– TV: Gov’t approves plan to ‘drain’ Fukushima nuclear waste into ocean — Professor: Monitoring necessary to detect ‘worrisome signals’ — Expert: “It’s completely unsafe… impossible to remove 100s of radioactive materials” — 1,200 radionuclides, only 62 reduced — Fisherman: “We can’t trust Tepco” (VIDEO) (ENENews, Jan 21, 2015):
NHK, Jan 21, 2015 (emphasis added): Regulators approve Fukushima wastewater drainage — Japan’s nuclear regulator has approved a plan by [TEPCO] to drain filtered wastewater from the firm’s crippled Fukushima Daiichi plant into the sea… The firm also plans to reduce the level of radioactive material in the water before releasing it into the nearby Pacific. On Wednesday, the Nuclear Regulation Authority approved TEPCO’s plan to install drainpipes and a pumping system and to reduce the level of radioactive cesium-137 to less than one becquerel per liter.
NHK Transcript, Jan 21, 2015: Japanese regulators have approved a controversial plan by [TEPCO]. They say TEPCO officials can flush filtered waste water into the ocean… Fisherman: “We can’t trust Tepco… If they proceed with their plan the situation will surely go back to how it was before. I’m worried the government and Tepco will act to suit themselves.”
Wall St Journal, Jan 21, 2015: Japan’s nuclear regulator has officially called on [Tepco] to work toward discharging low-level contaminated water… just two days after a worker fell into [a tank] used to store contaminated water… Tepco is using a processing system [that] is unable to take out the tritium [and] is reluctant to release it into the ocean to avoid… criticism from neighboring countries and some nations with a Pacific Ocean coastline… there is no detailed study about tritium’s long-time effect on animal genes. Mamoru Takata, a Kyoto University professor and expert on radiation’s long-term effects, said monitoring would be necessary to detect any worrisome signals.
TEPCO: [ALPS] is designed to remove most remaining radioactive contaminants
TEPCO (pdf): (ALPS) — Removal capacity: Reduce 62 nuclides below the density limit
Asahi Shimbun in Jan. 2012: “To prevent a further contamination of the sea [Tepco] plans to remove about 1,000 kinds of radioactive materials from water”
Japan Atomic Energy Agency (pdf), Feb 2014: TOPICS Fukushima — [W]e carried out detailed calculations… for 1,200 radionuclides, and the results were incorporated into a database.
Dr. Gordon Edwards, court-certified nuclear expert, Aug 8, 2014 (50:00 in): It can’t be dumped into the ocean, because it’s completely unsafe because of these fission products. They have built over 1,000 large tanks, huge tanks… that contain this very, very radioactively contaminated water. At the moment they’re trying to filter out these fission products… It’s impossible for them to remove all those hundreds of radioactive materials. They know how to remove about 62 of them, but there’s other ones that they cannot.
