Radiation level spiked in reactor 3. Tepco “The gauge is broken”


One of 4 monitoring gauges in suppression chamber indicated spiking up radiation level in reactor3, which was 47.01 Sv/h at 17:00 6/21/2012.
Other gauges didn’t show any change in radiation level. The furthest one is located at 40m away from the issued indicator.
Tepco states the monitoring gauge was broken because of the humidity, but no fault is found in transmission.
It used to indicate about 0.1 Sv/h. It picked up to 17.59 Sv/h at 5:00AM 6/21/2012.

3号機検出器が故障か=放射線量が急上昇-福島原発
東京電力は21日、福島第1原発3号機の原子炉格納容器下部にある圧力抑制室で、放射線量を測定する検出器の一つで数値が急激に上昇し、毎時約4万7000ミリシーベルトを記録したと発表した。他の検出器はほとんど変化がなく、同社は「検出器の不具合と考えられる」としている。(2012/06/21-20:37)

Slowly Degrading #Fukushima I Nuke Plant: Leak from Reactor 3 Gas Management System, Patched Up With Tape (Temporary I Hope)


Meanwhile in TEPCO land in Fukushima, it's a steady stream of slowly degrading systems and equipment that were hastily assembled last year.

According to TEPCO's plant status report on June 19, 2012 (Japanese only; there is no English version), a TEPCO worker noticed a hissing sound coming from the flexible duct from the Reactor 3 Containment Vessel Gas Management System on June 19 at about 12:19PM. The Gas Management System is located on the 1st floor of the Reactor 3 turbine building. The duct had been damaged for some unknown reason, and TEPCO says the damage has been temporarily patched up with tape while the cause is being investigated. The company says there has been no effect on the pressure inside the Containment Vessel, the amount of hydrogen gas inside the CV, or the amount of gas flowing through the Gas Management System.TEPCO's handout for the press (6/19/2012):

(TEPCO)’s final report on the Fukushima nuclear disaster has triggered a major backlash from prefectural residents and authorities who call it weak and even laced with falsehoods, it has been learned.
[...]
Yoshihiro Koyama, head of Fukushima Prefecture’s nuclear safety measures division [said] “We still don’t know what happened in the cores of the No. 1, 2 and 3 reactors, among other unclear information.
[...]
Meanwhile, Mayor Tamotsu Baba of the village of Namie points out a significant fabrication of data in TEPCO’s report. While the document states that “TEPCO employees visited the village of Namie from March 13, 2011″ to inform city authorities of details regarding the crisis, Baba says that they heard from TEPCO officials for the first time only in late March.
“This report is not just sloppy in content — it includes falsified information,” said Baba, who is expected to seek charges against the former TEPCO president and other officials for violating a liaison pact by not reporting to the Namie Municipal Government immediately after the outbreak of the disaster.
A 71-year-old resident who evacuated from Tomioka — inside the evacuation zone around the plant — and now lives at a temporary housing complex in the prefectural city of Koriyama, also criticized the report, saying that it is likely TEPCO may still be hiding information from residents.

Fuel rods in cooling pool have fanned safety worries
Workers at the crippled Fukushima nuclear plant will begin removing fuel rods from a damaged reactors a year ahead of schedule, a government minister said Thursday, a move to address concerns about the risk of a new quake that could cause a further accident and scatter more radioactive debris.
“We would like to start taking out undamaged fuel this year. Preparation is now under way,” Japan’s nuclear crisis minister, Goshi Hosono, told Reuters in an interview.
[...]
Tokyo Electric Power Co (Tepco) [...] had said in April it aimed to begin removing the fuel rods from the No. 4 reactor at the end of next year.
[...]
Tepco says its analysis shows the No.4 reactor building would hold up in a strong earthquake. But Japanese safety regulators ordered Tepco to recheck its findings last month after measurements showed one of the walls of the reactor building was buckling out by about 3 centimetres (1.2 inches).

The Real Risks At Oi

The SimplyInfo.org research team has been busy looking into the newly claimed safety efforts at the Oi nuclear plant in Japan. The Prime Minister and Fukui governor have given their approval to restart units 3 & 4 at Oi, ending Japan’s days of being nuclear free. Though Japan has been largely nuclear free for months as most reactors have been offline for an extended period of time. The reactors at Oi have been offline between 6 months to 1 year. KEPCO is now trying to rush the restart of unit 3 to a short few weeks. The longer a reactor is offline the more work is involved in restarting it.
Oi has a number of known issues and past safety problems that have not been resolved. The plant’s siting and design create a number of inherent risks. The safety upgrades are all illusion intended to give the public a false sense of safety while the powers that be in Japan go right back to business as usual gambling with the lives and livelihoods of everyone.
