1 INTRODUCTION On behalf of the General Electric Company, Arcadis U.S., Inc. (Arcadis) has prepared this Addendum to the May 2019 Cleanup Plan (Addendum) for the former United Nuclear Corporation Naval Products Facility, located in New Haven, Connecticut (Site).
The project was initiated in September 2019, and work has progressed in accordance with the May 2019 Cleanup Plan (Cleanup Plan). To date, the above-grade portions of Building 3H and Building 6H; and the at-grade concrete slab, underlying trenches and foundations, and soil associated with Building 3H and a portion of Building 6H immediately adjacent to Building 3H have been transported offsite for disposal at approved disposal facilities.
Based on the analytical results from the previous building characterization activities performed in 2018/2019 and presented in the Cleanup Plan, and recent comprehensive intrusive sampling activities (March/April 2020), the concrete slab in the remaining portion of Building 6H is not impacted by radiological or hazardous constituents and is amenable to off-site disposal as non-hazardous/non-radioactive waste. It is also anticipated that the sub-slab features beneath the remaining slab (i.e., building and equipment foundations and portions of the trench structures), as well as the underlying soil will not be impacted, and that they will also be amenable to disposal as non-hazardous/non-radioactive waste. As discussed in this Addendum, additional characterization of the sub-slab features and underlying soil will be performed once accessible to confirm this assumption and prior to off-site disposal.
The purpose of this Addendum is to include waste material release criteria and additional disposal options for the non-hazardous/non-radioactive waste materials associated with the remaining portions of Building 6H and underlying materials. Appendix A of this Addendum also includes revisions to the figures and tables that were included in the Cleanup Plan; the revisions reflect sample labeling nomenclature.
2 SOLID MATERIALS RELEASE CRITERIA According to NUREG-1757 Consolidated Decommissioning Guidance: Decommissioning Process for Material Licensees (NRC,2006) solid materials may be released from licensed operation with the acknowledgement that the material may contain very low levels of radioactivity. Furthermore, Fuel Cycle Policy and Guidance Directive (FC 83-23) Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct, Source, or Special Nuclear Material (NRC 1993) establishes surface contamination limits for natural uranium, U-235, U-238 and associated decay products (Table 1).
Table 1. FC 83-23 Acceptable Surface Contamination Levels Nuclidesa Averageb, c, f Maximumb, d, f Removableb, e, f Natural uranium, U-235, U-238 and associated decay products 5,000 dpm /100 cm2 15,000 dpm /100 cm2 1,000 dpm /100 cm2

Notes for Table 1 are as follows:
a where surface contamination by both alpha-and beta-gamma emitting nuclides exists, the limits for alpha-and beta-gamma-emitting nuclides should be applied independently.
b As used in this table, dpm (disintegrations per minute) means the rate of emission by radioactive materials as determined by correcting the counts per minute observed by the detector for background, efficiency, and geometric factors associated with the instrumentation.
c Measurements of average contaminant should not be averaged over more than 1 square meter.
For objects of less surface area, the average should be derived or each such object.
d The maximum contamination level applies to the area not more than 100 cm2.
e The amount of removable radioactive material per 100 cm2 of surface area should be determined by wiping that area with dry filter or soft absorbent paper, applying moderate pressure, and assessing the amount of radioactive material on the wipe with an appropriate instrument of know efficiency. When removal contamination on objects of less surface area is determined, the pertinent levels should be reduced proportionally, and the entire surface should be wiped.
f The average and maximum radiation levels associated with surface contamination results in from beta-gamma emitters should not exceed 0.2 mrad/hr at 1 cm and 1.0 mrad/hr at 1 cm, respectively, measured through not more than 7 milligrams per square centimeter of total absorber.
For solid materials such as concrete, these materials may be surveyed using a representative sample and gamma spectroscopy methods (NRC,2002). NUREG-1757 (NRC,2006) specifies that materials can be released if no radioactive material is above natural background levels. The background soil concentration for the Site was previously determined and accepted by NRC as 3.43 picocurie per gram (pCi/gram) uranium (AAA/IEM, 2005).
3 WASTE ASSESSMENT AND DISPOSAL OPTIONS The results of the radiological surveys performed for Building 6H concrete slabs in March/April 2020 meet the release criteria presented in Section 2. In addition, sampling of the concrete for non-radiological parameters determined (as anticipated) that the concrete is not a hazardous waste. As a result, this material is suitable for local off-site disposal at Modern Materials Corporation in Hamden, Connecticut or another Connecticut--based or out-of-state recycling facility permitted to accept this material. Sampling results and protocols (e.g., number of sample locations, sample collection, radiological measurements, and analytical parameters) are presented in Appendix B.
