For that reason,this is an important research issue when considering the future fusion energy power plant.
In the future fusion reactor, hydrogen isotope fuel will cause a fusion reaction and become helium.
To the extent that the amount of leakage is small,we can reduce the size of the future fusion power generation plant.
In future fusion plasma, too, it will be extremely important to improve the magnetic island's confinement state.
Through this research we aim to establish methods for producinggentle detached plasmas appropriate for the divertor in the future fusion reactor.
In the future fusion reactor, all elements will be impurities, with the exception of deuterium and tritium as the fuels.
Here we will introduce integrated simulation research that is important inaccurately predicting plasma performance in designs for the future fusion energy power plant.
This indicates that in the future fusion power generation plant there will be a sufficiently small degree of losses.
This is approximately equal to the heat load on the inner wall of a space rocket engine's skirt(theplace where fire is blown), and in the future fusion reactor the divertor will be exposed to this amount of heat continuously through the year.
In the future fusion power plant it will be necessary for the ions and the electrons in the plasma to be at the same temperature.
In the future, by comparing experimental data that we have obtained and theoretical calculations from computer simulations, we will clarify a more detailed spatial distribution andcontribute to the design of the future fusion reactor.
Looking toward the realization of a future fusion power plant in which steady-state operation is required, we anticipate an important contribution.
In order to verify whether this projection will be accurate or not, currently in the LHD we are investigating qualities of the degree of losses at a highpressure level that is equivalently comparable to the future fusion power generation plant for plasmas of electrical resistance values lower than those of plasma used heretofore.
However, in the future fusion reactor, it is necessary to improve the cooling qualities because the heat generated inside the superconducting coils increases.
Together with pressing further forward with integration whether or not results from simulation research can be replicated in LHD plasma, building upon accumulated verified research we are aiming to contribute to the improved performance of LHD plasma andto the prediction of the future fusion energy power plant's plasma performance.
In the future fusion power plant, because steady state operation is demanded, in the LHD we are utilizing its special characteristics and advancing research on steady state plasmas.
The microwave collective Thomson scattering methodis considered an essential measuring method for the future fusion power plant, and, at present, it is scheduled to be one of the diagnostics devices affixed to the ITER International Thermonuclear Experimental Reactor.
In the future fusion reactor, in order to maintain continuous operation for more than one year, it is important to evaluate the amount of wear of these materials over a long period of time.
Further, in order to establish this method using microwaves and to apply this to the future fusion reactor, it is important to clarify those principles that inform why impurities are expelled from a plasma when a microwave is injected into the plasma.
In the future fusion reactor, the quantity of heat that the divertor will receive will grow larger, and there is concern that the heat flux will surpass the ITER design value substantially, which is approximately 20 megawatts per one square meter.
Thus, research related to the maintenance of steady state plasma and related issues, in addition to being one of the important experimental topics for demonstrating the LHD's special characteristics,is an extremely important research theme for advancing the design of the future fusion power plant where steady state operation is inevitable.
In the future fusion reactor, predicting the movement of high-energy ions is also important for the fusion reactor's design because high-energy helium ions that are generated by a nuclear reaction will heat and maintain the plasma.
Because a magnetic field is produced by sending an electrical current through an electromagnet, when considered through economic issues relating to the size of the electromagnet and the cost of electricity, confining high-pressure plasma by the weakest permissible magnetic field isimportant when seeking to make real the future fusion reactor.
In the future fusion reactor, based upon the prediction that this heat load will become larger, research is advancing on material development for the divertor board, and also on skillfully cooling plasma near the divertor board and reducing the heat load.
At the same time, we also investigated in detail the stability of plasma confined in the magnetic field container. Further, we actively conducted physics experiments for the purpose of clarifying the complicated phenomena that accompany high-performance plasma,and we deepened further the necessary academic understanding for the design of the future fusion power plant.
In plasma in the future fusion power plant, because the high-energy particles that are generated when plasma is burned will heat plasma and then continuously burn it, it is important to investigate in detail the special characteristics of confinement of high-energy particles and to clarify their behavior.
We can say that in the future, by advancing further engineering technologies relating to the superconducting coils and the vacuum vessel, and, further, by advancing our understanding of the complex interaction between the magnetic field lines structure and the plasma, the helical type will beable to demonstrate the great superiority of the design of the future fusion power energy plant.
In addition, in response to the high-temperature, high-density, and large-sized plasmas of the future fusion reactor, because a heating method that uses higher harmonic waves will have even higher absorption is anticipated, this method is being anticipated as one of the powerful methods for heating and controlling plasma.
In the future fusion reactor, helium will be generated through the fusion reaction of deuterium and tritium(both are isotopes of hydrogen). From the view that the helium amount of as much as 10% will be present in the plasma, it is possible that hydrogen isotopes and helium plasma will strike the wall, affect the wall material, and cause changes in the characteristics of the material.
Research Updates/ National Institute for Fusion Science Experiment-based research that aims at achieving the future fusion energy is moving forward in the Large Helical Device(LHD). Benefitting from recent, rapid advances in supercomputers, we are working too on integrated simulation research that reproduces computer simulations of the complicated behavior of extreme high-temperature plasma that has been observed in LHD experiments.
