On 10/10/2012, Tepco investigated the inside of PCV in reactor1.
The water level was 2.8m from the bottom of PCV1. The highest dose was 11.1 Sv/h, which is enough to kill a person in one hour.
The strange point is they detected this highest reading in the penetration tip, which is 5.8m above from the water level.
Inside of PCV, the higher above from the bottom of PCV, the higher the radiation level goes.
At 50cm above from the water level, it was 4.7 Sv/h.
At 5.8m above from the water level, it was 9.8 Sv/h.
Due to the Tohoku-Chihou-Taiheiyou-Oki Earthquake which occurred on March 11, 2011, TEPCO's facilities including our nuclear power stations have been severely damaged. We deeply apologize for the anxiety and inconvenience caused.With regard to the accident at Fukushima Daiichi Nuclear Power Station, on April 17, 2011, we have compiled the roadmap towards restoration from the accident and on July 19 we accomplished the Step1 target "Radiation dose is in steady decline". Then on December 16 we confirmed the accomplishment of the Step 2 target "Release of radioactive materials is under control and radiation doses are being significantly held down".In addition, on December 21, 2011, we have compiled the "Mid-to-long-Term Roadmap toward the Decommissioning of Fukushima Daiichi Nuclear Power Units 1-4, TEPCO".In addition to the maintenance of the plant's stable condition, we will implement Mid-to-Long Term countermeasures towards the decommissioning of Fukushima Daiichi Nuclear Power Units 1-4 to enable evacuees to return to their homes as soon as possible and reduce the anxiety of the people in Fukushima and the whole nation as soon as possible.
