/D lrs-/s 9" o&te Signed Scope:
This routine, unannounced inspection was conducted in the areas of Inservice Inspection (!SI) including review of ISI program admini-strative procedures, review of NOE procedures, observation and review of activities associated with NOE. examinations, revtew. of ISI examination data, and discussions and reviews of activities associated with NRC Bulletin 87-01 and previously opened item Results:
In the areas inspected, violations or deviations were not identifie The licensee has very recently issued a revised !SI inspection manual that includes both new and revised administrative and NOE procedure The administrative procedures establish a more comprehensive control of !SI activities and the NOE procedures, in most cases, are an improvement over previously used procedure The licensee has an adequate, comprehensive, pipe wall thinning detection plan in place, as evidenced by the recent detection of excessive wall loss rates in recently replaced 90 degree elbows on the suction side of both the A and B main feedwater pumps in Unit The wall loss was detected through normal application of the inspection plan *

Licensee Action on Previous Enforcement Matters (92702) (Open) Unresolved Item 281/86-34-02, QA records do not agree with visual examination conclusions. Refer to Report No. 50-281/88-15 for background information and licensee commitment The 1 icensee agreed to research historical documentation for the Unit 2 reactor vessel outlet nozzles in order to try and determine what the physical configuration of the inside surface of the nozzles is suppose to be according to the fabrication documentatio The licensee has researched the QA/QC documentation including a review of radiographic fil The results of the documentation search was reported by memo, Innsbrook - 3NW, dated September 14, 198 The inspector reviewed the memo which basically concludes that due to the manner in which the examination reports were completed that the records review did not conclusively establish the condition of the inside surface of the nozzles over the entire required surfac *
The review fulfills one of the commitments agreed to by the licensee however, until the remaining commitment is satisfied this item will remain ope (Open) Unresolved Item 281/86-34-03, Reactor Nozzle Indications -
Refer to Report No. 50-281/88-15 for background information and licensee commitment The licensee committed to establishing documented assigned respon-sibility for the technical review of in-process ISI examination reports and for a technical review of fi-Ral ISI reports.

This procedure is being utilized to obtain_the.thickness reading required by the licensee's inspection pla The inspector observed approximately 1500 thickness readings being taken on the Unit 2 items listed belo The inspector also reviewed certification records of equipment, materials, and NOE personnel being utilized during the examination of these item Test Location 2-FW-PSFT-3 14" - WFPD-126-901 to 18"- WFPD-101-901 2-FW-PSF2-30 14" - FW Sketch 11548-WFPD-15 11546-WFPD-18
- The inspector conducted an independent verification on several of the thickness readings taken on the above test location The verifi-cation readings were made following the completion of the examina-ti ans conducted by 1 i censee personne 1 and with the use of the licensee's equipment, couplant, and calibration bloc The verification readings obtained were within an acceptable tolerance range although minor deviation were noted that could be attributed to transducer placemen The inspector reviewed the thickness data and associated records for a sample of test location The data was reviewed to determine whether the reported thickness was consistent with the data being obtained in the fiel The data was also reviewed to determine compliance with requirements for examination record Discussions with licensee personnel and a review of the past completed examination results shows that replacement of several items has been necessar The very recent discovery of excessive wa 11 thinning rates in recently replaced 90 degree elbows at the suction side of both the A and B main feedwater pumps in Unit 2, which was detected through the normal application of the plant inspection plan, indicates that the plan is functioning adequatel Discussions with the Project Engineer regarding the pipe wall thinning discovered in the relatively new elbows at the main feedwater pumps indicated the elbows have been in service approxi-mately 1.2 years and that the growth rate of the wall thinning

mandates the replacement of these two elbows prior to plant startu The Project Engineer indicated that the elbows will be replaced with the same type material that is currently in place due primarily to the availability of the materia An immediate examination of the same location elbows in Unit 1 is to be made, however this had no been accomplished by the end of this inspection. Also, the licensee intends to conduct a study to determine if the material now in use at these locations should be replaced with a different type materiaJ and/or if the system design needs to be altered in order to eliminate the excessive wall loss at these locations in the futur Within the areas inspected, no viol at ions. or devi ati ans were identifie.
