| |
| The RRI made a number of observations of electrical cable installations during the-inspection period.
| |
| | |
| The primary inspection effort was directed toward verification that the' cable installation crews are knowledgeable of the' site -procedures for such work and are following them.-
| |
| The RRI also.
| |
|
| |
|
| .
| | % |
| observed the' activities'of.the QA/QC personnel assigned to monitor the
| |
| ' | | ' |
| cable installation in order to ascertain their apparent level of capability and their diligence in monitoring the craft labor activities.
| |
|
| |
| The RRI noted, during observations of three different labor crews and four different
| |
| . | | . |
| QA/QC inspectors, that each crew and each inspector was following the respec-
| |
| ~tive~ procedures.
| |
|
| |
| The RRI inspected a random selection of cable trays for
| |
| '
| |
| . proper installation and for it?rpos from burrs and other sharp edges. The inspector also-initiated an inspection of the structural steel support
| |
| ; system.for the. cable trays in the Unit No. 2 spread-room.
| |
|
| |
| This latter
| |
| , | | , |
| effort is not complete due to the size'and complexity of the installation.

| |
|
| |
| The lug compression tools in use by the terminators were noted to be within their calibration period and were in good mechanical condition and correctly used during the observa-tion time.

| Safety-Related Piping System Installation The RRI made limited observations of piping component handling practices during the inspection period and determined such activities to be consistent with project procedures and good practice. During the period, the RRI observed welder APL working on pass number six of weld FW-6 as identified on Isometric SI-1-090 for line number 10-SI-1-105-2501R2.
| |
|
| |
| The welder was observed to be following Welding Procedure No. 88025 on this pass and using weld rod identified by. Heat No. 762550.
| |
|
| |
| The RRI has verified, during
| |
| . several previous inspection periods, that the weld procedure and the welder have been certified in accordance with ASME Section IX.
| |
|
| |
| The RRI obtained and revi'ewed the Certified Material Test Report - for Heat No. 762550 and verified that the material met the requirements of ASME'Section II and that the weld material was appropriate for the base metal involved.
| |
|
| |
| The RRI also examined the following radiographs for completed safety Class 1 and 2 welds as denoted by the last number in the line designation.
| |
|
| |
| The radiographs indicated that the welds conformed to the requirements of ASME Section III for the applicable class. The radiographs themselves met the quality requirements of ASME Section V.

| that many of the plant piping systems had been categorized as Class 5 and that the licensee had commited to applicable portions of Appendix B as required by RG 1.29 and the FSAR. Additional research, particularily of Project Specification MS-46A for safety-related hanger / supports and MS-46B for nonsafety hangers / supports, indicated that the Class 5 devices had been placed into the nonsafety specification and that no quality assurance requirements had been imposed on either the vendors or the field work. The RRI's research indicated that a substantially complete program for design, material selection, fabrication and installation is required through the governing code, B31.1 Power Piping Code, and the various references including the specifications of the American Institute For Steel Construction (AISC).
| | t |
| | |
| The RRI considered this to be an item of noncompliance which was provided to the licensee by a Region IV letter dated June 23, 1980.
| |
| | |
| The RRI also inspected the Class 2 and 3 hangers / supports for conformance to the design drawings, reviewed available documentation, and further evaluated the-designs versus the governing ASME Code requirement, Section III, Subsection NF.
| |
| | |
| Seven of eleven drawings contained the following notes:
| |
| (1) All tolerances in accordance with QCP #2A001 U.N.O.
| |
| | |
| (2) Fab. Procedure is FH-101 (3) All products designed in N-4 accordance with EPL File No. 1, Rev. 12.
| |
| | |
| Since all of drawings carry the Brown & Root log and were issued "for construction," it appeared that the above notes were applicable to the field fabrication and installation efforts.
| |
| | |
| The RRI was unaware of these procedures and attempted to obtain them from the site document control center.and the QA library of site procedures only to find that such pro-cedures were apparently not on site. Discussions with cognizant licensee personnel indicated that the drawings involved were actually ITT-Grinnell drawings converted to Brown & Root procedures. The licensee stated that the Brown & Root General Piping Procedure CPM 6.9 contained both tolerance and fabrication information that was applicable to the Brown & Root work effort.
| |
| | |
| The RRI indicated that an apparent item of noncompliance with Criterion V of Appendix B had occurred since it was evident that.the field wack had not been accomplished in accordance with procedures referenced in applicable drawings. The procedures could not have been followed since they were not on site. For the record, the RRI would note that his inspections of hangers and supports have not shown any apparent technical problem with the hangers on supports as a result of this noncompliance.
| |
| | |
| The RRI noted, during the inspection of installed components and the subse-quent drawing review, that a few of the observed attachment welds of various members to their base plates did not appear to conform to the
| |
| | |
| .
| |
| .
| |
| . | | . |
| | | i l |
| *
| |
| ..
| |
| detail requirements of Subsection NF of ASME Section III.
| |
| | |
| The most notable situation was where "I" beams had been tee welded to the base plate and there was generally no weld on the inside edge of the flange.
| |
| | |
| The Code bas one of two applicable requirements, depending on whether the joint is considered by the designer as a " plate and shell" or as a " linear type" joint.
| |
| | |
| In the case of the plate and shell type, the Code requires a full fillet joint. As observed, the flange faces were welded to the base plate and in order to have a full fillet configuration, the inside of the flange as well must also be welded to the plate.
| |
| | |
| In the case of the linear type support, the NF referenced paragraph XVII-2452.1 requires that side and end welds be returned around the corner at the end or side.
| |
| | |
| In the case of the "I" beam design, the weld on the flange faces would have to turn the end of the flange and go down the inside of the flange two times the specified weld size, or typically about
| |
| ,
| |
| one-half inch.
| |
| | |
| The RRI also noted other installations and drawings utilizing square structural tubing wherein the weld in several instances was only along two sides of the tube.
| |
| | |
| The Code appears to require an all around weld if the support is in the plate and shell category and the weld go around the corner of the box on to the currently unwelded faces at least twice in length of the specified weld size, again typically a half-inch.
| |
| | |
| The RRI noted during a records review of several of the component supports, that while in some instances the QA/QC inspection of the welds had been documented, none of the supports involved in the inspection were finally inspected.
| |
| | |
| Most of the items selected did not indicate that any weld inspection had yet taken place.
| |
| | |
| Since the QA/QC status of the selected supports was relatively incomplete, the RRI does not know what the final acceptance decision by QA/QC is and therefore this will be considered to be an unresolved item.
| |
| | |
| 7.
| |
| | |
| Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items, items of non-compliance, or deviations. One such item disclosed during the inspection is discussed in paragraph 6 and will hereafter be refered to as " Weld Configuration of Component Supports."
| |
| | |
| 8.
| |
| | |
| Management Interviews The RRI met with one or more of the persons identified in paragraph 1 on June 4, 10, 17, 18.and 25, 1980, to discuss inspection findings and the licensee actions and positions.
