# 1.0 EXECUTIVE SUMMARY

**In accordance with 40 CFR 194.8(b), the U.S. Enviro nmental Protection Agency (EPA or the** 

**Agency) conducted Baseline Inspection No. EPA-INL-C CP-05.05-8 of the Central** 

**Characterization Project (CCP), located at the Idah o National Laboratory (INL) from May 3-5,** 

**2005. As a result of this baseline inspection, EPA approved the INL-CCP waste characterization** 

**(WC) program with conditions and limitations as doc umented in the INL Baseline Final** 

**Inspection Report (see EPA Docket No. A-98-49; II-A 4-59). This baseline approval specified** 

**four nondestructive assay (NDA) systems. INL-CCP re cently requested EPA approval of a Tier** 

**1 (T1) change at INL in the form of the addition of the Super High Efficiency Neutron Counter** 

**(SuperHENC) for assaying two types of waste containe rs. Based on EPA’s evaluation detailed** 

**in this report, EPA approves the SuperHENC for assa ying contact-handled (CH) transuranic** 

**(TRU) wastes in the following configurations:**

• **Standard Waste Boxes (SWBs) containing four 55-gall on drums of retrievably-stored** 

**S3000 sludge waste**

• **100-gallon overpacks containing compacted 55-gallon drums (pucks) of newly** 

**generated S5000 debris waste**

• **SWBs containing 100-gallon drums, each of which con tain compacted 55-gallon drums** 

