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 (TEPCO) 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 radiation-induced outgassing (RIO) was measured for a molecular sieve material used in sorption pumps (Linde Molecular Sieve Type 13X) exposed at 20°C to 60Co gamma radiation at a dose rate of 9.0 × 104 rad/h. The measured outgassing rate was found to be (7.03 ± 2.21) × 10-10 Pa ℓ /(cm2.s).Mrad-1h-1, which is consistent with values determined previously for various metals. This RIO is equivalent to a thermal bakeout at only 30°C. It was concluded for this material that the RIO is not a viable alternative to thermal bakeouts.
