The accident occurred on Wednesday morning.
The two subcontracting workers were suddenly splashed with water leaking from a container whose valve was not shut. The container was part of the contaminated water processing system.
TEPCO says one of the 2 workers was found to be exposed to 0.16 millisievelts of radiation, which is higher than the safety limit, and was decontaminated
The other, who was wearing a raincoat, was exposed to 0.14 millisievelts of radiation, a slightly smaller dose than the other man.
The utility says that the 2 workers did not complain of symptoms such as burns and they had no internal radiation exposure.
TEPCO is investigating how the accident occurred.
Last Sunday, 3 workers at the plant were exposed to radiation by mistake while they were replacing parts of the contaminated water processing system, which is key to bringing the crippled reactors under control.
