Want to fight climate change? Build more nuclear power

Nuclear energy has still some popularity in the US. Especially among technical people. But technology is only one thing. What are the effects on a society long term?<p>Here in Germany it is mostly dead. For us you are discussing positions of twenty years ago. The US has a very different energy situation compared to us: large country, nuclear weapons, lots of nuclear technology, extremely high energy use (more than twice than the average German), much lower population density, lots of energy sources, ...<p>Here in Germany we&#x27;ve seen a lot of the negative effects in a country with higher density in the middle of Europe:<p>* no plan or place for the waste<p>* nuclear power plants all over the country<p>* widespread corruption between politicians and industry<p>* protests were suppressed with military-like police, escalated almost into civil war<p>* lots of transport of nuclear materials through the country<p>* extremely costly research paid by the tax payer<p>* lots of promises of the nuclear industry just did not materialize: for example our pebble-bed reactor was closed silently, while earlier it was promised to solve a lot of technical problems<p>* centralization of electricity production in few monopoly-like companies with zero competition<p>The effects on an democratic society of nuclear technology is at least as bad as its technological problems. This was seen decades ago in the book &#x27;Der Atomstaat&#x27; and the effects had been shown in Japan, where the Atomstaat was more advanced than here in Germany. We were able to stop it.<p>Now we have to build-up renewable decentralized energy during the next decades. That&#x27;s the common goal here in Germany.

The obstacles that nuclear power faces are formidable.<p>One is that two other carbon-free options, solar and wind, are dropping in cost at a rapid rate at the same time that cost estimates for new nuclear plants are rising at a similarly rapid rate.<p>Another is that there isn&#x27;t anyone who thought their investment in the existing fleet of nuclear plants in the US was a good investment. They were uniformly bad investments, which is the primary reason for the 40 year gap with essentially no new plants ordered.<p>Furthermore, even completely amortized plants are shutting down in the US. They can&#x27;t even cover their operating costs, the few that shut down in the last year, let alone operating cost plus amortized construction cost.<p>So even with the federal government guaranteeing 90% of the funds used for new plant construction (free money) it hasn&#x27;t been easy to find investors willing to put up the remaining 10%.<p>Nuclear power is awesome, especially if it is fusion power, and the reactor is 90M miles away, and anyone can use it for free just by put an inexpensive fusion power receiving panel outside with a clear view of the sky.<p>One just needs to project what the wholesale price of PV power will be in 10 years to see the real reason it is difficult to find investors for new nuclear plants. Why spend $5B on a nuclear plant when you could spend it on five solar panel plants that each produce 1GW of solar panels, each year, creating substantially more jobs than the reactor would? Just asking.

Hopefully there are lots of people here who feel like I do, that building nuclear plants is a great idea -- just, what kind of nuclear plant should we build?<p>1. You want to use government funding to build nuclear plants. My response: please look at previous government-funded nuclear operations of all types. It appears this doesn&#x27;t work, from a failure to manage the environmental impact to a failure to keep the project cost-effective. This includes state-controlled energy companies, since nuclear power is a very tightly controlled business.<p>2. You want to use an unproven technology. My response: there are several well-proven nuclear options that are being developed by very promising companies. Please compare your technology with them. Some of the promising technologies are government-funded, however, which seems like a waste of a good idea.<p>3. You want to keep existing plants alive. This is nuanced. Some existing nuclear plants are necessary, but hopefully we can shut down the aging and dangerous and high-level-waste-producing ones in favor of cleaner alternatives. Doing so shouldn&#x27;t necessarily cost a lot of money.<p>4. You want to reprocess existing nuclear waste and burn it to low-grade waste while generating clean electricity. My response: if you can show that you&#x27;ve cleared the regulatory hurdles (a lot of waste is held by governments) and if you&#x27;re reasonably transparent about your progress, I&#x27;d like to give you a donation.

Why is France rarely mentioned in these discussions?<p>Most of their energy is nuclear. They&#x27;ve also standardized on plant design, which must have huge benefits - fungible employees and more MTBF being big ones.<p>All of our (the United States) plants afaik are bespoke designs, and can&#x27;t be cheaper than pumping out cookie cutters.<p>What are they doing right, and how do we copy it?

The people of the areas surrounding Fukushima and Chernobyl may beg to differ.<p>I&#x27;m not anti-nuclear, but the cost of a failure at a nuclear power plant is so high, that the engineering must be to similarly high standards. Unfortunately, as we have seen in the cases of 3-Mile Island, Chernobyl and Fukishima, this is not the case. We need to really figure that part out before opting for this route.<p>And then there&#x27;s the problem of nuclear waste disposal.

Important to note that nuclear accounts for only 90 deaths in history, while providing 17% of the world&#x27;s power.<p>source: <a href="http://www.forbes.com/sites/jamesconca/2012/06/10/energys-deathprint-a-price-always-paid/" rel="nofollow">http:&#x2F;&#x2F;www.forbes.com&#x2F;sites&#x2F;jamesconca&#x2F;2012&#x2F;06&#x2F;10&#x2F;energys-de...</a>

Note that we haven&#x27;t yet reached the end of the line as far as improvements to the manufacturing process of solar cells is conscerned, in particular <a href="http://www.nature.com/nature/journal/vaop/ncurrent/abs/nature13435.html" rel="nofollow">http:&#x2F;&#x2F;www.nature.com&#x2F;nature&#x2F;journal&#x2F;vaop&#x2F;ncurrent&#x2F;abs&#x2F;natur...</a> . Cheaper solar energy might not be far off.

The use of any sort of nuclear power with a well though out multi millenia waste storage system is irresponsible.<p>Ideally this would be accomanied by a secret cult of priests of the atom, charged with defending the sacred temple sites fovever. (Religion being the one institution proven able to survive millenia.)

As long as the nuclear waste problem isn&#x27;t solved, nuclear power can&#x27;t be the answer. Also the cost is very high, especially if you factor in risk&#x2F;insurance and decommissioning.

This is the easy way to get energia. Ok, We have seen that in Canada they use the dams, but we know that this harms the environment (for salmon). Here we really need to do research for alternative energy, do not think only about money and earnings, but think about the future. Otherwise we risk in 2050 to find the first deserts created by humans because of global warming.
