: 4. Page 1 of 14 L-MT-18-013 Enclosure 1 NSPM NSPM concludes that the welds were performed under a 10 CFR 50, Appendix B, Quality Assurance program such that the canister integrity is otherwise assured. The welds were performed by qualified welders using qualified welding procedures. Structural Integrity Associates (SIA), an engineering consulting firm with over 20 years of experience resolving spent fuel storage issues which employs industry experts in the areas of structural analysis and materials engineering among others , reviewed the welding performed via available video records and determined that the welding was performed consistent with the qualified procedures. Welding procedures were qualified in accordance with Section IX of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. As required by the Code , a test sample was welded and destructively tested to meet specific minimum requirements for procedure qualification. The WPS was prepared subsequently based on specific values of the essential variables used to weld the procedure qualification sample(s) having acceptable mechanical properties.

The Code provides allowable ranges of the essential variables that can be used based on the parameters tested. Weld data sheets documented that the qualified and approved welding procedures were followed for all welds. Machine weld head video files (VIDs) were reviewed by the chief welding engineer at SIA who is a fellow of the American Welding Society, has a doctorate i n materials science engineering and 50 years of experience in the application of materials science to the electric utility industry , primarily in the nuclear power industry. The VID review examined the welding conditions used and determined , based on the chief welding eng i neer's extensive nuclear welding experience , that the welding arc length , the wire feed entry , the arc lengths achieved , and the mo l ten weld puddle and deposit cha r ac t eristics were consistent with expectations for the specified welding parameters. The eight tack welds and all circumferential closure welds (both for the ITCP and OTCP that were available for review) utilized the WPS SS-8-M-TN, Revision 10 , gas tungsten arc welding (GTAW) machine welding procedure. The use of the manual GTAW weld i ng procedure was lim i ted to local i zed repairs and for cleaning up the corners of the keyway welds. Manual welds had no arc video records for review; therefore , their review relied on viewing from long range shop floor cameras. It was determined that manual welding was used in some instances based on the observed arc shine. Based on the preceding discussion , NSPM concludes that the observations from the review of the weld head videos are consistent with the use of qualified welding procedures. RAI M-2 Provide the certified material test reports (CMTRs) for the weld filler material heats used in the closure lid welding for DSCs 11-15.

NSPM Response NSPM determined there is a reasonable expectation that the ITCP welds on DSCs 11-15 have an actual thickness of 0.25". The technical basis supporting use of a weld deposit thickness greater than the weld design dimension of 3/16" is derived from the following items: the actual phased array ultrasonic testing (PAUT) weld measurements for DSC 16, review of the VIDs for the ITCP welds on DSCs 13 and 16 by the SIA chief welding engineer , the weld design/geometry and component fit-up as well as the physical requirements to accomplish the weld per the qualified welding process using the same GTAW machine, and use of a limited number of welders. The NRC has previously reviewed and accepted the DSC 16 PAUT data including the understanding of the actual weld measurements by way of granting an exemption for DSC 16 on June 15 , 2016 (Agencywide Document Access and Management System (ADAMS) Accession No. ML 16167A035).

The technical basis supporting use of a weld deposit thickness greater than the weld design dimension of 3/16" is derived from the following items: the actual phased array ultrasonic testing (PAUT) weld measurements for DSC 16, review of the VIDs for the ITCP welds on DSCs 13 and 16 by the SIA chief welding engineer, the weld design/geometry and component fit-up as well as the physical requirements to accomplish the weld per the qualified welding process using the same GTAW machine, and use of a limited number of welders .
The procedures used for the welding and visual examination (VT) inspections are included as Enclosure 6 and 7, respectively. For the ITCP welds , the weld groove volume is small and the deposition rate nearly fills the groove with the root pass alone. The chief welding engineer noted that the weld root gap varied slightly around the circumference due to fit-up and unequal weld shrinkage as a result of root tacking (eight equally spaced tacks applied by machine welding). The small changes in weld groove volume resulting from the root gap variation appeared to cause small fluctuations in the groove fill observed on the plate side of the groove edge. The observations supporting this effect were minor variations from slight underfill to slight overfill at the plate edge during the root bead. During welding , the tungsten position frequently was adjusted to manage the molten deposit. The root bead crown appeared to be relatively flat and fused into the shell wall. It was noted that the welding arc was positioned approximately midway across the groove during root bead welding. The welding arc for the second weld bead was repositioned closer to the shell wall resulting in a deposit profile that is thickest at the shell wall tapering downward to the ITCP surface such that the molten material slightly washes over the edge of the ITCP. Weld pass 2 , the cap pass , clearly overfilled the groove. The completed weld geometry is a partial penetration groove weld having an unequal leg length fillet cap. The SIA chief welding engineer also noted that the deposition rates for all beads appeared consistent based on a visual assessment of the welding travel speed and molten weld puddle size. NSPM determined there is a reasonable expectation that the ITCP welds for DSCs 11-15 have an actual thickness of 0.25" because the weld groove height is 0.25" , the confirmation from the as-measured data from DSC 16 PAUT , the consistency resulting from the adherence to the qualified weld procedure and techniques, a lim i ted set of qualified welders using the same GTAW machine while implementing a controlled fit-up for the small weld groove volume , and maintenance of a consistent weld deposition rate. These considerations are supported by the PAUT measurements and assessment provided by the SIA chief welding engineer VID review of the DSCs 13 and 16 ITCP welds. RAI M-4 Provide the following: 1.

A more detailed assessment of the welding videos and weld data sheets beyond what is summarized in the exemption request Enclosure 3 is necessary [to] assess the analysis provided for DSCs 11 through 15.
Based on this expert review , NSPM determined that there is a reasonable expectation to conclude the closure welds performed on DSCs 11-15 are of sufficient quality to protect the health and safety of the public. This conclusion is based on the fact that the welding process used is expected to provide adequate quality welds , a video review confirmed that appropriate welding practices were used , the closure welds on DSC 16 , as found by the NRC , provide reasonable assurance of adequate protection to the health and safety of the public, and the flaws identified via PAUT of DSC 16 are considered representative of potential flaws in DSCs 11-15. A description of the SIA review is provided below. Enclosure 9 provides SIA report 1301415.402, Revision 0. This report documents a review of the welding procedures to determine if the welding process associated with the closure welds would produce suitable quality welds. The report concludes that the GTAW welds in DSCs 11-15 can reasonably be expected to be of good quality and free of in j urious defects. This conclusion is based on the characteristics of the GTAW weld , the controls outlined for the welding program , and the fact that the welds and base metals are austenitic stainless steels.

: 1. This report documented a review of the weld quality by using the available weld head videos. This report provides a sampling of typical welding practices across the industry. Evidence of good welds being applied is ample and dominates the video. DSC 16 was demonstrated through PAUT and analysis to be acceptable even though SIA concluded, based on the review of available video records, it had the greatest likelihood for defects. Appendix B to Enclosure 2 of the exemption request provided SIA report 1301415.405 , Revision 0. This report performed a qualitative assessment of the likelihood that the welds Page 5 of 14 L-MT-18-013 Enclosure 1 NSPM might contain unacceptable defects. The report concluded it was reasonable to expect the welds were free from l arge discontinuities based on many factors including the app l ication of a proven and robust welding system designed specifically to support these canister field we l ds , use of ductile and easily weldable base materials , and the use of so l id wire filler material designed for welding these base materials.
NSPM Response The requested documents identified as items 1 and 2 above are provided in Enclosures 8 and 9, respectively. The requested welding data sheets (item 3) , in addition to inspection results, are provided in Enclosure 10.
The report inc l uded a review of literature regarding generation of defects in stainless steel weldments and concluded that the likelihood for large defects was not supported. The report concluded the most likely lack of fusion (LOF) defects would be inte r mittent in nature and not expected to have a through thickness dimension greater than one weld bead. These conclusions were confirmed by the PAUT performed on DSC 16. Enclosure 3 to the exemption request provided SIA report 700388.401 , Revision 1. A summary of this report was provided i n Appendix C to Enclosure 1 of the exemption request. This report performed an evaluation using all available data including the shop floor videos and the available PAUT results to determine if the types and extent of flaw distributions found in DSC 16 were representative of DSCs 11-15. This report concluded that , based on the evidence developed by reviewing the videos and the rest of the available evidence , it was reasonable to conclude that the conditions determined for the closure welds in DSC 16 are representative of the welds in DSCs 11-15. The tabulated details for DSC 16 weld beads have been updated for the ITCP to separate the original start of bead 2 (VID-2) and the restart from the original keyway position after grinding (VID-3) and are provided below as Table 1 to better summarize the observations.

This information is needed to complete the review in accordance with 10 CFR 72.122(b). NSPM Response The weld head video clock was approximately 1 hour and 17 minutes beh i nd the shop floor video clock. This difference between the clocks account for the majority of the inconsistencies between start and stop times noted in the RAI. For the remainder of the inconsistencies , it should be noted that judgment was required to ident i fy the exact weld start and stop t imes because it had to take into consideration such factors as camera angles , stripper bead activities , etc. Furthermore , grinding was confirmed to have occurred in all cases where it was Page 7 o f 14 L-MT-18-013 Enclosure 1 NSPM identified during the weld head video review but not the shop floor video review. The initial shop floor video review inadvertently missed the grinding that was performed. The weld head videos and the shop floor videos were both used for the evaluation performed by SIA. The information sought from each information source is different and were never intended to be tracked against each other. Therefore, the time stamps for each information source were never synchronized nor were they intended to be synchronized. The information derived from the review of the shop floor videos and weld head videos was used to identify the types and extent of activities being conducted for each canister , and to corroborate these activities where possible.
 
The shop floor videos were used in a qualitative sense to infer weld related activities for the canister and were available for all canister welds except for the ITCP on DSC 12; however weld head VIDs were incomplete and portions were unavailable for review (i.e., DSC 11 and certain segments in several of the other canisters). The principal value was to examine the types and frequencies of weld-related activities to look for similarities or significant differences. In some cases , periodic grinding was apparent and in other cases , local weld repairs were observed. However, no significant differences were seen in work activity or frequency.

Table 1 - Updated DSC 16 Description of the ITCP to Shell Weld Beads Separating VID-2 and VID-3 [Note : VID-3 was a restart welded over the original keyway start of VID-2]
For the " Reasonable Assurance of Weld Integrity" analysis Enclosure 1 , Page 30 of 75 states the following: LOF [lack of fusion] defects of similar sizes and locations seen in DSC 16 are reasonable assumptions for the other ITCP closure welds. The assumptions made for the ITCP closure weld bounding analysis in DSC 16 are considered reasonable for all ITCP canister closure welds , the conditions of the ITCP welds are judged as similar for all canisters. Additional statements in this paragraph indicate lack of fusion defects that might form would likely be located on the vertical sidewall because of the weld groove geometry and because there is limited room to tilt the tungsten electrode towards the side wall. The lack of fusion defects in the sidewall of the ITCP weld on DSC 16 were modeled as a defect in the root pass or layer 1 of 2. It is unclear why weld layer 2 would not also contain lack of fusion defects. Weld head video is limited to DSCs 13 and 16 , and additional review of the welding process to qualitatively assess the potential for lack of fusion defects for the remaining DSC ITCP welds is not possible.

Regardless , the VIDs suggested a nearly vertical tungsten orientation that required the molten weld metal to flow to the side wall with sufficient heat to fuse the bottom of the machined groove to the shell sidewall.

NSPM The ITCP weld is 2 passes with a design thickness of 3/16" (0.188"). The maximum flaw size observed at the ITCP weld/DSC shell interface in DSC 16 was 0.09" according to the Phased Array Ultrasonic Testing (PAUT) results. Because ITCP weld video is limited to DSCs 13 and 16, additional review of the welding process to assess the welding practices and qualitatively assess the potential for lack of fusion defects for the remaining DSC ITCP welds is not possible. Based on the review of the welding video records in Enclosure 3, it appears that the ITCP weld joint would be susceptible to lack of fusion flaws at the ITCP weld to shell interface. Given the limited information provided on the ITCP welds and the combination of the weld joint geometry , unfavorable electrode position and the sluggish nature of the weld metal observed during the welding of DSCs 11-16 , it is unclear if the modeled lack of fusion defects in the ITCP weld would be representative of the possibility that lack of fusion defects located at weld to DSC shell interfaces could be present in both of the ITCP weld passes. Because it is not possible to assess through weld head videos whether DSCs 11 , 12 , 14 , and 15 may have lack of fusion defects in both weld passes that compr i se the ITCP weld, it is unclear whether the modeled flaw size of 0.14 inches would account for the potential for the ITCP welds to have aligned lack of fusion defects (i.e., lack of fusion defects in each of the two weld passes) located at the DSC shell to ITCP weld interface. Th i s information is needed to complete the review in accordance with 10 CFR 72.122(b). NSPM Response Enclosure 1 to the exemption request , Page 29 of 75, describes the applicability of the DSC 16 PAUT results and the structural analysis of those results to DSCs 11-15 (Enclosure 5 to the exemption request). As noted in the exemption request , NSPM determined that there is a reasonable expectation that LOF defects seen in DSC 16 are representative of the potential flaws in the ot h er ITCP closure welds. T hese conclusions were supported by SIA evaluations as more fully described in the response to RAI M-4 , which included the potential benefits of any learning curve. The following additional information regarding the ITCP welding is provided to support these conclusions.
Difficu lt ies with wire feed guide position.
Page 9 of 14 L-MT-18-013 Enclosure 1 NSPM During the review of the available video records , SIA noted several observations regarding susceptibility for LOF defects located at the DSC shell interfaces being present in both the ITCP passes (root and cap passes). The root is established using an open root welding technique and the welding torch is positioned on the lid side of the open root joint such that the root is bridged with molten material that washes onto the canister shell wall. This is a common practice for open root geometries to control the weld puddle and avoid dropping molten metal through the gap between the two pieces being joined and blowing out the root. If too much of the molten puddle is directed toward the lid side , then insufficient washing onto the sidewall occurs and LOF defects can occur along the shell wall. Review of the VIDs that captured the root passes of the ITCP for DSCs 13 and 16 (the only ITCP VID information available) observed a potential for LOF at locations around the circumference where the welding arc position did not r emain centered on the weld groove. The fixed radial position of the weld head coupled with out-of-roundness of the shell wall caused the welding arc to drift away from the shell wall. This behavior is due to a lack of concentricity between the can i ster shell and the radial posit i on of the weld head as it travels around the circumference. As the shell wall moved further away from the welding arc, the molten weld puddle does not properly wash onto the shell wall , and LOF is favored and the welding arc must be repositioned. This behavior is consistent with the observed intermittent LOF indications that were seen along the shell wall associated with the root pass in DSC 1 6 PAUT inspection results. The second bead or cap pass was deposited w i th the welding arc positioned closer to the shell wall as an expected good welding practice with the intention of facilitating good sidewall tie-in and to minimize any potential for LOF defects. The deposit was seen to build preferentially along the shell wall and tapers uniformly downward across the top surface of the root pass as it flows over the edge of the ITCP. The second pass will remelt a small amount of the top of the root bead and recast that material with the second bead. The second pass deposit on the shell side is clearly above the locations where the LOF was suspected. Consistent with the intended purpose of repositioning the welding arc , the results of the PAUT inspection on DSC 16 identified sidewall LOF defects located in the lower port i on of the weld commensurate with the root pass tie-in to the sidewall.

