USNRC Engineering Inspection Review Engineering Inspection ReviewObjectiveDiscuss recommendations of Engineering Inspection Working Group with stakeholders and seek feedback 2

Engineering Inspection Review 3Principal Considerations

-Consider stakeholder input-Increase or maintain effectiveness

-Independent oversight

-Identification of latent conditions

-Increase relevance to current challenges Engineering Inspection ReviewPrincipal Considerations (Cont'd.)

-Increase efficiency

-Eliminate overlap-Capture advantages of holistic inspection of engineering design changes-Knowledge gained from inspection experience

-18+ years-Value of independent inspection

-Credible assessment of plant design 4

Engineering Inspection Review 5Overall Results

-Conduct independent NRC engineering inspections annually

-New suite of engineering inspection procedures

-Holistic, agile, flexible, relevant

-Reduced overlaps and addressed gaps

-Maintain reasonable assurance of safety 6Engineering Inspection ReviewCurrent Engineering Inspections (Triennial Period)DBAI - Team Inspection BI: 312 Hours Resources: 4 Inspectors

Engineering Inspection ReviewFuture Engineering Inspections

-Identify if latent design issues are introduced through design changes

-Verify SSCs continue to be capable of performing as designed through a emphasis on more relevant areas (aging, obsolescence, etc.)

-Verify changes do not introduce new or increased frequency of initiating events 8

Engineering Inspection ReviewComprehensive Engineering Team Inspection (CETI)

-Emphasize inspection on changes, operating experience, and aging

-Incorporates elements of modifications, 10CFR50.59, and DBAI inspections

-Team makeup of five inspectors with one or two contractors for two onsite weeks 9

Engineering Inspection ReviewFocused Engineering Inspection (FEI)

-Independent inspection of specific engineering activities

-Areas may be identified with stakeholder input, selected by NRC

-Risk insights and operating experience considered10 Engineering Inspection ReviewFEI (Cont'd)

-Nominally three inspectors for two onsite weeks depending on inspection (focus area dependent)

In-Service Inspection

-Added periodic oversight of 10

-year program implementation

-Continue inspections during outages 11 Engineering Inspection ReviewResource ImplicationsOverall reduction in annualized baseline inspection and associated prep/doc12Current 3 Year CycleProposed 4 Year CycleTotal Number of Inspections7 Inspections6 InspectionsAnnual Onsite Weeks3.66weeks/yr(11 onsite weeks)2.75weeks/yr(11 onsite weeks)AverageInspection Hours per Year293 Hours245 Hours Engineering Inspection ReviewImproved safety inspections

-Annual independent NRC engineering inspections

-New suite of engineering inspection procedures

• Holistic, agile, flexible, relevant

• Reduced overlaps and addressed gaps

-Maintain reasonable assurance of safety13 Engineering Inspection ReviewRecap of EIWG RecommendationsImplement changes to engineering inspections Increased effectivenessIncreased efficiencyIncreased agilityIncreased relevance14 Engineering Inspection ReviewRecap of EIWG Recommendations (Continued)Reduce types of inspections from 6 to 3Increase inspection cycle from 3 years to 4 yearsImplementation Timeline ConsiderationsImmediate?2019?2020?15 Future ConsiderationsLicensee Self Assessments Engineering Inspection ReviewEIWG Recommendations

• Continue dialog on self

-assessments

• Industry develop self

-assessment standard

• Consider implementation of a project demonstration with independent NRC oversight

• Establish criteria for use (e.g., licensee in Column 1 for three consecutive years?)

• Establish limitations on use17 Engineering Inspection ReviewSelf Assessment Standard

-Proposed by industry and reviewed/approved or endorsed by NRC

-Must address

• Independence

• Clarity and Reliability (self

-critical)*Openness*Efficiency18 Engineering Inspection ReviewProject Demonstration

-Using the industry

-developed standard

-NRC to provide oversight

-Select same area as FEI

-Compare self

-assessment results with NRC independent inspection19 Engineering Inspection ReviewChallenges

-Industry development of a self

-assessment standard-NRC guidance for review of self

-assessment

-Findings, transparency, and other issues20 Engineering Inspection ReviewSelf Assessment Considerations21 Comprehensive Engineering Team Inspection BI: 350 Hours Resources: 5 Inspectors
