6. Mathematical modelling of Degussa Furnace
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The energy demands in the world is rapidly increasing and with this, a supply nuclear power is of much interest. Nuclear fuel is relatively efficient when comparing to power sources like wind and hydropower plants. LÄS MER
7. Validation of the Westinghouse BWR nodal core simulator POLCA8 against Serpent2 reference results
Master-uppsats, KTH/FysikSammanfattning : When a new nodal core simulator is developed, like all other simulators, it must go through an extensive verification and validation effort where, in the first stage, it will be tested against appropriate reference tools in various theoretical benchmark problems. The series of tests consist of comparing several geometries, from the simplest to the most complex, by simulating them with the nodal core simulator developed and with some higher order solver representing the reference solution, in this case on the Serpent2 Monte Carlo transport code.

8. Improved methodology for postulated fuel handling accident
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/HållfasthetsläraSammanfattning : This report presents a suggestion of an improved method for evaluation of a fuel handling accidents. Using a 3D FE-model and ANSYS LS-DYNA EXT the structural analysis is carried out. Importing geometry from SpaceClaim and simplifying it creates the geometry used in this analysis. LÄS MER
9. Joint Calibration of a Cladding Oxidation and a Hydrogen Pick-up Model for Westinghouse Electric Sweden AB
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Knowledge regarding a nuclear power plants potential and limitations is of utmost importance when working in the nuclear field. One way to extend the knowledge is using fuel performance codes that to its best ability mimics the real-world phenomena. LÄS MER
10. Application of sub-channel thermal-hydraulic analysis to core calculations with POLCA8 and VIPRE-W
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysikSammanfattning : This report investigates the steps of a one-way coupling between two simulation codes developed by Wesinghouse Electric Sweden AB. The Westinghouse POLCA8 is a three dimensional steady-state diffusion theory code used for simulating the neutronic, thermal and hydraulic behavior of a reactor core. LÄS MER
