Just so there will be no question in the dismal future, the electrical engineering community has pointed out quite clearly that this is a bad idea.

In a massive geomagnetic storm that could trigger a long-term power outage across large portions of the globe, the world's 400-some nuclear plants would be particularly vulnerable to catastrophic failure, for two reasons.

This is one of the most certain-to-happen of the various catastrophes that will occur within the next few decades. I'm not sure how to prioritize it compared to climate change, bird flu, massive socio-economic dislocation, etc., but this one is particularly frustrating because the technical experts say that the scenario WILL HAPPEN, and that there is a KNOWN WAY TO PREVENT IT, but there is no social support for doing anything about it.
