摘要

From 1943 through 1986, Battelle Columbus Laboratories (BCL) performed research and development work at its own facilities for the U.S. Department of Energy (DOE) and its predecessor agencies. The most highly contaminated facilities, comprising BCL's Nuclear Sciences Area, are located on 11 acres in West Jefferson, Ohio. Three buildings in this area were used to study nuclear reactor fuels, fuel element components, reactor designs, and radiochemistry analyses: one building contained nuclear hot cells, a second building contained a critical assembly and radiochemistry laboratory, and a third building once housed a nuclear research reactor. The Columbus Environmental Management Project (CEMP), one of the U.S. Department of Energy - Ohio Field Office's radioactive cleanup sites, is responsible for the decontamination and decommissioning (D&D) of BCL's Nuclear Sciences Area. The CEMP mission is to decontaminate the Nuclear Sciences Area to a condition that is suitable for use without restrictions and to dispose of or store the associated radioactive waste at a suitable DOE-approved facility. To ensure the efficiency and effectiveness of this project, the local DOE office requested preparation of a baseline, suitable for independent validation, establishing the cost and schedule for completing this project. This paper presents the results of the systems engineering approach used in the preparation of this baseline. An internal group of D&D subject matter experts participated in the application of a functional analysis technique to determine the specific functions for fulfilling the CEMP mission, the requirements that specify how well the functions must be accomplished, and the preferred technical strategies for accomplishing the functions. Using CORE?, a systems engineering support tool produced by Vitech Corporation, a project model was built that captures the complete set of functions and their relationships, requirements, and strategies. The model was used to track the flow of materials, wastes, samples, and data between functions, ensuring project integration. The D&D subject matter experts also provided cost estimates and durations for individual functions. The functions were then scheduled by level-loading the expenditures over the expected time to complete the entire project. This defined the baseline cost and schedule to completion. The factors that were determined to be most important in achieving independent validation were (1) the use of a systematic, logical process; (2) the development of a comprehensive model for managing functions, requirements, strategies, issues, and risks; and (3) the identification of realistic project risks and contingencies.
