What Nuenergy, Inc. does

Nuenergy, Inc. is a U.S.-based, founder-owned nuclear engineering consulting firm established in 1993 by Michael Shlyamberg, P.E., and headquartered in Evansville with a Philadelphia-area contact presence. The firm delivers a portfolio of specialized professional services to nuclear power plant operators, nuclear regulatory bodies, and development banks, including Owner's Reviews and Independent Assessments, New Engineering Organization Development, Licensing Basis and Regulatory Assurance, Risk-Informed Safety Systems Functional Assessments (SSFA), and proprietary Calculation Review/Reconstitution. It also operates a recurring advanced engineering training practice — DLB Fundamentals & The Art of Design Review, The Art of Calculation, and Review of Safety Related Calculations — delivered to utilities and to the IAEA.

The firm's core technology is a set of proprietary methodologies — SSFA, Calculation Review/Reconstitution with its associated Calculations Desktop Guide, and the Vertical Slice Methodology — combined with deep cross-reactor expertise covering AP1000, APR-1400, ABWR, EPR, VVER-1200, BWR, PWR, CANDU, and RBMK. Its eight named principals each carry over 30 years of nuclear industry experience, with cumulative credentials exceeding 500 nuclear plant inspections and independent assessments performed for the NRC, DOE, IAEA, and operators. Notable engagements include Westinghouse AP1000 QA audits, NRC Engineering Design Verification inspections, Barakah NPP (UAE) new-build support for FANR, Embalse refurbishment technical advisory for CAF, and operating-plant work for Duke, Exelon, Entergy, TVA, Southern Nuclear, OPPD, and AEP.

The business model is quote-based, engagement-specific professional services revenue, with billable consulting projects (services) and course-fee training (products) as the two streams. The firm describes itself as a 'small business corporation' with 1-10 employees, no disclosed funding rounds, no institutional investors, and no M&A activity. Geographic reach spans North America, the Middle East, South America, and East Asia, primarily distributed through direct enterprise relationships and repeat engagements rather than channel partners.

Broad incumbents

• Westinghouse Electric Company: Original AP1000 reactor designer and global nuclear services provider. Nuenergy has served as a sub-tier consultant to Westinghouse on AP1000 QA audits, illustrating relative scale and the ecosystem position Nuenergy occupies as a specialist supporting the OEM.
• Framatome: Major international nuclear reactor vendor and integrated services provider offering engineering, fuel, and licensing support across the nuclear lifecycle. Overlaps with Nuenergy in licensing basis and engineering consulting, but is a much larger OEM with reactor design and fuel manufacturing operations.
• Bechtel Nuclear, Security & Environmental: Global EPC and nuclear project delivery firm providing engineering, construction, and licensing support for new build and operating plants. Comparable to Nuenergy in new-build engineering support, but at much larger scale with full EPC and construction capabilities.
• Curtiss-Wright Nuclear Division: Diversified industrial company with a significant nuclear engineering services division serving U.S. and international nuclear plants. Comparable to Nuenergy in regulatory and engineering support scope, but operates as part of a large public-company portfolio with broader hardware and software offerings.

Direct peers

• Jensen Hughes: Global engineering and consulting firm with a substantial nuclear safety, licensing, and risk-informed services practice. Directly comparable to Nuenergy in providing independent nuclear safety assessments, regulatory support, and engineering consulting to utilities and regulators, though at significantly larger scale.
• MPR Associates: Independent nuclear engineering consultancy offering design, licensing, and operational support to nuclear power plants and reactor designers. Highly comparable to Nuenergy given its similar nuclear-exclusive focus, mid-sized scale, and emphasis on independent engineering assessments for utilities and vendors.
• Structural Integrity Associates: Engineering consultancy providing structural, mechanical, and risk-informed inspection services to the nuclear power industry. Comparable to Nuenergy in serving nuclear operators with engineering assessments, code compliance, and life-extension support across operating reactor fleets.
• Enercon Services: Engineering, environmental, and nuclear services firm offering independent oversight, design verification, and engineering support to nuclear power plants. Comparable to Nuenergy in the niche of nuclear engineering consulting and independent third-party assessments for utilities and regulators.

Regional players

• Studsvik Nuclear Consulting: Sweden-based nuclear engineering and consulting firm providing fuel, decommissioning, and engineering services across the European nuclear fleet. Comparable to Nuenergy in the type of specialized nuclear engineering services, though primarily serving European rather than North American operators.

Emerging players

• Holtec International: Nuclear technology and consulting company expanding into SMR development, used fuel storage, and decommissioning services. Adjacent peer with overlapping nuclear consulting and engineering capabilities, though differentiated by a primary focus on hardware and facility deployment.
