Senior Technical Review Group Report July 1996


Comments on the
Predecisional Draft of the Joint U.S.-Russian Study of Plutonium Disposition
Options Steering Committee Summary Report

The Group reviewed the predecisional draft of the summary of the above mentioned report and its 2-page executive summary. The following comments are offered.

1. The Report is a reasonably comprehensive review of disposition options as seen by the two sides together with assessments of pros and cons of each again as seen by the two sides.

2. Most notable, however, is the absence of any concrete recommendations as to the means by which agreed further work and investigation can be effected. As was clearly demonstrated at the recent meeting of the joint study group in St. Petersburg, decisions or conclusions reached at the technical level must be ratified and moved forward at the political decision-making level. This was not accomplished at St. Petersburg. Yet there is no reference to the need for a mechanism to accomplish this either in the report summary or its brief Executive Summary. This deficiency should be rectified in the conclusion of the document with an affirmative statement as to the need for such a decision making mechanism. Both sides should agree as to the need for an intergovernmental body to give effect to this recommendation. An Executive Agreement or a treaty should confirm agreements reached and by involving the legislative process convey a measure of permanence to them.

3. It was noted that Russia has yet to declare its surplus weapons plutonium. This is in contrast to the frequently repeated understanding that there will be essential equivalence in the U.S. and Russian declarations (i.e. about 50 tons each). This should be vigorously pursued consistent with the basic purpose to get Russia to dispose of its weapons material.

4. Executive Summary, Page 2
Given the long time scale of the disposition process and the likelihood that much of the retired plutonium will remain in pit form for many years, bilateral monitoring during the period is essential to assure both countries that the Pu has really been and remains demilitarized.

5. Summary, Page 17
No mention is made of the possible transfer of the Siemens MOX plant to Russia. If this was considered by the Joint Group it should be mentioned. If it was not considered, it should have been.

6. Summary, Page 25
The characterization of weapons-grade plutonium as "somewhat more attractive for use in weapons" is a serious understatement in the context of national retrieval and reuse. This characterization is acceptable for "resistance to (subnational) theft and diversion," but the evidence is overwhelming that, for the U.S. and, in all probability, Russia, reactor-grade plutonium is much less attractive for use in weapons. The sentence should be amended along the lines of: "Given the fact that the U.S. and Russian nuclear weapons technology and stockpiles are based on weapons-grade plutonium, reactor-grade plutonium would be much less attractive for use in any weapons programs than plutonium of weapons-grade."

7. Summary, Page 26
The section entitled "Geologic Disposal" is established as a coordinate section of the report with the reactor and immobilization options. This is misleading and inaccurate. Conversion to the "spent fuel standard" by either the reactor or immobilization options is not dependent on geologic disposal. It is, misleading to characterize geologic disposal as the "final and concluding phase" in all disposition options. Moreover, there is no mention of the fact that geological disposal, even if accomplished, would be followed by 50 or more years of intentional accessibility to provide assurance of repository performance. This is an important fact that should be made clear.

8. Specific text changes:

  1. In paragraphs 2 and 3 of the two-page Executive Summary and in the summary document itself reference is made to "50 tons of excess weapons plutonium". In each case this reference should be revised to make it clear that is 50 tons on each side rather than a total for the two sides which could be inferred from the present text.

  2. Executive Summary (2 pages) page 1 paragraph 2 line 1 delete the word "both".

  3. Executive Summary (2 pages) page 5 paragraph 4 line 5 delete the word "could" and insert "might".
