11) A report exists and concludes that the as-built Class 1E equipment and the associated wiring, cables, and terminations identified in Table 2.1.3-1 as being qualified for a harsh environment are bounded by type tests, analyses, or a combination of type tests and analyses.

ITAAC Completion Description This ITAAC requires that inspections, tests, and analyses be performed and documented to ensure the Reactor System (RXS)components identified as seismic Category I or Class 1E in the Combined License(COL)Appendix C, Table 2.1.3-1 (the Table) are designed and constructed in accordance with applicable requirements.

i) The seismic Cateaorv I equipment identified in Table 2.1.3-1 (except fuel assemblies, rod cluster control assemblies, orav rod cluster assemblies, and incore instrument QuickLoc assemblies) is located on the Nuclear Island.

To assure that seismic Category I components can withstand seismic design basis loads without loss of safety function, all the components in the Table are designed to be located on the seismic Category I Nuclear Island. In accordance with Equipment Qualification (EG)

Walkdown ITAAC Guideline and EG ITAAC As-built Installation Documentation Guideline (References 1 & 2), an inspection is conducted of the RXS to confirm the satisfactory installation of the seismically qualified components. The inspection includes verification of equipment make/model/serial number and verification of equipment location (Building, Elevation, Room).

Fuel assemblies, rod cluster control assemblies, gray rod cluster assemblies, and incore instrument QuickLoc assemblies are not installed in their final location until after the 10 CFR 52.103(g)finding has been made as part of initial fuel load. Per item ii below, the assemblies are seismically qualified when located on the nuclear island. Inspections of these assemblies are performed but not in the final installed location, since that is not allowed by 52.103(g). The EG As-Built Reconciliation Reports(EQRR)(Reference 7) identified in Attachment A document the results of the inspection and conclude that the seismic Category I components are located on the Nuclear Island except for the fuel assemblies, rod cluster control assemblies, gray rod cluster assemblies, and incore instrument QuickLoc assemblies.

ii) A report exists and concludes that the seismic Cateaorv I eouioment can withstand seismic design basis loads without loss of safetv function.

Seismic Category I components in the Table require type tests and/or analyses to demonstrate structural integrity and operability. Structural integrity of the passive seismic Category I mechanical equipment is demonstrated by analysis in accordance with American Society of Mechanical Engineers(ASME)Code Section III (Reference 8).

Safety-related (Class 1E) electrical equipment in the Table is seismically qualified by type testing combined with analysis in accordance with Institute of Electrical and Electronics Engineers (IEEE) Standard 344-1987(Reference 9). The specific qualification method (i.e.,

type testing, analysis, or combination) used for each component in the Table is identified in Attachment A. Additional information about the methods used to qualify API000 safety-related equipment is provided in the Updated Final Safety Analysis Report(UFSAR) Appendix 3D (Reference 10). The EG Reports (Reference 11) identified in Attachment A contain applicable test reports and associated documentation and conclude that the seismic Category I equipment can withstand seismic design basis loads without loss of safety function.

U.S. Nuclear Regulatory Commission ND-21-1095 Enclosure Page 4 of 10 ill) A report exists and concludes that the equipment includina anchorage is seismicallv bounded by the tested or analyzed conditions.

To the extent that the installation prior to fuel load is possible, an inspection (References 1 & 2) is conducted to confirm the satisfactory installation of the seismically qualified components in the Table. The inspection yerifies the equipment make/model/serial number, as-designed equipment mounting orientation, anchorage and clearances, and electrical and other interfaces.

For components not installed prior to fuel load, the inspection is accomplished by yerifying a quality assurance data package (Reference 6 (i.e. fuel assemblies, rod cluster control assemblies, gray rod cluster assemblies, and incore instrument QuickLoc assemblies)) exists that concludes that the equipment was constructed as per design.

The inspection conducted for each component in the table will consider the critical seismic attributes identified in the associated EQ Report for that component. The inspection will confirm that the equipment, including anchorage, is seismically bounded by the tested or analyzed conditions.

Attachment A identifies the EQRR (Reference 7) completed to yerify that the seismic Category I equipment listed in the Table, including anchorage, are seismically bounded by the tested or analyzed conditions, IEEE Standard 344-1987(Reference 9) and NRG Regulatory Guide (RG) 1.100 (Reference 12).

i) A report exists and concludes that the Class 1E equipment identified in Table 2.1.3-1 as being qualified for a harsh enyironment can withstand the enyironmental conditions that would exist before, durino. and following a desian basis accident without loss of safety function for the time required to perform the safety function.

The harsh enyironment Class IE components in the Table are qualified by type testing and/or analyses. Class 1E electrical component type testing is performed in accordance with IEEE Standard 323-1974(Reference 13) and RG 1.89 (Reference 3)to meet the requirements of 10 CFR 50.49. Type testing of safety-related equipment meets the requirements of 10 CFR Part 50, Appendix A, General Design Criterion 4. Attachment A identifies the EQ program and specific qualification method for each safety-related mechanical or Class 1E electrical component located in a harsh enyironment. Additional information about the methods used to qualify API000 safety-related equipment is proyided in the UFSAR Appendix 3D (Reference 10). EQ Reports (Reference 11) identified in Attachment A contain applicable test reports and associated documentation and conclude that the equipment can withstand the enyironmental conditions that would exist before, during, and following a design basis accident without loss of safety function for the time required to perform the safety function.

ii) A report exists and concludes that the as-built Class 1E equipment and the associated wiring, cables, and terminations identified in Table 2.1.3-1 as being qualified for a harsh enyironment are bounded by type tests, analyses, or a combination of tyoe tests and analyses.

An inspection is conducted to confirm the satisfactory installation of the harsh qualified as-built components in the Table. The inspection yerifies the equipment location, make/model/serial number, as-designed equipment mounting, wiring, cables, and terminations and confirms that the enyironmental conditions for the zone in which the component is mounted are bounded by the tested and/or analyzed conditions.

U.S. Nuclear Regulatory Commission ND-21-1095 Enclosure Page 5 of 10 The EQRR (Reference 7) identified in Attachment A document this inspection and conclude that the harsh environment Class 1E equipment and the associated wiring, cables, and terminations are bounded by the qualified configuration and IEEE Standard 323-1974(Reference 13).

Together, these reports (References 7 and 11) provide evidence that the ITAAC Acceptance Criteria requirements are met:

  • The seismic Category I equipment identified in Table 2.1.3-1 (except fuel assemblies, rod cluster control assemblies, gray rod cluster assemblies, and incore instrument QuickLoc assemblies) is located on the Nuclear Island;
  • A report exists and concludes that the seismic Category I equipment can withstand seismic design basis loads without loss of safety function; A report exists and concludes that the equipment including anchorage is seismically bounded by the tested or analyzed conditions;
  • A report exists and concludes that the Class 1E equipment identified in Table 2.1.3-1 as being qualified for a harsh environment can withstand the environmental conditions that would exist before, during, and following a design basis accident without loss of safety function for the time required to perform the safety function; and
  • A report exists and concludes that the as-built Class 1E equipment and the associated wiring, cables, and terminations identified in Table 2.1.3-1 as being qualified for a harsh environment are bounded by type tests, analyses, or a combination of type tests and analyses.
