GALL AMP: XI.S6, Structures Monitoring Program DATE: __________________________

Program Auditable GALL Criteria Documentation of Audit Finding Element Program A. Implementation of structures monitoring under 10 CFR 50.65 Consistent with GALL AMP: Yes No Description (the Maintenance Rule) is addressed in Nuclear Regulatory Document(s) used to confirm Criteria:

Commission (NRC) Regulatory Guide (RG) 1.160, Rev. 2, and NUMARC 93-01, Rev. 2. These two documents provide guidance for development of licensee-specific programs to monitor the condition of structures and structural components Comment:

within the scope of the Maintenance Rule, such that there is no loss of structure or structural component intended function.

Because structures monitoring programs are licensee-specific, the Evaluation and Technical Basis for this aging management program (AMP) is based on the implementation guidance provided in Regulatory Guide 1.160, Rev. 2, and NUMARC 93-01, Rev. 2. Existing licensee-specific programs developed for the implementation of structures monitoring under 10 CFR 50.65 are acceptable for license renewal provided these programs satisfy the 10 attributes described below.

If protective coatings are relied upon to manage the effects of aging for any structures included in the scope of this AMP, the structures monitoring program is to address protective coating monitoring and maintenance.

1. Scope of A. The applicant specifies the structure/aging effect Consistent with GALL AMP: Yes No Program combinations that are managed by its structures monitoring Document(s) used to confirm Criteria:

program.

2. Preventive A. No preventive actions are specified. Consistent with GALL AMP: Yes No Actions Document(s) used to confirm Criteria:

Comment:

3. Parameters A. For each structure/aging effect combination, the specific Consistent with GALL AMP: Yes No Monitored/ parameters monitored or inspected are selected to ensure that Document(s) used to confirm Criteria:

Inspected aging degradation leading to loss of intended functions will be detected and the extent of degradation can be determined.

Parameters monitored or inspected are to be commensurate with industry codes, standards and guidelines, and are to also Comment:

consider industry and plant-specific operating experience.

Although not required, ACI 349.3R-96 and ANSI/ASCE 11-90 provide an acceptable basis for selection of parameters to be monitored or inspected for concrete and steel structural elements and for steel liners, joints, coatings, and waterproofing membranes (if applicable). If necessary for managing settlement and erosion of porous concrete subfoundations, the continued functionality of a site de-watering system is to be monitored.

The plant-specific structures monitoring program is to contain sufficient detail on parameters monitored or inspected to conclude that this program attribute is satisfied.

4. Detection of A. For each structure/aging effect combination, the inspection Consistent with GALL AMP: Yes No Aging Effects methods, inspection schedule, and inspector qualifications are Document(s) used to confirm Criteria:

selected to ensure that aging degradation will be detected and quantified before there is loss of intended functions. Inspection methods, inspection schedule, and inspector qualifications are to be commensurate with industry codes, standards and Comment:

guidelines, and are to also consider industry and plant-specific operating experience. Although not required, ACI 349.3R-96 and ANSI/ASCE 11-90 provide an acceptable basis for XI.S6 Structures Monitoring Program 2

Program Auditable GALL Criteria Documentation of Audit Finding Element addressing detection of aging effects. The plant-specific structures monitoring program is to contain sufficient detail on detection to conclude that this program attribute is satisfied.

5. Monitoring A. Regulatory Position 1.5, "Monitoring of Structures," in RG Consistent with GALL AMP: Yes No and Trending 1.160, Rev. 2, provides an acceptable basis for meeting the Document(s) used to confirm Criteria:

attribute. A structure is monitored in accordance with 10 CFR 50.65 (a)(2) provided there is no significant degradation of the structure. A structure is monitored in accordance with 10 CFR 50.65 (a)(1) if the extent of degradation is such that the Comment:

structure may not meet its design basis or, if allowed to continue uncorrected until the next normally scheduled assessment, may not meet its design basis.

6. Acceptance A. For each structure/aging effect combination, the acceptance Consistent with GALL AMP: Yes No Criteria criteria are selected to ensure that the need for corrective Document(s) used to confirm Criteria:

actions will be identified before loss of intended functions.

Acceptance criteria are to be commensurate with industry codes, standards and guidelines, and are to also consider industry and plant-specific operating experience. Although not Comment:

required, ACI 349.3R-96 provides an acceptable basis for developing acceptance criteria for concrete structural elements, steel liners, joints, coatings, and waterproofing membranes. The plant-specific structures monitoring program is to contain sufficient detail on acceptance criteria to conclude that this program attribute is satisfied.

7. Corrective A. As discussed in the appendix to this report, the staff finds the Consistent with GALL AMP: Yes No Actions requirements of 10 CFR Part 50, Appendix B, acceptable to Document(s) used to confirm Criteria:

address the corrective actions.

8. A. As discussed in the appendix to this report, the staff finds the Consistent with GALL AMP: Yes No Confirmation requirements of 10 CFR Part 50, Appendix B, acceptable to Document(s) used to confirm Criteria:

Process address the confirmation process.

Comment:

9. A. As discussed in the appendix to this report, the staff finds the Consistent with GALL AMP: Yes No Administrative requirements of 10 CFR Part 50, Appendix B, acceptable to Document(s) used to confirm Criteria:

Controls address the administrative controls.

Comment:

10. Operating A. Although in many plants structures monitoring programs have Consistent with GALL AMP: Yes No Experience only recently been implemented, plant maintenance has been Document(s) used to confirm Criteria:

ongoing since initial plant operation. A plant-specific program that includes the attributes described above will be an effective AMP for license renewal.
