Chapter 21 - Underground location of nuclear power plants

Abstract

This chapter focuses on underground location of nuclear power plants. Plants can be built at ground level with external surfaces of the vital parts. These vital parts are covered with soil or special material. Plants can also be located in deep excavation. The location of the turbine–generator system at depth is close to the reactor cavern. Various feasibility studies have been made in recent times in Sweden, Germany, and Switzerland. The consequences of possible severe accidents can provide better mitigation. The underground location has been the most effective solution, even against extreme attacks. A sub-surface location can be implemented in a unique way to resist any conventional weapon and nuclear bombs. The increase in cost is also significant and many evaluations have been made. The increase in cost is also because of the increase in the construction time. High cost and long construction times can be weighed against the potential benefit objective of improving the resistance against severe accidents.
