“MHI and Veolia have worked in close collaboration on the design and build of the PCVI boom investigation system, with each organisation contributing its respective expertise.  
 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.
