Bangladesh is committed to the peaceful use of atomic energy and has signed all protocols and additional protocol of the International Atomic Energy Agency (IAEA) in this regards. Bangladesh is operating nuclear facilities using radioisotopes, sealed radioactive sources (SRS) and generating radioactive wastes including spent SRS. This paper mainly focuses on the safe management of spent SRS gen...

Maisiagala RADON type radioactive waste storage facility was commissioned in 1963 in a marshy, ecologically sensitive locality, where soluble radionuclides easily can penetrate and migrate with groundwater. To assure the requirements of radiation safety, the analysis of radionuclide leakage from the radioactive waste storage facility is performed continuously. H (tritium, T1/2=12.33 years) is o...

Control decisions for gas storage facilities are made in the face of extreme uncertainty over future natural gas prices on world markets. We examine the problem faced by owners of storage contracts of how to manage the injection/withdrawal schedule of gas, given past price behavior and a predictive model of future prices. Real options theory provides a framework for making such decisions. We de...

The inevitable depletion of mineral resources, the constant deterioration of the geological and mining conditions for the development of mineral deposits and the restoration of raw materials from mining waste by recycling are all urgent problems we face today. The solution to this problem may ensure: a considerable extension of raw material source; decrease of investments in opening new deposit...

Although facility scale thermal energy storage of sensible heat in the range of 200-550°C has achieved a high maturity, state-ofthe-art approaches are still not very cost effective. An innovative storage concept is thus proposed that avoids the two major costdriving factors of the concrete storage and 2-tank molten salt systems. First, the storage volume is comprised of low-cost sensible storag...

Abstract Tailings formed during the mining and beneficiation of iron ore are sources intensive dust generation. In order to assess intensity formation determine effectiveness methods its reduction, it is necessary know local velocity air flow near various surfaces tailings storage facility. For theoretical solution this problem, a CFD model was developed, which allows determining field when flo...
