I agree it is required, though, I feel N-power energy is already old technology (even unsafe). Advanced country like Japan can forget N-power plant and should use solar, wind, water power instead of N-power even they are expensive. So for worldwide, N-power is still required – I agree. However, even it is cheap energy, Japan should not use N-power, which is higher risk in Japan than other countries. We already have experience. I prefer safer country even I pay double for the electric energy.
