摘要

Global warming problem is one of the most serious problems which human beings are currently face. Carbon Dioxide (CO_2) from power plants is considered one of the major causes of the global warming. In this study, CO_2 emission from Tokamak fusion power plants are compared with those from conventional present power generating technologies. Plasma parameters are calculated by a systems code couples the ITER physics, TF coil shape, and cost calculation. CO_2 emission from construction and operation is evaluated from summing up component volume times CO_2 emission intensities of the composing materials. The uncountable components on such as reactor building, balance of plants, etc., are scaled from the ITER referenced power reactor (ITER-like) by use of Generomak model. Two important findings are revealed. Most important finding is that CO_2 emissions from fusion reactors are less than that from PV, and less than double of that from fission reactor. The other findings are that (i) most CO_2 emissions from fusion reactors are from materials, (ii) CO_2 emissions from reactor construction becomes almost 60 % to 70 %, rest from reactor operation, and (iii) the RS reactor can reduce CO_2 emission half compared with the ITER-like reactor. In conclusion, tokamak fusion reactors are excellent because of their small CO_2 emission intensity, and they can be one of effective energy supply technologies to solve global warming.
