• Note (General): Presently, the Power Reactor and Nuclear Fuel Development Corporation (PNC) is investigating the best way to treat high-level radioactive nuclear wastes from reactors. As part of their basic research on the transmutation of fission products, PNC developed a high-power CW electron linac for various applications, in particular for studying the use of strong gamma-rays for transmuting the medium-lived fission products (MLFP) of Sr-90 and Cs-137. As the results of studies of transmutation by photoreaction have shown, high-flux and high-energy gamma-rays ($\sim$ 15 MeV) are needed. However, to make an approach feasible it is very important to generate the gamma-rays at a reasonable cost. To increase the intensity of the gamma-rays, a high-current electron beam and a high-power laser are needed. This paper reports our findings which show that to generate gamma-rays by inverse Compton scattering effectively, the photons accumulated in a optical resonator must intensify the monochromatic gamma-ray flux by the collisions of inverse Compton scattering with electrons. The method we discuss employs inverse Compton scattering with an optical resonator composed of very high-reflectance, low-absorptance mirrors. With advances in technology, the flux of gamma-rays that can be attained is of the order of 10$^{18}$, and its efficiency is 0.9\% using this method. IF future technological progress results in a mirror with a reflectance of 8N and absorptance of 0.001ppm, then it might be possible to achieve a flux of the order of 10$^{20}$, and an efficiency of more than 30\%. In the case of a concentric resonator, the density of the photon's beam at the interaction point can be higher than that in a confocal type, so that a gamma-ray flux of the same order as the 8N case may be achieved.; None
