Preface

When I was initially contacted by the National Academies of Sciences, Engineering, and Medicine to chair this study, based on the Statement of Task I believed the problem we were asked to study was straightforward: Review the Department of Energy’s (DOE’s) plans to dilute and dispose of surplus plutonium material in the Waste Isolation Pilot Plant (WIPP). To me, this sounded like a systems problem—one that required scaling up of existing processes—but technically not very complex.

In that narrow scope, I was correct. The dilute and dispose plan is not technically complex. The true challenges lay in the many mostly nontechnical threads that are connected to the technical plan. As noted previously—yes, the plan is technically feasible; no, it does not meet the requirements of the U.S. Russian Plutonium Management and Disposition Agreement (PMDA) (as I understood it at the onset), an agreement that is further described within the main text of the report. But between these black and white answers are many shades of gray. I felt we were asked not only for the yes or no answers but also to deliver the best advice we could going forward. The committee’s advice evolved after its careful consideration of the multiple and highly interconnected and complex threads connected to DOE’s National Nuclear Security Administration’s (DOE-NNSA’s) dilute and dispose plan.

Many of the challenges connected to this disposition pathway are nontechnical but nevertheless important to understand in order to appreciate the committee’s final analysis and advice. This requires background information and explanation. The answers were straightforward, the advice not so. Complex issues are associated with PMDA noncompliance, which requires a basic understanding of the agreement. Capacity at WIPP is not a simple volumetric or mass-density calculation and the method in which DOE calculated it changed over the course of the study which also requires detailed explanation. As an alternative to the Mixed Oxide Fuel Fabrication Facility (commonly referred to as the “MOX plant”), the dilute and dispose plan, which encompasses four DOE sites and spans over 30 years, was and is under development and evolving. It is important to stress that the program was and is evolving in real time. Other DOE programs that emerged during this study, including the new focus on pit production, which affects three of the four sites within the dilute and dispose plan, also needed to be considered. Finally, even the full quantity of surplus plutonium considered for dilution and disposal at WIPP requires an understanding of past decisions on surplus plutonium disposition and the impacts of potential future ones. It was not simple arithmetic, as I had initially assumed. To those readers familiar with these issues, the committee’s resultant advice is concentrated in Chapters 4 and 5 of this report. To readers who seek background information, they are encouraged to read Chapters 2 and 3, which provide background on some of the complexities discussed above and details on DOE-NNSA’s dilute and dispose plans.

Finally, it is worth noting the political context at the start of and throughout this study. In November 2017, the MOX plant was under construction, and incorporation of the surplus plutonium into MOX fuel for irradiation in commercial nuclear power plants was the U.S. program of record for disposition. The MOX option was cancelled in the midst of the committee’s study in May 2018 and many documents related to the dilute and dispose plan were not available to the committee. This led us to the decision to release an Interim Report in December 2018 to provide initial timely guidance to Congress, who requested this study, on the nascent plan. Much of the committee’s advice in the Interim Report is echoed and strengthened in this final report after examining more evidence and exploring more deeply the many complex threads.

This report is the final product of an extremely dedicated diligent and collegial committee and Academies staff. I am enormously grateful to the outstanding assistance and remarkable professionalism of the National Academies staff in preparing the report, especially Laura Llanos and Toni Greenleaf, financial associates; Darlene Gros, senior program assistant, for logistical planning for all of the committee’s meetings and project administration; and Richard Rowberg, senior advisor, for his guidance

and his participation in the classified meetings and tour. Jenny Heimberg, study director, was my right and left arms in working through the subsequent complexities of this study. She dealt with the committee, staffers on the Hill, and agency representatives in a way that I could only admire. She got things done.

I am especially thankful for the opportunity to lead this distinguished committee. I thank the members of the committee for their dedication, willingness to teach and to learn, and for their time and energy. The collegiality of this group, although holding a diversity of opinions, was an enormous delight as the study evolved.

The purpose of this independent review is to provide candid and critical comments that will assist the National Academies of Sciences, Engineering, and Medicine in making each published report as sound as possible and to ensure that it meets the institutional standards for quality, objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process.

We thank the following individuals for their review of this report:

In addition, portions of this report were fact checked by the Department of Energy’s National Nuclear Security Administration (DOE-NNSA) and Office of Environmental Management (DOE-EM) as well as the Environmental Protection Agency (EPA). In particular, we thank Lyndsey Adams (DOE-NNSA), Betsy Forinash (DOE-EM), William Kilmartin (DOE-NNSA), and Tom Peake (EPA). We are thankful for their contributions toward improving the accuracy of the report’s content.

The committee also wishes to thank the study sponsor, DOE-NNSA, for supporting this project. Special thanks go to William Kilmartin and Lyndsey Adams, who served as the points of contact with DOE-NNSA, and Betsy Forinash, who served as the point of contact with DOE-EM, for their tireless work addressing the many sets of questions generated by the committee throughout the duration of the study.

Although the reviewers listed above provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations of this report nor did they see the final draft before its release. The review of this report was overseen by Margaret S.Y. Chu, M.S. Chu + Associates, LLC, Review Coordinator, and Chris G. Whipple, ENVIRON (Retired), Review Monitor. They were responsible for making certain that an independent examination of this report was carried out in accordance with the standards of the National Academies and that all review comments were carefully considered. Responsibility for the final content rests entirely with the authoring committee and the National Academies.

In 2018, the National Academies of Sciences, Engineering, and Medicine issued an Interim Report evaluating the general viability of the U.S. Department of Energy's National Nuclear Security Administration's (DOE-NNSA's) conceptual plans for disposing of 34 metric tons (MT) of surplus plutonium in the Waste Isolation Pilot Plant (WIPP), a deep geologic repository near Carlsbad, New Mexico. It provided a preliminary assessment of the general viability of DOE-NNSA's conceptual plans, focused on some of the barriers to their implementation. This final report addresses the remaining issues and echoes the recommendations from the interim study.
