Nuked Fukushima Plant: New High Radiation Areas Found

More Radiation Hotspots Found at Fukushima NPP

The operator of Japan’s nuked Fukushima plant has found two new radiation hotspots near storage tanks holding highly irradiated water, raising fear of new leaks as the extent of the disaster widens.

The news follows a press release earlier this week in which Tokyo Electric Power Co (TEPCO), a name now synonymous with incompetence, treachery and cowardice, admitted contaminated water with dangerously high levels of radiation was leaking from one of its purpose-built storage tanks.

The first of the two highly irradiated areas was found near the tank No. 4 in the group B in the H3 area, with a reading of 100mSv/h, and the second was near storage tank No. 10 in the group A in the H3 area, where the reading was 70mSv/h.

The company’s latest press release is posted below.

Press Release (Aug 22,2013) – Water Leak at a Tank in the H4 area in Fukushima Daiichi Nuclear Power Station (Follow-up Information 10)

This is follow-up information on the “water leak at a tank in the H4 area in Fukushima Daiichi Nuclear Power Station” found on August 19.

From around 11:00 AM to around 3:00 PM, we conducted full inspections (appearance inspections and dose measurement) on the flanged tanks in the other areas, which are of the same type as the tank from which water has leaked.

Neither leak nor puddle was found by the appearance inspections on the tanks and the drain valves. However, 2 locations locally showing high dose rates were found around the H3 area tanks.

The surfaces of these locations were dry, and we confirmed that water flowed out neither into the inside of the dike nor into the outside of the dike. We also confirmed that the water levels of these tanks remain unchanged after receiving water.

[High dose rate locations, the surface dose equivalent rates at these locations (γ and β rays (70μm dose equivalent rate)), and tank water levels]
” Near the bottom flange of the tank No. 4 in the group B in the H3 area: 100mSv/h and approx. 97% of the full water level
” Near the bottom flange of the tank No. 10 in the group A in the H3 area: 70mSv/h and approx. 95% of the full water level

No locations around the other tanks and drain valves showed high dose rates.

What is a lethal dose of radiation from a single Exposure?

Studies of the 1945 atomic bombing at Hiroshima and Nagasaki show that 100 percent of victims whose bodies were exposed to 600,000 millirems (6,000 mSv) died from radiation. About 50 percent of victims who received  450,000 millirems (4,500 mSv) of radiation also died.

Disaster Deepens at “Nuked” Fukushima Plant

More tanks may be leaking contaminated water: NRA

Japan’s Nuclear Regulation Authority (NRA) has raised the severity of the Fukushima crisis from a level 1 “anomaly” to a level 3 “serious incident” on the International Nuclear Event Scale (INES), an international scale for radiological releases.

[NOTE: Each step increase on INES represents a 10-fold jump in severity.]

The plant’s operator, Tokyo Electric Power Co (TEPCO) said on Tuesday that highly contaminated water was leaking from a storage tank; however, the NRA fears that more of the storage tanks may be leaking.

NRA Chairman has likened the nuked Fukushima plant to a house of horrors at an amusement park. “I don’t know if describing it this way is appropriate, but it’s like a haunted house and, as I’ve said, mishaps keep happening one after the other,” he told reporters. “We have to look into how we can reduce the risks and how to prevent it from becoming a fatal or serious incident.”

Meantime, the deadly farce continues…

TEPCO: Press Release (Aug 21,2013) Water Leak at a Tank in the H4 area in Fukushima Daiichi Nuclear Power Station (Follow-up Information 6)

This is follow-up information on the “water leak at a tank in the H4 area in Fukushima Daiichi Nuclear Power Station” found on August 19.

We would like to announce analysis results on seawater near the exit of the side ditch of the south water outlet and water in the side ditch in front of the core warehouse, sampled yesterday (on August 20), as follows.

As a result of the analysis this time, the densities in seawater near the exit of the side ditch of the south water outlet were found to fall within the fluctuation ranges of the past densities measured on a regular basis in seawater near the exit of the side ditch of the south water outlet. The densities in water of the side ditch in front of the core warehouse were found almost unchanged from the results obtained yesterday.

<Seawater of the south water outlet (near the exit of the side ditch) (sampling performed at 2:20 PM on August 20)>
Cesium-134:Below the detection limit value [the detection limit value: 1.1Bq/L (1×10^-3Bq/cm³)]
Cesium-137:1.8Bq/L (1.8×10^-3Bq/cm³)
All β:Below the detection limit value [the detection limit value: 19Bq/L (1.9×10^-2Bq/cm³)]

<Water of the side ditch in front of the core warehouse (sampling performed at 11:40 AM on August 20)>
Cesium-134:Below the detection limit value [the detection limit value: 19Bq/L (1.9×10^-2Bq/cm³)]
Cesium-137:Below the detection limit value [the detection limit value: 27Bq/L (2.7×10^-2Bq/cm³)]
All β:93Bq/L (9.3×10^-2Bq/cm³)

We are to continuously conduct analysis today on seawater of the south water outlet (near the exit of the side ditch) and water of the side ditch in front of the core warehouse.

For the past sampling results, please refer to the following page on our website:  http:// www.tepco.co.jp/en/nu/fukushima-np/f1/smp/index-e.html

The International Nuclear and Radiological Event Scale (INES)

The INES, a logarithmic scale, which was introduced in 1990 by the IAEA to enable prompt communication, classifies the intensity of nuclear incidents as follows:

[NOTE: Each step increase on INES represents a 10-fold jump in severity.]

7 – Major Accident [Chernobyl disaster, criticality accident, April 1986]

6 – Serious Accident [e.g., Kyshtym incident, Mayak, former Soviet Union, steam explosion released up to 80 tons of highly radioactive material into the atmosphere, September 1957. ]

5 – Accident With Wider Consequences [e.g., Three Mile Island accident  Pen State, U.S., partial meltdown release radioactive gases  into the environment, March 1979.]

4 – Accident With Local Consequences [e.g., Sellafield, UK, at least 5 incidents reported between 1955 to 1979]

3 – Serious Incident [e.g., Vandellos NPP, Spain, fire destroyed control systems; the reactor was shut down, July1989]

2 – Incident [e.g., Forsmark NPP, Sweden, a backup generator failed, July 2006]

1 – Anomaly [e.g., TNPC, France, 1,600 gallons of water containing 75 kilograms (170 lb) of uranium leaked into the environment,  July 2008]

0 – Deviation (No Safety Significance) [e.g., Atucha, Argentina – Reactor shutdown caused by tritium increase in reactor encasement, December 2006.]

Fukushima SNAFU

300 tons of highly contaminated water leaked from storage tank

Highly radioactive water has leaked from a storage tank into the ground at Japan’s crippled Fukushima plant, the operator Tokyo Electric Power Company (TEPCO) says.

The ongoing calamity is by far the most serious incident since the clean up operation began at the world’s worst nuclear disaster site since Chernobyl meltdown.

The contaminated water contains at least 80 million Becquerels of radiation per liter, about 540,000 times the normal background level.

According to some reports, the water level inside the leaking storage tank had dropped by about 300cm (10 feet) before anyone noticed.

TEPCO has announced its intention to remove some 1,300 highly irradiated spent fuel rod bundles weighing more than 400 tons from its crippled storage pools later this year.

[It’s hoped that TEPCO will NOT be allowed to do so. Any such climacteric and potentially apocalyptic operation should only be done by an international (non-Japanese) team of competent engineers. Editor]

At least 350,000 tons of radioactive water is currently stored at the tsunami-crippled Fukushima Daiichi nuclear power plant.
