Japan nuclear operator:more water needed for units 1,2, and 3

TOKYO, March 22 (Reuters) - The operator of Japan's stricken nuclear power plant said on Tuesday more water injections were needed to cool down units 1, 2 and 3.

Tokyo Electric Power also said data showing a rise in temperatures around the reactor core of the No. 1 unit is a concern and it was considering a way to further cool it down. (Reporting by Risa Maeda; Editing by Chris Gallagher)
