II SUMMARY 8. Designed and constructed by Combustion Engineering (CE), the Palisades nuclear power plant, which began operation in 1971, is one of the oldest reactors in the United States. According to the Westinghouse analysis1, of the neutrons impinging upon the walls of the Palisades reactor, there must be no more than a 1 sigma (20%) variance between the analytical calculations and the physical capsule samples that are sometimes called coupons, are located within the reactor itself, and 1 The Westinghouse Analysis is discussed in detail in the Significant Analytical Problems Section of this Declaration.

Page 3 of 23 that are made of the same metal as the reactor vessel welds. Without pulling another embrittlement coupon from within the reactor, there can be no assurance that the serious embrittlement is not still occurring and outside the 1 sigma bounds required by the Westinghouse analysis. The current analysis cannot be substantiated because physical data is lacking to support any mathematical analysis. The last physical capsule coupon sample was withdrawn from within the reactor and analyzed more than 10 years ago. The reactor vessel at Palisades is the most important safety barrier to protect the public in the case of a design basis accident. It is impossible to ascertain the condition of the reactor vessel without analyzing the hard physical data by sampling the weld-based capsule coupon and doing a complete analysis. Continued operation of the Palisades nuclear power plant without analyzing the coupon designated to be sampled more than seven years ago means that Entergy may be operating Palisades as a test according to 10CFR50.59. III HISTORY OF REACTOR EMBRITTLEMENT AT PALISADES 9. Designed and constructed by Combustion Engineering (CE), the Palisades nuclear power plant, began operation in 1971 making it one of the oldest operating reactors in the United States. It was the first large-scale commercial reactor vessel designed and fabricated by CE. 10. According to the NRC: Reactor pressure vessels, which contain the nuclear fuel in nuclear power plants, are made of thick steel plates that are welded together. Neutrons from the fuel in the reactor irradiate the vessel as the reactor is operated. This can embrittle the steel, or make it less tough, and less capable of withstanding flaws, which may be present. 2 11. When CE first fabricated the Palisades reactor vessel during the mid-to-late 1960s, the metal used for welding the nuclear reactor pieces together contained metallic components, like copper, that are now considered unacceptable due to impurities that cause Neutron Embrittlement. These impurities were only one piece of the 2 http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/prv.html Page 4 of 23 problem that has plagued the Palisades Nuclear Power Plant since its inception. The likelihood of nuclear reactor embrittlement and the importance of surveillance samples within the Palisades reactor cannot be traced solely to the impurity in its weld metal. Even prior to Palisades start-up, the Atomic Energy Commission (AEC) identified other potentially serious problems3. On January 27, 1970, Joseph Hendrie, Chairman, Advisory Committee on Reactor Safeguards, wrote a letter to Glenn Seaborg, Chairman, U.S. Atomic Energy Commission, in which he said, ...The nuclear steam supply system for the Palisades Plant is the first of the Combustion Engineering line currently licensed for construction. A feature of the Palisades reactor is the omission of the thermal shield. Studies were made by the applicant to show that omission of the shield would not adversely affect the flow characteristics within the reactor vessel or alter the thermal stresses in the walls of the vessel in a manner detrimental to safe operation of the plantÉ Surveillance specimens in the vessel will be used to monitor the radiation damage during the life of the plant. If these specimens reveal changes that affect the safety of the plant, the reactor vessel will be annealed to reduce radiation damage effects.

The results of annealing will be confirmed by tests on additional surveillance specimens provided for this purpose. IV NEUTRON EMBRITTLEMENT 12. Neutron radiation reduces the strength of metallic materials as in the steel and the welds of the steel nuclear reactor vessel, which holds the nuclear fuel and therefore constitutes the most important part of the nuclear reactor. The nuclear chain reaction inside the reactor that is created to generate energy from high-energy electrons also creates neutrons that impinge upon the inner side of the steel reactor vessel damaging the metal at a nano level and leading to metal embrittlement of reactor vessels. This neutron bombardment weakens all the metal in the vessel, and especially the welds that are made from softer metals. Moreover, these metallic impurities in the welds lead to rapid degradation of the welds from the neutrons bombardment creating the neutron embrittlement phenomena leaving a brittle 3 Joseph M. Hendrie, Chairman, Advisory Committee on Reactor Safeguards, letter to Glenn T. Seaborg, Chairman, U.S. Atomic Energy Commission, "Report on Palisades Plant," January 27, 1970.