Further , all DSCs were welded using the same processes , procedures, equipment and welders. Shop floor video reviews confirmed similar practices were applied to all canisters. Thus , it is reasonable to expect that the welding arc positioning target would be simila r for all canister ITCP welds. The potential for alignment and stack-up of any LOF defects i s further reduced by the remelting which will occur when the second pass remelts a small amount of the top of the root bead and recasts that material with the second bead. From the SIA r eview of the shop floor videos , it was observed that DSCs 11-15 experienced a greater amount of rework during the welding process than was observed for DSC 16 for both the ITCP and OTCP. These details are tabulated in Enclosure 3 to the exemption request. The performance of rework is an indication that the weld i ng operators were alert to identifying unfavorable conditions as they developed during welding so that they could be corrected in-process. Therefore , it is reasonable to conclude that the probability for flaws in the closure welds of DSCs 11-15 should be no greater , and perhaps lower than DSC 16 due to observed in-process of the repairs to correct undesirable features. Page 10 of 14 L-MT-18-013 Enclosure 1 NSPM There were no observations suggesting that the second bead (cap pass) would produce additional sidewall flaws that might stack-up along the shell wall. To the contrary , significant and effective sidewall tie-in was observed at the shell wall for the second bead in both DSCs 13 and 16 ITCP closure welds. This effective tie-in was due to the closer proximity of the welding arc during the second pass. NSPM determined that there is a reasonable expectation that flaws would not stack up along the canister shell wall in successive weld layers. This determination is based on the consistency in welders and processes , and associated shift in welding torch position towards the shell wall for its intended purpose of improved side-wall tie-in. The improved side-wall tie-in from the second layer will minimize potential for any possible flaw stack up along the canister shell wall. Beyond this conclusion, NSPM provided additional analyses to evaluate flaws maximized to identify the maximum flaw size that can be tolerated at the design thickness of the welds while still meeting the acceptable design limits. PAUT examination on DSC 16 identified an actual weld thickness of 0.25" -0.40" and an actual maximum flaw height of 0.11" in the ITCP weld. This maximum flaw was extended to account for flaw uncertainties in DSCs 11-15 up to 0.14". The analyses determined that a connected ligament of 0.05" (e.g., 0.14" flaw in a 0.19" thick weld, 0.20" flaw in a 0.25" thick weld) is sufficient to meet the design limits. Thus , the flaws modeled in Enclosures 4-8 to the exemption request were based on the PAUT results for DSC 16 and expanded to account for flaw uncertainties.

, it is welded to the DSC shell and vent/siphon block with a 3/16" groove weld. However , the ITCP l i d groove (weld prep) is 0.25" minimum , and it was confirmed that the weld is also 0.25." Enclosure 1 (Exemption Request for Nonconforming Dry Shielded Canister Dye Penetrant Examinations) page 29 of 75 states: Page 11 of 14 L-MT-18-013 Enclosure 1 For the ITCP weld [ ... ]The analysis calculates the critical flaw size for a weld size of 0.25 inch per the PAUT results for DSC 16 (which indicated a distance between the root and crown at the canister wall from 0.25 to 0.40 inches) in lieu of the design thickness of 3/16 inch.

However , in the discussion of the results contained in Enclosure 6 , page 33 of 75 of Enclosure 1 states: The maximum modeled weld flaws for OTCP to DSC shell weld are 0.43 inch and 0.42 inch in height , which represents about 85% through-wall of the 0.5-inch minimum weld throat.

These statements appear to be provide contradictory information and it is not clear whether the ITCP weld is modeled as the minimum design thickness or as the minimum measured thickness from the PAUT results for DSC 16. This information is needed to complete the review in accordance with 10 CFR 72.122(b). NSPM Response The calculation provided as Enclosure 4 to the exemption request evaluated the critical flaw size based on the maximum radial stresses in the welds due to design loads. This analysis modeled a 0.25" weld. The calculation performed in Enclosure 5 to the exemption request evaluated DSC 16 flaw conditions. These analyses modeled the weld groove as 0.25"; however, the weld was modeled using the weld design thickness of 3/16". The detailed dimensions of the model are shown in Figure 4 of Enclosure 5 to the exemption request. Conservatively , 0.09" and 0.11" full circumferential flaws were modeled. Enclosures 6 , 7 , and 8 to the exemption request used the model developed in Enclosure 5 and , therefore , used an ITCP weld thickness of 3/16". Structural RAls RAI ST-1 Provide the following ANSYS files used to analyze DSCs 11-15 in Enclosures 6 and 7, including load cases Internal Pressure 2D-Axisymmetric model and Side Drop 3D-Symmetric model with extensions: .db , .inp, .err , .mntr, .out , .db, and .rst , and revise modeling descriptions presented in Section 4.1 of Enclosure 6 accordingly.

Modeling details regarding element type, distribution (mesh), flaw depiction, constitutive material properties , and loading in both 20 and 30 space are most directly presented in the ANSYS files themselves. As an example on the need for clarifying modeling details description , the staff noted that, on page 6 of the enclosure, the applicant states (underscores added): Initial ANSYS finite element iterations were performed by increasing all the four flaws by a very small length resulting in a negligible increase in plastic strain. l.!:l the second step very large flaws where considered (leaving only one element of the model connected at each flaw) resulting in excessive strain for the plastic side drop analysis.

NSPM Response The weld head video clock was approximately 1 hour and 17 minutes beh ind the shop floor video clock. This difference between the clocks account for the majority of the inconsistencies between start and stop times noted in the RAI. For the remainder of the inconsistencies , it should be noted that judgment was required to identify the exact weld start and stop times because it had to take into consideration such factors as camera angles , stripper bead activities , etc. Furthermore , grinding was confirmed to have occurred in all cases where it was Page 7 of 14
 
L-MT-18-013                                                                                    NSPM identified during the weld head video review but not the shop floor video review. The initial shop floor video review inadvertently missed the grinding that was performed .
The weld head videos and the shop floor videos were both used for the evaluation performed by SIA. The information sought from each information source is different and were never intended to be tracked against each other. Therefore, the time stamps for each information source were never synchronized nor were they intended to be synchronized . The information derived from the review of the shop floor videos and weld head videos was used to identify the types and extent of activities being conducted for each canister, and to corroborate these activities where possible. The shop floor videos were used in a qualitative sense to infer weld related activities for the canister and were available for all canister welds except for the ITCP on DSC 12; however weld head VIDs were incomplete and portions were unavailable for review (i.e., DSC 11 and certain segments in several of the other canisters) . The principal value was to examine the types and frequencies of weld-related activities to look for similarities or significant differences . In some cases , periodic grinding was apparent and in other cases ,
local weld repairs were observed . However, no significant differences were seen in work activity or frequency. This information was used as supporting information for the evaluations.
RAI M-6 Provide additional information to support the assumed flaw size and location of the potential lack of fusion flaws in the ITCP welds for the "Reasonable Assurance of Weld Integrity" and the "Additional Stress Margins in Welds" analyses.
For the "Reasonable Assurance of Weld Integrity" analysis Enclosure 1, Page 30 of 75 states the following :
LOF [lack of fusion] defects of similar sizes and locations seen in DSC 16 are reasonable assumptions for the other ITCP closure welds . The assumptions made for the ITCP closure weld bounding analysis in DSC 16 are considered reasonable for all ITCP canister closure welds , the conditions of the ITCP welds are judged as similar for all canisters .
Additional statements in this paragraph indicate lack of fusion defects that might form would likely be located on the vertical sidewall because of the weld groove geometry and because there is limited room to tilt the tungsten electrode towards the side wall. The lack of fusion defects in the sidewall of the ITCP weld on DSC 16 were modeled as a defect in the root pass or layer 1 of 2. It is unclear why weld layer 2 would not also contain lack of fusion defects.
Weld head video is limited to DSCs 13 and 16, and additional review of the welding process to qualitatively assess the potential for lack of fusion defects for the remaining DSC ITCP welds is not possible. In addition , the initial DSCs would have little to no benefit from any "learning curve" for the ITCP welds.
In the "Additional Stress Margins in Welds" analysis , the assumed flaw size of 0.14" is used for ITCP weld flaw-2 in Enclosure 6, "NU HOMS 61 BTH Type 1 DSC ITCP and OTCP Maximum Weld Flaw Evaluation ," AREVA Calculation 11042-0207, Revision 0.

L-MT-18-013                                                                                    NSPM Enclosure 1 However, Enclosure 3 Section 3.1.4.1 (page 3-9 or 142/461 of ML17296A205) states:
The video welding records (VIDs) reviewed for this weld did not show evidence of electrode tilt (working angle) towards the vertical sidewall to facilitate optimum tie-in to the vertical wall of the weld joint[ ... ]. Regardless , the VIDs suggested a nearly vertical tungsten orientation that required the molten weld metal to flow to the side wall with sufficient heat to fuse the bottom of the machined groove to the shell sidewall. The sluggish nature of weld metal flow (lava flow) and the issues encountered with maintaining the proper wire entry location due to the filler wire cast created variability in fusion conditions on the sidewall.
The ITCP weld is 2 passes with a design thickness of 3/16" (0.188"). The maximum flaw size observed at the ITCP weld/DSC shell interface in DSC 16 was 0.09" according to the Phased Array Ultrasonic Testing (PAUT) results . Because ITCP weld video is limited to DSCs 13 and 16, additional review of the welding process to assess the welding practices and qualitatively assess the potential for lack of fusion defects for the remaining DSC ITCP welds is not possible.
Based on the review of the welding video records in Enclosure 3, it appears that the ITCP weld joint would be susceptible to lack of fusion flaws at the ITCP weld to shell interface . Given the limited information provided on the ITCP welds and the combination of the weld joint geometry, unfavorable electrode position and the sluggish nature of the weld metal observed during the welding of DSCs 11-16, it is unclear if the modeled lack of fusion defects in the ITCP weld would be representative of the possibility that lack of fusion defects located at weld to DSC shell interfaces could be present in both of the ITCP weld passes . Because it is not possible to assess through weld head videos whether DSCs 11 , 12, 14, and 15 may have lack of fusion defects in both weld passes that comprise the ITCP weld, it is unclear whether the modeled flaw size of 0.14 inches would account for the potential for the ITCP welds to have aligned lack of fusion defects (i.e. , lack of fusion defects in each of the two weld passes) located at the DSC shell to ITCP weld interface .
Th is information is needed to complete the review in accordance with 10 CFR 72.122(b) .
NSPM Response  to the exemption request, Page 29 of 75, describes the applicability of the DSC 16 PAUT results and the structural analysis of those results to DSCs 11 -15 (Enclosure 5 to the exemption request) . As noted in the exemption request , NSPM determined that there is a reasonable expectation that LOF defects seen in DSC 16 are representative of the potential flaws in the other ITCP closure welds. These conclusions were supported by SIA evaluations as more fully described in the response to RAI M-4 , which included the potential benefits of any learning curve . The following additional information regarding the ITCP welding is provided to support these conclusions.

L-MT-18-013                                                                                    NSPM During the review of the available video records , SIA noted several observations regarding susceptibility for LOF defects located at the DSC shell interfaces being present in both the ITCP passes (root and cap passes) . The root is established using an open root welding technique and the welding torch is positioned on the lid side of the open root joint such that the root is bridged with molten material that washes onto the canister shell wall. This is a common practice for open root geometries to control the weld puddle and avoid dropping molten metal through the gap between the two pieces being joined and blowing out the root. If too much of the molten puddle is directed toward the lid side , then insufficient washing onto the sidewall occurs and LOF defects can occur along the shell wall . Review of the VIDs that captured the root passes of the ITCP for DSCs 13 and 16 (the only ITCP VID information available) observed a potential for LOF at locations around the circumference where the welding arc position did not remain centered on the weld groove. The fixed radial position of the weld head coupled with out-of-roundness of the shell wall caused the welding arc to drift away from the shell wall. This behavior is due to a lack of concentricity between the can ister shell and the radial position of the weld head as it travels around the circumference . As the shell wall moved further away from the welding arc, the molten weld puddle does not properly wash onto the shell wall , and LOF is favored and the welding arc must be repositioned . This behavior is consistent with the observed intermittent LOF indications that were seen along the shell wall associated with the root pass in DSC 16 PAUT inspection results .
The second bead or cap pass was deposited with the welding arc positioned closer to the shell wall as an expected good welding practice with the intention of facilitating good sidewall tie-in and to minimize any potential for LOF defects . The deposit was seen to build preferentially along the shell wall and tapers uniformly downward across the top surface of the root pass as it flows over the edge of the ITCP . The second pass will remelt a small amount of the top of the root bead and recast that material with the second bead . The second pass deposit on the shell side is clearly above the locations where the LOF was suspected . Consistent with the intended purpose of repositioning the welding arc, the results of the PAUT inspection on DSC 16 identified sidewall LOF defects located in the lower portion of the weld commensurate with the root pass tie-in to the sidewall. Further, all DSCs were welded using the same processes ,
procedures, equipment and welders . Shop floor video reviews confirmed similar practices were applied to all canisters . Thus , it is reasonable to expect that the welding arc positioning target would be similar for all canister ITCP welds .
The potential for alignment and stack-up of any LOF defects is further reduced by the remelting which will occur when the second pass remelts a small amount of the top of the root bead and recasts that material with the second bead.
From the SIA review of the shop floor videos , it was observed that DSCs 11 -15 experienced a greater amount of rework during the welding process than was observed for DSC 16 for both the ITCP and OTCP . These details are tabulated in Enclosure 3 to the exemption request. The performance of rework is an indication that the weld ing operators were alert to identifying unfavorable conditions as they developed during welding so that they could be corrected in -process . Therefore , it is reasonable to conclude that the probability for flaws in the closure welds of DSCs 11 -15 should be no greater, and perhaps lower than DSC 16 due to observed in -process of the repairs to correct undesirable features .

