Corrosion monitoring and determination of aluminium fuel clad of Tehran Research Reactor (TRR)

Progress in Nuclear Energy, 2010
Abstract Aluminium alloys are used as cladding materials for fuel plates in many research reactors. In this work, which carried out in-pool tests corrosion surveillance coupons were used. Aluminium alloys and stainless steel had been coupons in form of circular disks were exposed to the pool water for six months.

Improving the NAA laboratory pneumatic transfer system for using Tehran research reactor

Annals of Nuclear Energy, 2008
Abstract Neutron activation analysis (NAA) is a precise multi-elemental method which performs well for qualitative and quantitative analyses. This method has been applied to the laboratory of Radiation Applications Research School (RARS) at University of Tehran.

Production of 223Ra from 226Ra in Tehran Research Reactor for treatment of bone metastases

Journal of Radioanalytical and Nuclear Chemistry, 2015
In this research production of 223Ra via neutron irradiation of 226Ra nuclei was studied in Tehran Research Reactor and compared with available literature data. Dowex 1X8 and Dowex 50WX8 anion and cation exchange resins were used for isolation of produced radioisotopes.

Gamma and neutron dosimetry of Tehran Research Reactor containment during and after LOCA accident

Applied Radiation and Isotopes, 2019
The radiation effects of loss of coolant accident on the reactor operators are critical issues. In the present study, computational codes were used to investigate gamma and neutron dose rates inside the 5 MW pool-type Tehran Research Reactor containment.

Computational investigation of isotopic signature of radioxenon released from Tehran research reactor

Journal of Radioanalytical and Nuclear Chemistry, 2016
This paper presents the early radioxenon emission inventory for Tehran research reactor (TRR) based on comparison of the two computational analyses of MCNPX2.6 and ORIGEN 2.1. To determine the possible xenon isotopic signature of TRR’s releases under normal operational condition, the TRR fresh fuel burn-up through a total 400 days operational reactor ...

Experimental measurements of Na-24 activity in Tehran Research Reactor (TRR)

Progress in Nuclear Energy, 2010
Abstract Experimental determination of coolant activity due to Na-24 produced as a result of 23 Na(n,γ) 24 Na and 27 Al(n,α) 24 Na reactions has been done for TRR. Activity of various water samples from the reactor pool was measured. Relative Source Strength Measurement (RSSM) technique was employed to measure Na-24 activity.