**(pucks) of newly-generated S5000 debris waste**

**This report serves as EPA’s evaluation of the Super HENC for CH TRU wastes at INL-CCP as a** 

**T1 change. Using the information provided in this report, EPA has determined that the** 

**SuperHENC is adequate for characterization of CH TRU waste. This approval does not make** 

**any changes to the tiering table provided with the baseline approval. Changes to the approved** 

**components of the SuperHENC system at INL-CCP, must follow the tiering requirements** 

**described in the baseline inspection report issued for the INL-CCP CH program (Docket no. A** 

**98-49; II-A4-59, Dated November 1, 2005).**

2.0 PURPOSE OF INSPECTIONS

**Any changes to the WC activities from the date of t he baseline inspection must be reported to,** 

**and, if applicable, approved by EPA, according to t he tiering requirements set forth in the INL** 

**CCP Baseline Final Report cited above.**

**Under the changes to 40 CFR 194.8 promulgated in th e July 16, 2004,**  Federal Register **notice,**

**EPA must perform a single baseline inspection of a TRU waste generator site’s WC program.** 

**The purpose of the baseline inspection is to approv e the site’s WC program based on the** 

**demonstration that the program’s components, with a pplicable conditions and limitations, can** 

**adequately characterize TRU wastes and comply with the regulatory requirements imposed on** 

**TRU wastes destined for disposal at the WIPP. An E PA inspection team conducts an onsite** 

**inspection to verify that the site’s system of cont rols is technically adequate and properly** 

**implemented.**

# 2



# Following EPA’s approval of WC processes evaluated **during the baseline inspection, EPA is**

**authorized to evaluate and approve, if necessary, c hanges to the site’s approved WC program by** 

**conducting additional inspections under the authori ty of 40 CFR 194.24(h). Under 40 CFR** 

**194.24, EPA has the authority to conduct continued compliance inspections to verify that the site** 

**continues to use only the approved WC processes to characterize the waste and remains in** 

**compliance with all the regulatory requirements. B ased on the adequacies of the WC processes** 

**demonstrated during the baseline inspection, includ ing all conditions and limitations, EPA** 

**specified which subsequent WC program changes or mo difications must undergo further EPA** 

**approval under 40 CFR 194.24. This was accomplishe d by assigning a tier level to each aspect** 

**of the CCP’s characterization program. T1 activiti es have more stringent reporting requirements** 

**and require that DOE notify EPA, and that EPA provi de approval prior to implementation. The** 

**rule under which baseline inspections are conducted can be found in the**  Federal Register **(Vol.**

**69, No.136, pages 42571–42583 of July 16, 2004).**

3.0 PURPOSE OF THIS REPORT

**This report presents the results of the EPA’s evalu ation of a T1 change of the implementation of** 

**the SuperHENC NDA system for assaying CH TRU wastes by INL-CCP. This inspection report** 

**documents the basis for EPA’s approval decision and explains the results of the technical** 

**evaluation of the SuperHENC at INL-CCP.**

**EPA’s final approval decision regarding the SuperHE NC located at INL-CCP has been conveyed** 

**to DOE separately by letter. EPA will also announc e the decision on its website at** 

**www.epa.gov/radiation/WIPP , in accordance with 40 CFR 194.8(b)(3).** 

4.0 SCOPE OF REVIEW

**The scope of this evaluation was the operation of t he SuperHENC NDA system located at INL** 

**CCP. The SuperHENC was evaluated with respect to it s ability to identify and quantify the** 

**activities of the 10 WIPP-tracked radionuclides, lo wer limit of detection (LLD), Total** 

**Measurement Uncertainty (TMU), and other related te chnical aspects including the performance** 

**of replicate analyses of containers and the statist ical evaluation of those replicates as described in** 

**Section 6 of this report.**

5.0 EVALUATION TEAM

**All personnel involved in the SuperHENC evaluation a re listed in Table 1 along with each** 

**person’s affiliation and function for the purpose o f this inspection. For logistical reasons, Patrick** 

**Kelly and Alan Simpson did not participate in the o n-site evaluation at INL, but did participate in** 

**the subsequent teleconference.**

# 6.0 EVALUATION OF THE CCP SUPERHENC

**EPA inspected one SuperHENC NDA system that will be u sed to characterize CH TRU wastes** 

**at INL-CCP. The inspection occurred in two parts: (1) an onsite evaluation of the SuperHENC** 

**system and associated records and personnel at INL on January 23 – 24, 2007; and (2) a** 

**teleconference on January 31, 2007, during which ad ditional details were provided and the** 

**system’s operational aspects were discussed. As pa rt of the inspection, EPA reviewed the** 

**following elements of the SuperHENC process:**

• **Capability of the measurement hardware and software to perform the required analyses** 

• **Technical adequacy of the NDA documents and procedur es** 

• **Knowledge and understanding of the personnel involv ed in the NDA program** 

**Attachment A identifies the objective evidence that was examined for EPA’s evaluation. The** 

**following documents were among those examined to as sess the INL-CCP SuperHENC:**

**During the inspection, the EPA inspection team memb ers assessed several technical elements of** 

**the SuperHENC system that are detailed in Attachmen t A and are discussed below.** 

**(1) The design and operational history of the Supe rHENC was assessed.** 

**The SuperHENC system is located in a trailer on site at INL in the Radioactive Waste** 

**Management Complex (RWMC) adjacent to the Stored Wa ste Examination Pilot Plant** 

**(SWEPP), a building that houses other INL-CCP NDA sy stems used for characterizing TRU** 

**wastes. The SuperHENC was originally operational a t the DOE’s Rocky Flats Environmental** 

**Technology Site (RFETS) in Golden, Colorado, where the site used this equipment to assay CH** 

**TRU wastes from 2001 until the site’s closure in 20 06. At RFETS, this system was used to assay** 

**CH TRU wastes in SWBs 1**  

# and 55-gallon (208-liter) drums; it was also used **for nuclear material**

**accountability and criticality safety compliance. At INL, this system will assay SWBs as well as** 

**100-gallon overpacks containing compacted 55-gallon drums referred to as**  pucks **. Pucks are**

**produced at a super compaction facility operated by the Advanced Mixed Waste Treatment** 

**Project (AMWTP) co-located in the RWMC at INL and a re provided to INL-CCP post** 

**compaction. The three possible assay configuration s for the SuperHENC are as follows:** 

• **SWBs containing four 55-gallon drums of retrievably -stored S3000 sludge waste** 

• **100-gallon overpacks containing compacted 55-gallon drums (pucks) of newly** 

**generated S5000 debris waste**

• **SWBs containing two 100-gallon drums, each of which contains compacted 55-gallon** 

