The operator of the Fukushima Daiichi nuclear power plant says it will extract air from troubled reactors at the plant to measure the amount of radioactive substances. […]
The operation is intended to obtain accurate data on what kind of radioactive substances are being released and in what quantity.
The air extraction is expected to begin later on Friday for the No.1 reactor and in early August for the No.2 unit. No plans have been decided for the No.3 reactor due to high radiation levels in part of its building.
NHK mentions that TEPCO doesn’t know where the melted fuel is inside the reactors or the actual level of radioactive particles still being released:
- TEPCO hopes the findings may also help the company grasp the extent of leakage of nuclear fuels into the containment vessels.
- Up to around one billion becquerels of radioactive substances are believed to be released every hour from reactors No.1, 2 and 3. It is not known how accurate this figure is because it was worked out by taking readings of the air on the plant’s premises.