Page 5 of 23 nuclear vessel at great risk of cracking. As detailed in the JOM (Journal of Metallurgy) article, Embrittlement of Nuclear Reactor Pressure Vessels by G.R. Odette and G.E. Lucas: Neutron irradiation embrittlement could limit the service life of some of the reactor-pressure vessels in existing commercial nuclear-power plants. Improved understanding of the underlying causes of embrittlement has provided regulators and power-plant operators better estimates of vessel operating margins.4 13. By the early 1980s, even the NRC publicly identified the issue of nuclear reactor neutron embrittlement as so serious that the New York Times wrote a special story on the issue, entitled: Steel Turned Brittle By Radiation Called A Peril At 13 Nuclear Plants.5 HARTFORD, Sept. 26Ñ The thick steel shells É 12 other reactors around the country are being turned brittle by radiation so rapidly, nuclear regulatory officials say, that some of the plants may become unsafe to operate by the end of next year. Utilities and the Nuclear Regulatory Commission are trying to determine the gravity of the problem, but commission staff members say it is certain that at least some of the plants will need substantial repairs. One high-ranking staff member said that to assure safety, some reactors might have to be modified or shut down by the end of next year.

On the information available today, I would start to say we'd get very nervous after another year or so, said the staff member, Dr.

Thomas Murley, director of safety technology.

14. Less than a decade after the Palisades nuclear reactor began operating, the first capsule samples began indicating severe embrittlement. These metallic capsule samples were put in place in order to determine whether or not neutron bombardment within the nuclear reactor was damaging and embrittling the steel vessel and its welds. 4 Light Water Reactors: Overview: Embrittlement of Nuclear Reactor Pressure Vessels, G.R. Odette and G.E. Lucas, JOM, 53 (7) (2001), pp. 18-22 http://www.tms.org/pubs/journals/jom/0107/odette-0107.html 5 Steel Turned Brittle By Radiation Called A Peril At 13 Nuclear Plants, Matthew L. Wald, Special to the New York Times, September 27, 1981 Page 6 of 23 15. During the last 33 years since that first national warning was issued by the NRC about severe embrittlement, only one nuclear reactor, Yankee Rowe, was permanently shutdown as a result of it becoming unsafe due to embrittlement. Of greatest concern is the fact that the NRC has acknowledged as recently as March of 2013 that Palisades Nuclear Power Plant is now one of the worst and most severely embrittled reactors in the country, and yet it is still allowed to operate. The NRC stated, During the March 19 webinar, it was stated that Palisades is one of the most embrittled plants. 6 16. When the Rowe nuclear power plant was permanently closed, the nuclear industry and its regulators were presented with the incredible opportunity to actually test an embrittled vessel and thereby strengthen the accuracy of the analytical underpinnings of embrittlement analysis. Unfortunately, the nuclear industry and its regulators did not avail themselves of the opportunity to conduct accurate destructive tests on portions of the Rowe reactor, and the vessel was decommissioned without being tested. The industrys choice not to collect Rowe embrittlement data has left the Palisades reactor as one of the most damaged in the nation. By its continued operation as an embrittlement experiment, likely in violation of 10 CFR 50.59, the Palisades nuclear plant has become the symbol of a regulator-endorsed national test attempting to determine how long a damaged vessel can continue to operate without failing and having a major radiation release to the highly populated areas surrounding the plant. 17. Thus far, the industry has not created any method by which it can directly measure the neutron bombardment to the wall of the nuclear reactor other than to sample the coupons of metal welds put inside each vessel when it is manufactured. These capsule coupons were designed to be removed periodically, so that each one may be subjected to destructive testing in order to directly measure the vessels level of embrittlement. There were 8 coupons installed originally, and 2 supplements added later. Of the 8 original coupons, 4 have been removed and tested. The 2 6 NRC Statement http://pbadupws.nrc.gov/docs/ML1310/ML13108A336.pdf Page 7 of 23 supplements have also been removed and tested.7 Four capsules remain available for testing. 18. According to the NRC, the most recent capsule sample was removed in 20038. The last two capsules removed from Palisades were capsule SA-240-1 (removed in 2000) and capsule W-100 (removed in 2003).

