Plant-related Parameters

Plant-related data is made available.

Real-time Data

Temperature of reactor pressure vessel	Unit 1	Unit 2	Unit 3
Temperature in reactor containment vessel	Unit 1	Unit 2	Unit 3
Radiation levels in reactor containment vessel	Unit 1	Unit 2	Unit 3
Hydrogen concentration in reactor containment vessel	Unit 1	Unit 2	Unit 3

Main monitoring parameters can be confirmed as water injection flow rate to the reactors is reduced.

Notice

October 19, 2020 ・Date of releasing one-hourly and six-hourly data (CSV) was changed to the latest measurement day due to a revision of operational procedure.
October 2, 2020 ・Date of releasing one-hourly and six-hourly data (CSV) was changed from the latest measurement day to the next day due to a revision of data disclosure procedure.
October 2, 2020 ・An error contained in Unit 1 six-hourly data (CSV) in the column of "airborne radioactive concentrations (long half-life noble gas) at the nitrogen gas injection system to PCV" at 11:00 on September 30, 2020 was corrected on October 1, 2020 (original: 8.66E-02 → corrected: 9.06E-02).
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.
