Introduction

9. As a Vice President with Nuclear Energy Services (NES), a division of The Penn Central Corporation (PCC), and later as its Senior Vice President, I was responsible for its Engineering and Engineered Products divisions.

10. The Engineering and Engineered Products divisions of NES designed and fabricated nuclear fuel racks for dozens of nuclear power plants throughout the United States.

11. The NES fuel racks used boroflex neutron absorbers sandwiched between stainless steel. The time period when I was responsible for this NES effort was between 1981 and 1990.

Page 3 of 9

12. The NES division reporting to me also performed criticality calculations on these spent fuel racks.

13. Due to my direct working knowledge and expertise in this area, I can state with certainty that the K-effective criticality calculations conducted by this division and by our competitors did not include any aging issues related to long-term degradation of the boron neutron absorber.

14. Furthermore, neither NES nor other competitors ever assumed that the boron would slip and gradually move downward over time when k-effective calculations were performed.

Indian Point

15. My review of the Indian Point docket confirms that the record shows that boroflex neutron absorbers have indeed experienced degradation problems that were unanticipated when the racks were designed, constructed, and installed.

16. In my review of the 2001 08 27 Indian Point 2 Operating License Transferred to Entergy (ML012250459), I found several inaccuracies that I will discuss in my testimony.

3.1.4.2 Spent Fuel Storage Limitations On April 30, 2001, Con Edison submitted to the NRC a business plan, for years 2001 - 2005, that addresses many of the current and future challenges to the operation of the IP2 facility. In the business plan, Con Edison made the following statement:

At present, Indian Point is licensed to operate until 2013. However, the plants spent fuel pool can hold assemblies only until 2002. This issue has been exacerbated by the degradation of the spent fuel storage rack liner boron (Boraflex). Therefore, additional fuel storage is needed earlier than anticipated last year. Even premature shutdown of the plant would entail the continued operation of the Spent Fuel Pool at a cost of approximately xx million or more per year until the pool is emptied. All utilities operating nuclear plants have paid fees to the Department of Energy (DOE) for the development of a spent fuel storage facility. Unfortunately, for a variety of reasons, the DOE will not be able to receive spent fuel until 2010, at the earliest.

Page 4 of 9 Entergy Nuclear IP2, and ENO responded to this request in a letter dated June 6, 2001. In their response, the applicants noted that Con Edison is already in the process of addressing the Boraflex issue and evaluating potential solutions in order to regain storage locations within the SFP that are now considered to be unusable. Among the options being reviewed are: taking credit for soluble boron in the SFP water; and, taking credit for pre-discharge burn-up of the fuel stored in the SFP5. The response states that the ongoing activities to address spent fuel storage at IP2 are expected to provide sufficient storage capacity to retain full core off-load capability until just before the 2006 refueling outage. Entergy Nuclear IP2 and ENO also stated that, after closing, they will, implement appropriate actions to regain the storage spaces affected by Boraflex degradation and will pursue both on-site and off-site storage options. The applicants stated further that the costs of dry cask storage have been accounted for in the financial projections provided to the NRC in the application.

[Footnote 5 Above]5 Design analyses for spent fuel storage typically make the conservative assumptions that (1) the fuel within the SFP is all new fuel, which is more reactive than used (burned) fuel; and, (2) the water in the SFP is pure water. These assumptions lead to SFP rack designs that will, through their own inherent design features, prevent criticality in the SFP (Boraflex is one of those design features). In reality, except for just prior to, and during, a refueling outage, the fuel in the SFP has typically all experienced some burn-up and, thus, is less reactive. Additionally, the water in the SFP contains dissolved boron (soluble boron), a neutron absorber, that provides additional margin in preventing criticality in the SFP.

(ML012250459 page 20 of enclosure 4, 60th page of pdf file)

17. My experience with criticality design indicates that the statements above are incorrect for specific unanalyzed fuel configurations, and in fact an inadvertent criticality is possible under certain circumstances if the boroflex is degraded.

