July--2011-Timeline of the Fukushima Daiichi Nuclear Disaster

Sunday, 3 July--2011-Timeline of the Fukushima Daiichi Nuclear Disaster 
The water decontamination (Fukushima Neclear Power Plant )  and water recycling systems are now both functional. 100% recycled water is now used for reactor cooling, and no additional volume of contaminated water is being generated.

Radioactive caesium-137 is found in Tokyo's tap water for the first time since April. Radioactive caesium from Fukushima was expected to enter the Japanese seafood supply, and was projected to reach the US West Coast in 5 years .

The Japanese Nuclear Safety Commission publishes a report dated June 11, 1993, (Heisei 5) whose title literally translates to The event of entire alternating current station blackout on the nuclear power plant  conducted by a working group. This reports the results of an evaluation of the regulations to prevent and handle an occurrence of the full loss of alternating current (Station Blackout or SBO) in nuclear power plants in Japan and other countries. It concludes that further discussion is needed on methods to avoid or recover from such accidents. It also reports that the probability of an SBO in Japan is lower than in other countries.

The number of people actively working at the Fukushima Daiichi nuclear plant is about 3,000. NISA orders TEPCO to boost the number of safety managers to support this large number of workers. The water decontamination systems continue to be plagued by leaks and filter problems. Over the last week they had been operating at an average of 73% capacity, below the target of 90% which is required to meet the current timetable.

In a joint assessment the Japanese government and TEPCO say they have completed the first step of a 3-month plan outlined in mid-April for a complete cold shutdown. Reactors 1, 2 and 3 have been cooled down to a stable level and nitrogen has been injected into their containment vessels to prevent hydrogen explosions; however, the assessment admits that contaminated water has leaked out of storage tanks, and that water level settings at its water purification facilities were incorrect.
