    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Johannes Ekman; [2021]
    Keywords : calorimetry; calorimeter; System 251; temperature evolution; spent nuclear fuel; SNF; MATLAB; SERPENT2; Clab; nuclear decay heat; calibration measurements; thermodynamic model; gamma escape fraction; mass correction; calibration measurements; electric heater; three component system; system of ordinary differential equations; eigenvalues; eigenvalue estimation; temperature increase method; polynomial approximation of mass correction; sensitivity of mass correction; calorimeter heat capacity; mass correction uncertainty; calorimeter calibration curve; monoenergetic gamma spectrum; curve fitting of temperature as function of time;

    Abstract : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. READ MORE

  3. 2. Small-Scale Biogas Upgrading System Modeling Tool Development

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : David Saldarriaga; [2018]
    Keywords : ;

    Abstract : The potential of biogas to decarbonize society depends partially on the success of small-scale systems. Two specific locations where biogas units can be implemented are considered in this study: small farms and small isolated populations. READ MORE

  4. 3. Development of a multi-collector inductively coupled plasma massspectrometry method for measurement of stable sulphur isotope ratios in aerosol sulphate

    University essay from Uppsala universitet/Analytisk kemi

    Author : Katerina Rodiouchkina; [2018]
    Keywords : Sulphate aerosol; isotope ratio; sulphur isotope; δ34S and δ33S measurements; MC-ICP-MS; method development; inter-laboratory comparison;

    Abstract : Sulphur stable isotope ratios are useful tracers in geological and environmental studies. They can for example be used to trace the origin of atmospheric sulphate aerosols, because anthropogenic sulphate and natural sulphate have distinguishable δ34S-values (δ34S value of approximately +0 to +8 ‰ for anthropogenic and approximately +12 to +19 ‰ for natural).

  5. 4. Estimation of In-cylinder Trapped Gas Mass and Composition

    University essay from Linköpings universitet/Fordonssystem

    Author : Sepideh Nikkar; [2017]
    Keywords : Diesel Engine; Cylinder Pressure; Residual Gas Mass; Gas Mass Composition; Cylinder Wall Temperature; Cylinder Pressure Correction;

    Abstract : To meet the constantly restricting emission regulations and develop better strategiesfor engine control systems, thorough knowledge of engine behavior is crucial.One of the characteristics to evaluate engine performance and its capabilityfor power generation is in-cylinder pressure.
