What is the primary function of a containment structure in a nuclear facility?

The primary function of a containment structure in a nuclear facility is to prevent the release of radioactive materials into the environment. Containment structures are designed to withstand extreme conditions, including potential accidents, to ensure that any radioactive materials generated during nuclear processes remain securely within the facility. This is crucial for protecting both the public and the environment from the dangers posed by radiation.

Containment structures typically consist of multiple barriers made from robust materials that can withstand high pressure and temperature. They serve as the last line of defense in safety systems that manage radioactive substances, directly addressing the risks associated with radioactive leaks, spills, or emissions. By effectively sealing off potentially hazardous materials, these structures help maintain safe operational standards and facilitate emergency preparedness.

In comparison, enhancing energy output is not the primary purpose of a containment structure, nor is it designed for public access. While supporting structural integrity is important, it is more of a secondary consideration since the primary goal is to ensure safety by containing radioactive materials.
