Japan pumps water into reactor to contain radioactivity, Deutsche Presse-Agentur, June 20, 2011:
Tokyo Electric Power Co (TEPCO), which runs the Fukushima Daiichi Nuclear Power Station, started Sunday to pour water into a pool on the top floor of reactor 4 of the six-reactor plant after it discovered the water level had dropped to about one-third of its capacity, public broadcaster NHK reported.
The drop caused equipment in the pool to be exposed, releasing high levels of radiation, officials said. [...]
The radiation levels at reactor 4 have been preventing workers from entering the structure to conduct repairs.
