1. 11. BWR In-Core Instrumentation Sensitivity to Material and Geometrical Distortions

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Mikael Nivala Fernberg; [2016]
   Keywords : ;

   Abstract : Several BWR utilities are adopting practices for determining the state of control rods based on the neutron sensitive LPRM and gamma sensitive TIP measurement systems of the nuclear reactor core. This method is in this study evaluated by quantitatively analyzing the detector sensitivity to several material and geometrical distortions in the detector vicinity, using the Los Alamos National Laboratory stochastic Monte Carlo code MCNP5 and the Westinghouse 3D core simulator POLCA7.

3. 12. Development of the endurance test program and the assembly fixture for TRITON11™

   University essay from Lunds universitet/Innovation

   Author : William Lundström; [2016]
   Keywords : Nuclear fuel; Boiling Water Reactor; fretting wear; test program; assembly fixture; Technology and Engineering;

   Abstract : The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. READ MORE

4. 13. Qualification of WestinghouseBWR lattice physics methods againstcritical experiments

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Kim Landelius; [2016]
   Keywords : HELIOS; PHOENIX5; lattice code;

   Abstract : This thesis is part of a larger qualification effortperformed at Westinghouse Electric Sweden AB of the PHOENIX5 latticephysics code. The aim of the thesis is to validate PHOENIX5 withregards to cold criticality tests performed at the Toshiba NCAfacility in 2010-2011. READ MORE

5. 14. Tomographic reconstruction of subchannel void measurements of nuclear fuel geometries

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Magnus Ahnesjö; [2015]
   Keywords : tomography; void; nucler power; bwr;

   Abstract : The Westinghouse FRIGG loop in Västerås, Sweden, has been used to study the distribution of steam in the coolant flow of nuclear fuel elements, which is known as the void distribution. For this purpose, electrically heated mock-ups of a quarter BWR fuel bundles in the SVEA-96 geometry were studied by means of gamma tomography in the late 1990s. READ MORE

6. 15. Validation and Benchmarking of Westinghouse BWR lattice physics methods

   University essay from KTH/Reaktorteknologi

   Author : Karol Luszczek; [2015]
   Keywords : Serpent; HELIOS; lattice physics; benchmarking; Monte Carlo; neutronics; reactor physics;

   Abstract : A lattice physics code is a vital tool, forming a base of reactor coreanalysis. It enables the neutronic properties of the fuel assembly to becalculated and generates a proper set of data to be used by a 3-D full coresimulator. READ MORE
