No tube plugging will be accomplished at this site ' due to insufficient tube stability factors as a result of flow peakin Evaluations, witn regard to flow peaking tube stability ratios comparable to the tube rupture at North Anna, show that the flow peaking effects in these steam generators are well below those at North Anna, according to the license Determination of which tubes may not be effectively suprorted by AVB's is still under consideratio Westinghouse has. been contracted to make this determination; however, historical eddy current data was not sufficient to adequately make the determinatio Additional eddy current data was taken during this outage for Unit 2 and is being forwarded to Westinghouse for further evaluatio A. formal report is expected from

Additional eddy current data is scheduled to be acquired during the Unit 1 outage in November 1988, and this data will be forwarded to Westinghouse at that tim Discussions with licensee personnel indicated that an ongoing dialogue between Duke Power Company and the NRC, with regard to other

areas of concern discussed in the bulletin, has existed since March 198 These additional areas of concern were not addressed during this inspection, b. Bulletin 88-05, and 88-05, Supplement 1: Nonconforming Materials Supplied by Piping Supplies, Inc. at Folsom, New Jersey and West Jersey Manufacturing Company at Williamstown, New Jerse Inquiries regarding this bulletin were made by the inspector in order to confirm that actions were being taken oy the licensee that will resolve the problems identified in the bulletin. The licensee is not required to officially respond to this bulletin until mid-July 198 Discussions with the licensee and a review of preliminary documen-tation supplied by the licensee shows that an action plan for the response to this bulletin has been established and is currently being pursued. Preliminary documentation indicates that to date four lots of suspect materials have been identified that contain a total of 38 items. Of the 38 items iaentified, four from each lot have been hardness tested and three of the items are in;talled, however, the three installed items are located in non-safety related system The licensee is still in the process of determining how much suspect material may be located at this s'se and plans to formally respond to the bulletin at a later date as stipulated by the bullet.i ._
