Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft. / The prospects for a parallel generation IV reactor in the swedish nuclear system.Eriksson, Moa January 2013 (has links)
A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced. In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios. By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor. The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor. The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal. Further this means an increase of the decay heat with 1,2MW. To decide whether or not it is possible to run a sodium-cooled fast reactor paral-lel with a light water reactor to compensate for the produced decay heat and fuel assemblies, further investigations concerning the deposit in the repository needs to be done.

Vill nästa generation bli chefer? : En kvantitativ studie om studenters attityd till ett framtida chefskap.Simon, Hjärtberg, Lundmark, Jonas January 2014 (has links)
På grund av stora pensionsavgångar står arbetsmarknaden inför en generationsväxling. Detta kommer att påverka dagens chefspositioner, och innebär att när äldre chefer pensioneras blir behovet av nya chefer allt större. Syftet med den här studien var dels att undersöka hur nästa generations arbetskraftser på att i framtiden inta en chefsposition och även om det finns vissa delar av chefskapet som de är mer positivt respektive negativt inställda till. Studien baserades på en enkätstudie där studenter från personalvetarprogrammet och civilingenjörsprogrammet vid Umeå universitet fick skatta ett antal påstående gällande chefskap. Resultatet visade att chefsattityden generellt sett var positiv för respondenterna, dock ville endast ett fåtal bli chef så snart som möjligt av sin karriär. Bland de som hade en negativ inställning till att bli chef framstod kravet att ha ansvar som den främsta anledningentill detta. Det framkom även en viss skillnad mellan programtillhörigheterna, där personalvetarstudenter tenderade att ha en positivare attityd till att bli chef än civilingenjörsstudenter.
