Title: A Next-Generation Automated Holdup Measurement System (HMS-5)

Abstract

Holdup Measurement System 4 software (HMS4) has been in use at facilities to systematically measure and verify the amounts of uranium holdup in process facilities under safeguards since its release in 2004. It is a system for measuring uranium and plutonium and archiving holdup data (via barcoded locations with information) which is essential for any internationally safeguarded facility to monitor all amounts of residual special nuclear material (SNM). Additionally, HMS4 has been tested by sites in Russia, the United States, South Africa, and China for more effective application. Comments and lessons learned have been received over time and an updated version of the software would enable the international partners to use a wider variety of commercial equipment existing at these facilities. In June 2005, the Oak Ridge National Laboratory (ORNL) and Los Alamos National Laboratory conducted a holdup measurement training course on HMS4 for subject matter experts from the Ulba Metallurgical Facility at Ust-Kamenogorsk, Kazakhstan, which included an additional external software package for improved measurements of low-enriched uranium by using higher energy gamma-rays more readily found. Due to not being currently integrated into HMS4, it would be greatly beneficial to include this application in the next generation HMS software packagemore » (HMS-5). This software system upgrade would assist the International Atomic Energy Agency (IAEA) in having a more comprehensive software package and having it tested at several safeguarded locations. When released, HMS4 only supported AMETEK/ORTEC equipment despite many facilities currently utilizing Canberra Industries technology (detectors, multi-channel analyzers, other hardware, and software packages). For HMS-5 to support all available hardware systems and to benefit the majority of international partners and the IAEA, Canberra technology must be integrated because of such widespread use of its hardware. Furthermore, newly developed hardware such as lanthanum halide detectors and digital processing multichannel analyzers will be incorporated into the new HMS-5 system to accommodate the evolving realm of SNM detection and quantification. HMS-5 is the natural progression from the previous incantations of automated special nuclear material holdup measurement systems for process facilities. ORNL is leading this next-generation system with assistance from its foreign partners and past experiences of its Safeguards Laboratory staff.« less

  • The gain of a portable low resolution BGO detector-PMCA (Portable Multi-Channel Analyzer) measurement system, used to make holdup measurements in a manufacturing plant environment, is sensitive to fluctuations in ambient temperature. To ensure reliable measurements in the field, operators had to periodically measure a standard radioactive source and manually adjust the gain to meet established acceptable criteria. Failure to meet the measurement control criteria resulted in repeating all measurements acquired since the previous acceptable measurement control check. An automatic temperature compensation system was developed by characterizing the PMCA gain response as a function of temperature and establishing a software-controlled temperaturemore » compensation program. A voltage-independent temperature transducer is mounted in the BGO probe. Prior to taking an actual measurement, the software checks the temperature of the probe sensor and adjusts the PMCA gain according to the response curve. The frequency of periodic gain checks is reduced, which reduces the overall measurement time. Measurement control failures have almost been eliminated, reducing the need to make repeat measurements. The apparent significant improvement in measurement precision will be verified by future studies. The measurement system can be used over the temperature range of 0 to 40 C.« less
