Presentation Overview Mission statement for the Center for Construction Inspection (CCI)

CCI organizational structure Inspection program structure Vogtle Construction Related Inspection Activities CCI Staffing

Mission Statement To provide assurance in the safety of future operations at new nuclear facilities by ensuring that licensees and applicants construct the facilities according to approved design criteria, using appropriate practices and quality materials

Organization Structure Two divisions Division of Construction Projects (DCP)

Project management for each construction site Oversees completion of inspection program Manages the resident inspector program Division of Construction Inspection (DCI)

Regional resources for conducting inspections Specialists in various engineering fields Contacts for technical issues

Inspection Program Structure ITAAC inspections (IMC 2503)

Verifies that sampled design commitments associated with the license and their acceptance criteria are met prior to fuel load Non-ITAAC inspections (IMC 2504)

Verifies that programs associated with construction and operation are effective and meet the regulations

What are ITAAC?

Inspections, tests, analyses and acceptance criteria (ITAAC)

ITAAC are design commitments that are defined during the NRC combined license application review and/or reactor design certifications ITAAC define the method the license holder will use to verify the design commitment has been met And it defines the methods acceptance criteria After the start of construction and prior to fuel load the license holder shall verify all ITAAC have been met

Non-ITAAC Inspections (examples)

Construction programs Quality assurance Reporting defects and non-compliance Fitness for duty Pre-operational Testing Operational programs In-service inspection Reactor operator training Operational readiness

Limited Work Authorization LWA approved in August 2009 Allows placement of engineered backfill, retaining walls, lean concrete, mudmats, and a waterproof membrane Additional LWA request (Oct. 2009) under review to allow rebar, concrete and buried items for nuclear island basemat Combined License Review scheduled for completion in 2011

Recently Completed Activities Lake Charles Site Visit - Mock-up Module Fitness For Duty Inspection

Inspection Staffing Regional Started CCI in 2006, steadily increased staff levels since then based on projected number of reactor projects Resident Posted first senior resident position application in anticipation of construction at the Vogtle Project Plan to fill position sometime in 2010

Closing Remarks Inspection Program started in November 2009 Inspection Program for 2010 is planned Staffing will increase as the workload increases Continue to protect the publics health and safety by overseeing construction of new nuclear reactors
