Nuclear power and high sea water temperatures (pdf 0.5 MB)
This text addresses the deliberate reduction of reactor power performed when sea water temperatures become unusually high. It would be possible to adapt the reactors so that they may be operated at full power even when the sea warms. The reason for the existing temperature limitations is the economic optimisation on which the design of the reactor has been based. The cost of occasional production losses on warm summer days has been weighed against the increased costs of designing the plant for high sea water temperatures. Read the full text here.

Climate impact of four closed reactors (pdf 0.08 MB)
The announced decisions by Vattenfall and Eon about premature closure of four reactors at the Swedish nuclear power plants Ringhals and Oskarshamn will result in an increased use of electricity generated from fossil fuels in neighbouring countries. Here the climate impact is calculated from a few simple assumptions, and the results are compared with other emissions.
