Off the Press: Nuclear Energy Is a Fast and Inexpensive Way to Improve the World

Screen Shot 2017-12-10 at 15.25.47

This piece was originally published in the Finnish newspaper Aamulehti on Friday 8th of November 2017. The article is based on an earlier English blog piece I wrote, which was quite a bit longer than the 4500 character limit at the paper, and unlike it, included plenty of graphs and hyperlinked sources. For a long version of the topic you can head on over there. However, I felt I could hardly turn down a reader’s kind request to translate the newspaper-published piece as well. So here it is: the TL;DR version of my economical arguments around low-carbon electricity. A few graphs added.


We should produce more carbon-free energy in order to stop global warming, and avoid losing millions of lives to air pollution every year. But how? Despite the boom in renewable energy, carbon emissions in the world are on the rise. Concerning Finland’s largest source of carbon-free energy, the headlines in the media make for chilling reading: more delays and rising costs in the construction of nuclear power. Which is why I was astonished when I began digging up more exact numbers on the topic.

Despite delays, the construction costs of Olkiluoto 3 nuclear plant are comparatively small: when the plant comes into operation, its lifetime electricity generation is so tremendous, that the price of construction is at about a cent per kilowatt hour. The building costs of the next planned Hanhikivi plant is estimated to be similar per unit of energy. In Europe, construction costs of renewables, though drastically lowered, are still around four times as large at their cheapest. The price of building nuclear power, in other words, is only a threshold issue – not a long term argument against nuclear energy, but strongly in its favour.

How much do power plants cost-

For sources and calculations, see the original blog piece.

But nuclear energy has many other costs that should be taken into account: the lifecycle of nuclear fuel, plant upkeep and maintenance, and so forth. These type of comprehensive calculations put the price of nuclear power and renewables much closer to each other. In Finland and the US, nuclear is estimated to be the cheapest carbon-free alternative after onshore wind, whereas in France, UK, and South-Korea, it’s the the cheapest one all in all (a look at LCOE comparisons here). In the light of these figures, I can’t help but wonder about nuclear’s reputation as a particularly expensive energy form.

Mere price or even amount of electricity, on the other hand, does not translate directly to value for the consumer if availability is compromised. It is critical for hospitals, schools, public transport, private households and many other electricity consumers that electricity is available at any (or all the) time. Renewables like wind and solar are a good addition to clean energy generation up to the point when their intermittency becomes problematic. Electricity storage is still so tricky and expensive, that entire national battery capacities are counted in minutes. In this sense nuclear power is of a high value because it produces large amounts of energy at a reliable rate.

More about the many safety aspects of nuclear power, including a discussion about the ExternE project here.

Perhaps the most important measures are, after all, the total impacts that different energy forms have on the wellbeing of humans and nature – estimates of all external costs from mining, emissions, accidents, and other burdens over their entire life cycle. This nuanced question has been analysed among others by the EU-funded project ExternE, whose results resemble other similar comparisons: nuclear power is among the least harmful energy forms. Hydro, wind, geothermal, and nuclear energy save human lives and pose the smallest burdens on nature.

Climate scientist James Hansen, who has studied the net effects of nuclear power, estimates that existing nuclear power has so far save approximately two million human lives by replacing coal power and thus reducing air pollution.

People often fear nuclear power out of proportion – to such a degree, that at Fukushima, fear was a greater danger than radiation, which remained around the same levels as natural background radiation in Finland and caused no casualties at all.

Many still say that the risk of human error in the context of nuclear power is too great. I agree. Human errors in the assessment of the risks of nuclear power cost millions of lives every year – every time an opportunity to replace coal power with cleaner energy is wasted. Mitigation of climate change would be in much better shape if other countries would have followed France and Sweden’s lead back in the 70s and 80s.

How much do power plants cost- (1)The good news is that nuclear power is the fastest proven method of decarbonisation. Thirty years ago, France and Sweden reduced their emissions 3-4 times faster than what the best renewable booms have managed in the last decade.

The much delayed Olkiluoto 3 plant alone will be a 50 % larger addition of clean energy into the grid than what the record-holder on wind power, Denmark, has achieved at its fastest.

There are many ways to a better world, and all are needed. Nuclear energy is one of the highways.

    Don’t you mean that this is the non-TL,DR version? 😉 Or let’s start the JR,RC (Just Right, Read Completely) acronym.

    Totally correct about nuclear being the low-cost option. RoadmapToNowhere.com compares the cost of a national all-renewables grid with an all-nuclear grid. (It isn’t even close!)

    Call me an anti-wind bigot. I see NO EXCUSE at all for wind “turbines” They’re just inverted propellers. Their vices, ugliness, infrasound noise, bloody great rotating shadows, bird and bats slaughtered, are bad enough that I have a suspicion half of their support comes from a desire to discredits the existence of the problem they’re supposed to solve.
    On the other hand, the most obviously renewable energy technology is the class of reactors that turns common, non-fissile thorium into fissile uranium. It may be a mistake, or misguided shrinking from the anti-nuclear detestation of uranium, not to admit that the LFTR is actually dependent upon fission of uranium nuclei.
    One fission event, converting a uranium nucleus to fission products, releases energy and two or three neutrons. From a population of such events, comes new neutron per nucleus to create the replacement fissile nucleus, and another to perform the next fission.
    This, fellow liberals, is genuinely, obviously, renewable nuclear energy.
    There is nothing that a solar-source intermittent power provider can do, by replacing any of the power being provided by nuclear, to improve the environmental impact or cost of the power capacity being intermittently replaced.

    P.S. Maxwell’s Demon was a way to skirt around the laws of thermodynamics. Kelvin was primarily a thermodynamics expert.

    About “Fukushima” — the level of Human Error is high enough that there are people so deeply sunk in it as to imagine that the mere word suffices to destroy all argument for nuclear power at all. But it really isn’t even an argument for not living in Japan!
