NRC Request for Additional Information - Oconee LAR 2018-01 (EPID L-2018-LLA-0042)
- Chris, By letter ONS-2018-014 dated February 12, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18046A080), Duke Energy Carolinas, LLC (the licensee) submitted License Amendment Request (LAR) No. 2018-01 for the Oconee Nuclear Station (Oconee). The licensee applied for changes to the Duke Energy Physical Security Plan (PSP) under the provisions of Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Domestic Licensing of Production and Utilization Facilities, Section 50.90, Application for amendment of license, construction permit, or early site permit. In its application, the licensee stated that it is voluntarily proposing these changes to further increase the margin of protection for certain associated components and equipment whenever the Standby Shutdown Facility (SSF) is declared inoperable.
The U.S. Nuclear Regulatory Commission (NRC) staff determined that the following requests for additional information (RAIs) are necessary to complete processing of LAR No. 2018-01. The NRC staff emailed a draft of the RAIs to the licensee on May 23, 2018, and had a clarification call with the licensee on June 13, 2018.
Based on that call, the NRC clarified draft RAI-14 to explain what it meant by a noise-sensitive receptor. As discussed with you on July 5, 2018, the NRC staff has also since determined that it would send draft RAIs 1 through 9 in a final version (and renumbered) at a later date because the staff identified another potentially related draft RAI for that set. Therefore, draft RAIs 10-26 are renumbered and reordered below. Their content has not changed other than the clarification noted above in RAI-6. As previously discussed with you on July 5, 2018, the NRC staff requests the licensee to respond to the RAIs in this email within 30 days of this email.
RAI-1
The NRC staff requests the licensee to provide an unredacted revision of its no significance hazards consideration and environmental analysis that were provided in the application that can be made publicly available.
RAIs 2 through 17 In its application, the licensee proposed changes to its PSP, including modifications to physical security structures that may affect the human and natural environment. In accordance with the National Environmental Policy Act of 1969, as amended (NEPA) and NRCs regulations implementing NEPA (i.e., 10 CFR 51), the NRC staff is required to prepare an Environmental Assessment to evaluate the impacts to the human and natural environment from the proposed action. Section 51.41 of 10 CFR states that the NRC staff may require environmental information from an applicant for an amendment to an operating license to aid the NRC staff in complying with NEPA. Sections 5 and 6 of the licensees application includes an environmental considerations analysis. However, the analysis did not describe details regarding construction activities, the affected environment where construction would occur, and additional information to evaluate the extent and intensity of the impacts from the proposed modifications. In order to comply with NEPA and 10 CFR 51 and to prepare an environmental assessment, the NRC staff requests the following additional information. The NRC staff requests that the licensee provide a publicly available version of the responses.
The following RAIs (2-7) pertain to the type and extent of proposed construction activities.
2
RAI-2
The NRC staff requests the licensee to provide an overview of the proposed construction activities, including any ground disturbing activities, such as excavation, clearing, and grading, and to describe both the spatial and temporal extent of any ground disturbing activities.
RAI-3
The NRC staff requests the licensee to describe the construction laydown areas, construction equipment (including the maximum height of equipment), and the duration of construction activities.
RAI-4
The NRC staff requests the licensee to discuss whether any chemicals or other contaminants may be used during construction activities.
RAI-5
The NRC staff requests the licensee to describe whether any tree cutting would occur.
RAI-6
The NRC staff requests the licensee to provide an estimation of air emissions and noise levels from construction equipment, identify the distance from the construction site to the nearest noise-sensitive receptors (e.g., nearby sensitive receptors such as residences, schools, or nursing homes), and include estimated noise levels at the nearest noise-sensitive receptor.
RAI-7
The NRC staff requests the licensee to describe the extent and composition of any permanent structures that would remain within any waterbodies or on land.
The following RAIs (8-13) pertain to the baseline environmental resources that exist in the area where the construction activities may impact the natural and human environment.
RAI-8
The NRC staff requests the licensee to provide an overview of the human and natural environment in the area where the proposed modifications would occur.
RAI-9
The NRC staff requests the licensee to provide a copy of any natural resource studies that have been conducted to characterize the environmental resources on the Oconee Nuclear Station site since publication of the NRCs Generic Environmental Impact Statement for License Renewal of Nuclear Plants: Oconee Nuclear Station, Units 1, 2 & 3 - Final Report (NUREG-1437, Supplement 2) (December 1999).
RAI-10
The NRC staff requests the licensee to describe the occurrence of any known State-or Federally-listed species within or near the Oconee Nuclear Station site.
RAI-11
3 The NRC staff requests the licensee to describe any known cultural resources located within the proposed construction area and on the Oconee Nuclear Station site.
RAI-12
The NRC staff requests the licensee to clarify whether there have been any updates to the Keowee-Toxaway Fishery Resources Ten-Year Work Plan: January 1996-December 2005, that was established between South Carolina Department of Natural Resources and Duke Power Company.
RAI-13
The NRC staff requests the licensee to provide a copy of the following documents, if available: (a) South Carolina Department of Natural Resources and Duke Power Company. 1996. Keowee Toxaway Fishery Resources, Ten Year Work Plan, January 1996-December 2005 (20pp); and (b) the biological survey conducted in June 1998 by Dr. L.L. Gaddy in support of the License Renewal Application for Oconee Nuclear Station.
The following RAIs (14-17) pertain to the extent and intensity of the impacts from the proposed modifications.
RAI-14
The NRC staff requests the licensee to describe the minimum distance between the construction laydown areas to nearby wetlands or other natural areas that were surveyed in 1998 in connection with the Environmental Report for the License Renewal Application for Oconee Nuclear Station.
RAI-15
The NRC staff requests the licensee to describe any measures that will be taken to reduce erosion or run off into aquatic habitats.
RAI-16
The NRC staff requests the licensee to provide a summary description of administrative controls and environmental procedures in place for management of cultural resources ahead of future ground-disturbing activities. The NRC staff also requests the licensee to describe how inadvertent cultural resource discoveries will be treated.
RAI-17
The NRC staff requests the licensee to describe any mitigation measures that the licensee may implement to reduce the environmental impacts from the proposed modifications.
