is conceivable and should be taken into account for its significant possible consequences. Source terms are calculated using ORIGEN 2.1 code, and the gamma dose of the uncovered core is calculated for three different normal and anticipated ...  Read More
