The thermophysical performance and solid mechanics behavior of UO2-36.4vol % BeO fuel pellets cladded with Zircaloy, SiC, and FeCrAl, and Zircaloy cladding materials coated with SiC and FeCrAl, are investigated based on simulation results obtained by the CAMPUS code. In addition, the effect of coating thickness (0.5, 1 and 1.5 mm) on fuel performance and mechanical interaction is discussed. The...

The paper presents the results of studies on burning minor actinides (MA) extracted from SNF thermal reactors in a BN-600 reactor, which uses complete set MAs instead traditional nuclear fuel types: uranium and/or plutonium. advantages such approach to MA are that long-lived waste is recycled and energy produced can be used, e.g., generate electricity. Besides, where, reactor with or MOX used f...

Abstract In the past, 99m Tc produced by PT. Industri Nuklir Indonesia (PT. INUKI) was carried out through processing of a 99 Mo parent radioisotope that using high enriched uranium target. Due to restrictions on use high-enriched (HEU) International Atomic Energy Agency, INUKI has converted process low (LEU) This study aims determine change radioactive fission waste characteristics in producti...

The International Atomic Energy Agency (IAEA) requires that all test and research reactors operating on Higher Enriched Uranium (HEU) should be converted to Low (LEU) for safety security purposes. Nigeria having a Miniature Neutron Source Reactor (MNSR) has been long interested in fuel technological not just develop the area but also meet with resolution nuclear treaty set out by global regulat...

Fluid-fueled molten-salt reactors (MSRs) are actively being developed by several companies, with plans to deploy them internationally. The current IAEA inspection tools largely incompatible the unique design features of liquid fuel MSRs (e.g., complex chemistry, circulating inventory, bulk accountancy, and high radiation environment). For these reasons, safeguards for seen as challenging requir...

This paper discusses the development of and proposed enhancements to a colorimetric test for the detection of uranium in biological samples such as urine. The goal of this work is to develop a technique for the detection of uranium that could: 1) be conducted rapidly and accurately; 2) would not require extensive sample preparation; 3) would not require expensive or complicated instrumentation;...

For the purpose of developing the capability to produce fission Mo, the Chilean Nuclear Energy Commission is participating in the IAEA Coordinated Research Project: “Developing Techniques for Small Scale Indigenous Mo-99 Production using LEU Fission or Neutron Activation”. Fission Mo will be produced irradiating, at RECH-1 reactor, a target made of a LEU metallic uranium foil held between two c...
