Explainer | Why do many scientists oppose #Fukushima #radioactive waste discharge?
The release of treated waste water from the #NuclearPlant has begun, despite concerns from major scientific organisations
IAEA is monitoring the operation but many experts are questioning the amount of data being collected

Published: 2:05pm, 30 Aug 2023"Japan’s decision to start releasing around 30 years’ worth of treated radioactive waste into the #PacificOcean on #August24 has drawn criticism from some countries, including China, as well as some of the world’s leading scientific organisations.
"The plan to deal with the 1.3 million tonnes of contaminated water accumulated since the #FukushimaDaiichi #NuclearPowerPlant meltdown in 2011 includes removing most of the radioactive chemicals before it is discharged into the ocean.
[...]
"However, the ALPS has been shown to be unsuccessful in filtering out the other 62 radioactive chemicals present in the waste water, according to data from the Japanese ministry for economy, trade and industry (#METI).
"According to METI, around 70 per cent of ALPS-treated water still contained #radioactive substances other than #tritium by the end of 2020, and needed to be #repurified.
"The US-based National Association of Marine Laboratories (#NAML), which represents more than 100 labs, released a position paper in December 2022 [link in comments] that firmly opposed Japan’s plan over 'a lack of adequate and accurate scientific data' about its safety.
"NAML members include some of the world’s most influential marine research institutes, including the #ScrippsInstitution of #Oceanography at the University of California, San Diego."

From #NEI, the PRO #Nuclear lobby! TEPCO has a long history of "Dishonest Acts"?!! And why are we trusting them to test #FukushimaDaiichi #wastewater?!!
Tepco admits leaktightness test falsification
Staff Writer November 3, 2002
"Tokyo Electric Power (#Tepco) staff manipulated main steam valves to reduce leak rates during containment testing in 1991 and 1992, the company has admitted.
"Tepco admitted the '#DishonestActs' in a press release on 25 October. The company said that during the two annual inspections at #Fukushima Daiichi 1 (Fukushima I-1), plant staff knew that the containment leak rate was too high. When government inspectors carried out the leak tightness test the staff injected air via the main steam isolation valves to reduce the leak rate. It is reporteed elsewhere that the real rate was 2% per day compared to the allowed maximum of 0.45% per day. By manipulating the valve, the rate was reduced to 0.12% per day.
"Tepco said the plant had been shut down for additional leak rate inspections, and an external commission comprising five specialist lawyers had been assigned to oversee the investigation. The company could not say whether 'dishonest acts were conducted in the leakage inspections at all Tepco’s nuclear power stations other than the above-mentioned two inspections'; nor could it say whether other tests at that plant had been #falsified. All the company’s leak tests are now being examined.
"Once again, the power company found itself saying: 'Tepco sincerely regrets and apologises that such dishonest acts were conducted.' Tsunehisa Katsumata has taken over as head of Tepco following the resignation of Nobuya Minami. At a press conference Katsumata said the data falsification was 'the gravest crisis since the company was established', and that the company had lost so much 'it should start again from zero'. Shigemi Tamura is to be promoted to chairman, replacing Hiroshi Araki.
"Meanwhile, additional cases of covered up crack findings were also reported by Tepco. According to data Tepco provided to #METI, these cases involve flaws found in recirculation pumps and piping connecting the pumps to the primary circuit at Fukushima I-1 to I-5, at Fukushima II-3, and at #KashiwazakiKariwa 1 and 2. Unlike previously disclosed cases of concealed inspection results, the inspections at these reactors were carried out by Hitachi and Toshiba, rather than by GE.
"In one case, Hitachi has acknowledged that, while under contract for BWR inspection work for Tepco in 1992, it found cracks in neutron-measuring equipment at a BWR at Fukushima. Tepco officials then asked Hitachi personnel to delete the crack finds from reports that they wrote.
"According to a Hitachi spokesman, a senior official in Hitachi’s nuclear plant design division agreed to Tepco’s request because Tepco was a Hitachi client.
"As a consequence of these revelations, plans to build six new reactors totalling 9000MWe at three sites have been indefinitely frozen. This will halt over half the new nuclear capacity that Japan had intended to have in place soon after 2010, including Japan’s first two APWRs."
