Record cesium levels at Fukushima

TEPCO reveals record cesium level in Fukushima No. 1 well
A record high level of radioactive cesium has been found in groundwater beneath the crippled Fukushima No. 1 nuclear power plant, it operator TEPCO revealed.


RT,
14 February, 2013



On February 13, Tokyo Electric Power Co. reported 37,000 becquerels of cesium-134 and 93,000 becquerels of cesium-137 were detected per liter of groundwater sampled from a monitoring well earlier that day.

Water samples were taken from the technical well, located next to the second power unit, some 50 meters from the coast. These figures (the total reading) are the highest of all the cesium measurements taken previously.

Experts do not rule out that radioactive water is leaking from an underground tunnel, which is located close to the second power unit on the seashore.

However, no exact reason for such a significant increase of radioactive cesium content in the groundwater has been given so far.

Japanese newspaper The Asahi Shimbun reported that the amount of radioactive chemicals seems to be increasing. On Feb. 12, the same sampling well had produced a combined cesium reading of 76,000 becquerels per liter.

Earlier Japan's nuclear regulator slammed the stricken Fukushima plant operator for incorrectly measuring radiation levels in contaminated groundwater at the site.

The Nuclear Regulation Authority (NRA) accused TEPCO of lacking basic understanding of measuring and handling radiation almost three years since the reactor meltdowns at the Fukushima No. 1 nuclear power plant.

On Thursday, fears of new leaks surfaced in Japanese media, as the same newspaper reported two cracks in a concrete floor of the No. 1 facility near radioactive water storage tanks.

TEPCO suggested some contaminated water from the melting snow may have seeped into the ground through the cracks, stretching for 12 and 8 meters.

The leakage of radiation-contaminated water is posing a major threat to Japan’s population and environment and to the international community since the March 2011 disaster.


Radioactive cesium levels “never seen before” at Fukushima

New record as amount in groundwater nearly doubles in 24 hours — Officials admit ‘may be new leak’ — IAEA urges ‘resumption’ of dumping contaminated water in ocean; ‘All options’ need to be on table



AFP, Feb. 13, 2014: Fukushima should eye ‘controlled discharges’ in sea: IAEA — The [IAEA] urged Japan to consider “controlled discharges” into the sea of contaminated water [...] “This would require considering all options, including the possible resumption of controlled discharges to the sea.” [...] local fishermen, neighbouring countries and environmental groups all oppose the idea. [...] radioactive groundwater [...] leaking into the ocean [is] an ongoing problem that has stoked fears about dangers posed to marine life and the food chain. [...]

Shanghai Daily, Feb. 13, 2014: TEPCO is still eyeing dumping toxic water into the Pacific Ocean as it fails to contain in makeshift storage tanks [...] a massive daily influx of water needed to cool the battered reactors, while nuclear experts believe that other methods need to be traversed before contaminating the ocean. Dumping radioactive water into the ocean is of grave concern to local fisheries cooperatives as the potential for radioactive materials to spread to marine life remains a distinct possibility [...] NRA Chairman Shunichi Tanaka [...] said [...] TEPCO is still utterly inept when it comes to taking accurate readings of radioactivity [...] and “lacks a basic understanding of measuring and handling radiation.”

NHK, Feb. 14, 2014: IAEA: Consider discharging contaminated water — [The IAEA] advised [Tepco] to examine all options to treat contaminated water. These include resuming controlled discharges of radioactive water into the sea. [...] [IAEA's Juan Carlos Lentijo says] the situation remains very complex [and requires] considering all options, including the possible resumption of controlled discharges to the sea.

Xinhua, Feb. 13, 2014: [TEPCO] said Thursday that samples of water tested contained radioactive cesium at levels never seen before by the embattled utility. TEPCO [is] admitting there may be a new leak at the site of a well located just 50 meters from the adjacent Pacific [...] [It] failed to locate the source of the leak, in another major failing [...]

Tepco Handout, February 13, 2014: “The highest dose among the results previously announced” — Underground water at 130,000 Bq/L of Cs-134, 137. Previous record set Feb. 12 with 76,000 Bq/L of Cs-134, 137.
