Application of a Life-Cycle Model to Evaluate FutureSustainability Costs for MPCA Upgrades at the All RussianScientific Research Institute of Experimental Physics (VNIIEF)

摘要

This paper presents the application of a Life-Cycle-Cost (LCC) Decision Support Systemrn[1] to evaluate the future costs of Material Protection Control and Accounting (MPC&A)rnupgrades being implemented at the All-Russian Scientific Research Institute ofrnExperimental Physics (VNIIEF). The life-cycle costing model captures fixed, fixedvariable,rnand variable cost elements. These costs are associated with acquisition,rndisposition, management, initial, and ongoing training of equipment maintenance andrnoperations staff, operations, maintenance, and testing.rnA structure is developed, and systematic LCC analysis is performed to show the differentrncosts for the major components of upgraded MPC&A systems, for each system as arnwhole, for multiple systems within a building, within a guarded area (GA), and acrossrnmultiple Gas. The analysis also shows the cost variations for different choices ofrnmaintenance, training, and management strategies for the upgrades in the long term. Arnpotential use of the analysis is to show the impact of alternative long-term maintenancernstrategies (vendor supported vs. site supported) for multiple out-years (I.e. beyond therncurrent year) and different inflation rates.rnAlthough the emphasis of the paper is on VNIIEF upgrades, the model, cost templates,rnand analysis approach presented are also applicable to transportation, protective forces,rnand other site-level MPC&A systems. Site teams should be able to use this approach andrnmodel to assess costs for sustaining MPC&A upgrades at individual sites and acrossrnmultiple sites. LCC analysis may also be used to analyze the impact of obsolescence onrnsystem cost, replacement policy, and part-stocking requirements.
