“…A 3 MW TRIGA Mark II reactor was installed at the campus of Atomic Energy Research Establishment (AERE) of Bangladesh Atomic Energy Commission (BAEC) in Savar in 1986 [cf . 1,2]. It is a zirconium hydride moderated, light-water cooled and graphite (with Al cladding) reflected pulsing type reactor, designed for steady state operation at a thermal power of up *Author for correspondence (E-mail: md.shuzauddin@yahoo.com).…”

“…Since the shape and intensity of the neutron spectrum are strongly dependent on the irradiation position, it is absolutely necessary to know the exact location near the core of the reactor where the samples are to be irradiated. A well-defined position known as Dry Central Thimble (DCT), is available at the Savar reactor [1,2], and it was used in the present work. We would like to mention that we did not attempt to analyse the low energy part of the neutron spectrum which is very demanding, especially in the case of a TRIGA reactor.…”

Fast neutron spectrum unfolding of a TRIGA Mark II reactor and measurement of spectrum-averaged cross sections: integral tests of differential cross sections of neutron threshold reactions

Summary The spectrum of fast neutrons having energies from 0.5 to 20 MeV in the core of the 3MW TRIGA Mark II reactor at Savar, Dhaka, Bangladesh, was unfolded by activating several metal foils to induce threshold nuclear reactions covering the whole spectrum, and then doing necessary iterative calculations utilizing the activation results and the code SULSA. The analysed shape of the spectrum in the TRIGA core was found to be similar to that of the pure 235U-fission spectrum, except for the energies between 0.5 and 1.5 MeV, where it was slightly higher than the fission spectrum. Spectrum-averaged cross sections were determined by integral measurements. The integral values measured in this work were compared with the recommended values for a pure fission spectrum as well as with the integrated data deduced from measured and evaluated excitation functions of a few reactions given in some data files. The good agreement between integral measurements and integrated data in case of well-investigated reactions shows that the fast neutron field at the TRIGA Mark II reactor can be used for validation of evaluated data of neutron threshold reactions.

“…This study focused on the 3 MW TRIGA Mark II research reactor located in Savar, Dhaka. The facility uses a uranium-zirconium hybrid fuel moderated and light water-cooled system, which is used primarily for training and research in various fields, such as Neutron Activation Analysis (NAA), Neutron Radiography (NRG), Neutron Scattering (NS), and production of radioisotopes ( 131 I, 99 mTc, 46 Sc) for medical applications [19][20][21][22]. The meteorological observations at the site show that wind predominantly flows from the south (S) direction is dominant (Figure 2).…”

This work is a contribution to the assessment of the radiological consequences of radioactivity and radiation dose for TRIGA Mark II research reactor during continuous operation. The potential release to the atmosphere of 131I, 137Cs, and 90Sr are computed in the South direction is calculated using CROM software. We have attempted to evaluate the daily concentration of radioactivity and its impact on foodstuff. The annual average dose received from internal and external irradiation by age group through the different pathways were also considered. The simulation results showed that the highest air concentration was found at 225 m distance from the source and the calculated doses were found to be significantly very low. The contribution of Iodine 131I is significantly higher in fruit vegetables, while the 137Cs and 90Sr are dominant in animal products. Furthermore, inhalation and ingestion of contaminated food were found to be the most likely routes of entry into the human body.
