On November 7, 1986, the licensee notified Region II of a potential defect involving a substantial safety hazard at North Anna Power Station Units 1 and 2. The potential defect was described as laminar indications or

" pipe," located in the webbing of the structural steel material used as support columns for the spray array system in the service water pond. The condition was first observed by qC during inspection of completed weld The licensee's followup volumetric, " ultrasonic" examination disclosed that a total of 21 columns exhibited this condition. The material in question was produced by Inland Steel Company (Inland) and purchased through Rockwell Engineering of Blue Island, Illinois. The licensee, with assistance from Inland, has determined that the defective columns were produced from material produced from heat number 17802. The defective columns have been removed and their replacement installed via Design Change (DC), Number 84-31-13, Revision 70, December 15, 1986 and Field Changes 350, 353 and 358. The inspector reviewed the aforementioned Part 21 report and determined it to be acceptabl Also, the inspector reviewed the aforementioned DC, and n elated QA/QC nonconformance report 86-81 " Column Replacement", records to verify that the corrective actions have been implemented as stated. This item is close . Service Water Reservoir Spray and Bypass System Welding (55050)

This work effort was performed as a followup to that documented in Report 50-338,339/86-26. At the time of this inspection, work activity was focussed on welding the tie-in, 36" pressure balanced expansion joints, on service water line WS-4-151-Q3. The licensee's submittal entitled

. . . Proposed Technical Specification Changes, S/N 86-102, dated September 12, 1986, states in part that, design, materials, fabrication, inspection and testing, of the buried piping, expansion joints and access hatches etc. , are governed by Class III requirements of USAS/ ANSI B31.7, 1969 Edition with 1970 Addenda. The aforementioned system has been designated as a QA Category I, structur Weld selected for inspection at this time were as follow Weld Type Status FW-61 36" pipe to Flange completed FW-62H Trunnion to Pipe hot passes in progress H501 Support Plate to trunnion completed These joints were examined to determine whether the following characteristics / attributes conformed to the requirements of the aforementioned code Weld surface finish and appearanc Weld reinforcemen Joint configurations of permanent attachments and structural supports, Removal of temporary attachments, arc strikes and welds spatte .

3 Finish grinding; verify absence of wall thinning, Absence of surface defects including cracks, laps, lack of penetration, lack of fusion, porosity, slag, oxide film and undercut exceeding prescribed limit ,

In addition, the inspector reviewed the performance qualification records of welders to verify that they had been, and were currently qualified to weld these components / piping in accordance with ASME Section IX code requirements. These welders were identified by stencil number: N-263,

-283, -288 and -31 Quality records of the filler metal material used at the time of this inspection were re /iewed to serify compliance with applicable code / standards requirements. The material was identified as follows:

Lot / Heat Size E7018 32604F/402J8331 1/8" 0 ER705-2 702907-12-5/F8902 1/8" 0 Other quality records of related components which were reviewed for content completeness and comoliance with applicable specification NAS-2045, May 31, 1985 were as follows:
