Water filters at Fukushima still not working
The operator of the Fukushima Daiichi nuclear power plant is still struggling with a malfunctioning water-decontaminator---the key to dealing with highly-radioactive water accumulating at the site.

The new water decontaminating system was shut down only 5 hours after it went into operation on Friday.

Tokyo Electric Power Company says an irregular flow of the water in the system could have hampered the system from working properly, causing it to malfunction.

The utility says it discovered on Wednesday that a US-made device in the system only succeeded in lowering the concentration of radioactive cesium in the water to one percent of the previous amount, instead of 0.1 percent as initially expected.

The device has 6 absorbent chambers lined up in a row.

The utility says radioactive readings in the lower chambers surged to 15 millisieverts per hour on Wednesday from 3 millisieverts per hour on Tuesday.

This occurred even though dosages in the lower chambers should have remained low, compared with those higher up where most of the filtering was supposed to have occurred.

It says this suggests that the problem could have been caused by the uneven flow of water through the chambers.

It says it will continue to try and identify the cause of the problem so that it can begin operating the system as soon as possible before the water begins to overflow from the facilities, which are almost full.

@all Therefore, the time periods important to the fresh MOX fuel compositions are the total time from discharge of the uranium fuel (used to manufacture the MOX) to the loading date of the MOX fuel (effect on the Pu vector), and the time from reprocessing to the loading date (effect on the Am 241 content).

@Lilly Must be..biggest crane I think I've ever seen....or one of, anyway.

@Lilly There's a smaller crane on the side of 1 right now.. When it's close to the building it kind of blends in.

@Lilly I find that so tragic. Given the weather and deplorable conditions it's going to be incredibly difficult work for them.

Sorry for my bad English, I'm half asleep. Take care and keep up the good work. Got to get some rest.

@all 3.2.3 Americium-241 Content
Americium-241 exists in unirradiated MOX fuel as a result of β- decay of 241Pu after the
plutonium is separated from the irradiated uranium fuel. The 241Pu decays with a half life of
14.4 years. Consequently, the amount of 241Am increases rapidly within several years of
reprocessing, and can cause a significant radiation hazard from the neutron and gamma rays
associated with the decay of 241Am. The dose rate increases about a factor of two every 120 days
of storage for the first several years caused by 241Am in-growth at a rate of 0.48% of the 241Pu
concentration per year.8 Therefore, there is considerable incentive to limit the amount of storage
time of reprocessed plutonium or fabricated MOX fuel prior to reactor loading.

OK first video is amzing. Second video backs up the plume. If two videos ever had to go viral maybe I'm bias but these are it. Please post to any blogs you know.
