A new fire was found at the Fukushima Daiichi Reactor 4 on Wednesday morning in Japan (Tuesday night in New York time), reported CNN.

The fire, the second in two days, occurred at the northeastern corner of the Reactor 4 building.

Information on the effect of it on radiation levels is not yet available. The first fire did not elevate radiation levels for a sustained period of time.

The first explosion at Reactor 4 created two big holes in the container that holds the nuclear fuel rods. The fuel storage area then ignited into flames, resulting the direct release of radioactive materials into the atmosphere.

Reportedly, much of the leaked radiation came in the form of steam from boiling water, which is not as dangerous as if it were emitted by the fuel rods directly.
