To which extent does the choice of nuclear energy contribute to adequate investment in power generation capacity? To which extent does the choice of nuclear energy improve the functioning of power systems and transmission infrastructures? The previously mentioned joint IEA/NEA (2010) study provides some general information on the LCOE per MWh for different technologies.27 Table 1.1 shows that nuclear energy is a very attractive option at interest rates that are below or only slightly above 5% real. They thus indicate the discounted average (unit) cost of production.
