NRC INSPECTION MANUAL DI
MANUAL CHAPTER 2920
CONSTRUCTION APPRAISAL TEAM INSPECTION PROGRAM
2920-01 PURPOSE The purpose of this chapter is to describe the methodology for performing the multidisciplined construction appraisal team (CAT) inspections at nuclear power plants under construction.
2920-02 OBJECTIVE The objective of the CAT inspection program is to determine through an integrated multidisciplined approach that (1) the facility is being constructed and the hardware is being installed in accordance with regulatory requirements and appropriate industry practices, and (2) the applicant's management and quality control programs are effective. The team inspections focus primarily on hardware installation and construction quality. Documentation is reviewed to the extent necessary to understand the applicant's programs to provide for final hardware installations of appropriate quality.
Guidance for the development of facility-specific inspection plans is included. The results of the CAT inspec tion and evaluation provide an input for the assessment of the effectiveness of the regional implementation of the NRC construction inspection programs, and an input for the overview of INPO construction facility audits.
2920-03 DEFINITIONS 03.01 Hardware: Foundations, structures, systems, equipment, and components.
03.02 Potential Enforcement Finding: An apparent noncompliance with specific regulatory requirements or deviation from specific commitments made by the applicant that are identified during the CAT inspection. Regional management of the applicable regional office is responsible for deciding the appropriate enforcement action to be taken in accordance with 10 CFR 2, Appendix C.
03.03 Inspector Observations: An item of concern identified during the CAT inspection that, while not related to specific regulatory requirements or applicant commitments, is a departure from appropriate engineering/construction practice and is signifi-cant enough that applicant management should ta ke corrective action.
Issue Date: 03/29/85 2920 03.04 Applicant or Licensee: Utility that holds the construc-tion permit.
2920 Issue Date: 03/29/85 03.05 Integrated Design Inspection (IDI): Multidiscipline inspection performed to assess the quality of design activities on a nuclear power plant project. The inspection provides a comprehen-sive examination of the design development and implementation for a selected plant system. An IDI may precede or follow a CAT inspection for a specific or replicate plant.
2920-04 RESPONSIBILITIES AND AUTHORITIES 04.01 Director, Office of Inspection and Enforcement. Selects facilities to be inspected based on input from the NRC offices and the regions, and issues the results of inspections.
04.02 Director, Division of Inspection Programs, IE. Adminis-ters the CAT program.
04.03 Chief, Reactor Construction Programs Branch, IE.
Implements the CAT program.
04.04 Regional Administrator. Determines the scope and schedule for applicant responses to the inspection report and determines final action on potential enforcement findings.
2920-05 INSPECTION CONCEPT 05.01 The concept of CAT inspections at nuclear facilities under construction is based on concurrent inspections and sub sequent evaluation of the installed hardware quality by a multidisciplinary team. The primary focus of the effort is on actual quality of in situ hardware with review of documentation to the extent necessary to identify the strengths and weaknesses of the applicant's programs. The functional areas that should be considered in the performance of this inspection are listed in 06.05c below.
05.02 The determination of the facility hardware quality and the effectiveness of the applicant's programs to provide for appropriate hardware quality is made generally by the following process:
- a. Define the scope and depth of the CAT inspections for aparticular facility using criteria selected from the guide-lines provided in Appendix 1 of this manual chapter. This definition should be based upon consideration of the facil-ity's past inspection history and salient features. The scope of the inspection is defined during the planning and prepara-tion phase, and appropriate revisions are made as the inspection progresses.
- b. Determine the quality of hardware as compared with thatdictated by appropriate application of design, construction, and maintenance specifications. In addition, the adequacy of the specifications, on the basis of inspector observations, should be jud ged consider ing appropriate engineering/construction practices which may or may not be incorporated into the governing specifications such as regulatory guides, NRC staff positions, consensus standards
Issue Date: 03/29/85 2920 (e.g., ANSI, IEEE, ASME, ACI, and AISC), and NRC interpretations.
- c. The applicant's programs to provide for hardware qualityshould be compared with the criteria for effective programs to the extent necessary to understand the strengths and weaknesses of the applicant's programs. The criteria to be utilized are regulatory requirements, applicant commitments, and/or appropriate practices as discu ssed in 05.02b above.
