Title: A Critical Examination of Figure of Merit (FOM). Assessing the Goodness-of-Fit in Gamma/X-ray Peak Analysis

Abstract

In this paper we develop and investigate several criteria for assessing how well a proposed spectral form fits observed spectra. We consider the classical improved figure of merit (FOM) along with several modifications, as well as criteria motivated by Poisson regression from the statistical literature. We also develop a new FOM that is based on the statistical idea of the bootstrap. A spectral simulator has been developed to assess the performance of these different criteria under multiple data configurations.

  • Ten systems potentially applicable to the processing of TRU wastes at INEL were evaluated. The three candidates found to be superior to the rest were: (1) a system with two parallel slagging pyrolysis incinerators, each with a capacity of about 70,000 kg/d (kilograms per day), (2) a system with a single slagging pyrolysis incinerator with a capacity of 200,000 kg/d, and (3) a system with an indirect-fired rotary kiln incinerator. The differences in performance evaluations among the top three systems were minor, and the preliminary design work on each of the three should continue. For use in this final choice,more » the preparation of a preliminary safety analysis review (PSAR) should begin immediately. Because of a general lack of radwaste processing experience and a total lack at the scale necessary at INEL, a substantial research and development program is necessary no matter which type of incinerator system is ultimately selected. Since the choice of a processing system could easily be altered by more reliable information, the construction and operation of a pilot plant is recommended for generating more data, not only for the final design of the facility at INEL but also for improving the body of knowledge in radwaste processing. In addition to the need for demonstrated technology, four constraints weigh heavily on the processing problem at INEL. One is that the waste acceptance criteria for the Waste Isolation Pilot Plant have not been finalized. Another constraint is that with current technology there is no way to assay the TRU material in the waste at the levels and rates required. A third constraint is that the processing of all waste with a contamination level as low as 10 nCi/g is unrealistic in the judgment of the task force. The fourth constraint is that no decision has been made as to whether the facility construction must meet DOE Manual Chapter 6301, Part I or Part II.« less
  • The purpose of this paper is to provide guidelines for assessing the performance of actively cooled high-power/high-energy laser beam (HEL) reflectors. The first segment concerns a highly simplified situation involving steady-state irradiance-mapping distortions only a comprehensive 'mirror figure of merit' may thus be defined for characterizing the performance of HEL reflectors, in the absence of pressure-induced ripples. In the second part, a generalized mirror/heat-exchanger model is used for evaluating the potential impact of coolant-induced distortions, for identifying key properties of mirror materials, and for creating a 'material index of goodness' applicable to HEL reflectors. The most promising candidates are siliconmore » carbide and tungsten.« less
  • The accuracy of the calculational techniques used for routine predictions of test fuel power levels in the PBF is investigated by comparing flux-wire activation and direct fission density measurements obtained during selected PBF experiments with corresponding calculated results generated using standard PBF reactor physics calculational models. It is concluded from the three tests examined that in some cases the standard calculational methods can tend to systematically overpredict test fuel powers by as much as, but in all probability no more than, approximately 12%.
