The nuclear waste issue reaches a decision in Sweden, after 50 years.

Today, 27th of January 2022, the Swedish government approved the KBS-3 method for depositing nuclear waste in Sweden. This is a decision that has been 50 years in the making, and that created and shaped the debate on Swedish nuclear power in the 1970s.

“We need power, but where to get it from?”

After World War II, Sweden was building itself up as an industrial welfare nation. For that, we needed a reliable and ample supply of energy. But where to get it?

Historically, Sweden had been dependent on hydropower from the mighty Norrland rivers…

…and imported oil.

However, it was clear that this could not continue. The resistance to further exploit the Norrland rivers was massive. This was the first major environmental issue in Sweden, where people took to the streets to protect the environment. Soon it became clear that any talk of damming up the 4 untouched rivers would be political suicide.

Meanwhile, it was becoming painfully clear that using oil for energy production was causing environmental havoc, with acidification of rivers and lakes, cancerous hydrocarbons released into the cities, carbon dioxide threatening the climate. Yes, already in the 1960s, there was awareness that carbon emissions was a danger to the climate.

So what were the options?

  • Renewables, in the shape of wind, solar, and geothermal power
  • Nuclear power

When the government put out the question as a public enquiry, the result was — as then Prime Minister Olof Palme expressed it — “completely unanimous”, in that renewables could not play any major part before 1990. That was too late.

By process of elimination, nuclear power remained.

And so it was, 12 reactors were approved by Palme’s Social Democratic party government. By the late 1960s there was complete political unity on the issue: Sweden was to adopt nuclear power, for security in power supply, for the environment, for the climate.

The hunt for a profile issue

This unity would not last though. The Swedish system of governing is a multi-party system, divided into partisan politics by way of a left and a right bloc. The left bloc was comprised of, the Social Democratic Party and the — then called — Left Party Communists. The right bloc was led by the Centre Party, and also included the liberal People’s Party, the Christian Democrats and the Moderates.

The Centre Party — an ideologically green party — was looking for a profile issue to challenge the left bloc on. They found that issue when Swedish Nobel Prize laureate Hannes Alfvén in 1972 expressed concerns over nuclear waste. Alfvén and Centre Party leader Thorbjörn Fälldin met, and from these meetings the Centre Party crystalized a standpoint on nuclear power…

Palme as the incumbent Prime Minister and Fälldin as the challenger, debated nuclear power fiercely. And the primary argument against nuclear power was the issue of waste. Fälldin — before the 1976 general election — famously said that he would not “compromise with [his] conscience” while referring to the waste, and vowed to stop all further expansion of nuclear power in Sweden.

And lo and behold, the profile issue actually struck a chord with the electorate. For the first time in decades, since before WWII, Sweden had a right bloc government. Fälldin got to work on abolishing nuclear power in Sweden

A failed promise

Two years later — in the autumn of 1978 — Fälldin’s government fell. The reason for this demands explaining a peculiarity of the Swedish Instrument of Government.

As with most democracies, Swedish official power is divided into multiple entities. But where most nations split power in three, Sweden does it in four. Where others combine Executive and Administrative power, Sweden puts a firewall between these two.

The upshot of this is that Administration — which is largely apolitical — cannot be bossed around by the political Executive; Swedish ministers are practically forbidden from making administrative decisions.

Granting permits for nuclear power is an administrative decision. So revoking or preventing permits to build and operate nuclear power is something that a minister cannot do. Instead, this is the subject for an apolitical administrative authority. And apolitical administrative authorities do not care if you as a politician have election promises to fulfill.

Thus, the Centre Party’s plan for halting the expansion of nuclear power was to introduce a law that demanded anyone wishing to obtain a permit for nuclear power activities in Sweden to show an adequate proposal for dealing with waste. Fälldin was convinced — by Alfvén — that this was an unsolvable task.

However, little did he know that in 1976, two SOUs (“State Official Reports”) had pointed to the remarkable find of natural nuclear reactors in Oklo, Gabon, Africa, and shown that a deep geological repository was not just feasible but also very likely to be adequate.

The nuclear power companies applying for permits with the Swedish Nuclear Power Inspectorate — the authority responsible for handing out nuclear power permits — referred to these reports, and other research papers from Gabon.