19. Rather than perform the appropriate metallurgical embrittlement tests, Rowe chose to shut down. Palisades has chosen a different tact, to mathematically analyze its embrittlement rather than perform additional metallurgical measurements and tests. Because the Palisades Nuclear Power Plant is operating with such severe embrittlement and has refused to test its remaining capsules [coupons], it appears to be operating in a test or experimental capacity. 20. According to the evidentiary data in this case, four samples currently remain within the Palisades reactor vessel9. However, since license renewal approval, Palisades requested and the: NRC approved a schedule change which left an additional capsule in the reactor pressure vessel (RPV) which would have been removed in 2007. Therefore there are three capsules in the RPV which can be used to determine properties of neutron irradiation.

One capsule is scheduled to be removed during the period of extended operation, and this is tentatively scheduled around 2019.

In addition to the capsules used to determine properties of neutron irradiation, one thermal capsule is also in the vessel which can measure thermal exposure effects on the metal, and is available for future use. So there are currently a total of four capsules in the RPV.10 7 http://pbadupws.nrc.gov/docs/ML1204/ML12040A315.pdf, Footnotes 77-80 pertain to Palisades, on p.81/94. December 11, 2011: EPRI Final Report, "Materials...PWR Coordinated RVSP [Reactor Vessel Material Surveillance Program]." See Palisades on Pages 38 to 39 of 94 on PDF counter, including Table 6-40, Palisades Current [Surveillance Capsule] Withdrawal Schedule." 8 http://pbadupws.nrc.gov/docs/ML1310/ML13108A336.pdf 9 http://pbadupws.nrc.gov/docs/ML1310/ML13108A336.pdf 10 Ibid Page 8 of 23 21. Almost half of the initial capsules [coupon samples] installed 43 years ago still remain inside the embrittled nuclear reactor. The next scheduled coupon removal has been postponed until 2019. If the NRC continues to allow Entergy to postpone the Palisades sampling until 2019, then no accurate current assessment of Palisades severe embrittlement condition exists. Astonishingly, it will be 16 years since the last sample was reviewed and analyzed if Palisades adheres to the 2019 removal date. 22. Using an incredible display of circular logic, on June 5, 2014, NRC Chair Macfarlane was asked why Palisades had not removed more surveillance samples to determine the severity of the embrittlement. The Chair deferred to the staff, which answered that no additional samples had been withdrawn because if samples were withdrawn, there would be no more remaining samples to withdraw!11 Rather than confirming these estimates with physical testing of actual samples that have been continuously irradiated during the last 43 years of operation, the NRC prefers to defer to the calculational predictions created by Palisades. 23. Moreover, the NRC first claimed it was very nervous about vessel embrittlement more than 30 years ago. In spite of these legitimate concerns, the NRC continues to allow Entergy to operate its Palisades Nuclear Power Plant in a compromised and test condition. This old and compromised reactor vessel continues to operate well outside the bounds of its design and fabrication without any modifications to the severely embrittled reactor pressure vessel. Instead of maintaining safety parameters during the last three decades, even in the aftermath of five nuclear meltdowns, the NRC has allowed Palisades to make unrealistic, unsupported and imprudent safety calculations based on little more than probabilistic risk, rather than real scientific analysis of hard data that is available inside the Palisades reactor. 24. Three factors have been created by Entergy and accepted by the NRC that specifically allow Palisades to continue to generate electricity: 11 See the affidavit of three eyewitnesses attached to this motion.

