NHK: Wastewater filters still working below target
A system installed to recycle radioactive wastewater at Fukushima Daiichi nuclear plant continues to work below its target capacity, due to a series of filter problems.
The plant's operator, Tokyo Electric Power Company, started running the system on June 27th to decontaminate radioactive wastewater pooled in reactor buildings, and send it back into the reactors as coolant.
The utility aims to have the system's decontaminating device working at 80 percent capacity.
However, the operating rate for the first week was below target. During its second week, the system was only operating at 73 percent capacity....
...The decontaminating device was halted again on Wednesday afternoon because of leaks.
The utility considers the system to be critical in cooling the reactors and bringing them under control in line with the timetable it has set.

MAJIA HERE: The problem is, according to Arnie Gunderson, that there is simply SO MUCH HIGHLY RADIOACTIVE WATER that the filters are insufficiently capable of filtering it. Arnie said the filters would become so radioactive that they could not be handled.
NHK: New cooling devices set for Fukushima fuel pools
The operator of the troubled Fukushima Daiichi nuclear plant is to set up two more cooling systems for reactors' spent fuel storage pools.
The planned devices are to start operating in late July at the No. 4 reactor pool and in early August at the No. 1 pool.
Spent fuel rods are currently kept in the storage pools of each of the 4 reactor buildings. The No. 2 and No. 3 reactor buildings already have cooling systems and water temperatures in these pools is at the normal level of below 40 degrees Celsius....

MAJIA HERE: I still do not believe that there is a spent fuel pool #3 anymore based on the state of building #3, but I'm no expert and that is simply my uninformed opinion.
Notice that there is no word of the proposed nitrogen injections at unit #3.
These injections keep being delayed and delayed.
However, TEPCO must have done something to unit #3 because I no longer see flames and really massive emissions at that unit (thankfully). I hope I'm not simply missing them since I've been sleeping so late....
