Preliminary Results of Environmental Review Arkansas Nuclear One, Unit 2 Nuclear Regulatory Commission October 21, 2004
Purpose of Todays Meeting 3/4 Discuss NRCs license renewal process 3/4 Describe the environmental review process 3/4 Discuss the results of our review 3/4 Provide the review schedule 3/4 Accept any comments you may have today 3/4 Describe how to submit comments 2
Arkansas Nuclear One, Unit 2 License Renewal Application 3/4 Current operating license expires 07/17/2018 3/4 Requests authorization to operate Arkansas Nuclear One, Unit 2 for up to an additional 20 years 3
NRCs License Renewal Review 3/4 Safety review 3/4 Environmental review 3/4 Plant inspections 3/4 Advisory Committee on Reactor Safeguards (ACRS) 4
License Renewal Process Onsite Inspection Inspection Activities Report ACRS ACRS Review Report Safety Review Safety Safety Evaluation Review Report License Renewal Agency Application Hearings* Decision on Application Environmental Scoping Draft Comments Final Review Activities Supplement On Draft Supplement To GEIS To GEIS Formal Public *If a request for hearing is granted Participation 5
National Environmental Policy Act 3/4 NEPA requires Federal agencies to use a systematic approach to consider environmental impacts 3/4 Commission has determined that an environmental impact statement (EIS) will be prepared for a license renewal action 6
Decision Standard for Environmental Review To determine whether or not the adverse environmental impacts of license renewal for ANO, Unit 2 are so great that preserving the option of license renewal for energy planning decisionmakers would be unreasonable.

NO NO Adopt the No Further GEIS Conclusion Analysis 10
How Impacts are Quantified 3/4 NRC-defined impact levels:
3/4 SMALL: Effect is not detectable or too small to destabilize or noticeably alter any important attribute of the resource 3/4 MODERATE: Effect is sufficient to alter noticeably, but not destabilize important attributes of the resource 3/4 LARGE: Effect is clearly noticeable and sufficient to destabilize important attributes of the resource 3/4 Consistent with the Council on Environmental Quality guidance for NEPA analyses 11

Threatened or Endangered Species 19
Threatened or Endangered Species 3/4 Myotis grisescens, gray bat 3/4 Haliaeetus leucocephalus, bald eagle 3/4 Sterna antillarum, least tern 3/4 Notropis girardi, Arkansas River shiner 20
Cumulative Impacts of Operation 3/4 Considered impacts of renewal term operations combined with other past, present, and reasonably foreseeable future actions 3/4 evaluated to end of 20-year renewal term 3/4 geographic boundaries dependent on resource 3/4 No significant cumulative impacts 21
Other Environmental Impacts Evaluated 3/4 Uranium Fuel Cycle and Solid Waste Management 3/4 Decommissioning 22
Alternatives 3/4 No-action 3/4 Alternative energy sources 3/4 New generation (Coal, Natural Gas, Nuclear) 3/4 Purchased electrical power 3/4 Other alternatives (Oil, Wind, Solar, Conservation) 3/4 Combination of alternatives 3/4 Environmental effects of alternatives in at least some impact categories reach MODERATE or LARGE significance 23
Analysis Approach Generic Environmental Impact Statement (GEIS)

Preliminary Conclusions 3/4 GEIS Conclusions on Category 1 issues adopted.
3/4 Impacts resulting from Category 2 issues are of SMALL significance.
3/4 No new impacts identified.
3/4 Environmental effects of alternatives may reach MODERATE or LARGE significance.
25
Postulated Accidents 3/4 Design-basis accidents 3/4 Severe accidents 3/4 Severe accident mitigation alternatives (SAMAs) 26
SAMA Evaluation Process 3/4 Characterize overall plant risk 3/4 Identify potential improvements 3/4 Quantify risk reduction potential and implementation costs 3/4 Determine whether implementation of any of the improvements is required to support license renewal 27
Preliminary Results of SAMA Evaluation 3/4 192 candidate improvements considered 3/4 Set of SAMAs reduced to 93 based on multi-step screening process 3/4 Detailed cost/benefit analysis 3/4 2 procedural SAMAs potentially cost beneficial 3/4 2 SAMAs related to diversity of equipment could be cost beneficial 28
Preliminary Results of SAMA Evaluation 3/4 Potential cost-beneficial SAMAs not related to managing the effects of aging 3/4 Not required to be implemented as part of license renewal 29
Preliminary Conclusions 3/4 Impacts of license renewal are SMALL for all impact areas 3/4 Impacts of alternatives to license renewal range from SMALL to LARGE 3/4 The staffs preliminary recommendation is that the adverse environmental impacts of license renewal for ANO-2 are not so great that preserving the option of license renewal for energy planning decisionmakers would be unreasonable 30