L-MT-18-013                                                                                  NSPM There were no observations suggesting that the second bead (cap pass) would produce additional sidewall flaws that might stack-up along the shell wall. To the contrary, significant and effective sidewall tie-in was observed at the shell wall for the second bead in both DSCs 13 and 16 ITCP closure welds . This effective tie -in was due to the closer proximity of the welding arc during the second pass.
NSPM determined that there is a reasonable expectation that flaws would not stack up along the canister shell wall in successive weld layers. This determination is based on the consistency in welders and processes, and associated shift in welding torch position towards the shell wall for its intended purpose of improved side-wall tie-in. The improved side-wall tie-in from the second layer will minimize potential for any possible flaw stack up along the canister shell wall. Beyond this conclusion, NSPM provided additional analyses to evaluate flaws maximized to identify the maximum flaw size that can be tolerated at the design thickness of the welds while still meeting the acceptable design limits .
PAUT examination on DSC 16 identified an actual weld thickness of 0.25" - 0.40" and an actual maximum flaw height of 0.11 " in the ITCP weld . This maximum flaw was extended to account for flaw uncertainties in DSCs 11 -15 up to 0.14". The analyses determined that a connected ligament of 0.05" (e.g., 0.14" flaw in a 0.19" thick weld, 0.20" flaw in a 0.25" thick weld) is sufficient to meet the design limits. Thus, the flaws modeled in Enclosures 4-8 to the exemption request were based on the PAUT results for DSC 16 and expanded to account for flaw uncertainties. Additionally, margin is demonstrated in the fact that the flaws identified via PAUT in DSC 16 were all intermittent in nature whereas the conservatively modeled flaws are full circumferential. Further margin is identified in Enclosures 7 and 8 to the exemption request which account for as-loaded temperature and pressure conditions and site-specific side-drop accident conditions.

However, the ITCP lid groove (weld prep) is 0.25" minimum , and it was confirmed that the weld is also 0.25."  (Exemption Request for Nonconforming Dry Shielded Canister Dye Penetrant Examinations) page 29 of 75 states:

This increased weld size is considered equally applicably to DSCs 11-15 based on the joint configuration and same weld ing process application .
Subsequently, Enclosure 1 page 32 of 75 references the analysis in Enclosure 6 . However, in the discussion of the results contained in Enclosure 6, page 33 of 75 of Enclosure 1 states:
The maximum modeled weld flaws for OTCP to DSC shell weld are 0.43 inch and 0.42 inch in height, which represents about 85% through -wall of the 0.5-inch minimum weld throat. The maximum modeled full-circumferential weld flaws for the ITCP to DSC shell weld are 0.16
* cos(45°) = 0.11 inch and 0.14 inch in height, which represents respectively 58% and 74% through-wall of the 0.19-inch minimum weld throat as shown in Figure 7 (note that in Figure 7, weld heights are labeled as weld lengths).
These statements appear to be provide contradictory information and it is not clear whether the ITCP weld is modeled as the minimum design thickness or as the minimum measured thickness from the PAUT results for DSC 16.
This information is needed to complete the review in accordance with 10 CFR 72 .122(b).
NSPM Response The calculation provided as Enclosure 4 to the exemption request evaluated the critical flaw size based on the maximum radial stresses in the welds due to design loads. This analysis modeled a 0.25" weld. The calculation performed in Enclosure 5 to the exemption request evaluated DSC 16 flaw conditions . These analyses modeled the weld groove as 0.25";
however, the weld was modeled using the weld design thickness of 3/16". The detailed dimensions of the model are shown in Figure 4 of Enclosure 5 to the exemption request.
Conservatively, 0.09" and 0.11 " full circumferential flaws were modeled. Enclosures 6, 7, and 8 to the exemption request used the model developed in Enclosure 5 and , therefore , used an ITCP weld thickness of 3/16".

The intent of the word "iteration" was not the internal iterations AN SYS uses to obtain convergence in a non-linear analysis. Rather, the use of the word "iteration" was meant to illustrate the repetition of the analyses that were performed to obtain the largest flaw that can exist in OSCs 11-15 while ensuring maximum plastic strain remains below the ASME code acceptance limit. Section 4.1 of the calculation provided in Enclosure 6 to the exemption 1
: 11. The model from the calculation provided in Enclosure 5 to the exemption request was also used in the calculation provided in Enclosure 6 to the exemption request.1 Therefore , model details like element types, mesh distribution , material properties , and loads were not repeated in Enclosure

RAI ST-2 Regarding Exemption Request Enclosure 1 , revise the description of using stress in lieu of strain margin(s) of safety as a basis for demonstrating structural performance of DSCs 11-15 using the limit load and elastic-plastic analysis methodology. Page 2 of the enclosure noted that reasonable assurance of weld integrity is demonstrated by adequate stress margin in welds to accommodate flaws. The use of the word , " stress" does not reflect , in context , that only " strain" acceptance criteria in terms of ductility demands were considered in the closure weld evaluation. Similar descriptions i n this and other enclosures may also need to be revised , as appropriate. This information is needed to complete the review in accordance with 10 CFR 72.236(1).

I, Jeff Isakson, depose and say that 1 am a Vice President of TN Americas LLC, duly a uthori zed to execute this affidavit, and have reviewed or caused to have reviewed the information that is identified as proprietary and referenced in the paragraph immediately below. I am submi tting this affidavit in conformance with the provisions of 10 CFR 2.390 of the Commission's regulations for withholding this information.
The information for which proprietary treatment is sought meets the provisions of paragraph (a) (4) of Section 2.390 of the Commi ssion's regulations and is listed below:
* Computer files associated with calculations 11042-0207 Rev. 1, 11042-0208 Rev. 0, and 11042-0209 Rev. 0 I have personal knowledge of the criteria and procedures utilized by TN Americas LLC in designating information as a trade secret, privileged or as confidential commercial or financial information.
Pursuant to the provisions of paragraph (b) (4) of Section 2.390 of the Commission's regulations, the fol lowing is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure, included in the above referenced document, should be withheld .
: 1)  The information sought to be withheld from public disclosure involves com puter files related to calculations associated with the structural analysis of 6IBTH Dry Shielded Can ister (DSC) in the Standardized NUHOMS System, which are owned and have been held in confidence by TN Americas LLC.
: 2)  The information is of a type customarily held in confidence by TN Americas LLC, and not customarily disclosed to the public. TN Americas LLC has a rational basis for determining the types of information customarily held in confidence by it.
: 3)  Public disclosure of the information is likely to cause substantial harm to the competitive position of TN Americas LLC, because the information is related to the design and analys is of the dry spent fuel storage system, the application of which provides a competitive economic advantage. The availability of such information to competitors would enable them to modify their product to better compete with TN Americas LLC, take marketing or other actions to improve their product's position, or impair the position of TN Americas LLC ' s product, and avoid the development of similar data and analyses in support of their processes, methods, or apparatus.
Further the deponent sayeth not.

Pursuant to the NSPM corrective action program and the Confirmatory Order, DSC 16 was restored to compliance with the regulations by an exemption granted in June 2016 (Reference 4). Currently, the subject five DSCs are loaded into Horizontal Storage Modules (HSMs), as reported in References 5 and 6. The enclosed exemption request is structured as discussed in NSPM's most recent project plan update (Reference 7).             strain In summary, the exemption request has determined that the integr" of the 1eld closure welds for DSCs 11-15 can be reasonably assured even though the Te nical Spec 1cation required dye penetrant examinations were nonconforming. The fuel cl ding integrity, eld design, materials, welding process, tests performed, adequate stress margin in the we          to accommodate maximized representative flaws, and demonstration of additional stress margins to address any remaining uncertainties demonstrates the closure weld integrity of DSCs 11-15 is sufficient to ensure that the affected closure welds will continue to perform their design basis functions over the service lifetime of these canisters. In addition, the exemption request demonstrates that the consequences of non-mechanistic weld failures are very low and that the overall risk to the public is also very low. Enclosure 1 provides the exemption request including a description of the basis and technical justification for granting an exemption . The exemption request provides the basis and technical justification to permit continued storage of DSCs 11-15 in their respective HSMs. provides Structural Integrity Associates, Inc.

general area video, welding records, and DSC 16 was performed and determined that the indications found on DSC 16 are representative of those that might be found on DSCs 11-15. Additionally, it was determined that the same bounding analyses performed for DSC 16 should provide similar conservative results for the closure welds on DSCs 11-15.

: 2. Low Dose Consequences for a DSC in Storage : Notwithstanding the weld integrity demonstrated for DSCs 11-15, a reasonable assurance of safety is further supported by a radiological dose analysis. The dose analysis concludes that a non-mechanistic failure of the weld and a postulated release would result in no danger to the public as the dose consequences would be far below the regulatory limit of 5 rem Total Effective Dose Equivalent (TEDE) (Note: unless otherwise specified , all dose quantities identified in this Enclosure are TEDE).

: b. Methodology for Assessing DSC 11-15 Closure Weld Structural Functions Previous analyses that demonstrated stress margins for the DSC 16 closure welds were provided to the NRC in Reference 6.7, and again in Enclosures 2, 4 and 5 to this letter. These evaluations included (1) structural analysis using an analysis-based stress allowance reduction factor and theoretically-bounding full-circumferential flaws, and (2) a structural analysis assuming flaw distributions conservatively derived from the DSC 16 PAUT examination .
To further evaluate the structural integrity of DSCs 11-15, evaluations were performed to determine if it was reasonable to expect that the types and extent of flaw distributions found in DSC 16 could be used to represent the comparable closure welds of DSCs 11-15 (Enclosure 3) and additional analysis was performed using design basis loads with flaws located based on DSC 16 PAUT and maximized such that the weld flaws reached close to acceptable design limits (Enclosure 6) .
Following these evaluations, additional analysis was performed using site-specific heat load and side drop conditions to demonstrate additional margin exists and is available to account for any remaining uncertainty related to the welds (Enclosures 7 and 8) . A description of each of these evaluations follows :
: i. DSC 16 Closure Weld Flaw Evaluation
: a. Analysis-Based Structural Analysis with Theoretical Flaws For the OTCP, the original design basis calculations determined critical flaw sizes. Per ISG-15, the stress reduction factor of partial penetration welds with PT examination is 0.80. Since these welds are noncompliant with the PT requirements , the weld reduction factor is reduced beyond 0.80 based on a set of theoretical flaw distributions that might conceivably have gone undetected during DSC closure weld examinations. Thus , an analysis-based stress allowable reduction factor of 0.7 was calculated . The analysis is included in its entirety in Enclosure 2. Since the original design basis critical flaw calculations already uses a reduction factor of 0.7 , the original analysis remains applicable. These design basis analyses determined for a 360&deg; circumferential flaw, an allowable flaw depth of 0.19 inch and 0.29 inch could exist for surface connected and sub-surface flaws respectively. The flaw sizes determined by these calculations bound any of the indications found on DSC 16 by PAUT.
For the ITCP weld , the calculation provided in Enclosure 4 documents the critical flaw size based on the maximum radial stresses in the welds due to Page 28 of 75


===9.4 Welding===
L-MT-17-053                                                                                    NSPM design loads. The analysis calculates the critical flaw size for a weld size of 0.25 inch per the PAUT results for DSC 16 (which indicated a distance between the root and crown at the canister wall from 0.25 to 0.40 inches) in lieu of the design thickness of 3/16 inch. This increased weld size is considered equally applicable to DSCs 11-15 based on the joint configuration and same welding process application . The calculation assumes both a buried (sub-surface) and a surface flaw. A 360&deg; circumferential flaw was modeled and the critical flaw depth was calculated using ASME Section XI criteria. The critical flaw depth determined , 0.15 inches , is larger than the half of the weld which would exceed the typical weld layer. The original design basis calculation already considered a 0.7 stress reduction factor; therefore ,

no further analyses were performed to show that all component stresses remain below the stress allowable limits .

The flaw sizes determined by these calculations bound any of the indications found on DSC 16 by PAUT. Therefore, these calculations demonstrate that sufficient margin is included in the welds and indicates a reasonable expectation of satisfactory performance of each DSC for the design service lifetime of the DSC .

* ation by applying bounding flaw heights and modeling the intermittent fla      as full circumferential. This structural analysis is fully described in              and concludes that DSC 16 will continue to perform its function due to the adequate margins for the accident pressure and drop loads with the presence of the ITCP and OTCP weld flaw indications documented in the PAUT exam.

ii. Applicability of DSC 16 PAUT to DSCs 11-15 As part of the original extent of condition review , weld head videos were reviewed by SIA in 2014. This review determined that good welding practices were used . However, the video also shows infrequent indications of areas where the potential for small weld flaws could exist. Both inner and outer cover plate closure welds were recorded in some cases , but the video coverage was incomplete for all weld beads. Specifically, the video review covered the ITCP root and cover weld layers; the OTCP tack, root, intermediate and cover weld layers for DSCs 13 and 16; and the OTCP tack, root, intermediate and cover weld layers for DSCs 12, 14 and 15. No weld head video was available for DSC 11. The DSC 16 outer closure weld was concluded to be the most vulnerable to potential defects , because a greater frequency of irregular surface conditions was generated during welding.

iii. Structural Analyses of DSCs 11-15 for Maximum Weld Flaw and Stress Margin Evaluation
: a. Maximized Representative Flaw Evaluation Notwithstanding the conclusions reached by SIA that the bounding flaws used to model the DSC 16 PAUT results would be reasonable to assume for all canisters (DSCs 11-15), NSPM contracted with AREVA to evaluate DSCs 11 -15 closure welds per ASM E Section 111 criteria. The analysis used design basis loads with flaws located based on DSC 16 PAUT results and maximized such that the weld flaws reach close to acceptable design limits.
The purpose of this analysis was to address uncertainties related to the potential flaws that may be present in DSCs 11 -15 by demonstrating the maximum flaws that could be shown to still meet the code limits. The analysis is provided in its entirety in Enclosure 6.
All of the applicable design bases loading conditions are considered in accordance with the requirements of ASME Section Ill Subsection NB.
Similar to previous analysis, the uncertainties in the PAUT examination were accounted for by using a 0.8 reduction factor on the limit load and elastic plastic analyses.
The DSC design used in the calculation was typical of MNGP DSCs 11-16, and the modeled baseline flaws were representative of those indications Page 32 of 75

