However, accounting for the uncertainty associated with the normalization factor, if calculated as the square root of the sum of squares of measured and calculated dose, respectively, would suggest a 63Ni specific activity concentration of —30 uCi/cc, and therefore in excess of the Class A limit (Part 61, Table 2). Please explain. In response to a licensee violation cited by an agreement state associated with measurement uncertainty, the U.S. Nuclear Regulatory Commission (NRC) 1 Anderson, Scott T.

Anderson CD18-0067 April 17, 2018 Page 2 of 15 clearly stated it inappropriate to require measurement uncertainty be included in demonstration of compliance with regulatory limits. 4 "The [NRC] Offices became aware of a letter transmitting a notice of violation that appeared to send an incorrect message to licensees. The incorrect message was that licensees must consider inherent uncertainties when measuring radiation levels approaching regulatory limits and must establish procedural limits that are less than the regulatory limits by an amount that equals (or exceeds) the 'instrument error.' That message is incorrect." "The NRC position is that the result of a valid measurement obtained by a method that provides a reasonable demonstration of compliance or of noncompliance should be accepted and that the uncertainty inherent in that measured value need not be considered in determining compliance or non-compliance with a regulatory limit. Thus, only the measured value (and not the sum of the measured value and its uncertainty) need be less than the value of the limit to demonstrate compliance with the limit. Conversely, only the measured value (and not the measured value less its uncertainty) need be greater than the value of the limit to demonstrate non-compliance with the limit."5 [emphasis added] In support of this directive, NRC further notes, "The methods of demonstrating compliance with [regulatory] limits are usually left to the regulated person. Any method which provides a reasonable demonstration of compliance will be accepted. In most cases, exact measured values are not required.

"7 The Division's request acknowledges as correct the referenced text report of the Ni-63 activity in the activated metal (projected at 88% of the Class A limit). However, the Division's direction to further account for uncertainty in demonstrating compliance with regulatory limits is contrary to its own practice, and inappropriate and divergent from NRC policy and guidance.8 2) The text further states (p.5), that the reactor vessel was characterized using several radiation surveys at multiple locations and that it is accepted practice by the NRC to apparently disregard upper tail uncertainties. It appears that if the upper tail uncertainty is used, 63Ni would be in excess of the Class A limit. Please explain and provide a reference. Please see the response provided to the Division's first request. The Division's suggestion that "if the upper tail uncertainty is used 63Ni would be in excess of the Class A limit" is contrary to its own practice and inappropriate and contrary to NRC policy.9 3) The text presents (p.7) a flow chart, depicting the NRC Branch Technical Position guidance overview as how to average single, discrete items. While the Division agrees that Section 3.3.1 of the NRC BTP is relevant for the concentration averaging characterization of the reactor, no mention is made, apart from three statements, of potential constraints as outlined in Section 3.3.4 of the BTP (see Figure 5 of the BTP, classification of encapsulated items, which should be followed.) If the intent is, however, to follow Section 3.8.4 of the BTP, the relevant information should be duplicated for the San Onofre reactor in an analog fashion. Section 3.3.4 of the BTP suggests application of volumetric and radiological constraints when utilizing BTP Section 3.3.1 concentration characterization for the SONGS RPV. However, since the SONGS RPV volume is greater than the container volume limit of 331 ft3 specified in Section 3.3.4 of the BTP for 7 Finerfrock, Dane L.

