Modification of the neutron beam spectrum for neutron radiography at Tehran Research Reactor (TRR)

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996
Abstract Recently due to the replacement of the High Enriched Uranium (HEU) fuel with the Low Enriched Uranium (LEU) fuel and the changes in the reactor core configuration at TRR, the existing Neutron Radiography (NR) system was no longer efficient.

Optimization of 60Co production using neutron flux trap in the Tehran research reactor

Annals of Nuclear Energy, 2005
Abstract Radioisotope production is one of the most important applications of research reactors. 60 Co has a wide application in industry and medicine. In this paper the efficient production of 60 Co by enhancing radiation systems is studied and developed by using neutron flux trap concept in Tehran research reactor.

Feasibility and improvement in production of 191Os/191mIr generator by Tehran Research Reactor (TRR)

Annals of Nuclear Energy, 2012
Abstract This manuscript describes an investigation on the production of 191 Os/ 191m Ir by Tehran Research Reactor (TRR). 191 Os-hexachloro-osmate was obtained by thermal neutron (4 × 10 13  cm −2  s −1 ) irradiation of enriched 190 Os sample followed by fusion with KOH and KNO 3 in acidic media. One of the important radionuclide impurities is

Integral boundary layer heat transfer modeling for Tehran Research Reactor

Progress in Nuclear Energy, 2011
Abstract In the present work the validity of applying the Boussinesq approximation in the analysis of natural convection heat transfer along nuclear fuel plates with large coolant channel aspect ratios is evaluated. The Boussinesq approximation is introduced into the integral boundary layer equations governing the system to describe the velocity and ...
