IAEA report confirms safety of discharged Fukushima water
An International Atomic Energy Agency task force has confirmed that the discharge of treated water from Japan’s Fukushima Daiichi nuclear power plant is proceeding in line with international safety standards. The task force’s findings were published in the agency’s fourth report since Tokyo Electric Power Company began discharging Fukushima’s treated and diluted water in August 2023.
More information can be found on the IAEA’s Fukushima Daiichi ALPS Treated Water Discharge web page.

The possibility of enhancing the ratio of output to input power Q in a simple mirror machine by polarizing deuterium-tritium (D-T) nuclei is evaluated. Taking the Livermore mirror reference design mirror ratio of 6.54, the expected sin2 ϑ angular distribution of fusion decay products reduces immediate losses of alpha particles to the loss cone by 7.6% and alpha-ion scattering losses by ∼50%. Based on these findings, alphaparticle confinement times for a polarized plasma should therefore be 1.11 times greater than for isotropic nuclei. Coupling this enhanced alpha-particle heating with the expected > 50% D-T reaction cross section, a corresponding power ratio for polarized nuclei, Qpolarized, is found to be 1.63 times greater than the classical unpolarized value Qclassical. The effects of this increase in Q are assessed for the simple mirror.
