ENCLOSURE 2 NORTH ANNA POWER STATION, UNITS 1 AND 2 LICENSE RENEWAL ENVIRONMENTAL AUDIT NEEDS LIST Please be prepared to discuss the following issues and make the following available during the environmental site audit.
Questions, Document Needs, and Breakout Sessions Specific questions and document needs are provided below by resource area. In addition, please provide for breakout meeting sessions using Microsoft Team with the subject matter expert(s) and/or the contractor(s) responsible for the following topics who can also discuss the corresponding information requests, as described below. The staff uses these meeting sessions as needed to resolve or clarify any outstanding data needs or questions arising from the environmental audit.
Audit Needs:
Alternatives ALT-1 Section E.2.6 of the ER indicates that no action regarding license renewal of NAPS would require the consideration of 1,672 MWe of replacement power. This value appears to be used for the basis of the alternative analyses presented in ER Sections E.7 and E.8. However, other sources reviewed by NRC suggest that the total replacement power value for NAPS should be closer to 1,892 MWe. Please clarify the basis for the replacement power value(s) presented in the NAPS ER.
Aquatic A-1 Section E3.7.7, Studies and Monitoring, of the ER describes a semi-annual sampling program to monitor Asiatic clams in the reservoir. Please provide copies for NRC staff review of results or any reports associated with this sampling program for the past 5 years.
A-2 The ER references annual reports titled, Environmental Study of Lake Anna, Waste Heat Treatment Facility and the Lower North Anna River, through 2018. Are more recent reports now available (i.e., 2019 or 2020)? If so, please provide copies of these reports for NRC staff review.
A-2 (A-3) The ER describes several aquatic studies and monitoring programs in connection with NAPS. Is Dominion aware of any other aquatic studies or monitoring not associated with NAPS that are occurring in Lake Anna Reservoir or in the Lake Anna River near NAPS? For instance, such monitoring could include initiatives by the U.S. Army Corps of Engineers, conservation-focused organizations, or other Federal, State, or private entities.
Cumulative Impacts CI-1 Please provide name, description, location, and status of any additional past, present, or reasonably foreseeable projects or actions that have been identified since the ER was prepared.
Groundwater GW-1 Some hyperlinks in the reference list are no longer accessible. Please provide updated and accessible links for these references and update the ER reference list with these new links.
GW-2 Table footnote contains gpd but gpd is not used in table. Please confirm/correct text in table and/or footnotes.
Enclosure 2
GW-3 In the ER, Actions are ongoing to investigate and mitigate potential tritium pathways to ground in the area of GWP-18.
(a) Please provide as-built information on the Mat sumps including the U-1 Mat Sump East sump and locations of other sumps relative to elevations of residual soils, fractured subsurface bedrock and groundwater levels.
(b) Please include a description of any ongoing or completed remediation actions and the residual activity remaining after the remediation was completed, if it is not ongoing and, any additional actions taken related to characterize elevated 2019 tritium concentrations in GWP-3, GWP-18 and the U-1 Mat Sump East.
(c) GWP-18 is screened in the fractured rock (Haley and Aldrich, 2015). This zone is noted as a preferred groundwater pathway. Please provide information on any additional tritium detections downgradient of GWP-18 in bedrock and soil and, characterization of the hydraulic connection of the U-1 Mat Sump East and the groundwater flow system.
(d) Please provide information on the likely tritium sources and the presence of boron in the 2019 groundwater sampling results and, characterize the significance of boron if present.
(e) Is the water sampled from theU-1 Mat Sump East considered to be groundwater?
If so, has the State of Virginia been notified of the tritium groundwater standard exceedance (i.e., 20,000 pCi/L) for the 2019 sampling period?
GW-4 NAPS 2019 groundwater sampling results note that Increased tritium concentrations are due to the draining of 1-SI-P-1B to the Unit 1 Safeguards Valve Pit. 1-SI-P-1B was drained to the U-1 Safeguards Valve pit due to 1-DA-P-lA/1B Safeguards Sump pumps being out of service. Tritium in the U-1 East Mat Sump was released as liquid effluent via the station liquid waste system.
(a) Please characterize the effluent quality drained from 1-SI-P-1B.
(b) Please provide as-built information and map locations of the U-1 Safeguards Valve pit relative to groundwater levels and the groundwater flow system and, any information related to the interaction of water levels in the pit to groundwater levels.
(c) Is the U1B Mat Sump (Haley and Aldrich, 2015) also known as the U-1 Sump East sump as listed in the NAPS Radiological Environmental Monitoring Program (REMP) reports? If not, which sump in the Haley and Aldrich report is also known as the U-1 Mat Sump East as referred to in the REMP reports?
(d) Please provide a map that includes site features and legible labels for all sampling locations listed in Attachment 8, "RESULTS OF GROUND WATER PROTECTION INITIATIVE SAMPLE ANALYSIS" within the REMP report.
GW-5 Based on groundwater level contour patterns as characterized in the Haley and Aldrich (2015), page 37, the Pipe Tunnel appears to be losing (contributing) water to the groundwater flow system.
(a) Please provide information on the as-built characteristics of the tunnel with respect to groundwater table levels and the surrounding soils and bedrock.
(b) Please characterize the effluent within the pipes of the Pipe Tunnel with respect to elevated 2019 tritium groundwater concentrations.
(c) Please identify any aliases within the ER for the Pipe Tunnel as identified in Haley and Aldrich (2015).
(d) Please provide information or documented investigations that characterize hydraulic connection of the potential Pipe Tunnel leakage with the groundwater flow system and the influence of potential tunnel leakage on the flow system.
(e) Please identify any recent investigations that further characterize the historical tritium sources releasing to the groundwater system that emanate from small lenses both above the water table in the vadose zone and below the water table as described in Haley and Aldrich (2015).
(f) Please comment on the precipitation during time frame of 2019 REMP sampling and any potential relationship to the elevated tritium sampling data for 2019 from sources in the small lenses given the relatively wet period in the 4th quarter of 2019.
GW-6 In the ER, No unplanned radioactive liquid releases were reported between 2012 and 2019. Other areas of ER indicate no unplanned releases 2012 and 2017 (e.g., Table E6.1-1 Environmental Impacts Related to SLR at NAPS; SMALL impact. No unplanned radioactive liquid releases were reported between 2012 and 2017.)
(a) Please provide the rationale for the statement in Table E8.0-3, Page E-8-12 of No unplanned radioactive liquid releases were reported between 2012 and 2019 and including different periods time elsewhere in the ER.
(b) Please provide the rationale for not including the more recent 2018 or 2019 sampling data regarding unplanned releases in the ER and identify any updates to the ER that may be needed for inclusion of the 2019 sampling data.
GW-7 In the ER, Based on the review of site records from the seven years from 2013-2019, there has been no inadvertent nonradioactive release that would not be classified as an incidental spill as defined by OSHA. This statement appears to be inconsistent with the reporting period in the previous paragraph in Section E3.6.4.2.1 History of Radioactive Releases which states that No unplanned radioactive liquid releases were reported between 2012 and 2019. Please account for the potential inconsistency in these two reporting periods here and elsewhere in the ER.
