Forsmark 3 ?Ett Framtida Biobränslekraftverk?
Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant. This was calculated to 8,24 MJ/kWh. The total heatrequired together with the fuel-data, resulted in the amount of fuel required.Since the energy content of biomass fuel is far less than that of uranium, massive amounts offuel have to be used to be able to produce the same amount of electricity.As a consequence, the logistics and handling costs for biomass fuels are quite high andundeniably affect the investment cost.Electricity, fuel and so-called electricity certificates prices were modeled and forecasted inorder to calculate the annual income and expenses over the project time period.Investment costs for the project were calculated to 10,86 billion SEK and the pay-back timewas estimated to 8 years. Study findings show that such an investment would provide a totalreturn of 22.5 billion SEK.
