  • Here are the measurement points for each temperature.

  • For 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

  • From November 2020 to 2022 (scheduled), measuring instruments for Temp (8) (TE-16-007) and Temp (9) (TE-16-008) are removed due to internal investigation and experimental retrieval.
    Since the data of Temp (8) and Temp (9) are missing during this period, the measurement values are displayed as "-" and the measurement graphs are not displayed.
  • Data may change or be missing due to equipment failure or regular inspections.