Page 9 of 23 24.1 The configuration of the fuel in the reactor core has been changed to allegedly reduce the number of neutrons impinging the wall of the nuclear reactor vessel. It is possible that these changes may be reducing the number of new neutrons now damaging the reactor pressure vessel welds and therefore these changes are not disputed in this affidavit, but there is no doubt that impingement, while reduced, is still occurring. Had Palisades installed a thermal shield when it became operational, these core changes would have been unnecessary. 24.2 The NRC has allowed Palisades to compare itself to reactors of disparate designs from other vendors, built in different years and operating at diverse power levels. 24.3 In an effort to save money and continue to operate the Palisades Nuclear Power Plant, its owners have claimed that new analytical techniques and regulations make it safe to continue to operate Palisades. In actuality, these recently developed techniques have reduced the margin of safety at Palisades from that originally designed and licensed to safety standards meant to protect public health and safety. These analytical changes continue to reframe embrittlement calculations, so that just as one technique begins to indicate vessel failure might be imminent creating a Pressurized Thermal Shock (PTS) accident, the plants engineers develop a new analytic methodology that claims that Palisades embrittlement is not as severe as indicated. This newly created methodology becomes the new standard applied to the Palisades embrittlement problem so that the compromised plant may still operate. 25. As a result of these changed analytical assumptions and the physical changes Entergy has made to the Palisades reactor core, the transition temperature between ductile and brittle metallic conditions caused by 43 years of neutron bombardment has been increased from 2001/4F to in excess of 2701/4F. While in 1981, calculations made under postulated Pressurized Thermal Shock (PTS) accident conditions showed that the reactor vessel would shatter at temperatures in excess of 2001/4F, Page 10 of 23 these newly created methodologies have enabled Palisades to operate well beyond the original design limits and clearly reduced the original margin of safety.

V SIMILAR PLANT [AKA: SISTER PLANT] COMPARISONS 26. As the 811 MWe Palisades NPP12 approached the end of its original 40 year life, Palisades filed for a license renewal that would allow the Palisades plant to operate for 20 more years. While the issue of Neutron Embrittlement was discussed by regulators at that time and was a significant concern for citizens living in proximity to the plant, the NRC ignored the problem at Palisades, by allowing Entergy to compare Palisades to other similar plants, sometimes called sister plants, that thus far have not exhibited significant signs of reactor metal embrittlement. To date, an exhaustive review of NRC regulations has not unveiled any regulations that allow for such comparisons, and no record of scientific validation of such methodology. 27. H. B. Robinson 2, a 724 MWe plant that began operation in 197113, and Indian Point 2 and 3, two 1,024 and 1,041 MWe 14 reactors that began operation in 1974 and 1976, are the nuclear plants that the NRC has considered similar sister plants and has therefore allowed Entergy to compare these reactor vessels at these plants with the aged and embrittled Palisades reactor vessel. The technological problem with comparing the two Indian Point reactors and H.B. Robinson with the Palisades NPP, is that the chosen plants are very dissimilar. The Palisades vessel was designed and constructed by Combustion Engineering while the other three aforementioned reactor vessels at H. B. Robinson and Indian Point are a Westinghouse design. While it is true that the material used to weld the reactor plates together to create the reactor vessel is similar among the four plants, the dramatically different nuclear core design and operational power characteristics make an accurate comparison impossible. The difference between the Westinghouse nuclear cores and the Combustion Engineering nuclear core impacts 12 http://www.entergy-nuclear.com/plant_information/palisades.aspx 13 http://www.duke-energy.com/power-plants/nuclear/robinson.asp 14 http://www.entergy-nuclear.com/plant_information/indian_point.aspx Page 11 of 23 the neutron flux on each reactor vessel, thus making an accurate comparison of neutron bombardment and embrittlement impossible. 28. By allowing Entergy to make this comparison between so-called similar sister-plants, the NRC is allowing Entergy to significantly dilute Palisades embrittlement calculations. Paradoxically, while the NRC is allowing the comparison among Palisades allegedly similar sister plants it has not thus far required H. B. Robinson Unit 2 or the two Indian Point plants to assess their embrittlement potential by incorporating the Palisades data. 29. Entergy has claimed that the Palisades plant has similar metallurgical characteristics in its welds to the three other aforementioned plants, and those similar sister plants have thus far shown relatively little embrittlement, unlike Palisades. Entergy then extrapolates this data to claim that therefore Palisades is safe to continue operating. This rogue comparative data is not sound scientific methodology and clearly places the operations of the Palisades NPP in the experimental test venue, possibly as delineated in 10CFR50.59. VI SIGNIFICANT ANALYTICAL PROBLEMS 30. When comparing similar sister plants, the most significant analytical problem is the extraordinary difficulty comparing data from four separate plants while still maintaining one standard deviation (1!) or 20% between all the data. According to the Palisades Reactor Pressure Vessel Fluence Evaluation, one standard deviation is required, however there has never been a discussion of how this was achieved between the four sister units:15 During the first 14 operating fuel cycles at the Palisades plant, five sets of in-vessel surveillance capsule dosimetry and three sets of ex-vessel dosimetry were irradiated, withdrawn, and analyzed. The results of these dosimetry evaluations provide a measurement data base that can be used to demonstrate that the neutron fluence calculations completed for the 15 ML14316A207, Attachment 4, Westinghouse, WCAP-15353 Supplement 2 NP, Revision 0, Palisades Reactor Pressure Vessel Fluence Evaluation, July 2011.

