Contaminated Water Treatment System Stops for the Nth Time at Fukushima I Nuke Plant

Yomiuri Shinbun (3:59PM JST 8/26/2011):

東京電力は26日、福島第一原子力発電所の汚染水処理装置が一時的に停止したと発表した。

TEPCO announced on August 26 that the contaminated water treatment system at Fukushima I Nuclear Power Plant stopped temporarily.

 放射性セシウムを吸着させる米キュリオン社製の装置から、仏アレバ社製の浄化装置へ送水するポンプが午後2時21分に自動停止した。

The pump that transfer the treated water from Kurion's cesium absorption system to AREVA's co-precipitation system stopped automatically at 2:21PM.

 処理装置が停止したのは、8月12日に制御システムの信号異常に伴うトラブル以来。東電は何らかの原因でポンプに負荷がかかり過ぎたためと見て、詳しい原因を調べている。

The treatment system last stopped on August 12 due to the abnormal signal from the control system. TEPCO thinks the stoppage this time is due to too much load on the pump, and is currently looking into the cause.

Virginia Power Plant Initiating Cold Shutdown for Inspections:

"Among other concerns related to seismic risk, inspectors found other small vulnerabilities at the plant, such as seismic floodwalls being located in a non-seismic building and certain safety equipment that was not designed to withstand an earthquake."

Another thing I've found is North Anna NPP is designed for a 5.9 on the stone portions of the facility and a 6.1 on the soil portion. It is interesting that the USGS at one point rated the quake at 5.9 only to downgrade it a few hours later. I'm sure intensity revisions happen all the time but it still makes me wonder if the revision was ordered to quell the critics.
