Development of a CO₂ Free Nuclear Total Energy Supply System

Abstract

Nuclear power plants have a number of advantages in that "nuclear power plants are environmentally acceptable" as they do not produce carbon dioxide, and fuel loaded in a reactor core has a stockpiling effect to be advantageous in terms of Japan's energy security. This system is based on a small PWR of 30MWth thermal output. It's maximum electrical output is 10MWe. This system aims to supply all energy for life, for example, heat, electricity and hydrogen for fuel cell car, for 2000 to 3000 houses. This system assumed to be built on high latitude like Hokkaido. To confirm the simulation result, the heat transport experiment was carried out. In small size hot water pipeline using metal pipe with polyurethane thermal layer, the feed-water temperature and return-water temperature were measured. As a result, the water temperature was kept high enough, and this thermal calculation method was applied for actual size pipeline. The result of heat loss calculation was about 1 °C / 5km.
