Decommissioning Cost Information from the Massachusetts Institute of Technology Research Reactor Facility Docket 50-20 License No. R-37 Submitted 10/11/2006
/ Duke Engineering E& Services.
ADukeEwVrjhvaV EXECUTIVE
SUMMARY
Massachusetts Institute of Technology (MM) contracted Duke Engineering and Services (DE&S) to perform an update of the decommissioning cost estimate (DOE) for the MITR-H research reactor facility.
The report fulfills the following requirements ofthe agreement between DE&S and MIT:
- Work Breakdown Structure (WBS) ofthe entire project Project schedule Project cost and resource estimates Summary Report The MITr-H DCE is not an update ofthe 1989 Conceptual Decommissioning Plan and Cost Estimates, provided by General Electric Nuclear Energy. Instead, the MITR-1 DCE is a "bottoms-up" cost estimate that uses current industry experience and bid preparation practices. The cost estimate physical inventory is developed from site walk-downs and data gathering, combined with material take-off compiled from the data acquisition activities. Using proven cost estimating techniques and employing the aide of industry professionals, as well as expertise from the MIT research team, the cost estimate, including contingency, is reliable to within +/-25% of actual expected decommissioning cost expenditures.
Depending on the timing and the manner in which the decommissioning project is managed, the expected cost ofthe overall decommissioning may be 25% lower than that reported herein, or 25% greater than that reported.
The resulting DCE is the result of a team approach to estimating the current cost to decomnission MITR-IL The MIT Nuclear Reactor Laboratory provided technical support to DE&S throughout the cost estimating process. The team met on four separate occasions throughout the ten-week duration ofthe project. MIT staffprovided DE&S with over two hundred drawingi ofthe facility as well as financial operating costs, essential to the complete accounting of all expected costs for the future decommissioning of the facility. The team conducted a number of site walk-downs and photographed 'all accessible areas.
MIT provided the team with photographs of inaccessible areas that also proved to be useful in developing the inventory for the DCE.
The DCE provides MIT with a baseline estimate to use for the eventual decommissioning planning and execution. By no means does this report sugges MIT's strategy on decommissioning MITR-IT nor does it represent a fixed price bid for contracted activities. The study represents one probable decommissioning scenario considering the current physical state of the facility.
The DCE for MITR-II is expected to take approximately five years to complete. A project schedule is presented in the backup material for this report A number of inefficiencies are built into the schedule to reflect periods of inactivity while waiting for both NRC approval of the decommissioning plan, and MIT's anticipated effort to offload fuel from the site. The actual hands-on portion of the decommissioning is estimated to take approximately one year, with a one-year pre-planning period and eighteen months of final status survey and facility closeout. The estimated cost to decommission MMTR-I, in mid-year 2001 dollars is $20.9 million, without contingency. Based on the conservatism that is built into the DCE, a contingency of 10% shouldbe appliedto this~baseline estimate for a total DO-E of $23.0 million.
