  • Input-output modeling is now being used to assess systemwide occupational and public health and safety risks of energy technologies. Some of the advantages and disadvantages of this method are presented, and some of its important limitations discussed. Its primary advantage is that it provides a standard method with which to compare technologies on a consistent basis without extensive economic analysis. Among the disadvantages are limited range of applicability, limited spectrum of health impacts included, and inability to identify unusual health impacts unique to a new technology. The units in which risk assessments should be expressed and the differences in interpretationmore » that can result from use of different units are also discussed.« less
  • Renewable energy sources have a broad range of total systemwide occupational health and safety impacts, but a relatively narrow range of average risk to individual workers. Nearly all of the renewable energy sources studied have greater total systemwide impacts than a representative coal fuel cycle. This reflects a greater energy and labor intensity per unit energy delivered. Roughly half of the renewable energy sources, however, have lower average risk to individual workers. Central station photovoltaics and passive solar heating stand alone as the least risky of the technologies examined, with respect to both total systemwide risk and average individual risk.more » Residential wind with no storage and wood pyrolysis are the riskiest. Considerable caution must be exercised in using these results to compare relative impacts of renewable energy sources. They neither produce the same end form of energy nor are they directly substitutable one for another. The results present here should, therefore, be taken as only indicators of potential differences.« less
  • In order to assist DOE in prioritizing, developing, and commercializing storage technologies, a computer simulation code was developed to assess the impact of alternative residential heating and cooling technologies upon electric utility generation, transmission, and distribution systems. Given input information such as plant capacity, forced-outage rates, scheduled maintenance requirements, and economic data for individual generating units, the program uses hourly utility load data together with synoptic weather data to simulate system loads and costs for specified levels of heating/cooling technology penetration. The program performs five categories of calculations: simulation of residential load, aggregation and propagation of loads through the distributionmore » and transmission subsystems, economic dispatch of generating plant, scheduling of plant maintenance, and calculation of optimal generating plant mix. Originally designed to study the impact of shifting on-peak demand to off-peak periods through the use of customer-owned thermal storage, the code has been extended to handle a variety of electric heating and cooling technologies. Results are presented for residential space-conditioning systems for two representative utility-service areas. In the service area supplied by a winter-peaking utility, the lowest-cost space-heating technologies were found to be storage-augmented either by storage or by an oil furnace.Heat pumps were the most economical heating systems in the service area supplied by the summer-peaking utility while storage air conditioning was cost-effective for cooling in the summer-peaking service area.« less
  • Many advanced light water reactor designs incorporate passive rather than active safety features for front-line accident response. A method for evaluating the reliability of these passive systems in the context of probabilistic risk assessment has been developed at Sandia National Laboratories. This method addresses both the component (e.g. valve) failure aspect of passive system failure, and uncertainties in system success criteria arising from uncertainties in the system's underlying physical processes. These processes provide the system's driving force; examples are natural circulation and gravity-induced injection. This paper describes the method, and provides some preliminary results of application of the approach tomore » the Westinghouse AP600 design.« less
