brb.. meeting with some engineers for tomorrow work.. elsie I will look at that when I get back ..

Nothing new at kyodo, after 8 japan time, life must be good, no problems

@Val UK: if there's no wind, hard to see any difference.

Food for thought... "The readings being retracted are not due to miscalculation. If you will check the tides for the last 24hrs you will see that the initial VERY HIGH reading was @ high tide. The second re-reading was taken @ low tide. This style reactor uses a single cooling loop and appears to have a leak in the turbine room. The tides coming in puts positive pressure in this loop and radiation collects. When the tide goes out it places a vaccume on the system pulling vast amounts out to sea.
Tepco will publish samSeems this ples taken @ low tide from now on it seems."Eric Shidler on March 27, 2011, 4:04 PM www.tKit for whatheoildrum.com

@George Gibb I reposted that comment with links at 4:58

Did anyone catch the interview on NKH a few minutes ago? An expert was commenting on the video (I believe the one linked above) saying that a crane or something had actually fallen over and likely damaged the rods in (I think) R4. Also, some kind of a containment lid blown off. This was new information to me. Could anyone please elaborate/clarify? Thanks.

@Chris: imho if a crane would have fallen in the spent fuel pool it would be in #3. From SPD shots, it seemed to me that we could see the crane above the spent fuel pool of #4 still in place

@ chris- they might be playing it again soon. Was that the interview with the clay models of the damaged reactors?

We haven't had a TV for years, by choice. So that's what we all have in common on this blog....

Ok since even NHK is mentioning "livestation" for their Iphone app, here is the link to the online Streams, that i watch

I'm a bit confused. I see the relationships between rads, rems, sieverts etc. But how does this relate to the amount of radiation present ie curies, becquerels. Specifically, if you remove 1/2 a radioactive puddle of x sv/hr - what results - 1/2 the sv rate since half the energy in decay was removed?

@chris (opinon) I did nt see english version, but I belive the lid you are refering to is the containment lid (not vessel lid) for #4, it is my understanding that they were doing mantaince(probably refueling) and had the contaiment lid off. but do not believe it blew off... if you watch the explosion on #3 the height of the plume and force, I would think #3 suffered trmenous damage to the buiding and mechanical systems, not sure about the contaiment vessel? my guess is the rod pool suffered some damage or/and debrie fill.

@VeenOui That's from 2 days ago but it's still up-to-date.

Monitoring for Increased Levels of Radioactive Material in the US as a Result of the Incident with the Fukushima Nuclear Incident in Japan


Summary: As a result of the incident with the Fukushima nuclear plant in Japan, highly sensitive radiation monitors operated by EPA and others are detecting very low levels of radioactive material in the air in the United States. These levels were expected and consistent with estimated releases from the damaged nuclear reactors and are far below levels of public health concern.

Elevated levels of radioactive material in rainwater have also been expected as a result of the nuclear incident after the events in Japan, since radiation is known to travel in the atmosphere. There have been reports received that several states including Pennsylvania and Massachusetts have detected elevated levels of radiation in rainwater following recent precipitation events.

Background
The numbers of the elevated levels of radioactive material being reported in Massachusetts are 79 picocuries (pCi) per liter (one picocurie is a trillionth of a curie). The numbers reported in Pennsylvania range from 40-100 picocuries per liter. Although these are levels above the background levels historically reported in these areas, they are still about 25 times below the level that would be of concern for use as a sole source of water over a short period of time, even for infants and pregnant or breastfeeding women, who are the most sensitive to radiation.


While short-term elevations such as these do not raise public health concerns – and the levels seen in rainwater are expected to be relatively short in duration – the U.S. EPA has taken steps to increase the level of monitoring of precipitation, drinking water, and other potential exposure routes to continue to verify that.

Given the release of radiation in Japan, it was expected that radiation monitors in this country and elsewhere will detect minute quantities of radiation. These monitors are highly sensitive and can detect amounts of radiation in trillionths of a Curie. We expect environmental monitors will continue to detect low levels of radiation in surface waters due to radioactive material in the air. When it rains or snows, the radioactive material is washed to the ground and onto surface waters.

www.tepco.co.jp looks like something is happening on TEMPCO webcam

@gabe @Diane @everyone Weren't they saying earlier today that the levels were thousands of times below the level of concern, or something like that? Now it's only 25 times? Alarming indeed!

@Tenzing: same shot for more than half an hour. Steam and smoke, likely from #3. Let's wait for next one in ~ 1/4 hour...
