Design and construction of a thermal neutron beam for BNCT at Tehran Research Reactor
Applied Radiation and Isotopes, 2014An irradiation facility has been designed and constructed at Tehran Research Reactor (TRR) for the treatment of shallow tumors using Boron Neutron Capture Therapy (BNCT). TRR has a thermal column which is about 3m in length with a wide square cross section of 1.2×1.2m(2). This facility is filled with removable graphite blocks.

A feasibility study of the Tehran research reactor as a neutron source for BNCT
Applied Radiation and Isotopes, 2014Investigation on the use of the Tehran Research Reactor (TRR) as a neutron source for Boron Neutron Capture Therapy (BNCT) has been performed by calculating and measuring energy spectrum and the spatial distribution of neutrons in all external irradiation facilities, including six beam tubes, thermal column, and the medical room.

BNCT project at Tehran Research Reactor: Current and prospective plans
Progress in Nuclear Energy, 2016Abstract Boron Neutron Capture Therapy (BNCT) for brain tumor treatment is under development at the Tehran Research Reactor (TRR). This paper presents all current research activities that were performed during recent years as well as the prospective of BNCT research at TRR. The theoretical and experimental investigations show that TRR has a very good

Cold neutron source conceptual designing for Tehran Research Reactor
Annals of Nuclear Energy, 2016Abstract A cold neutron source (CNS) conceptual designing for the Tehran Research Reactor (TRR) were carried out using MCNPX code. In this study, a horizontal beam tube of the core which has appropriate the highest thermal flux is selected and parametric analysis to choose the type and geometry of the moderator, and the required CNS dimensions for ...

A multi-moderator neutron spectrometer for use in BNCT studies of the Tehran research reactor
Applied Radiation and Isotopes, 2021The Tehran Research Reactor is the only appropriate and available neutron source in Iran for clinical boron neutron capture therapy (BNCT). One of the requirements for BNCT is to carefully evaluate and measure the therapeutic neutron beam (epithermal neutrons) as well as the fast and thermal neutron components for successful treatment. In this research,

Determination of Tehran Research Reactor power by 16N gamma detection
Annals of Nuclear Energy, 2011Abstract The radioisotope 16 N is produced by the interaction of fast neutrons with 16 O in water reactor coolant. This radioisotope emits at the two major gamma ray energies of 6.13 MeV and 7.1 MeV. Exploiting the linear relation between the number of gamma particles versus the reactor power change, the reactor power is determined by detecting and

Production and modeling of radioactive gold nanoparticles in Tehran research reactor
Applied Radiation and Isotopes, 2016Gold has two medically useful radioactive isotopes, 198Au and 199Au, for locally irradiating and killing tumor cells. 198Au radionuclide has been produced through the irradiation of the pure gold via 197Au(n,γ)198Au reaction in the Tehran Research Reactor at a thermal neutron flux of 4.5×1013ncm-2s-1 for the different irradiation times.