Anderson CD18-0067 April 17, 2018 Page 4 of 15 encapsulating waste, an alternative approach for satisfaction of the volumetric constraint is considered (in accordance with the alternative approaches for averaging guidance allowed in BTP Section 3.8). A) Site-Specific Intruder Assessments (BTP Section 3.8.1):10 Section 3.8.1 of the BTP suggests that regulatory information supporting a site-specific intruder assessment should include: • An overview of the proposed alternative approach (e.g., depth of burial or other factors) and how it will protect an inadvertent intruder. The SONGS RPV will be disposed in the Class A West embankment at an approximate depth of 40 feet below the top of the disposal embankment. Even though Class A LLRW is not required to be buried at this depth, it is well below the prescribed depth the NRC requires for other waste that is considered higher in radioactive concentration as Class C LLRW. Additionally, the SONGS RPV will be encased in controlled low-strength material (CLSM) which provides another barrier for intrusion. Protections provided with the Class A West embankment design (including depth of burial to large components and benefit of encasing the components in CLSM) from inadvertent intrusion into large components (including reactor pressure vessels) were approved by the Division with amendment 12 of Radioactive Material License UT2300249." "The disposal of debris and containerized waste in the large component area would continue unchanged with approval of the CAW Embankment LAR. Disposal of such waste involves construction of debris and containerized waste/Controlled Low Strength Material (CLSM) pyramids to minimize differential settlement within the embankment. Following acceptance and unloading, debris and/or large components are placed so as to minimize the volume of void spaces between containers/ components. Debris and large components are placed to minimize 10 U.S. Nuclear Regulatory Commission.

CLSM is a low-strength, flowable concrete. Standard concrete mixing and delivery equipment is used to pour CLSM in each debris pour. The flowability of the CLSM is controlled to ensure adequate filling of the voids within the oversized debris pour." "The disposal of debris and containerized waste for the proposed CAW Embankment is identical to that approved for the CAN embankment and the 2005 LRA (URS Corporation 2005a; 2005b). The conditions upon which the disposal is based are similar, except the overall height and surface area of the CAW Embankment are increased, thus increasing the volume of material potentially disposed of in the embankment. Analyses (Attachment 5 of Energysolutions 2011a; 2011b) demonstrate that the disposal of debris and containerized waste in the CAW embankment will perform at least as well as corresponding items approved for the Class A and CAN embankments (URS Corporation 2005a; 2005b) and reviewed for thepreviously proposed CAC embankment (AMEC 2005a; 2005b)." "Based on the information summarized above, the Division concludes that the Licensee's descriptions of the manner of placing debris and large components into the proposed CAW Embankment and CLSM use for backfill are acceptable."12[emphasis added] The Division further notes, "Utah and NRC regulations require an intruder barrier for the disposal of only Class C LLRW. Since only Class A waste will be disposed of in the proposed Disposal Embankment, no intruder barrier, as specifically defined by Utah regulations, is required. In a more general sense, however, intruder protection is required by the performance objective stated in URCR R313-25-20.

EnergySolutions' request included a projected Sum-Of-Fractions calculation demonstrating the vessel's current residual activity as being below the Class A limits promulgated in Utah Administrative Code (UAC) R313-15-1009 (which would decay to levels even lower at the regulatory-required 100-year time frame after which a member of the public may inadvertently intrude into the waste). Since the activity present in the 2006 grouted reactor pressure vessel was below the Class A limit and would be placed according to approved method, the Division deemed adequate the intruder protections. As the Division correctly notes in Request Ni-63 in the activated metal is the principle classification controlling nuclide at 88% of the class A limit. With a half-life of 100 years, its concentration at the earliest time an inadvertent intruder could gain access to the closed Class A West embankment (following a 100-year institutional control period) would be lower than 45% of the Class A limit. Therefore, the inadvertent intruder scenarios contemplated with the Class A West license amendment remain conservative and appropriate. 13 Ibid. p 36. 14 Rogers, Tye.

The outer package wall of the SONGS RPV consists of three inches of steel. The actual SONGS RPV is embedded in concrete and the steel wall of the RPV is eight inches thick. Concrete was used to secure the internal components in place to prevent shifting during transit. A detailed description of the SONGS RPV waste form has previously been provided to the Division,16,17,18,19 is consistent with the large components approved for placement in the Division's Class A West amendment to Radioactive Material License UT2300249,2° and is sufficiently similar to other historic large components with which the Division has previously provided classification and disposal concurrence.21'22 • An identification of the CA BTP's existing position for which an alternative is requested. This identification is herein made as the response to Request #3. The design of the package including multiple barriers to prevent intrusion (i.e., depth of burial, encased in CLSM, etc.) provide adequate assurance that any potential intrusion into the actual waste is extremely unlikely. Even in the event of intrusion, the retrieved material would be recognizable prior to the intruder drilling into the internals of the SONGS RPV. Therefore, the 16 WMG, 2018. 17 WMG.

