Chapter 5

Supporting Structures


Chapter 5 describes the various types of steel and concrete structures that serve to support systems and equipment. We review their design basis and their multiple uses when the plant is in operation. We address the use of scaffold in nuclear power plants, as temporary or permanent installations, and the cautions that apply when the scaffold is permanent. This chapter also discusses the question of clearance between structures and commodities, a point of particular interest in the congested rooms and compartments of a nuclear power plant.
