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
- From March 18 to 22, 2021 (scheduled), "Temperature in SFP" in Unit 5 hourly data will be displayed as "-" due to equipment inspection.
- February 1,2021・Since data collection of equipment (monitors for reactor water level, pressure at reactor pressure vessel and PCV atmospheric radiation) confirmed to be unnecessary for monitoring based on the technical evaluation has been completed in line with the update work of the digital recorder of each unit, data display was changed to blank.
- December 31, 2020 ･An error contained in Unit 3,4 six-hourly data (CSV) in the column of Unit 3"airborne radioactive concentrations (dust) at the nitrogen gas injection system to PCV" at 11:00 on December 30, 2020 was corrected on December 30, 2020 (original: 1.55E-06 → corrected: 1.55E-05).
- December 7, 2020 Of the "Hourly/Six-hourly data (CSV)", value of "Primary Pressure of nitrogen gas injection to PCV" and the name of "Secondary Pressure of nitrogen gas injection to PCV" of the Unit 2 six-hourly data (CSV), were changed due to replacing of monitoring equipment.
・Value of "Primary Pressure of nitrogen gas injection to PCV" was changed from "-" to blank.
・Name of "Secondary Pressure of nitrogen gas injection to PCV" was changed to "Pressure of nitrogen gas injection to PCV". - November 10, 2020・Data for "PCV temperature (TE-16-007)", "PCV temperature (TE-16-008)" and "Water level inside PCV" of the Unit 2 six-hourly data (CSV), which is one of the "Hourly/Six-hourly data (CSV)", will be missing from November 10, 2020 in conjunction with PCV internal investigation and trial removal work.
- 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.