The Swedish Nuclear Power Inspectorate looked at this, and approved the permits.

Fälldin’s government suddenly had massive amounts of egg on their face. Feeling that they no longer had the vote of confidence by the Riksdag (Sweden’s unicameral parliament), the government resigned.

This was the beginning of the end of the — in this author’s opinion —only pragmatic argument against nuclear power.

A long and protracted end

As the reader is well aware, the 1970s and 80s were turbulent times for nuclear power.

The nuclear waste issue however, proceeded quietly. In 1984, a law was passed that established that the effort for creating a waste repository would be paid by the consumers. For many years, a levy on the electrical bill explicitly specified how much you as a consumer were paying to the Nuclear Waste Fund. This was counted at less than 1 öre per kWh (1 öre = 0.01 SEK, 1 SEK was valued at roughly 0.2 USD back then).

In close cooperation with first the Nuclear Power Inspectorate, later renamed to the Swedish Radiation Safety Authority (SSM), SKB, the company specifically created to engineer a solution for the waste, researched and designed what would later be presented as the KBS-3 solution.

In 2011, SKB submitted the proposal for approval.

SSM was the first toll gate. They asked for complementary research. SKB submitted that, and SSM passed the issue on.

Another toll gate was public approval. And in what seems a near bizarre twist to the story, the two counties proposed as sites for the repository, essentially fought each other over the issue, demanding to have the site located on their own grounds. Östhammar county won the battle, and was appointed as the site of the repository. Oskarhamns county got a “consolation prize” in the form of the encapsulation factory.

The third toll gate was the Land & Environment Court. They had little to say and swiftly approved the application.

Hence the application arrived at the final toll gate: the Swedish cabinet, and the desk of the Department for the Environment.

Just one small hitch there: the head of that department was a Green Party minister.

Quick rewind to 1978 again. The greens had just been humiliated on the issue of nuclear waste. Fälldin implored Palme to hold a referendum on the issue. Palme refused.

…until a pilot-operated relief valve jammed open in a brand-new unit at Three Mile Island.

Palme, seeing a nightmare of a summer leading up to the general election in September 1979, quickly agreed to the referendum, in order to remove the now politically radioactive issue from the table.

With the referendum, the greens again had high hope that the quick abolishment of nuclear power in Sweden would be achieved.

That did not happen. Instead, nuclear power was given a 30 year life-span in Sweden. The ideological greens were fuming at this, and quickly splintered out into a new party: the Environmental Party the Greens. First thing that went into the party programme was to declare nuclear power anathema.

Fast forward to 2021 again, and Green Party minister Per Bolund had on his table a paper to sign, a paper that — in effect — said that the Swedish government’s official position is that the nuclear power industry was right, and they did a great thing in solving the issue of waste, while the greens did nothing but fling dirt at them.

That paper remained unsigned for many months, and the political opposition began to accuse the government of stalling. Threats of constitutional hearings, even a vote of no confidence, were uttered.

The unexpected thaw

Then, suddenly, in late November 2021, the Green Party said “we are leaving the government”. The reason stated was domestic political issues, but the practical upshot of this was that a new minister for the environment was appointed, one that was not ideologically green.

The political opposition quickly swarmed the new minister — Annika Strandhäll — like disaster news on a nuclear event, and demanded a decision on the waste issue. Strandhäll delayed that decision over Yule 2021.

And — today — 27th of January 2022, the historical decision was announced…

KBS-3 is approved as a solution for high-level nuclear waste in Sweden.

50 years of waiting is over.

Why don’t nuclear reactors go kaboom? A reactor kinetics primer part – 3

Water Dolphin

We have discussed the time behavior of the neutron flux and reactivity feedbacks. Now it is time for the the thermal side of things. The point kinetics model describes how much energy is produced in the fuel, but we also need a model for how the energy is transported within the fuel, through the fuel cladding and into the coolant. To figure it out we need models for heat conduction through the fuel and cladding, heat transfer to the fluid through convection, properties of the fluid at different temperatures and pressures and so on. This blog post will deal with the heat conduction in the pellet and through the cladding.

