Nuclear reactors for marine propulsion and power generation systems

Nuclear power is currently not a commonly used option in commercial marine applications, despite its potential for significant emission reductions. This thesis is an overview of what has been done before, and what the potential is of modern marine nuclear power applications considering the long-term goals of harmful emission reduction in the...

Risk-based security assessment of transmission line overloading considering spatio-temporal dependence of load and wind power using vine copula

Location of wind power plants and demand centres are not always close by; hence, the transmission of energy puts a burden on existing grid infrastructure. This unwanted burden necessitates transmission lines to operate more and more frequently close to their operating limits. To alleviate such situations, this research addresses the advantages...

Numerical Study of Fluid Structure Interaction in Nuclear Reactor Applications

Flow-induced vibration (FIV) plays an important role in the nuclear industry. In nuclear power plants (NPP), the FIV may cause fatigue problems, stress corrosion cracking, possible failure modes and fretting wear. This in return can lead to nuclear safety issues and substantial stand-still costs due to unplanned outages. It is therefore...

Investment decisions under uncertainties: A case of nuclear power plants

This thesis discusses the role of flexibility of decisions when investing in projects that are affected by economic uncertainties. It uses the theory of real options to value such investment decisions. The thesis focuses on investment decisions related to nuclear power plants, which usually are affected by several sources of economic...

Nuclear Power and Justice between Generations. A Moral Analysis of Fuel Cycles

When we produce nuclear power we are depleting a non-renewable resource (uranium) that will eventually not be available to future generations. Furthermore the ensuing nuclear waste needs to be isolated from the biosphere for long periods of time to come. This gives rise to the problem of justice to posterity or intergenerational justice....
