Videos of SFP in reactor3
Posted by Mochizuki on September 24th, 2012 · No Comments
On 9/22/2012, Tepco dropped 7m of the steel truss to SFP3. (cf. 7m and 470kg of steel frame dropped into the SFP of reactor3, “566 fuel assemblies are in the pool”)
According to Tepco’s press release, which they didn’t release in English, it was an mis-operation of the oil pressure fork.
Tepco states no significant change in radiation level of atmosphere and pool water, and also the temperature were observed, but the data showed they measured extremely high level of radiation (173.0 mSv/h) at 9:28 of 9/21/2012. It was measured at 2m above from the surface of the pool before the accident.
These are the videos of SFP3 taken by Tepco on 9/22/2012.
Tritium leakage from reactor 5 and 6
Posted by Mochizuki on September 22nd, 2012 · No Comments
On 9/21/2012, Tepco released the nuclear analysis result of radioactive materials in the sea water.
The samples were taken on 4/16 and 5/14, so their release is 5 ~ 4 months behind.
The result shows 3.8 ~ 6.0 Bq/L of tritium leakage from around reactor 5 and 6 (North of Unit 5-6 Discharge Channel).
Tepco evaluates it is from the Fukushima accident. From April to May, the tritium amount increased.

>> UPDATE: Japan TV: "Grave mistake" that crane knocked beam into No. 3 fuel pool -- Checking for fuel damage with camera soon (VIDEO) <<
According to the Yomiuri Newspaper, up at FD1 reactor #3, a steel beam, 470kg (30cmX20cmX7m), fell into the spent fuel pool. [...]
Jiji Tsushin report from Sept. 22, 2012 translated by EXSKF:
TEPCO announced on September 22 that a steel frame weighing about 470 kilograms dropped into the Spent Fuel Pool of Reactor 3 during the debris removal operation of the Reactor 3 building [...] So far, there is no major increase in radiation levels nearby, TEPCO says.According to TEPCO, the accident happened at 11:05AM on September 22 when [EXSKF: the crane operator] tried to grab a piece of debris, an H steel lying next to the Spent Fuel Pool on the 5th floor of Reactor 3 building and failed. The H steel slid into the Spent Fuel Pool.
A huge metal beam was dropped into a spent fuel pond at the Fukushima Daiichi nuclear plant. Workers were trying to extract cement wreckage [...] The crane boom accidentally pushed a metal beam into the pool from its casing, reports ITAR-TASS news agency. [Tepco] says the metal construction, 7.3 meters [~25 feet] in length and weighing 470kg, did not cause any breach in the cooling system, but could complicate further retrieve of spent nuclear rods.[...]Reports say it was accidentally dislodged from its place by a crane.Fortunately, no one was hurt in the incident. It is not yet clear whether any of the spent rods has been broken.