**drums (pucks) of newly-generated S5000 debris waste**

**.**

**The materials the system will assay fall into two c ategories: S5000 debris which will have been** 

**loaded into 55-gallon drums and compacted into puck s by AMWTP that are overpacked in** 

**100-gallon drums; or S3000 sludge (solids) which wi ll be packaged in 55-gallon drums and will** 

**not be compacted.**

**This system consists of a passive neutron counter a nd an integral gamma-ray spectrometer, the** 

**SuperHENC Gamma Energy Analysis System (SGEAS). The passive neutron counter uses 240** 

**3** 

# He proportional counters in a 4- Β **geometry and an external 252**  

# Cf source for the Add-a-Source

**(AAS) matrix correction function and an ANTEC advanc ed multiplicity shift register. The** 

**neutron component determines the mass of spontaneou sly fissioning material in waste** 

**containers, referred to as the 240**  

# Pu **Effective** 

# ( **240** 

# Pu **Eff** 

# ). The **240** 

# Pu **Eff** 

# is defined as the amount of **240** 

# Pu

**that would produce the observed true coincidence ra te, after correcting for the neutron**

# A Standard Waste Box or SWB is a rectangular conta **iner with somewhat rounded corners whose**

**measurements are approximately 54.5 inches wide by 37 inches high by 71 inches long. The cavity will**  **accept**

**containers up to 59 inches wide by 59 inches high b y 91.5 inches long.**

# moderation properties of the waste matrix. The sys **tem’s calibration was based on measurements**

**of a non-interfering matrix and it includes a curve that relates the measured doubles rate for each** 

**container with the 240**  

# Pu **Eff** 

# , as documented in BII-5221-CVR-001. Note that a de **velopment of an**

**AAS correction factor is necessary to convert the o bserved doubles rate (with the sample matrix)** 

**to the equivalent calibration doubles rate (no matr ix). The AAS correction curve is sufficiently** 

**robust to enable corrections over a wide range of m aterials or matrices. The SuperHENC is** 

**operated by a custom-tailored version of the Los Al amos National Laboratory (LANL) Neutron** 

**Coincidence Counting (NCC) software that controls d ata collection and analysis, AAS** 

**movements and all calibration and exception handlin g functions.** 

**The SGEAS consists of a single high-purity germaniu m (HPGe) detector that functions in two** 

**modes: relative ratio mode, where isotopic ratios are determined using the PCFRAM**  **2** 

# isotopic

**code; and absolute mode, where the absolute quantit ies of specific radionuclides are determined** 

**based on analyzing gamma spectra. INL-CCP personne l stated that only the relative ratio mode** 

**will be used and that radionuclides will not be qua ntified on the basis of photon (gamma)** 

**emission only. Due to the levels of 241**  

# Am and its intense 59 keV photons anticipated in th **e**

**SuperHENC samples, the HPGe is fitted with a fixed 1 .09 mm cadmium/polyethylene filter that** 

**effectively removes photons below approximately 80 keV. There is an additional 10 mm steel** 

**filter that may be used for containers where 241**  

# Am concentrations are such that assay dead-time

**exceeds 25%. Each HPGe measurement consists of one 450-second count, following which the** 

**waste container is rotated 180** ° **and a second 450-second count HPGe is initiated. T he reported** 

**gamma results consist of the composite of both 450- second counts.** 

**The combination of neutron and isotopic distributio n information allows quantification of**  **238**

**BII’s Efficiency Times Attenuation (ETA) calculatio ns in an approach that has been evaluated** 

**previously on several BII NDA systems at other TRU W C facilities. Each waste container’s**  **234** 

# U

**content is performed by application of scaling fact ors that are based on observed values for**  **235** 

# U

**and 238**  

# U. The determination of **90** 

# Sr is performed by application of a scaling factor **based on**

**137** 

# Cs. The CTAC Technical Specialist identified one d **ocumentation issue related to the use of**

**radionuclide scaling factors. Procedure CCP-TP-148 , Appendix 1, indicates that the scaling** 

**factors used to quantify 234**  

# U and **90** 

# Sr are obtained from AK and are specified by memora **ndum.**

**However, these scaling factors were derived from re port LA-UR-00-2584, and this discrepancy** 

**was noted in CBFO Corrective Action Report (CAR) No. 07-006.** 

**There are no EPA technical concerns regarding the d esign and ability of the SuperHENC to** 

**quantify the 10 WIPP-tracked radionculides.**

**(2) The passive neutron and gamma calibrations of the SuperHENC had been performed as**

# This is the calibration of record for the INL-CCP S **uperHENC. This calibration was confirmed**

**at INL in 2006, and is documented in BII-5221-CVR-0 01,**  Calibration and Validation Report

SuperHENC Mobile Assay System, **Revision 0, November 2006. Calibration confirmatio n was** 

