Nondestructive examinations are performed by qualified examiners using licensee approved procedures. The Quality Assurance Group is actively involved with ISi. QA surveillances are performed by QA Engineers who are knowledgeable of the activity they have been assigned to observe.
DETAILS INSERVICE INSPECTION ISi PROGRAM (INSPECTION PROCEDURE 73051)
The Salem Unit 2 facility has completed its first 10-year inservice inspection interval and is now in the first refueling outage of the second 10-year inspection interval, first period. The facility's operating license, No. DPR-75, was issued on October 13, 1981, which was the starting date of the first interval. The governing code for the second interval is the ASME Boiler and Pressure Vessel Code Section XI, 1986 Editio The inservice inspection program plan for the first interval at Salem Unit 2 and the final report for each refueling outage were prepared by Southwest Research Institute (SWRI), the licensee's ISi vendor. The vendor, additionally, maintains all examination data generated during the interval. The licensee has decided to exert more programmatic control by preparing its second 10-year interval program plan and will, by the next refueling outage, maintain all examination data and prepare the outage final repor The plan includes examination selection criteria for Class 1, 2 and 3 components, a list of all included components, and the period of the interval and outage in which the particular component is scheduled for examination. Information is included in the plan to expeditiously locate previous examination results for review and comparison with current dat Examination criteria for augmented examination of the reactor coolant pump flywheel, steam generator and reactor coolant pump main flange bolting, and containment spray piping with wall thickness less than 3/8" are listed and include the basis for the requirement to examine each item. Also included in the program plan submitted by the licensee for approval to the NRC are eight requests for relief from ASME Code requirement A memorandum dated March 17, 1993, from the Senior ISi Support Staff Engineer provides guidelines for establishing and revising the outage ISi examination plan. It identifies how changes to the outage plan, deletions, substitutions, and deferrals are to be documented and entered into the computer data base. The guidance, eventually, will be proceduralized and incorporated into the program plan. Outage plan changes to date were verified to have been properly identified and documented as require The 10-year plan is in the NRC review process and has not yet been approve Conclusions By preparing its 10-year inservice inspection (ISi) program plan and assuming the maintenance of examination data generated during the second 10-year interval, the licensee has enhanced its control of ISi activities, including those of its ISi vendor. The responsibility for program plan preparation and maintenance of examination data generated during its first 10-year ISi interval was delegated by the licensee to its ISi vendo.0 NONDESTRUCTIVE EXAMINATION (NDE) IMPLEMENTING PROCEDURES (IP 73052)
Selected NDE implementing procedures were inspected to ascertain compliance with code and regulatory requirements, and for technical adequacy. The following procedures were included in the inspection:
VS 2.SS-IS.ZZ-0070(Q), Revision 0, "Dry Powder Magnetic Particle Examination" VS 2.SS-IS.ZZ-0075(Q), Revision 0, "Solvent-Removable Liquid Penetrant Color Contrast Examination" VS 2.SS-IS.RCE-0084(Q), Revision 0, "Manual Ultrasonic Examination of Ferritic Pressure Vessel Welds (Greater than 2 to 12 inches in Thickness)"
VS 2.SS-IS.ZZ-0088(Q), Revision 0, "Manual Ultrasonic Examination Using.
Longitudinal-Wave Straight-Beam Techniques" The procedure numbers listed above were assigned by the licensee to SWRI procedures that were incorporated into the licensee's ISi program. Each procedure was reviewed and approved by the licensee for use at Salem Unit Each procedure was determined to comply with the applicable ASME Code and regulatory requirements and, further, were determined to be technically adequate for their intended us Conclusion The licensee's review and approval of vendor nondestructive examination procedures prior to their use at Salem Unit 2 assures compliance with applicable requirements, and exerts additional licensee control of its vendor's activitie.0 OBSERVATIONS OF WORK IN PROGRESS (IP 73753)
During this inspection, the ultrasonic examination of welds on the Salem Unit 2 boron injection tank was in progress by examiners employed by SWRI, the licensee's ISi vendo A portion of the examination of the lower head to shell weld "B" was observed by the inspector to determine whether the examination complied with applicable code and regulatory requirements, and whether the examiners were properly qualified to perform their assigned dutie '
The calibration of the ultrasonic examination system for the 45 ° shear wave examination of weld "B" was witnessed as was the examination using 60° shear wave. The calibration and examination was performed in compliance with procedure VS 2.SS-IS-RCE-0084(Q),
Revision 0, also identified as SAM 2 - UT 15, Revision 0, Change 0, which is the corresponding SWRI procedure number. The examination team was comprised of two members certified to UT Level IT and Level II, respectively. Personnel qualification records verified that each examiner was properly qualified to perform his assigned responsibilit Data related to the weld examination was inspected and determined to clearly document the acceptability of the weld and to identify all portions of the weld that could not be examined because of access limitation Personnel Qualification/Certification Records In addition to the qualification records of the examiners responsible for the ultrasonic examination of the weld discussed above, records of the remaining ISI vendor NDE personnel were selected for inspection. The records were inspected to determine their completeness, and that they verified that the related personnel were properly qualified and certified in compliance with the provisions of SNT-TC-lA, the governing document. All information required by SNT-TC-lA was included, and the proper qualification and certification of the personnel was confirmed. In compliance with the licensee's program, all of the records were reviewed and approved by the licensee prior to the performance of NDE by the individuals represented by the record Quality Assurance (QA) Involvement in ISi Quality assurance activities for the refueling outage, including those associated with inservice inspection, were planned prior to the start of the outage. The plan assigns responsibility to various QA Engineers with respect to their area of expertise. The goal of the QA effort is to identify problems or potential problems before they develop into significant issues which challenge safety in proper program implementatio Three QA Surveillance Reports were selected for inspection to ascertain that appropriate attributes were included in the surveillance, that the results were clearly documented including problems identified and their resolution, and that the surveillance was performed by a qualified, knowledgeable QA enginee The following reports were inspected:
