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.

A behavior model for fission gas in irradiated liquid-metal fast breeder reactor fuels is applied in a computer code. The subroutine LANGZEIT calculates the “long-time” kinetics processes during steady-state operation. The results are used as initial conditions for the subroutine KURZZEIT, which permits the description of the bubble growth during rapid overpower transients. This model has been applied to the SNR-300-Mark I core. The calculations indicate a prompt precipitation of fission gas during the reactivity excursions, which results in a dampening effect on the reactivity ramps.
