This report describes how constraints imposed by the physical principles of the various assay techniques, by the potential user and by the industrial environment have been accounted for in the design and construction of the Continuous On-line Coal Analyzer of Coal--CONAC. The report describes the overall instrument requirements for accuracy and precision in the determination of the elemental constituents of the coal along with its moisture, ash and calorific value. How these and other design requirements are met for each of the CONAC subsystems are also described. These subsystems embody the various non-intrusive assay techniques incorporated in the CONAC, including prompt gamma neutron activation analysis (PGNAA), microwave moisture monitoring, gamma ray densitometry, and hydrogen monitoring by neutron moderation. Other subsystems of the CONAC described in this report include the radioactive source-shielding system, the coal conveyance system, the data acquisition system, and the software operator interface. The general mechanical and electrical specifications for the CONAC are also included. 7 references, 19 figures, 5 tables.
