Applicant Action on Previous Inspection Findings (92701) (Closed) Open Item (461/82005-03): Rockwell International Energy Systems Group (ESG) had discovered through testing that the heater leadwire routing areas of Post LOCA Hydrogen Recombiners manufactured by ESG might have
l reached temperatures higher than the leadwire insulation design rating.
i The inspector reviewed the corrective action taken by the applicant l regarding this issue.
Included in this review were the following items: (a) Letter 82ESG-086, Rockwell International to Baldwin Associates discussing the design deficiency in the recombiners and the recommended remedial action.
(b) Letter SLMI-11142, Sargent and Lundy (S&L) to Illinois Power (IP) stating that the modification recommended by ESG was an acceptable environmental qualification program. The Rockwell program complies with the CPS FSAR commitments, regulatory requirements, and CPS seismic requirements.

. . (c) P.O. No. C-13145 which covered the purchase of modifications kit, Rockwell International document No. N139T120058, "Clinton Station Skid Modification." This document provided the technical instructions to accomplish the necessary mechanical and electrical changes to qualify the hydrogen recombiners. Also reviewed were FECN 13004, CWR 17965 and the various travelers associated with the aforementioned CWR, which were written to install the modification kit to complete the qualification of the skid.
(d) Rockwell International final qualification report, Document No. 290QR000029, " Qualification Report for Rockwell International Hydrogen Recombiner Skid Assembly, Clinton Power Plant". The report establishes the qualification of the skids to the requirements of IEEE-323-1974(IEEE-383-1974 for wires), IEEE-344-1975, 10 CFR 50.49, and Appendices A & B.
The system was qualified for a 40 year life except for the pressure transmitters which were qualified for a 10 year life.
The analyses and tests described in the qualification report verified the adequacy of the hydrogen recombiners to perform their safety-related functions subsequent to a Loss-of-Coolant Accident.
Based upon this review, no violations or deviations were identified.
This item is considered closed.

Applicant Action on 10 CFR 50.55(e) Items No. (92700) a.
(Closed) 461/83006-EE (55-83-06): Structural steel as supplied by Rockwell Engineering has questionable welds on clip angles.
l The inspector reviewed several interim reports issued by the licensee during the original investigation. These reviews were documented in Inspection Report No. 50-461/84023(DRS). Closure of this item was pending the release of an Amended Final Report.
The inspector reviewed, for the purpose of closing this item, the following: (1) Chairman's Final Report and Recommendation for Closure, Lange to Connell (ARL-29-1A); l (2) Final Report to NRC, Hall to Keppler (U-10167); (3) Revision to Rockwell Fabricated Steel Member Matrix, Lange to Baldwin (ARL-35-1PC); (4) Change in Course of Action to Resolve 55-83-06 Connell to Lange (Y-21566); (5) Change in Requirements Under the I.P. Over inspection Quality l Program, Lange to Baldwin (ARL-36-IPC and ARL-37-IPC);

. . (6) Transmittal of Revised Matrix to Baldwin, Lange to Baldwin (ARL-39-IPC); (7) Review of Rockwell Steel Welding, R. A. Witt to H. R. R. Victor (SLSI-4752), Victor to Lange (Y-25203 and Y-73270); (8) Amended Final Report, Lange to Connell (ARL-94-IPC); Amended Final Reports to NRC (U-600074); and (9) The Identification of Additional Members Requiring Inspection, LangetoSullivan(ARL-45-IPC).
The review of these documents determined that the investigations conducted adequately identified the issue and determined the root cause. The corrective actions taken to correct the problem and to prevent recurrence were also determined to be adequate.
Based upon these reviews this item is closed.
No violations or deviations were identified.
b.
(Closed) 461/84011-EE(55-84-11): Pipe flanges installed in ASME systems for which no objective evidence exists that the flanges were manufactured and material procured under a program meeting the requirements of ASME (NA3700/NCA 3300).
The inspector reviewed the applicant's closure package for this item which included, but was not limited to, correspondence pertinent to investigation to locate flanges and thread-o-lets, the investigation plan, interim reports to Illinois Power Quality Assurance (IPQA) and to the NRC, a request for Sargent and Lundy (S&L) to perform an engineering review for the conditions of uncertified flanges installed in ASME Systems, correspondence concerning the replacement of installed flanges, documentation of training of Baldwin Associates (BA) personnel to ASME NA-3700/NCA-3800 requirements, final report to IPQA, review of documents initiated during the investigation, review of corrective action implementation and review of final report to NRC.
The review of this material indicated that 77 uncertified flanges had been installed in safety-related systems and were replaced.
176 flanges had been installed in non-safety-related systems.
, The stainless steel thread-o-lets manufactured from unqualified stock material were identified.
12 had been received on site. Ten were placed on HOLD and were downgraded for use on Non-ASME systems.
The two that had been installed were determined to be acceptable based upon jurisdictional boundaries of the ASME Code such that NA-3700/NCA-3800 was not applicable.
Based upon these reviews this item is closed.

