Had someone try to tell me that gas supply was not an important determining factor of electricity prices in Germany, because it didn't account for a large enough share of generation. Apparently this person was crashingly unfamiliar with the notion that the cost of the last kWh generated, which always comes from the most expensive source, sets the price in a power-market system (by design, as these markets were a response to perceived inefficiency of rolled-in pricing).

It occurs to me that the Netherlands is a country reasonably well-suited, in terms of its pattern of settlement, to district-heating schemes. A great deal of that space-heating demand could be satisfied from combined-heat-and-power, thus economizing substantially on fuel. Which raises the question of why this has not been done.

As a person very susceptible to chill, I find that a few tens of watts of electric heat in the right place can help more than a much larger amount of space heating. Electric blanket, electric mattress-pad, I have a thing like an electric waistcoat that wraps around the torso, and even a kind of electric footwarmer. The main problem is that they all assume you will stay in one place!

If the electric torso-warmer had a long cord, and the outlets were near the ceiling…

This is actually a point that bears leaning on much harder.

People talk about solar and wind being cheaper and quicker to install than nuclear. This ignores the fact that, in traditional central–station power systems, transmission and distribution account for about 60% of the cost of delivering the kWh to the consumer, and generation 40%. Renewables require MUCH larger T&D investments, say 2—3×. Their effective fixed costs, and the cost of the kWh, are thus much higher.

On a generous estimate, you'd need 8 GW nameplate capacity of generation plus 96 GWh storage to serve a 1 GW load with reliability. Passing over the fact that NOBODY IN THE WORLD has 96 GWh of storage (the UK has about 30, for an average load of 72 GW), you'd have to inflate the costs of nuclear to Hell and gone before that would be cheaper than 1 GW of fission.

Unfortunately, wind and PV solar do not provide the same kind of energy services that thermal power stations do. To "fake it" is incredibly expensive and difficult (the largest proportion of grid storage in any major country is in Britain, and is equivalent to about half an hour of average consumption). So the real alternatives are fission and coal.

The harm done by coal is very real. The dangers of fission are mostly hypothetical.

In a word, simplicity. In any package-power situation, but especially in ship propulsion, you want the minimum of manpower and maintenance, the minimum of diferent parts and functions. Shipping would also prefer a minimum of risk, and PWR as the best-proven type would be ideal for them, except that it requires a lot of auxiliaries (water chemistry plant and so on), and steam plants of any kind require a lot of maintenance. Rod Adams, former US Navy, explains it better.

Solar and wind require several times the amount of T&D infrastructure that nuclear needs, especially when existing sites where the lines are already in place can be used.

According to reliable life-cycle analyses, nuclear needs about as much mining as solar and wind, or quite a bit less once we add a few "breeder" reactors into the system and close the fuel cycle. There is not strictly a need to mine any more uranium at all, as I have shown elsewhere.

As with the Machhu dam collapse in Gujarat a couple of years later, which is thought to have killed perhaps as many as 25 000 people, I tend to assign the River Ru catastrophe primarily to non-energy activities.

One of the first things neutron transmutation was used for was to convert gold into mercury.

Perhaps you're wondering why. The reason is that Au is monoisotopic (197), but natural Hg is not. The US Bureau of Standards wanted monoisotopic Hg for its sharp spectral lines. So in 1939 they shipped a quantity of the US Treasury's gold reserve to California, to be bombarded with neutrons from the big Berkeley cyclotron. Later it was sent to Oak Ridge, to the X-10 pile.

Ultimately, my attitude is shaped by the many times I have been told "we don't need nuclear, renewables are more than enough", and the fact that renewables have (at least since the 1970s) consistently been used as a smokescreen for anti-nuclear-ism, and consistently tied to the "low-energy society"/"degrowth" concept.

Not everybody who promotes renewables does so in bad faith, but renewables promotion itself is basically a bad-faith enterprise.

If you look at the long-run total cost of electricity to the consumer, which is the most obviously relevant criterion, you rapidly see that systems with a lot of nuclear typically rank near the bottom. Systems with a lot of solar and wind, which we are always told are "cheap and getting cheaper", generally rank near the top.

Nuclear is expensive when you only do a little bit of it.

Everything I've seen shows that, so far, typical lifetimes of offshore wind turbines are in the 10—12 year range. That should improve a bit once the experience is a bit better digested. We've seen foundation scour, a whole lot of stress-corrosion problems and just physical damage due to the sea-air interface, very rapid blade erosion due to spray, and of course the usual cyclic loading effects.

Nuclear plants belong near load centers, to supply heat plus power.

There's a very good reason why the very first power-producing fission reactor was a sodium-cooled fast breeder. It has been obvious from the first that the regenerative nuclear fuel cycle is necessary if fission is to meet a large portion of the energy needs of the world for a long time. But politicians continue to convince themselves, despite all available evidence, that fission will not be required for that, and promote converter reactors and direct disposal of spent fuel.

Certainly they believe that nuclear energy is radically immoral, "a fundamentally inappropriate exercise of human intelligence", regardless of what it does.

…than nuclear, which long ago proved to be cheaper than fossil-fuel power, at least in high-load-factor applications. Nuclear is often quoted as having a very high cost, but when you look at what you get for the money, the picture is quite different. This is especially important because most decarbonization schemes imply at least tripling electricity consumption in the wealthy countries, and much greater increases in the poorer ones.

…but saves considerably on heat pumps.

In a conventional central-station power system, with fuel-burning power plants close to the load, it's common for transmission and distribution to account for 60% of the cost of supplying the kilowatt-hour to the consumer. Renewables require far more T&D, even before we consider storage schemes. This implies that, even if renewables were completely free at the source, they would supply power at a higher price to the consumer…

In terms of the output of generic steam-plant components, it doesn't necessarily even mean tripling current output, especially assuming reactor types (such as HTR or the oil-cooled CANDU derivative) which can produce steam suitable for existing turbogenerators.
