REI Automation has designed and built new-fuel assembly and material handling equipment.  REI has recently developed a fuel bundle assembly machine for BWRs.

REI Automation pioneered mechanical segmentation of large radioactive components beginning in 1999 by partnering with MOTA Corporation, now Siempelkamp Nuclear Services.  REI provided machine design and build services to create innovative machine tool designs that have become the standard in the nuclear decommissioning and dismantlement industry.  In 2013, REI Automation and Technical Concepts, LLC (TCEPS) have created a joint venture as REI Nuclear, LLC. REI Nuclear has created a team of nuclear industry experts to combine with the machine development expertise of REI Automation. REI Nuclear is the pioneer and most broadly-experienced mechanical segmentation company in the nuclear industry.