Page 12 of 23 Palisades reactor meet the uncertainty requirements described in Regulatory Guide 1.190.[6] That is, the calculations and measurements should agree within 20% at the 1! level. 31. I note that Westinghouse states that five sets of in-vessel surveillance capsule dosimetryÉwere irradiated, withdrawn, and analyzed; yet the Dec. 11, 2011 EPRI document cited previously says 4 sets, initially installed, and 2 supplemental sets, added later, or 6 sets have been analyzed. I cannot account for the discrepancy between the Westinghouse and EPRI data. 32. A 1! analysis appears to be binding within the Palisades data. Moreover, the NRC lowers the bar when comparing data from similar sister plants that are included in Entergys analysis of the Palisades reactor vessel without requiring the same 1! variance with Palisades. 33. There can be no assurance that the 20% error band at Palisades encompasses the 20% error band at the Robinson or Indian Point plants. To compare this different data without assurance that the 1! variance from each plant overlaps the other plants lacks scientific validity. 34. In addition to the problems associated with a 1! analytical comparison, there is extraordinary variability between the neutron flux across the nuclear core in this Combustion Engineering reactor. For instance, Table 2.2-3 from the same WCAP report shows a flux variation of as much as 300% between the 45-degree segment and the 75-degree segment. It is mathematically implausible that a 20% deviation is possible when the neutron flux itself varies by 300%.

Page 13 of 23

35. Not only is there extraordinary variability with neutron flux, but also the neutron fluence in each portion of the nuclear core can be higher or lower in an unpredictable fashion between different fuel cycles. Table 2.2-4 of the same WCAP is illustrative. The 30, 45, and 60-degree segments show an increase in neutron fluence after the 18th cycle, while the 0, 15, 75 and 90-degree segments show a decrease in neutron fluence over time.

Page 14 of 23

36. This extraordinary neutron variability occurs within the Palisades nuclear reactor itself. If this variability exists within the Combustion Engineer reactor core, it is reasonable to question the variability in the Westinghouse cores of the purported similar sister units. The net effect is that while 1! accuracy within the Palisades reactor may be attainable, comparing other reactors and expecting common 1! variations is impossible.

Page 15 of 23 37. Even though Westinghouse demands fluence accuracy of 20%, documentation available in ADAMS for Palisades shows that this level of accuracy is impossible to achieve.16 Section 4.3 Calculational Uncertainty A number of factors contribute to the uncertainty in the projected peak fast fluence at the reactor vessel wall. These factors are due to the conversion of measured activity data to fluxes, uncertainties in material composition, neutron cross sections, power distributions, as-built core/vessel dimensions and cycle-by-cycle variation in the fast flux lead factors. An uncertainty of [plus or minus] 25% is estimated in the calculated vessel wall fluence, typical of current neutron transport methodology uncertainties...] (Emphases Added) 38. An accurate prediction of exactly where the fluence reaches its highest level is critical to embrittlement calculations at Palisades. While fluence at the 0 degree location appears to be decreasing according to Westinghouse, fluence is increasing at the 30-degree location. This is important because the limiting vessel welds are at these specific locations. Palisades data in the ADAMS database indicates that Accumulated fast fluence distributions at the end of Cycle 9 and EOL at the clad-base metal interface is shown in Figure 4.4. Based upon Reg. Guide 1.99, Revision 2, fluence limits corresponding to base metal, axial, and circumferential welds are also presented in Figure 4.4. From this figure it can be noted that the fluence values at the axial welds at 0 [degrees] and 30 [degrees] are limiting the life of the Palisades reactor pressure vessel. Table 4.2 summarizes the cycle specific fluence...and accumulated fast fluence at the clad-base metal interface for each of Cycles 1 through 9. For the selected azimuthal locations: 01/4 (axial weld location), 171/4 (maximum of peak at base metal), 301/4 (axial weld location) and 451/4, effective full power years...for each cycle and the accumulated EFPY's are also presented. Table 4.3 provides the fluence limit violation dates with Cycle 9 fluence rates for plant operations beyond the end of Cycle 8 date of September, 1990.]17 [Emphasis Added]

