Is the use of nuclear energy ethically justifiable?

If one wants to try and attain, in a responsible manner, the objective of future energy supply, which consists in meeting, to a satisfactory degree, the humanly adequate demands of a growing population for energy by means of a good and evil estimation guided by the criteria of social and environmental tolerability, then, based on current results of reserve and risk comparisons, and taking into account at the same time the economical practicability aspects of the different ways of energy supply, the most urgent requirement turns out to be the immediate reduction of worldwide CO2 immission. This requirement which must be translated into immediate action is of priority. However, at present a significant CO2 reduction in connection with the securing of a sufficient worldwide energy supply can only be achieved by means of various consistent acions which are presented in this paper in the form of a set.
