Material unaccounted for performance analysis of a U. S. Nuclear Regulatory Commission licensee. Final report. [Simulation]

MUF and LEMUF performance of a specific facility was modeled. The computer code MCLAMS was used to simulate MUF and LEMUF values for the facility. The simulation results agreed well with the historical MUF and LEMUF performance of the facility. Seven components of MUF were identified for the facility. These components were either measurement- or process-related. There was evidence of human error in the facility data. However, it was not modeled into the MUF performance, because of too little information and the limitations of the current MCLAMS program. From this study, it appears that MUF performance analysis of real-world facilities can be effectively modeled and simulated. Application to additional facilities is recommended.
