,
The inspector reviewed the above listed specifications, procedures, and drawings for the subject grout / concrete operations and protective
,
coating activities to determine if the most recent revisions were employed and in agreement with the SAR.
Procedures were also
examir.ed to determine if they adequately described critical points and cethods of placement / application as well as inspection and test hold points which properly refect design intent.
Within this area, no violations or deviations were identified.
'
b.
Field Inspection
,
The inspector observed selected grout / concrete forms to be tight, clean, and secured and that rebar and embeds were properly installed and clean.
Placement activities pertaining to delivery time, free fall, flow distance, layer thickness, and consolidation of concrete conformed to specifications.
Concrete activities were continuously monitored by QC personnel.
In process sampling of concrete for strength testing, temperature, slump, unit weight, air content frequency requirements, and acceptance criteria were acceptable.
The inspector observed the concrete foreman and craftsmen at work,
,
discussed concreting activities with them, and concluded they were proficient in their trade and performing quality workmanship.
Examination of batch plant operations and material storage facilities revealed that these activities were also being conducted in a quality manner.
Field observations and discussions with randomly selected WPS
'
painting craft and QC personnel were conducted by the insoector to verify proper program implementation for the following phases of
'
protective coatings werk; storage, mixing, surface preparation, environmental condition consideration, coating application, and testing.
The inspector concluded that the WPS personnel possessed

the required knowledge, skills, and training to perform the above tasks per procedure and were doing so.
The inspector examined the application certifications for four WPS craft personnel and found them qualified to perform the coating activities (Coating System FN-6) they were observed working on.
Within this area, no violations or deviations were identified.
c.
Quality Control The inspector reviewed the following inspection records generated for the above observed protective coating applications and concrete placements to determine their adequacy, whether deficiencies submitted by QC inspection personnel received proper corrective action where applicable, and if work and work controls were adequate:
Reinforcing Steel Installation Checklist
'
Embed Inspection Checklist Concrete and Grout Pour Cards Daily Concrete Material Tests - Gradations and Moisture Content of Sand and Aggregate Batch Plant Inspection Checklist
-
Batch Plant Daily Production Report Concrete Batch Tickets
Concrete Placement Pour Log - In process Testing Daily Inspection Report - Fresh Concrete Testing
-
Daily Inspection Report - Fresh Concrete Placement Concrete Postplanned Inspection Report - Curing WPS Contracting Coating Inspection Reports WPS QC Inspector Certification, Qualification, and Training Records The inspector reviewed applicable QA/QC procedures (paragraph 5.a) to
,
determine if the frequency, timing, and acceptance criteria for the subject inspections were adequate.
The number of QC inspectors provided for the coverage of concreting and protective coating
,
activities was satisfactory.
Discussions were conducted with batch plant, laboratory testing, placement, fresh concrete testing, and protective coatings inspectors to determine if their knowledge of the activities they observed was adequate and to determine whether they felt their findings and concerns received proper management attention.
The inspector concluded that licensee and contractor management was attentive and responsive to QC inspector identified problems.
The QC inspectors observed were knowledgeable of their inspection functions and acceptance criteria and were proficient in the performance of their assigned tasks.
Within this area, no "folations or deviations were identified.

Nonconforming Items Reports The ins)ector reviewed all deviation reports written by WPS on protect've coatings from 1987 to date and selected construction deviation reports on concreting activities identified during this same interim to verify that the corrective action accomplished the following:
Corrected the items Determined the cause of the deficiency Considered reportability to the NRC Instituted effective action to prevent recurrence The licensee has an adequate program to detect trends in discrepancies Protective coating related deviation reports reviewed included the following:
WC-87-001 through WC-87-006 inclusive.
Concrete related deviation reports reviewed were:
CD-9356, CD-9355, CD-9354, CD-9352, C0-9351, CD-9350, CD-9342, CD-9340, CD-9336, CD-9328, 00-9322, CD-9318, CD-9313, and CD-9308.
Review of concrete related deviation reports identified several which involved unauthorized cutting of rebar.
Discussion with responsible licensee QC, engineering, and technical support personnel indicated that this was an old problem which occurred in the past with one particular contractor. This problem was stopped and satisfactorily corrected.
The deficiencies that have been recently identified are generally due to engineering a) proved core drill operations or are remnants of the above old pro)lem which are coming to the sites attention now because they are filling in temporary blockouts of previous old concrete wall placements.
The last two QC Deviation Trend Reports (87-6, 88-1) identified this adverse trend which is being properly handled.
All blockout pours are receiving extensive i
reviews and inspections by engineering /QC prior to concrete 31acement
'
and are being documented to as-built conditions.
All deviations reports with the recommended disposition of "Repair" or "Use-As-Is" receive Bechtel Engineering evaluation.
Review of several such deviation reports revealed adequate measures and design reviews have been taken.
Within this area, no violations or deviations were identified, e.
Materials and Equipment The inspector examined three paint-storage areas (Warehouse B, C, and the Main Coating Facility) and found properly controlled
,
environmental conditions being adhered to and that all nuclear coatings material stored there was either within allowable shelf life or properly segregated and identified as nonconforming.
The
'
February 1988 monthly warehouse temperature reports were examined for i

the above storage facilities and found satisfactory.
Warehouse and-inspection test equipment (High-low temperature thermometers,-surface temperature thermometers, magnetic dry film thickness gauges, sling psychrometers) being utilized during protective coating activities were observed to have current calibration stickers.
Equipment calibration is controlled by the Georgia Power Construction QC Department.
Coating materials were found to be controlled and traceable from purchase through final use.
Examination of the batch plant indicated that materials were being controlled and accurate batch records were being generated.
Storage of materials (aggregates, cement, and admixtures) were observed to be in accordance with specification requirements..
Batch plant activities were continuously monitored by a QC inspector.
The inspector - examined the in process concrete and grout testing equipment utilized for the subject placements, the concrete batch plant scales, and various laboratory testing equipment for current calibration evidence.
,
Within this area, no violations or deviations were identified.
f.
Audit and Surveillance Reports The inspector reviewed the following contractor and licensee conducted audits /surveilliances which were performed on various phases of protective coating and concreting operations:
WPS-1-87 WPS Annual Audit of Vogtle's Coatings Program WPS-86-008 WPS Annual Audit of Vogtle's Coatings Program CP01-87/60 QA Assessment of WPS CP01/CP14-86/28 QA Assessment of WPS CP14-86/27 QA Audit of Coatings CP14-87/10 Coatings Surveillance CP13-86/43 QA Audit of Concrete and Reinforcing Steel CP13-87/16 Concrete Activities Surveillance CP13-86/27 Concrete Placement Surveillance CP13-86/17 Concrete Placement Surveillance The above audits and surveillances were examined to determine if they were meaningful, effective, reflected quality performance, and whether corrective actions taken as a result of audit / surveillance findings were proper, timely, and complete.
Within this area, no violations or deviations were identifie l
