Reference:

Letter from Brian Wake (Constellation Energy Generation, LLC) to the U.S.

NRC (Regional Administrator, Region Ill), "Radioactive Effluent Release Report for 2022," dated April 28, 2023.

Pursuant to Technical Specifications Section 5.6.3 and 10 CFR 50.36a, enclosed is the Quad Cities Nuclear Power Station Radioactive Effluent Release Report for January through December 2022. This follow-up information is the second submittal of errata for the 2022 Annual Radioactive Effluent Release Report. Data will replace the Radioactive Effluent Release Report submitted under the April 28, 2023 letter.

Should you have any questions concerning this letter, please contact Blake Young at (309) 227-3200.

Errata/Correction to 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:

Multiple data errors were identified in the 2022 Annual Radiological Effluent Release Report for the summation of all gaseous releases, as well as batch liquid releases. The data errors were observed in the following sections of the report:

All four quarters of fission and activation gases and the associated annual total, ist Quarter gaseous particulates and associated annual totals, 4th Quarter Tritium and Carbon-14 results and associated annual totals, and 3rd and 4th Quarters percent of organ dose limit.

The 2nd Quarter batch liquid release was updated to include Fe-55 results and the updated annual totals.

Information for the total liquid batch releases were updated including, total time, maximum time, average time, and minimum time.

To reflect the updates for the continuous gaseous releases, Total Body dose, Organ dose, and Carbon-14 dose to total body and organ and percentages were all updated for Gaseous Dose to a Member of the Public.

The updates to both the gaseous and liquid data also updated the 40 CFR 190 Direct Radiation Dose to a Member of the Public for Total Body, Organ, and Thyroid dose and the associated 40CFR190 percent of limits.

All updates listed above reflect the changes in the 10CFR20.1301(a)(l) Compliance Assessment. Unit 1, Quarter 3 and associated Percent of Limit and Unit 2, Quarter 4, Year Total, and associated Percent of Limit were updated.

Quad Cities Nuclear Power Station 2022 Annual Radioactive Effluent Release Report During the period that the wells were routed to the discharge bay, only tritium was detected in the well discharge at levels above the required limit of detection. A total of 3.62E+O0 Ci of tritium was released to the Mississippi River via this abnormal release. The associated dose impact to members of the public from this abnormal release was calculated to be 2.GSE-07 mRem to the Child/Liver dose pathway. The total body dose associated with this abnormal release was calculated to be 2.65E-07 mRem to the Child Total Body. The associated curies and doses due to this release were included in the 2021 Annual Radiological Effluent Release Report Summation of All Releases Table (page 6 of the 2021 ARE RR), Mississippi River Continuous Mode (page 7 of the 2021 ARE RR) and Radiological Impact on Man (page 18 of the 2021 AR ERR).

Remediation of MW-R-2D2 continued th rough the 2022 calendar year, from January 1 st through December 31st, 2022. A total of 1.65E+07 gallons were released to the Discharge Bay Outfall. Starting January 3rd, 2022, sampling frequency was reduced to once every two weeks. Samples have been consistently less than detectible values for Tritium (H-3) and all other analytes. Monthly composite samples continue to be analyzed for gross alpha, Fe-55, Ni-63, Sr-89, and Sr-90. LLDs and sampling requirements for this monitored abnormal release are identical to the requirements listed in the ODCM for routine liquid effluent analysis.

The Quad Cities calculated annual doses from Carbon-14 releases have been calculated using the methodologies outlines in the ODCM. The resultant estimated releases of Carbon-14 resulted in a dose contribution of 1.84E-0lmRem to organ dose {98.7%) and 3.67E-02 mrem to total body dose (90.7%).

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. Resolution of this issue within the 7-day requirement was not feasible due to multiple failures associated with the high range detector and electronics.
