@Edano Old data says 20th. There was something out in news articles in recent days mentioning noticeable pressure drops on the 16th. They were not fully clear if they meant RPV only or outer containment also and if the drop was down to atmosphere on the 16th.

@Nancy : very good. this seems more plausible. this may be the week of truth.

@Ian I may have it. Let me see if my website access is back online

@all Good Morning...Good Evening...Hello

hi Smoss

@dean March 12 15:36 Japan time

wanted data based time but the 15:36will work
isn't it in the bcr doc?

Related to the "what happened on the 16th with pressure" I found this. Doesn't answer the question but gives some good data related to it. Also sounds like the smoke shows. "Unit 3(Shut down)
-Reactor has been shut down. However, the explosive sound and white smoke
were confirmed at 11:01am Mar 14th. It was assumed to be hydrogen
explosion.
-At 8:30am on March 16th, fog like steam was confirmed arising from the
reactor building.
-At approximately 6:15 am on March 17th the pressure of the Suppression
Chamber has temporarily increased. We were preparing to implement a
measurement to reduce the pressure of the reactor containment vessel
(partial discharge of air containing radioactive material to outside) in
order to fully secure safety. However, at present, it is not a situation
to take a measure immediately to discharge air containing radioactive
material to outside now. We will continue to monitor the status of the
pressure of the reactor containment vessel.
-At approximately 4:00 pm, March 21st, light gray smoke was confirmed
arising from the floor roof of the Unit 3 building. On March 22nd, the
color of smoke changed to somewhat white and it is slowly dissipating.
-At approximately 10:45 pm on March 22nd, the light in the main control
room was turned on.
-At around 4:20 pm on March 23rd, our staff confirmed light black smoke
belching from the Unit 3 building. At approximately 11:30 pm on March
23rd and 4:50 am on March 24th, our employee found no signs of smoke.
-We have been injecting sea water into the reactor pressure vessel."

@Elaine, is that new or did we just finally find it? Photos are March 23rd

@Edano: found this related to the 16th. I don't know what the pressure related to the previous pressure readings were. "# At 9:55AM on March 16, the pressure inside the reactor core was measured at 0.088 MPa. The water level inside the reactor core was measured at 1.9 meters below the top of the fuel rods.
# At 11:32AM on March 16, the Japanese government announced that the possibility of significant damage to the primary containment vessel was low."

@elainekirk is this all new data dump stuff or things they had buried somewhere?

The NYT article RadioGuy posted is a good read. Seems to outline much of the background Elaine found on Fuku.

Tepco Rethinking Plan For Cooling Reactors

TOKYO (Nikkei)--In light of indications that damage to the No. 1 reactor at the Fukushima Daiichi nuclear power plant is worse than expected, Tokyo Electric Power Co. (9501) is expected to take a fresh approach to cooling down the fuel rods by installing equipment to circulate water that has been pumped inside.

The utility is scheduled to release on Tuesday a revised road map for bringing the reactors damaged by the March 11 earthquake and tsunami under control.

The amount of water being pumped in has already been increased to 10 tons per hour. But the water that leaks out and builds up inside the reactor building is a concern.

"Heat exchangers and equipment for removing radioactive substances are necessary for pumping in and circulating water," said Takashi Sawada, vice president of the Atomic Energy Society of Japan. "Unless there is removal (of radioactive substances), the contamination will spread and the ensuing work will become impossible to perform."

If the fuel rods have breached the pressure vessel and reached the bottom of the containment vessel, installing the equipment will become more difficult. Bringing the situation under control could take longer than the initially envisioned six to nine months.

Some have suggested pinpointing areas of the containment vessel that have sustained damage and making repairs with cement or other materials, but the radiation is so strong that workers cannot get close. Another proposal calls for circulating the contaminated water that has gathered in the basement, but this is also not possible because workers cannot enter the area.

Japan: U.S. Agency to Stop Monitoring Nuclear Plant

"The United States Nuclear Regulatory Commission said on Monday that its 24-hour operations center had stopped monitoring the nuclear reactors at the Fukushima Daiichi plant because the situation there had improved. “The conditions at the Japanese reactors are slowly stabilizing,” said William Borchardt, the agency’s chief staff official. “As conditions have continued to improve and the Japanese continue to implement their recovery plan, the N.R.C. has determined that it is time to adjust our response,” he said.

@radioguy WOW, guess, they sleep with the EPA !!

@elainekirk Good Truth-o-meter!
