SUBJECT:
JUNE 28, 1988 MEETING WITH GPU NUCLEAR CORPORATION (GPUN) TO DISCUSS MATTERS RELATED TO THE OYSTER CREEK-12R OUTAGE IGSCC INSPECTION / STRESS IMPROVEMENT PLANS On Tuesday, June 28 ISE8, a meeting was held at NRC, One White Flint North, Rockville, Maryland, with GPUN to discuss matters related to the Oyster Creek-12R Outage IGSrc Inspection / Stress Improvement Plans. Attachnent 1 is the list of individuals participating in the discussion Attachnent 2 is the lie.ensee's agenda. The folicwing is a suranary of the significant items discussed.
The licensee presented their plans and indicated that they propose to inspect 58 inspectable welds during the 12R outage. This would leave 102 welds (this includes 40 uninspectable welds) that will not be inspected after the 12R outage. This does not include most of the reactor water cleanup system welds outside of the drywell. The licensee also discussed GPUN's 1GSCC mitagition program in detail (see Attachment 2). GPUN also indicated that during the 13R outage they intend to replace all four isolation condenser penetrations including 4-8 welds inside the drywell ar.d all piping cutside drywell on 75' Elevation with IGSCC resistant naterial.
The licensee concluded that the inspection plan for the 12R outage was adequate to detertnine if n:ajor IGSCC problem exists at Oyster Creek. GPUN also concluded that (1) good water chemistry in cycles 10 and 11 and hydrogen water chemistry in cycle 12 significantly reduces potential f or new cracks and growth rate of existing non detected cracks, if any, (2) their plans minimizes and balances nan-rem exposures over three outages and (3) all welds will have been inspected at least once for IGSCC by the end of 13R except four recirculation safe ends (eight welds-to be inspected in 14R) and 13 RWCU welds cutside the drywell (to be inspected in 14R).
The staff advised the licensee that they shculd (1) provide a con >parison of GPUN's program with Generic Letter 88-01 at the end of 12R, 13R and 14R cutages. GPUN should also include previous inspection results and indicate sarrple size used in the inspection, (2) discuss ccrrpensating measures for welds thtt have not been inspected including the welds in the reactor water cleanup system outside the drywell, (3) discribe how Oyster Creek's leakage detection system meets the requirements of Generic letter 88-01 and (4) commit to a sampling expansion program in accordance with Generic Letter 88-01 for the 12R cutage inspection, yf0 8807110487 800706 O
