_ REGIONAL CONSTRUCTION INSPECTION PROGRAM ASSESSMENT - CLINTON POVER STATION (R-III)
I.
OBJECTIVE The objective of this assessment is to evaluate Region III's implementation of the Light Water Reactor Inspection Program-Construction Phase (construc-tion inspection program) and to make an overall assessment of the adequacy of Region III's oversight of construction activities at the Clinton Power Station site.
{
The Construction Appraisal Team (CAT) of the Division of Inspection Programs conductea an anr.ouated conttruction inspection at the Illinois
' Power Company's C1tnton Power Station during the period of May 20-31 and June 10-21, 1985. While the predominant effort of the inspection team was devoted to hardware inspection, the team also evaluated the control of design changes and corrective actions.
II. Assessment Activities A review was made of Region III inspection reports of the Clinton Power Station (CPS), SALP reports, and construction deficiency reports to identify those deficiencies that were previously identified by Region III inspectors or the licensee. The review included inspection reports of 1979 to 1985, applicable open items and violations and SALP reports for
{
the periods ending September 30, 1982 and February 29, 1984.
To determine the inspection effort at CPS, the inspection reports for 1979 through April 1985 and the 766 Computer System inspection data were analyzed.
It was determined that Region III performed a total of 10370 manheurs of direct inspection effort at the CPS site with apprcximately 330 manhours recorded for January through April,1985.
The site total and 1985 inspection hours were compared to other sites in a similar stage of construction and the manhours were found to be compar-able, thus indicating a satisfactory level of inspection effort at the site. Attachment I graphically depicts the comparison of inspection hours.
The analysis of the inspection reports and 766 Computer System data indicated that the construction inspection program was approximately 85 to 90 percent complete at the start of the CAT inspection.
)
The Executive Summary and Potential Enforcement Actions of the CPS CAT inspection report (50-461/85-30) are provided as Appendix A and Appendix B, respectively.

III. Assessment Findings A.
Electrical and Instrumentation, Construction
'i 1.
CAT Findings The CAT inspectors found electrical separation criteria had not been met in a number of raceway installations, and cur-rent walkdown activities were not adequate to ensure compliance with commitments.
Analysis to justify lessor spatial separation also was found being used which is inconsistent with current FSAR commitments.
Separation deficiencies also were found with vendor wiring in main control room panels.
The use of flexible conduit as a fire barrier in these panels requires additional review by NRR.
The CAT inspectors identified unperformed inspections and unqualified wire with safety-related work performed by the licensee's plant staff under the fiaintenance Work Request Program.
Several QC acceptea medium-voltage terminations were identified which were not insulated although insulation is required by the design, installation and inspection docu-ments.
2.
Assessment Raceway separation is discussed in two inspection reports reviewed. One resulted in an open item for conduit-to-con-l duit separation and the other resulted in a violation for cable tray-to-cable tray separation (report 50-461/81-27).
The lack of inspection by the licensee for separation was not discussed in the reports.
However, due to continuing problems in the electrical area and many cable iray and hanger deficiencies and violations documented in report 50-461/82-02 the first electrical stop work order was issued by the Itcensee. This was followed by a stop work order for conduit as well.
Except for the separation violations no other significant deficiencies were identi-fled by the CAT with raceway or raceway supports.
The region identified separation problems with PGCC cables, documented in reports 50-461/81-05 and 81-09, and issued violations.
These resulted in FSAR changes and NRR revitw and approval of flexible conduit as a fire and separation barrier for particular circuits in the PGCC, lhe CAT found that this specific approval was extended by the PGCC vendor and the AE into main control boards which are outside the approved PGCC scope.
The resident inspector documents in his inspection reports an ongoing process of alerting the licensee to problems encountered at other sites which may have applicacility to 2