Anderson CD18-0067 April 17, 2018 Page 8 of 15 regulatory information supporting a site-specific intruder assessment for the SONGS RPV is that already approved by the Division. B) Encapsulation of Discrete Items, Including Sealed Sources (BTP Section 3.8. 2):23 In Section 3.8.2 of the BTP, NRC recognizes that, "The position on encapsulation in Section 3.3.4 is considered generally suitable for all LLW disposal facilities licensed under 10 CFR Part 61 or the equivalent Agreement State regulation. Other provisions may be used on a specific basis for the encapsulation of items if—after an evaluation of the specific characteristics of the waste form, the disposal site, intrusion scenarios, and the method of disposal—there is reasonable assurance of compliance with the inadvertent intruder performance objective in 10 CFR 61.42." "As long as the proposed alternative provisions for an encapsulated item meet the 10 CFR 61.55 waste classification requirements, licensees do not need to seek authorization under 10 CFR 61.58 or request an exemption. "24 Therefore, encapsulation guidance in Section 3.3.4 of the BTP is considered suitable for the SONGS RPV under UAC R313-25, since the Division has already reviewed and approved the specific characteristics of the waste form (including the vessel's carbon steel, concrete, grout, and large component CLSM-entombment), the Clive Facility disposal site, the site and embankment's protections against inadvertent intrusion, and the depth and method of disposal. As such, Section 3.8.2 of the BTP supports a "... reasonable assurance of compliance with the inadvertent intruder performance objective in 10 CFR 61.42." 23 U.S. Nuclear Regulatory Commission.

Anderson CD18-0067 April 17, 2018 Page 9 of 15 C) Likelihood of Intrusion (BTP Section 3.8.3):25 In Section 3.8.3 of the BTP, NRC clarifies when considering likelihood of intrusion, "... [t] he staff continues to believe that these waste types might pose a unique hazard and that averaging constraints are appropriate. In developing averaging constraints for discrete items, the staff has used stylized carry-away scenarios.” Clearly, the grout already present within the SONGS RPV, its 8-inch thick outer steel shell, the minimum 4-feet of CLSM large component entombment, and then 40 feet of other waste and rock armor above the entombed large components reasonably minimize any inadvertent intruder "carry-away scenario" risk (as has already been demonstrated an Division approved with EnergySolutions' historic reactor pressure vessel and other large component placement). Therefore, the SONGS RPV is sufficiently similar to other large components for which Energysolutions has demonstrated that encapsulation is appropriate (according to the constraints included in Section 3.8 of the BTP). 4) The October 2002 Reactor Vessel and Internals Characterization Report WMG-20004-9088, Rev. 6 states that the RPV head and piping have been removed. The WMG-20004-9088 Report (Section 3.5.1) states that the RPV is low-allow carbon steel with a nominal wall thickness of 9.75 inches in the cylindrical region and 5.0 inches in the bottom head region. The Division assumes that the piping and head flange openings have been sealed. No mention of the cover material is made. Please provide a description of the materials used to secure these flanges, the material thickness and the method used to secure them. Also, the Division would like to see how these were accounted for in the evaluation for an inadvertent intruder scenario. WMG Response: The RPV primary coolant nozzles were cut flush with the exterior of the RPV wall and 4 inch A-36 steel cover plates were welded in place. It should be noted that the nozzle cover plates are contained within the canister lower assembly shell. The 3 inch thick ASTM A572 Gr42 steel upper canister closure plate was attached to the RPV flange using six rigging studs.

