Draft Report for Evaluation of W ASME Section XI Subsection IWE 1998 Torus Inspections, dated July 22,1998.

BACKGROUND IWE inspections were performed on the Torus bottom interior surface and the lower portions of the downcomers during the 1998 refueling outage. These areas are normally submerged and access was provided during the draining of the Torus for installation of new RHR and Core Spray strainers. The inspections were performed in parallel with sandblasting and re-coating the Torus bottom as part of the CS and RHR strainer replacement EDCR .

thickness for the Torus bottom p W is CI eel plates used to construct the Torus sh with no significant margin over the design thickness. To assure that the Torus shell remained within design specifications, wall thickness was verified as part of the re-coating effort.

D.G ir r ior/M.Dugan VYM 98/132 Page 2 of 3 The Design Engineering Mechanical Group was asked to provide assistance in developing a scheme for UT inspections on the Torus external shell to support the re-coating effort and to satisfy ASME Section XI, Subsection IWE requirements.

DISCUSSION Inspections Reference(b) outlined the proposed strategy for disposition of ASME Section XI, Subsection IWE, findings in the Torus. The general plan was to perform a initial visual inspection, assess the findings, and then formulate a detailed plan to address both the possible wall loss at locations of degraded coating and for long term monitoring of the Torus external shell and vent header corrosion.

The inspection efforts performed were as follows: Visual inspections of the interior surface of the bottom half of the Torus were performed, see reference(c). A limited number of specific locations were identified with surface corrosion and a significant number of previous coating repairs were identified and tabulated on a per bay basis. Three groups of UT data for the Torus bottom shell were taken based on the visual inspections. The first group were full coverage test strips on the bottom of two bays. The purpose of the test strips was to assess variations in plate thickness and to assess the amount of wall loss attributed to the sandblasting efforts.

The second group was a set of permanently marked discrete locations on the exterior of the Torus. These locations are intended for long term thickness measurements to monitor general corrosion of the bottom of the Torus shell. Given that the new coating will mitigate future corrosion, the 16 to 18 discrete locations in each bay will allow for long term UT monitoring for general corrosion of the Torus shell without draining the Torus. The third group are external UT inspections at local areas of coating degradation identified in the as-found visual inspections and a sample of the areas accessible from only one side (under the Torus baffle plates).

Evaluation of Data Reference(e) was developed to provide acceptable corrosion limits for the Torus and vent system. It is based on the analyses and modifications performed by Teledyne Engineering Services (TES) under the GE Mark I Program. The TES acceptance criteria were based on the maximum accident pressure of 44 Psi. Reference@)did not consider the ASME code design pressure of 56.Psi. V.Y. ER 97-0307, reference (9) was written to reflect the fact that the TES calculation did not consider the ASME code design pressure. The ER also required that VYC-1032, Revision 0 be revised to reflect the 56. Psi. ASME code design pressure.

The thickness data was assessed against original design code requirements and analyses in reference(h). Th thickn- were found to be at code required thickness margin exists at the Torus bottom cent VYC-1032 is in the process of being revised to retlect the 56. Psi. code design pressure. hen the revision is complete, it will provide acceptable corroded thickness for the Torus shell based on the ASME code design pressure.

D.Girrio r/M. Dugan VYM 981132 Page 3 of 3 CONCLUSIONS Reference(i) summarizes the inspection efforts and evaluation of the UT inspection data. It will be formalized upon completion of the revision to VYC-1032, reference(e). The following conclusions are considered preliminary until the revision to VYC-1032 is complete.

There were no significant areas of general corrosion/metal loss identified during the 1998 refueling outage. Isolated small areas of surface corrosion and coating damage were observed, documented, and evaluated. No significant wall loss was identified.

The entire bottom half of the interior surface of the Torus was sandblasted and re-coated during the 1998 refueling outage. Application of the new coating will mitigate future corrosion. Visual inspections performed during future refueling outages under ASME Section XI Subsection IWE requirements will insure the condition of the coating is monitored and repaired as required.

A permanent set of UT locations has been established on the exterior bottom of the Torus shell to provide a means for monitoring general area wall thickness without draining the Torus.

code design pressure. When the revision is complete it will provide corroded thickness limits and acceptance criteria consistent with the original design code, reference(f).

EVALUATION OF DATA PROWED BY VT-I, CONTAINMENT SURFACES (IWE)

DATA SHEET No: 804541-019 During RFO 21 IWE examinations it was discoveredtbat the Joint Seal at the concrete to steel interface on the 238' level ofthe containmenthad failed and there was evidence of corrosion in areas ofthe seal. As a teSulta portion of the circumference of the seal interface area was declared as augmented The joint seal itselfwasalso scheduledfor replacement dmingRF0-22.

At the start 0fRFO-22 the examinersperformed the reqmdVT-1 m o n s ofthe augmented area at the joint seal to &ternme- if any changes had occuned during the last operating cycle. The resultsofthat exmination reveal NO changes identified in the an- area Atter the W-1emnhtions were complete the process began for the joint seal replacement A band of paint was removed from the concrete floor up &e steel containmentappximately 6" wide for the full circumference. Tbe recessed area for the joint seal was also cleaned mpreparation for the new seal installation. At this point a VT-3 examinatomwas performed which identified a band of pitting that covered much ofthe 360degree circumference. A more detailed VI'-1 was ordered by the Responsiie Engineer to detail this area prior to paint/seal htdlation.

Thisjoint seal area was identified as an issue in the early 1990's. (ER-99-1594 deals with the issues Erom the 1990's resolutioa). In 1993the joint sed area was cleaned andpainted so as to fbm a paintjoint seal at the concrete to seal interhce. The areas identified during the -21 examinations were areas that were experiemingevidence of corrosion and paint loss in this paintedjointarea. Some ofthe paint was still intact and providing adequate protectionfor the steel it was covering.

The new areas of pittiugin the area of thejoint seal are a s a m of the coatingremod to white metal in this area This area was not previously identified during RFO-21 because it was an old area of pitting that hadbeen covered by the 1993 coatiugand hadnot experienced any further degradation. As aresult ofthe coatings being mmpletely removed ffom thisjoint area, this VT-1examination was able to map this region without the impedance ofany obstruction.

The areas of pitting are isolated to the general area ofthe joint seal interface between the con& and the steel. The pitting subsides as it mom up or down out of thejoint seal area. This was evi&nt whena portion ofthe steel slnface was exposed as a result of theremaVal ofa concretechip. 'The under slaface area exposed wasapproximately 9" wide and 3" deep inacrescent shape. The w o d case pitting is isolated to aband in the joint seal area from alqmximately !4" wide to approximately 1" wide andis descrii in the report as areas with general wastage and connected pitting All c o d o n identified within this report is Boundedby evaluation VYM 99/139.Based on thisevaluation all areas are well Withinthe reqkddesigu base metal thicknessesandare accqtable for continuedoperation as is.
