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 primary containment vessel	Unit 1	Unit 2	Unit 3
Radiation levels in primary containment vessel	Unit 1	Unit 2	Unit 3
Hydrogen concentration in primary 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

Due to the review of the records of the operation diary of Units 1 to 4, "Data for every 1 hour / 6 hours (CSV)" (excluding Units 5 to 6) has been updated. (Change List (62.2KB) )
Maximum and minimum values of “Dust radiation monitor Channel A at the exhaust system for Unit 4 fuel removal cover” from June 1 to June 15 are as follows:Maximum value: 2.88E-07 (Bq/cm3) Minimum value: 5.80E-08 (Bq/cm3)
Although there are slight fluctuation in the indicated values, we have confirmed that there is no abnormal increase in the indicated values compared to before and after said term and that there are no alarm for high radiation in concerned area.
*Reference: Data from January 1, 2022 to May 31, 2022
Maximum value: 5.11E-05 (Bq/cm3) Minimum value: 6.36E-08 (Bq/cm3)
Due to changes in the implementation plan due to the completion of fuel removal from the Unit 3 spent fuel pool, the spent fuel pool water temperature column in the summary table and the Unit 3 6-hourly data (CSV) will be displayed as "-" from November 26.
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.
