abstract uranium is a radioactive heavy metal. development of nuclear industries and application of phosphate fertilizers contain uranium impurity resulted in soil contamination with uranium. a pot experiment had been conducted under controlled condition. the experiment carried out in completely randomized design with two factors, including two plants (soybean and sunflower) and six levels of u...

The use of a lead slowing-down spectrometer (LSDS) is considered as a possible option for nondestructive assay of fissile material of used nuclear fuel. The primary objective is to quantify fissile isotopes, particularly 239Pu and 235U, via a direct measurement distinguishing them through their characteristic fission spectra in the LSDS. In this paper, we present several assay measurements perf...

The richest uranium ore bodies ever discovered (Cigar Lake and McArthur River) are presently under development in northeastern Saskatchewan. This subarctic region is also home to several operating uranium mines and aboriginal communities, partly dependent upon caribou for subsistence. Because of concerns over mining impacts and the efficient transfer of airborne radionuclides through the lichen...

Uranium silicide, U3Si2, is considered as an advanced nuclear fuel for commercial light water reactors with improved accident tolerance well competitive economics. Nd employed a local burnup indicator conventional oxide fuels due, among other reasons, to its low mobility in the UO2 matrix and high fission product yield. As part of studies necessary determine whether can be candidate U3Si2 conce...

Nuclear fission reactions produce a lot of radionuclides that release energy, one which is in the form gamma radiation. Gamma radiation produced by various types radionuclides, and nuclear reactor fuel will different values intensity. Uranium Molybdenum (U7Mo-Al) type for future research reactors possesses many advantages. For application molybdenum-based fuel, it necessary to determine resulti...

The ever-growing need for radiopharmaceuticals, i.e., compounds containing pharmaceutical drugs and radioisotopes used medical diagnostic imaging (SPECT/PET scan) treating neoplasms, is significantly leading to an increased demand such substances in hospitals clinics worldwide. Currently, most large-scale productions of required radiopharmaceuticals are carried out research reactors, via the fi...

During in reactor operations, the slowing down of fission fragments generates most radiation damage uranium dioxide. Fission deposit their energy to both atomic and electronic subsystems through nuclear interactions. To study possible synergistic effects deposition on microstructure, UO2 thin foils have been irradiated with 0.39 MeV Xe and/or 6 Si ions at 298 K using single or dual beam ion irr...
