Fusion Enterprises has been recognized by Energy Business Review Magazine as the exclusive recipient of “Top Nuclear Engineering and Manufacturing Services 2026,” based on our proprietary methodology, reflecting its position in the industry, and is also named among “Top Nuclear Energy Companies,” reflecting its broader leadership. This profile has been developed by the Energy Business Review research and editorial team based on insights from an interview with Mark Maybee, CEO and Founder.
Mark Maybee, CEO and FounderFusion Enterprises is responding to that need by bringing together established nuclear businesses and directing resources toward areas of growing industry demand. NWS Technologies, Master Machine and Container Products Company give Fusion a portfolio of unique capabilities purpose-built to support the existing nuclear fleet while contributing to the build-out of new infrastructure.
“We are combining the expertise and resources of our businesses to invest ahead of demand and build the capabilities the nuclear industry will need next,” says Mark Maybee, CEO and founder.
Solving Critical Challenges through Specialized Nuclear Expertise
NWS specializes in the maintenance, testing and regulatory certification of nuclear safety relief valves, helping existing plants maintain critical equipment and operate efficiently without downtime.
Through client partnerships and continuous improvement, NWS has helped extend valve service life from a single refueling outage to the regulatory maximum of three. For one customer, data-backed collaboration with regulators supported an extension to four cycles, reducing maintenance interventions while maintaining critical safety and performance.
Master Machine addresses aging infrastructure, component obsolescence, and new build initiatives through engineering, weld fabrication and advanced manufacturing. Its differentiator is a turnkey approach that brings design optimization, fabrication and manufacturing together, removing the need for customers to coordinate multiple specialized providers, accelerating mission-critical project timelines and mitigating delays.
By reverse engineering components that have been in service for decades and qualifying replacement parts through its robust nuclear quality processes, Master Machine helps operators address obsolete components when original manufacturers are no longer able to support them. Its capabilities extend across commercial nuclear, advanced reactors, naval applications, power generation, defense and nuclear-related medical applications.
Across these specialized operations, compliance is treated as a cultural foundation rather than just a regulatory requirement. Holding a 10CFR50 Appendix B, ASME Section III N, NPT with material, NS, NQA1 and other certifications, internal quality teams, independent third-party inspectors and customers provide layered oversight, creating a closed-loop system that verifies both workmanship and documentation.
Strengthening Expertise through Collaborations
Engineers, quality personnel and operations leaders collaborate across Fusion on problem-solving, hiring and continuous improvement, including cross-site Kaizen initiatives that bring fresh perspectives and specialized expertise to complex challenges. The model also allows one business to connect customers with expertise and solutions available elsewhere across the portfolio, broadening the resources available to solve sophisticated problems.
By bringing together nuclear businesses with decades of experience, Fusion combines deep industry knowledge, established capabilities and resources that would be difficult to replicate independently. This foundation allows Fusion to concentrate resources and investment on the areas where the industry’s needs are greatest, building capacity ahead of demand.
As the nuclear renaissance gains momentum, Fusion is aligning infrastructure expansion with those needs, working to have qualified facilities, experienced people and the necessary capabilities in place before capacity becomes a constraint.
For Fusion, strengthening nuclear infrastructure means supporting today’s fleet while building the industrial capacity that tomorrow’s nuclear growth will require.
