It’s why Japan experiences 1,500 earthquakes per year, proving the validity of the saying, “think before you design/build”. The movement of groundwater may be impacted by the removal of the water from the wells. Fukushima, dieci anni dopo: perché la tragedia nucleare non è ancora finita (e quanto tempo servirà ancora) Dove siamo oggi a dieci anni da quel terribile evento? Groundwater was estimated to flow into the ocean from the mountain side based on ground water flow modeling22. Posted by dunrenard | Three reactor buildings were severely damaged by hydrogen explosions. Robert Hunziker: It is a direct consequence of the 2011 meltdown. No. Leave a comment. Fukushima / 2020 5 .8 4 voti I lavoratori della struttura di Fukushima Daiichi in Giappone rischiano la vita e rimangono nella centrale nucleare per prevenire la distruzione totale dopo che la regione è stata devastata da un terremoto e uno tsunami nel 2011. But if this approach is rejected, alternative disposal plans comprise evaporating the wastewater into the air, or expanding the existing storage capacity and continuing to store the water either on land or underground. GENSUIKIN has local organizations as members, consisting of labor unions, women’s organizations, youth organizations and civil society groups in all 47 prefectures of Japan. Fukushima oggi, le foto della città e della centrale nucleare a 10 anni dal disastro | Sky TG24. The Science, ICT, Broadcasting and Communications Committee of the National Assembly of the Republic of Korea has already passed a resolution requesting that the Japanese government establish safer measures when processing the contaminated water. At the end of its atomic-scale trip it delivers most of its ionising energy in one relatively confined track rather than shedding energy along its path like higher-energy particles. Grouting of surfaces (to prevent from soaking rainwater into the ground) (from Oct. 2014). Korea called Tuesday for the U.N. nuclear watchdog to play an “active” role in ensuring Japan’s transparent and safe handling of contaminated water from its crippled Fukushima nuclear power plant, the foreign ministry said.Ham Sang-wook, deputy foreign minister for multilateral and global affairs, made the call during an annual policy consultation with Massimo Aparo, the head of the International Atomic Energy Agency (IAEA)’s department of safeguards.“On the occasion of this consultation, our side stressed the contaminated water issue is a crucial matter that can affect the safety and environment of Japan’s neighboring countries and of the entire international community,” the ministry said in a press release.“It asked the IAEA to play an active role in terms of securing transparency and verifying the safety in all processes of the Japanese government crafting measures to dispose of the water and disposing of it,” it added.Amid public concerns over Japan’s possible discharge of the radioactive water into the sea, Seoul has repeatedly called for Tokyo to transparently share related information and stressed its “foremost priority” on the safety of citizens.Last month, Tokyo was expected to finalize its plan to dispose of the tritium-laced water. Key among the objections made by Greenpeace to the Government’s plan is that the ALPS was not designed to remove carbon-14, a hazardous radionuclide whose presence in the wastewater was only acknowledged by TEPCO in late August. Please see the end of the article for action steps. A surface water concentration of 3H at 184 (± 2) Bq/L was detected in rice paddy fields at 1.5 km from the FDNPP plant12. As we explain above, there are many problems about the disposal of contaminated water into the Pacific Ocean. The greater Tokyo Olympic venues had activities similar to sample sites in the US. It takes years and decades before the true impact of radioactive isotopes are fully recognised in humanoids. Ricevi le notizie più importanti di politica, mondo, cronaca, spettacolo, le analisi e gli aggiornamenti. I didn’t even imagine things were so bad,” says forester Akimoto Kimio, who visited a plantation in Tomioka, about 10 kilometers away from the crippled Fukushima Daiichi nuclear power plant. These data show that remediation emphasized the Olympic venues over cleaning other contaminated parts of Japan.”, https://www.fairewinds.org/demystify/radioactive-isotopes-measured-at-olympic-and-paralympic-venues-in-fukushima-prefecture-and-tokyo-japan?fbclid=IwAR25v6TXTqn7TOPNxRoBkwLzF9r6_YLEPi3IbcMlpNnkA5s1tFhh5x4MAVY, November 15, 2020 However, in August 2018 Japanese media reported that ALPS had consistently failed to eliminate a variety of other radioactive elements, including iodine-129, ruthenium-106, and strontium. Along those lines, it is important to note that ocean disposal of nuclear/radioactive waste has been banned via international treaties, e.g., The London Convention bans dumping radioactive waste in the seas. Leave a comment, Workers at TEPCO’s Fukushima Daiichi Nuclear Power Station work near above-ground storage tanks in 2013. Tritium cannot be eliminated by ALPS at all. Meanwhile the radioactivity of tritium in flowing water was below 0.01 Bq/L. In Japan, the limit for tritium release into the ocean is 6.0 × 104 Bq/L in a typical nuclear facility, but in the case of the FDNPP, 1500 Bq/L is the regulatory limit for tritium effluent19. Another option is to evaporate the wastewater into the air, according to the International Atomic Energy Agency. But after nine years and eight months, it returned to Tomioka on November 4. Investigation of 3H in precipitation may be one of the easiest ways to confirm the release of 3H into the atmosphere. “Tritium is a beta emitter with low energy so causes damage to the DNA leading to genetic damage and affecting reproductions.” It will depend upon the radioisotopes contaminants in the water. There are currently 1,044 tanks at the site. (Photo: The damaged Fukushima Daiichi Nuclear Power Station as seen during a sea-water sampling boat journey. TEPCO must not force the disposal. TEPCO estimates that there are 860 trillion becquerels of tritium in the contaminated water as a whole. As it stands, says the report, it looks like 72% of the water currently in storage tanks will have to be processed again – and questions remain as to how effective this will be. Posted by dunrenard | (There is nothing positive about that rationale. A contaminated forest would be particularly hazardous in the event of a landslide, because the mud flow is likely to contain radioactive substances. Fukushima 2020 | Fukushima Daiichi, Radioactive Water, Sea release, Taiwan | (Yonhap), http://www.koreaherald.com/view.php?ud=20201120000596. In August 2019, the company that runs the power plant, Tokyo Electric Power Company Holdings Inc., announced that storage space for the contaminated water would run out in 2022. Nineteen local assemblies in Fukushima Prefecture have submitted a written opinion opposing the disposal. The 3H observed in sump water ranged from 15 to 31 Bq/L and was almost constant (average 20 Bq/L). Ever since an earthquake and tsunami triggered a triple meltdown at the facility, the forest has been abandoned. The contaminants of the massive quantities of nuclear water will include radioactive isotopes such as cesium, tritium, cobalt and carbon-12 and may take from 12 to 30 years to decay. Coloro che abitavano nella zona rossa, che si trova entro un raggio di 20 chilometri dalla centrale nucleare, non possono tornare nelle proprie case a causa degli altissimi livelli di radiazioni. The officials say an analysis of image processing shows the first blast damaged the fourth floor. However, Greenpeace said TEPCO “continues to misrepresent and selectively ignore basic science facts on radioactive tritium.”. Their parents were children in 1986. This is not acceptable. All of which supports the viewpoint that radioactive contaminated water should never be dumped into the ocean. Greenpeace, il pericolo di Cernobyl aggravato dai cambiamenti climatici. At a regular press briefing Thursday, MOFA spokesperson Joanne Ou (歐江安) said the Japanese government has not yet made a final decision on the issue, and MOFA will seek clarification. At FDNPP, 8.51 × 1013 Bq/month at 1.1 MW operation was produced by ternary fission4. (see supplementary data).
