On February 7th, a problem occurred at the Fukushima Daiichi nuclear power plant where water containing radioactive substances leaked from a building. The leakage is estimated to have lasted for about 40 minutes.

According to Tokyo Electric Power Company (TEPCO), the trouble at the Fukushima Daiichi nuclear power plant resulted in the leakage of up to 5.5 tons of water containing radioactive substances from the exhaust port of a building housing a water purification facility.

It is believed that much of the leaked water has seeped into the ground, with radiation levels around the site reportedly measuring about 240 times higher than normal. At the time of the incident, workers were conducting operations to flush the pipes of the purification facility with “non-radioactive water,” but due to a valve that should have been manually closed being left open, water leaked out for about 40 minutes.

The amount of radioactive substances contained in the leaked water is estimated to be as high as 22 billion becquerels, significantly surpassing the threshold requiring reporting to the authorities.

TEPCO intends to investigate the cause by conducting interviews with workers involved in the operation.

 

The water leaked for about 40 minutes. The water leaking from the Fukushima Daiichi Nuclear Power Plant contained 5.5 tons of sewage and seeped into the ground. The radiation dose was 240 times higher than that of the surrounding areas.

Tokyo Electric Power Company (TEPCO) has announced that water containing radioactive substances leaked from a purification device at the Fukushima Daiichi Nuclear Power Plant.

Before 9 a.m. on the 7th, it was found that water was leaking from the outlet of the purification device for contaminated water. According to TEPCO, during an inspection, it was discovered that out of 16 valves, 10 were supposed to be closed but were found to be open.

According to TEPCO’s estimates, approximately 5.5 tons of water may have leaked, containing 22 billion becquerels of radioactive substances such as cesium. However, it is believed that the majority has seeped into the soil, and there have been no significant fluctuations in the monitoring of nearby drainage channels.

TEPCO has prohibited entry to the area where the water leaked and is taking urgent measures such as collecting soil.

 

 

TEPCO apologizes for contaminated water leak; Fukushima Prefecture demands prevention of recurrence

In the wake of the leakage of radioactive water from the exhaust port on the outer wall of the high-temperature incinerator building at the Fukushima Daiichi Nuclear Power Plant, Tatsuya Tanami, the director of the plant, visited the Fukushima Prefectural Office on the 8th to apologize, saying, “I apologize to the people of the prefecture and to the broader society for causing concern and anxiety.” The prefectural authorities have demanded an investigation into the cause of the incident and measures to prevent recurrence.

Wataru Watanabe, head of the prefectural crisis management department, also mentioned an incident last October in which workers at the plant were exposed to radioactive wastewater, and handed a letter of request calling for thorough safety management. Director Tanami told reporters, “We want to identify the cause and report by next week.”

According to TEPCO, on the morning of the 7th, water leaked from the equipment while cleaning the contaminated water treatment system.