If the applicant is not committed to the appropriate engineering/construction practices and the applicant's program(s) is (are) inferior to the appropriate practice(s),
this is identified as an observation of applicant program weakness.
- d. Verify that the construction programs including qualityprograms are implemented. This verification is performed during the site inspection by observations of installed hardware, work in progress, discussions with site personnel during the conduct of the inspection, and quality program reviews.
- e. Evaluate management involvement by discussipersonnel and limited reviews of documentation, augmented byons with management information obtained as a result of the efforts described in 05.02d above.
- f. Evaluate any program weaknesses identified by a preceding IDIwhich could be expected to affect installed and inspected hardware so as to be apparent in an inspection of hardware quality. Identify for any following IDI design-related construction problems which should be considered for followup during IDI.
2920-06 PROGRAM GUIDANCE 06.01 Program Timetable and Scope. IE management will determine the frequency of the implementation of the CAT inspections and evaluations. The scope of the program at a particular facility is to accomplish a multidisciplined inspection of the overall quality of the facility's hardware and within a given discipline to focus primarily on potential areas of concern. The factors to be considered in the inspection plan devel opment and implementation are delineated in enclosed Appendix 1 of this m anual ch apter. The planning, inspection, and reporting for each facility should be completed within an approximate 3-month period. This schedule provides about 2 weeks for team planning, two 2-week onsite inspection periods separated by a 1-or 2-week preliminary evaluation and plan reassessment period, and a 1-month period for documentation of inspection results.
06.02 Team Member Assignments. Inspector assignments to the CAT shall be based on the expertise needed to implement the scope of the inspection planned for a particular facility. Consideration will be given to assignments of IDI team members to the CAT, particularly
2920 Issue Date: 03/29/85 those who have or are expected to participate in an IDI on the same or a replicate plant.
06.03 Regional Participation
- a. The applicable regional office will be given an opportunity to assign regional inspectors to the construction appraisal team. Regional personnel that are assigned to CAT will report to the Team Leader for direction during the conduct of the inspection. Input for the CAT inspection report from assigned regional personnel shall be provided directly to the Team Leader.
- b. The evening before the exit briefing the team will meet toreview their findings. The regional office is encouraged to be represented at this meeting.
- c. The regional office is encouraged to be represented at theentrance and exit briefings with the applicant.
06.04 Information Acquisition. Before initiating the team planning phase for a facility inspection, the Team Leader, or his representative, will contact and/or meet with regional representatives and applicant representatives, as necessary, to identify and obtain information related to the factors identified in 06.05b below. The CAT inspectors should review the report from any preceding IDI, discuss relevant findings with the IDI Team Leader and members, and obtain specific information on any problems requiring further investigation during the CAT inspection.
In addition, the team should obtain information about the applicant's document control and filing system; design, construction, and maintenance criteria; and governing construction drawing and specification definition summaries for the various disciplines. This information must be available to the team for the efficient development of a meaningful facility-specific inspection plan. During this time, NRC inspection specialists and contractor personnel should participate in the preparation of the inspection plan.
06.05 Inspection Planning and Preparation
- a. A key element for a successful team inspection is detailed planning and preparation. The objectives of planning and preparation are
- 1. To identify those elements that are applicable to thespecific facility inspection.
- 2. To formulate a detailed inspection plan appropriate forthe particular facility. The inspection plan should be a guide for performing inspections and should be revised based on the results of ongoing inspection activities.
- 3. To make specific functional assignments to each teammember.
Issue Date: 03/29/85 2920
- 4. To define inspection schedules.
- 5. To familiarize the team members with the facilityorganization, procedures, specifications, and drawings that define construction and program requirements.
- 6. To indoctrinate team members to the team concept. Beforethe start of the onsite inspection the Team Leader should conduct an indoctrination session for the team members on the concept of team inspections and disc uss the broad schedule, inspection ground rules, and areas of assignment. As the team refines the elements of the inspection by defining priorities, inspector capabilities, and site status, detailed inspection assignments are made and parallel activities are identified. The inspection plan scope should be based on two 2-week periods on-site with a 1-or 2-week period separating the two for reassessing and revising the plan.