Why don’t nuclear reactors go kaboom? A reactor kinetics primer part – 1

Nuclear reactors contain tons of fissile material and nuclear bombs contain only kilograms of fissile materials, so why does one of them explode with enough force to flatten a city but the other doesn’t? I will pull out some latex skillz and geek it out with equations to describe the physics behind whats in nuclear engineering is called reactivity excursions or RIA (Reactivity Insertion Accident). The level of these blog posts will be such that an interested and fairly math savy person can understand and calculate these kind of things on their own.

Nuclear news

Together they are giving a picture that Russia is really beginning to go all in for nuclear. Of course Russia has always been a pioneer in the nuclear field, but despite that they “only” have 33 reactors running producing less than 18% of electricity.

Why I do not trust “We don’t need nuclear” rethorics

Dear Mr./Ms. Anti-Nuclear Activist… for decades You have been telling me “It’s easy to get off nuclear, if we just want to!”. Well, alot more powerful people than You have made similar promises…

Where do we stand today after all these promises? Pretty much exactly where we were 5-10-20-40 years ago.

So – dear Mr./Ms. Anti-Nuclear Activist – You promise me gold and green forests… but You don’t deliver. Maybe this wasn’t Your fault. Maybe You’d like to blame Big Oil or lazy politicians or a public that just won’t see things the way You do. It’s allright… You can try to shift the blame any place You want. But it doesn’t matter whose fault it is, becasue assigning blame does not alleviate the problem.

So when You – dear Mr./Ms. Anti-Nuclear Activist – today, yet again, try to tell me it’s allright to renounce nuclear power, it means I cannot trust You, because things might no go they way You promise me they will.

What will You – dear Mr./Ms. Anti-Nuclear Activist – need to do to gain my trust again?

Well it’s easy: get the replacements up and running. Get full replacements for fossil fuels and nuclear power up and running, hooked to the grids and pumping GigaWatthours of energy into them, and I’ll trust You again.

So… dear Mr./Ms. Anti-Nuclear Activist…. get to work. We’re eagerly waiting for You.

Oh… and one last thing: while we wait for you to get this work done, You do not get to say we cannot make any new nuclear power if we want to, at least on the “We’re not gonna need it in a while”-argument alone.  Just saying this FYI…

German economy minister: “To prevent paper cuts, we must cut off our arms”

Ok, now it is official: Germany has gone batshit crazy.

Power firms should invest massively in coal and gas-fired power technology and renewable energy sources, Harry Voigtsberger, economy minister of Germany’s most populous state North Rhine Westphalia, said in the Financial Times Deutschland.

The original article can be read here (in german).

Angela Markel seems to be agreeing

In a document from Friday’s meeting obtained by Reuters, Merkel and her ministers laid out a six-point plan that includes a 5 billion-euro credit programme to support renewables.

It will also require building new gas and coal plants, Merkel said. “Gas and coal power plants were discussed… an accelerated exit from nuclear energy will lead to replacement power stations,” she said.

Why? So they can get rid of nuclear power…

This is about as stupid an idea as to say that in order to prevent paper cuts to your finger you should cut off your arms!

Sure… you achieve what you aimed for… but did you really concider the side effects before you took a knife and started carving?

Diese dummen Deutschen…

George Monbiot: “…the anti-nuclear lobby has misled us all”

George Monbiot, environmentalist and journalist… and once a strong opponent to nuclear power has faced an “unpalatable truth”: the anti-nuclear lobby lied to us.

http://www.guardian.co.uk/commentisfree/2011/apr/05/anti-nuclear-lobby-misled-world

The article is only about 30 years overdue… but I cannot stop smiling when I read this. Monbiot did what everyone should do: check the facts, think for yourself, dare to think you may have been either right or wrong.

The unpalatable truth is that the anti-nuclear lobby has misled us all

I’ve discovered that when the facts don’t suit them, the movement resorts to the follies of cover-up they usually denounce

George Monbiot

Over the last fortnight I’ve made a deeply troubling discovery. The anti-nuclear movement to which I once belonged has misled the world about the impacts of radiation on human health. The claims we have made are ungrounded in science, unsupportable when challenged, and wildly wrong. We have done other people, and ourselves, a terrible disservice.

Thank yo so much for this George. Along with Mark Lynas and Patrick Moore, you have shown that “green” does not have to mean “unscientific zeal”.
