Applied Technical Services offers nuclear NDT services to help design, system, and program engineers optimize inspections for their nuclear equipment. Our inspections address a wide variety of equipment, including raw water systems such as service water, cooling water, RHR service water, and emergency service water systems. ATS experts have the tools and knowledge necessary to perform all work with an outstanding level of quality.
We utilize a four-step Piping Condition Assessment cycle to provide inspection and failure analysis services for pipe, tank, and pressure vessel systems in the nuclear industry.
The Piping Condition Assessment Cycle
Strategic Inspection Planning
Equipment inspections are the last step in our nuclear programs. Our first objective is defining the client’s desired program outcomes and determining an effective plan that prioritizes their time and resources.
We use a probabilistic Degradation Model to help determine where the equipment is susceptible to program threats. The risk of failure is not uniform across an entire system; our models for corrosion and degradation rate and distribution allow us to pinpoint areas with greater risks and establish a more effective inspection plan.
Problem Mitigation
We can also set up efficient criteria for problem mitigation. ATS understands the wide variety of available problem mitigation options; we can help you easily design a decision tree to address continued operation, temporary or permanent repair, and replacement. Establishing precedents for mitigation before conducting inspections allows time for site organizations such as maintenance, welding, management, and operations to share their input.
Nondestructive Inspections
Our nuclear NDT inspection programs are results-based; we determine the most appropriate inspection to suit each client’s needs. We offer numerous inspection options, from guided wave testing to encoded phased array ultrasonic testing.
