We regret that the official live streaming of NHK WORLD TV on USTREAM will be discontinued on March 25 at 24:00 JST. However, you can continue to watch our official live streaming on both NHK WORLD website and Livestation. nhk.or.jp/nhkworld/

The following is information from the live video news feed as it comes in:

Wednesday (Japan Time)
Radiation levels exceeding health limits for infants have been detected in a water purification plant supplying Tokyo water.
A Tokyo water purification manager, El Yoshida, has advised in a press conference (video) that infants in 23 wards of Tokyo and some places in the city of Tama should not be given tap water.
The radiation detected in the water and in soil is thought to be because of rain.
High radiation has been detected in soil about 40km from the plant.

Reactor update:
Reactor 1: There is damage to the core from cooling problems. Power lines have been attached.
Reactor 2: There is damage to the core from cooling problems. Containment damage is suspected. Power lines have been attached.
Reactor 3: There is damage to the core from cooling problems. Containment vessel damage is possible. A spent fuel pond has been partly refilled with water after running low. Power lines have been attached.
Reactor 4: The reactor was shut down prior to earthquake. There have been fires and an explosion in spent fuel pond. Water levels have partly been restored. Power lines have been attached.
Reactors 5 & 6: These reactors are shut down. The temperature of spent fuel pools have been lowered after rising high. Power lines have been attached.

Tuesday (Japan Time)
The government suspended some farm products (spinach, milk, yogurt) from around Fukushima on Monday, due to radiation.
The minister said even eating these products shouldn’t impact health, unless they are consumed over a long period.
The government has said people should stay calm and not to overreact.
Before the earthquake, in relation to sea walls in Fukushima, experts had not predicted tsunami waves as high as 10 meters, or the speed.
Power cables have now been reconnected to reactors 1 and 2.

Monday (Japan Time)
Power is close to being restored to the overheating reactors.
Radiation has been detected in milk and spinach from Fukushima.
Taiwan has also detected radioactivity in a batch of imported Japanese fava beans.
The Japanese government has signaled the Fukushima nuclear plant may be scrapped.
Number 3 reactor stabilized after fire trucks doused it for hours with hundreds of tonnes of water.
TEPCO said it may take days to restore power to the number 3 and number 4 reactors. Power is needed to reactivate water pumps to cool fuel rods in reactors.
If the pumps cannot be restarted, drastic measures may be required such as burying the plant in sand and concrete, as happened at Chernobyl in 1986, though experts warn that could take many months.

Friday (Japan Time)
Engineers at Japan’s stricken Fukushima nuclear power plant have managed to lay a cable to reactor 2, the UN’s nuclear watchdog reports.
Water from water cannons has managed to reach a reactor pool.
TEPCO is laying new power cables into the power plant to try and reactivate cooling system.
30 tons of water has been sprayed at the reactors. TEPCO thinks this has been somewhat successful.
8:30am Japan Time
Steam has been rising from 2, 3 and 4 reactors. It is believed water is evaporating inside them.
It is believed water from water cannons did reach the spent fuel rods pool, which is the most important.
Radioactivity at the Fukushima plant has been decreasing, after the water cannon operation.
Press briefing by Japan Nuclear Safety Agency (9:25am).
The spent fuel rods pool water level in reactor 4 has almost been recovered. The rods are not exposed. It is believed the water temperature is about 40-50C.
Power lines to the plant are being repaired. They were damaged in the earthquake. The plan is to connect reactor number 1 and 2. This will be done as fast as possible.
Sea water is still being injected into reactor 1.
139 firefighters are preparing to spray more water onto the reactors. Some engines have the capability to spray over 20 meters in high.
12:40pm Japan Time
Reactors 3 and 4 both have spent nuclear fuel rod pools, which will be sprayed with water from the ground, as they are of primary concern at this time.
Some of the fire trucks can spray up to 5 tons of water per minute.
Helicopters will not be used to dump water on Friday.

