Torrential rains in my neighborhood

Something about the high winds blowing in the background, and the seasons changing so suddenly made me just slump over in my chair around noon, listening the sounds of nature outside.

Finally I dragged myself out of my slumber and shook myself awake, figuring I ought to do some grocery shopping. But… what was that sound? I looked outside and saw this (click to see video – expand to full screen for best effect). Huge, torrential, sweeping rains. An umbrella won’t help here.

Well, I hope anybody who is out and about are managing to find a snug, dry place to hole up until this passes by.

Spring winds

Since yesterday there have been extremely strong, balmy winds blowing through Tokyo. They were strong enough to keep you awake at night, and are still swirling around and howling outside.

This happens every year, and seems to mark the true beginning of spring in Japan. So except for pollen sufferers, most people seem really happy that winter is finally over.

I am looking forward to a very low electric bill next month!

I’m sorry, I wasn’t listening

Obamacare, the mandate, the Commerce clause and the single-payer option

I agree with Eugene Robinson’s column. If Obamacare is ruled unconstitutional the only real alternative is a single-payer system. That is clearly constitutional (see Medicare).

But I hope the argument which was made at the end of the 2nd day of Supreme Court deliberations, that health insurance is inseparable from health care and everybody does use health care, is sufficient to convince the course that the insurance mandate falls well within the Commerce clause.

Reactor 2 radiation too high for access

73 sieverts laid to low water; level will even cripple robots

Radiation inside the reactor 2 containment vessel at the Fukushima No. 1 nuclear plant has reached a lethal 73 sieverts per hour and any attempt to send robots in to accurately gauge the situation will require them to have greater resistance than currently available, experts said Wednesday.

Exposure to 73 sieverts for a minute would cause nausea and seven minutes would cause death within a month, Tokyo Electric Power Co. said.

The experts said the high radiation level is due to the shallow level of coolant water — 60 cm — in the containment vessel, which Tepco said in January was believed to be 4 meters deep. Tepco has only peeked inside the reactor 2 containment vessel. It has few clues as to the status of reactors 1 and 3, which also suffered meltdowns, because there is no access to their insides.

The utility said the radiation level in the reactor 2 containment vessel is too high for robots, endoscopes and other devices to function properly.

Spokesman Junichi Matsumoto said it will be necessary to develop devices resistant to high radiation.

High radiation can damage the circuitry of computer chips and degrade camera-captured images.

For example, a series of Quince tracked robots designed to gather data inside reactors can properly function for only two or three hours during exposure to 73 sieverts, said Eiji Koyanagi, chief developer and vice director of the Future Robotics Technology Center of Chiba Institute of Technology.

That is unlikely to be enough for them to move around and collect video data and water samples, reactor experts said.

“Two or three hours would be too short. At least five or six hours would be necessary,” said Tsuyoshi Misawa, a reactor physics and engineering professor at Kyoto University’s Research Reactor Institute.

The high radiation level can be explained by the low water level. Water acts to block radiation.

“The shallowness of the water level is a surprise . . . the radiation level is awfully high,” Misawa said.

While the water temperature is considered in a safe zone at about 50 degrees, it is unknown if the melted fuel is fully submerged, but Tepco said in November that computer simulations suggested the height of the melted fuel in reactor 2’s containment vessel is probably 20 to 40 cm, Tepco spokeswoman Ai Tanaka said.

Tepco has inserted an endoscope and a radiation meter, but not a robot, in the containment vessel. It is way too early to know how long Tepco will need to operate robots in the vessel because it is unknown what the devices will have to do, Tanaka said.

A Quince was exposed to radiation of 20 sieverts per hour for a total of 10 hours, and the device worked fine, Koyanagi said. If the team conducts further experiments, it may find out the robot can resist even more radiation, he added.

According to experts, even though high radiation in the containment vessel means additional trouble, it is not expected to further delay the decommissioning the three crippled reactors, a process Tepco said will take 40 years.

The experts noted, however, that removing the melted nuclear fuel from the bottom of the containment vessels will be extremely difficult.

Tepco inserted a radiation meter into the containment vessel of reactor 2 Tuesday for the first time, measuring atmospheric radiation levels at several points inside the vessel. The readings logged 31.1 and 72.9 sieverts per hour.

Tepco has not been able to gauge the water depths and radiation levels of the containment vessels for reactors 1 and 3, as, unlike unit 2, there is no access.

Mon’s unusual egg laying activity

I tried leaving Mon’s eggs in the nest this time to see if it would discourage her from laying eggs each month.

What she has been doing this week, though, is every day she’ll throw an old egg out of her nest and lay a new one, leaving 6 at any time.
