1. Calculation of neutronic and kinetic parameters of Isfahan Miniature Neutron Source Reactor using slope fit and perturbation methods

Mahdi Ghaed Rahmati; Mostafa hasanzadeh; Seyed Amir Hossein Feghhi

Volume 1, Issue 4 , Autumn 2020, Pages 1-8

http://dx.doi.org/10.22034/rpe.2020.104838

Abstract
  Kinetic and neutronic parameters play an important role in analysis of reactors dynamic behavior. Some of these parameters include: effective multiplication factor (keff), reactivity (ρ), neutron flux as well as power spatial distributions, effective delayed neutron fraction (βeff) and prompt ...  Read More

2. Differentiation method for Compton edge characterization in organic scintillation detectors

‎Mohammad Javad Safari

Volume 1, Issue 4 , Autumn 2020, Pages 9-16

http://dx.doi.org/10.22034/rpe.2020.104839

Abstract
  ‎It is well-known that response function of organic scintillation detectors does not appear with photopeaks‎. ‎Instead‎, ‎their dominant feature is a continuum‎, ‎usually called the Compton edge that innately exposes the resolution characteristics of detection system‎. ...  Read More

4. A review of advanced SMRs particularly iPWRs regarding safety features‎, ‎economy issues‎, ‎innovative concepts‎, ‎and multi-purpose deployment

Afshin Hedayat

Volume 1, Issue 4 , Autumn 2020, Pages 29-53

http://dx.doi.org/10.22034/rpe.2020.104841

Abstract
  ‎Both of small and medium sized reactors and small modular reactors are called SMRs‎. ‎They are reviewed and discussed in this paper‎, ‎particularly integral Pressurized Water Reactors (iPWRs)‎. ‎Studies show that PWRs are the most interested‎, ‎designed and constructed ...  Read More

5. Bohr Hamiltonian and interplay between γ-stable and γ-rigid collective motions with both Harmonic oscillation and Ring-shaped potentials for the γ-part.

Nahid Sohebi; Mahdi Eshghi; Majid Hamzavi; Mohsen Bigdeli

Volume 1, Issue 4 , Autumn 2020, Pages 55-64

http://dx.doi.org/10.22034/rpe.2020.104842

Abstract
  ‎In the present work‎, ‎the eigenvalue and eigenvector has been obtained by the Bohr Hamiltonian for even-even nuclei‎. ‎The competition between γ-stable and γ-rigid collective motions has been created in the presence of the rigidity parameter‎. ‎The β-part ...  Read More

6. Conceptual design of a high-performance hybrid object for applications of the fast neutron irradiation in MTRs

Afshin Hedayat

Volume 1, Issue 4 , Autumn 2020, Pages 65-76

http://dx.doi.org/10.22034/rpe.2020.104843

Abstract
  ‎Fast neutron irradiation is one of the most strategic radiation applications of research reactors‎. ‎Usually‎, ‎it is performed around the reactor core containing lower neutron flux‎. ‎In this paper‎, ‎a hybrid object has been introduced and analyzed to enhance irradiating ...  Read More