The upper canister closure plate was then welded to the canister lower assembly using a full penetration weld.26 Refer to EnergySolutions' response to question #3 for a discussion on the inadvertent intruder scenario. 5) The October 2002 Reactor Vessel and Internals Characterization Report WMG-20004-9088, Rev. 6, Table 5-1, shows a volume of 1,333 ft3 and a weight of 658,695 lbs. The January 2018 Reactor Pressure Vessel Package Characterization Table 1, shows a volume of 5.48e3 ft3 and a weight of 9.43e5 lbs. This is a difference of 4,147 ft3 and 284,305 lbs. Please account for these disparities. WMG Response: The results from WMG-20004-9088 Rev. 6 did not include the weight of the cementitious grout in the package. The additional weight and volume account for the grout which is consistent with the regulatory guidance for encapsulation.27 6) The October 2002 Reactor Vessel and Internals Characterization Report WMG-20004-9088, Rev. 6, Table 5-1, shows a package activity of 1.14e4 curies for 63Ni. The January 2018 Reactor Pressure Vessel Package Characterization Table 1 and the table shown in Updated Classification Status Report, 17-230-RD-218, July 2017 shows a package activity of 4.79e3 curies for 63Ni. It is noted in the Updated Classification Status Report, 17- 230-RE-218, July 2017, that the characterization results were "decay corrected to the earliest anticipated shipping date of December 1, 2018.” However, 63Ni activity would have decayed to 1.0186e4 curies in the period between October 2002 and December, 2018. Please account for this discrepancy. WMG Response: The RPV characterization results reported in WMG-20004- 9088 were based on the original neutron transport and activation analysis. Initial dose rate measurements were conservatively taken inside the RPV and were used to normalize the activation analysis. This resulted in a high activity estimate, since the dose rate measurements were biased high with shine from other components within the RPV. 26 Tuite, 2018. 27 Tuite, 2018. 299 South Main Street, Suite 1700 • Salt Lake City, Utah 84111 (801) 649-2000 • Fax: (801) 880-2879 • www.energysohnions.com .0....................... ENERGYSOLUTIONS Mr. Scott T. Anderson CD18-0067 April 17, 2018 Page 11 of 15 In December of 2001, detailed radiation surveys were obtained on components which were removed from the reactor vessel and surveyed in an area with low background radiation. These radiation survey results represent the best available empirical information to benchmark or calibrate the activation analysis results. The components were modelled using point kernel shielding techniques and the calculated radiation dose rates were more than a factor of 2 higher than the actual radiation levels on the components. Therefore, the activation analysis results were normalized in a revised analysis performed in February of 2008 thereby reducing the activity by a factor of 2.121 which was the ratio of the modelled dose rate to the actual measured dose rate. This yielded a calculated Ni-63 activity of 4.79E+03 as of the reference date.28 7) The January 8, 2018 San Onofre Unit 1 Reactor Pressure Vessel Package Characterization report states, "... a waste is not considered a RCRA characteristic waste if the TCLP lead result is 4.5 mg/L. TCLP with an uncertainty value of 1.0 mg/L." Please provide a reference for this statement. Based on the uncertainty of 1.0 mg/L in your example, it would be considered a characteristic waste in Utah. Please see Response #1 with respect to the NRC statement regarding measurement uncertainty.29 8) Utah Code 19-3-102(8)(a) states: "high-level nuclear waste" means spent reactor fuel assemblies, dismantled nuclear reactor components, and solid and liquid wastes from fuel reprocessing and defense-related wastes." Please clarify how the SONGS Unit 1 RPV does not fit the description of "dismantled nuclear reactor components." In 1946, Congress established the United States Atomic Energy Commission (AEC) to regulate the peacetime development of atomic science and technology.3° The AEC was subsequently abolished in 1974 and succeeded by the U.S. Nuclear Regulatory Commission (NRC) and the Energy Research and Development Administration (now part of the U.S. Department of Energy).31 The Nuclear Waste Policy Act of 1982 placed sole responsibility for oversight of the Country's high-level nuclear waste and spent fuel with the Federal Government. 28 Tuite, 2018. 29 Hickley, 1990. 