Outrage as Japan lifts radiation limit for kids

Outraged parents have held a rowdy demonstration outside Japan's education ministry in Tokyo to protest against the government's decision to weaken nuclear safety standards in schools.
Under new guidelines, Japanese children are allowed to be exposed to 20 times more radiation than was previously permissible.
The new regulation means children can now be exposed to as much radiation as a German nuclear worker.
The government argues the change is essential to keeping schools open in the Fukushima region…

Temperature readings indicate melted cores are being cooled

…"Right now, the most important thing for reactors 1 through 3 is to continue cooling them," Kudo said. "I will not say that there is no need to worry, but I don't think the situation will deteriorate as long as they continue to be cooled."
Tepco conducted the computer simulation for units 2 and 3 after discovering last week that the water level indicator for the pressure vessel in reactor No. 1 was not working properly, and that coolant water had not fully covered the fuel rods.
After fixing the indicators, the utility found the water level was much lower than believed, and that the rods were fully exposed and likely melted down.
Consequently, Tepco said it began to doubt that the water level indicators for the pressure vessels in reactors 2 and 3 were working…”

The operator of the Fukushima Daiichi nuclear power plant is still unable to determine how long an emergency cooling system at the Number 1 reactor remained off after the March 11 earthquake.
Officials of Tokyo Electric Power Company spoke to reporters on Tuesday about the system, which can function without external sources of power.
Operating records at the plant show that the system turned on automatically 6 minutes after the earthquake, at 2:52 PM, and halted 11 minutes later, at 3:03 PM. The system was back on more than 3 hours later, at 6:18 PM.
TEPCO says that based on hearing from workers, it has confirmed that the system was manually shut down at 3:03 PM. It said this step was made based on a manual, in order to prevent damage to the reactor, because the temperature of the water to cool the No.1 reactor had dropped sharply...

By Quentin McDermott for Four Corners
"...But Dr Goto says the Fukushima crisis shows Japan has not yet learned the lessons of history.
"At Three Mile Island the nuclear fuel melted. Fuel is melting here now," he said.
"We have to design reactors to withstand melting fuel rods. Right now the reactor will break down due to the heat generated by the melting rods."
Dr Goto alleges that in Japan's nuclear industry profits take precedence over safety standards. "No-one says it officially or openly. When setting standards for future earthquakes, the thought is of money - how much is it going to cost?" he said...

Residents in an evacuation area near the troubled Fukushima Daiichi nuclear power plant have started moving their cattle to a neighboring city.
Katsurao village is helping livestock farmers move their animals as it aims to complete the evacuation by the end of May. More than 400 cows are still in the village.
The transfer of about 170 cows from the village to neighboring Tamura City started on Tuesday.
Earlier this month, small amount of radioactive cesium was detected in beef processed from cows carried from Katsurao Village to Aomori Prefecture...