Once the remaining slabs are removed, the sub-slab features (e.g., concrete equipment foundations and trenches) and underlying soil associated with Building 6H will be assessed for the presence of radiological and hazardous constituents using the same sampling approach and methodologies that were applied to the concrete slab in Building 6H (Appendix B). Evaluation of the materials as possible hazardous waste will be through visual inspection and sampling and analytical determination for total PCBs and Toxicity Characteristic Leachate Procedure (TCLP) analyses for VOCs, SVOC, and Inorganics.

Assessment of the sub-slab features will be accomplished through grab and composite sample collection and both radiation and non-radiation laboratory analyses as described below:
For soil underlying the concrete slabs, composite sample collections within each subarea will follow the grid used for the slab, as presented on Figure 1, except in locations where trench or equipment foundations are encountered during slab removal operations.
Surface contamination of concrete equipment foundations will be analyzed prior to breaking up the concrete for removal purposes. Fixed and removable alpha surveys will be performed in a systematic grid, depending upon the size of the foundation.
Volumetric concrete sample of foundations will be taken as appropriate. Concrete samples will be collected from equipment foundations and trenches (if they are present), depending on size. Discrete samples will be collected from equipment foundations less than 400 square feet and trenches up to 20 feet long, otherwise a minimum two-point composite concrete samples will be collected.
If the results of the assessment sampling activities meet the waste release criteria discussed in Section 2, these materials can also be disposed of as non-hazardous/non-radioactive waste materials at Modern Materials Corporation or another Connecticut-based or out-of-state recycling facility that can accept this material.
4 REVISED FIGURES AND TABLES FROM MAY 2019 CLEANUP PLAN In response to a recent on-site audit comments provided by NRC, the figures and tables associated with May 2019 Cleanup Plan submittal have been revised so that all sampling nomenclature is consistent. The revised figures and tables are contained in Appendix A.

1 SAMPLING METHODOLOGY Appendix B presents the methodology used to conform to the Nuclear Regulatory Commissions (NRCs) approach for release of solid materials. This includes radiological survey methodology, instrumentation used to conduct the current surveys, and minimum detectible concentrations of the instrumentation for the contaminants of concern, The basis for the number of samples sent for analysis for radiological and hazardous waste constituents is also presented.
The results of the current radiological and hazardous waste surveys and sample results are presented along with a discussion of the results of prior gamma walkover survey and alpha surface survey performed by Cabrera reported in their Supplemental Radiological Survey Report, March 2018 (Cabrera, 2018).
1.1 Survey Methods In December 2002, a memorandum was issued by NRC headquarters licensing divisions presenting the approach that should be used regarding controlled release of concrete from licensed facilities (NRC, 2002).
This memo was reaffirmed in the NRCs Consolidated Decommissioning Guidance -Decommissioning Process for Material Licensees. Vol 1 Revision 2, (NRC, 2006). The memorandum noted release of solid materials on a case-by-case basis using existing guidance with the following criteria:
A) Sites should assess surficial contamination of concrete based on process knowledge and verified by appropriate core samples to confirm that the concrete does not contain contamination beyond a depth that can be measured by the instrumentation used for the survey.
B) Survey instruments should be used that are appropriate for evaluating the radioactive contamination of interest and all accessible surfaces should be evaluated. The number of core samples and the method for determining the depth at which a survey instrument can measure below the surface of the concrete should be determined on a case-specific basis.
C) Disposition of concrete with surficial contamination should be evaluated using Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct, Source, or Special Nuclear Material, dated April 1993, which is based on Fuel Cycle Policy and Guidance Directive 83-23. There is no upper limit on the amount of concrete with surficial contamination that can be released from a materials site if it meets criteria contained in the April 1993 guidance document.
D) Surveys for the clearance of concrete with surficial contamination should be conducted before the concrete floor or wall is broken up. If the concrete wall or floor has been broken up, then it is considered a volumetric source of contamination.
These methods will be used to evaluate the remaining portion of the Building 6H concrete slab, foundations, and underlying soils and other miscellaneous concrete materials.
1.2 Minimum Detectible Concentration All radiological measuring instruments (probes and ratemeter/scalers) were selected based upon detection sensitivity to provide technically defensible results to meet the objectives of the survey. The minimum detectable concentration (MDC) is an a priori statement of instruments sensitivity and depends upon the background counting rate, detector efficiency, and counting time.

Gamma scanning surveys were performed using a Ludlum 44-10, 2-inch by 2-inch sodium iodide (NaI) detector coupled with a Ludlum 2221 ratemeter/scaler. Per Table 6.7 of MARSSIM (NRC, 2000), the scan MDC for a 2-inch by 2-inch sodium iodide detector ranges from 96 to 132 pCi/g for enriched uranium (depending on the percent enrichment).
Alpha/Beta scanning surveys were performed using a Ludlum 43-89 alpha/beta detector which has a 126 cm2 active window. Per Table 6.4 of MARSSIM (NRC,2000), the scan MDC for U-238 using an alpha scintillation detector with 50 cm2 is 90 dpm/100 cm2. The Ludlum 43-89 probe with 126 cm2 will have a lower MDC.
For volumetric samples the lower limit of detection was consistent with the detection level needed to evaluate environmental samples. Sample will be analyzed by a vendor laboratory for U-238, U-235 and U-234 by alpha spectroscopy method DOE A-01-R and U-235 and U-238 (thorium-234) by gamma spectroscopy method DOE GA-01-R (EML300).
1.3 Number of Sample Locations The number of sample locations was based upon the relative shift between the concentration and the standard deviation of the measurement, and the errors associated with the measurements as presented in NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (NRC, 2000). MARSSIM equation 5-2 approximates the number of data points (N) for a survey unit.
=
( )
(.)
Equation 1 The value of the relative shift (/) is typically selected as a value between 1 and 3. A relative shift of 2.0 was selected; giving rise to a MARSSIM Table 5.4 Sign P of 0.977. A Type I error is sometimes called a false positive. The probability of a Type I error is usually denoted by. A Type II error is sometimes called a false negative. The probability of a Type II error is usually denoted by. Consequences of Type I error is releasing of material with radioactivity higher than the release criterial. Consequence of Type II errors include unnecessary remediation expense and project delays. The error rate for (Type I error) and (Type II error) were selected as 0.05 and 0.05, which results in a Z1-and Z1-of 1.645 and 1.645, respectively.
Using Equation 1, this results in a minimum number of 11.9 sample points required to evaluate the slab and underlying soils. To account for unusable measurements, the number of sample point is increased by 20%.
Thus, a minimum of 15 systematic samples will be performed on a grid. The actual number of sample points may be increased to account for geometric differences and interferences. A systematic rectangular sampling grid will be aligned with the existing building column lines which are spaced 16 feet apart.

SUMMARY
OF RADIATION ANALYTICAL RESULTS Characterizations and waste profile analysis were performed upon the remaining concrete slab surfaces of Building 6H to meet the guidance of NUREG-1757 and FC 83-23. These characterizations and waste profile analyses include:

- 1. Gamma walkover survey performed by Cabrera of the floor area (Supplemental Radiological Survey Report, March 2018-Cabrera, 2018).
- 2. A alpha / beta one-minute integrated measurements on 74% of the accessible area in 6H/3H performed by Cabrera (Cabrera, 2018).
- 3. Arcadis concrete core samples (December 2018 and April 2019).
- 4. Arcadis concrete core samples (March 2020).
- 5. Arcadis concrete surface contamination (smear) and alpha/beta survey (April 2020).
- 6. Arcadis gamma scan of floor area sample locations (April 2020).
In summary, the data collected to date indicates that the remaining Building 6H concrete slab meets all relevant release criteria and contains no radiological component. Collectively, these results indicate that the foundation material has no radiological component other than NORM.
2.1 Gamma Scan Results Cabrera conduced a gamma walkover survey of accessible areas of the overall Building 6H footprint. The figures discussed below are reproduced in Appendix A. For Column Line 1 to Column Line 14 the accessible area was between 75 and 100 percent. For Column Line 14 to Column Line 26 the accessible area was between 25 and 50 percent as shown in Figure B1 (Figure 1-2, Cabrera 2018). The gamma scan was continuous with readings automatically logged. Figures B2 (Figure 8-1, Cabrera 2018) and B3 (Figure 8-2, Cabrera 2018) present the results. As shown on the figures, the area between Column line 1 and Column Line 26 was divided into 30 smaller areas, for example the rooms along the south wall, or the area between two column lines. The number of measurements, maximum, minimum, mean and standard deviation was reported for each area. The background gamma count was approximately 6,100 counts per minute (cpm).
As reported on the figures, none of the areas had a mean count rate greater than 1.5 times background with the range of mean counts per minute between 6,094 cpm and 9,661 cpm. Only four area had mean count rats above 9,000 cpm. Bias volumetric concrete core samples were performed in those areas and did not indicate elevated activities (See Section 2.3). The slightly elevated the result may be from the proximate wall, or shine (Note - The raw data for these measurements is presented in Appendix I of the Cabrera 2018 report).
In addition, in April 2020, Arcadis performed gamma surveys of areas associated with the twenty-nine surface contamination samples (Figure B4). The counts were logged from a Ludlum 44-10 sodium iodine probe with a 2221 rate meter place adjacent to the surface contamination locations. The areal results ranged from 4,814 to 6,958 counts per minute (cpm) with a mean of 5,854 cpm. None of the areas had a count rate greater than 1.5 times background.
In summary, the gamma scan indicated no elevated areas for the scanned areas with the majority of the scanned areas at background levels.
2.2 Alpha Scan Results Concurrent with the gamma surveys, Cabrera also conduced alpha/beta measurements on the Building 6H floor surfaces as part of their overall supplemental radiological survey (Cabrera, 2018). The figures

discussed below are reproduced in Appendix A One-minute integrated alpha/beta scan measurements were performed on floor surfaces in Building 6H, Figures B5 (Figure 8-5, Cabrera 2018) and B6 (Figure 8-6, Cabrera 2018) of the report show the extensive coverage in the area between Column Lines 1 and 26.
As indicated by the color-coded circles on the figures, each representing an alpha/beta measurement, hundreds of measurements were taken. The color-coded results of the measurements indicated no measurement exceeded the surface contamination of less than 5,000 disintegrations per minute (dpm)/100 cm2 total alpha above background (NRC, 2006). Given the number of measurements and extensive coverage of the area, concrete waste from the Building 6H sub-surface foundation is not expected exceed the surface DCGLw. (Note - details of the survey are presented in Section 6.1 of the Cabrera 2018 report).
2.3 Concrete Core samples Tables B1 and B2 present the results of the radiological analyses of concrete core samples. The location of the samples is presented in Figure B7. Sample analysis was by alpha spectroscopy, gamma spectroscopy or both. The alpha spectroscopy samples were one-gram aliquots from the 300 to 500-gram samples required for gamma spectroscopy.
Table B1 presents the results of the December 2018 (nineteen samples) and the April 2019 (six samples) concrete core samples. The locations for the December 2018 sampling campaign were determined using MARRSIM guidance as discussed in the Cleanup Plan (Arcadis 2019). The April biased sampling locations focused on the southern area between Column Lines 12 and 16 in the areas that indicated elevated gamma activity in the 2018 Cabrera survey (See Section 2.1). A review of the data shows the following:
- 1. No sample had an isotopic concentration greater than 0.5 pCi/g of U-238 or U-234. This would indicate these are measurements of background uranium concentrations in the concrete or de-minimis concentrations of HEU.
- 2. The activity concentration results (pCi/g) from alpha spectroscopy samples for U-238 and U-234 are approximately equal indicting natural uranium rather than HEU.
- 3. Gamma spectroscopy results indicate Bi-214 and Pb-214 concentrations (pCi/g) approximately the same as the U-238 concentration indicating secular equilibrium in the U-238 chain reflecting natural uranium. U-238 / U-234 in HEU would not have these daughters in secular equilibrium.
- 4. U-235 results are U qualified or below detection limits for all alpha spectroscopy analyses, much below Highly Enriched Uranium (HEU) expectations.
- 5. The six bias samples only indicated natural uranium with the U-235 and U-238 concentration all less than 0.5 pCi/g.
Table B2 presents the results of the March 2020 sampling campaign which were available. Ten composite samples and 5 discrete samples have been analyzed. As indicated in Figure B7, the area between Column Lines 1 and 30 were divided in to 4 sections. Each section was divided into a north and south subarea. In each subarea (N4, N5, N6, N7, N8, S4, S5, S6, S7, and S8) six cores were collected and composited in one sample. In addition, discrete volumetric samples were collected along the center line of the building at columns 5, 10, 15, 20, and 25 (C5, C10, C15, C20, C25). A total of fifteen (15) concrete core samples were analyzed for radiological components using alpha and gamma spectroscopy. A review of the data to date indicates:
ADDENDUM TO MAY 2019 CLEANUP PLAN arcadis.com G:\\GE\\PRJ\\GE_UNC_New_Haven\\Reports\\Cleanup Plan\\Addendum\\UNC_Addendum to CUP_App B_Site Background Sampling Method Results_04.27.2020.docx 5
- 1. No sample had an isotopic concentration greater than 0.7 pCi/g of U-238 or U-234. This would indicate these are measurements of background uranium concentrations in the concrete or de-minimis concentrations of HEU.
