Tokyo (CNN) -- Workers placed an endoscope into a nuclear reactor at Japan's damaged Fukushima Daiichi nuclear plant Thursday, marking the first glimpse inside one of the crippled reactors.
Tokyo Electric Power Co. said the endoscope equipped with a camera took pictures when it was inserted into reactor No. 2.
Massive steam and water drops made it difficult to get a clear vision, said Aya Ohmura, who works for the power company.
Ohmura said the company will provide more details on the findings.
The company has been trying to fix damage to the nuclear plant caused by the massive earthquake and tsunami that hit Japan on March 11, 2011.
The disaster killed more than 15,000 people in northeastern Japan and triggered plumes of radioactive particles from the damaged nuclear power plant.
Three reactors at Fukushima suffered meltdowns, the company has said.
