2. BWR Reactor Fuel Channel Manufacturing Simulations
University essay from KTH/HållfasthetsläraAbstract : Fuel channels are used to keep the components of a nuclear fuel bundle in place. The fuel channel of a new nuclear fuel which is being developed at Westinghouse has a complex geometry which creates challenges in the manufacturing process. FE simulations were developed of a two-stage forming process of the fuel channel. READ MORE

4. Nuclear Fuel Bundle Design Optimization using a Simplex Method
University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenAbstract : A strategy for nuclear fuel bundle design optimization in boiling water reactors(BWRs), using a simplex method, is presented and examined. The objective of the study is to see how an automatic optimization scheme can create nuclear designs for use in BWR fuel bundles and how the scheme can be improved. READ MORE
