Fukushima water decontamination system breaks down

Read this Jan. 9 story from RT.com, reporting on the failure of the water decontamination system at Japan’s badly-damaged Fukushima Daiichi nuclear power plant.

The operator of the crippled Fukushima nuclear plant, TEPCO (Tokyo Electric Power Company) has stopped using its systems to decontaminate radioactive water at the facility, Japanese broadcaster NHK reported.

The Advanced Liquid Processing System, or ALPS, has been utilized to liquidate radioactive substances from contaminated water stored at the plant.

The crane to get rid of the container from the ALPS ceased working on Tuesday.

On Wednesday, TEPCO stopped operating all 3 ALPS systems at the facility. The company officials say the system may take a long time to restart.

The container where the radioactive substances are stored has to be replaced when it fills up.

TEPCO, the operator of the Fukushima Daiichi plant, crippled in the 2011 earthquake and tsunami, said that the company plans to decontaminate all radioactive water stored in the tanks by March 2015, NHK reported.

That’s despite the company officials telling The Japan Times a month ago that the radioactive water will be decontaminated by the end of fiscal 2014.

It’s not the first time that the ALPS system has experienced trouble: at the beginning of December, the system was reported to have broken down during trial operations.

The Advanced Liquid Processing System (ALPS) consists of 14 steel cylinders, through which the contaminated water is filtered. After the filtering, waste materials like the absorbent and remaining sludge are transferred to high-integrity containers (HICs) that are transported to a temporary storage facility.

The ALPS can remove 62 different types of radionuclides, including strontium and cobalt from contaminated water.

The year has started off badly for the Fukushima Daiichi plant: a few days ago, a Japanese worker, who participated in the mending of the plant to avoid further radiation leaks, has revealed that adhesive tape had been used to deal with the issue of sealing in radioactive water.

The 48 year-old, Yoshitatsu Uechi, an auto mechanic and tour-bus driver, was one of the 17 workers to be sent to the crippled facility to make more containers to store the contaminated water.

    General Electric designed and installed this facility, yet they escape all mention and responsibility.
    Meanwhile they pay no tax and are a major player in privatizing our BC Hydro through independent power production.
