TEPCO, operator of crippled Fukushima nuclear power plant (NPP), reported that high densities of tritium and strontium were found in the observation hole at the east side of the Unit 1-4 Turbine Buildings of the nuclear power plant.
In a press release issued on July 29 the readings are as follows:
B1-1: Unit 2 water intake power cable trench (seawater piping foundation part)
– Sampling on July 26:
Tritium 8,700,000 Bq/L (8,700Bq/cm3) (new)
Chlorine 8,000ppm (previously announced)
Cesium-134 750,000,000Bq/L (750,000Bq/cm3) (previously announced)
Cesium-137 1,600,000,000Bq/L (1,600,000Bq/cm3) (previously announced)
All-β 750,000,000Bq/L (750,000Bq/cm3) (previously announced)
On July 22, TEPCO admitted that some radioactive water is probably leaking into the sea from compound of the nuclear plant. They also announced that they plan to build "frozen water wall" to prevent the leakage. This would be the first time such technology is used. Feasibility test should start in September (FD).
On July 27, utility reported that the water in the underground passage, which runs under the turbine building of reactor 2, contained 2.35 billion becquerels of cesium per liter, roughly the same as that measured right after the crisis began in spring 2011. (JT)
The levels are millions of times higher than the legal limit for cesium-134 and 137 in water under normal circumstances. The government limit for cesium-134 is 60 becquerels per liter, while the limit for cesium-137 is 90 becquerels per liter (WSJ).