.M 7-CPS. One such item, which was confirmed to be a problem by the if censee and for which corrective actions were taken, was the use of unqualified wire.
Since the only unquali-fled wire found by the CAT was installed under the Main-tenance Work Request Program it appears that, the region's 3
inspection program at this stage should place more emphasis en work performed by Illinois Power Company's plant staff.
Cable installation and termination inspections are docu-rented in several regional inspe: tion reports. However, only one inspection of terminations is documented af ter completion of the deficient terminations noted by the CAT and that inspection included only one of the type found deficient by the CAT.
Although the inspection procedure requires the inspector to select at least two cables of the type found deficient, the region has not yet completed the procedure's inspection requirements.
The status of the electrical inspection procedure s is comensurate with site construction and are virtually all completed. The most major effort remaining is completion of IP 510648, Electrical (Cables and Terminations II) - Work Observation. However, only about half of the instrumenta-tion inspection procedures have been completed.
This is apparently because regional instrumentation inspections had been deferred for follow up and resolution of an electrical instrumentation stop work order.
A recent region inspec-tion report did identify problems with instrumentation lines and instruments and a number of apparently isolated problems also were identified by the CAT.
3.
Recommendations The construction inspection program procedures for electrical and instrumentation construction are adequate.
Additional regional emphasis is required for inspection of raceway sepa-ration and inspection of electrical construction perfomed by piant staff. This can be accomplished during the region's com-pletion of IP 51064B and the remainder of the instrumentation procedures.
It is recomended that since a significant portion of the instrumentation modules need to be completed that the current inspection procedures, issued March 1984, be used.
8.
Mechanical Construction 1.
CAT Findinos The CAT inspectors identified a lack of control regarding the removal of temporary supports, and the piecemeal formulation of the program for identification and evalua-tion of potential interferences and interactions, i
i 3
i
^.:' '
n.
Tlf,i. 1 w'p' The CAT inspectors identiffef an interface deficiency with the extension piece manufactured and provided by Basic Engineering and the snubber unit jrovided by Pacific Scientific Company.
Two ASME Class 1 snubber supports w?re found to have been modelled and analyzed in a manner contrary to FSAR commit-ments.
The CAT inspectors identified a lack of attention to detail by QC personnel during their inspections of Class D pipe supports / restraints.
2.
Assessment Previous Region III inspectito reports had not addressed the lack of control regarding the removal of temporary supports nor a review of the pro;; ram.
However, Region III was aware of this issue prior to the CAT inspection.
The two incorrectly modelled and analyzed ASME Class I snubber supports normally would not have been identified through implementation of the construction inspection procedures.
The region's inspection sample of pipe supports / restraints did not appear to include the licensee's Class D inspection program and, therefore, the lack of attention to detail by l
QC personnel would not have been identified.
The numerous instances of wooden scaffold in contact with or supported by permanent pipe st:pports/ restraints compo-nents were similarly identified in Region III inspection report 50-461/81-25 for electrica~l cable pan rails and hangers.
The Region III follow up inspection report 50-461/84-29, item 50-461/81-25-04, indicated that the licensee has stopped using cable pan rails and hangers for supporting scaffolds and this item was closed. However, the concern with scaffolding in contact with mechanical piping and supports was not addressed in either of the refer-enced inspection reports.
sal.P report 50-461/84-03 noted a rating of Category 2 for the three mechanical areas.
This rating is consistent with the CAT's conclusions.
3.
Re: emendations The construction inspection program is determined to be ade-quate, but DI/RCPB will evaluate of the need for a specific inspection requirement or guidance relative to licensees' programs for the removal of temporary supports.
Region III will need to follow the licensee's corrective actions for the removal of teeporary supports and incorrectly modelled supports and other CAT findings.

