Recently,’Scale 7.3′ earthquake data could not be secured
Fukushima aquatic products allowable limit 5 times radioactive material detection

It turned out that the two seismographs installed at Fukushima No. 1 (Fukushima Nuclear Power Plant) Unit 3, which caused a large-scale radioactive material leak accident, had been neglected even though they knew that they had failed since last year. As a result, it was not possible to obtain data on how the recent earthquake of magnitude 7.3, which occurred off the coast of Fukushima, affected nuclear power plant 3. Reported on the 23rd, “It was known that the seismometer was left broken and left in the process of Tokyo Electric Power responding to a question from a member at the Japan Atomic Energy Regulatory Commission meeting held on the 22nd.” The committee decided that it was necessary to continuously check the stability of the reactor building of Unit 3 due to the impact of the explosion during the Great East Japan Earthquake in March 2011. Tokyo Electric Power, which manages the Fukushima nuclear power plant, installed seismographs on the first and fifth floors of Unit 3 last March. However, the first-floor seismometer broke down due to flooding in heavy rain in July of last year, and the fifth-floor seismometer had an error in measurement data from October last year. Tokyo Electric Power Co., Ltd. has left broken seismographs for more than half a year, and this was revealed in the process of an inquiry by the Atomic Energy Regulatory Commission the day before. TEPCO did not explain the failure of the seismometer at a press conference held after the earthquake in Fukushima on the 13th. “We have not been able to secure a record of shaking of Unit 3, which will be used as an important measure for future earthquakes,” and said, “The committee criticized Tokyo Electric Power’s response as being problematic.” TEPCO said that it took time to analyze the cause of the error due to the delay in repair of the seismometer. Previously, Tokyo Electric Power Co., Ltd. confirmed the next day that among the contaminated water storage tanks stored on the site of the Fukushima nuclear power plant due to the earthquake on the 13th, it was released 5 days after the earthquake and was criticized. The Fukushima Nuclear Power Plant, which had an explosion during the 2011 Great East Japan Earthquake, has been decommissioned for over nine years with the operation being shut down. Of the six reactors, reactors 1 to 4 suffered damage from a tsunami, and core melting (melt down) and explosions occurred at reactors 1 to 3, causing major damage to the reactor building.

Meanwhile, 500 becquerels (㏃) of cesium per kilogram were detected in rockfish caught on the 22nd in the offshore of Fukushima Prefecture on the 22nd, (NHK) reported. It is five times the food allowance limit set by the Japanese government (100㏃ per kilogram) and ten times the Fukushima Prefectural Fisheries Cooperative Federation’s own standard (50㏃ per kilogram). It has been two years since February 2019 that radioactive substances exceeding the standard have been detected in Fukushima seafood. The Fukushima Prefectural Fisheries Cooperative Federation decided to stop shipping of rockfish until safety was confirmed. By Kim So-yeon, staff reporter [email protected]
