Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Record Radiation Detected at Fukushima [AGAIN]

Record 1.9 million becquerels (Bq) per liter of radioactivity detected at Fukushima No.2 reactor: TEPCO

Radioactive substances have been found in water samples taken from deep underground layers at the crippled Fukushima Daiichi nuclear power plant, reported Tokyo Electric Power Company (TEPCO).

This is the first time TEPCO has admitted to detecting radioactivity in groundwater taken from a layer 25 meters beneath the No. 4 reactor well that faces the ocean, which implies radioactive substances have been leaking into the sea from yet another source.

Water sample taken on December 17, showed 6.7 becquerels per liter of Cesium 137 and 89 becquerels per liter of strontium and other beta ray-emitting radioactive substances.

“TEPCO officials are putting a new spin over their own report, saying that radioactive substances may have been accidentally mixed during the, according to a report.

Since July, TEPCO has admitted to three major incidents of contaminated water escaping from the power plant into the ocean, including two major leaks of highly radioactive water from storage tanks—a 300-ton spill in August followed by at least 430 liters in October this year.

Meantime, the company reported that density of beta ray-emitting radioactivity in groundwater has been rising since November. On December 19, the activity reached a record 1.9 million becquerels per liter.

[Note: The becquerel, the SI unit of radioactivity, is equivalent to one disintegration per second.]

Scale of potential catastrophe at Fukushima could dwarf a limited nuclear war.

80 Percent Chance of Major Catastrophe at Fukushima NPP

Posted by feww on November 7, 2013


Scale of potential catastrophe at Fukushima could dwarf a limited nuclear war

Four major factors would contribute to the probability of a major nuclear catastrophe occurring at Fukushima NPP during the fuel rods extraction operations at the plant’s No.4 reactor. —FIRE-EARTH Assessment

1. Probability of  significant earthquakes causing further damage to the reactor building during the recovery cycle: P≥ 0.9

2. Record of disastrous errors by the operator, TEPCO, especially after the 2011 Mega quake and tsunami struck: P≥ 0.9

3. State of fuel rods after the building was damaged by a hydrogen explosion in March 2011: UNKNOWN

4. Suitability of the  new “common pool” used for cooling the fuel rods: UNKNOWN

Based on the two known factors alone, the probability of a major catastrophe can be calculated at ≥ 0.81 [rounded down to eighty percent. ]

Fuel rod extraction process is scheduled to begin tomorrow, November 8, 2013, and would take about 14 months to complete, according to the operator.

The Spent Fuel Pool (SFP) at No. 4 reactor located on the upper floor of the building contains 1,533 units, includes 1,331 spent fuel units still emitting high levels of radiation, with the remaining units being unused fuel rods. The Tokyo Electric Power Company (TEPCO) is about to extract and relocate the rods.

TEPCO says removal of the fuels rods, which are currently in a precarious state due to an explosion in the reactor building caused by hydrogen buildup in 2011, is the first step in the decommissioning of the nuclear plant which has so far been subject to triple meltdowns.

The explosion may have damaged some of the fuel rods, and cause them to fuse together. Image source: Handout – Tokyo Electric Company (TEPCO).

FIRE-EARTH has a 100% record of forecasting disasters at Fukushima NPP. See blog content.
