TEPCO was running the test of the entire contaminated water treatment system since 12:20AM JST, June 16, but the test has been halted because of the leak found in one of the cesium absorption towers after 19 hours of running the test. The company was planning to run the test with the low contamination water for 30 to 40 hours before the full operation of the system with the high contamination water.
It looks to be part of the Kurion system which uses a series of towers filled with zeolite to absorb radioactive cesium.
Murphy's still alive and well at Fukushima.
From Asahi Shinbun (12:30AM JST 6/17/2011):
東京電力は１６日、福島第一原子力発電所にたまり続ける高濃度の放射能汚染水を浄化処理する施設の試運転中に、一部の装置から汚染水が漏れ出したこ とを明らかにした。装置は自動停止した。水が漏れた場所を見つけて修理するのに少なくとも半日はかかりそうだという。１７日に予定する浄化施設の本格稼働 が遅れる可能性が高まっている。
TEPCO disclosed on June 16 that there was a leak in one of the subsystems during the test run of the entire water treatment system that will treat high contamination water at Fukushima I Nuclear Power Plant. The system was shut down automatically. According to TEPCO, it may take at least half a day to identify the location of the leak and repair. It is increasingly likely that the full-scale operation of the water treatment system, which is scheduled to start on June 17, will be delayed.
水漏れがあったのは、施設のうち、放射性セシウムを吸着させる円筒形の装置。午後７時２０分に警報が鳴って装置が自動停止した。午後８時ごろ、作業員が 直径９０センチ、高さ２・３メートルほどの装置を入れた金属製の箱に３０センチほど水がたまっているのを確認したという。さらに箱の外にまで汚染水が漏れ だしていた。
The leak was found in one of the cylindrical equipment to absorb radioactive cesium. The alarm sounded off at 7:20PM JST [on June 16] and the system was shut down automatically. At 8:00PM, the workers went in and visually confirmed the leaked water 30 centimeter deep inside the metal box that houses the cylinder, 90 centimeter in diameter and 2.3 meter in height. The water had spilled outside the box, too.
TEPCO said the detailed investigation was needed to figure out what had caused the leak.