Weldino - NDE Y
1.
CAT Findings The CAT inspectors found that vendor procured tanks and heat exchangers were accepted and installed with deficient welds.
In addition, some of the reviewed vendor radiographs for the containment ifner and dry well wall area did not have the required weld an') film quality.
2.
Assessment Past CAT inspections have also identified welding deficiencies in vendor provided equipment.
This problem has been brought to the attention o' the Vendor Program Branch and they are modify-ing their inspection approach in an attempt to reduce the number of these types of deficiencies that are being found in the field.
l 3.
Recommendation The construction inspection procedures for this area are deter-mined to be adequate.
An IE information notice has been issued relating to the tank and heat exchanger weld problems.
D.
Civil and Structural Construction 1.
CAT Findings Deficiencies were identified with the untimely and less than comprehensive corrective action taken to resolve concerns regarding the adequacy of structural fill test data records, insufficient torquing of high strength bolts in the Hydraulic Control Unit (HCU) framing, rags found embedded in a concrete placement, material found in the rattle spaces immediately around the containment building, and cadweld operator tensile testing frequency requirements not being met and the adequacy of corrective action previously taken by the licensee to resolve i
this same issue.
2.
Assessment The specific deficiencies mentioned above had not been pre-viously identified by the regional office.
The region's inspec-tien reports indicate that the soil records for the ultimate heat sink, dams, and dykes have been reviewed.
There was no specific inspection record that the records of structural fill under the power block had been reviewed, as expecttd.
The region's general review of the Illinois Power Company's Over-inspection (IPOI) Program criteria for inspection of structural steel was adequate and would not have served to identify that
$11. implenuntation for selection of the scope of IPOI's hardware coverage, relative to the HCU framing, was insufficient.
5 I
a: !,p '
n Ca Concrete placement work was reviewed by the region. The rags found in the concrete placement is considered an isolated case.
Cadweld travelers were reviewed by the region for conformance to the procedures, but apparently not with the specifications or FSAR commitments, which are different from the procedures.
The inspection program does require that FSAR commitments be consi-dered and, therefore, this deficiency should have been found by the region.
The inspection of the cleanliness of the separation (rattle) space is not specifically directed by applicable inspection procedures, but would have been identified, if included in the region's inspection sample, 3.
Recommendations The geotechnical/ foundation, structural steel, and reinforced concrete construct _fon inspection procedures are adequate.
An evaluation will be made by 01/RCPB regarding emphasizing cleanliness of building separatica (rattle) space in the appli-cable inspection procedures.
The region should monitor the licensee's resolution of the CAT findings relative to the records of structural fill under the power block and ensure that inspection program requirements are satisfied in this area.
E.
Material Traceability and Control 1.
CAT Findings Lack of traceability was found for fastener materials, particu-larly for vendor supplied pump-motor and pumo-turbine assemblies mounted on skids. Also, deficiencies were found in traceability for fasteners on certain hangers and HVAC control panel cabinets.
2.
Assessment In CPS inspection report 50-461/85-23, the Region III inspectors checked procurement documents for technical adequacy, quality assurance program requirements and procurement activities.
No problems were identified in the licensee's procurement activities.
3.
Recommendatiom The construction inspection procedure for the area of procure-ment appears to be adequate.
The procedures for inspection of seurce and receipt inspection of vendor supplied equipment appear to be inadequate in the areas of fastener traceability.
Problems have been identified in several of the CAT inspections where vendor supplied fasteners are reviewed for traceability.
i In future revisions to inspection procedures, more emphasis will be placed on traceability including centrol of fasteners furnished with vendor supplied equipment.

Desion Chance Control 1.
CAT Findinos v
A high rate of discrepancies was found between the active ic.
change documents listed in the Document Management System (DMS) and the change documents posted with controlled copies of a piping design specification.
j Humerous discrepancies were identified in the filing and updating of procedures in the Civil and Structural i
Resident Engineer's copy of the BalcNin Associates (BA) i Project Procedures Manual.
The computer data base did not satisfy the BA QA Manual objective for an index system which will ensure the rapid and orderly identification and retrieval of records.
A number of documentation discrepancies were identified in Illinois Power Company Overinspection Program reports.
2.
Assessment Region III had previously identified unposted cetive change documents on design drawings in inspection reports 50-461/
80-006 and 50 461/81-005.
Superseded revisions of drawings which had not been removed from files were identified in inspection report 50-461/81 005 which also identified docu-mentation discrepancies on design drawings. Documentation discrepancies in traveler packages were identified in inspection report 50-461/84 017.
The inspection procedures (IPs) most likely to capture hours used in inspection of design change control and specify design document control are IP 37051/37051B Verification of As-Builts, and IP 37055/370558, On-Site Design Activities. According to the 766 Computer System data for CPS through April 30, 1985, a total of 25 staff hours had been expended on IP 37051B, which was 80 percent complete, and 20 staff hours had been expended against IP 370558, which was 10 percent complete.
3.
Recommendations The construction inspection procedures are adequate in the design change control area.
However, increased regional atten-tion should be given to verifying the updating of controlled procedures and design documents.
The implementation of a 1
computer data base which satisfies the objectives of the BA QA 1
Hanual should be verified.
In addition, the region's sample for their review of the IPOI program should include critical review of the data recorded on the Overinspection reports.

