Where Never Reliable Wind & Solar Perpetually Fail, Ever Reliable Nuclear Power Just Works
Renewable energy rent seekers hate nuclear power for the same reasons we promote it: it works 24 x 365, whatever the weather and delivers power that people can afford.
Anyone claiming that carbon dioxide gas is destroying the planet and not promoting nuclear power simply can’t be taken seriously. Neither can anyone still suggesting that we’re only a few mega-batteries away from being powered entirely by sunshine and breezes.
Sure, places like Australia with abundant coal reserves will be using coal-fired power for generations to come. But that’s not a reason to reject a nuclear-powered future, out of hand. Especially in a country like Australia which holds the world’s largest uranium reserves and, despite its shifting policy of limiting the number of mines and states that have banned them, is the world’s third-largest uranium exporter.
That Australia, among the world’s largest uranium exporters, doesn’t rely on nuclear power astonishes those from the 30 countries where you’ll find nearly 450 nuclear reactors currently operating – including the French, Americans, Canadians, Japanese and Chinese. Another 15 countries are currently building 60 reactors among them. Nuclear power output accounts for over 11% of global electricity production. But not a lick of it in Australia.

An Upbeat Look at Nuclear with Rod Adams
16 December 2021
Robert Bryce’s Power Hungry podcast has an excellent interview with longtime nuclear energy blogger and podcaster Rod Adams. It’s almost two hours and has rather few views so I thought I’d post a little bit of background and highlights.
Rod Adams is a slightly gruff looking Annapolis graduate (a ring knocker as he calls himself) and former submarine nuclear officer. His voice sort of reminds me of the late great James Gandolfini. He’s certainly the world’s most prominent blogger and podcaster on nuclear energy. He cares very deeply about the importance of nuclear energy for human well being. His podcasts start with a catchy jingle, There’s a Better Way. He has an encyclopedic knowledge of the subject and his blog posts and podcast can get rather technical. Bryce does a great job of making this an accessible overview.
Lately, Michael Shellenberger has been getting a lot of attention promoting nuclear. He sort of gives the impression that too much attention is being paid to newer reactor designs and that large AP1000 type designs are the way to go, especially with Russia and China moving ahead. Shellenberger is admittedly not a STEM person, but he has educated himself and has a good overview of the basic concepts. Adams pretty much lives and breaths this stuff and follows the industry and new developments very closely. He’s excited about a new generation of driven people who see an opportunity to transform the future. BTW Adams has a great podcast interview with Shellenberger about his new book.
Adams is very optimistic about the potential of Nuscale’s upcoming small modular reactors. He’s very familiar with licensing and siting locations. Yes, they won’t be ready until 2027, but there are a lot of intriguing aspects. The biggest one is that they are designed to be meltdown proof. He has a recent post on economy of scale (republished from 1996) that has an interesting twist for light water reactors:
For example, one assumption explicitly stated in the economy of scale model is that the cost of auxiliary systems does not increase as rapidly as plant capacity. In at least one key area, that assumption is not true for nuclear plants.
Since the reactor core continues to produce heat after the plant is shutdown, and since a larger, more powerful core releases less of its heat to its immediate surroundings because of a smaller surface to volume ratio, it is more difficult to provide decay heat removal for higher capacity cores. It is also manifestly more difficult, time consuming and expensive to prove that the requirements for heat removal will be met under all postulated conditions without damaging the core. For emergency core cooling systems, overall costs, including regulatory burdens, seem to have increased more rapidly than plant capacity.
There are also a lot of intriguing prospects for siting. They will fit very nicely at existing coal plant sites. Coal plant sites are not likely to have gas pipelines and additional pipelines are being blocked. There should also be a lot more electricity demand coming with electric cars and gas heating being exchanged for heat pumps and such. One fascinating thing he points out is that nuclear costs have not actually gone up. It’s just that they have to deal with congested grid pricing from wind and solar.
One interesting new design is the Natrium from Terrapower and GE Hitachi. It will have a molten salt buffer between the core and the steam turbines. This will allow it to spool electricity generation up and down fast to deal with intermittent wind. Yes, nuclear power is so good it will enable the blight of wind turbines and stick us with them forever.
Adams sees a need for cutting CO2 emissions and says he thinks the best way to do it is with a carbon tax. He thinks this will help make prices more predictable and make planning easier for energy companies. He criticizes wind farm tax credits being the same for all locations, even where there’s already congestion. He credits Daniel Yergin’s book, The Prize, with showing how important it is to keep energy supply and demand balanced.
