Operability test procedure for TRUSAF assayer software upgrade
This OTP is to be used to ensure the operability of the Transuranic Waste Assay System (TRUWAS). The system was upgraded and requires a retest to assure satisfactory operation. The upgrade consists of an AST 486 computer to replace the IBM-PC/XT, and a software upgrade (CNEUT). The software calculations are performed in the same manner as in the previous system (NEUT), however, the new software is written in C Assembly Language. CNEUT is easier to use and far more powerful than the previous program. The TRUWAS is used to verify the TRU content of waste packages sent for storage in the Transuranic Storage and Assay Facility (TRUSAF). The TRUSAF is part of Westinghouse Hanford`s certification program for waste to be shipped to the Waste Isolation Pilot Plant (WIPP) in New Mexico. The Transuranic Waste Assayer uses a combination passive-active neutron interrogation system to determine the TRU content of 55-gallon waste drums. The system consists of a shielded assay chamber; Deuterium-Tritium neutron generator; Helium-3 proportional counters; drum handling system; electronics including preamplifier, amplifier, and discriminator for each of the counter packages; and an AST 486 computer/printer system for data acquisition and analysis. The system can detect down to TRU levels of 10 nCi/g in the waste matrix. The equipment to be tested is: Assay Chamber Door Drum Turntable and Automatic Loading Platform Interlocks Assayer Software; and IBM computer/printer software. The objective of the test is to verify that the system is operational with the AST 486 computer, the software used in the new computer system correctly calculates TRU levels, and the new computer system is capable of storing and retrieving data.
