Tepco Says No. 3 Reactor Temperature Falls to Below 100 Celsius
Baku, September 29 (AZERTAC). Tokyo Electric Power Co. said the temperature of the No. 3 reactor pressure vessel at its crippled Fukushima Dai-Ichi plant fell to below 100 degrees Celsius (212 Fahrenheit), one of the conditions for achieving cold shutdown.
The temperature on the outside of the base of the vessel was 98.4 degrees Celsius at 5:00 a.m. today from 102.7 degrees 24 hours earlier after the utility known as Tepco this month added a spraying system to cool the reactor, Junichi Matsumoto, a general manager, told reporters.
It doesn`t mean the reactor has reached cold shutdown status because the utility still needs to assess the amount of radioactive materials leaking from the reactor, he said. Temperatures remain higher than 100 degrees on other sections of the reactor, the utility said.
Temperatures on the No. 1 reactor remain below 100 degrees Celsius after reaching that level around Aug. 20, Matsumoto said. The temperature of the bottom of the No. 1 reactor vessel was 85.1 degrees today, according to a table provided by the company.
On the base of the No. 2 reactor the temperature was 112.6 degrees, according to Tepco.
Tepco has been pouring water into reactors after the March 11 earthquake and tsunami knocked out cooling system of the Fukushima Dai-Ichi plant, leading to three reactor meltdowns.
