Fukushima Status 3/19/11
The following is the latest status of each nuclear reactor at Tokyo Electric Power Co.’s crippled Fukushima Dai-Ichi power plant.
No. 1: Workers are ready to restore power to the No. 1 and No. 2 reactors, Deputy Chief Cabinet Secretary Tetsuro Fukuyama said on NHK Television today. The reactor was damaged on March 12 by a hydrogen explosion that destroyed the building walls. The reactor is rated level five in terms of threat on an international scale of 1-7.
No. 2: Engineers hope to use the power cable attached to the No. 2 reactor as a hub to restore electricity to the other five reactors, Tokyo Electric said. A March 15 explosion may have damaged the containment chamber. The reactor is rated a level five threat.
No. 3: Firefighters sprayed to control the reactor between 2 p.m. yesterday and 3:40 a.m. today, NHK reported. Similar actions March 18 managed to replenish water in the spent-fuel pool. Japan’s Nuclear and Industrial Safety Agency said the radiation level has dropped near the reactor. The reading fell to 2,906 microsieverts per hour at 9 p.m. yesterday, down from 3,443 microsieverts per hour seven hours earlier, NHK said. A March 14 explosion damaged the unit’s fuel cover. The reactor is rated a level five threat.
No. 4: This reactor was undergoing maintenance when the March 11 quake struck. A fire broke out in the pond containing spent-fuel rods. The nuclear agency said March 17 there may be no water in the cooling pool. Japanese Self-Defense Forces sprayed water on the reactor this morning. Another dousing is expected in the afternoon, NHK said. Rated four in terms of threat.
No. 5: The temperature in the spent fuel pool fell to 37.1 degrees Celsius, as of 7 a.m., Kyodo News said. The temperature was 67.6 degrees 9 a.m. yesterday, Kyodo said. Temperatures should be kept below 25 degrees Celsius, according to IAEA guidelines. The unit was idle for maintenance before the earthquake.
No. 6: The temperature in the spent fuel pool fell to 41 degrees Celsius, as of 7 a.m., Kyodo News. A backup generator was fixed yesterday, according to a company press release. There’s no concern over water levels at the reactor and the company believes there hasn’t been any leakage of coolant in the unit’s containment vessel. The unit was idle for maintenance before the earthquake.