It should be noted that with the as-loaded temperature and pressure conditions, and site specific side drop loads the margin of safety is higher than the margin of safety in similar analyses for DSC 16 (3.83 vs. 3.60).
Additionally, the analysis used to determine the bounding DSC shell temperature and internal pressure during storage operations based on the as-loaded configuration of DSCs 11-15 is included as Enclosure 9.
3.7    Conclusion Based on the technical assessment presented previously, the proposed activity does not adversely affect the criticality safety, shielding/radiological safety, heat removal, confinement integrity or structural support functions of DSCs 11-15 as described in the UFSAR. In summary, the requested exemption results in continued safe oper"'ra      "=t=io~n~o

The integrity of the field closure welds for DSCs 11-15 can be assured with confidenc even though the TS-required PT examinations were nonconforming. The fuel cladd" g integrity, weld design , materials , welding process, tests performed, adequate stress margins in the welds to accommodate the maximized representative flaws, and demonstration of additional stress margins to address any remaining uncertainties demonstrates the closure weld integrity of DSCs 11-15 is sufficient to ensure that the affected closure welds will continue to perform their design basis functions over the service lifetime of these canisters.
Application of the alternatives described in Section 4.3 would increase the radiological dose to workers , generate additional radiological waste, potentially create foreign material concerns and increase other operational risks to the station without a commensurate increase in safety as compared to receipt of the exemption request.
4.0    Basis for Approval The proposed exemption is limited in scope in that it only relates to compliance with the inspection of certain field closure welds. The proposed exemption involves a change in compliance , but no physical change to the canister design , and no change to the canister materials or the loading operation. In this regard , the proposed activity cannot affect the frequency of any accident caused by the loading process (e.g., dropped TC or jammed DSC).
It has no bearing on the frequency of natural events (flood , earthquake, tornado) that are natural phenomena. Therefore, the proposed activity does not result in an increase in the frequency of any previously evaluated accident. Furthermore, since the exemption does not affect the canister design and procedures this ensures that no new type of malfunction would be created.
The Technical Assessment herein provides the basis for the conclusion that a reasonable assurance of safety exists for the service lifetime of DSCs 11-15. Even though regulations Page 35 of 75 L_

: c. Material and Welding Process: The shell, lid, and weld filler quality requirements were met. Austenitic stainless steels do not have a nil ductility transition temperature and thus the weld can sustain "large" flaws without a concern for flaw growth. Weld process qualification, welder qualification, and automated welding processes designed for the specific application all ensure a quality weld.

Low Dose Consequences for a DSC in Storage: Notwithstanding the weld integrity that is demonstrated for DSCs 11-15, a reasonable assurance of safety is further supported by a radiological dose analysis which concludes that a non-mechanistic fa ilure of the weld and a postulated release would result in dose consequences that would be far below the regulatory limit (5 rem).

: 7) NSPM letter to NRC , "Project Plan Progress Toward Restoring 10 CFR 72 Compliance to Dry Shielded Canisters Designated 11 through 16", dated June 6 , 2017 Pursuant to 10 CFR 72.7 , " Specific Exemptions
" , the Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, requests an exemption from the requirements of 10 CFR 72.212(a)(2), 10 CFR 72.212(b)(3), 10 CFR 72.212(b)(5)(i), 10 CFR 72.212(b)(11), and 10 CFR 72.214 for five NUHOMS Dry Shielded Canisters (DSCs) designated DSCs 11-15 due to nonconforming dye penetrant (PT) examinations performed during the loading campa i gn that started in September 2013. These nonconforming PT examinations are the subject of a Confirmatory Order (Reference 1 ). Please note that an earlier submittal (Reference
: 2) was made to request an exemption for all s i x canisters (designated DSCs 11-16) that were originally found to be nonconforming.
However, that request was withdrawn (Reference
: 3) in 2014. Pursuant to the NSPM corrective action program and the Confirmatory Order, DSC 16 was restored to compliance with the regulations by an exemption granted in June 2016 (Reference 4). Currently , the subject five DSCs are loaded into Horizontal Storage Modules (HSMs), as reported in References 5 and 6. The enclosed exemption request is structured as discussed in NSPM's most recent project plan update (Reference 7). strain ,....._ ______ __, In summary , the exemption request has determined that the integr" of the 1eld closure welds for DSCs 11-1 5 can be reasonably assured even though the Te nical Spec 1cation required dye penetrant examinations were nonconforming.
The fuel cl ding integrity, eld design, materials, welding process, tests performed, adequate stress margin in the we to accommodate maximized representative flaws, and demonstration of additional stress margins to address any remaining uncertainties demonstrates the closure weld integrity of DSCs 11-15 is sufficient to ensure that the affected closure welds will continue to perform their design basis functions over the service lifetime of these canisters.
In addition, the exemption request demonstrates that the consequences of non-mechanistic weld failures are very low and that the overall risk to the public is also very low. Enclosure 1 provides the exemption request including a description of the basis and technical just i fication for granting an exemption. The exemption request provides the basis and technical justification to permit continued storage of DSCs 11-15 in their respective HSMs. Enclosure 2 provides Structural Integrity Associates, Inc. (SIA) Report 1301415.301 , " Development of an Analys i s Based Stress Allowable Reduction Factor (SARF) -Dry Shielded Canister (DSC) Top Closure Weldments", which provides an analysis-based Stress Allowable Reduction Factor, which supports the values used in the analysis of record for the NU HOMS 61 BTH model canister , the canister design used at the Monticello Nuclear Generating Plant.
Document Control Desk Page 3 Enclosure 3 provides SIA Report 700388.401 , "Evaluation of the Welds on DSCs 11-15", which evaluates the available weld head video, general area video, documentation, and DSC 16 Phased Array Ultrasonic Testing (PAUT) results determining that the types of flaws and extent of flaw distributions found in DSC 16 are considered representative of the comparable closure welds of DSCs 11-15. Enclosure 4 provides AREVA Calculation 11042-0204, "Allowable Flaw Size Evaluation in the Inner Top Cover Plate Closure Weld for DSC #16" , which calculates a maximum allowable flaw size in the Inner Top Cover Plate (ITCP) weld for DSC 16 assuming a weld depth of 0.25 inches. Enclosure 5 provides AREVA Calculation 11042-0205, "618TH ITCP and [Outer Top Cover Plate] OTCP Closure Weld Flaw Evaluation", which evaluates the DSC 16 closure weld flaw indications discovered by PAUT examination.
This calculation uses the limit load analysis methodology of the American Society of Mechanical Engineers (ASME) Operation and Maintenance Code, Section Ill. Additionally, elastic-plastic analyses were performed to document the actual predicted strains in the welds and to demonstrate adequate margin against plastic collapse.
Enclosure 6 provides AREVA Calculation 11042-0207, "NU HOMS 618TH Type 1 DSC ITCP and OTCP Maximum Weld Flaw Evaluation", which evaluates the DSCs 11-15 closure welds per ASME Section Ill criteria using design bases loads with flaws located based on DSC 16 PAUT results and maximi d flaws are close to acceptable design limits. strain Enclosure 7 pr

Enclosure 8 provides ARE Calculation 11042-0209, "Site Specific NU HOMS 618TH Type 1 DSC ITCP and OTC Margin Evaluation for Maximum Weld Flaw with Side Drop Loads", which evaluates the stress margins for DSCs 11-15 with the maximized flaws in the ITCP and OTCP closure welds based on the as-loaded temperature and pressure conditions and site-specific side-drop loads. Enclosure 9 provides AREVA Calculation 11042-0400, "Site-Specific Thermal Evaluation of 618TH Type 1 DSCs Stored in HSM-H at Monticello Nuclear Generating Plant", which evaluates the bounding DSC shell temperature and internal pressure during storage based on as-loaded conditions.
This calculation provides an input to the calculations submitted as Enclosures 7 and 8, which are used to establish the actual safety margins based on the as-loaded conditions of DSCs 11-15. This calculation provided in Enclosure 9 contains proprietary information and is sought to be withheld from public disclosure in accordance with 10 CFR 2.390. As the entirety of the calculation is considered to be the intellectual property of AREVA, a redacted version of the calculation has not been included.
The affidavit for the enclosure is provided in Enclosure

L-MT 053 Enclosure 1 NSPM is not a credible phenomenon. Service-induced flaws under normal and off-normal conditions of storage are not credible.
: c. Material and Welding Process: Shell, lid, and weld filler quality requirements were met. Austenitic stainless steels do not have a nil ductility trans i tion temperature and thus the weld can sustain " large" flaws without a concern for flaw growth. Weld process qualification, welder qualification , and the automated welding processes designed for the specific application all ensure a quality weld. d. Tests Performed: In-process visual inspections of welds performed by the welders , Quality Control (QC) visual examination (VT) inspections of fit-ups and welds and the vacuum hold , helium pressure and helium leak test all ensured confinement and quality of the welds. k?7 ~..._s_tr_a_in
____ e. Adequate Stre et M argin in Welds to Accommodate Flaws: St r ess margins were demonstrated by structural analysis using an analysis based stress allowance reduction factor, theoretically bounding full circumferential flaws, and a structural analysis assuming flaw distributions conservatively derived from Phased Array Ultrasonic Testing (PAUT) examination of DSC 16. A review of the weld head video , general area video, welding records, and DSC 16 was performed and determined that the indications found on DSC 16 are representative of those that might be found on DSCs 11-15. Additionally , it was determined that the same bounding analyses performed for DSC 16 should provide similar conservative results for the closure welds on DSCs 11-15. Regardless , further analyses have been performed to maximize the flaws located based on DSC 16 PAUT to demonstrate substantial margin to account for potential flaw uncertainties. These analyses are provided in Enclosures 2 through e,. < !6 I f. Additional Stress Margins in Welds: DSCs 11-15 heat loads and site-specific side drop conditions were applied to demonstrate additional margin exists and is ava i lable to account for any remaining flaw uncertainty that may exist. These analyses are provided in Enclosures e throu~h 9. ~7 I 2. Low Dose Consequences for a DSC in Storage: Notwithstanding the weld integrity demonstrated for DSCs 11-15 , a reasonable assurance of safety is further supported by a radiological dose analysis.
The dose analysis concludes that a non-mechanistic failure of the weld and a postulated release would result in no danger to the public as the dose consequences would be far below the regulatory limit of 5 rem Total Effective Dose Equivalent (TEDE) (Note: unless otherwise specified , all dose quantities identified in this Enclosu r e are TEDE). The dose analysis is provided in Enclosure
: 10. 3. Low Risk to the Public: Notwithstanding the weld integrity demonstrated for DSCs 11-15, a reasonable assurance of safety is further supported by a probabilistic risk assessment (PRA). This assessment concludes the risk of a potential Latent Cancer Fatality (LCF) for all five DSCs with noncompliant PT exams over a 20 year storage period is extremely unlikely (1.39E-12 LCF) and the risk associated with the Page 2 of 75 L-MT-17-053 Enclosure 1 NSPM examination (i.e., PT) vs. volumetric examination technique (i.e., PAUT), and the potential for subsurface flaws to exist when only surface examinations are performed. Additionally, the maximum weld deposit depth for intermediate layers is kept smaller than the critical flaw depth in accordance with ISG-15. b. Methodology for Assessing DSC 11-15 Closure Weld Structural Functions Previous analyses that demonstrated stress margins for the DSC 16 closure welds were provided to the NRC in Reference 6.7 , and again in Enclosures 2 , 4 and 5 to this letter. These evaluations i ncluded (1) structural analysis using an analysis-based stress allowance reduction factor and theoretically-bounding full-circumferential flaws, and (2) a structural analysis assum i ng flaw distributions conservatively derived from the DSC 16 PAUT examination. To further evaluate the structural integrity of DSCs 11-15, evaluations were performed to determine if it was reasonable to expect that the types and extent of flaw distributions found in DSC 16 could be used to represent the comparable closure welds of DSCs 11-15 (Enclosure
: 3) and add i tional analysis was performed using design basis loads with flaws located based on DSC 16 PAUT and maximized such that the weld flaws reached close to acceptable design limits (Enclosure 6). Following these evaluations , additional analysis was performed using site-specific heat load and side drop conditions to demonstrate additional margin exists and is ava i lable to account for any remaining uncertainty related to the welds (Enclosures 7 and 8). A description of each of these evaluations follows: i. DSC 16 Closure Weld Flaw Evaluation
: a. Analysis-Based Structural Analysis with Theoretical Flaws For the OTCP , the original design basis calculations dete r mined critical flaw sizes. Per ISG-15 , the stress reduction factor of partial penetration welds with PT examination is 0.80. Since these welds are noncompliant with the PT requirements , the weld reduction factor is reduced beyond 0.80 based on a set of theoretical flaw distributions that might conceivably have gone undetected during DSC closure weld examinations.
Thus , an analys i s-based stress allowable reduction factor of 0.7 was calculated. The analysis is included in its entirety in Enclosure
: 2. Since the original design basis critical flaw calculations already uses a reduction factor of 0.7 , the original analysis remains applicable.
These design basis analyses determined for a 360&deg; circumferential flaw , an allowable flaw depth of 0.19 inch and 0.29 inch could exist for surface connected and sub-surface flaws respectively.
The flaw sizes determined by these calculations bound any of the indications found on DSC 16 by PAUT. For the ITCP weld , the calculation provided in Enclosure 4 documents the c r itical flaw size based on the maximum radial stresses in the welds due to Page 28 of 75 L-MT-17-053 Enclosure 1 NSPM design loads. The analysis calculates the critical flaw size for a weld size of 0.25 inch per the PAUT results for DSC 16 (which indicated a distance between the root and crown at the canister wall from 0.25 to 0.40 inches) in lieu of the design thickness of 3/16 inch. This increased weld size is considered equally applicable to DSCs 11-15 based on the joint configuration and same welding process application. The calculation assumes both a buried (sub-surface) and a surface flaw. A 360&deg; circumferential flaw was modeled and the critical flaw depth was calculated using ASME Section XI criteria.
The critical flaw depth determined , 0.15 inches , is larger than the half of the weld which would exceed the typical weld layer. The original design basis calculation already considered a 0.7 stress reduction factor; therefore , no further analyses were performed to show that all component stresses remain below the stress allowable limits. The flaw sizes determined by these calculations bound any of the indications found on DSC 16 by PAUT. Therefore, these calculations demonstrate that sufficient margin is included in the we l ds and indicates a reasonable expectation of satisfactory performance of each DSC for the design service l i fetime of the DSC. b. Structural Analysis Using PAUT Flaw Distribution:
Enclosure 5 A structural analysis was performed assuming flaw stributions conservatively derived from DSC 16 PAUT exa
* ation by applying bounding flaw heights and modeling the intermittent fla as full circumferential.
This structural analysis is fully described in and concludes that DSC 16 will continue to perform its function due to the adequate margins for the accident pressure and drop loads with the presence of the ITCP and OTCP weld flaw indications documented in the PAUT exam. ii. Applicability of DSC 16 PAUT to DSCs 11-15 As part of the original extent of condition review , weld head videos were reviewed by SIA in 2014. This review determined that good welding practices were used. However , the video also shows infrequent indications of areas where the potential for small weld flaws could exist. Both inner and outer cover plate closure welds were recorded in some cases , but the video coverage was incomplete for all weld beads. Specifically, the video review covered the ITCP root and cover weld layers; the OTCP tack, root , intermediate and cover weld layers for DSCs 13 and 16; and the OTCP tack , root, intermediate and cover weld layers for DSCs 12 , 14 and 15. No weld head video was available for DSC 11. The DSC 16 outer closure weld was concluded to be the most vulnerable to potential defects , because a greater frequency of irregular surface conditions was generated during welding.

