The global non-destructive testing for nuclear industry size was estimated at USD 573.36 million in 2025 and is projected to reach USD 1,120.37 million by 2033, growing at a CAGR of 8.9% from 2026 to 2033. Market growth is attributed to stringent safety regulations to ensure operational safety and prevent potential hazards, which is driving continuous demand for advanced inspection and testing services.
In addition, life-extension nuclear reactors are being operated beyond their original design life, resulting in increased emphasis on frequent and high-precision inspections to assess material integrity and prevent failures, thereby driving the growth of the non-destructive testing Industry in the nuclear industry.
The Industry growth is attributed to global expansion of nuclear power capacity coupled with the increasing adoption of advanced inspection technologies for enhanced safety. Automated and robotic NDT systems, digital radiography, and data analytics are increasingly used to improve inspection accuracy and improve efficiency.
These innovations enable faster and more reliable defect detection and help meet critical nuclear safety requirements. Moreover, rising energy demand and decarbonization goals globally is resulting in increasing construction of new nuclear plants in several countries for energy harvesting purpose. As nuclear infrastructure grows, demand for inspection services during construction and operation increases. This expanding pipeline of nuclear projects continues to drive global demand for NDT solutions.
Technological advancements in the Non-Destructive Testing (NDT) market for the nuclear industry are being driven by the integration of automation, robotics, and digital inspection technologies to improve safety and accuracy. Advanced techniques such as phased-array ultrasonic testing (PAUT), digital radiography, and remote visual inspection are widely adopted to detect defects with greater precision while minimizing human exposure to hazardous environments. For instance, in June 2025, Eddyfi Technologies, provider of non-destructive testing (NDT) inspection technologies, announced the commercial release of Cypher, a next-generation ultrasonic inspection platform integrating phased-array ultrasonic testing (PAUT) and the Total Focusing Method (TFM). The system was designed to deliver faster, high-resolution inspections with improved accuracy and real-time data capabilities, particularly for critical industries such as nuclear and power generation. In addition, the use of data analytics and AI-based inspection systems is enabling predictive maintenance and real-time monitoring of critical components.

Furthermore, expansion in non-destructive testing (NDT) within the nuclear industry is accelerating due to the growing need for improved safety assurance and the increasing complexity of inspection requirements in modern nuclear projects. Companies are increasingly expanding their capabilities to integrate advanced technologies, streamline expertise, and improve support for large-scale and technically demanding operations. For instance, in November 2025, SPIE Nucléaire, a subsidiary of SPIE, announced the consolidation of its NDT expertise under the new entity SPIE Horus. This integration brought together the capabilities of its subsidiaries (ABC, ETC and SIRAC) and marked a significant step in expanding its NDT expertise, while strengthening its ability to support complex nuclear projects more efficiently.
The regulatory landscape for non-destructive testing (NDT) in the nuclear industry is critical, as it ensures the structural integrity, safety, and reliability of nuclear facilities under highly stringent operating conditions. Organizations are continuously updating regulatory frameworks to incorporate advanced inspection technologies, strengthen safety requirements, and ensure uniform standards across nuclear operations. For instance, in July 2025, the American Society of Mechanical Engineers (ASME) released an updated edition of the Boiler and Pressure Vessel Code (BPVC), which became effective in January 2026. This update introduced improved requirements for non-destructive examination methods, including stricter qualification criteria, revised inspection procedures, and improved guidelines for in-service inspection of critical components. Such regulatory advancements are driving the adoption of more reliable and technology-driven NDT practices across the nuclear industry.
The non-destructive testing (NDT) for nuclear industry faces significant challenges, mainly high implementation costs and a shortage of skilled personnel. Advanced NDT technologies, such as phased-array ultrasonic testing, digital radiography, and robotic inspection systems, require substantial capital investment and ongoing maintenance and calibration. These expenses can be prohibitive, particularly for smaller operators or those with limited budgets. In addition, NDT in nuclear settings requires specialized training and strict certification, such as those set by the American Society of Mechanical Engineers (ASME). The shortage of qualified personnel can delay inspections and increase operational risks. These factors together limit the broader adoption and efficiency of NDT in the nuclear sector.
Some of the key companies in the non-destructive testing for nuclear industry include Mistras Group, SGS SA, Intertek Group plc, among others. Organizations are focusing on increasing customer base to gain a competitive edge in the industry. Therefore, key players are taking several strategic initiatives, such as mergers and acquisitions, and partnerships with other major companies.
