APPENDIX E Applicant’s Environmental Report Operating License Renewal Stage Grand Gulf Nuclear Station Grand Gulf Nuclear Station Applicant’s Environmental Report Operating License Renewal Stage INTRODUCTION System Energy Resources, Inc., South Mississippi Electric Power Association, and Entergy Operations, Inc. (hereafter referred to as "Entergy"), submit this Environmental Report (ER) in conjunction with the application to the United States Nuclear Regulatory Commission (USNRC) to renew the operating license for Grand Gulf Nuclear Station Unit 1 (hereafter referred to as GGNS or GGNS Unit 1) for twenty (20) years beyond the end of the current license term. In compliance with applicable USNRC requirements, this ER analyzes potential environmental impacts associated with renewal of the GGNS Operating License (OL). This ER is designed to assist the USNRC staff with the preparation of the GGNS specific Supplemental Environmental Impact Statement (SEIS) required for license renewal. The GGNS ER is provided in accordance with 10 CFR 54.23, which requires license renewal applicants to submit a supplement to the ER that complies with the requirements of Subpart A of 10 CFR Part 51. This report also addresses the more detailed requirements of NRC environmental regulations in 10 CFR 51.45 and 10 CFR 51.53(c), as well as the intent of the National Environmental Policy Act (NEPA), 42 USC 4321 et seq. For major federal actions, NEPA requires federal agencies to prepare a detailed statement that evaluates environmental impacts, alternatives to the proposed action, and irreversible and irretrievable commitments of resources associated with implementation of the proposed action. Entergy used Supplement 1 to Regulatory Guide 4.2, "Preparation of Supplemental Environmental Reports for Applications to Renew Nuclear Power Plant Operating Licenses," as guidance on the format and content of this ER. In addition, Entergy utilized the Generic Environmental Impact Statement (GEIS) for License Renewal of Nuclear Plants (NUREG-1437) and Appendix B to 10 CFR Part 51 in preparation of this report. The level of information provided on the various topics and issues in this ER are commensurate with the environmental significance of the particular topic or issue. Based upon the evaluations discussed in this ER, Entergy concludes that the environmental impacts associated with renewal of the GGNS OL are SMALL. No plant refurbishment activities have been identified as necessary to support the continued operation of GGNS beyond the end of the existing operating license term. Ongoing plant operational and maintenance activities will be performed during the license renewal period, but no significant environmental impacts associated with such activities are expected since established programs and procedures are in place to ensure that proper environmental monitoring continues to be conducted throughout the renewal term as discussed in Chapter 9. ii Grand Gulf Nuclear Station Applicant’s Environmental Report Operating License Renewal Stage ACRONYMS AND ABBREVIATIONS UNITS OF MEASURE ~approximately $ dollars º degrees '' inches 'feet % percent > is greater than < is less than < is less than or equal to Btu British thermal units ºC degrees Centigrade Ceq/kWh carbon equivalents per kilowatt hour cfs cubic feet per second cm centimeter cm/sec centimeters per second cm2 square centimeters dBA decibels, A scale ºF degrees Fahrenheit ft feet ft2 square feet ft3 cubic feet gpm gallons per minute ggrams gpd gallons per day gpd/ft gallons per day per foot iii Grand Gulf Nuclear Station Applicant’s Environmental Report Operating License Renewal Stage ACRONYMS AND ABBREVIATIONS (CONTINUED) GW gigawatt hr hour kv kilovolts kW kilowatt kWh kilowatt-hour kWh/m2 kilowatt hour per square meter lb pound m meter m2 square meter m3 cubic meter m3/s cubic meters per second µmicrons µm micrometer µmho/cm micromhos per centimeter mA milliAmp mgd million gallons per day mg/l milligrams per liter mGy milli-Gray mi miles mi2 square miles ml milliliter MMBtu million British thermal units mrad millirad mrem millirem m/s meters per second MSL mean sea level iv Grand Gulf Nuclear Station Applicant’s Environmental Report Operating License Renewal Stage ACRONYMS AND ABBREVIATIONS (CONTINUED) mSv milli-Sievert MW megawatts MWd/MTU megawatt-days per metric tonne MWe megawatts, electric MWh megawatt-hours MWt megawatts, thermal pCi/l picocuries per liter RM river mile sec second SU standard units tpy tons per year watt-hr/m2/day watt-hour per meter squared per day yr year ACRONYMS/ABBREVIATIONS ALARA as low as reasonably achievable ARCS Advanced Resin Cleaning Subsystem ASU Alcorn State University BWR Boiling Water Reactor CAA Clean Air Act CAES compressed air energy storage CaO calcium oxide CaSO4*2H2O calcium sulfate dehydrate CEQ Council on Environmental Quality CERCLA Comprehensive Environmental Response, Compensation and Liability Act CET containment event tree v Grand Gulf Nuclear Station Applicant’s Environmental Report Operating License Renewal Stage ACRONYMS AND ABBREVIATIONS (CONTINUED) CDF core damage frequency CFR Code of Federal Regulations CH4 methane CO carbon monoxide CO2 carbon dioxide COL Combined Operating License COLA Combined Operating License Application CST Condensate Storage Tank CWA Clean Water Act CWS Circulating Water System DSM demand side management EAB Exclusion Area Boundary ECCS emergency core cooling systems EEI Edison Electric Institute EHV extra high voltage EIA Energy Information Administration EMI Entergy Mississippi, Inc.
