– Jiji: No solution seen for Fukushima’s radioactive water — Kyodo: Toxic ocean leakage to go on into 2020s — Experts: “High potential for marine life and human health effects through ingestion over generations” (ENENews, Dec 16, 2013):
Jiji Press, Dec. 16, 2013: No Solution in Sight for Fukushima N-Plant Tainted Water […] No solution is in sight as [Tepco] struggles with ever-increasing amounts of radioactive water […] The situation has improved little in the [past] six months […] very high-level radioactive water has been detected under the ground […] TEPCO detected 1.8 million becquerels of radioactive materials per liter of water collected on Thursday from an observation well some 40 meters from the seawall, the highest on record.
Kyodo News, Dec. 11, 2013: A government panel […] estimated that the utility will not be able to fully address the risks of water leaks by the end of fiscal 2020. […] “If measures are taken smoothly, a large part of the risks (posed by leaks from tanks) will be reduced around the end of fiscal 2020, but the amount of toxic water could surpass the tank storage capacity depending on the situation…and risks associated with keeping a large amount of tritium-water will remain,” the report said.
Estimate of Consequences from the Fukushima Disaster, Nordic PSA Conference (nuclear utilities in Finland and Sweden), September 2011: Some estimates of contamination of ocean waters were performed […] More than 1.1e17 Bq [110 quadrillion becquerels] of Cs137 in total is estimated to have been released into the ocean. With respect to bio-accumulation and weighting factors for fish and other sea fauna a long-term cycle can be expected and high potential for marine life, sea-birds and human health effects through ingestion over generations.
