Clock Ticks On Fukushima Unit 5 Cooling Outage As Typhoon Hits Japan

TEPCO reported over the weekend that they found a leak in a valve that is part of the cooling system used for the spent fuel pool of unit 5. The system was stopped as they identified the leak. TEPCO noted they have about 9 days before the spent fuel pool would reach a heat level that they are required to report it to authorities (65 Celsius).
The “reactor auxiliary cooling system” was found to have the leak on the sea water side of the system past the heat exchangers. The way this system is designed they could pull water into the three heat exchangers but have no way to expel that sea water back out to sea as all three exchangers share one outlet pipe. Without a way to bypass the section with the broken valve the system is out of service.
TEPCO managed a very bizarre repair with patch, wood and …

“Strongest level” typhoon NEOGURI may hit Fukushima plant area on 711

↑ Satellite imagery at 17:30 UTC 7/7/2014

According to Japan Meteorological Agency, “very strong” typhoon NEOGURI may hit Fukushima plant area on 7/11/2014.

The central pressure is 930 hPa, maximum wind gust speed is 70 m/s (135 kt). Japan Meteorological Agency announces it is the strongest level of typhoon for July.

They published emergency weather warnings to Okinawa prefecture for once in a decade level of the high sea and storm and request to take an immediate action to shield.

It is expected to reach the main part of Japan on 7/10/2014.

They report NEOGURI would be weakened toward the main part of Japan, however they anticipate it to activate a seasonal rain front.

Eastern Japan therefore is required to be careful for heavy rain and storm before the typhoon reaches.

Tepco is planning to remove the cover of Reactor1 from early July.

You read this now because we’ve been surviving until today.