16 pbadupws.nrc.gov/docs/ML0527/ML052720270.pdf, May 17, 1990 17 pbadupws.nrc.gov/docs/ML0527/ML052720270.pdf, page 33, first and second paragraphs Page 16 of 23 39. In my opinion, if Palisades installed a thermal shield when it became operational, the issues related to embrittlement would not have occurred. The Westinghouse Analysis delineates that a 20% variation is mandatory, yet the effective fluence variability can be as high as 300%; therefore, the analytical data does not support relicensure without destructive testing and complete embrittlement analysis of additional capsule samples. 40. In at least one case, Palisades was allowed to ignore the scientifically acceptable 1! variation identified by Westinghouse (above). That is, the calculations and measurements should agree within 20% at the 1! level. 41. Despite this 1! requirement, on February 28, 1984, the NRC authorized deletion of sample SA-60-1 from consideration because its measured neutron value exceeded this 1! variation 18. As of October 31, 1982, the licensee indicates that Capsule A-60 had accumulated approximately 8.7x1018 n/cm2 (E>1MeV) neutron fluence. Since the neutron fluence accumulated by the Capsule is significantly greater than the predicted EOL fluence for the Palisades reactor vessel and Capsule A-240 has provided material properties that can be utilized to predict the EOL material properties of the Palisades reactor vessel, Capsule A-60 will provide no useful fracture toughness data and may be deleted from the surveillance program. 42. Simply put, this particular sample was discarded precisely because it gave an answer that would have required Palisades to be shut down. It follows that the analytical basis for continuing operation is distorted, and since specific sample data has been disregarded, Entergy may be putting the public at risk by operating Palisades under unsafe conditions.

Page 17 of 23 VII NEW AMENDMENTS TO THE PALISADES LICENSE 43. Evidently the licensing framework that the NRC is applying to allow Palisades to continue to operate until 2017 includes both non-conservative analytical changes and mathematically dubious comparisons to allegedly similar sister reactor vessels. As Palisades' neutron embrittlement dilemma continues to worsen as the plant ages, Palisades has repeatedly requested life extensions. The table below is illustrative of how embrittlement problems have been ignored and deferred for decades by Palisades' management.

These predicted dates are far short of the assumed nominal plant operating license expiration date of March 2011. 20 Inside NRC on December 12, 1994 "As recently as October 28th [1994], when NRC staff issued Secy 94-267, "Status of Reactor Pressure Vessel Issues," the agency projected that Palisades would reach its PTS screening criteria in 2004. On November 18

[1994], Consumers Power submitted a revised evaluation of the PTS issue that indicated the vessel would reach the critical level in 1999." 21 Recent NRC Staff Evaluations of RPV Structural Integrity Data for PTS Events https://adamswebsearch2.nrc.gov/webSearch2/main.jsp?AccessionNumber=ML031070449, Excerpt p. 3 of 9 The staff issued a safety evaluation report to the licensee for Palisades on the variability of reactor vessel weld properties for the Palisades reactor vessel on April 12, 1995 [Ref.

