Investigation of efficient 131I production from natural uranium at Tehran research reactor

Annals of Nuclear Energy, 2005
Abstract Iodine-131, which has a half-life of 8.05 days, is the one of the most widely used radionuclides in medical diagnosis and treats some diseases of thyroid gland. Optimization of 131I production in Tehran research reactor (TRR) was studied by two different methods.

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.

Estimating decay heat removal rate by natural convection for Tehran Research Reactor

Progress in Nuclear Energy, 2012
Abstract An integral boundary layer model is developed in that both the Boussinesq and non-Boussinesq approximations are taken into consideration. The model analyzes laminar free convection between nuclear fuel plates having large aspect ratio. The coolant channels are subject to a uniform as well as non-uniform, symmetric, heat flux and varying ...

Effective delayed neutron fraction and prompt neutron lifetime of Tehran research reactor

Annals of Nuclear Energy, 2003
Computer codes Wims-D4 and Citation used for calculations of effective delayed neutron fractions βeff and prompt neutron lifetime (Λ) for both HEU and LEU fuel elements of the Tehran research reactor (TRR). Calculations have been performed for two states of the cold clean and hot core configuration.
