6. Safety-Related Pipe Support and Restraint Systems Review of Procedures / Specifications The NRC inspector reviewed Specification 5L340JS1002, Revision 11,

" Pipe Support Field Fabrication and Installation," and Standard Site Procedure (SSP) 9, Revision 4, " Pipe Support Installation," during this inspection period. SSP 9 and Specification 5L340JS1002 are used for Units 1 and 2. Review of these procedures, by the NRC inspector, indicate that deficiencies noted in NRC Inspection Report 50-498/86-23 and 50-499/86-21 have been addressed in the procedure, thereby enhancing the inspection attributes for spring hanger supports. Review of the procedures indicate that the manufacturer's instructions for fabrication / installation requirements have been incorporated. It was also found that adequate technical acceptance criteria and instructions have been include No violations or deviations were identifie Observation of Work and Work Activities (1) Dynamic Supports The NRC inspector observed the preinstallation activities by craft and engineering personnel on mechanical shock arresters (MSA). During this observation the craft made preinstallation checks for damage, rust, and other conditions that could interfere with proper operation. Craft personnel also made stroke adjustments which the discipline engineers observed. Observation by the NRC inspector indicated that work was accomplished in accordance with procedure The NRC inspector randomly selected 12 MSAs of different load classifications at various degrees of accessibility for a visual examination. The MSlM were inspected for the following attributes: MSAs were free from corrosion and deterioration, support plates, extension raus and connecting joints were not bent, loose, or otherw',e uut of specification; bolts, nuts, washers, locking devicts, and fasteners were tight and torque seal applied to indicate final inspection; correct model and load designation or classification; connecting joints and moving parts were free from foreign material such as fire proofing material, concrete residue, paint, and excessive dust and dirt that could obstruct proper operatio The licensee has provided adequate protection for installed MSA No violations or deviations were identifie .

(2) Small Bore Pipe Supports The NRC inspector performed a visual examination of five small bore pipe supports that were randomly selected from a computer printout. By visual examination, the NRC inspector determined that the following conditions meet the applicable requirements:

. Latest revised drawing and field change request (FCR)

changes were incorporated into the final as-built condition . Gaps between the piping and support appear adequate to allow thermal axial expansio . That the functional restraint direction was in accordance with the design drawing The licensee's work control system appears to be functioning properly and the installation of safety-related pipe supports are in compliance with licensee commitments, and applicable code Supports examined are as follows:

Reactor Coolant Pressure Boundary Piping Record Review The NRC inspector reviewed the completed records packages for eight circumferential butt welds on the 30-inch reactor coolant loo The records were reviewed for completeness and accuracy. The packages reviewed were for the eight field welds (FW0025 thru FW0032) on Loop No. 4. The individual records reviewed included: liquid penetrant, visual, radiographic and ultrasonic reports, weld process sheets, repair records and other.related process information. The welds are shown on isometric Drawing EFS-G-1018-B, Revision No violations or deviations were identifie t'

10. 10 CFR Part 21 Reporting CFR Part 21 Procedures

,

An inspection and review of site documents was made in order to verify that the requirements included in 10 CFR Part 21 are transcribed into project documents and that the process functions adequately. The following was noted:

. The basic requirement for posting of Part 21 documents is performed by the' licensee's project engineering; Bechtel also has procedural requirements for the same. A tour of the site

indicated that there was adequate posting. In addition, NRC Form 3 was posted in the same location . SSP 46 is the governing procedure for generating site requisitions; however, the specific requirements for the inclusion of Part 21 requirements into requisitions or purchase orders is outlined in Project Procurement Procedure 3.2, " Bid Requests for Purchase Orders." Purchasing agents also have standard listings of requirements that they are required to verify in preparing the purchase order. Randomly selected safety-related purchase orders were reviewed for inclusion of the statement that rovisions of Part 21 apply. It was also noted that SSP 99, p' Purchase of ' Commercial Grade' Items," has instructions for applying Part 21 requirement . When materials arrive on site, the following procedures are used for guidance:

. The base document that nonconforming items from all of the preceding procedures are evaluated to is PLP-02, " Reporting Design and Construction Deficiencies to NRC." This licensee document contains the requirements for review, evaluation and reporting on any item of nonconformance under the requirements of 10 CFR 50.55(e) and/or 10 CFR Part 2 There are adequate controls to assure that the reporting, disposition, evaluation, and records management are adequate and meet the requirements of the regulations. Nonconformances which meet the criteria for reporting to the NRC are subsequently reviewed by NRC inspectors and documented in NRC inspection report No violations or deviations were identified, Licensee Response and Action The purpose of this review was to verify that the licensee is receiving all Part 21 reports relating to STP. The review was also performed to determine if the licensee has implemented corrective actions where appropriate. The. licensee has received and addressed those Part 21. reports that were applicabl Part 21 No. 8400551 was never received by the licensee. The licensee was reviewed and compared this Part 21 with IE Information Notice (IEN) 83-72, Equipment Environmental Qualification (NEEQ)

Notice No. 19, which appears to be identical. IEN 83-72 does not appear to apply to ST Listed below are the Part 21 reports that were reviewed:

Safety-Related Structural Steel (Unit 1) Records Review The NRC inspector selected structural steel records based on observation of completed work in the field. The selection was made from Unit 1 MEAB and the isolation valve cubicle (IVC). The selection consisted of nine structural joints with 30 bolted connection Review of records indicated that the licensee system for preparing, reviewing, and maintaining records is functioning properly, and that selected records reflect work accomplishments consistent with procedure There were no serious problems; however, HL&P records review group identified some deficiencies in the room turnover area for the OGB. The deficiencies were identified in the mapping of the structural steel. There was a lack of direction on whether field engineering or QC was to verify that mapping was complete for turnover, resulting in some connections not being inspected. The deficiencies are being corrected and the structural program enhanced to prevent these deficiencies for future room turnover Documentation reviewed are listed below:
