[t]he table [referring to the soil corrosivity sampling results table] does not include an outlier soil sample associated with a Unit 2 intake cooling water (ICW) line, since that sample had been impacted by local saltwater foaming from the ICW discharge overflow/standpipe. The caulking between the standpipe and the concrete decking was weathered and porous, allowing saltwater foam to permeate into the soil.
In response to RAI B.2.3.21-2, the applicant provided results from seven soil corrosivity samples which included the following parameters: pH, soil resistivity, moisture, chlorides, sulfates, redox potential, and microbiology. Based on its review of this data, the staff noted that the soil can be considered appreciably corrosive (using average values) or severely corrosive (using least conservative values) to stainless steel when scoring in accordance with Table 9-4, Soil Corrosivity Index from BPWORKS, of Electric Power Research Institute (EPRI) Report 3002005294, Soil Sampling and Testing Methods to Evaluate the Corrosivity of the Environment for Buried Piping and Tanks at Nuclear Power Plants.
In response to RAI B.2.3.21-2, the applicant provided results from seven soil corrosivity samples which included the following parameters: pH, soil resistivity, moisture, chlorides, sulfates, redox potential, and microbiology. Based on its review of this data, the staff noted that the soil can be considered appreciably corrosive (using average values) or severely corrosive (using least conservative values) to stainless steel when scoring in accordance with Table 9-4, Soil Corrosivity Index from BPWORKS, of Electric Power Research Institute (EPRI) Report 3002005294, Soil Sampling and Testing Methods to Evaluate the Corrosivity of the Environment for Buried Piping and Tanks at Nuclear Power Plants.
Issue The basis provided by the applicant for having uncoated buried stainless steel (i.e., an exception to GALL-SLR AMP XI.M41 guidance) is that the piping is not exposed to significant amounts of moisture (i.e., wetting). However, the staff notes that soil parameters beyond moisture (i.e., pH, soil resistivity, chlorides, sulfates, redox potential, and microbiology) impact the susceptibility of buried stainless steel to external corrosion. Based on the soil corrosivity data provided in the response to RAI B.2.3.21-2, the environment at St. Lucie can be considered corrosive to buried stainless steel. In addition, based on its review of the response to RAI B.2.3.21-2, the staff notes that there has been at least one incident of saltwater intrusion into the soil. Based on its review of Table 9-4 of EPRI Report 3002005294, the staff also notes buried stainless is more sensitive to the effects of chlorides than any other material type.

Although stainless steel is susceptible to attack by chlorides, such attacks are primarily catalyzed when moisture breaks the chloride molecules ionic bonds freeing chlorine ions to attack the stainless steel piping. The concrete floor slab associated with the turbine building shields the piping from rainwater, saltwater, and other moisture or chloride intrusion. Even if moisture intrusion occurred, sand is known to have relatively good drainage properties, so stagnant moisture leading to a continued chloride attack would not occur. Additionally, as identified in the response to Set 1 RAI B.2.3.21-2, the majority of the soil samples listed had chloride and sulfate readings below the threshold of detection. The two exceptions to this were at soil samples near the intake cooling water (ICW) piping on the intake side of the plant, which measured 205 mg/kg dry chlorides and 149 mg/kg dry sulfates, and the outlier sample near the discharge structure where saltwater intrusion had occurred (Reference 3). Neither of the two outlier sample locations are near any of the subject grade 316 stainless steel piping.

Due to the low number of chlorides within the soil, the low likelihood of stagnant moisture due to the concrete floor slab shielding, good soil/backfill drainage, and no history of negative OE, an exception to the NUREG-2191 recommendation of coating buried stainless steel piping as a preventive action is reasonable and will be taken with respect to the Unit 1 stainless steel AFW pump recirculation piping and condensate system (AFW pump suction) piping buried beneath the Unit 1 turbine building. Additionally, for the same reasoning, the inspection quantities listed in NUREG-2191 Table XI.M41-2 are adequate for providing reasonable assurance that the uncoated buried stainless piping at St. Lucie will maintain its pressure boundary function throughout the SPEO.

St. Lucie Units 1 and 2 Dockets 50-335 and 50-389 PSL Response to NRC RAI No. B.2.3.27-1a L-2022-143 Attachment 1 Page 1 of 42 Buried and Underground Piping and Tanks AMP RAI B.2.3.27-1a Regulatory Basis Section 54.21(a)(3) of Title 10 of the Code of Federal Regulations (10 CFR) requires an applicant to demonstrate that the effects of aging for structures and components will be adequately managed so that the intended function(s) will be maintained consistent with the current licensing basis for the period of extended operation. One of the findings that the U.S.

Nuclear Regulatory Commission (NRC) staff must make to issue a renewed license (10 CFR 54.29(a)) is that actions have been identified and have been or will be taken with respect to managing the effects of aging during the period of extended operation on the functionality of structures and components that have been identified to require review under 10 CFR 54.21, such that there is reasonable assurance that the activities authorized by the renewed license will continue to be conducted in accordance with the current licensing basis. In order to complete its review and enable making a finding under 10 CFR 54.29(a), the staff requires additional information in regard to the matters described below.

Background

SLRA Section B.2.3.27, Buried and Underground Piping and Tanks, states [t]he number of inspections for each 10-year inspection period, commencing 10 years prior to the start of SPEO, are based on the inspection quantities noted in NUREG-2191, Table XI.M41-2, adjusted for a 2-Unit plant site.

GALL-SLR Report Table XI.M41-1, Preventive Actions for Buried and Underground Piping and Tanks, recommends that buried stainless steel piping is externally coated in accordance with the preventive actions program element of GALL-SLR Report AMP XI.M41, Buried and Underground Piping and Tanks.

In addition, GALL-SLR Report AMP XI.M41 states the following:

x

[a]dditional inspections, beyond those in Table XI.M41-2, Inspection of Buried and Underground Piping and Tanks, may be appropriate if exceptions are taken to program element 2, preventive actions, or in response to plant-specific operating experience.

x

[t]here are no recommended preventive actions [e.g., external coatings] for titanium alloy, super austenitic stainless steels, and nickel alloy materials.

By letter dated June 13, 2022 (ADAMS Accession No. ML22164A802), the applicant stated the following in response to RAIs B.2.3.27-1 and B.2.3.21-2 (respectively):

x

[a] portion of the Unit 1 auxiliary feedwater (AFW) and condensate system (AFW pump suction) is buried stainless steel piping in sand beneath the turbine building. No coating was identified, however, due to the location beneath the turbine building, this buried piping is not susceptible to wetting.

St. Lucie Units 1 and 2 Dockets 50-335 and 50-389 PSL Response to NRC RAI No. B.2.3.27-1a L-2022-143 Attachment 1 Page 2 of 42 x

[t]he table [referring to the soil corrosivity sampling results table] does not include an outlier soil sample associated with a Unit 2 intake cooling water (ICW) line, since that sample had been impacted by local saltwater foaming from the ICW discharge overflow/standpipe. The caulking between the standpipe and the concrete decking was weathered and porous, allowing saltwater foam to permeate into the soil.

In response to RAI B.2.3.21-2, the applicant provided results from seven soil corrosivity samples which included the following parameters: pH, soil resistivity, moisture, chlorides, sulfates, redox potential, and microbiology. Based on its review of this data, the staff noted that the soil can be considered appreciably corrosive (using average values) or severely corrosive (using least conservative values) to stainless steel when scoring in accordance with Table 9-4, Soil Corrosivity Index from BPWORKS, of Electric Power Research Institute (EPRI) Report 3002005294, Soil Sampling and Testing Methods to Evaluate the Corrosivity of the Environment for Buried Piping and Tanks at Nuclear Power Plants.

Issue The basis provided by the applicant for having uncoated buried stainless steel (i.e., an exception to GALL-SLR AMP XI.M41 guidance) is that the piping is not exposed to significant amounts of moisture (i.e., wetting). However, the staff notes that soil parameters beyond moisture (i.e., pH, soil resistivity, chlorides, sulfates, redox potential, and microbiology) impact the susceptibility of buried stainless steel to external corrosion. Based on the soil corrosivity data provided in the response to RAI B.2.3.21-2, the environment at St. Lucie can be considered corrosive to buried stainless steel. In addition, based on its review of the response to RAI B.2.3.21-2, the staff notes that there has been at least one incident of saltwater intrusion into the soil. Based on its review of Table 9-4 of EPRI Report 3002005294, the staff also notes buried stainless is more sensitive to the effects of chlorides than any other material type.

Request

1. State the approximate length of uncoated in-scope buried stainless steel piping.
2. State the basis for why the inspection quantities in GALL-SLR Report Table XI.M41-2 are appropriate for buried stainless steel piping. The technical basis could include (but is not limited to) discussion of the following: results of soil corrosivity testing in the vicinity of the subject piping, results of inspections of buried uncoated stainless steel piping, and type(s) of in-scope stainless steel (e.g., super austenitic) piping utilized in uncoated buried applications, etc.

St. Lucie Units 1 and 2 Dockets 50-335 and 50-389 PSL Response to NRC RAI No. B.2.3.27-1a L-2022-143 Attachment 1 Page 3 of 42 PSL Response:

The only buried stainless steel piping at St. Lucie, which could not be confirmed as coated or encased in concrete, is comprised of the Unit 1 auxiliary feedwater (AFW) pump recirculation piping and condensate system (AFW pump suction) piping. Therefore, this piping is conservatively assumed to be uncoated. This grade 316 stainless steel piping traverses beneath the Unit 1 turbine building and has a total length of approximately 520 ft.

At St. Lucie, the application of external coatings on safety-related piping is a design feature and is controlled by engineering specifications and design drawings, as appropriate. The St. Lucie Unit 1 design specifications and drawings for buried stainless steel piping do not specify the application of a coating material.

NUREG-2191, Table XI.M41-1 identifies coatings and backfill as preventative actions for buried stainless steel piping. The Unit 1 buried grade 316 stainless steel piping meets the backfill preventive action in Table XI.M41-1. The soil environment in contact with this buried stainless steel piping is composed of backfill in accordance with the applicable plant specification, which is available on the ePortal and summarized as follows:

x Material to be used as compacted backfill for Unit 1 shall be a selected sand and be free of muddy material, organic matter, rubbish, debris, or other unsuitable materials. The moisture content of the sand shall be within the limits required to obtain the specified compaction. Dredged material shall be stockpiled so as to facilitate drainage. No limerock shall be used for fill. This meets and exceeds the NACE SP0169-2007 (Reference 1), Section 5.2.3.4 backfill recommendation from NUREG-2191.

x Backfill material designated as Class I material for Unit 1 shall have no more than 12%

silt content (finer than No. 200 sieve), be free of clay balls, and no rock fragments larger than 6 inches shall be used for the fill except in areas where hand compaction is required wherein the maximum rock fragment size shall not exceed 3 inches. Sieve analyses are performed in accordance with ASTM D422 or D1140. Only Class I backfill is used at St. Lucie. This meets and exceeds the ASTM D 448-08 (Reference 2) size recommendation from NUREG-2191.

Although stainless steel is susceptible to attack by chlorides, such attacks are primarily catalyzed when moisture breaks the chloride molecules ionic bonds freeing chlorine ions to attack the stainless steel piping. The concrete floor slab associated with the turbine building shields the piping from rainwater, saltwater, and other moisture or chloride intrusion. Even if moisture intrusion occurred, sand is known to have relatively good drainage properties, so stagnant moisture leading to a continued chloride attack would not occur. Additionally, as identified in the response to Set 1 RAI B.2.3.21-2, the majority of the soil samples listed had chloride and sulfate readings below the threshold of detection. The two exceptions to this were at soil samples near the intake cooling water (ICW) piping on the intake side of the plant, which measured 205 mg/kg dry chlorides and 149 mg/kg dry sulfates, and the outlier sample near the discharge structure where saltwater intrusion had occurred (Reference 3). Neither of the two outlier sample locations are near any of the subject grade 316 stainless steel piping.

St. Lucie Units 1 and 2 Dockets 50-335 and 50-389 PSL Response to NRC RAI No. B.2.3.27-1a L-2022-143 Attachment 1 Page 4 of 42 An operating experience (OE) search of the 10-year action request (AR) database and component database (NAMS) did not identify any aging-related degradation for the Unit 1 stainless steel AFW and condensate system piping buried beneath the Unit 1 turbine building nor was age-related degradation identified for any other buried stainless steel piping at the site.

Due to the low number of chlorides within the soil, the low likelihood of stagnant moisture due to the concrete floor slab shielding, good soil/backfill drainage, and no history of negative OE, an exception to the NUREG-2191 recommendation of coating buried stainless steel piping as a preventive action is reasonable and will be taken with respect to the Unit 1 stainless steel AFW pump recirculation piping and condensate system (AFW pump suction) piping buried beneath the Unit 1 turbine building. Additionally, for the same reasoning, the inspection quantities listed in NUREG-2191 Table XI.M41-2 are adequate for providing reasonable assurance that the uncoated buried stainless piping at St. Lucie will maintain its pressure boundary function throughout the SPEO.

selected for buried steel piping after the cathodic protection system has been in service for approximately 10 years and annual effectiveness reviews are performed.

However, if these conditions were to change, the Preventive Action Category would require reevaluation and could potentially change.

The number of inspections for each 10-year inspection period, beginning 10 years before the SPEO, are based on the inspection quantities noted in NUREG-2191, Table XI.M41-2, adjusted for a 2-Unit plant site.

Material No. of Inspections Notes Steel (buried) 11* prior to the SPEO (Category F) 4 in each 10-year period in the SPEO (Category C)

Includes 2 additional inspections to meet the requirements of NUREG-2191 Section XI.M41, paragraph 4.e.i regarding the aging effects associated with fire mains.

Steel (underground) 3 Stainless steel (underground)

Pressure testing per note Perform periodic pressure testing and blow-out testing (purging) with air or nitrogen of the annular volume between the underground stainless steel fuel oil piping and its respective guard piping to verify no leakage of guard pipe and no leakage from the fuel oil piping. This testing will be performed for at least 25 percent of the stainless steel fuel oil piping housed within guard piping at an interval not to exceed 5 years with the first occurrence prior to the SPEO. The annular volume between the fuel oil piping and guard piping will be pressurized to 110 percent of the design pressure of any component within the boundary (not to exceed the maximum allowable test pressure of any non-isolated components) with test pressure being held for a continuous eight hour interval.

  • If after five years of operation the cathodic protection system does not meet the effectiveness acceptance criteria defined by NUREG-2191, Tables XI.M41-2 and -3 (-850 mV relative to a CSE, instant off, for at least 80 percent of the time, and in operation for at least 85 percent of the time), FPL commits to performing two additional buried steel piping inspections beyond the number required by Preventive Action Category F resulting in a total of thirteen (13) inspections being completed six months prior to the SPEO. The cathodic protection criterion listed above will continue to be used after five years through the end of the SPEO.

This AMP does not provide aging management of selective leaching. The PSL Selective Leaching of Materials (Section B.2.3.21) AMP is applied in addition to this program for applicable materials and environments.

The PSL Buried and Underground Piping and Tanks AMP requires the creation of new governing and inspection procedures consistent with NUREG-2191,Section XI.M41, as well as a new sampling plan and work orders to support the new inspections. A new cathodic protection system will also be installed, and an effectiveness review per Table XI.M41-2 of NUREG-2191,Section XI.M41 will be performed throughout each of the 10-year inspection periods. Initial inspections begin 10 years before to the SPEO and are completed no later than six months prior to entering the SPEO or no later than the last RFO prior to the SPEO.

NUREG-2191 Consistency The PSL Buried and Underground Piping and Tanks AMP will be consistent without exception to the 10 elements of NUREG-2191,Section XI.M41, Buried and Underground Piping and Tanks.

Exceptions to NUREG-2191 None. An exception to the NUREG-2191 recommendation of coating buried stainless steel as a preventive action will be taken with respect to the Unit 1 stainless steel AFW pump recirculation piping and condensate system (AFW pump suction) piping buried beneath the Unit 1 turbine building. This exception is justified due to the low number of chlorides within the soil, the low likelihood of stagnant moisture due to the concrete floor slab shielding, good soil/backfill drainage, and no history of negative OE for buried stainless steel piping at St. Lucie.
