Annual Radiological Environmental Operating Report
Reference:
Letter from Brian Wake (Constellation Energy Generation, LLC) to U. S. Nuclear Regulatory Commission, "Radioactive Effluent Release Report for 2022," dated April 28, 2023 Pursuant to Technical Specifications Section 5.6.2, enclosed is the 2022 Radiological Environmental Operating Report for Quad Cities Nuclear Power Station. This Report contains the results of the Radiological Environmental Monitoring Program (REMP). In addition, the 2022 Radiological Groundwater Protection Program (RGPP) Report is included as Appendix F of Enclosure 1. is a correction to the Radioactive Effluent Release Report for 2022 which was submitted by the referenced letter.

Regional Administrator - NRC Region Ill NRC Senior Resident Inspector - Quad Cities Nuclear Power Station Annual Radiological Environmental Operating Report Correction/Errata for the 2022 Annual Radioactive Effluent Release Report
Errata/Correction to the 2022 ARERR The following paragraph explains the errata data that has been identified for the 2022 ARERR:
A discussion on the inoperability of the Main Chimney High Range Noble Gas Monitor for greater than 7 days, was inadvertently omitted from the 2022 Quad Cities Annual Radiological Effluent Release Report. The following is a synopsis of the inoperability of the Main Chimney High Range Noble Gas Monitor:
On May 11, 2022, the Main Chimney High Range Noble Gas Monitor was declared inoperable. On May 31, 2022, the Main Chimney High Range Noble Gas Monitor was declared operable following repairs and successful calibration and functional tests The inoperability of the Main Chimney High Range Noble Gas Monitor required entry into ODCM Section 12.2.2, "Radioactive Gaseous Effluent Monitoring Instrumentation Report,"
Condition F, due to less than the minimum number of OPERABLE channels of the Main Chimney High Range Noble Gas Monitor. Action F.1 requires establishment of the preplanned alternate method of monitoring within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This action was completed on May 11, 2022, via the Main Chimney GE monitors. Action F.2 requires the instrument channel to be restored to OPERABLE status within 7 days. The 7-day time requirement was reached on May 18, 2022 without the monitor being restored to operable. The 30 day requirement to submit a special report to the NRC outlining the action(s) taken, the cause of the inoperability, and the plans and schedule for restoring the system to OPERABLE status was completed on June 10th, 2022. This special report is documented in ADAMS as ML22161A962.
Resolution of this issue within the 7-day requirement was not feasible due to multiple failures associated with the high range detector and electronics.
Additional errors were editorial and listed as follows:
- 1. The header for the entirety of the Joint Frequency Tables all read 2021 instead of 2022
- 2. The last page of the report was improperly number "79 of 79" instead of "78 of 78".
