This paper presents different time schedules for the construction of nuclear power plants in Poland., taking into account all tasks that must be carried out in connection with the preparation and realisation of the investment. In particular, the precise legislative procedure leading to the passing of the new Atomic Law is analysed, starting from research of foreign legislation through government actions and parliamentary works in both Houses, and ending with the presidential decision. Three scenarios of legislation process have been considered. The analysis presented shows that even in the case of very efficient and swiftly-passed legislation, construction of the first unit will not be finished quicker than in 15 years (i.e. in 2023). The road maps shown in the paper can be used in order to control the progress of works foreseen by the official governmental Work Schedule of the Nuclear Power Plant Programme in Poland, which was announced on 11 August 2009 [1]
