Since 2016, Veolia has worked in partnership with Mitsubishi Heavy Industries (MHI) to support clean-up activities at the Fukushima Daiichi Nuclear Power Station. Both organisations share a common objective: advancing the Fukushima Daiichi decommissioning programme safely and effectively.
Key Facts
Partnership established in 2016
PCVI boom investigation system designed and built by Veolia
Supports fuel debris retrieval from Unit 2
Active deployment-phase support at Fukushima Daiichi
Ongoing multidisciplinary engineering engagement
As the programme transitions from testing to deployment, Veolia’s continued involvement supports deployment planning, site readiness, and operational preparation. Through this collaborative approach, both teams remain aligned on the safe and steady progress of the Fukushima Daiichi decommissioning programme.”
As the programme progresses from testing into deployment at Fukushima Daiichi (1F), Veolia continues to support MHI through:
Deployment planning
Site readiness activities
On-site technical monitoring
Advisory support
From Design to Deployment: The PCVI Boom Investigation System
Veolia’s nuclear solutions business led the design and build of the Primary Containment Vessel Investigation (PCVI) boom investigation system, supporting the programme’s goal of fuel debris retrieval from Unit 2.
This transition marks an important step from system validation to live operational implementation within a highly complex nuclear environment.
Multidisciplinary teams from Veolia remain engaged at Fukushima Daiichi to support operations of the PCVI system, including:
Boom deployment
DexterTM haptic feedback robot manipulator tasks
Ongoing operational alignment with MHI teams
Advisory support
Site Readiness and Operational Preparation
As part of these preparations, in February 2026 Veolia hosted colleagues from MHI and Marubeni Utility Services (MUS) at its Nuclear Solutions headquarters in Abingdon, UK. These sessions supported site-readiness activities and ensured that specialist engineers are fully prepared to provide deployment support at the 1F site.
Multidisciplinary teams from Veolia, spanning mechanical, electrical, control and software engineering, remain engaged at Fukushima Daiichi to support operations of the PCVI system.
This collaboration demonstrates how Veolia and MHI work together through clearly defined roles and shared objectives, combining design expertise, operational support, and a common commitment to the safe and successful delivery of the Fukushima Daiichi decommissioning mission.
The safe decommissioning of Fukushima Daiichi remains one of the most technically complex nuclear programmes in the world. Through sustained collaboration with Mitsubishi Heavy Industries, Veolia continues to contribute specialist engineering capability that supports the safe and effective progression of this mission.