Thursday (Japan Time)
9:30am Japan Time
Winds are blowing to the southeast out to sea, but are expected to turn to the south later.
Some governments have cautioned citizens not to travel to Japan for the time being.
There is more snow in the forecast for northern Japan.
There has been steam rising from numbers 2, 3 and 4 reactors.
Water cannons have arrived at the plant.
If the situation continues, fuel rods could be exposed to the air and expose radiation to the air.
Reactors 5 and 6 are continuing to heat up.
The priority is to recover water levels in the reactor suppression pools.
Efforts to spray water on a storage pool is soon to get underway.
9:50am Japan Time
Water has just been dumped by helicopter on reactor 3.
There are 2 helicopters in action.
A second dropping of water has taken place. (9:52am)
Aerial dumping of water is continuing. Helicopters must remain static for a time to dump water, over high radiation. This is very dangerous.
Water cannons are being positioned on the ground to spray when the choppers have finished.
The helicopters are capable of dumping 7.5 tons of water each.
Helicopters are dumping sea water.
There are lead plates on the bottom of the helicopters to protect the crew from radiation.
Water was dumped 4 times by 2 helicopters, on number 3 and 4 reactors.
The water dumping on the reactors was carried out by Japan Maritime Self Defense Forces.
The storage pools in the reactors are/should be 15 meters deep to cover the fuel rods.
11:28am Japan Time
Press conference by Japan Defense Minister.
Radiation levels were too high yesterday to carry out water dumping. It could not be delayed any further, so it was carried out today.
The impact of the water dumping is not yet known. Investigations are taking place.
12:10pm Japan Time
Press conference by TEPCO.
There is water in reactor pool 4 and steam was rising from 3, so they decided to concentrate on reactor 3 with water.
TEPCO says it does not know how much water is left in the reactor storage pools.
TEPCO guesses there is hardly any water left in the storage pool of reactor 3. There is still water in reactor 4, seen from helicopter.
There is hardly any change in radiation levels since the helicopter water drop.
Water cannon operations are to start shortly. Crew are putting on radiation gear.
7:30pm Japan Time
The US govt has told any of its citizens within 80km of the Fukushima reactors to get clear of the area.
Attempts are being made to restore power to the cooling system to cool down reactors.
The Australian government is advising its citizens to head south from Fukushima if in the area, and to consider leaving the country.
Japan citizens are being called upon to conserve energy wherever possible.
Britons who live and work in Tokyo are being advised by the govt to consider leaving for the time being as well.
7:48pm Japan Time
Emergency crews temporarily withdrew a water cannon from the Fukushima Daiichi nuclear complex because of high radiation levels.
TEPCO is attempting to restore high voltage power to the plant to help cool the reactors.
8:07pm Japan Time
Water is now being sprayed into the no 3 reactor.

Wednesday (Japan Time)
10:00am Japan time
Smoke is billowing from the Fukushima Daiichi plant.
The Tokyo Power Company has said another fire occurred earlier on Wednesday at the plant.
The company is investigating the possibility of spraying boron from a helicopter to slow nuclear fission.
11:15am Japan time
Official press conference:
A request was made to save fuel, for the national interest. Disaster hit areas will be prioritized.
No 3 reactor is emitting white smoke. The cause is not yet known and is being investigated.
Radiation levels are fluctuating hour by hour but poses no threat.
The escape of radioactive vapor is the most likely cause of the fluctuating radioactivity levels, but this is not confirmed.
There has been no report of another explosion.
It is assumed (not confirmed) that radioactive vapor is escaping from the broken containment vessel.
The temperatures are rising in number 5 and 6 reactors. Efforts are being made to cool them down.
Many countries have offered help and support for the nuclear situation. Authorities are considering this.
At 10am the radiation level rose to a millisievert level at the plant, but fell to microsievert levels again.
12:10pm Japan time
The radiation level got to 2-3 millisievert but has declined, as earlier reported.
They still don’t no the cause of the white smoke.
TEPCO has said reactor 2 may be the cause of the radiation rise.
2:15pm Japan time
The government has raised the radiation limit nuclear plant workers are allowed to carry out work in Japan, which is still below the international limit.
Wind is tending towards the south, from Fukushima.
3:00pm Japan time
It is been assumed the smoke rising from the number 3 nuclear reactor is radioactive.
8:00pm Japan time
Data shows that cause of the nuclear plant issues was tsunami waves that inundated the plant and knocked out the emergency cooling system.
There are problems with all 6 Fukushima reactors. Reactors 5 and 6 have been heating up.
9:00pm Japan Time
An operation to drop water from helicopter onto reactor number 3 to cool it down was called off, as radioactivity was too high to the helicopter crew to sustain. The roof of the reactor is destroyed.
Water cannons are being considered as an option to cool down reactor 3 tomorrow.
The most serious problem hampering efforts is very high levels of radiation at the plant.
Water temperatures in the container vessel pools in the reactors are thought to be very high.
It is a very difficult and stressful process for workers attempting to work at the reactors. They are only able to work for short periods, as radiation is very high and fluctuating. They have to evacuate as levels rise.
The level of radiation workers are allowed to be exposed to has been increased to 250 millisieverts by the government for this situation.
Workers can only stay in such conditions for a very short time without serious health implications.
The helicopters are capable of dumping 7.5 tonnes of water each.