- 2. The activity concentration results (pCi/g) from alpha spectroscopy samples for U-238 and U-234 are approximately equal indicting natural uranium rather than HEU.
- 3. The ratio of the activity concentration results (pCi/g) from alpha spectroscopy samples for U-238 and U-235 reflect a natural uranium ratio rather than HEU even with the large standard deviations.
The forty (40) samples of the concrete foundation in Building 6H indicates the concrete does not contain contamination greater than natural uranium beyond a depth that can be measured by the instrumentation used for the survey.
2.4 Concrete Surface Contamination The levels of fixed and removable surface contamination were analyzed for twenty-nine (29) locations on the Building 6H foundation. The locations surveyed were adjacent to the locations of the March 2020 concrete core samples. The location of the samples is presented in Figure B1.
Prior to sampling the surface was brushed to remove any loose debris and dirt from the surface of the concrete. The face of a Ludlum 43-89 alpha/beta detector with a Ludlum 2360 ratemeter was placed over the sample point and the alpha + beta counts recorded for 1 minute. The 2360 ratemeter also presents alpha and beta counts separately. Each observed alpha and beta count was adjusted to account for the 126 cm2 area, background, concrete self-absorption and detectors efficiency. The alpha and beta concrete self-absorption factors were 0.25 and 0.2968, respectively (MARLAP 2004). Since the face of the detector was 126 cm2, the adjusted counts were normalized to 100 cm2 by dividing each one minute count by 126.
After the probe was removed swipe samples, using dry, glass fiber filters (47 mm Whatman filters), were taken over the designated surface area. The filters per placed into protective envelopes and sent to vendor laboratory for alpha and beta analysis using a gas proportional counter.
Table B3 present the results of the radiological analyses of concrete smear samples. A review of the data indicates:
- 1. None of the counts exceeded the regulatory limit of 5,000 dpm alpha/100 cm2.
- 2. The total alpha contamination results ranged from 0 to 74 dpm alpha /100 cm2 with an average of 16 dpm alpha/100 cm2.These are essentially background total count rates.
- 3. The maximum alpha count rate was 74 dpm alpha/100 cm2 at location N4-SM-C25.Which is less than the maximum surface contamination is 15,000 dpm/100 cm2 alpha.
- 4. The remaining 28 fixed alpha sample count rates were all less than 2% of the limit (range 0 to 59 dpm/100 cm2).
- 5. None of the filter swipes exceeded the regulatory limit of 1000 dpm alpha/100 cm2 for removable contaminations. The removable alpha results ranged from 0 to 4 dpm alpha/100 cm2 with an average of 1 dpm alpha/100 cm2.
There results indicate the materials radioactivity is below release limits.

SUMMARY
OF NON-RADIATION ANALYTICAL RESULTS As part of the December 2018 building characterization investigation, four concrete floor slab samples were collected within Building 6H and submitted to and analyzed by Eurofins Test America Laboratory for Total PCBs by EPA Method 8082 and Total Inorganics by EPA Method 6010. Three of the four were also analyzed for Toxicity Characteristic Leachate Procedure (TCLP) for Volatile Organic Compounds (VOCs) by EPA Method 8260, Semi-Volatile Organic Compounds (SVOCs) by EPA Method 8270, and Inorganics by EPA Method 6010, and Mercury by EPA Method 7470.
During the month of March 2020, Arcadis collected a total of ten additional concrete floor slab samples over the Building 6H footprint. Sample locations are identified on Figure 1 and include subareas N4 through N8 and S4 through S8.Subareas N4 to N7and S4 to S7 are approximately 3,500 square feet (sf), and Areas N8 and S8 are approximately 2,900 sf. Arcadis collected a six-point composite sample from each subarea that was submitted to and analyzed by Pace National Laboratory for Total PCBs and Inorganics and TCLP VOCs, SVOCs, and Inorganics.
The analytical results from the December 2018 and March 2020 sampling events are collectively presented in Table B4. All results were either non-detect or well below regulatory levels.
