1.0 INTRODUCTION
Duke Energy Progress, LLC (previously known as Duke Energy Progress, Inc., Progress Energy Carolinas, Inc., and Carolina Power & Light Company) received a low-power Facility Operating License (No. NPF-53) and full-power Facility Operating License (No.
NPF-63) for the Shearon Harris Nuclear Power Plant, Unit 1 (HNP), from the U.S.
Nuclear Regulatory Commission (NRC) on October 24, 1986, and January 12, 1987, respectively. The NRC issued a Renewed Facility Operating License (No. NPF-63) on December 17, 2008, extending operations until October 24, 2046. Appendix B (the Environmental Protection Plan (EPP) [nonradiological]) of the renewed operating license requires submittal of an Annual Environmental (Nonradiological) Operating Report to the NRC describing the implementation of the plan during the previous year. The purpose of this document is to fulfill the requirement for the period of January 1 through December 31, 2023.
On September 18, 2015, the North Carolina Department of Environment and Natural Resources (NCDENR) officially became the North Carolina Department of Environmental Quality (NCDEQ) when Governor McCrory signed the 2015-2016 state budget into law. NCDEQ will be used in this report.
2.0 PLANT CONSISTENCY REQUIREMENTS
[EPP Section 3.0]
2.1 Plant Design and Operation There were no changes in plant design or operation and there were no tests or experiments performed which involved a potentially significant unreviewed environmental question during the reporting period.
2.2 Reporting Related to the NPDES Permit As required by National Pollutant Discharge Elimination System (NPDES) permit NC0039586, monitoring data was submitted to the North Carolina Department of Environmental Quality (NCDEQ) via monthly discharge monitoring reports and separate correspondence as warranted.
The current NPDES permit NC0039586 became effective on September 30, 2021, by NCDEQ. This permit will expire on August 31, 2026.
2.3 Reporting Related to the NPDES Industrial Stormwater Permit NPDES Industrial Stormwater Permit NCS000606 was initially issued on September 27, 2023, with an effective date of November 1, 2023. This permit will expire on October 31, 2028.
With the issuance of this permit, the stormwater requirements of NPDES permit NC0039586 were transferred to the NPDES Industrial Stormwater Permit NCS000606.
Modification to specific pages of the NPDES Industrial Stormwater Permit NCS000606 were issued by the NCDEQ as a Minor Permit Modification on November 8, 2023, without permit revision. Sampling and observation requirements were scheduled to start on January 1, 2024.
2 3.0 UNUSUAL OR IMPORTANT ENVIRONMENTAL EVENTS
[EPP Section 4.1]
No occurrence of an unusual environmental event that would indicate or could result in a significant environmental impact causally related to plant operations occurred during the reporting period. No releases or exceedances of permit conditions caused any significant environmental impact. The existence of biofouling organisms (Asiatic clams, Corbicula fluminea) and the presence of troublesome aquatic vegetation (hydrilla, Hydrilla verticillata) in the Harris Reservoir are considered important topics worthy of inclusion in this report. No zebra mussels were detected at any location in the Harris Lake or the auxiliary reservoir during 2023.
3.1 Aquatic Biological Monitoring A. Inspections for Asiatic clams (Corbicula fluminea) in the Harris Nuclear Plant Emergency Service Water System (e.g., intake structures)
The Emergency Service Water (ESW) intake structure is inspected on a frequency of no greater than four and a half years in accordance EPT-168 (Engineering Performance Test) and Periodic Maintenance Identification Numbers (PMIDs) 23528 and 23529 as part of HNPs Generic Letter 89-13 Testing and Inspection Program. No bays were inspected in 2023.
No Asiatic clams were observed during downstream heat exchanger inspections. No clogging events of HNP cooling water systems were observed during 2023 because of Asiatic clam infestation.
B. Monitoring aquatic vegetation Main Reservoir The North Carolina Division of Water Resources Aquatic Weed Program (NCAWP) conducted an aquatic vegetation survey in the main reservoir in the fall of 2023. The NCWAP did not detect any submerged vegetation (Hydrilla and Black Mat Algae, Lyngbya sp.), in the reservoir. Duke Energy Progress, LLC, personnel also conducted qualitative aquatic vegetation surveys during routine environmental monitoring surveys and did not detect Hydrilla or Lyngbya in the reservoir. Submerged vegetation was not observed in the intake embayment or canal. Grass carp were not stocked in the main reservoir in 2023. No new species of aquatic plants were observed in the main reservoir.
No impacts to HNP operations from aquatic vegetation occurred in 2023.
Auxiliary Reservoir Hydrilla was not observed in the auxiliary reservoir, intake canal, or the shoreline adjacent to the auxiliary intake canal. There were a few scattered areas of Alligator Weed (Alternanthera philoxeroides) but only in very small amounts. No submerged aquatic vegetation was observed in the intake canal and embayment. Grass carp were not stocked in the auxiliary reservoir in 2023.
No impacts to HNP operations from aquatic vegetation occurred in 2023.
3 3.2 Combined Construction and Operating License Application Evaluations In a letter dated February 18, 2008, Carolina Power & Light Company applied for a combined construction permit and operating license (COL) for two AP1000 advanced pressurized water reactor units to be located at the HNP site. In the initial application, Carolina Power & Light Company relied on Integrated Resource Plans (IRPs) prepared for the North Carolina Utilities Commission and the Public Service Commission of South Carolina to demonstrate the need for the two units.
The IRPs used a 15-year period for forecasting native load requirements, supply-side and demand side resources, and options considered for satisfaction of the load requirements and other system obligation. Duke Energy Progress (DEP) continued to evaluate the need for power, however the commercial operation dates for the two units no longer fell within the 15-year planning window of the IRP. In a letter dated May 2, 2013 (Agencywide Documents Access and Management Systems (ADAMS) Accession No. ML13123A344), DEP requested that the NRC suspend review of the COL application for the two units at the HNP site.
Additionally, requests for exemption from the 10 CFR 50.71(e)(3)(iii) Final Safety Analysis Report updates were submitted by DEP per letters dated August 12, 2015 (ADAMS Accession No. ML15226A353), October 13, 2016 (ADAMS Accession No. ML16288A815), and December 2, 2019 (ADAMS Accession No. ML19337A620),
with the most recent receiving approval from the NRC on April 6, 2020 (ADAMS Accession No. ML20029E967), extending the exemption date to December 31, 2024.
No work was performed in 2023 in support of the COL for the two units at the HNP site.
3.3 Harris Land Sales Five sales of property outside of the Owner Controlled Area occurred in 2023.
A. Town of Holly Springs On January 17, 2023, a deed was recorded with the Wake County Register of Deeds for 4.11 acres sold to the Town of Holly Springs, for a new Fire Station in the Holly Springs, North Carolina (NC), area.
