6. Validation of the Westinghouse BWR nodal core simulator POLCA8 against Serpent2 reference results
University essay from KTH/FysikAbstract : 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.

7. Development of the endurance test program and the assembly fixture for TRITON11™
University essay from Lunds universitet/InnovationAbstract : 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

8. Control Rod Effect at Partial SCRAM : Upgrade of Plant Model for Forsmark 2 in BISON After Power Uprate
University essay from Uppsala universitet/Tillämpad kärnfysikAbstract : This study aims to improve the modeling of partial SCRAM in the BISON plant model for the Forsmark 2 nuclear reactor after power uprate. Validation of the BISON model against tests performed from March to May in 2013 have shown that this is one of the areas in which there is room for improvement. READ MORE

9. Influence of In-vessel Pressure and Corium Melt Properties on Global Vessel Wall Failure of Nordic-type BWRs
University essay from KTH/KärnkraftssäkerhetAbstract : The goal of the present study is to investigate the effect of different scenarios of core degradation in a Nordic-type BWR (boiling water reactor) on the reactor pressure vessel failure mode and timing. Specifically we consider the effects of (i) in-vessel pressure, (ii) melt properties. READ MORE

10. Transient behaviour in a BWR with Hafnium Cladding : Feasibility study of using BWRs as Higher Actinide Burners at the Example of Ringhals I
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Transmutation of transuranic elements is of interest to lower storage unit cost and long-term radiotoxicity. To make use of existing infrastructure, the deployment of Boiling Water Reactors (BWRs) with hafnium cladding and Mixed Oxide (MOX) fuel was proposed, resulting in a hardening of the neutron spectrum.
