Workers enter No.3 reactor
Workers have entered the Number 3 reactor building at the Fukushima Daiichi nuclear plant for the first time since a hydrogen explosion 3 days after the March 11th quake and tsunami.
Tokyo Electric Power Company says 2 workers in protective suits and carrying air tanks went inside for about 10 minutes from 4:30 PM Wednesday to check radiation levels.
TEPCO says the workers measured radiation of 160 to 170 millisieverts per hour around the door of the containment vessel.
The utility says it would be difficult to start work on injecting nitrogen gas needed to prevent a hydrogen blast into the containment vessel under such high radiation levels.
The utility said the 2 workers were exposed to radiation of 2 to 3 millisieverts.
TEPCO has now been able to send workers into all 3 reactors that were operating at the time of the quake and tsunami. Workers entered the Number 1 reactor building on May 5th and the Number 2 reactor on Wednesday morning.
TEPCO is rushing to make the reactor buildings safe enough for workers to go inside and proceed with the plans outlined in its roadmap to stabilize the reactors.
This includes installing new cooling systems to circulate water leaked from containment vessels back into the reactors and the nitrogen injections.

@Angie exactly what happened last time - that is why I didn't dare to restart my computer (haven't yet). Well, I talked to De Geer and I am only afraid that I misunderstood him (not easy stuff this), but if I didn't then I trust him that the CTBTO data is reassuring for all you in the US - if it isn't and all governments around the world are hiding that there is harmful levels of eg Plutonium in the US then it will of course not be possible to hide in the long run. The music I heard now was the same as last time in the beginning of this blog (and somehting weird briefly appeared on the screen (Hi I am ... didn't catch the rest). Anyway I think it is highly likely that it has to do with using this blog so I am out of here (related to a person using this blog - not a government). I thank you all for the fantastic work you have done and it has contributed to an increased interest in these questions (probably for the rest of my life) and convinced me that nuclear energy is much too dangerous for us humans. I am also questioning a lot of 'known facts' about the dangers of radiation. I found an interesting study of cancer incidence in regions in Sweden that got a lot of downfall from Chernobyl where Tondel et al found much higher incidences, but this was met with resistance. bit.ly Good luck to you all and again thank you!by Jill in Sweden edited by Angie 5/19/2011 7:12:12 AM- 5 tons of seawater may have entered Hamaoka nuclear reactor
SHIZUOKA, Japan, May 19, Kyodo
Around five tons of seawater may have entered one of the reactors at the Hamaoka nuclear power plant in Shizuoka Prefecture along with about 400 tons of seawater found in its steam condenser when work was under way Sunday to put the reactor into a state of ''cold shutdown,'' Chubu Electric Power Co., the plant operator, said Thursday.
The reactor will not be decommissioned because the utility will dilute and desalinate the seawater in an effort to prevent any corrosion inside the reactor, the company said.
Seawater might have entered from damaged piping inside the condenser, which cools steam from the turbine and turns it into water.

Funny that you used the that term.

- New cooling systems to be installed at fuel pools
The operator of the damaged Fukushima nuclear power plant is likely to start operating a new system within 2 weeks to cool spent fuel in reactor Number 2.
Tokyo Electric Power Company says it is preparing to install cooling systems in 4 of the 6 reactor buildings, 3 months earlier than initially planned.
TEPCO says it is laying power cables for a cooling system for Number 2 reactor's spent fuel pool. A heat exchanger will be brought into the facility early next week to start operating the cooling system by the end of this month.
Workers entered the Number 2 reactor building on Wednesday for the first time since a hydrogen explosion on March 15th. They tried to check radiation levels but left the building after 14 minutes because it was filled with steam, making further work impossible.
The utility says the vapor appears to be coming from the damaged suppression chamber as well as from the fuel pool itself.
Senior TEPCO official Junichi Matsumoto says he believes cooling the spent fuel pool will help reduce steam inside the reactor.
TEPCO reports more than 90 percent humidity inside the Number 2 reactor building. Matsumoto says the building's roof is intact, making it more prone to filling with steam. Number 1 and 3 reactor buildings are exposed to the air because hydrogen explosions blew off their roofs and walls.

Morning @all. A friend of mine who was an engineer working with UK nuclear plants summed up the lack of preparedness v. succinctly - "old reactors, didn't want to spend the money"by hudebnik 5/19/2011 7:56:31 AM- That and the reinforcements (which they must have know were needed or they would not have built them)at Diani will make TEPCO a dead company.by Ralph Unger 5/19/2011 7:56:45 AM

- Just linking some stuff I put on the wiki a couple of days ago, as Tepco still haven't admitted the true status of #2 and #3 - these graphs of reactor water level and reactor show clearly I think that all the RPVs failed and thus meltdowns occurred in the early day. level pr data 1u-j pdf
