SUMMARY

OF FINDINGS A. Inspector-Identified and Self-Revealingi Findings None B. Licensee-Identified Violations None

4OA5 Other Activities

.1 Unit 3 Steam Generator Replacement Inspection (IP 50001)

a. Inspection Scope Design and Planning The inspectors reviewed the following related to the licensee's steam generator replacement (SGR) project design and planning:
  • scope and schedule
  • Engineering Change (EC) packages
  • Quality Assurance Program and corrective actions
  • preparations for the creation of a temporary containment wall opening
  • applicable engineering design, modification, and analysis associated with lifting, rigging, and transporting of the steam generators (SGs) 0 radiation protection program controls, planning, and preparation
  • security considerations associated with vital and protected area barriers affected by the SGR activities
  • controls to minimize any adverse impact the activities may have had on other systems.

The licensee used ASME Boiler and Pressure Vessel Code (ASME Code)Section III, 1998 Edition through 2000 Addenda, and Section XI, 2001 Edition through 2003 Addenda, for the design, fabrication, replacement, and installation of the new replacement SGs (RSGs) and systems. The licensee used ASME Code Section III for the design, fabrication, installation, and Nondestructive Examination (NDE) as the construction code for the following major component modifications: Reactor Cooling System (RCS) Primary Piping Connections; Main Steam, Feedwater, and Emergency Feedwater Piping Connections; and the Steel Containment Vessel. The inspectors reviewed and examined the SGR activities and compared them to the requirements of the ASME Code.

The inspectors reviewed EC 63038, Replacement Once Through Steam Generators (ROTSGs or RSGs), for Crystal River Unit 3. The EC 63038 included the design changes, analyses, evaluations, safety analyses, 10 CFR Part 50.59 Change Evaluation, configuration, materials, implementation, and post modification testing acceptance. The inspectors reviewed the following other major modification packages: EC 62500, RCS Hot Leg Cutting and Welding; EC 63016, Containment Opening; EC 63025, Main Feedwater Flow Accelerated Corrosion (FAC) Pipe Replacement; EC 63026, RCS Cold Leg Cutting and Welding; EC 63027, Secondary Side Large Bore Pipe Cutting and Welding; EC 63034, Structural Interferences; and EC 63039 Replacement Steam Generator Anchorage. The inspectors also reviewed other miscellaneous and temporary modifications.

1' The inspectors reviewed design calculations and analyses for design methods, assumptions, loadings, computations, and accuracies. The inspectors also selected work order (WO) packages prepared for the construction and implementation of the ECs for review to determine whether appropriate work processes and quality control hold points were implemented.

The inspectors reviewed the licensee's screening of selected ECs to determine whether the modifications were evaluated in accordance with 10 CFR Part 50.59, "Changes, tests, and experiments."

Removal and Replacement The inspectors periodically reviewed radiation controls. The inspectors verified that the tendons were removed after shutdown and prior to the hydro demolition of concrete for the containment building wall opening located above the equipment hatch in order to transport the SGs out from or into the containment. The inspectors observed the hydro demolition process. The licensee identified some concrete cracks/separation issues.

The concrete separations could be seen within the entire perimeter of the opening. An NRC Special Inspection Team (SIT) was formed to inspect the separation issues. The SIT's charter included review of the evaluation, root cause, and corrective actions to be implemented to ensure an operable containment structure. The SIT remained ongoing at the end of this inspection period.

The inspectors reviewed the cracks or delamination found on the exposed concrete around the containment building wall opening during and after the hydro demolition. The licensee evaluated the containment wall cracks to adjust Horizontal Transfer System (HTS) supporting structures. Prior to the removal of the original or old SGs (OSGs), the inspectors reviewed, observed, and evaluated the associated temporary and permanent modifications of the cutting, disconnecting, and the providing of temporary supports for the OSGs and cutoff piping. The inspectors observed: lifting, rigging, downending or upending, and transporting of the OSGs, RSGs, and associated equipment; machining and preparations of the existing piping for the connections to the RSGs; welding and NDE activities; and the radiological safety plan for the temporary storage and disposal building of the retired steam generators. The inspectors reviewed and observed the major structural modifications. The inspectors observed the licensee perform inspection of the steam generator hold down bolts to make sure that the bolts were acceptable to hold down the RSGs after the OSGs were moved out from the cubicles. During the SG removal and replacement, the inspectors observed licensee activities associated with controls for excluding foreign material, including the primary and secondary side of the steam generators and in the related RCS openings, and the establishment of operating conditions including defueling, RCS draindown and system isolation. The inspectors reviewed and inspected the status of security activities associated with vital and protected area plant or equipment changes required for the transportation of the OSGs and RSGs. The inspectors reviewed the installation, use, and removal of temporary services directly related to the steam generator replacement activities.

