「In the nuclear-related field, the company is jointly conducting experiments using a pre-pilot unit with 創イノベーション株式会社 and the Omura Laboratory of the Faculty of Science and Technology at Keio University, and is developing an implementation unit for use in the small-scale demonstration test outside the premises of a nuclear power plant, the next stage following Tokyo Electric Power Company's technology call for proposals.」

「As the feasibility study is expected to proceed, the company will continue working on the project as one of the 1 companies selected from 2 domestic candidates.」

「In the tritium removal field, the company is jointly developing a pre-pilot tritium separation technology implementation unit with 創イノベーション株式会社 and the Omura Laboratory of the Faculty of Science and Technology at Keio University. The unit is intended for use in a proposed demonstration test that clarifies the items to be examined in the feasibility study requested by Tokyo Electric Power Company following the secondary evaluation, including the applicant's technical capabilities and ability to achieve the required processing capacity, waste and other matters, operability, compliance with laws and regulations, and other items. It is also intended for use in the subsequent small-scale demonstration test outside the premises of the Fukushima Daiichi Nuclear Power Station.」

「In the tritium removal business, Tokyo Electric Power Company Holdings, Inc. notified the company in mid-March 2022 that its proposal had met the evaluation criteria in the secondary evaluation under the public call for proposals concerning tritium removal technology. The company has launched the feasibility study that follows the secondary evaluation.」

In addition to ALPS-treated water from the Fukushima plant, the company aims to separate and reuse tritium generated in large quantities at heavy-water reactors and other facilities worldwide.」

「In the tritium removal business, Tokyo Electric Power Company Holdings, Inc. notified the company in mid-March of the results of the secondary evaluation under its public call for proposals concerning tritium removal technology. The notification stated, "We have determined that the evaluation criteria have been met." In the process following the secondary evaluation, the company will proceed with a feasibility study and a small-scale demonstration test outside the premises of the Fukushima Daiichi Nuclear Power Station.」

「In the tritium removal business, Tokyo Electric Power Company Holdings, Inc. notified the company in mid-December of the results of the primary evaluation under its public call for proposals concerning tritium removal technology. The notification stated, "We have determined that the evaluation criteria have been met." The company is currently awaiting the results of the secondary evaluation.」

「In the tritium removal field, tritium separation and concentration demonstration testing was successful, bringing the technology to a stage where the company has confidence in its technical feasibility. On 27 May 2021, Tokyo Electric Power Company announced a public call for proposals concerning tritium removal technology, and the application process has now been completed.」

On 27 May 2021, Tokyo Electric Power Company announced a public call for proposals concerning tritium removal technology, and the company is currently preparing the documents for its application. At present, it has identified no issues that would obstruct compliance with the application requirements and expects to submit the documents by the deadline. The company aims to begin construction of the 1/100-scale pilot plant already under preparation, conduct repeated tests using actual ALPS-treated water, and complete a full-scale operating plant as soon as possible.」

「In the tritium removal business, the tritium separation and concentration demonstration testing that the company has been pursuing for some time was successful, bringing the technology to a stage where the company has confidence in its technical feasibility. Going forward, the company aims to begin construction of the 1/100-scale pilot plant already under preparation, conduct repeated tests using actual ALPS-treated water, and complete a full-scale operating plant as soon as possible. Testing with ALPS-treated water requires the cooperation of Tokyo Electric Power Company and relevant government authorities. Although the company has held repeated discussions with them to date, it will continue discussions with the relevant parties from every angle while communicating to the world that tritium can be separated.」
