Excerpts from presentation by Arnie Gundersen, Fairewinds Chief Engineer, Jul 16, 2015 (emphasis added):
- Are the meltdowns at Fukushima Daiichi over?… This catastrophe is not over… We should continue to be very worried.
- 3 of the nuclear cores at Fukushima Daiichi are in direct contact with groundwater. Nuclear power designers and engineers never anticipated that possibility.
- Fukushima Daiichi Units No. 1, No. 2, and No. 3 were destroyed… allowing holes and cracks to form… We know for sure that the Fukushima Daiichi containments are full of holes that allow groundwater to come in direct contact with each nuclear core.
- Groundwater is still leaking in and leaking out, at a rate of at least 300 tons per day… more than 1,500 days have passed… 23,000-tanker truckloads of radioactive water have already leaked into the Pacific Ocean. Worse yet, there is no end in sight.
- As Fairewinds anticipated, the ‘ice wall’ is a complete failure.
- Cesium, strontium and plutonium from Fukushima Daiichi will continue to bleed into the Pacific Ocean for decades because the groundwater flow is unmitigated.
- Japan’s press looks on silently due to the real threat and constraints of the government’s secrecy act… The true human, financial, and environmental costs of this nuclear power catastrophe are not publicized and discussed.
TEPCO reported on July 17 that Strontium-90 concentrations in the ocean outside Fukushima Units 3 and 4 are at record highs. Levels have spiked around 1,000% in 3 months.
Sr-90 measured between Unit 3 & 4 intake channel
Sr-90 measured at Unit 4 screen
* According to TEPCO’s July 17 report, the total level of all beta ray emitters (which includes Sr-90) was 1,200 Bq/L — yet the levels reported for Sr-90 were 1,500 Bq/L. When a similar occurrence happened last year, Asahi reported: “Strontium levels exceeded the all-beta readings in some instances, leading the utility to decide they were ‘wrong’.” TEPCO’s corrected data revealed much higher levels.