The inspectors observed and reviewed selected welding, NDE, preservice inspections, baseline inspections, and corrective action activities for the Class 1 and 2 piping and components of the RSGs.

The inspectors reviewed procedures, examination results, modification packages, and work order packages related to the modifications, including the construction hatch steel containment vessel (SCV) reinstallation, to ensure compliance with the requirements of the ASME Code.

This inspection remained ongoing at the end of this inspection period because the closure of the containment wall opening was not completed due to the cracks or delamination identified on the containment wall.

RSG Fabrication, Preservice Inspection, and Baseline Inspection The inspectors reviewed records associated with the materials, fabrication, examination, and testing for the RSGs manufactured by Babcock & Wilcox Canada (BWC), and replacement hot leg piping subassemblies ("Candy Canes"), to verify compliance with the ASME Code.

The inspectors reviewed records and conducted interviews with appropriate plant personnel associated with the following RSG welds:

" W-22 (ASME Class 1, Lower Head to Lower Tubesheet Weld)

" W-65 (ASME Class 2, Lower Head to Shell Can #1)

  • W-415 (Seal Weld Tube to Tubesheet Cladding)

The inspectors reviewed records associated with: Certified Material Tests; materials NDE, weld preparation, weld preheat treatment and post weld heat treatment, hydrostatic testing, and preservice inspection (post hydrostatic testing); ASME Certificates of Accreditation and Authorization; weld material qualification; weld control sheet and welder's records; and nonconformance reports. Other documentation reviewed included ASME Data Reports, ASME Design Specification, ASME Design Reports, and ASME repair/replacement documentation reconciliation of items, and the associated Engineering Change packages. The inspectors also walked down one RSG while stored on site, prior to movement into containment.

The inspectors reviewed documentation and interviewed plant personnel regarding the preservice and baseline testing of RSG tubing. All Preservice Inspection (PSI) or Baseline Inspection (BI) using Eddy Current Testing (ECT) for the RSG tubes was completed off-site by BWC in Cambridge, Ontario, Canada. Full length 100 percent bobbin inspections were performed, and 100 percent X-probe data was acquired, but only analyzed in areas of interest. Profilometry data was also collected in the tubesheet expansion region. The inspectors reviewed the licensee's Degradation Assessment, BWC ECT PSI report, ECT acquisition procedures, examination technique specification sheets, and data analysis procedures. In addition, the inspectors reviewed documentation regarding the manufacture of the RSG tubing by Sumitomo in Japan including heat treatment records and nonconformance reports.

f' The inspectors reviewed records and conducted interviews with plant personnel associated with the fabrication of the replacement hot leg piping subassemblies.

Documents reviewed included the ASME Data Report, corrective action documents, the vendor ASME Certificate of Authorization, a self-assessment report, and the Engineering Change package. The inspectors also walked down both replacement hot leg piping subassemblies while stored on site, prior to movement into containment.

Weldinq The inspectors reviewed a sample of welding activities associated with the installation of the RSGs to evaluate compliance with licensee/contractor procedures and the applicable ASME Code. The inspectors reviewed joint configuration drawings, welding procedures, welding specifications, welding procedure qualifications, welder qualification records, weld data records, Nuclear Condition Reports (NCRs), and post weld heat treatment procedures (where applicable) for the welds listed below.

  • MS-00-034, SG A Main Steam West Elbow-to-Pipe In addition to the record review described above, the inspectors performed field observations either via video monitors located outside containment or by direct observation inside containment of the machine welding of the RCS hot leg and cold leg piping welds listed below.

  • MS-00-045, SG B Main Steam East Pipe-to-Pipe Containment Construction Hatch Opening and Closure - Steel and Concrete Containment The inspectors reviewed the licensee's activities associated with the concrete renmoval and the removal and restoration of the steel containment liner plate (SCLP) for the

containment construction hatch opening, as detailed in the EC 63016, Containment Opening.

The inspectors reviewed the plans for the cutting and restoration of the SCLP for the construction hatch opening and compared post testing requirements to the applicable ASME Code. The inspectors observed the hydraulic cutting, hydro demolition, of concrete for the containment construction hatch opening and reviewed the work order packages for the cutting to verify the steps had been completed and documented.

