Orano and TEPCO strengthen co-operation on fuel debris removal at Fukushima

This is a lot of nuclear baloney: former Areva now Orano’s unique experience in the dismantling of a nuclear power plant is at the Brennilis nuclear power plant, started in 1995 and still unfinished since then, Brennilis nuclear power plant having only one reactor and no meltdown whatsoever.

11 November 2022

Orano has signed an engineering support contract with Tokyo Electric Power Company (TEPCO) and its Fukushima Decontamination and Decommissioning Engineering Company subsidiary for the design of a high-activity facility for small scale retrieval of nuclear fuel debris from the Fukushima Daiichi NPP.

These debris consist mainly of a solidified mixture of molten nuclear fuel and other materials, located in facilities inside the reactor buildings. Orano engineers will be embedded directly within TEPCO’s organisation to provide technical support on the project to design High Active Cells for Small Scale Retrieval Planning and share Orano’s best practices in terms of engineering and operation.

Orano has unique experience in the design, operation and dismantling of reprocessing plants in France. This know-how will contribute to the enhancement of TEPCO’s in-house decommissioning and engineering capabilities which are necessary for stable and safe fuel debris retrieval operations.

Exchange visits to the Fukushima NPP and Orano’s La Hague site were organised to launch the contract. This will allow TEPCO to become familiar with the know-how developed by the teams from Orano at la Hague site in the retrieval of legacy waste.

France presents vitrification process for Fukushima

Same insane mentality that came up with NPPs and generating nuclear waste wsants vitrification which will melt long before the nuke waste becomes chemically stable. Amazing how self/other destructive some people are and what they’re willing to risk doing to other people and life forms:
23 October 2018
A project to demonstrate the use of innovative radioactive waste vitrification technology, developed in France, at the damaged Fukushima Daiichi nuclear power plant in Japan has been under way for the past six months.
In-can-vitrification-protoype-(CEA)
An in-can prototype developed at CEA Marcoule
Since 27 April, the French Alternative Energies and Atomic Energy Commission (CEA), Orano and ANADEC have been evaluating the potential of using the “in-can” vitrification process developed by CEA to treat waste from water treatment operations at Fukushima Daiichi. Such wastes from these operations include contaminated sludge and mineral adsorbents. Vitrification is the process for immobilising high-level radioactive waste in glass.
CEA’s Marcoule laboratory developed a compact in-can vitrification process in which the melting pot is disposable and serves as the primary canister for the solidified glass.
The project to demonstrate the use of the technology at Fukushima Daiichi comprises two main parts.
The first is to develop and study durable waste form conditioning matrix formulations. Tests on a laboratory-scale (100 grams), on a bench-scale (1 kilogram) and near-industrial scale (100kg) will be carried out in France at the CEA Marcoule laboratories.
The second part of the project is to conduct feasibility studies for process implementation, operation and maintenance principles and waste disposal. These studies will be led by Orano.
In a joint statement Orano and CEA said that laboratory-scale test and part of the bench-scale tests have already been “performed with success”. Near-industrial scale tests, they said, are under way. The feasibility studies will then be carried out, with the complete results expected to be delivered by the end of March 2019.
For the project, “technical and commercial interfaces” in Japan are being provided by ANADEC. This a joint venture set up in 2014 between Orano and Japanese nuclear power plant maintenance and radioactive material management company ATOX.
Multiple facilities including a multi-nuclide removal facility – the Advanced Liquid Processing System (ALPS) – are used to treat the contaminated water accumulated at Fukushima Daiichi plant. After the concentration of caesium and strontium contained in the contaminated water is reduced, the ALPS system eventually removes most of the radioactive materials except tritium. The treatment of all highly contaminated water which contained strontium, except residual water in the bottom of the storage tanks, was completed in May 2015. This has helped reduce the risks attributed to contaminated water, such as an increase in radiation dose on the premises or contaminated water leaking from the storage tanks. The water from which caesium and strontium have been already reduced will require additional treatment by ALPS for further risk reduction.