: a. Maximized Representative Flaw Evaluation Notwithstanding the conclusions reached by SIA that the bounding flaws used to model the DSC 16 PAUT results would be reasonable to assume for all canisters (DSCs 11-15), NSPM contracted with AREVA to evaluate DSCs 11-15 closure welds per ASM E Section 111 criter i a. The analysis used design basis loads with flaws located based on DSC 16 PAUT results and maximized such that the weld flaws reach close to acceptable design limits. The purpose of this analysis was to address uncertainties related to the potential flaws that may be present in DSCs 11-15 by demonstrating the maximum flaws that could be shown to still meet the code limits. The analysis is provided in its entirety in Enclosure
: 6. All of the applicable design bases loading conditions are considered in accordance with the requirements of ASME Section Ill Subsection NB. Similar to previous analysis , the uncertainties in the PAUT exam i nation were accounted for by using a 0.8 reduction factor on the l i mit load and elastic plastic analyses. The DSC design used in the calculation was typical of MNGP DSCs 11-16 , and the modeled baseline flaws were representative of those indications Page 32 of 75 L-MT-17-053 Enclosure 1 NSPM one weld bead. These flaws were located based on DSC 16 PAUT results and are considered representative locations for DSCs 11-15. < !Strain I b. Additional Stress Margins in Welds Notwithstanding the conclusions re che by SIA that the bounding flaws used to model the DSC 16 PAUT results would e reasonable to assume for DSCs 11-15, and the analysis by A EVA sh wing large flaws that could still be shown to meet the code limits , ditional a lyses were performed by AREVA to demonstrate additional stress margin xists using site-specific heat loads and side drop conditions.
The purpose of th e analyses was to address any remaining uncertainties related to pote
* I flaws that may be present in DSCs 11-15 by demonstrating additional stress margins. These analyses are provided in their entirety in Enclosures 7 and 8. Enclosure 7 evaluates the margins for DSCs 11-15 with the maximum flaws in the ITCP and OTCP closure welds based on the as-loaded temperature and pressure conditions.
Load Limit Analysis:
The lower bound collapse pressure for Service Level A/B criteria was found to be 98.4 psi which is greater than the limiting pressure of 60 psi. Therefore the Service Level A/B criterion is satisfied.
The lower bound collapse pressure for Service Level D criteria was found to be 144.1 psi which is greater than the limiting pressure of 90.2 psi. The lower bound collapse G-Load for Service Level D side drop criteria was found to be 204 g which is greater than the limiting G-Load of 104 g. Therefore the Service Level D criterion is satisfied. Elastic-Plastic Analyses:
The peak strains predicted by the elastic-plastic analyses for the bounding Service Level D event are shown to remain below the material ductility limits (28%) at the specified loading conditions, and also at one and a half times the specified loads, with a minimum margin of safety of 1.86. Therefore the elastic plastic analyses criteria are satisfied.
Enclosure 8 evaluates margins for the DSCs with the maximum flaws in the ITCP and OTCP closure welds based on the as-loaded temperature and pressure conditions , and the site specific side drop loads (i.e., actual approach slab parameters). Limit Load Analysis:
The lower bound collapse G-Load for Service Level D side drop criteria was found to be 204 g which is greater than the limiting G-Load of 104 g. Therefore the Service Level D criterion is satisfied.
Elastic-Plastic Analysis:
The peak strain values remain below the material ductility limits at the specified loading conditions with a minimum margin of Page 34 of 75 L_ L-MT-17-053 Enclosure 1 NSPM safety of 3.83. Therefore the elastic plastic analyses criteria are satisfied.
It should be noted that with the as-loaded temperature and pressure conditions, and site specific side drop loads the margin of safety is higher than the margin of safety in similar analyses for DSC 16 (3.83 vs. 3.60). Additionally, the analysis used to determine the bounding DSC shell temperature and internal pressure during storage operations based on the as-loaded configuration of DSCs 11-15 is included as Enclosure
: 9. 3.7 Conclusion Based on the technical assessment presented previously, the proposed activity does not adversely affect the criticality safety, shielding/radiological safety , heat removal, confinement integrity or structural support functions of DSCs 11-15 as described in the UFSAR. In summary, the requested exemption results in continued safe ope r"'" ra=t=io~n~o=f~----, the MNGP ISFSI. strain ,__-----.----~
The integrity of the field closure welds for DSCs 11-15 can be assured with confidenc even though the TS-required PT examinations were nonconforming.
The fuel cladd" g integrity, weld design , materials , welding process, tests performed, adequate stress margins in the welds to accommodate the maximized representative flaws, and demonstration of additional stress margins to address any remaining uncerta i nties demonstrates the closure weld integrity of DSCs 11-15 is sufficient to ensure that the affected closure welds will continue to perform their design basis functions over the service lifetime of these canisters.
Application of the alternatives described in Section 4.3 would increase the radiological dose to workers , generate additional radiological waste, potentially create foreign material concerns and i ncrease other operational risks to the station without a commensurate increase in safety as compared to rece i pt of the exemption request. 4.0 Basis for App r oval The proposed exemption is limited in scope in that it only relates to compliance with the inspection of certain field closure welds. The proposed exemption involves a change in compliance , but no physical change to the canister design , and no change to the canister materials or the loading operation.
In this regard , the proposed activity cannot affect the frequency of any accident caused by the loading process (e.g., dropped TC or jammed DSC). It has no bearing on the frequency of natural events (flood , earthquake , tornado) that are natural phenomena.
Therefore, the proposed activity does not result in an increase in the frequency of any previously evaluated accident.
Furthermore, since the exemption does not affect the canister design and procedures this ensures that no new type of malfunct i on would be created. The Technical Assessment herein provides the basis for the conclusion that a reasonable assurance of safety exists for the service lifetime of DSCs 11-15. Even though regulations Page 35 of 75 L-MT 053 Enclosure 1 NSPM c. Material and Welding Process: The shell, lid, and weld filler quality requirements were met.

In accordance with 10 CFR 72 .7, Northern States Power Company, a Minnesota corporation (NSPM) , doing business as Xcel Energy, requested in Reference 1, a permanent exemption from the requirements of 10 CFR 72 .212(a)(2) , 10 CFR 72.212(b)(3) , 10 CFR 72.212(b)(5)(i) ,

10 CFR 72.212(b)(11 ), and 10 CFR 72.214 for five NUHOMS Dry Shielded Canisters (DSCs) ,

designated DSCs 11 -15, due to nonconforming dye penetrant (PT) examinations performed during the loading campaign that started in September 2013 at the Monticello Nuclear Generating Plant (MNGP). In Reference 2, the NRC provided a Request for Additional Information (RAI) regarding NSPM 's application in Reference 1. Enclosu re 1 to this letter provides NSPM 's response to the NRC RAls.

Document Control Desk Page 2 As detailed in Reference 1, NSPM determined that the integrity of the field closure welds for DSCs 11-15 can be reasonably assured. The dry shielded canister system employed by NSPM for MNGP provides multiple layers of defense in depth, for example fuel selection criteria, fuel cladding, approved designs, use of qualified materials, qualified multi-pass welding processes, qualified personnel and helium leak checks to assure weld integrity and confinement. NSPM has extensively analyzed all available evidence of the welds and welding process and identified potential indications, then postulated conservative hypothetical indications to assess uncertainties under design loading conditions to reveal the extensive available margin. Further, NSPM has utilized an independent industry weld expert to ensure a thorough understanding of the welds and welding processes . The enclosed RAI responses provide additional details that address NRC questions related to the exemption request and supporting analyses . These responses further exemplify the NSPM position that reasonable assurance exists that the canister welds are structurally acceptable and can perform all intended functions notwithstanding the nonconforming PT examinations on the closure welds.

Furthermore, NSPM maintains that with DSCs 11-15 loaded in their respective horizontal storage modules , the canisters are in their safest possible configuration. provides Welding Procedure Specification (WPS) SS-8-M-TN, Revision 10.

L-MT-18-013 NSPM RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION EXEMPTION REQUEST FOR NONCONFORMING DYE PENETRANT EXAMINATIONS OF DRY SHIELDED CANISTERS (DSCS) 11 THROUGH 15 On October 18, 2017, Northern States Power Company, a Minnesota corporation (NSPM),

doing business as Xcel Energy, submitted a request for a permanent exemption for the Monticello Nuclear Generating Plant (MNGP) . Specifically, NSPM requested a permanent exemption from the requirements of 10 CFR 72.212(a)(2), 10 CFR 72.212(b)(3),

10 CFR 72.212(b)(5)(i) , 10 CFR 72.212(b)(11 ), and 10 CFR 72.214 for five NU HOMS Dry Shielded Canisters (DSCs) , designated DSCs 11-15, due to nonconforming dye penetrant (PT) examinations performed during the loading campaign that started in September 2013. By letter dated March 6, 2018 , the NRC requested the following additional information. The response to this request for additional information (RAI) is provided below.

Materials RAls RAI M-1 Provide the procedure qualification records for the welding procedure specifications (WPSs) used for the Inner Top Cover Plate (ITCP) and Outer Top Cover Plate (OTCP) welds. In , these are listed as WPS SS-8-M-TN Revision 10 (machine GTAW) and SS-8-A-TN Revision 8 (manual GTAW). of the exemption request states:

Notwithstanding the nonconforming PT examinations, the weld closures of DSCs 11-15 were performed under a 10 CFR 50 Appendix B QA [Quality Assurance] program , such that the canister integrity is otherwise assured.

Accordingly, welding materials were procured to quality requirements, welding processes were developed and qualified for the given configuration , and welders were appropriately qualified to the Code requirements .

The use of a qualified welding procedure is relied on to support the exemption request.

However, observations from the review of the weld head videos appear to be inconsistent with expected observations when using a qualified welding procedure .

This information is needed to determine compliance with 10 CFR 72 .122(a) .

NSPM Response WPSs SS-8-M-TN , Revision 10, and SS-8-A-TN , Revision 8, were used in the closure welding for DSCs 11-16. These documents are provided in Enclosures 2 and 3, respectively.

Procedure qualification record (PQR) PQR-1 , Revision 2, is identified as the supporting PQR for these two WPSs . PQR-1, Revision 2, is provided in Enclosure 4.

Page 1 of 14

L-MT-18-013 NSPM NSPM concludes that the welds were performed under a 10 CFR 50, Appendix B, Quality Assurance program such that the canister integrity is otherwise assured . The welds were performed by qualified welders using qualified welding procedures. Structural Integrity Associates (SIA) , an engineering consulting firm with over 20 years of experience resolving spent fuel storage issues which employs industry experts in the areas of structural analysis and materials engineering among others , reviewed the welding performed via available video records and determined that the welding was performed consistent with the qualified procedures.

Welding procedures were qualified in accordance with Section IX of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. As required by the Code , a test sample was welded and destructively tested to meet specific minimum requirements for procedure qualification . The WPS was prepared subsequently based on specific values of the essential variables used to weld the procedure qualification sample(s) having acceptable mechanical properties. The Code provides allowable ranges of the essential variables that can be used based on the parameters tested. Weld data sheets documented that the qualified and approved welding procedures were followed for all welds .

Machine weld head video files (VIDs) were reviewed by the chief welding engineer at SIA who is a fellow of the American Welding Society, has a doctorate in materials science engineering and 50 years of experience in the application of materials science to the electric utility industry ,

primarily in the nuclear power industry . The VID review examined the welding conditions used and determined , based on the chief welding engineer's extensive nuclear welding experience ,

that the welding arc length , the wire feed entry, the arc lengths achieved , and the molten weld puddle and deposit cha racteristics were consistent with expectations for the specified welding parameters .

The eight tack welds and all circumferential closure welds (both for the ITCP and OTCP that were available for review) utilized the WPS SS-8-M-TN, Revision 10, gas tungsten arc welding (GTAW) machine welding procedure. The use of the manual GTAW weld ing procedure was limited to localized repairs and for cleaning up the corners of the keyway welds. Manual welds had no arc video records for review ; therefore , their review relied on viewing from long range shop floor cameras. It was determined that manual welding was used in some instances based on the observed arc shine .

Based on the preceding discussion , NSPM concludes that the observations from the review of the weld head videos are consistent with the use of qualified welding procedures .

RAI M-2 Provide the certified material test reports (CMTRs) for the weld filler material heats used in the closure lid welding for DSCs 11 -15.

These heat numbers are identified as 737880 , 736908 and 527221 in Enclosure 3: Structural Integrity Associates , INC . Report 700388.401 , Revision 1, Evaluation of the Welds on Page 2 of 14

L-MT-18-013 NSPM DSC 11-15, Page 3-23, Table 3-1, Welder ID numbers and filler metal heat numbers used [4, 5, 6, 7, 8, 9].

The use of a certified welding filler materials is relied on to support the exemption request. The CMTRs for these filler metals were not provided in the exemption request.

This information is needed to determine compliance with 10 CFR 72.122(b).

NSPM Response Weld filler material heat numbers 527221, 736908, and 737880 were used in the closure lid welding for DSCs 11-16. The CMTRs for these weld filler material heats are provided in .

RAI M-3 Provide the technical basis and evidence, such as measurements, of the actual thickness of the weld deposits on DSCs 11-15 to support the use of a weld deposit thickness that is greater than the weld design dimension.

The applicant stated that the inner top cover plate weld size (dimension of the weld throat) for DSC 16 was determined to be between 0.25 to 0.4" which is considerably larger than the minimum design thickness of 3/16 inch (i.e., 0.188"). The applicant stated that the increased ITCP weld size was considered applicable to DSCs 11-15. However, no evidence such as actual measurements of the ITCP welds were provided to support this assertion.

