  1. 1. Deposition of Zr(C,N) Coatings by Chemical Vapour Deposition

    University essay from KTH/Materialvetenskap

    Author : Linn Efsing; [2015]
    Keywords : Zr C; N ; MTCVD; Milling inserts; Coating; Growth rate; Microstructure; Texture coefficients;

    Abstract : In this master thesis the influence from process parameters within the Chemical vapour deposition process for a Zirconium Carbon-Nitride coating was investigated regarding growth rate, microstructure and texture. The interest in utilizing Zirconium Carbon-Nitride (Zr(C,N)) is due to its low coefficient of thermal expansion (CTE) relative the currently commonly used wear resistant coatings of Titanium-Carbon-Nitride (Ti(C,N)).

    University essay from KTH/Reaktorfysik

    Author : Boel Morenius; Timothy Ekelund; [2013]
    Keywords : ;

    Abstract : This report describes the process of a Bachelor thesis project conducted by two students at the KTH Royal Institute of Technology in Stockholm, Sweden. The project consists of establishing a functioning etching method for enhancing the visibility of grain structure in uranium nitride ( ) and uranium-zirconium nitride ( ). READ MORE

  4. 3. Development of a (U-Zr)N-Fuel Synthesis Control and Data Acquisition Program in LabVIEW

    University essay from KTH/Reaktorfysik

    Author : Gustaf Holst; Ludvig Thorsen; [2013]
    Keywords : ;

    Abstract : In this thesis, software for control and data acquisition was developed. The main purpose of the software is to provide overview and control of uranium and zirconium nitride syntheses. This includes connecting multiple gas flow controllers and a furnace to the software via a DAQ-module. READ MORE

  5. 4. Metallic residues after hydriding of zirconium

    University essay from KTH/Materialvetenskap

    Author : Patrik Andersson; Carl-Magnus Arvhult; [2012]
    Keywords : zirconium hydride; ZrH; nuclear fuel; nitride; metallic residues; hydriding; hydrogenation;

    Abstract : As a part of the production of nitride nuclear fuel for use in fast nuclear reactors, zirconium is hydrided followed by nitriding and mixing with uranium nitride. This work concludes a study of unwanted metallic particles present in a powder that is supposed to be a zirconium hydride. READ MORE

  6. 5. Manufacturing methods for (U-Zr)N-fuels

    University essay from KTH/Fysik

    Author : Tobias Hollmer; [2011]
    Keywords : nuclear fuel; nitride fuel; uranium nitride; zirconium nitride; spark plasma sintering; solid solution; reaction kinetics; hydriding; nitriding; denitriding; uranium hydride; zirconium hydride; uranium zirconium alloy;

    Abstract : In this work a manufacturing method for UN, ZrN and (U,Zr)N pellets was established at the nuclear fuel laboratory at KTH Stockholm/Sweden, which consists of the production of nitride powders and their sintering into pellets by spark plasma sintering. The nitride powders were produced by the hydriding-nitriding route using pure metal as starting material. READ MORE
