Demand for seawater desalination is increasing, especially in developing countries where populations are growing at a high annual rate. If such demand is covered with fossil fuel energy, the influence on the environment, such as global warming, cannot be disregarded. Therefore, a small reusable PWR with mid-range pressure and temperature services and does not require on-site refueling has devised for seawater desalination. Distinct feature of this small PWR is that spent fuel is to be taken out with reactor vessel and refueled on the exterior fuel exchange base prepared independently. Thus the safeguards against nuclear proliferation increase at a plant site because lid of reactor vessel is never opened at the site, in principle. There has been a worldwide trend of the reverse osmosis (RO) method being adopted for seawater desalination. So we examined RO using the method of driving a high-pressure pump directly by low-pressure steam generated from this small PWR.
