Energy is a key item for sustainability. Most of the presently utilized energy is fossil fuels. They emit greenhouse gas and cause global warming. Renewable energies are free from this problem. However, they have other problems such as low density and an unstable power rate. Nuclear energy is a high density and stable energy without carbon-dioxide emissions. This issue of Sustainability focuses on nuclear energy as a sustainable energy. However, it has several difficult and inherent problems. The present light water cooled reactors can only use less than 1% of original natural uranium, and their resource problem is as severe as fossil fuels. But breeder reactors can utilize larger portions of natural uranium and thorium, and can be considered to produce energy for about a million years. Nuclear energy has a more difficult and inherent problem. It utilizes the same technology as used for making nuclear bombs. Therefore, we should consider physical protection, nonproliferation and other problems related to nuclear weapons. The nuclear energy production process produces radioactive materials at the same time. This makes nuclear reactor accidents very severe and leaves difficult waste problems even after finishing reactor operations. This special issue of Sustainability will show the potential of innovative nuclear reactor / energy system for sustainable energy by solving these problems at acceptable economic costs.
