Surry Nuclear Reactors To Extend Lifespan To 80 Years (richmond.com)

QuantumPion writes: Dominion Virginia Power today will formally seek a second license extension for its Surry nuclear power plant, becoming the first utility in the U.S. to try to push the operating range for nuclear reactors to 80 years. If successful, the utility's pair of reactors in Surry County would be eligible to operate past 2050. The Surry plant, along with its North Anna sister site in Louisa County, were initially granted 40-year permits and operate today on 20-year renewals. Those two plants provide about 40 percent of Virginia's electricity.

However, they were made at already existing plants, IE adding another reactor to an already existing nuclear power plant, and worse, it's the old design - they finished up a reactor that had construction suspended back in the '80s.

Remember, we're only building 4 of them a year(at the 200 station level). That's $40bn/year. Or perhaps the 'valuation' of the existing infrastructure at that point. A better way to look at it is that maintaining our nuclear infrastructure at appropriate ages would be a steady $40-80bn/year. And if you're complaining about the cost to replace plants after 50 years, how do you justify spending on stuff that doesn't even last one?

Problem with that is capacity factor - which is around 30% for solar and wind, and around 90% for nuclear. 1GW of nuclear will produce as many MWh of electricity over a year as 3GW of wind and solar. Even if the price drops, eventually you'd need storage, which adds to the price.

      In any case, even 400 nuclear plants wouldn't provide 100% carbon dioxide free electricity generation. My 'ideal' carbon neutral mix is about 40% nuclear (replacing coal), 20% solar, 20% wind, and 20% other(hydro and everything else). The nuclear becomes baseload. Solar covers the average daytime demand increase. Wind, when widescale enough, tends to blow a touch more at night, so it helps compensate for solar. 'Other' includes much of your peaking capability outside of known daytime increases that can be handled by solar.

    First, it is restricted to soft ores. The *availability* of this method is not indicative of total supply. Uranium in hard ores still have to be refined with crushers before processing further.

    Acid leech mining is 'in-situ' - meaning the acid is pumped into the ground to dissolve rock. The risk you introduce with this method is polluting the water table. Any failure to assess the geology properly and it poisons aquifers. Some of these are used for farming so water is a pretty important commodity especially in dry continents where they mine uranium. I beleive this type of mining is illegal in the US for similar reasons.

    It's a similar externality to the coal industry releasing radionuclides in ash into the air, except into water table instead, as in both cases we are talking about a natural radio-isotope, i.e. before enrichment. So it may not be a worthwhile risk to take to get uranium that way.

    The liquid tailings produced have to be contained in acid dams. This liquid has a chemical and radiological toxicity of it's own and we have to store this by-product.

    Uranium mining already produces liquid acid effluents and I recall that one of these sites had a 2 megalitre acid tank, full of radioactive effluents, burst in a world heratige national park a few years ago.

    It may not be wise to trust water tables to these guys based on their existing record considering that ISL will create a lot more liquid tailings than the existing processes.

    However it neatly illustrates the core design issue of the once through cycle used in modern reactors. The front end industrial processes (mining) forces you to make this essential choice:

    1. you crush and process the ore and use a huge about of energy to get your fuel

    2. You spend less energy but take a really big risk

    These are the options the Nuclear industry has to consider to get it's fuel, it's no better than coal this way, just differently bad.

    Of course the third risk is if you run out of that available fuel you *have* to use hard ores which means you have committed yourself to a very low energy return for the remaining lifetime of your new AP1000 or EPR.

    This might also provide enough context to understand how the thorium fuel cycle creates a second similar problem with a different waste stream and, why the development of burner reactors was so important to end mining whilst transmuting existing transuranic stocks from the once through cycle.
