Abstract

PROLIFERATION RESISTANCE ASSESSMENT OF INDONESIAN 10-MWT RDE EXPERIMENTAL POWER REACTOR USING INPRO METHODOLOGY. Assessment of proliferation resistance (PR) for 10-MWt RDE has been conducted to verify the RDE safeguards desain. Proliferation resistance (PR) is a parameter that can be used to measure the ability of a facility to implement safeguards (safeguardability). Safeguards is every technical measure used to ensure that every nuclear material in a facility is used as declared and only for welfare. Proliferation resistance of 10-MWt RDE has been assessed with INPRO methodology. The areas assessed were specific to intrinsic features of RDE, which consist of the attractiveness of nuclear material and technology and also detectability and chances of diversion of the nuclear material. This assessment concludes that the 10-MWt RDE has strong proliferation resistance, which indicates that the facility has small ability to diverse nuclear material and will less likely be used to proliferate nuclear weapon.

Abstract

EFFECTS OF COLD-ROLLING AND ANNEALING ON THE MICROSTRUCTURE AND MICROHARDNESS CHARACTERISTICS OF Zr-0.5%Nb-Si. The performance improvement of zirconium alloys can be done by adding a certain percentage of common alloying elements such as Nb and Si. The addition of Nb provides resistance to irradiation and stabilizes the β phase (which normally forms at high temperatures) at room temperature. The addition of Si increases the strength of the alloys. The synthesis of a Zr-0.5% Nb-Si alloy have been carried out using an electric arc furnace. The microstructure and the microhardness of this alloy were observed after cold-rolling and annealing. It can be seen from the annealed alloy without cold-rolling that the grain size is larger with reduced microhardnes. The alloy treated with cold-rolling shows changes in the microstructure while the deformation density increases, which results in an increase in microhardness. Heat treatment to the cold-rolled alloy changes the microstructure of the alloy where recrystallization occurs, and the deformation density decreases, which results in the decreasing of microhardness. The lowest grain size and microhardness for the alloy that was cold-rolled at ε = 0.8 and annealed are 0.302 mm and 187 HVN, respectively.