2]. The staff agreed with the licensee's best estimate analysis of the chemical composition of the reactor vessel welds and concluded that continued operation through Cycle 14 (late 1999) was acceptable. As discussed previously, while performing the evaluation, the staff noted larger variability in the chemical composition of the welds compared to that assumed for the development of the PTS rule. The staff evaluated the implications of this larger variability on the PTS rule generic margins for the Palisades vessel using the same analytic methods as those used in formulating the rule. The staff has reviewed the other PWR vessels and, based upon currently available information, believes that the Palisades vessel will reach the PTS screening criteria by late 1999, before any other PWR. 22 ML050940429 23 ML110060692 24 ML13176A412 25 ML14211A524 Page 19 of 23 45. Now, juxtaposed against this industry unique background of deteriorating embrittlement conditions within the Palisades reactor, the aged plant requests two more license amendments: 45.4 Disturbingly, one of these amendments proposes a significant analytical deviation from the regulatory requirements of 10CFR50.61 to 50.61a (Alternate Fracture Toughness Requirements). This newest amendment request once again introduces further non-conservative analytical assumptions into the troubled calculational history of Palisades 43 operational years.26 45.5 On top of the aforementioned analytical deviation is an even more alarming License Amendment Request (LAR) containing an equivalent margins evaluation that was only recently released from the public document room, even though the document was filed more than four months ago in July 2014. Once again, Entergys Palisades NPP is seeking NRC approval for another untried methodological approach to measure the neutron bombardment induced reactor vessel embrittlement in such a manner, that the Palisades NPP could continue to operate under additional relaxed measurement conditions.27 46. A License Amendment Request (LAR) is a serious request for any operating nuclear power plant because it seeks to assure the public that if these changes are made the plant will still retain and operate within its safety margins and be as safe as it was before the changes were implemented. From the evidence reviewed, it appears that this specific LAR is required because prior evaluations suggest that three portions of the nuclear reactor vessel will not meet the NRC required 50 ft-lb ductility stress limit. It also appears, from the five documents attached to the LAR, that Westinghouse has reanalyzed and manipulated the Palisades data so that the final calculations keep the reactor vessel within the regulatory acceptable range above the minimum 50 ft-lb ductility stress limit. 26 ML14211A524 27 ML14316A370 Page 20 of 23 47. Finally, the evidence I reviewed in the five attachments to the LAR, suggests that Entergy may have chosen not to apply the Westinghouse reanalysis because that analysis would not allow Entergy to operate the Palisades NPP in the manner it wished. As a result, Entergy submitted what it calls an equivalent margin analysis to show that even in the portions of the nuclear reactor that did not meet the NRC minimum required 50 ft-lb ductility stress limit, the reactor will still provide sufficient safety margins for continued operation of the Palisades Nuclear Power Plant.

VIII TEST OR EXPERIMENT 48. The latest equivalent margins evaluation is a red flag indicating that the reactor vessel at Palisades is operating in more uncharted territory than imagined.

Basically, Entergy is proposing to operate its Palisades NPP well outside the norm by proposing to reanalyze the deteriorating metallurgical conditions without using the readily available physical samples that are designed specifically for this purpose. 49. Even before these two new proposed amendments to its license, the NRC is already on record telling the Advisory Committee on Reactor Safeguards (ACRS) that Palisades is special.28 According to the transcript: Member Banerjee: Yes, but I mean what is special about Palisades? That's what I was going to ask.

Mr. Kirk: Well, there are so many things that are special about Palisades. 50. The problems identified by the need for an equivalent margins analysis in conjunction with Palisades long history of metallurgical concerns proves that continued operation in the future will be on an experimental basis. Clearly the special condition of the Palisades reactor and its ranking as one of the most 28 ACRS subcommittee meeting of Metallurgy and Reactor Fuels, October 16, 2014 transcript, ML14296A342, Page 30 [31 of 168 on PDF counter].

Page 21 of 23 embrittled reactors in the United States qualify its continued operation as a test. Therefore, it appears that these newly proposed changes to the Palisades license and possibly to the statutory definition of experiment within 10CFR50.59 will trigger the requirement for additional public scrutiny in the form of a public licensing process IX ALTERNATIVE TO AN ANALYTICAL LICENSE CHANGE As the Palisades NPP continues to amend its operating license by reanalyzing the projected end of life for its compromised and embrittled reactor vessel, extrapolation beyond 2014 is problematic and potentially dangerous. It has been more than a decade since an actual sample was removed from inside the Palisades nuclear reactor vessel, so there is no physical data to benchmark the analysis described in 10CFR50.61 and in 10CFR50.61(a). Even the NRC has acknowledged that its 50.61(a) models require validation in order to provide assurance of safe operation at Palisades29. As far as weakening NRC safety regulations by approving the alternate rule, 10 CFR 50.61a: as was mentioned during the webinar, this alternate rule is justified by an improved state of both theoretical and practical knowledge, more accurate models, and model validation. (Emphasis Added) 51. Validating the analytical models by testing additional samples gives Entergy and the NRC Regulators a methodology by which to assure the public that Palisades continued operation in its embrittled condition does not jeopardize public health and safety. Abundant capsule coupon samples remain inside the reactor and should be removed and tested rather than the Entergy proposal of a license change based only upon an extrapolated analysis.