. . No violations or deviations were identified.
c.
(Closed) 461/85007-EE(55-85-07): Because of misinterpretation of Contract Specifications K-2856 and K-2857, no horizontal supports were installed by Automatic Sprinkler Company of America (ASC0A) on horizontal runs of sprinkler pipe in safety-related areas. This deficiency could affect the functionality of nearby safety-related equipment components during a Safe Shutdown Earthquake (SSE) event.
The resident inspector reviewed the applicant's corrective action which included an Investigation Plan, interim reports to Illinois Power (IP) Licensing and Safety and the NRC, final reports to IP Licensing and Safety and the NRC. These documents, with regard to Regulatory Guide 1.29, Paragraph C.2, Hanger Calculations for Divisions 1, 2, and 3 Diesel Generator Rooms, were reviewed for accuracy and overspan qualification requirements specified in American National Standards Institutes (ANSI) B 31.1, 1980 Edition, Equation 11.
An additional inspection covering field walkdown and proper hanger locations and designations was conducted by a regional specialist and documented in Inspection Report ho. 50-461/86028(DRS).
Based upon there reviews this item is closed.
No violations or deviations were identified.
d.
(Closed) 461/85009-EE(55-85-09): Baldwin Association Resident Engineering (BARE) Civil / Structural Department's inadequate review design change documents, including drawing revisions. The purpose of the BARE review was to identify design changes, and to assure that travelers and procedures were revised as required by Baldwin Associates (BA) procedures. As a result of the design changes not being incorporated into travelers, the construction of the design changes was not accomplished.
The inspector reviewed the applicant's Investigation Plan, Interim Report to Licensing and Safety, Interim Report to the NRC, Safety Significance Evaluation, Final Report to Licensing and Safety, and Final Report to NRC.
During these reviews the inspector also reviewed ten Nonconformance Reports (NRC). A total of 23 were generated to document unincorporated structural steel modifications. BA Corrective Action Request (CAR) 257 was also reviewed.
The root cause, as identified by BA was a breakdown in the Resident Engineering Civil / Structural Design Change Review BA procedure BAP 2.41 established a documented program for the design review process.
This requirement had not been properly implemented by the Civil / Structural Department.
In order to prevent recurrence, a BA organizational change was instituted replacing the Civil / Structural Supervisor.
Based on these reviews this item is closed.

Functional or Program Areas Inspected a.
Review of Engineering Evaluations of Inaccessable Structural Structural Steel (92701/48053C) The inspector re-reviewed the over-inspection plan regarding structural steel items. Also reviewed was Sargent and Lundy's (S&L) Safety Significance Evaluation of identified inaccessible structural steel and S&L project instruction PI-CP-068, Over-inspection Progra!U.
The applicant's over-inspection plan was based upon a lot size sample determined by criteria established in sample plan (MIL-STD-105D).
Results of the over-inspection showed that no nonconforming identifiable attributes on accessible members had any safety significance. The presumption is that the same attributes, if identified on inaccessible members, would not be safety significant.
Based upon S&L's safety evaluation and evaluations performed under PI-CP-068 this indeed was the case. This item is closed.
No violations or deviations were identified.
b.
Site Surveillance Tours (42051C) The inspector toured selected areas of the site at periodic intervals during the report period. Those tours assessed the general cleanliness of the site; storage and maintenance conditions of equipment and material being used in site construction; potential for fire or other hazards and to witness the remaining construction activities in progress.
General plant cleanliness is continually improving. Painting has progressed to a point that the plant has taken on a nearly finished look.
No violations or deviations were identified.
5.
Exit Meetings (30703) The inspector met with applicant representative (denoted in Paragraph 1) throughout the inspection period and at the conclusion of the inspection on May 27, 1986. The inspector summarized the scope and findings of the inspection activities. The inspector also discussed the likely information content of the inspection report with regard to documents or processes reviewed by the inspector during the inspection. The applicant did not identify any such documents / processes as proprietary. The applicant acknowledged the inspection findings.
