Not sure how you can categorically state that a Nuclear Power plant will operate for 100yrs of reliable energy when the world's oldest Nuclear Power plant has only been operating for 55 yrs.

Beznau nuclear power plant

Beznau nuclear power plant in Northern Switzerland takes the honour of being the oldest nuclear power currently in use.

Construction on the plant began in 1965 and Beznau 1 began producing power on 1 September 1969, with Beznau 2 following in 1972. It has two pressurised water reactors (PWR) built by Westinghouse with a capacity of 365MW each, for a total capacity of 730MW and able to produce 6000 gigawatt-hours (GWh) of energy. The plant is owned and operated by Swiss private company Axpo Holdings.

Accidents will happen

Despite its long run producing power, Beznau has been no stranger to accidents at its site. According to the Swiss Federal Nuclear Safety Inspectorate, there were 91 nuclear security incidents between 1995 and 2014.

However 86 of these were at level 0 on the International Nuclear Event Scale (INES), the least severe on its scale. Four were at level 1 and one in 2009 that was level 2, when two workers at the plant were exposed to “inadmissible” levels of radiation .

Following its reopening four incidents were recorded at in 2018.
