In the USA, waste is stored outdoors almost everywhere in the country. With sufficient protective thickness, no external radiation, so cancers ...

I dream or are they bits of reactor hearts not even vitrified?

As for the follow-up of possible leaks, it is better to leave them in the open air than to flee them 400m deep!

But in France we have less space and especially less desert than in the USA ...

Before reaching this point, fuel assemblies spent many years in a pool for radioactive decay.

vitrification is also only a pleasant joke because we have NO retreat over thousands of years to know if it will be effective or not in time, the time of its irradiation released without possible control. But the technocracy will claim that in the future we will find the solution to the current problems ... as usual!

it is the strategy of shit that we shit and that we leave in the open air, it stinks, or that we bury so as not to step on it. Except that shit, it does not stay thousands of years on the arms!

Sweden to expand Forsmark's low- and intermediate-level nuclear waste underground storage center.

Environmental court approves Swedish repository expansion

14 November 2019

The expansion of Sweden's existing SFR repository for low and intermediate-level waste at Forsmark has been approved by the Land and Environment Court in Stockholm. With approval already granted by the nuclear regulator, the government will now make a final decision on the application.

Drilling of the first lateral gallery for long - term spent fuel storage begins in Onkalo, Finland.

Work starts on first disposal tunnel at Finnish repository

07 May 2021

Excavation of the first final disposal tunnel has started at the Onkalo underground used nuclear fuel repository near Olkiluoto, Finnish radioactive waste management company Posiva Oy announced today. The repository - the first in the world for used fuel - is expected to begin operations in the mid-2020s.

Used nuclear fuel will be placed in the bedrock, at a depth of about 450 meters. The disposal system consists of a tightly sealed iron-copper canister, a bentonite buffer enclosing the canister, a tunnel backfilling material made of swellable clay, the seal structures of the tunnels and premises, and the enclosing rock.

The first five tunnels to be excavated during the next 18 months mark the beginning of an extensive building effort, Posiva said. It is estimated that 100 deposition tunnels will be excavated during the 100-year operational period of the final disposal facility, and will have a total length of about 35 kilometers. The maximum length of each tunnel will be 350m. The tunnels will be about 4.5m high and about 3.5m wide.

The excavation of the first five tunnels is part of Posiva's approximately EUR500 million (USD607 million) EKA project that covers all the final disposal facilities needed, including both their construction and equipment, as well as the start of the final disposal operation in the first deposition tunnel.

The company said the start of the excavation is a "significant milestone" for Posiva, as it comes after years of development activities on research and methodology for rock construction. It noted that Finland's Radiation and Nuclear Safety Authority (STUK) verified before the excavation began that the pre-conditions specified for starting the work had been fulfilled.

"The years of research and development of rock construction that have produced procedures for the construction of a nuclear facility suited to the Finnish bedrock have culminated in this moment," said Posiva Construction Manager Juha Riihimäki, adding that the development of the methodology started with the construction of the Onkalo facility in 2004.

Encapsulated fuel

Posiva's plan is for used fuel to be packed inside copper-steel canisters at an above-ground encapsulation plant, construction of which began in September 2019 and is scheduled to be completed in mid-2022.

About 30 canisters will be placed in each tunnel, Riihimäki said. This number depends on how many deposition holes there are in the tunnel, which is determined by the volume of suitable rock based on the rock fractures. The 30 canisters placed in each tunnel can accommodate a total of about 65 tons of used nuclear fuel.

Looking for German nuclear waste storage sites in France, is it perhaps very smart ?. But we are starting to get used to your pro-nuclear ideological content.

On the other hand, if you go to Greenpeace Germany, you will find the map of the country (I have translated for you) the same elsewhere.

Where is highly radioactive waste stored? How many waste containers
are located in the respective interim storage facilities? Where are
German nuclear power plants and how long will they remain in service?

Should France deprive itself of nuclear electricity because there would be no solution for waste?

Since its origin, the French nuclear industry has taken meticulous care to manage the radioactive waste produced. In particular, it took the decision to assume its responsibilities as a nuclear operator by reprocessing spent fuel in order to recover both the reprocessed uranium and the plutonium which are nuclear fuel (nuclear materials) and thus reduce waste from Long-Lived High Activity (HA-VL) only to fission products and assembly skeletons. The process of managing radioactive waste and all of the disposal facilities ensures that the waste is confined for a sufficiently long time, depending on its characteristics, so that it cannot present any risks for current and, above all, future generations.

After more than 50 years of operation of nuclear power in France, more than 2100 years of operation of pressurized water reactors and a saving of 6,1 billion tonnes of CO2 compared to gas combined cycles, waste such as The operation of the power stations has caused no impact either to the environment or to man. Few industries are capable of posting such a balance sheet.

In conclusion, we must affirm that there are no problems with radioactive waste. All have a suitable and lasting solution.
