ASME Section III applies to which type of components?

• A. Residential plumbing systems
• B. Nuclear facility components
• C. Industrial refrigeration units
• D. Automotive fuel lines

Answer: (B)

ASME Section III governs nuclear facility components, focusing on safety-related parts of a nuclear power plant such as the reactor coolant system, containment, and associated supports. It sets the design, materials, fabrication, examination, testing, and quality assurance requirements to ensure these components maintain structural integrity under service conditions. That is why it applies to nuclear facility components. Other categories like residential plumbing, industrial refrigeration units, or automotive fuel lines are covered by different codes or sections (for example, plumbing codes for residential systems and other piping sections for non-nuclear equipment).