**performed with six measurements of an empty SBW ove r a range of Pu loadings from 0.913 to** 

**12.658 g 240**  

# Pu **Eff**



# (15.035 to 203.616 g Pu Total). The acceptance c **riteria for accuracy (Percent**

**Recovery) and precision (Percent Relative Standard Deviation) were met for each of the six runs.** 

**The calibration itself is matrix independent, and a dditional testing will be performed in the future** 

**through the Weekly Interfering Matrix Checks that a re required in DOE-WIPP-02-3122. The** 

**system’s stated operational ranges for neutron assa ys are from the Limit of Detection or LLD** 

**(discussed below) to 12.658 g 240**  

# Pu **Eff** 

# , equivalent to 203.616 g weapons grade (WG) Pu as **stated**

**in BII-5221-CVR-001. These values conflicted with values for the system’s operational range** 

**found in CCP-TP-146 and CCP-TP-170. INL-CCP person nel acknowledged this discrepancy** 

**and committed to changing the two procedures to agr ee with BII-5221-CVR-001. This was** 

**acceptable. The energy versus channel calibration for the HPGe was performed using three** 

**photon lines from 152**  

# Eu at 121.8, 344.8 and 778.9 keV. This relationshi **p is checked daily to**

**ensure that the 344.8 keV peak’s centroid and Full- Width-a-Half-Maximum (FWHM) are within** 

**predetermined criteria shown in BII-5221-CVR-001, T able 2. Because the HPGe is used in** 

**relative ratio mode only, there is no true gamma op erational range, although between 1 and 5 g** 

**of WG Pu are needed to successfully execute FRAM, d epending on the matrix.** 

**Regarding matrix checks, INL-CCP stated that the SW B matrix surrogates that were used** 

**previously at RFETS were independently evaluated fo r the purpose of using them for the** 

**SuperHENC at INL-CCP. These efforts are documented in WTS CCP INL SWB Summary** 

**Report WIPP1-406914, Idaho National Laboratory Centr al Characterization Facility Standard** 

**Waste Box Matrix Surrogate Inspection Summary Repor t dated September 18, 2006. This is a** 

**reasonable approach to procuring additional matrix standards suitable for the SuperHENC. At** 

**this time there was no plan to obtain standards for the 100-gallon geometry.** 

**There are no technical concerns regarding the passi ve neutron and gamma calibrations of the** 

**SuperHENC.**

**(3) The TMU of assays performed on the SuperHENC h ad been determined and documented.** 

**The determination of the TMU for the SuperHENC is d ocumented in BII-5221-CVR-001,** 

**Section 4.1.1. This section addresses the effects on the passive neutron assay of the** 

**contributions from source position, calibration unc ertainty and counting statistics, background,** 

**self-shielding, systematic end and spatial effects, neutron multiplication, and isotopics. For the** 

**HPGe, the TMU evaluation was minimal because the sy stem will not be used to generate** 

**quantitative gamma data. There are no technical co ncerns regarding the determination and** 

**documentation of the SuperHENC’s TMU.**

**(4) The LLD, including the minimum detectable conc entration (MDC) of the SuperHENC had** 

**been determined and documented.**

**The LLD was defined in CCP-PO-002, “CCP Transuranic Waste Certification Plan,” as:** 

# 7



# That level of radioactivity which, if present, yiel **ds a measured value greater than**

**the critical level with a 95% probability, where th e critical level is defined as that** 

**value which measurements of the background will exc eed with 5% probability.** 

**In order to be able to discriminate TRU and non-TRU wastes, a NDA system must have an LLD** 

**less than 100 nCi of TRU alpha activity per gram (n Ci/g) of waste. The LLD of any given NDA** 

**measurement depends on the type of measurement (pas sive neutron or gamma), the properties of** 

**the waste matrix being assayed, the data acquisitio n (measurement) time, and the environmental** 

**background. For this reason, the LLD is expected t o vary from drum to drum and also may vary** 

**between measurements of the same drum. A neutron-b ased**  **240** 

# Pu **Eff** 

# LLD was determined using

**eight measurements of a full SWB containing surroga te matrices (combustibles and metals)** 

**without any added Pu sources. The results of these assays were used to generate the matrix** 

**related and background-dependent terms that were in corporated in the Neutron Gamma** 

**Interrogation (NGI) software. NGI makes a determinat ion of the LLD for each assay based on** 

**the sample’s measured net matrix mass using the mat rix specific parameters that are stored in a** 

**NGI parameter file. BII-5221-CVR-001, Table 20 prov ides values for the neutron-based LLDs** 

**for a variety of net matrix masses from** empty **(0 kg) to v** ery light **(161.2 kg) to** heavy **(1925.7 kg)**

**over a range of three 240**  

# Pu contents, WG (6% **240** 

# Pu), 12% **240** 

# Pu and 18% **240** 

# Pu. The limiting

**case of a v** ery light

**matrix and Pu provides an LLD of 100 nCi/g and the heavier matrices and** 

**higher 240**  

# Pu contents provide LLD values less than 100 nCi/g.

**The SuperHENC uses** LLD equivalents **for 241**  

# Am, **238** 

# Pu, **239** 

# Pu, **240** 

# Pu, **241** 

# Pu and **242** 

# Pu because

**these are not determined directly by the SuperHENC.