~
This temporary instruction (TI) provides guidance for conducting assessment inspections of maintenance at selected operating nuclear power stations.
2515/108-02 OBJECTIVES The objective of this TI is to examine the scope and effectiveness of
' corrective actions taken as a result of previous maintenance team inspections conducted under T1 2515/097, Revision 1 and to arrive at an assessment of the status of present maintenance at a site as compared to the status of maintenance at the time of the previous inspection.
I 15/10B-03 BACKGROUND The Comission has approved criteria to be used by the staff in determining when industry progress in the area of maintenance is sufficient to obviate
-the need for rulemaking.
One factor to be considered in this determination is the progress that licensees, previously assessed as needing improvement, have made in improving key areas of maintenance.
This TI was developed to
. reinspect and assess the effectiveness and relative improvement in main-tenance, of selected licensees. Many improvements may be directly related to corrective action of specific findings from the original maintenance inspection.
Improvement may also be attributable to current industry initiatives.
2515/108-04 CONDUCT Reinspections are to be conducted at plants where T1 2515/097, Rev. 1 iden-tified the maintenance process to be in need of significant improvement in the inspection tree (e.g. [1] Overall Plant Performance' Related' to Main-
-tenance, [11] Management Support of Maintenance, or [111] Main.tenance Implementation). The reinspections of selected plants may also include those areas where TI 2515/097 Rev.1 or where other regional effort indicated good 9305270198 901019 PDR I&E MANUAL PDR

maintenance performance (e.g. sections 4.0 Technical Support and 5.0 Work Control of the maintenance tree). It is expected that the regions I, II, and III will conduct two reinspections each and regions IV and V would conduct le re-inspection each.
TI 2515/097, Rev. I and related maintenance inspection guidance shall be used in conjunction with this TI.
The Maintenance Inspection Tree (tree) will continue to be used as guidance during these inspections to collate and present inspection findings and for comparison to the previous inspection results.
The tree is intended to provide a systematic inspection approach and to ensure consistency.
The reinspection should include a review of Tl 2515/097, Rev. I findings that remain as open items (weaknesses, un-resolved items, and violations).
The maintenance reinspection will be announced when.the team leader prepares for the pre-inspection visit (T1 2515/097, Rev. 1 section 04.01) to the site.
The reinspection will generally be of a three week duration. The team effort should generally consist of about I week of preparation, I week of onsite inspection, and I week of documentation. Generally, the inspection team will be composed of 2-4 members, depending on the nurber of areas to be rein-spected at a particular site.
The team composition and/or the extent of effort for individu~al members may be adjusted by the region.
In addition, headouarters may assign an individual to some of the teams.
To provide raximum efficiency, only personnel with prior reintenance team inspection experience should be used, as available resources permit.
Ideally, the team leader should have participated in the original maintenance inspection at the site to be reinspected.
'he inspection requirements for this temporary instruction reference those in i 2515/097, Rev. 1. The amount of inspection effort devoted to the individ-t ual subsections of the tree will be determined by the regional office, taking into account the previous inspection findings, time and staff limitations, and specific site activities since the previous inspection. The reinspection of the selected areas should be performed using TI 2515/097, Rev. I guidance as an aid in determining adequacy and implementation of maintenance activi-ties.
In preparing for the reinspection, the evaluation of elements iden-tified as poor or needing improvement from the previous inspection tree should be carefully reviewed.
04.01 Team _ Leader Preparation.
The previous maintenance team inspection report should be the primary tool for guiding the team's preparation and selecting areas for reinspection. Other requirements are as per TI 2515/097, Rev. 1 section 04.01.
04.02 Inspection preparation.
In preparing for the onsite inspection, the inspection team should review the previous maintenance inspection report to determine which areas should be selected for reinspection.
The licensee's response to the original report should also be reviewed, as well as signif-icant maintenance related events since the previous maintenance inspection.
The inspector should determine the status of corrective actions taken and their effectiveness.
See TI 2515/097 Rev. I section 04.02 for additional guidance.
04.03 Onsite Inspection.
The guidance of this section is the same as that
'n TI 2515/097, Rev. I section 04.03.
Issue Date: 10/19/90 2515/108 i
04.04 Analysis.
Using the reinspection findings, the team should determine whether each of the areas reinspected has been adequately implemented and ssign a rating based on the criteria in the Maintenance Inspection Guidance.
.or those areas reinspected, use TI 2515/097, Rev. I tree and fill in the appropriate portions (e.g. Direct Measures, Management Commitment and In-volvement, etc.) to determine whether or not that area has improved, de-clined, or remained steady since the previous maintenance inspection.
Specific justification, including examples of performance should be docu-mented to substantiate an improving or a declining rating.
Similarly, an overall performance rating (top block) should be determined to be improving, declining, or steady relative to the previous TI 2515/097, Rev. 1 inspection results.
04.05 Exit Meeting.
The requirements of this section remain the same as those in Tl 2515/097, Rev. I section 04.05.
p 04.06 Report Preparation.
The final report should document assumptions used, elements inspected, licensee strengths and weaknesses, and overall i
conclusions consistent with IMC-0610. The report should address the elements I
covered by the reinspection, describe the ratings assigned for subcategories with justification ' and address the overall trend in maintenance at the inspected site.
04.07 Follow Up.
Any new unresolved findings identified during the inspec-tion will be appropriately tracked and resolved by the regional office.
I 515/108-05 IN5pECTION REQUIREMENTS The reinspection shall include examinations of the aspects of maintenance in selected areas from those listed in Section 05.01 through 05.03.
To the extent possible, selective examinations should be based on observation
. of maintenance and equipment work activities in progress, review of licensee implementation of maintenance procedures and centrols, results of review of selected documents (such as work packages, equipment test results, and engineeringevaluations),andinterviewswithpersonnel.
6 The selection of elements for reinspection shall include all elements pre-viously rated as poor at that particular site.
Additional elements may be selected from other areas, including those previously rated as weak or good in order to get a balanced view as to whether the maintenance process is declining or steady.