This information is needed to determine compliance with 10 CFR 72.122(b).

NSPM Response NSPM determined there is a reasonable expectation that the ITCP welds on DSCs 11 -15 have an actual thickness of 0.25". The technical basis supporting use of a weld deposit thickness greater than the weld design dimension of 3/16" is derived from the following items: the actual phased array ultrasonic testing (PAUT) weld measurements for DSC 16, review of the VIDs for the ITCP welds on DSCs 13 and 16 by the SIA chief welding engineer, the weld design/geometry and component fit-up as well as the physical requirements to accomplish the weld per the qualified welding process using the same GTAW machine, and use of a limited number of welders .

The NRC has previously reviewed and accepted the DSC 16 PAUT data including the understanding of the actual weld measurements by way of granting an exemption for DSC 16 on June 15, 2016 (Agencywide Document Access and Management System (ADAMS)

Accession No. ML16167A035).

SIA's chief welding engineer reviewed the VIDs for the ITCP welds for DSCs 13 and 16. The chief welding engineer also provided an assessment of the physical welding process for this Page 3 of 14

L-MT-18-013 NSPM weld design and geometry. The procedures used for the welding and visual examination (VT) inspections are included as Enclosure 6 and 7, respectively. For the ITCP welds , the weld groove volume is small and the deposition rate nearly fills the groove with the root pass alone .

The chief welding engineer noted that the weld root gap varied slightly around the circumference due to fit-up and unequal weld shrinkage as a result of root tacking (eight equally spaced tacks applied by machine welding) . The small changes in weld groove volume resulting from the root gap variation appeared to cause small fluctuations in the groove fill observed on the plate side of the groove edge. The observations supporting this effect were minor variations from slight underfill to slight overfill at the plate edge during the root bead.

During welding , the tungsten position frequently was adjusted to manage the molten deposit.

The root bead crown appeared to be relatively flat and fused into the shell wall. It was noted that the welding arc was positioned approximately midway across the groove during root bead welding .

The welding arc for the second weld bead was repositioned closer to the shell wall resulting in a deposit profile that is thickest at the shell wall tapering downward to the ITCP surface such that the molten material slightly washes over the edge of the ITCP. Weld pass 2, the cap pass ,

clearly overfilled the groove. The completed weld geometry is a partial penetration groove weld having an unequal leg length fillet cap. The SIA chief welding engineer also noted that the deposition rates for all beads appeared consistent based on a visual assessment of the welding travel speed and molten weld puddle size .

NSPM determined there is a reasonable expectation that the ITCP welds for DSCs 11-15 have an actual thickness of 0.25" because the weld groove height is 0.25", the confirmation from the as-measured data from DSC 16 PAUT, the consistency resulting from the adherence to the qualified weld procedure and techniques, a limited set of qualified welders using the same GTAW machine while implementing a controlled fit-up for the small weld groove volume , and maintenance of a consistent weld deposition rate . These considerations are supported by the PAUT measurements and assessment provided by the SIA chief welding engineer VID review of the DSCs 13 and 16 ITCP welds.

L-MT-18-013 NSPM References 1 and 2 are cited in multiple instances in Enclosure 3 and are used to support the assessment of potential defects in the DSC 11-15 welds . The summary of the weld head videos provided in Enclosure 3 Appendix C is a summary of the assessment and is also incomplete as there is no specific comments associated with the DSC-16 weld . A more detailed assessment of the welding videos and weld data sheets beyond what is summarized in the exemption request Enclosure 3 is necessary [to] assess the analysis provided for DSCs 11 through 15.

This information is needed to complete the review in accordance with 10 CFR 72 .122(b).

NSPM Response The requested documents identified as items 1 and 2 above are provided in Enclosures 8 and 9, respectively. The requested welding data sheets (item 3) , in addition to inspection results, are provided in Enclosure 10.

The requested documents form part of the independent expert review of the welding that was performed by SIA. SIA was selected to perform these reviews based on their extensive knowledge and experience with the welding processes employed. Based on this expert review ,

NSPM determined that there is a reasonable expectation to conclude the closure welds performed on DSCs 11-15 are of sufficient quality to protect the health and safety of the public.

This conclusion is based on the fact that the welding process used is expected to provide adequate quality welds , a video review confirmed that appropriate welding practices were used , the closure welds on DSC 16, as found by the NRC , provide reasonable assurance of adequate protection to the health and safety of the public, and the flaws identified via PAUT of DSC 16 are considered representative of potential flaws in DSCs 11-15. A description of the SIA review is provided below. provides SIA report 1301415.402, Revision 0. This report documents a review of the welding procedures to determine if the welding process associated with the closure welds would produce suitable quality welds . The report concludes that the GTAW welds in DSCs 11-15 can reasonably be expected to be of good quality and free of inj urious defects .

This conclusion is based on the characteristics of the GTAW weld , the controls outlined for the welding program , and the fact that the welds and base metals are austenitic stainless steels. provides SIA report 13014145.403, Revision 2. A summary of this report was included in the exemption request in Appendix C to Enclosure 1. This report documented a review of the weld quality by using the available weld head videos. This report provides a sampling of typical welding practices across the industry. Evidence of good welds being applied is ample and dominates the video. DSC 16 was demonstrated through PAUT and analysis to be acceptable even though SIA concluded, based on the review of available video records, it had the greatest likelihood for defects.

Appendix B to Enclosure 2 of the exemption request provided SIA report 1301415.405, Revision 0. This report performed a qualitative assessment of the likelihood that the welds Page 5 of 14

L-MT-18-013 NSPM might contain unacceptable defects . The report concluded it was reasonable to expect the welds were free from large discontinuities based on many factors including the app lication of a proven and robust welding system designed specifically to support these canister field we lds ,

use of ductile and easily weldable base materials , and the use of so lid wire filler material designed for welding these base materials. The report included a review of literature regarding generation of defects in stainless steel weldments and concluded that the likelihood for large defects was not supported . The report concluded the most likely lack of fusion (LOF) defects would be intermittent in nature and not expected to have a through thickness dimension greater than one weld bead . These conclusions were confirmed by the PAUT performed on DSC 16. to the exemption request provided SIA report 700388.401 , Revision 1. A summary of this report was provided in Appendix C to Enclosure 1 of the exemption request. This report performed an evaluation using all available data including the shop floor videos and the available PAUT results to determine if the types and extent of flaw distributions found in DSC 16 were representative of DSCs 11 -15. This report concluded that, based on the evidence developed by reviewing the videos and the rest of the available evidence , it was reasonable to conclude that the conditions determined for the closure welds in DSC 16 are representative of the welds in DSCs 11 -15. The tabulated details for DSC 16 weld beads have been updated for the ITCP to separate the original start of bead 2 (VID-2) and the restart from the original keyway position after grinding (VID-3) and are provided below as Table 1 to better summarize the observations .

L-MT-18-013 NSPM RAI M-5 Provide an explanation for why the information summarized from the weld head videos (Enclosure 3 Appendix C) and the shop floor videos (Enclosure 3 Appendix D) appear to be inconsistent and in some cases contradictory For example :

1. Appendix C Page C-2 and Appendix D Page D-7 Table 5-8: DSC-16 :
a. ITCP and OTCP welding start and stop times are not in agreement.
2. Appendix C Page C-3 and Appendix D page D-5 Table 5-4: DSC-12:
a. OTCP welding start and stop times are not in agreement.
b. Appendix C Page C-3 identifies grinding in layer #2 that is not identified in Table 5-4.
3. Appendix C Pages C-4 and C-5 and Appendix D Page D-5 Table 5-5: DSC-13 :

a. OTCP welding start and stop times (and dates) are not in agreement.

This information is needed to complete the review in accordance with 10 CFR 72 .122(b).

NSPM Response The weld head video clock was approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 17 minutes beh ind the shop floor video clock. This difference between the clocks account for the majority of the inconsistencies between start and stop times noted in the RAI. For the remainder of the inconsistencies , it should be noted that judgment was required to identify the exact weld start and stop times because it had to take into consideration such factors as camera angles , stripper bead activities , etc. Furthermore , grinding was confirmed to have occurred in all cases where it was Page 7 of 14

L-MT-18-013 NSPM identified during the weld head video review but not the shop floor video review. The initial shop floor video review inadvertently missed the grinding that was performed .

The weld head videos and the shop floor videos were both used for the evaluation performed by SIA. The information sought from each information source is different and were never intended to be tracked against each other. Therefore, the time stamps for each information source were never synchronized nor were they intended to be synchronized . The information derived from the review of the shop floor videos and weld head videos was used to identify the types and extent of activities being conducted for each canister, and to corroborate these activities where possible. The shop floor videos were used in a qualitative sense to infer weld related activities for the canister and were available for all canister welds except for the ITCP on DSC 12; however weld head VIDs were incomplete and portions were unavailable for review (i.e., DSC 11 and certain segments in several of the other canisters) . The principal value was to examine the types and frequencies of weld-related activities to look for similarities or significant differences . In some cases , periodic grinding was apparent and in other cases ,

local weld repairs were observed . However, no significant differences were seen in work activity or frequency. This information was used as supporting information for the evaluations.

RAI M-6 Provide additional information to support the assumed flaw size and location of the potential lack of fusion flaws in the ITCP welds for the "Reasonable Assurance of Weld Integrity" and the "Additional Stress Margins in Welds" analyses.

For the "Reasonable Assurance of Weld Integrity" analysis Enclosure 1, Page 30 of 75 states the following :

LOF [lack of fusion] defects of similar sizes and locations seen in DSC 16 are reasonable assumptions for the other ITCP closure welds . The assumptions made for the ITCP closure weld bounding analysis in DSC 16 are considered reasonable for all ITCP canister closure welds , the conditions of the ITCP welds are judged as similar for all canisters .

Additional statements in this paragraph indicate lack of fusion defects that might form would likely be located on the vertical sidewall because of the weld groove geometry and because there is limited room to tilt the tungsten electrode towards the side wall. The lack of fusion defects in the sidewall of the ITCP weld on DSC 16 were modeled as a defect in the root pass or layer 1 of 2. It is unclear why weld layer 2 would not also contain lack of fusion defects.

Weld head video is limited to DSCs 13 and 16, and additional review of the welding process to qualitatively assess the potential for lack of fusion defects for the remaining DSC ITCP welds is not possible. In addition , the initial DSCs would have little to no benefit from any "learning curve" for the ITCP welds.

In the "Additional Stress Margins in Welds" analysis , the assumed flaw size of 0.14" is used for ITCP weld flaw-2 in Enclosure 6, "NU HOMS 61 BTH Type 1 DSC ITCP and OTCP Maximum Weld Flaw Evaluation ," AREVA Calculation 11042-0207, Revision 0.

Page 8 of 14

L-MT-18-013 NSPM Enclosure 1 However, Enclosure 3 Section 3.1.4.1 (page 3-9 or 142/461 of ML17296A205) states:

The video welding records (VIDs) reviewed for this weld did not show evidence of electrode tilt (working angle) towards the vertical sidewall to facilitate optimum tie-in to the vertical wall of the weld joint[ ... ]. Regardless , the VIDs suggested a nearly vertical tungsten orientation that required the molten weld metal to flow to the side wall with sufficient heat to fuse the bottom of the machined groove to the shell sidewall. The sluggish nature of weld metal flow (lava flow) and the issues encountered with maintaining the proper wire entry location due to the filler wire cast created variability in fusion conditions on the sidewall.

The ITCP weld is 2 passes with a design thickness of 3/16" (0.188"). The maximum flaw size observed at the ITCP weld/DSC shell interface in DSC 16 was 0.09" according to the Phased Array Ultrasonic Testing (PAUT) results . Because ITCP weld video is limited to DSCs 13 and 16, additional review of the welding process to assess the welding practices and qualitatively assess the potential for lack of fusion defects for the remaining DSC ITCP welds is not possible.

Based on the review of the welding video records in Enclosure 3, it appears that the ITCP weld joint would be susceptible to lack of fusion flaws at the ITCP weld to shell interface . Given the limited information provided on the ITCP welds and the combination of the weld joint geometry, unfavorable electrode position and the sluggish nature of the weld metal observed during the welding of DSCs 11-16, it is unclear if the modeled lack of fusion defects in the ITCP weld would be representative of the possibility that lack of fusion defects located at weld to DSC shell interfaces could be present in both of the ITCP weld passes . Because it is not possible to assess through weld head videos whether DSCs 11 , 12, 14, and 15 may have lack of fusion defects in both weld passes that comprise the ITCP weld, it is unclear whether the modeled flaw size of 0.14 inches would account for the potential for the ITCP welds to have aligned lack of fusion defects (i.e. , lack of fusion defects in each of the two weld passes) located at the DSC shell to ITCP weld interface .

Th is information is needed to complete the review in accordance with 10 CFR 72.122(b) .

NSPM Response to the exemption request, Page 29 of 75, describes the applicability of the DSC 16 PAUT results and the structural analysis of those results to DSCs 11 -15 (Enclosure 5 to the exemption request) . As noted in the exemption request , NSPM determined that there is a reasonable expectation that LOF defects seen in DSC 16 are representative of the potential flaws in the other ITCP closure welds. These conclusions were supported by SIA evaluations as more fully described in the response to RAI M-4 , which included the potential benefits of any learning curve . The following additional information regarding the ITCP welding is provided to support these conclusions.

Page 9 of 14

L-MT-18-013 NSPM During the review of the available video records , SIA noted several observations regarding susceptibility for LOF defects located at the DSC shell interfaces being present in both the ITCP passes (root and cap passes) . The root is established using an open root welding technique and the welding torch is positioned on the lid side of the open root joint such that the root is bridged with molten material that washes onto the canister shell wall. This is a common practice for open root geometries to control the weld puddle and avoid dropping molten metal through the gap between the two pieces being joined and blowing out the root. If too much of the molten puddle is directed toward the lid side , then insufficient washing onto the sidewall occurs and LOF defects can occur along the shell wall . Review of the VIDs that captured the root passes of the ITCP for DSCs 13 and 16 (the only ITCP VID information available) observed a potential for LOF at locations around the circumference where the welding arc position did not remain centered on the weld groove. The fixed radial position of the weld head coupled with out-of-roundness of the shell wall caused the welding arc to drift away from the shell wall. This behavior is due to a lack of concentricity between the can ister shell and the radial position of the weld head as it travels around the circumference . As the shell wall moved further away from the welding arc, the molten weld puddle does not properly wash onto the shell wall , and LOF is favored and the welding arc must be repositioned . This behavior is consistent with the observed intermittent LOF indications that were seen along the shell wall associated with the root pass in DSC 16 PAUT inspection results .

