▼ This study focuses on investigation of the RETRAN modeling concepts in the analysis of a safety valve discharge transient. Three safety valve tests conducted at the Combustion Engineering test facility were chosen for evaluation with RETRAN. It was essential to apply the critical flow boundary condition at the downstream nodes of the valve to compute the test results. The results of the RETRAN calculation were compared with the test measurements and the RELAP5/MOD1 computations. Generally, the results were in good agreement qualitatively with the test data and the RELAP5 calculatios. The RETRAN and RELAP5 codes predicted very similar behavior for the transient pressure at various locations in the downstream piping. In the RETRAN evaluations, for steady state initialization of the problems incorporating the heat transfer effect, a small flow rate was maintained in the downstream piping. This was necessary because the test system was initially stagnant, and it was not possible to initialize the steady state solution of the equations of conservation without maintaining a small initial flow prior to the valve opening. The surface temperature of the downstream piping was initially set at 212 F. This was higher than the test condition temperature (80 F) and it limited condensation in the system, which led to overestimation of the RETRAN-calculated pressure in downstream of the piping compared to the test data and RELAP5 evaluations. Also, RETRAN predicted that changes in the system were faster-acting than what the test data showed or the RELAP5 computations predicted. This was due to the application of choked flow boundary conditions at the downstream junctions. In this case, the friction and local losses effects were absent from the calculations, making the system of equations underdamped. To examine the applicability of the critical flow boundary condition in the computations and the general behavior of the RETRAN homogeneous flow model for this special problem, the basic models pertinent to the RETRAN calculations were examined. Approximations were made to simplify the models which were then verified against the RETRAN results. A computer program (PIERAN) was developed utilizing the approximated models in an effort to determine the nature of the instabilities in the calculation attributed to the homogeneous flow model. PIERAN was used to investigate the flow model behavior for the problem of a valve discharge into a straight pipe. Several runs were made with PIERAN to investigate the effect of the time step size and the volume length along the downstream piping. The results showed instability in the calculation when larger number of volumes were used in downstream of the valve. The instability, however, did not occur for a single volume in the downstream segment of the pipe throughout the calculation. Advisors/Committee Members: Ringle, John C. (advisor).

▼ The determinants of electrical energy demand for the State of Oregon are represented in a mathematical model. This model is structured to operate in parallel with a computer simulation model of the state and is utilized independently to investigate electrical energy consumption during various scenarios of economic activity and energy prices. The introductory chapters discuss the importance of the inclusion into energy forecasts of the effects of significant changes in economic and demographic variables as well as consumer responses to increasing energy prices. Alternate methodologies used in forecasting are reviewed. It is argued that the determinants of electricity demand should be viewed as interrelated elements of a socio-economic system and must be addressed in concert with one another. The Oregon State Simulation Model (OSSIM) and the system simulation methodology employed in its development are described. Chapter four presents the data base, structure, and dynamics of the electrical energy demand model. Intensiveness of electricity use and economic activity are exhibited separately, to demonstrate whether increases in consumption are due to changes in intensiveness, to economic growth, or to both and in what proportion. Increasing energy prices induce electricity conservation, interfuel substitution, and changes in appliance saturation trends. These phenomena are modeled explicitly, recognizing that each can affect intensiveness of use and can be characterized by different time constants and limits. The following four chapters develop electrical energy intensiveness functions for thirty-seven consumer categories which are divided among four major sectors. The industrial sector consists of nineteen two-digit SIC groups and three irrigation regions; twelve household appliances and one residual group are included in the residential sector; the commercial sector covers all service activities with the exception of street/highway illumination, which composes the transportation sector. Underlying causes of changing electrical energy intensiveness are explored and price-independent projections of intensiveness are proposed. These projections are linear functions of time in the non-residential categories and sigmoidal functions in twelve residential categories. Results of model operation with exogenous functions of economic activity are discussed in the concluding chapter, together with a description of sensitivity testing and validation criteria. Scenarios investigated demonstrate the significance of the detailed representation of consumer responses to energy price changes. Model utility appears to lie in the ability to illustrate causes of changes in electricity consumption growth rate, to assess alternate scenarios of energy prices, and – when utilized in concert with the OSSIM – to estimate electrical energy requirements based upon self-consistent scenarios of underlying economic activity.
