They also agreed to cooperate on military affairs and rehabilitation following natural disasters, as well as research and development on nuclear energy for peace.
SEOUL, March 14 (Yonhap) — It was shocking when the authorities halted operation of a nuclear reactor at the Gori Nuclear Power Plant in Busan, 450 kilometers south of Seoul, following a belated report of electricity failure last month.
What makes us even more concerned is that the accident had not been reported for about a month.
The Gori-1 reactor officials said they did not sound the alarm because the power was restored shortly in 12 minutes. When the meltdown of the Fukushima reactor was reported, South Korean nuclear power plant authorities boasted there would be no such problems with nuclear reactors in the country as they are well equipped with good power supply systems in contingencies.
Radiation inside the reactor 2 containment vessel at the Fukushima No. 1 nuclear plant has reached a lethal 73 sieverts per hour and any attempt to send robots in will require them to have greater resistance than currently available, experts said Wednesday.
Exposure to 73 sieverts for a minute would cause nausea and seven minutes would cause death within a month , Tokyo Electric Power Co. said.
The experts said the high radiation level is due to the shallow level of coolant water – 60 cm – in the containment vessel, which Tepco said in January was believed to be 4 meters deep. Tepco has only peeked inside the reactor 2 containment vessel. It has few clues as to the status of reactors 1 and 3, which also suffered meltdowns, because there is no access to their insides.
The high radiation level can be explained by the low level of the water, which acts to block radiation.
“The shallowness of the water level is a surprise, and the radiation level is awfully high,” Misawa said.
While the water temperature is in a safe zone at about 50 degrees, it is unknown if the melted fuel is fully submerged, but Tepco said in November that computer simulations suggested the height of the melted fuel in reactor 2′s containment vessel is probably 20 to 40 cm, Tepco spokeswoman Ai Tanaka said.
Tepco inserted a radiation meter into the containment vessel of reactor 2 Tuesday for the first time, measuring aerial radiation levels at several points inside the vessel. The readings were for 31.1 and 72.9 sieverts per hour.
Tepco has not been able to gauge the water depths and radiation levels of the containment vessels for reactors 1 and 3.
According to experts, even though high radiation in the containment vessel means additional trouble for Tepco, it is unlikely to affect the timing of decommissioning the three crippled reactors, which Tepco said will take 40 years.
An update on the Fukushima situation with Arnie Gundersen of Fairewinds Associates discusses the recent discovery of incredibly high decay rates in the containment area of reactor 2 and resulting bioaccumulation, the mainstream media failures regarding this event, the lack of testing of imported products, leukemia rates in our children and grandchildren, the debris and ocean contamination and the shocking revelation that blows the lid off of a conflict of interest that has the potential to affect the health and safety of Canadians and much more, a MUST listen.