The second bead or cap pass was deposited with the welding arc positioned closer to the shell wall as an expected good welding practice with the intention of facilitating good sidewall tie-in and to minimize any potential for LOF defects . The deposit was seen to build preferentially along the shell wall and tapers uniformly downward across the top surface of the root pass as it flows over the edge of the ITCP . The second pass will remelt a small amount of the top of the root bead and recast that material with the second bead . The second pass deposit on the shell side is clearly above the locations where the LOF was suspected . Consistent with the intended purpose of repositioning the welding arc, the results of the PAUT inspection on DSC 16 identified sidewall LOF defects located in the lower portion of the weld commensurate with the root pass tie-in to the sidewall. Further, all DSCs were welded using the same processes ,

procedures, equipment and welders . Shop floor video reviews confirmed similar practices were applied to all canisters . Thus , it is reasonable to expect that the welding arc positioning target would be similar for all canister ITCP welds .

The potential for alignment and stack-up of any LOF defects is further reduced by the remelting which will occur when the second pass remelts a small amount of the top of the root bead and recasts that material with the second bead.

From the SIA review of the shop floor videos , it was observed that DSCs 11 -15 experienced a greater amount of rework during the welding process than was observed for DSC 16 for both the ITCP and OTCP . These details are tabulated in Enclosure 3 to the exemption request. The performance of rework is an indication that the weld ing operators were alert to identifying unfavorable conditions as they developed during welding so that they could be corrected in -process . Therefore , it is reasonable to conclude that the probability for flaws in the closure welds of DSCs 11 -15 should be no greater, and perhaps lower than DSC 16 due to observed in -process of the repairs to correct undesirable features .

Page 10 of 14

L-MT-18-013 NSPM There were no observations suggesting that the second bead (cap pass) would produce additional sidewall flaws that might stack-up along the shell wall. To the contrary, significant and effective sidewall tie-in was observed at the shell wall for the second bead in both DSCs 13 and 16 ITCP closure welds . This effective tie -in was due to the closer proximity of the welding arc during the second pass.

NSPM determined that there is a reasonable expectation that flaws would not stack up along the canister shell wall in successive weld layers. This determination is based on the consistency in welders and processes, and associated shift in welding torch position towards the shell wall for its intended purpose of improved side-wall tie-in. The improved side-wall tie-in from the second layer will minimize potential for any possible flaw stack up along the canister shell wall. Beyond this conclusion, NSPM provided additional analyses to evaluate flaws maximized to identify the maximum flaw size that can be tolerated at the design thickness of the welds while still meeting the acceptable design limits .

PAUT examination on DSC 16 identified an actual weld thickness of 0.25" - 0.40" and an actual maximum flaw height of 0.11 " in the ITCP weld . This maximum flaw was extended to account for flaw uncertainties in DSCs 11 -15 up to 0.14". The analyses determined that a connected ligament of 0.05" (e.g., 0.14" flaw in a 0.19" thick weld, 0.20" flaw in a 0.25" thick weld) is sufficient to meet the design limits. Thus, the flaws modeled in Enclosures 4-8 to the exemption request were based on the PAUT results for DSC 16 and expanded to account for flaw uncertainties. Additionally, margin is demonstrated in the fact that the flaws identified via PAUT in DSC 16 were all intermittent in nature whereas the conservatively modeled flaws are full circumferential. Further margin is identified in Enclosures 7 and 8 to the exemption request which account for as-loaded temperature and pressure conditions and site-specific side-drop accident conditions.

RAI M-7 Clarify the size of the ITCP weld analyzed in the Enclosure 6, "NU HOMS 61 BTH Type 1 DSC ITCP and OTCP Maximum Weld Flaw Evaluation ," AREVA Calculation 11042-0207 ,

Revision 0. Section 3 (Design Input/Data) and Section 4 (Methodology) both reference ("61 BTH ITCP and OTCP Closure Weld Flaw Evaluation" AREVA Document No.

11042-0205 Revision 3). Enclosure 5 Section 3 (Design Input/Data) states the following:

The ITCP is 0.75" nominal thickness. Per the Reference 5.5 drawing , it is welded to the DSC shell and vent/siphon block with a 3/16" groove weld. However, the ITCP lid groove (weld prep) is 0.25" minimum , and it was confirmed that the weld is also 0.25." (Exemption Request for Nonconforming Dry Shielded Canister Dye Penetrant Examinations) page 29 of 75 states:

Page 11 of 14

L-MT-18-013 NSPM For the ITCP weld [ ... ]The analysis calculates the critical flaw size for a weld size of 0.25 inch per the PAUT results for DSC 16 (which indicated a distance between the root and crown at the canister wall from 0.25 to 0.40 inches) in lieu of the design thickness of 3/16 inch . This increased weld size is considered equally applicably to DSCs 11-15 based on the joint configuration and same weld ing process application .

Subsequently, Enclosure 1 page 32 of 75 references the analysis in Enclosure 6 . However, in the discussion of the results contained in Enclosure 6, page 33 of 75 of Enclosure 1 states:

The maximum modeled weld flaws for OTCP to DSC shell weld are 0.43 inch and 0.42 inch in height, which represents about 85% through -wall of the 0.5-inch minimum weld throat. The maximum modeled full-circumferential weld flaws for the ITCP to DSC shell weld are 0.16

  • cos(45°) = 0.11 inch and 0.14 inch in height, which represents respectively 58% and 74% through-wall of the 0.19-inch minimum weld throat as shown in Figure 7 (note that in Figure 7, weld heights are labeled as weld lengths).

These statements appear to be provide contradictory information and it is not clear whether the ITCP weld is modeled as the minimum design thickness or as the minimum measured thickness from the PAUT results for DSC 16.

This information is needed to complete the review in accordance with 10 CFR 72 .122(b).

NSPM Response The calculation provided as Enclosure 4 to the exemption request evaluated the critical flaw size based on the maximum radial stresses in the welds due to design loads. This analysis modeled a 0.25" weld. The calculation performed in Enclosure 5 to the exemption request evaluated DSC 16 flaw conditions . These analyses modeled the weld groove as 0.25";

however, the weld was modeled using the weld design thickness of 3/16". The detailed dimensions of the model are shown in Figure 4 of Enclosure 5 to the exemption request.

Conservatively, 0.09" and 0.11 " full circumferential flaws were modeled. Enclosures 6, 7, and 8 to the exemption request used the model developed in Enclosure 5 and , therefore , used an ITCP weld thickness of 3/16".

Structural RAls RAI ST-1 Provide the following ANSYS files used to analyze DSCs 11-15 in Enclosures 6 and 7, including load cases Internal Pressure 2D-Axisymmetric model and Side Drop 3D-Half-Symmetric model with extensions: .db , .inp, .err, .mntr, .out, .db, and .rst, and revise modeling descriptions presented in Section 4.1 of Enclosure 6 accordingly.

Page 12 of 14

L-MT-18-013 NSPM The aforementioned files are needed to verify modeling details which are not being sufficiently captured in a text format (exemption description). Modeling details regarding element type, distribution (mesh) , flaw depiction, constitutive material properties , and loading in both 20 and 30 space are most directly presented in the ANSYS files themselves . As an example on the need for clarifying modeling details description , the staff noted that, on page 6 of the enclosure, the applicant states (underscores added) :

Initial ANSYS finite element iterations were performed by increasing all the four flaws by a very small length resulting in a negligible increase in plastic strain . l.!:l the second step very large flaws where considered (leaving only one element of the model connected at each flaw) resulting in excessive strain for the elastic-plastic side drop analysis. Similarly, few more iterations were performed such that the weld flaw reaches close to acceptable strain limit for the elastic-plastic side drop analysis. Only the final flaw configuration is presented in the document.

Specifically, to add clarity to the above modeling description , the applicant needs to consider:

(1) If finite element iterations are not AN SYS inherent for a limit load analysis, describe the process of selecting and monitoring the flaw length increment, which resulted in a "negligible increase" in plastic strain , (2) Clarify whether or not the resulting "one element" configurations are realized to the limit load plastic hinge formation at the welds with maximized flaws by presenting appropriate finite element meshing annotation, which depicts nodal displacements for all the adjacent elements connected to the element incipient to the plastic hinges formation for the collapse load determination, (3) Revise , as appropriate , the statement, "[f]ew more iterations were performed ... for the elastic-plastic side drop analysis ," to recognize the "iteration" in context is ANSYS inherent for an elastic-plastic analysis methodology, and (4) Revise, as appropriate , the statement, "[s]uch that the weld flaw reaches close to acceptable strain limit," by recognizing that the elastic-plastic analysis is performed to demonstrate large strain ductility demand to be within the American Society of Mechanical Engineers (ASME) Code strain acceptance limits .

NSPM Response The requested ANSYS files are contained on a computer hard drive and are provided as 1 . The model from the calculation provided in Enclosure 5 to the exemption request was also used in the calculation provided in Enclosure 6 to the exemption request. 1 Therefore , model details like element types, mesh distribution , material properties , and loads were not repeated in Enclosure 6. Only the details of the variations were provided.

The intent of the word "iteration" was not the internal iterations AN SYS uses to obtain convergence in a non-linear analysis. Rather, the use of the word "iteration" was meant to illustrate the repetition of the analyses that were performed to obtain the largest flaw that can exist in OSCs 11-15 while ensuring maximum plastic strain remains below the ASME code acceptance limit. Section 4.1 of the calculation provided in Enclosure 6 to the exemption 1

The methodology used in Enclosures 4-8 to the exemption request is the same as used in Enclosures 2 and 4 to the exemption request for DSC 16 submitted on September 29, 2015 (ADAMS Accession No. ML15275A023),

which was granted by the NRC on June 15, 2016 (ADAMS Accession No. ML16167A035) .

RAI ST-2 Regarding Exemption Request Enclosure 1, revise the description of using stress in lieu of strain margin(s) of safety as a basis for demonstrating structural performance of DSCs 11-15 using the limit load and elastic-plastic analysis methodology. Page 2 of the enclosure noted that reasonable assurance of weld integrity is demonstrated by adequate stress margin in welds to accommodate flaws. The use of the word , "stress" does not reflect, in context, that only "strain " acceptance criteria in terms of ductility demands were considered in the closure weld evaluation . Similar descriptions in this and other enclosures may also need to be revised ,

as appropriate.

This information is needed to complete the review in accordance with 10 CFR 72.236(1).

NSPM Response 4 provides a markup of the affected pages to reflect the requested changes . While preparing the mark up pages being provided in response to RAI ST-2 , NSPM discovered a reference to an incorrect enclosure on pages 2 and 29 of 75 in Enclosure 1 to the exemption request. Mark-ups to reflect the proper references are included in Enclosure 14.

Enclosure 1 to E-51228 AFFIDAVIT PURSUANT TO 10 CFR 2.390 TN Americas LLC )

State of Maryland ) SS.

County of Howard )

I, Jeff Isakson, depose and say that 1 am a Vice President of TN Americas LLC, duly a uthori zed to execute this affidavit, and have reviewed or caused to have reviewed the information that is identified as proprietary and referenced in the paragraph immediately below. I am submi tting this affidavit in conformance with the provisions of 10 CFR 2.390 of the Commission's regulations for withholding this information.

The information for which proprietary treatment is sought meets the provisions of paragraph (a) (4) of Section 2.390 of the Commi ssion's regulations and is listed below:

  • Computer files associated with calculations 11042-0207 Rev. 1, 11042-0208 Rev. 0, and 11042-0209 Rev. 0 I have personal knowledge of the criteria and procedures utilized by TN Americas LLC in designating information as a trade secret, privileged or as confidential commercial or financial information.

Pursuant to the provisions of paragraph (b) (4) of Section 2.390 of the Commission's regulations, the fol lowing is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure, included in the above referenced document, should be withheld .

1) The information sought to be withheld from public disclosure involves com puter files related to calculations associated with the structural analysis of 6IBTH Dry Shielded Can ister (DSC) in the Standardized NUHOMS System, which are owned and have been held in confidence by TN Americas LLC.
2) The information is of a type customarily held in confidence by TN Americas LLC, and not customarily disclosed to the public. TN Americas LLC has a rational basis for determining the types of information customarily held in confidence by it.
3) Public disclosure of the information is likely to cause substantial harm to the competitive position of TN Americas LLC, because the information is related to the design and analys is of the dry spent fuel storage system, the application of which provides a competitive economic advantage. The availability of such information to competitors would enable them to modify their product to better compete with TN Americas LLC, take marketing or other actions to improve their product's position, or impair the position of TN Americas LLC ' s product, and avoid the development of similar data and analyses in support of their processes, methods, or apparatus.

Further the deponent sayeth not.

Jeff Isakson Vice President, TN Americas LLC Subscribed and sworn before me this 23th day of March, 2018.

Document Control Desk Page 2 License Issued under 10 CFR 72.210, for the Storage of Spent Fuel", dated November 4, 2013 (ADAMS Accession No. ML13310A568)

7) NSPM letter to NRC , "Project Plan Progress Toward Restoring 10 CFR 72 Compliance to Dry Shielded Canisters Designated 11 through 16", dated June 6, 2017 Pursuant to 10 CFR 72.7, "Specific Exemptions", the Northern States Power Company, a Minnesota corporation (NSPM) , doing business as Xcel Energy, requests an exemption from the requirements of 10 CFR 72.212(a)(2), 10 CFR 72.212(b)(3) , 10 CFR 72.212(b)(5)(i),

10 CFR 72.212(b)(11), and 10 CFR 72.214 for five NUHOMS Dry Shielded Canisters (DSCs) designated DSCs 11-15 due to nonconforming dye penetrant (PT) examinations performed during the loading campaign that started in September 2013. These nonconforming PT examinations are the subject of a Confirmatory Order (Reference 1).

Please note that an earlier submittal (Reference 2) was made to request an exemption for all six canisters (designated DSCs 11-16) that were originally found to be nonconforming.

However, that request was withdrawn (Reference 3) in 2014.

