Which ASME code is primarily concerned with the construction of nuclear power plant piping?

• A. ASME B31.3
• B. ASME B31.5
• C. ASME B31.1
• D. ASME B31.8

Answer: (C)

The ASME code that is primarily concerned with the construction of nuclear power plant piping is ASME B31.1. This code addresses the design, materials, construction, testing, and safety aspects of power piping, which includes systems found in nuclear power plants. ASME B31.1 covers both high-pressure and high-temperature piping intended for power generation, ensuring that the systems can withstand the challenging environments characteristic of nuclear energy applications.

The other choices, while relevant to specific piping applications, do not focus on nuclear power plants. ASME B31.3 pertains to process piping, which deals primarily with chemical and petroleum processes; ASME B31.5 is concerned with refrigerant piping; and ASME B31.8 addresses gas transmission and distribution piping. Each of these codes has its distinct applications and focuses on different industry needs, differentiating them from the specific requirements and regulations set forth in ASME B31.1 for nuclear power facility piping systems.
