To the Fukushima Daiichi nuclear power plant, the SDF began releasing water from the helicopter, and from the ground the riot police launched high pressure water discharge
At 9:48 am today, water discharge from the helicopter to the Fukushima Daiichi nuclear plant began.
At Fukushima Daiichi Nuclear Power Plant Unit 3 and Unit 4, the spent fuel storage pool can not be cooled, so there was a possibility of leakage of radioactive material as it was, so there was a request from the SDF and the police for water discharge.
Currently, the riot police are also preparing for high pressure water discharge, and work will start as soon as preparation is completed.
Details are as below.
From 9:48, water discharge by the SDF helicopter began.
NHK news to cooling work at Units 3 and 4
At the Fukushima Daiichi Nuclear Power Station, pools storing spent fuels at Units 3 and 4 are in a state where they can not be cooled, and if this state continues, radioactive substances may leak out to the outside, The SDF and the police are hurriedly preparing to discharge water from a helicopter in the sky and a water discharge car on the ground in response to the request of the government's headquarters.
The high-pressure water discharging car of the Metropolitan Police Team sits on standby, and as soon as preparation is completed, work starts. Water discharge to Unit 4 is undecided.

According to a press conference by the Minister of Defense, I planned to do yesterday but withdrew due to high radiation concentration, but I could not decide because of high concentration of water discharge from the ground, decided to judge today is the limit And that. At the time of dropping, we observe 4.13 mSv at an altitude of 1,000 feet (304.8 m), 87.7 mSv per hour at an altitude of 300 feet (91.44 m), the total amount will be observed after returning. In the afternoon the police are planning to discharge with a water discharge vehicle, after which the SDF will use 11 fire trucks to discharge water. Also, it is said that the SDF is transferring a US military pump used by TEPCO.

According to the figures of TEPCO's announcement, the observation results at the point of 100 to several tens of meters from Unit 3 are
Before dropping (9: 40): 3782 microsieverted hour
After dropping (10: 20): 3752 microsieverts per hour
It was said that there was no big change.

Water discharge to Unit 3 which needs to be repeated many times: Science: YOMIURI ONLINE (Yomiuri Shimbun)
In the present situation where cooling water can not be circulated, even if the pool is full, water injection of about 5 tons per hour is considered necessary. "If the cooling can not be done as it is, there is a danger that the fuel rods melt, there is no choice but to repeat the water discharge."
If electric power can be secured from the outside, it is possible to operate a large-sized pump that requires a large electric power. First of all, as an emergency measure, move the external power supply to the pump for sending water to the spent fuel pool in order to prevent the fuel from breaking and scattering of radioactive material to the outside air in large quantities.
In addition, we can operate emergency core cooling system (ECCS) which safely cooled nuclear reactor which did not work due to tsunami this time. Each nuclear reactor has two large pumps and can inject a large amount of water into the nuclear reactor. If cooling progresses at once, you can quickly bring it to a "cold state" where the nuclear reactor can be cooled safely and the nuclear reactor is stopped in a stable state.
Illumination will be resurrected, and work at night can be done as well. Furthermore, the water level gauge and the pressure gauge which are now unusable are operated, and it becomes possible to monitor the state of the nuclear reactor.
