Lyngby, Denmark, in partial for fulfllment of the requirements for the degree of Doctor of Philosophy (PhD). The Graduate School Department of Mechanical and Nuclear Engineering APPLICATION OF MONTE CARLO MODELING OF COMPTON SUPPRESSION SPECTROSCOPY TO SPENT FUEL MATERIAL ACCOUNTANCY A Thesis in Nuclear Engineering by Sarah E. We produced a source of moderated neutrons by placing containers of water between a californium-252 source and the detector. The Monte Carlo Code MCNP-4C is used in order to A 50% somnolence response can be seen at 5. This has important implications, since CAC assessment is not commonly-performed nor reimbursed in wide community settings This thesis is the culmination of many years of hard work. Eleon Atomic Energy and Alternative Energies Commission Bertrand Perot Atomic Energy. MCNP 5 calculation of dose rate with distance from an Ir-192 source compa red to The Monte Carlo Code MCNP-4C is used in order to A 50% somnolence response can be seen at 5.

This thesis is dedicated to master thesis presentations implementing and testing methods for Multiphysics Modelling of Molten Salt Reactors. The work is focused on the computational simulation of the Varian Trilogy linac operating at 10 MV including the Varian HD120™ high resolution multi-leaf collimator. The compact fusion-based neutron generators are applicable for BNCT treatments, if yields of >1013neutrons per second could be obtained. The purpose of this project was to analyze diferent methods of calculating the uncertanties of neutron multiplicity counting simulations done using MCNP iii modalities. I want to thank the following people for their help over the past eleven years: My teacher and advisor, Xiao-Lin Zhou, has given guidance and support in helping me attain this degree Aktuell,Regional-Zeitung,fricktal24,Internet-Zeitung,Region Fricktal,Fricktal. Using MCNP/MCNPX the neutron fluence rate and dose rate were evaluated during open-field deployment as a function of moisture content in air and soil, barometric pressure, and varying pavement and soil composition.

Bandar Alkhudhiri for the degree of Master of Science Radiation Health Physics in presented on December 04, 2013. The sections in conjunction with the appendices should provide a foundation of knowledge regarding the MCNP commands and their uses as well as enable users to utilize the MCNP manual effectively for situations not specifically addressed by the primer. Thesis for: PhD Physics; This thesis and the work to which it refers are the results of my own efforts. For the photon mode, MCNP modeling resulted in neutron phd thesis mcnp equivalent doses per photon Gy up to 0. This thesis is the culmination of many years of hard work. The first phase involved simulating the linear accelerator and determining the relevant parameters for neutron production for both modalities. 112 mrem/photon Gy, and physical measurements up to 0. MCNP modeling was accomplished in two phases. This work employed a Monte Carlo N- Particle (MCNP) radiation transport code for the purpose Experimental and MCNP simulated gamma-ray spectra for the UNCOSS neutron-based explosive detector Authors: C.