- b. The team member(s) assigned a functional area should developan inspection plan for that area using Appendix 1 of this chapter as guidance. Appendix 1 may be supplemented as required by using applicable inspection procedures contained in the IE Manual. The team members will use the following materials in planning the details of and preparing for the onsite inspection:
- 1. Safety Analysis Report and facility design/constructionspecifications and drawings that define requirements and commitments.
- 2. Inspection history - inspection reports and docket filesprovide an overview of regional activity and applicant performance and aid in developing priorities.
- 3. Licensee reports - repo rts submitted by the applicant(such as 10 CFR 21 and 50.55(e) reports) provide indications of the effectiveness of the applicant's program.
- 4. Applicant manuals - arrangements should be made to obtainthe project manual, quality assurance manual, topical reports, and admin istrative control manuals, as required.
These documents provide the basis of management controls at the site and define responsibilities, authorities, interfaces, and procedural aspects of project control.
- 5. Contractual arrangements - the degree to which theapplicant acts as his own A/E, use of separate A/E and multiple consultants, and constructor use of multiple contractors are primary inputs into the sample definition required to provide for evaluation of interface effectiveness and an adequate cross-section of the work of various contractors.
2920 Issue Date: 03/29/85
- 6. Construction status - stage of completion will dictate the scope and types of inspections and evaluations appropriate for a particular discipline.
- 7. Organization charts - provide the inspectors with anoverview of the management interfaces, communic ation channels, and the identification of management personnel.
Each inspector must develop an understanding of the organization and identify those managers and supervisors to be contacted.
- 8. NRC staff positions/interpretations/regulatory guides(RGs) - current NRC (NRR or IE) staff positions/interpretations/RGs define the most recent NRC planning and the determination of acceptability of thepositions and should be considered in the detailed applicant's program.
- 9. Consensus standards - ANSI/ASME/IEEE/ACI/AISC standardsshall be used as applicable.
- 10. Regional management and inspector impressions ofconstruction adequacy in the various disciplines.
- 11. IDI reports that are specific to, or a replicate of, theplant where the CAT inspection will be conducted. In particular, the system(s) inspected by any preceding IDI should be considered in the CAT hardware sample selected for each functional area. The intent is for the CAT and any related IDI to provide for an in-depth vertical sample examination of a particular system from design through construction. Duplication of effort should be avoided.
- c. The planning and preparation stage should result in an initialinspection plan which will ensure that the objectives of this chapter are met. It is the responsibility of the Team Leader to integrate each team member's proposed plan/schedule/
activities into an overall plan and to coordinate the inspection activities.
The inspection plan should be formulated to address the following functional areas as a minimum:
- 1. Civil/structural construction, including design changecontrol
- 2. Mechanical construction, including design change control
- 3. Electrical: power, instrumentation, and controls,including design change controls
- 4. Welding and nondestructive examination (NDE), includingdesign change controls
Issue Date: 03/29/85 2920
- 5. Traceability and maintenance and storage (both in-place and preinstallation) 1
- 6. QA/QC inspector effectiveness and corrective action systems1
- 7. System turnover from construction to operation (only at sites that have established the turnover mechanism) 1
- d. The depth of NDE performed by or under the direction of the CAT will be dictated by the particular circumstances at a facility. In special situations and as dictated by relative importance to completion of the overall inspection scope, limited destructive or semidestructive examinations may be conducted under the direction of the CAT, as approved by the Chief, Reactor Construction Programs Branch. Such needs must be presented to the applicant as soon as they are identified to provide for their timely completion. Also, such examinations may require additional contractor assistance, which requires as much advance notice as possible.
- e. The initial inspection plan may be revised as the inspectionprogresses to focus on more meaningful areas. The Team Leader is responsible for arranging/directing changes to the initial inspection plan.
2920-07 INSPECTION CONDUCT AND DOCUMENTATION 07.01 General. All team members should be dedicated for the duration of the ins pection. Each day, the Team Leader should conduct a coordination meeting of all team members to discuss the day's activities and findings. As a result of such meetings, team members may be given additional assignments or their effort may be redirected.
