Main monitoring parameters can be confirmed as water injection flow rate to the reactors is reduced.
- Water injection flow rate to reactor, containment vessel gas control system dust monitor Hourly data (CSV), Six-hourly data (CSV)
- Temperature in containment vessel, water injection flow rate to reactor Temperature in primary containment vessel

Main monitoring parameters can be confirmed as water injection flow rate to the reactors is reduced.
- Water injection flow rate to reactor, containment vessel gas control system dust monitor Hourly data (CSV), Six-hourly data (CSV)
- Other monitoring parameters (temperature at upper part of reactor pressure vessel, containment vessel pressure, containment vessel water level) Six-hourly data (CSV)
Notice
- As the water level gauge in the Unit 6 reactor was updated, the water level has been recorded by a digital gauge instead of an analog gauge since July 8, 2025.
- Following change was made to "Unit 2 six-hourly data (CSV)" on November 11, 2024 due to installation of the Unit 2 fuel removal work platform:
Name of “Dust concentrations in the exhaust gas from the reactor building” was changed to “Dust concentrations in the exhaust gas from the reactor building and the fuel removal work platform.” - ""Due to modification of Centralization Remote Monitoring System at the Unit 1-4, following changes have been made in Unit 1-4 "six-hourly data (CSV)":
The name of the plant data "Airborne radioactive concentration (dust) at the nitrogen gas injection system to PCV" has been changed to "Airborne radioactive concentration (dust) (A) at the nitrogen gas injection system to PCV".
The name of the plant data "Airborne radioactive concentration (long half-life noble gas) at the nitrogen gas injection system to PCV" has been changed to "Airborne radioactive concentration (long half-life noble gas) (A) at the nitrogen gas injection system to PCV".
Plant data "Airborne radioactive concentration (dust) (B) at the nitrogen gas injection system to PCV" and "Airborne radioactive concentration (long half-life noble gas) (B) at the nitrogen gas injection system to PCV" have been added. - Gaps in data may occur due to equipment maintenance inspections, etc.
- Steam (mist) may occur at the upper part of the reactor building due to outside temperature and humidity conditions.