Pursuant to the NSPM corrective action program and the Confirmatory Order, DSC 16 was restored to compliance with the regulations by an exemption granted in June 2016 (Reference 4). Currently, the subject five DSCs are loaded into Horizontal Storage Modules (HSMs), as reported in References 5 and 6. The enclosed exemption request is structured as discussed in NSPM's most recent project plan update (Reference 7). strain In summary, the exemption request has determined that the integr" of the 1eld closure welds for DSCs 11-15 can be reasonably assured even though the Te nical Spec 1cation required dye penetrant examinations were nonconforming. The fuel cl ding integrity, eld design, materials, welding process, tests performed, adequate stress margin in the we to accommodate maximized representative flaws, and demonstration of additional stress margins to address any remaining uncertainties demonstrates the closure weld integrity of DSCs 11-15 is sufficient to ensure that the affected closure welds will continue to perform their design basis functions over the service lifetime of these canisters. In addition, the exemption request demonstrates that the consequences of non-mechanistic weld failures are very low and that the overall risk to the public is also very low. Enclosure 1 provides the exemption request including a description of the basis and technical justification for granting an exemption . The exemption request provides the basis and technical justification to permit continued storage of DSCs 11-15 in their respective HSMs. provides Structural Integrity Associates, Inc.

L-MT 053 NSPM is not a credible phenomenon . Service-induced flaws under normal and off-normal conditions of storage are not credible.

c. Material and Welding Process: Shell, lid, and weld filler quality requirements were met. Austenitic stainless steels do not have a nil ductility transition temperature and thus the weld can sustain "large" flaws without a concern for flaw growth . Weld process qualification, welder qualification , and the automated welding processes designed for the specific application all ensure a quality weld.
d. Tests Performed : In-process visual inspections of welds performed by the welders ,

Quality Control (QC) visual examination (VT) inspections of fit-ups and welds and the vacuum hold , helium pressure and helium leak test all ensured confinement and quality of the welds. k?7 ~..._s_tr_a_in_ _ _ _~

e. Adequate Street Margin in Welds to Accommodate Flaws: Stress margins were demonstrated by structural analysis using an analysis based stress allowance reduction factor, theoretically bounding full circumferential flaws, and a structural analysis assuming flaw distributions conservatively derived from Phased Array Ultrasonic Testing (PAUT) examination of DSC 16. A review of the weld head video ,

general area video, welding records, and DSC 16 was performed and determined that the indications found on DSC 16 are representative of those that might be found on DSCs 11-15. Additionally, it was determined that the same bounding analyses performed for DSC 16 should provide similar conservative results for the closure welds on DSCs 11-15. Regardless, further analyses have been performed to maximize the flaws located based on DSC 16 PAUT to demonstrate substantial margin to account for potential flaw uncertainties. These analyses are provided in Enclosures 2 through e,. < !6 I

f. Additional Stress Margins in Welds: DSCs 11-15 heat loads and site-specific side drop conditions were applied to demonstrate additional margin exists and is available to account for any remaining flaw uncertainty that may exist. These analyses are provided in Enclosures e throu~h 9.

2. Low Dose Consequences for a DSC in Storage : Notwithstanding the weld integrity demonstrated for DSCs 11-15, a reasonable assurance of safety is further supported by a radiological dose analysis. The dose analysis concludes that a non-mechanistic failure of the weld and a postulated release would result in no danger to the public as the dose consequences would be far below the regulatory limit of 5 rem Total Effective Dose Equivalent (TEDE) (Note: unless otherwise specified , all dose quantities identified in this Enclosure are TEDE). The dose analysis is provided in Enclosure 10.
3. Low Risk to the Public: Notwithstanding the weld integrity demonstrated for DSCs 11-15, a reasonable assurance of safety is further supported by a probabilistic risk assessment (PRA). This assessment concludes the risk of a potential Latent Cancer Fatality (LCF) for all five DSCs with noncompliant PT exams over a 20 year storage period is extremely unlikely (1 .39E-12 LCF) and the risk associated with the Page 2 of 75

L-MT-17-053 NSPM examination (i.e. , PT) vs. volumetric examination technique (i.e. , PAUT), and the potential for subsurface flaws to exist when only surface examinations are performed . Additionally, the maximum weld deposit depth for intermediate layers is kept smaller than the critical flaw depth in accordance with ISG-15.

b. Methodology for Assessing DSC 11-15 Closure Weld Structural Functions Previous analyses that demonstrated stress margins for the DSC 16 closure welds were provided to the NRC in Reference 6.7, and again in Enclosures 2, 4 and 5 to this letter. These evaluations included (1) structural analysis using an analysis-based stress allowance reduction factor and theoretically-bounding full-circumferential flaws, and (2) a structural analysis assuming flaw distributions conservatively derived from the DSC 16 PAUT examination .

To further evaluate the structural integrity of DSCs 11-15, evaluations were performed to determine if it was reasonable to expect that the types and extent of flaw distributions found in DSC 16 could be used to represent the comparable closure welds of DSCs 11-15 (Enclosure 3) and additional analysis was performed using design basis loads with flaws located based on DSC 16 PAUT and maximized such that the weld flaws reached close to acceptable design limits (Enclosure 6) .

Following these evaluations, additional analysis was performed using site-specific heat load and side drop conditions to demonstrate additional margin exists and is available to account for any remaining uncertainty related to the welds (Enclosures 7 and 8) . A description of each of these evaluations follows :

i. DSC 16 Closure Weld Flaw Evaluation
a. Analysis-Based Structural Analysis with Theoretical Flaws For the OTCP, the original design basis calculations determined critical flaw sizes. Per ISG-15, the stress reduction factor of partial penetration welds with PT examination is 0.80. Since these welds are noncompliant with the PT requirements , the weld reduction factor is reduced beyond 0.80 based on a set of theoretical flaw distributions that might conceivably have gone undetected during DSC closure weld examinations. Thus , an analysis-based stress allowable reduction factor of 0.7 was calculated . The analysis is included in its entirety in Enclosure 2. Since the original design basis critical flaw calculations already uses a reduction factor of 0.7 , the original analysis remains applicable. These design basis analyses determined for a 360° circumferential flaw, an allowable flaw depth of 0.19 inch and 0.29 inch could exist for surface connected and sub-surface flaws respectively. The flaw sizes determined by these calculations bound any of the indications found on DSC 16 by PAUT.

For the ITCP weld , the calculation provided in Enclosure 4 documents the critical flaw size based on the maximum radial stresses in the welds due to Page 28 of 75

L-MT-17-053 NSPM design loads. The analysis calculates the critical flaw size for a weld size of 0.25 inch per the PAUT results for DSC 16 (which indicated a distance between the root and crown at the canister wall from 0.25 to 0.40 inches) in lieu of the design thickness of 3/16 inch. This increased weld size is considered equally applicable to DSCs 11-15 based on the joint configuration and same welding process application . The calculation assumes both a buried (sub-surface) and a surface flaw. A 360° circumferential flaw was modeled and the critical flaw depth was calculated using ASME Section XI criteria. The critical flaw depth determined , 0.15 inches , is larger than the half of the weld which would exceed the typical weld layer. The original design basis calculation already considered a 0.7 stress reduction factor; therefore ,

no further analyses were performed to show that all component stresses remain below the stress allowable limits .

The flaw sizes determined by these calculations bound any of the indications found on DSC 16 by PAUT. Therefore, these calculations demonstrate that sufficient margin is included in the welds and indicates a reasonable expectation of satisfactory performance of each DSC for the design service lifetime of the DSC .

b. Structural Analysis Using PAUT Flaw Distribution: Enclosure 5 A structural analysis was performed assuming flaw stributions conservatively derived from DSC 16 PAUT exa
  • ation by applying bounding flaw heights and modeling the intermittent fla as full circumferential. This structural analysis is fully described in and concludes that DSC 16 will continue to perform its function due to the adequate margins for the accident pressure and drop loads with the presence of the ITCP and OTCP weld flaw indications documented in the PAUT exam.

ii. Applicability of DSC 16 PAUT to DSCs 11-15 As part of the original extent of condition review , weld head videos were reviewed by SIA in 2014. This review determined that good welding practices were used . However, the video also shows infrequent indications of areas where the potential for small weld flaws could exist. Both inner and outer cover plate closure welds were recorded in some cases , but the video coverage was incomplete for all weld beads. Specifically, the video review covered the ITCP root and cover weld layers; the OTCP tack, root, intermediate and cover weld layers for DSCs 13 and 16; and the OTCP tack, root, intermediate and cover weld layers for DSCs 12, 14 and 15. No weld head video was available for DSC 11. The DSC 16 outer closure weld was concluded to be the most vulnerable to potential defects , because a greater frequency of irregular surface conditions was generated during welding.

iii. Structural Analyses of DSCs 11-15 for Maximum Weld Flaw and Stress Margin Evaluation

a. Maximized Representative Flaw Evaluation Notwithstanding the conclusions reached by SIA that the bounding flaws used to model the DSC 16 PAUT results would be reasonable to assume for all canisters (DSCs 11-15), NSPM contracted with AREVA to evaluate DSCs 11 -15 closure welds per ASM E Section 111 criteria. The analysis used design basis loads with flaws located based on DSC 16 PAUT results and maximized such that the weld flaws reach close to acceptable design limits.

The purpose of this analysis was to address uncertainties related to the potential flaws that may be present in DSCs 11 -15 by demonstrating the maximum flaws that could be shown to still meet the code limits. The analysis is provided in its entirety in Enclosure 6.

All of the applicable design bases loading conditions are considered in accordance with the requirements of ASME Section Ill Subsection NB.

Similar to previous analysis, the uncertainties in the PAUT examination were accounted for by using a 0.8 reduction factor on the limit load and elastic plastic analyses.

The DSC design used in the calculation was typical of MNGP DSCs 11-16, and the modeled baseline flaws were representative of those indications Page 32 of 75

b. Additional Stress Margins in Welds Notwithstanding the conclusions re che by SIA that the bounding flaws used to model the DSC 16 PAUT results would e reasonable to assume for DSCs 11-15, and the analysis by A EVA sh wing large flaws that could still be shown to meet the code limits, ditional a lyses were performed by AREVA to demonstrate additional stress margin xists using site-specific heat loads and side drop conditions. The purpose of th e analyses was to address any remaining uncertainties related to pote
  • I flaws that may be present in DSCs 11-15 by demonstrating additional stress margins. These analyses are provided in their entirety in Enclosures 7 and 8.

Enclosure 7 evaluates the margins for DSCs 11-15 with the maximum flaws in the ITCP and OTCP closure welds based on the as-loaded temperature and pressure conditions.

Load Limit Analysis: The lower bound collapse pressure for Service Level A/B criteria was found to be 98.4 psi which is greater than the limiting pressure of 60 psi. Therefore the Service Level A/B criterion is satisfied.

The lower bound collapse pressure for Service Level D criteria was found to be 144.1 psi which is greater than the limiting pressure of 90.2 psi. The lower bound collapse G-Load for Service Level D side drop criteria was found to be 204 g which is greater than the limiting G-Load of 104 g.

Therefore the Service Level D criterion is satisfied .

Elastic-Plastic Analyses: The peak strains predicted by the elastic-plastic analyses for the bounding Service Level D event are shown to remain below the material ductility limits (28%) at the specified loading conditions, and also at one and a half times the specified loads, with a minimum margin of safety of 1.86. Therefore the elastic plastic analyses criteria are satisfied.

Enclosure 8 evaluates margins for the DSCs with the maximum flaws in the ITCP and OTCP closure welds based on the as-loaded temperature and pressure conditions, and the site specific side drop loads (i.e., actual approach slab parameters).

Limit Load Analysis: The lower bound collapse G-Load for Service Level D side drop criteria was found to be 204 g which is greater than the limiting G-Load of 104 g. Therefore the Service Level D criterion is satisfied.

Elastic-Plastic Analysis: The peak strain values remain below the material ductility limits at the specified loading conditions with a minimum margin of Page 34 of 75

L-MT-17-053 NSPM Enclosure 1 safety of 3.83. Therefore the elastic plastic analyses criteria are satisfied.

It should be noted that with the as-loaded temperature and pressure conditions, and site specific side drop loads the margin of safety is higher than the margin of safety in similar analyses for DSC 16 (3.83 vs. 3.60).

Additionally, the analysis used to determine the bounding DSC shell temperature and internal pressure during storage operations based on the as-loaded configuration of DSCs 11-15 is included as Enclosure 9.

3.7 Conclusion Based on the technical assessment presented previously, the proposed activity does not adversely affect the criticality safety, shielding/radiological safety, heat removal, confinement integrity or structural support functions of DSCs 11-15 as described in the UFSAR. In summary, the requested exemption results in continued safe oper"'ra "=t=io~n~o

The integrity of the field closure welds for DSCs 11-15 can be assured with confidenc even though the TS-required PT examinations were nonconforming. The fuel cladd" g integrity, weld design , materials , welding process, tests performed, adequate stress margins in the welds to accommodate the maximized representative flaws, and demonstration of additional stress margins to address any remaining uncertainties demonstrates the closure weld integrity of DSCs 11-15 is sufficient to ensure that the affected closure welds will continue to perform their design basis functions over the service lifetime of these canisters.

Application of the alternatives described in Section 4.3 would increase the radiological dose to workers , generate additional radiological waste, potentially create foreign material concerns and increase other operational risks to the station without a commensurate increase in safety as compared to receipt of the exemption request.

4.0 Basis for Approval The proposed exemption is limited in scope in that it only relates to compliance with the inspection of certain field closure welds. The proposed exemption involves a change in compliance , but no physical change to the canister design , and no change to the canister materials or the loading operation. In this regard , the proposed activity cannot affect the frequency of any accident caused by the loading process (e.g., dropped TC or jammed DSC).

It has no bearing on the frequency of natural events (flood , earthquake, tornado) that are natural phenomena. Therefore, the proposed activity does not result in an increase in the frequency of any previously evaluated accident. Furthermore, since the exemption does not affect the canister design and procedures this ensures that no new type of malfunction would be created.

The Technical Assessment herein provides the basis for the conclusion that a reasonable assurance of safety exists for the service lifetime of DSCs 11-15. Even though regulations Page 35 of 75 L_

c. Material and Welding Process: The shell, lid, and weld filler quality requirements were met. Austenitic stainless steels do not have a nil ductility transition temperature and thus the weld can sustain "large" flaws without a concern for flaw growth. Weld process qualification, welder qualification, and automated welding processes designed for the specific application all ensure a quality weld.
d. Tests Performed : The welding procedures used for this campaign required welder in-process inspections prior to each QC NOE examination to ensure a weld surface free of coarse ripples , arc strikes, coarse grooves, overlap, abrupt ridges and valleys, cracks, porosity or fish-eyes, lack of fusion , lack of penetration , undercut in excess of 1/32 inch or root concavity that results in less than minimum wall. QC VTs were required for fit-up and tack welds of the ITCP, siphon cover, vent cover, and OTCP joints.