** LLD equivalents **are also used for 235**  

# U,

**238** 

# U and **137** 

# Cs because INL AK does not provide useable isotopic **values for these radionuclides.**

**These are called** LLD equivalents **because an absolute LLD is not determined for each of these** 

**radionuclides but instead is derived by applying ea ch radionuclide’s mass fraction relative to** 

**240** 

# Pu **Eff** 

# (isotopic contribution) to the **240** 

# Pu **Eff** 

# neutron-based LLD. These values are summarized

**in BII-5221-CVR-001, Table 21. Only measured value s that exceeded the reported LLD for that** 

**measurement were to be reported and were used in ca lculations of derived quantities, such as** 

**total TRU alpha activity and TRU alpha activity con centration.** 

**There are no technical concerns regarding the techn ical derivation and application of LLDs and** 

**LLD equivalents relative to the SuperHENC.**

**(5) EPA replicate testing of the SuperHENC was per formed and evaluated.** 

**The purpose of the replicate testing performed as p art of this inspection is to provide EPA with** 

**an independent means to verify that the SuperHENC ca n provide consistent, reproducible results** 

**for the determination of the quantity of 10 WIPP-tr acked radionuclides (**  **241** 

# Am, **137** 

# Cs, **238** 

# Pu,

**239** 

# Pu, **240** 

# Pu, **242** 

# Pu, **90** 

# Sr, **233** 

# U, **234** 

# U and **238** 

# U) and the TRU alpha concentration. This is normal **ly**

**accomplished by requesting that the site reassay dr ums that were previously characterized on the** 

**same system or instrument in order to demonstrate t he following:** 

• **The instrument produces results consistent with the reported TMU by comparing the** 

**sample standard deviation for a number of replicate measurements taken over several** 

**hours or days to the reported TMU.**

# 8



# • **The instrument provides reproducible results over l onger periods of time, such as weeks** 

**or months, by comparing the results of the replicat e measurement(s) to the original** 

**reported values.**

**EPA requested that INL-CCP reassay two waste contai ners that EPA randomly selected from a** 

**list of containers previously assayed on the SuperH ENC. Due to the system’s short operational** 

**history, the list of potential candidates for repli cate assays was small and the time between the** 

**original measurement and the five replicates was sh ort. The following containers were chosen:** 

• **One 100-gallon drum containing S5000 debris, Contai ner No. BN10139128** 

• **One SWB containing S3000 sludge (solid), Container No. BN10141587** 

**At EPA’s request, each of these previously assayed drums was reassayed five times on the** 

**SuperHENC for this inspection. Two statistical test s, a chi squared (χ**  **2** 

# ) test and a t **test, were**

**performed on the replicate analyses of each contain er. Analytical data for each assay event and** 

**results of the statistical analysis are included in Attachments B.1 through B.4.** 

**For the 100-gallon drum Container No. BN10139128 the** t **test showed no statistically significant**

**differences between the original measurement assay values and the average of the five replicate** 

**measurements for all measurement parameters. The χ 2**  

# test for this same container showed that

**the observed variances in the replicate measurement s were less than or equal to the reported** 

**uncertainties for all values within the statistical limits of the test. There are no outstanding issu**  **es**

**with either statistical test for this container.**

**For SWB Container No. BN10141587 the** t **test showed a** highly significant **flag for the**

**difference between the original measurement assay v alues and the average of the five replicate** 

**measurements for 238**  

# Pu and **242** 

# Pu. This is probably attributable to the fact that **the original**

**measurements used isotopic information (mass fracti ons) from the SGEAS FRAM analysis,** 

**while for each of the five replicate assays, the FR AM analysis failed to produce reportable** 

**isotopics within the required uncertainty, i.e., th ey were not usable. The original FRAM-based**

# 7.1 Conclusions

**During this T1 evaluation, EPA evaluated the perfor mance of the INL-CCP SuperHENC. Based** 

**on the results of this evaluation, EPA is approving the INL-CCP SuperHENC NDA system for** 

**assaying retrievably-stored and/or newly-generated wastes in the following configurations:** 

• **Standard Waste Boxes (SWBs) containing four 55-gall on drums of retrievably-stored** 

**S3000 sludge waste**

• **100-gallon overpacks containing compacted 55-gallon drums (pucks) of newly** 

**generated S5000 debris waste**

• **SWBs containing 100-gallon drums, each of which con tain compacted 55-gallon drums** 

**(pucks) of newly-generated S5000 debris waste**

**This approval does not make any changes to the tier ing table provided with the baseline** 

**approval. Changes to the approved components of th e SuperHENC system at INL-CCP, must** 

**follow the tiering requirements described in the ba seline inspection report issued for the INL** 

**CCP CH program (Docket no. A-98-49; II-A4-59, Dated November 1, 2005).**
