(Subscription Only) Title: Fukushima reactors briefly did not get enough coolant water: TEPCO
Date: 21:23 30 August
The operator of the Fukushima Daiichi nuclear power plant said Thursday that the amount of water injected into the crippled Nos. 1 to 3 reactors temporarily dropped below the level regarded as necessary to keep the fuel inside cool.
Although the sharp drop in the water volume did not last long enough to push up the temperature of the reactor pressure vessels, Tokyo Electric Power Co. said it will investigate the cause of the incident because water injection is the “most important” system to ensure the stable condition of the reactors.
The utility known as TEPCO noticed that the three reactors were not getting enough water injection at 3 p.m. Thursday. Workers operated valves to increase the water volume and they confirmed at about 4:30 p.m. that it recovered to the necessary level.
The original report had a different 2nd paragraph:

Tokyo Electric Power Co. said the drop in the volume of the water did not affect the temperature of the reactor pressure vessels, while adding that the company is investigating the cause of the incident.
