The analysis can compare the component's intended function and design basis with operating conditions, test results, instrumentation, maintenance records, inspections, calculations, and the sequence of events under dispute. Depending on the system, relevant engineering questions may involve pressure, temperature, flow, heat removal, structural loads, electrical supply, control functions, or interactions with other equipment. NRC reactor reviews treat nuclear plants as interconnected structures, systems, and components and separately examine reactor systems, coolant systems, engineered safety features, instrumentation and controls, electric power, and other supporting systems.
A Nuclear Engineering Expert Witness may examine drawings, specifications, material records, procurement documentation, manufacturing information, inspections, test results, installation history, maintenance, and the component's intended function. The importance of a particular characteristic depends on the component and how it is used in the nuclear facility. For certain commercial-grade items intended for use as nuclear basic components, NRC describes a dedication process that identifies critical characteristics and verifies their acceptability through inspections, tests, or analyses. For activities affecting the safety-related functions of covered structures, systems, and components, NRC quality-assurance requirements also address procedures, recordkeeping, inspections, corrective actions, and audits.
Engineering questions may involve waste collection, processing, handling, storage, shielding, containment, equipment performance, or interfaces with plant systems. The technical analysis depends heavily on the type and characteristics of the radioactive material involved. NRC distinguishes several radioactive-waste categories. Low-level waste can include contaminated clothing, tools, filters, treatment residues, and equipment, while high-level waste includes spent reactor fuel when accepted for disposal and certain wastes from spent-fuel reprocessing. An engineering expert can evaluate the technical system and records without substituting for counsel or the regulatory authority on the ultimate legal classification or compliance determination.
Nuclear structures and components can experience degradation through mechanisms that depend on material, environment, temperature, radiation, stress, loading cycles, and operating history. An expert may compare inspections and measurements over time, review maintenance and repair history, and assess whether an identified degradation mechanism is technically consistent with the observed condition. NRC's materials-degradation research addresses aging in reactor pressure vessels, core internals, piping, electrical cables, concrete, and other structures and components. NRC license-renewal reviews likewise focus in part on managing aging effects in passive, long-lived structures and components.
