Evaluation of the trial studies for a advanced marine reactor, (8)

JAERI carried out the trial design of three type reactors (semi-integrated type, integrated type, and self pressurized integrated type) in order to clarity reactor type of advanced marine reactor for the best practical use in future and to extract its research and development theme. This report presents the comparison and estimation of these three type reactors from economical view point. Economical comparison carried out with next items for estimating the operating cost of ships powered by these three type reactors. (1) cost of reactor plants. (2) cost of fuel processing. (3) fuel cycle cost. As a result, it is cleared that the operating cost is the lowest in the ship powered by the integrated type reactor. (author)
