Review Rejects April MOX Disposition Costs Analysis

By ExchangeMonitor

An external review of The Aerospace Corporation’s recent study of plutonium disposition options rejects Aerospace’s life cycle cost estimates for the Mixed Oxide Fuel Fabrication Facility and a downblending alternative for disposal of surplus plutonium, and projects similar costs for both programs, according to a report released yesterday. The Nuclear Infrastructure Council posted the review, which was ordered by MOX contractor CB&I-AREVA MOX Services and performed by consulting firm High Bridge Associates. The review estimates MOX and plutonium downblending would each cost about $20 billion in future life cycle costs. Incorporating MOX termination and sunk cost estimates would raise the downblending projection to $25 billion, the review summary states. About $4.4 billion has already been spent on building MOX, which is about 65 percent complete, according to CB&I-AREVA MOX Services.

Aerospace’s April report estimated downblending would cost about $17.2 billion. The summary states that High Bridge excluded Aerospace’s bloated “escalation indices” nestled into its $47.5 billion MOX life-cycle cost estimate. “The 4% escalation used by Aerospace is significantly higher than the escalation rates previously directed by NNSA for use on the project (average of 1.4%),” the review summary states. The review repudiates Aerospace’s assessments for several variables as “difficult to follow.” The review states: “Base costs, contingency/risks, funding limits, escalation, and real year (RY) costs [yearly costs adjusted for inflation] for both options were presented in a manner that was difficult to follow. This provided an apparent focus on escalated RY costs.” In its study, Aerospace noted that its MOX estimate included additional life-cycle “to-go” costs.
 
High Bridge performed a “preliminary evaluation” of “risks/contingency base costs excluding escalation,” which include Aerospace risk/contingency cost estimates. The review pegs these “base costs” for MOX and downblending at $24.3 billion and $13 billion, respectively. High Bridge derived its $20 billion MOX and downblending life-cycle estimates by substituting Aerospace’s risk/contingency numbers with its own projections. The review’s $3.7 billion MOX estimate for this cost category is half of Aerospace’s projection, while High Bridge’s $9.3 billion risk/contingency estimate for downblending is $7 billion over Aerospace’s prediction. Fiscal Year 2016 budget documents indicate that the government’s latest estimated cost of MOX is $12.7 billion (which includes D&D and other costs), with $9.1 billion estimated for construction.
