Hmm. Wylfa - will I miss it? It's the largest employer on Anglesey, giving fairly good jobs to a shedload of people. Good jobs-for-life jobs. One thing to note is that it will continue to employ a good many people for a while yet, nuclear reactors don't shut down overnight, even if they're not producing any electricity. It used to power the local aluminum smelter, the largest single customer of electricity in the UK until it shut down in 2009.
We were very proud of it growing up in the bright-eyed technologically embracing 60s to 80s. Chernobyl cast a dark shadow on the industry in 86, especially in North Wales where the fallout meant that restrictions on highland sheep farming were only lifted in 2012 (yes, 2012, think on that those that think that Chernobyl wasn't that bad - 1500 miles away farmers were restricted for for 26 years).
I'm a nuclear believer, and there are plans for Wylfa B, a new nuclear generator, which I think is already a done deal. The inhabitants of Anglesey are divided over whether it would be a good thing (employment) or a Fukushima waiting to happen, but energy planning is not devolved to the people of Wales, so it's unlikely that local opposition will carry much weight in the decision. The biggest factor is how much subsidy the (UK) government will promise the French or Chinese investors for their nuclear megawatt-hour. Hinkley Point in England has been awarded £92.50, about 2x the current price of electricity guaranteed for 35 years, and the waste problem is owned (and paid for) by the government.
The fact that companies need shoveling crazy amounts of subsidy to build any reactors with the government picking up the bill for final waste management worries me that nuclear aint the glorious shizz that I was sold as a child in the 80s. On the other hand, if the UK government are hoofing megabucks somewhere, I'd rather it went to the incredibly beautiful but poor island of Anglesey than not.
