Small, Modular Nuclear Reactors — the Future of Energy?
cylonlover writes "This year is a historic one for nuclear power, with the first reactors winning U.S. government approval for construction since 1978. Some have seen the green lighting of two Westinghouse AP1000 reactors to be built in Georgia as the start of a revival of nuclear power in the West, but this may be a false dawn because of the problems besetting conventional reactors. It may be that when a new boom in nuclear power comes, it won't be led by giant gigawatt installations, but by batteries of small modular reactors (SMRs) with very different principles from those of previous generations. However, while it's a technology of great diversity and potential, many obstacles stand in its path. This article takes an in-depth look at the many forms of SMRs, their advantages, and the challenges they must overcome."
I think you are ignoring the distribution costs, which are not trivial. The distribution fee is a significant part of my utility bill. It means that Solar or a small wind turbine doesn't have to be compeditive with the efficiency and cost of retail electricity at all. It could be miserably inefficient actually. But if the generation cost is cheaper than the utility's generation+distribution fees, then it may be financially viable.
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.
Something which doesn't often get discussed, but which I learned about a couple years ago - a number of knowledgeable people have said that what really killed nuclear power in the United States was the Shoreham Power Plant.
This was a nuclear power plant built in Long Island, New York, for about $6 Bn. The plant passed certifications and inspections and was all ready to go into commercial operation. However, because of politics, the plant was never able to get the go ahead from the State of New York to operate. The governor, Mario Kuomo, basically vetoed an *already built* power plant.
As long as the laws are such that investors can't get reasonable assurance *before* they spend all the money to build the plant, that they will be definitely allowed to operate as long as the plant meets relevant technical standards, the *politics* of the situation make the plants not viable.
Without such political uncertainty, nuclear plants are, generally, good investements, economically. A nuclear plant (depending on how much power it produces), should produce more than enough power to pay for itself in the course of 60 years, if it's allowed to operate.