29 http://pbadupws.nrc.gov/docs/ML1310/ML13108A336.pdf Page 22 of 23 X CONCLUSION 52. In any scientific and engineering analysis, both the analysis and hard field data must be linked. At Palisades, more than a decade has transpired since the last capsule coupon was removed and analyzed, so it is impossible to assure that the new analysis proposed by Palisades meets the 1! requirement without removing at least one capsule coupon and performing the requisite destructive testing. 53. The NRC would seem to agree that using all possible samples is important to an accurate outcome. According to the October 16, 2014 meeting notes [November 6, 2014 transcript] of the ACRS:30 Éthe vehicle for doing that is doing a statistical comparison of a particular reactor's plant specific surveillance data with the general trends. (Emphasis Added) 54. Until a new capsule sample is removed and analyzed, the analytical assumptions created for the proposed license amendment are unable to be validated and verified. In my professional opinion, the NRC should not approve any change to Palisades operating license without such validation and verification. 55. In order to protect public health and safety, the Code of Federal Regulations is the governing document for the operation of all US nuclear power reactors. Palisades record is clear. Analysis is no replacement for testing the capsule coupon. Quite simply, operating the Palisades nuclear reactor without the removal and analysis of a capsule sample for almost two decades (2003 to 2019 is 16 years) seems to qualify the operation of the Palisades NPP as a Test or Experiment under 10CFR50.59. A License Amendment Request that seeks to extend the life of an already severely embrittled reactor should be considered a Test or Experiment triggering a full evaluation and full public participation in the license amendment process including full public License Amendment Hearings and careful analysis shared in a public forum. 30 http://pbadupws.nrc.gov/docs/ML1432/ML14321A542.pdf, page 20, [Page 22 of 268 via PDF].

Special Remediation Expertise: Director of Engineering, Vice President of Site Engineering, and the Senior Vice President of Engineering at Nuclear Energy Services (NES) Division of Penn Central Corporation (PCC) ! NES was a nuclear licensee that specialized in dismantlement and remediation of nuclear facilities and nuclear sites. Member of the radiation safety committee for this licensee. ! Department of Energy chose NES to write DOE Decommissioning Handbook because NES had a unique breadth and depth of nuclear engineers and nuclear physicists on staff.  ! Personally wrote the Small Bore Piping chapter of the DOEs first edition Decommissioning Handbook, personnel on my staff authored other sections, and I reviewed the entire Decommissioning Handbook.  ! Served on the Connecticut Low Level Radioactive Waste Advisory Committee for 10 years from its inception.  ! Managed groups performing analyses on dozens of dismantlement sites to thoroughly remove radioactive material from nuclear plants and their surrounding environment.  ! Managed groups assisting in decommissioning the Shippingport nuclear power reactor.

Shippingport was the first large nuclear power plant ever decommissioned. The decommissioning of Shippingport included remediation of the site after decommissioning.  ! Managed groups conducting site characterizations (preliminary radiation surveys prior to commencement of removal of radiation) at the radioactively contaminated West Valley site in upstate New York. ! Personnel reporting to me assessed dismantlement of the Princeton Avenue Plutonium Lab in New Brunswick, NJ. The labs dismantlement assessment was stopped when we uncovered extremely toxic and carcinogenic underground radioactive contamination.  ! Personnel reporting to me worked on decontaminating radioactive thorium at the Cleveland Avenue nuclear licensee in Ohio. The thorium had been used as an alloy in turbine blades.

During that project, previously undetected extremely toxic and carcinogenic radioactive contamination was discovered below ground after an aboveground gamma survey had purported that no residual radiation remained on site.
