Workers Re-enter Japanese Reactor Building for First Time VOA News May 05, 2011 Japanese officials say workers Thursday entered the number one reactor building at the crippled Fukushima nuclear plant for the first time since an explosion tore the roof off the building almost two months ago. Officials with the Tokyo Electric Power Company said a total of 12 workers were tasked with setting up a ventilating system to reduce radiation levels in the air inside the building. That will enable workers to go back later this month to work on repairing the reactor's crucial cooling systems that were damaged by the March 11 earthquake and tsunami. TEPCO said the workers are equipped with protective suits, masks and air tanks, and are working in groups of four. No individual was to spend more than 10 minutes inside the building. The company said the workers were seeking to connect eight pipes that will carry air from inside the building to a ventilator that has already been installed in an adjacent turbine building. If the operation is successful, TEPCO hopes to begin work on May 16 to rebuild the water circulation system that keeps the reactor's fuel rods from overheating. For weeks, temporary systems including fire hoses have been used to keep the rods cool. Radiation has been leaking from the plant since the March 11 earthquake and tsunami damaged cooling systems at all six of the plant's reactors. Elevated radiation levels have been detected in the soil, sea water, fish and agricultural products for kilometers around the plant. Tens of thousands of people have been evacuated.