The inspectors reviewed the welding procedures, procedure qualification records, and welder qualification records to confirm that the Code-required essential and supplemental essential welding variables were met. The inspectors reviewed the work order package including welding electrode receipt inspection, vacuum box leak testing, MT records, material certification records, and qualification and certification records for NDE personnel, equipment, and consumables.

The inspectors reviewed containment wall delaminations that were found next to the Hoop or Horizontal Tendons about 10 inches from the outside surface of the containment wall. The delaminations were identified on the exposed concrete wall surfaces around the opening of containment during and after the hydro demolition for the opening. The inspectors observed the licensee perform sonar impulse response examination as an NDE method to detect and scope the delamination areas.

The licensee planned to address the closure of the containment wall opening as part of the repair of the containment wall delamination.

Heavy Load, Rigqging, Lifting, and Transporting Activities The inspectors reviewed Progress Energy administrative procedures MNT-NGGC-0005, Control of Rigging and Temporary Loads, Revision 3 and Crystal River AL-650, Rigging, Lifting, and Material Handling Program, Revision 5. The inspectors reviewed the SG lifting preparation activities as described in the following EC Packages and Lifting Equipment Load Test Data to ensure that they were prepared in accordance with regulatory requirements, appropriate industrial codes and standards, and to verify that the maximum anticipated loads to be lifted would not exceed the capacity of the lifting equipment and supporting structures: EC 63020, Outside Erection Crane and Inside Auxiliary Crane, Revision 7; EC 63022, Steam Generator Rigging and Transport including the Outside Lift System (OLS), Hatch Transfer System (HTS), and Temporary Lifting Device (TLD), Revision 31; and EC 63023, OSG/RSG Haul Route, Revision 3.

The inspectors examined SGR project lifting, rigging, and transporting equipment including the polar crane, mobile crane, TLD, HTS including skid system, the down/up-ender device, OLS, and the Self-Propelled Modular Transporter (SPMT). The inspectors observed portions of rigging, lifting, transportation, and positioning of the original and replacement SGs.

The inspectors reviewed procedures, calculations, drawings, work packages, crane and equipment operator training and certificates, and load and function test records to determine whether they were in accordance with regulatory requirements and appropriate industrial codes and standards. The inspectors also reviewed polar crane and Containerized Winch System inspection and maintenance records.

The inspectors reviewed the licensee's analyses for buried piping located beneath the transport path as documented in Calculation S06-0019, Evaluation of Buried Utilities under Haul Route, Revision 0. The inspectors also reviewed calculations related to heavy load lifting systems, including: S06-0009, TLD Loads on Polar Crane Rail, Revision 0; S06-0012, Outside Lifting System East Foundation Design, Revision 3; and S06-0015, Seawater Room Wall Evaluation, Revision 1.

Quality Assurance (QA) Proqram and Corrective Actions The inspectors conducted a review of the Quality Assurance Program and its implementation for the SG replacement to assess compliance with the requirements of 10 CFR Part 50, Appendix B. The inspectors reviewed Daily Quality Summaries, quarterly reports, QA audit procedures, audit reports, and QA personnel certifications, and conducted interviews with QA/QC personnel.

The inspectors reviewed the licensee's corrective action program (CAP). The inspectors reviewed the surveillance reports and nonconformance reports issued for the root cause analyses, evaluations, repairs, or disposition during the manufacturing of the RSGs. The inspectors also selected the Nuclear Condition Reports (NCRs) and Audit Reports for review during the implementation of the removal and reinstallation of the SGs. The review was to ensure that issues were being identified appropriately, entered into the CAP correctly, and dispositioned adequately. The inspectors also reviewed procedures associated with the training of personnel for the identification, disposition, and documentation of the NCRs.

Post Installation Verification and Testing The inspectors reviewed the post installation verification and testing program to verify that the required post installation verification and testing', procedural changes, and the adjustment of the instruments were properly identified. The inspectors verified the modifications were completed in accordance with the design documents and reviewed the required post modification tests.

The inspectors reviewed the work packages to verify that the required NDE and preservice inspections were completed as designed and met code requirements for the major modifications of the SGs, structures, and piping.

The post modification or installation verification and testing related to RCS leakage testing, containment pressure leak testing, SG thermal and hydraulic performance testing, other instrument setting or testing were not completed during this quarter because the installation of the containment construction hatch opening closure and the

repair of the containment wall delaminations were delayed to the next year. Additionally, steam generator secondary side leakage testing had not been completed by the licensee at the conclusion of this inspection period.

All documents reviewed for IP 50001 are listed in the attachment to this report.