30 Sect. 1(a), Atomic Energy Act of 1946 (Public Law 585) 78th Cong. 1st sess. 31 Sect. 5801, Energy Reorganization Act of 1974 (Public Law 93-438) 106th Cong. 299 South Main Street, Suite 1700 • Salt Lake City, Utah 84111 (801) 649-2000 • Fax: (801) 880-2879 • www.energysolutions.com ENERGY SOLUTIONS Mr. Scott T. Anderson CD18-0067 April 17, 2018 Page 12 of 15 Requirements of this Act are reflected in 42 U.S. Code § 10131(a)(4), which states "The Congress finds that—(4) ... the Federal Government has the responsibility to provide for the permanent disposal of high-level radioactive waste and such spent nuclear fuel as may be disposed of in order to protect the public health and safety and the environment, the costs of such disposal should be the responsibility of the generators and owners of such waste and spent fuel;" 42 U.S. Code § 10101(12) defines high-level nuclear waste to mean, "the highly radioactive material resulting from the reprocessing of spent nuclear fuel, including liquid waste produced directly in reprocessing and any solid material derived from such liquid waste that contains fission products in sufficient concentrations; and (B) other highly radioactive material that the Commission, consistent with existing law, determines by rule requires permanent isolation." 42 U.S. Code § 10101(12) further defines "spent nuclear fuel" to mean, 'ficel that has been withdrawn from a nuclear reactor following irradiation, the constituent elements of which have not been separated by reprocessing." These definitions do not include any reference to "dismantled nuclear reactor components" such as reactor pressure vessels or reactor heads but rather are specific to the actual spent nuclear fuel used in the reactor core. Energysolutions is not aware of the basis of the Utah Code 19-3-102(8)(a) defmition for "high- level nuclear waste" but can only assume given the federal defmition and regulatory jurisdiction over high-level waste that "dismantled nuclear reactor components" implies components that are directly in contact with the spent nuclear fuel such as fuel rods made up of zirconium metal tubes and associated fuel assemblies. As discussed below, the regulation of high-level waste is solely the responsibility of the Federal Government, not individual states. The Low-Level Radioactive Waste Policy Amendments Act of 1985 placed responsibility with States for the disposal of low-level radioactive waste that has 299 South Main Street, Suite 1700 • Salt Lake City, Utah 84111 (801) 649-2000 • Fax: (801) 880-2879 • www.energysolutions.com ENERGYSOLUTIONS Mr. Scott T. Anderson CD18-0067 April 17, 2018 Page 13 of 15 been generated within their borders.32 In support of the 1985 Act, 42 U.S. Code § 10101(16) specifically excludes high-level nuclear waste in its definition of low- level radioactive waste, "radioactive material that—(A) is not high-level radioactive waste, spent nuclear fuel, transuranic waste, or by-product material as defined in section 2014(e)(2) of this title; and (B) the Commission, consistent with existing law, classifies as low-level radioactive waste. "[emphasis added] Furthermore, the 1985 Act limits the transfer of authority to States that have entered into Agreements with the NRC under section 274 of the 1946 Atomic Energy Act to "regulate the disposal of low-level radioactive waste under such agreement" [42 U.S. Code § 2021b(1)(B)]. On March 29, 1984, NRC entered into such an agreement transferring stewardship for the regulatory oversight of low-level radioactive waste and 1le.(2) by-product material to the State of Utah.33 In accordance with its NRC Agreement, the State of Utah has licensed EnergySolutions to manage Class A low-level radioactive waste (via Radioactive Material License UT2300249) and 1le.(2) by-product material (via Radioactive Material License UT2300478). Since it is contrary to the 1982 Act and not allowable by the 1985 Act, the NRC Agreement did not transfer any authority nor further empower the State of Utah to oversee management of high-level nuclear waste. In making this and similar agreements, Title 42 of U.S. Code § 2021(c), notes that "No agreement entered into pursuant to subsection (b) shall provide for discontinuance of any authority and the Commission shall retain authority and responsibility with respect to regulation of—(4) the disposal of such other byproduct, source, or special nuclear material as the Commission determines by regulation or order should, because of the hazards or potential hazards thereof not be so disposed of without a license from the Commission." 32 Low-Level Radioactive Waste Policy Act of 1985, As Amended (Public Law 99-240) 112th Cong. 2nd sess. 33 U.S. Nuclear Regulatory Commission.

