• Monticello Nuclear Generating Plant

• Prairie Island Nuclear Generating Plant

• Corporate Nuclear Operations / Nuclear Projects

• Summary 2

Human Performance Improvement

• Reason for Independent Assessment

• Timing

• Issue Precursors

- Process Inputs

- Defense in Depth

- Knowledgeable and Experienced Workforce

- Barriers for Excellence/ACEMAN 3

4 Legend MSRC - Management Safety Review Committee NOC - Nuclear Oversight Committee NOS - Nuclear Oversight (QA/QC/ECP) 5

Monticello Nuclear Generating Plant 6

Monticello Nuclear Generating Plant

• Mapping from Assessment to Corrective Action Program (CAP)

• Human Performance (HU) Plan Elements

• Corrective Actions

• Performance Measures

• Results 7

Monticello Nuclear Generating Plant

• Mapping from Assessment to CAP

- Oversight

- Decision Making

- Documentation

- Accountability / Follow-Through

- Learning Organization 8

Monticello Nuclear Generating Plant

• Mapping from Assessment to CAP

- Reviewed current CAP actions in HU

- Matrixed and reviewed by effectiveness

• Learning from the review

- Easier items were completed first as opposed to those potentially more effective

- Risk not thoroughly evaluated

• Asking What if?

• Assessing consequences

• Developing preventive measures

• Planning contingencies 9

Monticello Nuclear Generating Plant

• HU Improvement Plan Elements

- Risk Management

- Management Engagement and Oversight

- HU Performance Fundamentals

- Effective Solutions

- Behaviors 10

Monticello Nuclear Generating Plant

• Corrective Actions

- Learnings/Check and Adjust

• Risk actions target both individual and organizational behaviors

• Resource allocation matching experience

• Coaching versus Observation

• Follow through and rigor to closure of issues

• Integrated plan with accountability 11

Monticello Nuclear Generating Plant

• HU Improvement Plan Corrective Actions

- Communication of revised risk standards and expectations

- Revision of existing processes with added emphasis on risk

- Prioritization of workload / alignment of site resources

- Improved oversight - strengthen use of forcing functions

- Coaching and alignment of standards -- top to bottom

- Long-term resource planning 12

Monticello Nuclear Generating Plant

• Corrective Actions - Defining the Picture of Risk beyond Probabilistic Risk Assessment

- Risk Management Principles

• Nothing is routine

• Take the time to challenge uncertainty

• Risk significant activities will be made visible

• Risk significant activities will be planned, challenged, and controlled

• No Risk option - First Choice

• Prioritization to minimize operational challenges

- Risk Management Behaviors

• Stop / engage when we hear justifications or the word routine

• Methodical fact-based decision making - challenge assumptions

• Risk significant activities are clearly identified with unambiguous owners

• Verify commitments in detail / follow through and validate the specifics 13

Monticello Nuclear Generating Plant

• Corrective Actions

- Integrated decision making

• Risk procedure / expectations for identification and controls

• Protected equipment process - equipment-specific guidance

• Operations pre-shift briefs on risk with barriers/contingencies

- Revitalizing oversight through proven forcing functions

• Restructuring the Corrective Action screening process

• Closure / effectiveness in the Performance Assessment Board

• Dynamic learning exercises to reinforce behaviors 14

Monticello Nuclear Generating Plant

• Corrective Actions

- Reviewing for in-depth preventive contingencies

• Job planning evaluations of risk in work packages

• Projects Challenge Boards with specific plans

• Operational Decision Making for medium and low risk decisions

- Prioritizing work activities and resources

• Support to on-shift crews

• Initial Licensed and non-Licensed Operator classes

• Corrective Action assignments - matching priority with experience

• Protection of core duties 15

Monticello Nuclear Generating Plant

• Performance Measures

- Observation Program trends - risk principles

- Periodic review of past decisions - Plant Operations Review Committee

- Quality of documentation verification / validation

- Event Clock Resets

- Performance during Spring 2009 Refueling Outage

- Day-to-day language change and sensitivity to risk 16

Monticello Nuclear Generating Plant

• Results To Date

- Communication of a risk picture causing change to sensitivity

• Transformer work activities

• Surveillance activities / Control Room alarms

- Work schedules identify risk categories requiring contingencies

- Added controls for oversight to new risk categories

- Validating new procedures at operating locations

- Precursor trends being identified to prevent concerns

- Taking the time needed - slowing down 17

Prairie Island Nuclear Generating Plant 18

Prairie Island Nuclear Generating Plant

• Status of Prairie Island Assessment Report

• Prairie Island Participation in Monticello Plan Development

• Monticello Assessment Applicability to Prairie Island

• Human Performance Plan Development

- Common drivers will use Monticellos Improvement Plan Corrective Actions, if applicable

- Drivers unique to Prairie Island will follow the same methodology used by Monticello 19
