PDR.

ESR 97-00706 Rev. 0 ATTACHMENT B PAGE 2 The documentation included on the following pages verifies that the revised DLL computer program is giving the same results for the sample problems. The program was modified to accept nine hundred and ninety nin~e (999) ligaments. Also, " Pauses" were innyted to allow a longer viewing time of the error messages when they appear.

No computational areas of the program were revised, thus no changes in the results were expected or identified.

Ccrolina Power & Light Company ESR 9700706 Rev. 0 Brunswick Nuclar Plant Unit 1 Attachment D Engineering Evaluation Page 2 Core Shroud Inspection Plan Brunswick Steam Electric Plant, Unit No 1 Refueling Outage 11 (B112RI), April 1998

SUMMARY

OF Bil2R1 INSPECTION PLANS The scope of re-inspection for the Brunswick Steam Electric Plant (BSEP), Unit No.1 Refueling Outage 11 (i.e., B112RI) core shroud is based on several factors. Results of previous inspections performed on both BSEP, Unit Nos. I and 2, as well as results within the industry, are key inputs into the inspection plan.

Follow-up actions and commitments established from the last inspection are also included in the determination of the inspection scope. Guidance on shroud inspections and fiaw evaluation contained in the Boiling Water P.eactor Vessel Internals hogram (BWRVIP) documents BWRVIP-01, " Core Shroud Inspection and Flaw Evaluation Guideline, Revision 2," and BWRVIP-07, " Guidelines for Reinspection of BWR Core Shrouds," is also used.

Analysis of weld HI ultrasonic testing (UT) data from BSEP, Unit No.1 Refueling Outage 10 (i.e.,

B111RI), performed using only the remaining ligament of the core shroud plate, concluded that the H1 weld was qualified for one additional cycle of operation. Preliminary analysis has been performed which takes credit for the additional ligament from the reinforcing fillet weld The finalized analysis will demonstrate that weld HI has suflicient structural margin for additional operating cycle (s). Therefore, no inspections of weld H1 are currently planned for the B112R1 outage. However, if the additional analysis of weld H1 concludes that the weld must be re-inspected to assure operability for an additional cycle, BSEP will re-inspect the weld during the Bl12R1 outage. Since welds H2 and H3 were structurally repirced with 12 clamps during BSEP, Unit No.1 Refueling Outage 8 (i.e., B109RI), these welds no longer require inspection. Seven of the twelve weld H2/H3 repair clamps will be visually inspected, which will complete the initial irispection of all 12 clamps installed. Analysis of the B111R1 UT inspection results for welds H4, H5, H6A, H6B, and H7 concluded that these welds do not require re-inspection during the B112R1 outage.

No inspections of weld H2 shroud support legs are planned since inspection tooling and techniques have not been fully developed that will work on the BSEP type shroud. Since no flaws were found on weld H9 during BSEP, Unit No.1 Refueling Outage 9 (i.e., B110RI) inspection, this weld does not need re-inspection in the Bl12R1 outage. Each shroud weld is discussed in further detail herein with respect to inspection history, results, and analytical conclusions.

INSPECTION HISTORY In the B109R1 outage,100 percent of the outside and inside surfaces of weld H1 was visually (VT) inspected. Cracking was found on 74 percent of the outside surfaces and no cracking was found on the inside surfaces. Eight locations were also UT inspected, with the crack depths ranging from less than 0.3 to a maximum of'.7 inches. In the B110R1 outage,4 of the 8 areas UT inspected in the B109R1 were again UT inspected with no significant crack depth growth noted. In the B111R1 outage,100 percent of the accessible areas of weld H1 were UT inspected. This weld presents unique challenges to UT inspection since the shroud head hold down bolt lugs prevent access to most areas on the upper side of the weld. These lugs limited the overall UT coverage of the upper side of the weld to 18.8 percent. The UT was performed on the upper side of weld H1 in 28 locations uniformly distributed around the circumference of the weld. Cracking, initiating exclusively on the outside surfaces on the ring side of the weld, was found in 98.2 percent of the area with i

_._.m_m____.-____-----------..

Chrolino Pow:r & Ught Company ESR 9700706 Rev. 0 Brunswick Nuclezr PI:nt - Unit 1 Attachment D Engineering Evaluation Page 3 depths from 0.32 to 0.66 inches. No cracking was found initiating from the inside surfaces on the ring side of the fillet weld heat affected zone.

The lower side of weld H1 was UT inspected in 79.6 percent of the area. Twelve percent of the area was found cracked, with depths ranging from 0.18 to 0.67 inches. The guide rod brackets and core spray piping prevent access to some areas of the weld. Analysis of the data showed the weld has sufficient structural margin to operate for one cycle without consideration for the additional ligament from the reinforcement fillet weld CP&L has since measured the size of the fillet weld using the UT data and is currently performing additional analysis of weld H1 that includes the stmetural ligament from the fillet weld.

