Gas could indicate new Japan nuclear plant trouble
None
Officials detected a radioactive gas associated with nuclear fission at Japan's tsunami-damaged atomic power plant Wednesday, indicating there could be a new problem at one of its reactors. They injected a substance that neutralizes nuclear reactions as a precaution.
Gas from inside the reactor indicated the presence of radioactive xenon, which could be the byproduct of unexpected nuclear fission. Boric acid was being injected through a cooling pipe as a countermeasure because it can counteract nuclear reactions. (AP)