18. In particular, my experience managing the design of spent fuel racks indicates that there are circumstances when new fuel criticality is possible unless the boroflex retains its integrity.

19. More specifically, new fuel that is temporarily stored in spent fuel racks prior to loading it into the reactor may have an inadvertent criticality. The design as analyzed appears to be over moderated and not conservatively analyzed. In other words, as the concentration density decreases in the water surrounding the new fuel, K-effective may rise because there is less borated water and more reliance is placed

Page 5 of 9 upon the boroflex to absorb the spent fuel pool with its additional burden of fresh fuel.

20. Indian Points boroflex has indeed become degraded. Based upon my direct knowledge of criticality analyses performed on Cray super computers, the evidence shows the k-effective for new fuel stored on spent fuel racks in the spent fuel pool, the worst-case conditions in the scenario quoted above have not been adequately analyzed for Indian Point Units 2 and 3, even if the Boroflex had retained its integrity.

21. Furthermore, in my experience, in the event that there are steam voids in the water caused by fire or inadequate cooling, criticality is possible unless the boroflex retains complete integrity.

22. My personal knowledge of spent fuel rack criticality shows that the worst-case criticality occurs when the new fuel is surrounded by 90-percent-water and 10-percent-voids.

23. In my professional opinion, and based upon my professional experience as delineated in this declaration, the NRCs Safety Evaluation Report Related to the License Renewal of Indian Point Nuclear Generating Unit Nos. 2 and 3 is inadequate in its assessment of criticality issues (k-effective). adequately addresses

24. The criticality issues (k-effective) associated with the storage of new fuel in spent fuel racks where the boroflex is degraded, as it appears to be at Indian Point, has not been adequately analyzed and/or addressed in the NRCs Safety Evaluation Report Related to the License Renewal of Indian Point Nuclear Generating Unit Nos. 2 and 3.

25. More specifically, boroflex aging is not managed by the Indian Points aging management program, rather Entergy watches as the boron degrades, according to the Boroflex Monitoring Program detailed in the NRC Safety Evaluation Report Related to the License Renewal of Indian Point Nuclear Generating Unit Nos. 2 and 3 Docket Nos. 50-247 and 50-286 Entergy Nuclear Operations, Inc.

Page 6 of 9 3.0.3.2.3 Boraflex Monitoring Program Summary of Technical Information in the Application. LRA Section B.1.3 describes the existing Boraflex Monitoring Program as consistent with GALL AMP XI.M22, Boraflex Monitoring, with exceptions.

The Boraflex Monitoring Program prevents degradation of the Boraflex panels in the spent fuel racks from compromising the criticality analysis supporting the design of the spent fuel storage racks. The program relies on 1) areal density testing, 2) a predictive computer code, and 3) determination of boron loss through correlation of silica levels in spent fuel water samples to maintain the required five percent subcriticality margin. Corrective actions follow if test results find that the five percent subcriticality margin cannot be maintained because of current or projected Boraflex degradation. This program applies to IP2 only as no Boraflex is used for criticality control of IP3 spent fuel..

Conclusion. On the basis of its review of the applicants Boraflex Monitoring Program, the staff determines that those program elements, for which the applicant claimed consistency with the GALL Report are consistent. In addition, the staff reviewed the exceptions and their justifications and determines that the program is adequate to manage the aging effects for which it is credited. The staff concludes that the applicant has demonstrated that the effects of aging will be adequately managed so that the intended functions will be maintained consistent with the CLB for the period of extended operation, as required by 10 CFR 54.21(a)(3). The staff also reviewed the UFSAR supplement for this program and concludes that it provides an adequate summary description of the program, as required by 10 CFR 54.21(d).

26. Table 3.5.2-3, cited by the Staff and Entergy, appears to deal only with aging management of the stainless steel portions of the spent fuel pool rack during the period of extended operation and leaves the boroflex degradation issue completely unanalyzed.

