The position of 85 water storage tanks in the Fukushima Daiichi nuclear power plant is shifted. What problems are exposed by Japanese media analysis?
[Global Times Comprehensive Report] Japan's Tokyo Electric Power Company announced on the 17th that due to the impact of the earthquake with the largest magnitude of 6 (Japanese standard) in Miyagi and Fukushima prefectures on the 16th, 85 nuclear sewage at the Fukushima Daiichi Nuclear Power Plant was stored. The position of the water storage tank shifted, and six containers containing protective clothing and iron filings used in the decommissioning operation of the reactor overturned.
Japan's Kyodo News said on the 18th that this shows that the Fukushima nuclear power plant, which has been carrying out reactor scrapping operations for a long time, still needs to do a good job in risk management against natural disasters such as earthquakes and tsunamis.
Affected by the earthquake, the water supply in Fukushima Prefecture was interrupted, and local residents had to queue for water on the 18th.

Kyodo News pointed out that the Fukushima nuclear power plant in the earthquake exposed three problems.
The first is the emergency mechanism. After the earthquake, the cooling of the fuel pools of Unit 5 of the Fukushima Daiichi Nuclear Power Station and Units 1 and 3 of the Second Nuclear Power Station automatically stopped; the water level of the storage tank connected to the fuel pool in Unit 2 of the First Nuclear Power Station Descended, and the cooling was stopped manually.
It took about 7 and a half hours to recover.
The person in charge of TEPCO said that in order to prevent equipment failure, the time for stopping cooling can be shortened from the results.
Secondly, there is still a large amount of spent fuel in the reactor building of the Fukushima Daiichi Nuclear Power Plant. There are still 1,007 fuel rods in the fuel pool of Units 1 and 2.
TEPCO announced that the time for removing fuel rods from the fuel pool has been postponed several times.
In addition, after the earthquake, TEPCO's announcement on Twitter was delayed, and the Ministry of Economy, Trade and Industry issued an instruction to quickly release the information.
"Asahi Shimbun" said in an editorial on the 18th that the earthquake off the coast of Fukushima Prefecture reminded many people of the Great East Japan Earthquake in 2011, and they were worried that the earthquake would affect the nuclear facilities along the coast, especially the Fukushima Daiichi Nuclear Power Plant.
