Sweden is perhaps the “greenest” country on earth. Their electric supply is a healthy mix of hydropower, wind, solar and biomass to make things go when the sun doesn’t shine and the wind doesn’t blow. Many cities are well planned where nearly all residential heat comes from spillheat from power plants. In Linköping the year 1967 the whole town was heated with surplus electricity during the spring flood. No house was allowed to have a fireplace in the regulated zone (except the city Architect’s and 3 other townhouses that somehow escaped the ordinance.) The energy use looks like this for Sweden:

Sweden once supplied nearly 40% of its energy needs via nuclear (electricity and heat) About half of the nuclear installations are retired and the last 6 are to be decommissioned before the end of the decade. To end nuclear energy was decided by a previous government in 1980 and the phase-out was to be completed in the mid 2020s. The goal was to generate 100% electric energy from renewable sources by 2040. (later changed to 2045).

Then Sweden had an election in 2022 and the Social Democrat, Green and Socialist coalition got replaced with a moderate, Christian Democrat and Liberal coalition with support of the nationalistic Sweden Democrat party. On June 20 they changed the slogan to 100% fossil-free electric energy by 2045.

This goal is impossible to meet without expanding nuclear power, especially since Sweden has specified that all new cars must be electric by 2035.

Then in January 2023 Sweden announced the largest Rare earth metals find in Europe. Europe is right now importing 98% of its rare earth metals from China. The find is called the Per Geijer deposit right next to the World’s largest underground Iron ore mine, the LKAB Kiruna mine located 120 miles north of the polar circle.

The new find is still basically a magnetite and hematite ore of excellent quality that also contains a significant amount of P2O5, which is premium fertilizer feed-stock. In addition It contains the largest find of rare earth metals in Europe. So far it is proven to contain the following Rare earth Metals:

Heavy Rare Earth Oxides (HREO) include: Eu₂O₃, Gd₂O₃, Tb₂O₃, Dy₂O₃, Ho₂O₃, Er₂O₃, Tm₂O₃, Yb₂O₃, Lu₂O₃, Y₂O₃.

Light Rare Earth Oxides (LREO) include: La₂O₃, Ce₂O₃, Pr₂O₃, Nd₂O₃, Sm₂O₃.

HREO constitutes 17% within the tested apatite concentrate samples and 19% in the overall exploration samples.

LREO constitutes 83% within the tested apatite concentrate samples and 81% in the overall exploration samples.

Just take a look at all the uses for rare earth metals. The most sought after pays all the cost of mining and refining, and the rest are readily available at nominal cost.

What is not mentioned is the content of Thorium and Uranium, but Thorium is always found in small amounts where ever Rare earths are found and very often some Uranium is also found in the ore.

In order to meet the need for both extraction of raw materials and at the same time increase Europe’s processing capacity LKAB has recently become the main owner of and entered into a cooperation with Norwegian REEtec.   They have developed an innovative and sustainable technology for the separation of rare earth elements that can compete with the dominant Chinese production. The planned extraction site is proposed to be in the Luleå area.

Rare earth ore nearly always contains measurable amounts of Thorium and/or Uranium.The Thorium is nearly always returned to the slag heap, and sometimes the Uranium too if the concentration is low. No information has been given yet how much of anything the ore contains, but it is safe to assume that it is the largest ore find in Europe.

Sweden has a long history of mining. Before 1288 A.D. the local farmers of Falun found copper in what was called Kopparberget and the first documentary evidence of the mine appears in a letter from 1288 giving the Bishop of Västerås a one-eighth share in the mine in exchange for landholdings. The document shows that a cooperative organization by this time was managing the mine, with shares being bought and sold. The mine grew, and was once the largest copper mine in the world. This is also the reason the traditional color of Swedish farms is red, thanks to subsidies from the government if they painted their gray wooden farms and barns with Falu red paint.

Later Sweden became the producer of the best ball bearings in the world, and produced specialty steel for a variety of uses, such as the Sandviken Stradivarius musical saw.

For a while the mines in Sweden were many, but through environmental regulation and cost consideration Sweden now has only 12 mines left in operation. Many of the discontinued mines were started before there was any real environmental regulations, so the cleanup of abandoned mines is still ongoing. Sweden has no coal mines and no natural gas fields.

Sweden is the world leader in recycling everything that is economically defensible to recycle, and the rest of the waste products are, if possible incinerated, producing heat and some electricity. Very little, about one percent is returned to landfills. However, incineration is not recycling, Sweden is burning their only source of coal.

What I am proposing is somewhat akin to the old charcoal kiln; but instead of using wood, the source is trash sonverting trash to coal and gasses.

This is an opportunity for Sweden to be the world leader in recycling nearly everything, including CO2. It just takes energy.

This is my proposal:

Build small modular molten salt thorium reactors, U233 or U 233 and and Plutonium two fuel reactors, an inner shell of U233 or Plutonium as fissile source, and an outer blanket of Thorium, which is the fertile source to generate more U 233 than is consumed. It can be gas cooled, using Helium or molten lead, both work well. Power output will be 100 to 200 MW, and the output temperature will be around 600C.

Municipal, industrial and construction waste will in the first stage be dried, removing nearly all water from the trash. The trash will then be fed into an outgasser, which is fed by 600 C Nitrogen generated from the nuclear heat source, preventing combustion. This will act as a charcoal kiln leaving high quality charcoal to be separately treated and refined, separating out metals and other contaminants. The gasses will run through a turbine generating electricity and scrubbed, separating the hydrogen, carbon, oxygen, chlorine and whatever was in the gasses.

By reducing waste to coal, graphite, graphene and separate hydrogen, oxygen, other gasses and metals it will be true recycling rather than a common waste to power and heat incinerator that produces CO2 and water from H2 and O2, truly wasting energy.

What will Sweden do instead?

SMRs. In Sweden, Kärnfull Next, a subsidiary of Kärnfull Future AB, became the first company in Scandinavia in March 2022 to develop SMR (Small Modular Reactors) projects. Kärnfull Next will work together with GE Hitachi (GEH) towards the deployment of the GEH’s BWRX-300 SMR. A memorandum of understanding was signed between the two companies for this purpose. A letter of intent was also signed with the Finnish utility Fortum at the end of 2022 to explore opportunities for SMR development in Sweden.

In February 2021, the Swedish subsidiary of the energy company Uniper signed an agreement with the developer of the LeadCold SMR and the Royal Institute of Technology (KTH) with the aim of building a demonstration plant at the Oskarshamn site by 2030. It is envisaged that the LeadCold SEALER SMR will generate between 3 to 10 MW over a period of 10 to 30 years without the need for refueling.

In June 2020, Vattenfall announced that it was conducting a pilot study to examine the construction of at least two SMRs adjacent to the Ringhals nuclear power plant. If the outcome is positive, the first SMR in Sweden could be commissioned in the early 2030s to replace the Ringhals 1 and 2 units, which have been shut down.
In December 2022, the French utility EdF and the Finnish company Fortum signed a framework cooperation agreement to jointly explore opportunities for collaboration on the use of SMRs and large nuclear reactors.
