The basis for the cost estimates Included Task Team and third-party judgments, the latter primarily from "advocates" for each of the treatment options, costs for comparable applications, and simple calculations. The Task Team estimated the major cost components of an al Minus spent fuel handling, treatment, storage, and disposal system and, for each of these components, the Task Team developed a consistent set of methodologies for estimating costs.

The Task Teen assumed that the existing infrastructure at the Savannah River site, including existing buildings and secondary waste treatment facilities, would be used in the treatment and storage program whenever practical. For example, the Task Team assumed that the aluminum spent filet would be received and stored in two existing wet storage facilities, the L-Basin and the Receiving Basin for Offsite Fuels (RBOF; see Figure I.2~.

The Task Team made a variety of other assumptions In its cost estimates, two of which are worm noting here. First, the Task Team assumed that the wet basins would be deinventoried as soon as possible after the spent fuel transfer facility was opened to reduce operating costs.

The Task Teen assumed that aluminum spent fuel at Savannah River would be reprocessed in the H Canyon at Savannah River until 2008, and the aluminum spent fuel received after that date would be treated using direct co-disposal treatment. ALTERNATIVE COST STUDY In December 1997, Westinghouse Savannah River Company released a report (WSRC, 1997b, hereafter referred to as the "alternative cost study")

From page 85... ...
The alternative cost study provides cost estimates for conventional reprocessing of aluminum spent fuel until about 2010, followed by either direct co-disposal ~eannent, melt and dilute heahnent, or continued reprocessing in a new dedicated facility. 3 DOE is self-regulating and is not required to obtain USNRC licenses for its facilities.

COMPARISON OF TASK TEAM AND ALTERNATIVE COST STUDY ESTIMATES The cost estimates provided by the Task Team and the alternative cost study are not In a strict sense directly comparable because they are based on different sets of planning assumptions and are indexed to different budget periods.s Nevertheless, three general observations that can be made about these estimates for the purpose of a subsequent discussion of the final charge in Me statement of task. The first observation is that We cost estimates provided in the alternative cost study are significantly higher than the estimates in Me Task Team report.

In the alternative cost study, the estimated life-cycle costs of these mature treatment options range from $2,030 million to $2,480 million. At least three hypotheses can be offered to explain the similarity n costs for the mature treatment options: (~)

The answer to the first question the cost estimates account for all of the major cost factors In the aluminum spent fuel treatment program? is "yes." The major cost factors of the system for receiving, treating, handling, storing, and disposing of aluminum spent filet for each of the treatment options were identified in the Task Team report, and systematic cost estimates for these major cost factors were developed in the alternative cost study report.
|
From page 91... ...
The answer to the second question are cost and schedule estimates suitable for comparison of options and selection of one or more preferred alternatives? is a qualified "yes." The cost estimates in both the Task Team report and the alternative cost study appear to be sufficiently complete for comparative purposes and for selecting a small number of alternative treatment options for further consideration.

for the aluminum spent fuel program are released.6 The nonproliferation study currently under way in another part of DOE (Chapter 5) also could significantly impact schedules, budgets, and the selection of treatment options, especially conventional reprocessing.

From page 93... ...
The program has been unable to meet the schedules outlined in the Task Team report, which was published only two years ago, and a number of additional delays of varying significance will no doubt be encountered as the program moves forward. There is no allowance for such delays in either the Task Team report or the alternative cost study, although DOE-Savannah River staff did express sensitivity to these issues at the information-gathering sessions.
