  • The steady-state temperature distribution and the stored energy in nuclear fuel elements are computed by analytical methods and used to rank, in the order of importance, the effects on stored energy from statistical uncertainties in modeling parameters, in boundary and in operating conditions. An integral technique is used to calculate the transient fuel temperature and to estimate the uncertainties in predicting the fuel thermal response and the peak clad temperature during a large-break loss of coolant accident. The uncertainty analysis presented here is an important part of evaluating the applicability, the uncertainties and the scaling capabilities of computer codes formore » nuclear reactor safety analyses. The methods employed in this analysis merit general attention because of their simplicity. It is shown that the blowdown peak is dominated by fuel stored energy alone or, equivalently, by linear heating rate. Gap conductance, peaking factors and fuel thermal conductivity are the three most important fuel modeling parameters affecting peak clad temperature uncertainty. 26 refs., 10 figs., 6 tabs.« less
  • In order to evaluate and compare the overall greenhouse warming of application-specific, alternative CFC solvent cleaning systems including not in kind options, it is necessary to consider both the direct and the indirect contributions which are due, respectively, to the emission of the solvent vapor, and to the CO{sub 2} emissions resulting from the energy required to operate the system over its normal lifetime. The Total Energy Warming Impact (TEWI) is defined as the sum of these factors. In a joint industry/government effort co-funded by the Alternative Fluorocarbons Acceptability Study (AFEAS) and the U.S. Department of Energy (DOE), this studymore » has been carried with solvent cleaning systems, as well as for refrigeration, air conditioning and foam blowing applications. Cleaning options considered include organic solvents such as hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), chlorinated and oxygenated hydrocarbons, aqueous and semi-aqueous systems; and {open_quotes}no clean{close_quotes} technologies. Along with the TEWI, other factors to consider when choosing an alternative CFC solvent system include: cleaning efficiency worker safety, toxicity, operating costs, investment, floor space, energy efficiency, reliability; and environmental issues such as discharge to sewers and waterways, and air quality.« less