Anderson CD18-0067 April 17, 2018 Page 14 of 15 Consequently, authority to regulate the management and disposal of high-level nuclear waste solely resides squarely with federal agencies. As such, the State of Utah does not possess authority to promulgate nor act on any high-level nuclear waste definition promulgated in Utah Code § 19-3-102(8)(a). Furthermore, any action taken on such a definition is contrary to the limitations and conditions of its 1984 low-level radioactive waste oversight Agreement with NRC. In addition, EnergySolutions has historically coordinated closely with the State of Utah for receipt, management and disposal of large components (including reactor pressure vessels) characterized as Class A low-level radioactive waste. For example, in 2002, EnergySolutions (known then as Envirocare of Utah) and the State of Utah exchanged correspondence on the appropriate physical characteristics of sand saddles to be placed beneath the reactor head of the SONGS RPV.34 Similarly, the Division offered concurrence in 2006 with EnergySolutions' similar application of BTP guidance for classification of a reactor vessel component from a different generator, noting "For activated metal components, the [Division] interprets the BTP as that classification may be based on the radionuclide concentrations averaged over the [reactor vessel] component ..."35 After authorizing such for decades, electing now to arbitrarily alter the State's historic approval of its disposal of large reactor components (including reactor pressure vessels), that have been classified by NRC as Class A low-level radioactive waste, significantly challenges EnergySolutions' ability to remain competitive in the Class A waste disposal market. EnergySolutions has properly received a license for management of Class A low-level radioactive waste from the NRC and the State of Utah, and has been disposing of Class A waste, including large components and reactor pressure vessels, pursuant to these authorizations for decades. If the Division now takes the position that the State's imprecise definition of high-level nuclear waste prohibits further disposal of large Class A low-level radioactive waste reactor components, it deprives EnergySolutions of an economically viable use of its licensed land without proper administrative procedure and contrary to legal precedence.36 34 Shrum, 2002. 35 Finerfrock, 2006. 36 Lucas v. S.C.

Anderson CD18-0067 April 17, 2018 Page 15 of 15 Therefore, the State of Utah does not inherently possess nor has it been granted any regulatory authority to redefine or otherwise regulate high-level nuclear waste. Similarly, the Division has granted licenses, renewed licenses and otherwise closely coordinated with EnergySolutions in management of large reactor components similar to the SONGS RPV (characterized as Class A low- level radioactive waste, not high level nuclear waste). Subjectively prohibiting disposal of the SONGS RPV because of the inaccurate and unauthorized definition in Utah Code § 19-3-102(8)(a) is contrary to longstanding Division- accepted practice, the regulatory authority of the Division, the federal definition of high-level nuclear waste, and contrary to legal precedence. EnergySolutions appreciates the Division's willingness to continue its long-standing practice of providing concurrence regarding application of the BTP to the classification of large reactor components. If these responses resolve its concerns, EnergySolutions herein requests the Division's written concurrence with said application of the NRC Branch Technical Position on Concentration Averaging and Encapsulation and that the SONGS RPV can be disposed at Clive as Class A low-level radioactive waste (subject to the accuracy of the generator's final characterization and classification — as directed by the NRC).3 Should there be any questions regarding these responses or this Request, please contact me at 801-649-2000.