Preliminary analysis has concluded that weld H1 has sufficient structural margin to operate for multiple cycles before re inspection. Therefore, no inspections of weld H1 are planned for the Bil2R1 outage. The analysis justifying additional cycle (s) of operation for weld H1 will be submitted to the NRC as specified by BWRVIP-01 for plant specific evaluations.

i Welds H2 and 113 were structurally replaced with twelve clamps during the B109R1 outage; therefore, no inspection of these welds is required. In the B110R1 outage, two of the clamps were VT inspected with no indications noted. In the B111R1 outage, three of the clumps were VT inspected with no indications noted.

The seven remaining clamps will be VT inspected during the Bl12R1 outage, thereby bringing the total l

clamps inspected to all 12.

In the B109RI outage, weld H4 was 100 percent VT inspected on the inside surfaces and 45 percent on the outside surfaces with no circumferential cracking noted. At Pumps prevented inspection of the remaining areas on the otaside surfaces. In the BillR1 outage, UT inspection was performed on 100 percent of the accessible areas with 77.6 percent of the total weld covered. Circumferential cracking was found in 8.1 percent of the inspected area with depths ranging from 0.1 to 0.62 inches. The guide rod brackets, core spray piping andjet pumps prevented access to some areas of the weld. Analysis shows the weld is qualified to operate for multiple cycles.

In the B109R1 outage, weld H5 was 100 percent VT inspected on the inside surfaces and 45 percent on the outside surfaces with five circumferential cracks found. Two locations were selected for depth measurement and growth monitoring in future outages with the crack ends punch marked and depth measurements taken -

l with UT. The depths ranged from less than 0.3 to 0.6 inches. Jet pumps prevented inspection of the remaining areas on the outside surfaces. In the B110R1 outage, these two areas were re-inspected with VT and UT with no significant growth in length or depth noted. In the B 111R1 outage, UT inspection wa=

performed on 100 percent of the accessible areas with 76.8 percent of the total weld covered.

Circumferential c acking was found in 25 percent of the inspected area with depths ranging from 0.1 to 0.2 inches. The guide rod brackets, core spray piping and jet pumps prevented access to some areas of the weld. Analysis shows the weld is qualified to operate for multiple cycles.

In the B109R1 outage, weld H6A was VT inspected on 45 percent of the outside surfaces with no circumferential cracking noted. Inaccessibility prevented inspections on the inside surfaces. During the B110R1 outage, UT inspection was performed in three areas covering approximately 10 percent of the weld.

Circumferential cracking was found at two locations with the maximum depth being 0.35 inches. Jet pumps and guide rod brackets prevented inspection of additional areas. In the Bl11R1 outage, UT inspection was performed on 100 percent of the accessible areas with 76.6 percent of the total weld inspected.

Circumferential cracking was found in 5.8 percent of the area with depths ranging from 0.1 to 0.35 inches.

Analysis shows the weld is qualified to operate for multiple cycles.

Carolina Power & Light Company ESR 9700706 Rev. 0 Brunswick Nuclear Plant - Unit 1 Attachment D Engineering Evaluation Page 4 In the B109R1 outage, weld H6B was VT inspected on 45% of the outside surfaces with no circumferential cracking noted. Inaccessibility prevented inspections on the inside surfaces. In th B110R1 outage, UT inspection was performed in three areas covering approximately 10 percent of the weld. Circumferemial cracking was found at three locations with the maximum depth being 0.55 inches. Jet pumps and guide rod brackets prevented inspection of additional areas, in the B 111R1 outage, UT inspection was performed on 100 percent of the accessible areas with 77.8 percent of the total weld inspected. Circumferential cracking was found in 8.9% of the area with depths ranging from 0.19 to 0.52 inches. Analysis shows the weld is qualified to operate for multiple cycles.

In the B109R1 outage, weld H7 was VT inspected on 17 percent of the outside surface with no circumferential cracking noted, inaccessibility prevented inspections on the inside surfaces. In the Bl 11R1 outage, UT inspection was performed on 100 percent of the accessible areas with 76.8 percent of the weld inspected. Circumferential cracking was found in 1.6 percent of the area with depths ranging from 0.1 to 0.37 inches. Analysis shows the weld is qualified to operate for multiple cycles.

No mspections have been performed, or are planned during the B112RI outage, for weld H8. This weld presents significant accessibility challenges since access to the upper side of the weld is very restricted due to thejet pump diffusers, core spray p,iping and guide rod brackets. Access to the lower side of the weld has even more restrictive access due to the jet pump baffle plate and the need to disassemble fuel cells for access from the bottom head region. Additionally, no inspection techniques and tooling have been completely developed. While some inspection tooling is available, it will not woik at BSEP due to the clamps installed around welds H2 and H3. When the inspection tooling and techniques are available, CP&L plans to :nspect

' w weld consistent with BWRVIP guidance.

During the B110R1 outage, weld H9 was UT inspected in 100 percent of the accessible areas. A total of 99 percent of the weld was inspected with no cracking noted Analysis shows the weld ic qualified to operate for multiple cycles.

There currently are no inspection equipment or techniques available for inspecting the core support legs.

When these inspection tooling and techniques are available, these areas will be inspected consistent with BWRVIP guidance.

A summary of the inspection history and plans for each weld, and for the clamps, is described in Table 1.

1 INSPECTION SCOPE EXPANSION If any unusual findings are found during the VT inspection of the seven clemps, the remaining clamps will be

. inspected to determine the extent of any changes.
