Cumulative Impacts

Overview
• The challenge
• Prioritization
• Regulatory analyses
The Challenge
• Since 2005, the U.S. nuclear industry has seen a
substantial expansion in workload
• The challenge is to ensure management
attention and resources are focused on areas of
highest significance to safety
• More than ever before, NRC and industry need to
work together to weigh, prioritize and implement
regulatory and industry actions in an integrated
manner consistent with safety significance

Main Concerns
• Company-initiated safety, security, and reliability
improvements are squeezed out
- Attention and resources diverted to regulatory needs of
lower safety significance
- Regulatory capital expenditures have increased and are
unstable
• NRC estimates of costs of implementation are off
• Overlapping NRC actions cause rework
Examples of Plant Improvements Deferred
• Improvements to safety injection and feedwater
control systems
• Reactor vessel internal replacements
• Dry-cask fuel storage improvements deferred
because of unclear and evolving NRC requirements
• Improvements in reactor coolant pumps
Addressing Industry-Imposed Actions
• INPO reviewing key processes:
- Corrective action
- Human performance
- Work management
• Understanding the focus of supervisor and
manager workloads and oversight
• Assessing effectiveness of industry initiatives,
committees and organizations
Addressing NRC-Imposed Actions
• NEI offered 24 recommendations to
accelerate, defer, amend or eliminate actions
• Improve regulatory process
- Issue definition and closure criteria
- Regulatory analysis, basis and cost-benefit
analyses
- Prioritization and site-specific scheduling
consistent with safety significance
NRC Activities
• Commissioners’ proposed initiative, Improving
Nuclear Safety and Regulatory Efficiency, using
PRA insights and results to set the regulatory
agenda
• NRC project for addressing cumulative
impact of rulemaking
• NRC-industry working group meetings
12
Initial Scope of Applicability
• Rules and orders
• Bulletins and Generic Letters
- 10 CFR 50.54(f) letters
• New generic safety issues and regulatory
positions
- Described in meeting summaries, correspondence
including inspection reports, regulatory issue
summaries and guidance documents

Provisional Schedule
• Tabletop exercises to test prioritization guidance

• Amend guidance and proceed with pilot field
implementation -- 1Q 2014
• Input into July 2014 NRC SECY on cumulative
impact
• Update guidance for NRC endorsement prior to
industrywide implementation by end of 2014

Case Studies on Variance between
NRC estimates and Implementation Costs
• Studies confirm extreme variance between
NRC estimates and implementation costs
• Determine the causes of the high variance
• Need for better and earlier definition and
implementation characterization
• Industry will need to apply resources earlier to
provide more detailed comments on NRC
estimated costs
Challenges & Issues
• Industry communication and coordination
• Changing cultures
- What is perceived as important to specialist may
be of low relative safety significance
- More robust questioning of new regulatory
positions and requirements
• Disposition of low safety significant issues
Summary
• The number and complexity of new
requirements demands a more integrated
approach to managing plant improvements
• The goal is to do the right things, in the right
order, once
• Industry and NRC must each do their parts to
ensure the public interest in safe, reliable and
economic nuclear energy is served
