This thesis is a follow up on "SPARC fast reactor design: Design of two passively metal-fuelled sodium-cooled pool-type small modular fast reactors with Autonomous Reactivity Control" by Tobias Lindström (2015). In this thesis the two reactors designed by Lindström in said thesis were evaluated. The goal was to determine the reactors ability to load follow as well as the burnup of the neutron absorber used in the passive control system. To be able to determine the dynamic behaviour of the reactors the reactivity feedbacks of the cores were modelled using Serpent, a Monte Carlo simulation software for 3D neutron transport calculations. These feedbacks were then implemented into a dynamic simulation of the core, primary and secondary circulation and steam generator. The secondary circulation and feedwater flow were used to regulate steam temperature and turbine power. The core was left at constant coolant flow and no control rods were used. The simulations showed that the reactor was able to load follow between 100 % and 40 % of rated power at a speed of 6 % per minute. It was also shown that the reactor could safely adjust its power between 100 % and 10 % of rated power suggesting that load following is possible below 40 % of rated power but at a lower speed. Finally the reactors were allowed compensate for the variations in a week of the Latvian wind power production in order to show one possible application of the reactor.

The aim of this master thesis is to define fast fashion and fast fashion retailing, and describe specifics of their business activities with deep focus on the Czech market. The theoretical part reviews literature dealing with international strategy and management and fashion and fast fashion retailing. The empirical part then focuses on real-life business cases. In order to illustrate the behaviour of fast fashion retailers on the Czech market, a case study method is employed. The attention is narrowed on three chosen fast fashion retailers MANGO, Zara and H&M. The separate case studies on MANGO, Zara and H&M focus on retailers' presence in the Czech market. The retailers' position on the market and strategies are then compared with the aim to identify the most successful fast fashion retailer and verify whether the hypothesis that the first mover to the market gains the competitive advantage is true for the chosen fast fashion retailers in the Czech market. Further, the work tries to find possible factors of the retailers' success in the Czech market.