At the beginning of the inspection the applicant should be asked to appoint representatives as points of contact for each of the functional areas, as appropriate. It is the responsibility of the inspector assigned to each of the functional areas to apprise the applicant's representatives of the progress of the inspection on a daily basis through informal 2 contact. This will expedite the exit meeting conducted by the Team Leader at the end of each onsite period.
07.02 Entrance and Exit Interviews
1 These areas overlap with areas 1, 2, 3, and 4. The inspectors assigned areas 5, 6, and 7 and the inspectors assigned areas 1, 2, 3, and 4 will decide "who inspects what" during the preparation phase.
2 Only requests for information may be given the applicant's representative in writing without the approval of the Team Leader. All other information given the applicant in writing must be approved by the Team Leader. It is important to ensure that information requests do not include any information about inspection results or findings.
2920 Issue Date: 03/29/85
- a. An entrance interview between senior applicant management and all CAT members shall be held bef ore starting the onsite inspection. The regional office is encouraged to be represented at this meeting. IP 30703, "Management Meeting
- Entrance and Exit Interviews," should be used as guidance when conducting the entrance interview.
- b. An exit interview shall be held between senior applicantmanagement and the CAT Team Leader at the conclusion of each of the 2-week inspection periods. Individual CAT membe rs will participate at the discretion of the Team Leader. IE management also may attend the exit interviews. The regional office is encouraged to be represented at these meetings. The designated Team Leader for any IDI scheduled to follow the CAT inspection should be invited to attend the final exit interview. For a plant where an IDI is not scheduled to follow a CAT and CAT findings indicate that a limited IDI for the on-site design function may be warranted, the IDI Team Leader also should be invited to attend the final exit. IP 30703 should be used as guidance when conducting the exit interviews.
The exit interview will be used to summarize the findings and to convey the significance thereof to senior applicant management. The results of the inspection shall be openly and be freely discussed, but the results or findings shall not given the applicant in writing. This will ensure that preliminary information is not provided "via draft reports" before the final report is issued. 2 07.03 Inspection Documentation The team will prepare an insp ection report for issuance by the Director, IE, or his representative, that documents inspection activities and findings identified during the inspection. The inspection report and related transmittal correspondence should be transmitted within about 1 month after completion of the onsite inspections.
The CAT inspection concept employed in this procedure includes an evaluation of overall hardware and construction quality and a determination of applicant program effectiveness. Therefore, in addition to using specific requirements and commitments as a basis of evaluation, the inspector may be using other criteria for which explicit regulatory requirements may not exist, such as regulatory guides, staff positions and interpretations. Consequently, in addition to inspection findings, which are potential enforcement findings, the report may contain other observations which of and by themselves, add up to perceived strengths or weaknesses. If it is found that the hardware quality or the applicant's program does not meet these criteria, the finding is considered as an observation of weakness or inadequacy. The hardware quality or the applicant's program could exceed requirements, commitments, and these other criteria, so that this program element is superior. In this situation, it would be considered as an observation of strength.
Issue Date: 03/29/85 2920
- a. Inspection Report. The cover page to the report will conform to IE MC 0610. The body of the report will identify the scope and results of the inspection. In addition, to identifying potential enforcement findings, each major inspection topic area discussed will include the other observations of perceived strengths and wea knesses discussed above. The topic areas addressed should include as a minimum the functional areas listed in 06.05c above.
appropriate The potential enfor cement findings together with the otherobservations, provide the basis for evaluation of facility hardware quality and the effectiveness of the applicant's system of controls. The report should identify as clearly as possible the perceived reasons that caused the weakness or strength to exist and should not just repeat the weakness or strength.
- b. Transmittal Letter.3 The transmittal letter will generally conform to the example contained in Appendix 2 of this manual chapter.
- c. Appendix A - Executive Summary.3 The Executive Summary should summarize the significant overall conclusions and the scope and results of the CAT inspections and evaluations.
- d. Appendix B - Potential Enforcement Findings.3 This appendix summarizes any apparent noncompliances with specific regulatory requirements or deviation from specific commitments made by the applicant that are identi fied dur ing the CAT inspections. Explicit references to the detailed section of the inspection report are made for complete descriptions of the bases for the potential findings. These are referred to the appropriate regional office for review and necessary action.