27. Boroflex will continue to degrade despite the institution of any aging management program to the stainless steel within the fuel racks. Therefore, any fuel rack aging management program is wholly irrelevant to my contention because it still neglects the significant industry-wide issue of boroflex degradation. The other aging management programs (AMPs) cited by Entergy (Entergy Ans. at 21) also are not applicable to the unique condition of boroflex degradation because Entergy has only reviewed the anticipated period of extended operation rather than a complete

Page 7 of 9 operational history, and are therefore are also irrelevant to the aforementioned contentions.

28. Due to the industry-wide issue of boroflex degradation, on February 16, 2011 the NRC issued NRC Information Notice 2011-03: Nonconservative Criticality Safety Analyses For Fuel Storage that discusses the issue of k-effective criticality.

(ML103090055)

Both of these uncertainties, if not properly treated, may lead to non-conservative estimation of the maximum k-effective, and regulatory compliance may not be assured. Analyses with small margins to the regulatory limit are especially vulnerable to noncompliance with 10 CFR 50.68 and non-conservative technical specifications if these issues are present.

29. In NRC Information Notice 2011-03, the NRC itself acknowledges that there is a very small margin between criticality and non-criticality in densely packed spent nuclear fuel racks and that calculational uncertainties may indeed exceed the margin of difference.

30. Additionally, the October 28, 2009 NRC Information Notice 2009-26: Degradation Of Neutron-Absorbing Materials In The Spent Fuel Pool highlights the problems associated with degradation of boron used as a neutron absorber in a nuclear fuel rack. In this notice, the NRC alerts the nuclear industry that in certain circumstances more than 60-percent of the boron may have dissolved from the absorber.

(ML092440545)

The licensee performed in situ Boron-10 Areal Density Gauge for Evaluating Racks (BADGER) testing of approximately 2 percent of the storage locations, which revealed that the Boron-10 areal density of the SFP racks was, at a minimum, approximately one-third of its original design value.

31. Furthermore, NRC Information Notice 2009-26 also warns the nuclear power generators that The exact degradation mechanism or mechanisms are not clearly understood and in some circumstances the Boral contained in SFP racks can blister and the blisters could grow to a point where the water from the flux trap of the region 1 rack could be displaced with gas. This deformation has the potential to challenge dimensional assumptions made in the fuel pool criticality analysis.

Page 8 of 9

32. Finally, because there is no legal requirement that the fuel in the Indian Point Units 2 and 3 spent fuel pools is removed at shutdown, the fuel may remain in the spent fuel pool long after Entergys Indian Point license extension and its associated aging management programs have ended, maybe for decades after the eventual shut down of the nuclear power plants. Neither the aging management program nor any other license or license application document address this scenario.

33. In summary, Entergy has failed to provide adequate aging management plans for the spent fuel pool during this period and has specifically failed to create an aging management program for the spent fuel pool Boral panels.

Conclusion

34. My experience analyzing rack criticality indicates that a conservative criticality analysis does not appear to have been completed for the Indian Point Units 2 and 3 Fuel Racks.

35. More importantly, the lack of a conservative criticality analysis criticality analysis is compounded by the continuing degradation of boron absorbers in the Indian Point Units 2 and 3 fuel racks.

36. Finally, the NRC itself has issued a series of information notices alerting the nuclear power generators to spent fuel rack physical failures (identified in Information Notice 2009-26) and spent fuel rack analytical failures identified in (Information Notice 2011-03)

37. In conclusion, the evidence shows that the spent fuel pool aging management programs for the period of extended operation are inadequate to assure inadvertent criticality and the generic findings regarding 60-years of safe and minimal impact storage are not applicable to the spent fuel pool at Indian Point Units 2 and 3.

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.

Attachment 1 Page 11 of 14 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.