Corrective Action Systems 1.
CAT Findings A lack of control of entries into the licensee's Startup Punch List af ter turnover of systems for startup testing was found by the CAT.
The number of problems found with the limited NRC CAT sample of open items reviewed indicates that this matter requires additional licensee management attention.
The CAT identified a licensee failure to apply effective corrective actions in the area of document control for licensee QA audit findings.
The CAT found in several inspection areas that the licensee had dispositioned nonconformances use-as-is without provid-ing a basis to substantiate this disposition.
2.
Assessment In CPS inspection reports 50-461/84-21 and 85-03, the I
Region III inspector reviewed the Preoperation Testing Program.
No problems were identified with the licensee's program or documentation reviewed.
In CPS inspection report 50-461/84-17 the Region III inspectors reviewed the corrective action system in regard to allegations related to nonconformance documents disposi-tiened use-as-is and invalidated nonconformance docu-ments. No problems were identified during this inspection.
In CPS inspection report 50-461/85-35 the Region III inspectors reviewed the licensee's audit program.
Audit checklists, findings, corrective action and timeliness of response were reviewed for a saeple of audits. No problems were identified during this rtview.
Region inspections also indicate that the ef fect of corrective action in areas being inspected are also reviewed.
Report 50-461/84-17 issued a Notice of Violation in the area of document control for a drawing document control problem similar to the deficiency identified by the CAT inspection for updating of the construction Project Procedures Manual and the controlled copies of the mechanical piping specif t-cation.
3.
Recomendation The construction inspection procedures for these areas appear to be adequate for the intended scope.
Region efforts in the preoperation testing area should be expanded in regard to the i
itcensee's Startup Punch List.

REV.EW 0F CLINTON POWER STATION CONSTRUCTION INSPECTION REPORTS A.
Scope The inspection procedures itemized in IE Manual Chapter (MC) 2512 were reviewed as to which were applicable to the CPS construction site.
A 766 Computer System printout was obtained for the entire construction period which identified report numbers, inspection procedures, inspection dates, staff hours, percent complete, and completion status.
A review was conducted for which procedures were implemented against the inspection precedures requirements.
Attach-ment 11 presents a summary of the inspection manhours and completion status of the HC 2512 program for CPS and Attachment III is a more complete inspection history for CPS based on the 766 Computer System data.
The data used for 'he assessment and summary data represents informa-tien in the 766 Computer System as of May 14, 1985.
The inspection reports prepared by the region and resident inspectors were evaluated to determine whether they included the required information, were l
sufficiently comprehensive, were issued in a timely fashion, and were prepared in accordance with HC 0610.
B.
Assessment The review of MC 2512 inspection procedures required to be imple-eented and the inspection hours recorded by Region !!! indicate that the construction inspection program is satisfactorily implemented and the program's completion status is commensurate with the stage of construction at the site.
In fact, Attachment II shows that over 70 percent of the direct dis'ciplinary inspection effort was for work observation which is concordant with current program policy to emphasize hardware inspections.
However, it appears that several inspection procedures in three areas have not been implemented based on the data available as of August i
26, 1985.
The three areas are instrumentation and control, reactor coolant pressure boundary pipe welding, and structures and supports welding.
The inspection procedures, categorized as Priority I in MC 2512 (dated September 15, 1981), without inspection time assigned to them are listed below and in Attachment II.
Instrumentation and Control 520658, 52064B, 52066B Rx Coolant Pressure Boundary 55071B, 550758, 55076B Pipe Welding Structures and Supports Welding 55153B, 55154B, 55155B 55156B, 55157B No significant problems have been identified in these areas by the region or the CAT; however, a number of isolated deficiencies have been found in instrumentation construction by both region and CAT hspectors. Although regional instrumentation inspections had been deferred for resolution of higher priority problems, completion of this portion of the construction inspection program requires regional emphasis.

- Inspections of structural welding, reactor coolant pressure bounde*y pipe welding, and NDE have been performed under the 5506xB, the
$517XB and the 570X0 series procedures, respectively.
Although there is some duplication of requirernents between the 550XX and the 551XX procedures, inspection requirements from both series were considered Priority I.
Regional management should assure themselves that all the pertinant inspection requirements for these welding areas have been or will be completed or have been satisfied through the NDE van inspection performed in 1984.
The review of inspection reports for CPS showed that, in addition to i
accomplishing the construction inspection program, much effort was devoted to allegation investigations and stop work order followup. A random' sample of 12 inspection reports (indicated below) shows that they were essentially being prepared in conformance with MC 0610.
The reports included pertinent information such as report number, docket number, inspectors, inspection summary, results, details of inspection, persons interviewed, and individuals present at entrance and e'xit meetings. The inspection reports provided sufficient detail to understand the issues and showed evidence of adequate technical content and review.
j HC 0610 suggests that inspection reports be issued 20 days af ter the last day of inspection or 20 days af ter the inspect.lon period ends as in the case of monthly resident's reports.
The following lists the reports reviewed and the total time elapsed from the end of inspection to issuance of the report.
This indicates, on average, the region is eeeting the MC 0610 requirement.
Days Inspection Report Performed To Number By Issue 84-08 Region 14 84-10 Region 26 84-29 Region 32 84-31 Region 26 84-41 Resident 17 84-42 Region 19 85-02 Region 21 85-07 Region 8

