TEPCO: Nuclear fuel pool cooled to stable level

The operator of the crippled Fukushima Daiichi nuclear plant has reported progress in its work to stabilize the facility's spent fuel rods.

Tokyo Electric Power Company says the cooling system that began operating at the No.3 reactor on Thursday has brought the temperature of the nuclear fuel storage pool of the reactor to just below 40 degrees Celsius from the previous level of 62 degrees.

TEPCO says the temperature of the pool was 39.9 degrees as of 5 AM on Saturday.

As cooling has progressed faster than initially expected, TEPCO says the temperature will likely stabilize at around 30 degrees in a few days. The temperature of the spent fuel pool of the No.2 reactor has already declined to that level. As for the No.1 and No.4 reactors, the utility plans to begin operating cooling systems by the end of this month. Until then, the company needs to inject cooling water on a regular basis.

TEPCO is concerned about possible difficulty in installing the cooling system at the No.4 reactor. A hydrogen explosion in March damaged piping necessary for the system and debris left there is hampering construction work.

The company says there may be a delay in its installation plan.

The temperature is rather high for comfortable bathing, at constant 85 degrees Celsius (185 degrees Fahrenheit).

One can have a nice boiled egg at that temperature.

Time will tell.

Hey, how many people died at Fukushima? Still 0.

Dozens of workers from Fukushima nuclear plant 'cannot be found'

[BenKenobi]

Absence of evidence!= evidence of absence.

“Nine workers at the plant, which is months away from a cold shutdown, have exceeded the declared limit of 250 millisieverts of radiation and the government is anxious that the missing workers be checked.”

250 millisieverts is 1/4th of a sievert. Over the course of a day, a sievert would be a fatal dose.

250 millisieverts is only going to prevent nausea.

[BenKenobi]

sorry, provoke nausea.

[justa-hairyape]

You cannot make a blanket statement that no workers at Fukushima have died, when everyone in Japan admits dozens of these workers cannot even be found. And you cannot make blanket statements about radiation exposure when dozens of these workers cannot now be found. But you know that. And your game is always just to lie to cover up specific problems. In this case you are trying to cover up the fact that dozens of Fukushima workers cannot now be found.

Technically they should be listed as MIA. Not KIA, but MIA. At any rate, anyone who has watched videos of both explosions knows dozens were killed by the explosions alone. Otherwise, you believe in miracles.

[BenKenobi]

Dead means dead, not missing. Deaths have to be confirmed.

As for the dosage .25 sieverts in one exposure is insufficient to cause death.

.25 sieverts over the course of weeks working at the plant? Probably not enough to make someone sick, but it’s possible. The reason that the Japanese government made .25 sieverts the limit is that above the limit is where the negative effects of radiation sickness begins to appear. SO those who exceeded this could have gotten sick.
