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
- Water level inside PCV (bubbler water level) in Unit ３,４ six-hourly data (CSV) was excluded from planned data monitoring on May 1, 2026. Accordingly, appropriate item is displayed as blank.
- Since data collection of instruments confirmed to be unnecessary for monitoring have been completed on May 1, 2026. Accordingly, following items are displayed as blank:
< Unit 1 six-hourly data (CSV)>
Pressure of nitrogen gas injection to PCV, Primary Pressure of nitrogen gas injection to RPV(A), Secondary Pressure of nitrogen gas injection to RPV(A), Primary Pressure of nitrogen gas injection to RPV(B), Secondary Pressure of nitrogen gas injection to RPV(B), JP side (A) N2 pressure and JP side (B) N2 pressure
< Unit 2 six-hourly data (CSV)>
Pressure of nitrogen gas injection to PCV, Primary Pressure of nitrogen gas injection to RPV(A), Secondary Pressure of nitrogen gas injection to RPV(A), Primary Pressure of nitrogen gas injection to RPV(B) and Secondary Pressure of nitrogen gas injection to RPV(B)
< Unit ３,４ six-hourly data (CSV)>
Pressure of nitrogen gas injection to PCV, Primary Pressure of nitrogen gas injection to RPV(A), Secondary Pressure of nitrogen gas injection to RPV(A), Primary Pressure of nitrogen gas injection to RPV(B) and Secondary Pressure of nitrogen gas injection to RPV(B) - Since data collection of instruments (Volume of water injection to RPV(FDW+CS), Area monitor of the central control room, No.31 area monitor of the central control room, and Dust radiation monitor Channel A at the exhaust system for Unit 4 fuel removal cover) confirmed to be unnecessary for monitoring have been completed on December 8, 2025. Accordingly, appropriate items are displayed as blank.
- Data for "PCV temperature (TE-16-002)" in the Summary table and data for "PCV temperature (TE-16-002)" and "PCV temperature (TE-16-004)" of the Unit 3,4 six-hourly data (CSV) will be missing and displayed as "-" due to Unit 3 PCV internal investigation from October 24, 2025.
- 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.