Tuesday (Japan Time)
There has been a third explosion at a nuclear reactor in Fukushima Japan.
Info is coming out periodically via y press conference in Japan.
The explosion “may have damaged the inner steel containment vessel of the No. 2 reactor.” Workers have been evacuated.
A fuel rod in the no. 2 reactor has been exposed.
The company that owns the reactor said it cannot rule out that the fuel rods may be melting.
“This is a very serious situation”. “There is a possibility of radiation leaking to the outside.”
The sound (explosive sound) was heard around 6:14am local Japan time, around the area of the suppression pool at the bottom – Tokyo electric. There could have been some fault in the suppression pool.
Pressure in the containment vessel has gone down, meaning there might be cracks in the vessel.
About half the length of the fuel rods has been exposed.
The suppression pool is one of the cooling systems for the reactor.
Right after the third explosion, higher levels of radiation were detected, but they become lower again soon after.
The valve to vent steam from the reactor had closed and they were trying to open it when the explosion occurred.
Investigations are underway to find out why radiation levels are fluctuating so much at the plant.
The steel containment vessel is the last line of defense against radiation leaking out of the reactor.
Winds are blowing southward. This is expected to continue until Tuesday, Japan time.
The Japanese prime minister has said radiation has spread from the reactors.
A 20 kilometer exclusion zone has been set up around the nuclear power plant.
He says every effort is being made for radiation not to be spread.
Nuclear plant workers are putting themselves in a dangerous situation to try and cool the reactors.
The prime minister has called for citizens to remain calm.
The prime minister did not mention the latest reactor explosion, preferring to talk about the overall situation. It contains spent nuclear fuel.
The utmost effort is being made to put out the fire and cool the reactor.
In the number 2 reactor a hole was observed.
Water injection is continuing into all three reactors. This is said to be going smoothly, so it is believed they are being cooled successfully at this time.
Inside the 20km zone around the reactor, people still there are being asked to stay inside and not used ventilation.
The fire in reactor 4 is “an ordinary fire”. The reactor is emitting heat. The fire should not ignite hazardous material.
We are asking people within 30km from the plant to stay indoors.
11:30am local Japan time now.
The possibility of more radioactivity being released into the environment is increasing.
In the exclusion zone, If possible stay inside a concrete building and do not used air conditioning. Do not go outside.
Firefighters at the number 4 reactor are wearing protective clothing as the radiation is very high.
The US aircraft carrier Ronald Reagan has been relocated, away from the nuclear plant area. Some crew on a helicopter monitoring the plant were exposed to radiation, but not to a very dangerous level.
Kyodo News is now reporting a hydrogen explosion at number 4 reactor. (11:53am).
Kyodo News is reporting that number 4 reactor 4 fire now put out: Tokyo Electric (12:04).
Fuel rods were exposed for up to 6 hours overnight.