- e. Appendix C - Inspector Observations.3 This appendix summarizes items of concern identified during the CAT inspections. These items, while not rela ted to specific regulatory requirements or applicant commitments, are departures from appropriate engineering/construction practices and are significant enough that applicant management should take corrective action. Explicit references are made to the detailed section of the inspection report for complete descriptions of the bases for these items. This appendix may not be required for all CAT inspection reports.
- f. Distribution. The CAT report will be sent to the appropriate Regional Administrator at the same time it is sent to the applicant. After proprietary clear ance the report will be distributed using the region's standard distribution for the inspected facility. In addition, the report will be sent to all utility executives using distribution list 1S, and to

GUIDANCE FOR INSPECTION PLAN DEVELOPMENT
A. PURPOSE To provide guidance in developing an inspection plan for conducting a CAT inspection.
B. SCOPE This planning guidance is intended for all areas covered by the CAT inspection:
- 1. Civil/structural construction, including design changecontrol
- 2. Mechanical construction, including design change control
- 3. Electrical: power, control and instrumentationconstruction, including design change control
- 4. Welding and NDE, including design change control
- 5. Material traceability, maintenance, and storage (bothin-place and preinstallation) 1
- 6. QA/QC inspector effectiveness and co rrective action systems1
- 7. System turnover from construction to operation (only atsites that have established the turnover mechanism) 1
This inspection will focus on components, sys tems, and hardware important to safety to determine conformance to engineering design, regulatory requirements, and applicant commitments. The CAT inspectors will concentrate on "hands on" inspections of selected components, systems, and hardware to evaluate quality and conformance to specifications. To the extent necessary to evalua te deficiencies observed in the hardware, the applicant's construction, inspection and QA procedures, and documentation controlling on-going and completed work will be reviewed.
1 These areas overlap with areas 1, 2, 3, and 4. The inspectors assigned areas 5, 6, and 7 and the inspectors assigned areas 1, 2, 3, and 4 will decide "who inspects what" during the preparation phase.
Issue Date: 03/29/85 A-1 2920 Appendix 1 C. PLAN PREPARATION
- 1. Background Review In preparing the plan for these inspections the following information should be reviewed:
- a. Recent inspection reports (last 6 months)
- b. 10 CFR 50.55(e) reports
- c. Allegations/investigations
- d. FSAR requirements and commitments
- e. National standards (ASME, AWS, ANSI, IEEE, etc.)committed to by the licensee
- f. Construction, inspection, and QA procedures
- g. Drawings
- h. The IDI report for the same plant or one of similardesign.
Each inspector should review these documents or portions of documents applicable to his assigned technical area.
Items a through c should be reviewed for the purpose of guiding or focusing the inspections. The inspectors should not spend excessive amounts of time in areas that the region has recently identified as a problem area in the inspection reports. Inspection efforts in these areas should be limited to seeing if the problems continue in present work and that corrective action is being taken on previously identified defective work.
Areas identified in 10 CFR 50.55(e) repo rts should betreated in the same manner.
Allegations should not be pursued. These are the responsibility of the Regional Office and/or Office of Investigations.
Items d through g should be reviewed principally to identify licensee commitments and physical characteristics to be used during the hands on inspections (dimensions, tolerances, accept/reject criteria materials heat treatment, etc.)
- 2. Sample Selection The following guidance on selecting samples for inspection is prioritized in descending order of importance:
- a. The sample size selected in each area inspectedshould be representative of the ins talled and inspected hardware.
2920 Appendix 1 A-2 Issue Date: 03/29/85
- b. The samples selected should be representative of the different contractors and vendors, shop, field, and site work.
- c. Sample should be selected from different buildingson the site and if it is a multiunit site, from those units still under construction.
- d. A sample should be selected, in all disciplines, ofhardware associated with the system(s) inspected by any preceding IDI.
D. IMPLEMENTATION
- 1. Inspect samples of completed installat ion, after licenseeQC inspections, to determine work conformance to design requirements.drawings, specifications, site procedures, and FSAR
- 2. Observe ongoing work and interview crafts and QCpersonnel as to work skills, knowledge of procedures and requirements, and compliance with design and procedural requirements.
- 3. Review procedures and QA/QC documentation to the extentnecessary to evaluate causes of deficiencies observed in hardware or documentation.
