Licensee Action on Previous Inspection Findings (Open) Unresolved Item 281/80-13-04:
IE Bulletin 79-14 As-Built Discrepan-cie The licensee indicated that Periodic Test (PT) procedures would be used to inspect and adjust all spring supports prior to startup* of Unit These PT' s., were being updated to include newly installed spring supports *:
and snubbers identified by Stone & Webster letter of May 27, 198 A
typical Pipe Hanger Inspection PT,2-PT-43! for the Main Steam and Feedwater systems.,was examine These procedures only provide for verification of the location of the cold position indicating markers and the*actual cold positio The *inspector indicated that spring supports settings should be verified in both the cold and hot positions. This item remains ope The valve weight verification program was discussed in IE Report 280/80-22 and 281/80-25 and was identified as Inspector Followup Item 280/80-22-0 On June 27, 1980, VEPCO provided RI! with the following schedule for comple-tion of this program:
'.;
Inside Containment Outside Containment Field 11/10/80 8/20/80-2-UNIT 1 Design Review 11/25/80 9/20/80 Field 7/10/80 7/25/80 UNIT 2 Design Review 8/10/80 8/25/80 Completion dates for verification of valve weight with vendors-was not availabl The inspector indicated that this effort should be expedited based on the vendor valve weight problems identified by S-tlone & Webster on North Anna projec The current status of the valve weight verification program was discusse For Unit 1 approximately 20 percent of the valves outside containment had been field verified and none within* containmen For Unit 2 all valves inside containment had been verified and approximately 90 percent outside. * The~e items remain ope.
Unresolved Items Unresolved items were not identified during this inspectio.
(Open) !EB Bulletin 79-14, "Seismic Analysis for As-Built Safety Related Piping Systems", Unit 2 A meeting was held on July 8, 1980 at NRC headquarters between NRR, IE and *
VEPCO to discuss a program and schedule for cqmpletion of IE Bulletin 79-14 work efforts for Surry 2, specifically in relation to startup of this uni This program was outlined in VEPCO letter Serial No. 591 dated July 8, 1980. It was determined that supplementary clarifying information would be provided by VEPC Additional. required information was discussed during the onsite inspectio This additonal information has been provided by VEPCO in letter Serial No. 611 dated July 11, 198 The NRC response to the program and schedule outlined by the licensee has been provided by separate correspondenc (Open) I. E.Bulletin 79-02, "Pipe Support Base Plate Designs Using Concrete Expansion Anchor Bolts", Units 1 and 2 Stone & Webs;ter procedure STF-16, ~evision 2, "Inspection and Testing Program for Determining Baseplate and Anchor Acceptability for IE Bulletin 79-02", applicable to Unit 1, was examine The inspector questioned the use of back off torque to determine preload on wedge type anchors as spec'i~*.
£ied in paragraph 6.2.C.11. The licensee agreed that tightening torque was intended and indicated that the procedure would be revise No wedge bolts have yet been tested for preload. The inspector also questioned one of the definitions of. an inaccessible baseplate as where "Physical o*bstructioris preventing access to any of the anchor bolts" as specified in paragraph 6. The inspector later examined three baseplates in. the field that wer'e listed as "inaccessible" and observed that one or more anchors could be tension tested and all could be visually inspected. The licensee and con-tractor agreed that baseplates identified as inaccessible would be reviewed and received the maximum practical inspection effor ** '
-3-Ebasco procedure EEPC-005, Revision 5, "Inspection and testing of Existing Concrete Expansion Anchor Bolts", applicable to Unit 2, was also examined and discussed with site engineers.
. The following anchor bolt inspection and testing data packages were examined for completeness, type *of discrepancies noted and conformance to procedural requirements:
Unit 1 Line 6" -
WCMU - 39, Supports 10I8B3-6 and 1018B3-7 Line 2\\" - FP-8, Support 103IAI-6 Line 6" -
WCMU - 52, Support 10I8B3-1 Unit 2 Line 6"-RC-320, Support 17, plates A,C and D Line 6"-RC-340, Support HS Line 6"-RC-362, Support H8 Line 6"-RC-341, Supports H3 and H2 plate B Line 12"-RC-323, Support HlO, plates A, Band C Line 12"-RC-336, Support H2, plate B Line 6"-RC-367, Support H7, plate B Line 10"-RH-137, Support HIO, plate B
/
During the review of packages for line 6"-RC-320, Support 17, plate C and 12"-RC-323, Support HIO, plate B the inspector questioned their final dispo-sition. Although on one of these plates the tension tested anchor initially had slipped during testing and on the other the first two anchors tested had slippe*d, the disposition by the "Options Review Committe" was that the plates were acceptable without further testing. This action was based on these base-plates having subsequently become inaccessible due to high system/support temperature The slipped anchors had been replace However, without testing and/or analysis of the remaining anchors these baseplates can not be considered able to handle design load As VEPCO had already scheduled a review of all tension test reject packages to assure that adequate testing/
analysis had been performed, this was only identified as an Inspector Followup Item 281/80-29-01; Technical Evaluation of Expansion Anchor Tension Test Failures.* The licensee has reported subsequent to this inspection that the review identified four cases of this nature and all have been satisfactorily resolved. This item will be examined during a future inspectio The inspector witnessed the visual inspection and tension testing of a self drilling type anchor on Unit 1 MKS-143Al-4, Hanger Inspection and testing of an.chars is complete for Unit As of July 8, 1980, 94 anchors had been tested on Unit 1 with 5 tension failures. No devi-ations or items of noncompliance were identifie IE Bulletin 79-02 remains open pending completion of all inspections, testing analysis and modifications and subsequent reviews by the NRC.
