Analysis of ICPP process-monitoring-system data collected during August-October, 1981

As part of the FY-1982 advanced safeguards development program, selected process data collected during August-October 1981 by the ICPP Process Monitoring Computer System (PMCS) were analyzed. This analysis is the first major effort of its kind using data from this VAX 11/780 computer based system. These data were from the first, second, and third processing cycles. Several process events were identified and isolated for analysis to conserve limited program resources. These included process input (G-Cell) batch transfers, continuous first-cycle feed activities, transfers into N-Cell intercycle storage, and continuous second-cycle feed activities. The analyses principally used Scanivalve plant precision data from tank bubbler probes, temperature data, and plant digital data. Some useful assessments are given to the process data information, but they should be considered preliminary since not all collected data could be analyzed. Also, several data limitations are noted and recommendations are given for system improvements. It is believed that this analysis effort demonstrates the potential utility of the system for improved safeguards applications; yet, further, similar analysis efforts are needed to extend and complete a demonstration to characterize ICPP process data in general.
