Toshiba system to cleanse water at Tepco plant

JIJI

Toshiba Corp. has unveiled the main part of a new system that can remove radioactive materials from water at the Fukushima No. 1 nuclear plant.

At present, the Sarry system, also developed mainly by Toshiba, is used to remove radioactive cesium from water at the plant.

The new system, called ALPS, can remove 62 types of radioactive substances — including strontium — which Sarry cannot, officials said Tuesday.

Toshiba hopes to begin tests in September so the new system can be put into service as soon as possible, the officials added.

The system is made up of pretreatment equipment that removes heavy metals and calcium, and 42 adsorption towers for radioactive decontamination.

The daily water treatment capacity is 500 tons. The amount of radioactive materials in the water will be lowered to levels below legal limits, the officials said.

Recovery teams

Tokyo Electric Power Co., facing a massive compensation bill for the Fukushima nuclear crisis, has set up two specialized bodies tasked with keeping its financial risks under control and promoting a comprehensive business reconstruction plan, sources said.

The beleaguered utility hopes to put its recovery on track by ensuring thorough risk management and implementation of the business program.

With a hike in electricity rates scaled back by the government and little chance of the restart of its massive Kashiwazaki-Kariwa nuclear complex in Niigata Prefecture, Tepco is facing snowballing red ink.

The utility established two cross-sectional teams in mid-July, each consisting of around 20 members. The teams include experts on corporate rehabilitation and senior officials from the Nuclear Damage Liability Facilitation Fund, which is helping the company pay compensation to victims of the nuclear disaster, according to the sources.

Of the two, the team in charge of risk management is to analyze cash flow and other funding issues over the next five years with the goal of averting a financial crisis.