__19 AVERAGE 20.8 Report 85-08 details a special allegation inspection conducted by the region and was an especially lengthy report written by one inspector.
Discounting report 85-08, the region's average time for issuing reports is less than 19 days.
However, the reports do not list on the cover page the inspection procedures applicable to the inspection as suggested by MC 0610.
In addition, the region began performing the proprietary review in hcuse and eliminated the proprietary feview statement f rom the report cover letters in March 1985, commensurate with MC 0611 requirements.

C.
Recommendation Overall, the Region III office has performed satisfactorily in the implementation of the construction inspection program and procedures, i
Region emphasis on the completion of the 52XXX series of inspection I
procedures and an assessment of the structural and reactor coolant pipe welding procedures are required to ensure that these areas have been or will be adequately inspected.
The applicable inspection procedures should be identified in the cover page summary or in the detailed portion of the inspection reports.
V.
SALP REPORTS An analysis was made of the two most recent SALP reports, 1981-1982 and 1982-1984, for those areas that were common to both SALP and the CAT inspec-
' tion. Gensrally, the SALP reports reflect an average level of licensee performance with mostly Category 2 ratings and only one Category 3 rating for Quality Assurance during the previous SALP period.
However, the 1981-1982 SAtP report did not rata support systems or electrical power and distribution because of past weaknesses or performance not at least mini-mally acceptable.
It was during the 1981-1982 SALP period that problems identified by Region 111 resulted in numerous stnp work actions by the licensee. The effective and comprehensive efforts by the region in guiding the licensee through their recovery program led to the improved licensee performance documented in the 1982-1984 SALP report. This improved performance is generally supported by the CAT inspection findings.
The bases of the SALP ratings for both reports are well documented and supported by the region inspection report findings. A great deal of regional inspection effort went into monitoring and evaluating the licen-see's reco'very program starting in 1982 in consonance with the SALP recom-mendations, In most areas assessed in the SALP reports (safety related components, piping and support systems, soils and foundations, and instrumentation and controls), the regional and CAT findings were generally in agreement.
VI. OVERALL ASSES $HENT CONCLUSIONS A review of the CPS inspection reports, SALP reports, and 766 Computer System data indicates that, generally, the construction inspection program and modules had been s&tisfactorily im were written with the necessary scope,plemented.
The inspection reports depth, and technical content and on the average were issued within the suggested period. However, a few inspection modules require additional attention. An assessment by regional management should be made to ensure that inspection modules in the areas of instrumentation and control are completed in a timely manner and ensure that all pertinent inspection requirements for structural and reactor coolant pipe welding have been completed. An effort by regional management should be made to ensure the identification of appitcable inspection procedures in the inspection reports.

f c,.ic:..
z.S r ?,
A review of the CAT and regional inspection findings shows general agree-i ment.
However, the areas which require additional regional attention are i
the areas of document control (particularly the constructor's project procedures acnual, specifications and drawings, and associated design l
changes), electrical separation of raceways and vendor wiring in control room panels, the resolution of questions on the adequacy of the testing frequency of cadweld operators and on records of structural fill, and the control of entries into the IP Startup Punchlist, t'
A review of the latest $Al.P reports indicates that the Itcensee's perfor-mance has improved in several areas and this is supported by the CAT find-ings. This is indicative of the comprehensive and effective effort per-formed by the region in guiding the licensee to resolution of severe qua-lity problems in several areas of construction.
0verall, the regional efforts to oversee the construction activities at CPS are satisfactory. The implementation of the construction inspection program procedures also was satisfactory.
Regional management attention will be necessary to ensure completion of the construction inspection pro-gram in a few remaining areas and as the project moves into the testing phase.
