Bullocks.

1. In areas and times of extreme climate, nuclear power plants are regularly shut down because of the dangers they pose. In France the heat waves of 2003 and 2006 saw shut downs of the reactors (because of a low flow of water in the rivers for cooling) - just at a time when more energy was needed to make living spaces livable for people sensitive (elderly folks) to high heat. We're headed towards more volatile climates.

2. Nuclear reactors are regularly kept running way beyond their "best by" date, increasing the threats those reactors pose to their environments - and particularly human life.

3. Nuclear power relies on a steady stream of uranium being available for mining. The process of uranium mining is extractive and environmentally destructive. Sure, the power plant is clean, but what it needs to run isn't. Additionally, the US only mines 3% of the world's uranium.

Nuclear isn't the panacea the nuclear industry would want you to think it is.
