Here are the measurement results of temperatures inside the Unit 1 Primary Containment Vessel at
Fukushima Daiichi Nuclear Power Station.
- ※Here are the measurement points for each temperature.
- ※FoFor reference: The following is the “Limiting Conditions of Operations” designated in the implementation plan for temperatures
inside the Primary Containment Vessel:
・Temperature inside the Primary Containment Vessel: Overall, no tendency for significant rise in temperature
Announcement
- ○Pressure inside Unit 1 PCV has been lowered to be safe by increasing exhaust gas flow rate of gas control facility since April 4 in order to minimize risks of emitting dust during the operation of forming an access route for the PCV internal investigation at the Unit. We regard fluctuations for a part of temperature readings inside the PCV occurring in conjunction with the above as being within the range of past performance at this moment.
- ○Data may change or be missing due to equipment failure or regular inspections.
