Reactor4 still remains frail for Tsunami

Tepco emphasizes they reinforced reactor4 against earthquake resistance, but actual Fukushima worker Happy11311 comments it’s only for the SFP4 and Tsunami guard is still in the temporary state.

Good morning, Mr. Happy11311. Yesterday, news reported Tepco built pillar under SFP4, but does it have base isolation system of earthquake ? and there was heavy equipment on the top floor but is Tepco reinforcing the entire building and Tsunami guard ?
<End>

Good evening. The pillar is not for seismic isolation building, just for the bottom of SFP4. (didn’t answer the question about base isolation system of earthquake) Now Tepco is not doing anything to reinforce the building. Tsunami guard remains the temporary state as well.
<End>
From the photos of reactor 4 which Tepco released on 5/28/2012, the Tsunami guard is only the debris collected in nets.

Tepco is going to attach a freezing machine to water circulation system

Following up this article..Tepco plans to increase water injection of reactor 3
Tepco is going to increase the amount of water to inject only for reactor 3.
It is because the coolant water is heated for summer, but it suggests the situation of reactor 3 is more severe than other 2 reactors.

In the daily press conference of 5/28/2012, Tepco announced that they are going to attach a freezing machine to the water circulation system.
Specifically, it will be attached to the facility called buffer tank located after desalination equipment and cesium removal system.

Tepco estimates they can keep the temperature of each reactor under 65 ℃, which is 15 ℃ lower than the safety limit regulated by Nuclear and Industrial Safety Agency.
However, there was no explanation that how much the temperature would be if they don’t rely on the freezing machine.

Tepco is planning the first endoscope operation to reactor1 announced in the daily press conference on 5/28/2012.
They are starting to prepare it by mid August, and finishing the operation from the end of August to September.
They are starting to prepare it by mid August, and finishing the operation from the end of August to September.
The endoscope will be inserted from the through hole “X-100B”, located on the first floor.
Because it’s 4.5m high from the floor, they will build a trestle to operate.

The purpose is to check the atmospheric temperature, dose, temperature of water and the water level.
They also plan to take the sample of water inside of the PCV.
However, they will not be able to see the nuclear fuel directly because it’s outside of the pedestal. Tepco assumes the melted fuel is inside of the pedestal.

Tepco also assumes, the nuclear fuel is “cold” to remain in the PCV. It has been in coolant water for longer than one year, water‐soluble nuclide might be captured in the sampling water.
However, they admit it’s just their assumption that the nuclear fuel remains within pedestal. Still it’s not known where/how the fuel is.

Shin-ichi Sano, Author: The world had not choice but to pay attention.People have said that we must gather expertises from around the world in order to solve the current problem.Regarding Fukushima, this has to happen, don’t you think?Indeed. As you say, there is no time for silly arguments.
