Book excerpt: This thesis is concerned with development of methods for optimizing the energy production and refuelling decision for nuclear power plants in an electric utility system containing both nuclear and fossil-fuelled stations. The objective is to minimize the revenue requirements for refuelling the power plants during the planning horizon; the decision variables are the energy generation, reload enrichment and batch fraction for each reactor cycle; the constraints are that the customer's load demand, as well as various other operational and engineering requirements be satisfied. This problem can be decomposed into two sub-problems. The first sub-problem is concerned with scheduling energy between nuclear reactors which have been fuelled in an optimal fashion. The second sub-problem is concerned with optimizing the fuelling of nuclear reactors given an optimized energy schedule. These two sub-problems when solved iteratively and interactively, would yield an optimal solution to the original problem. The problem of optimal energy scheduling between nuclear reactors can be formulated as a linear program. The incremental cost of energy is required as input to the linear program. Three methods of calculating incremental cost are considered: the Rigorous Method, based on the definition of partial derivativesis accurate but time consuring; the Inventory Value Method and the Linearization Method, based respectively on equations of inventory evaluation and linearization, are less accurate, but efficient. The latter two methods are recommended for the early stages of optimization. The problem of optimizing the fuelling of nuclear reactors has been solved for two cases: the special case of steady state operation, and the general case of nonsteady- state operation. The steady-state case has been solved by simple graphic techniques. The results indicate that reactors should be refuelled with as small a batch fraction as allowed by burnup constraints. The non-steady case has been solved by polynomial approximation, in which the objective function as well as the constraints are approximated by a sum of polynomials. The results indicate that the final selection of an optimal solution from a set of sub-optimal solutions is primarily based on engineering considerations, and not on economics considerations.

This book was released on 1973 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: A nuclear power management model suitable for nuclear utility systems optimization has been developed for use in multi-reactor fuel management planning over periods of up to ten years. The overall utility planning model consists of four sub-models: (1) Refueling and Maintenance Model (RAMM), (2) System Integration Model (SIM), (3) System Optimization Model (SOM), and (4) CORE Simulation and Optimization Models (CORSOM's). The SIM and SOM sub-models were developed in this study and are discussed in detail; full-scale computerized versions of each (SYSINT and SYSOPT, respectively) are evaluated as part of the methods development research. The RAMM generates feasible, mutually exclusive nuclear refueling-fossil maintenance schedules. These are evaluated in detail by the rest of the model. Using the Booth-Baleriaux probabilistic utility system model, the SIM integrates the characteristics of the utility's plants into a representation which meets the necessary operating constraints. Scheduling of system nuclear production and detailed fossil production is done for each time period (few weeks) making up the multi-year planning horizon. Utilizing a network programming model, the SOM optimizes the detailed production schedules of the nuclear units so as to produce the required system nuclear energy at minimum system cost. CORSOM's are utilized to optimize reload parameters (batch size and enrichment) and to generate the individual reactor fuel costs and nuclear incremental costs. These incremental costs are then used by the SOM's iterative gradient optimization technique known as the method of convex combinations. The SYSINT model is shown to be remarkably fast, performing the Booth-Baleriaux simulation for a single time period on a system with over 45 generating units in less than 2.5 seconds on an IBM-370 model 155 computer. SYSOPT converged to optimum solutions in roughly ten iterations. Immediate reduction of iterations by roughly half is estimated by merely increasing piecewise-linearization of the network objective function. Overall model computational requirements are limited by available CORSOM's, which require 99% of the computational effort (over 3 minutes per reactor per SOM iteration). Nuclear incremental costs (~ 0.8-1.6 $/MWH) are shown to be less than fossil incremental costs (> 2.0 $/MWH) for the foreseeable future. Thus, nuclear power should always be operated so as to supply customer demands with a minimum use of the more expensive fossil energy. For the same reason, the lengthening of nuclear irradiation cycles (in terms of both energy and time) more than pays for itself by reducing the total cost of fossil replacement energy. Idealized nuclear production schedules yield constant nuclear incremental costs regardless of reactor unit and time. One of the key input parameters is the fossil thermal energy cost.
Book Synopsis Integrated Approach to Optimize Operation and Maintenance Costs for Operrating Nuclear Power Plants by : International Atomic Energy Agency
Download or read book Integrated Approach to Optimize Operation and Maintenance Costs for Operrating Nuclear Power Plants written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasingly competitive environment of the electricity sector has significant implications for nuclear power plant (NPP) operations. Management objectives must be focused on efficient operation as the key to profitability. The business and financial success of operating NPPs must be given greater consideration through an integrated approach which also ensures the successful achievement of safety and reliability objectives. In developing strategic and operational goals, nuclear plant managers will be required to embrace and articulate clear and measurable business objectives and goals which not only assure the achievement of safety and reliability but also eliminate unnecessary costs and identify investment opportunities. This publication looks at the optimization of the costs as an integrated part of the management of organization business process with a focus on planning (strategic and tactical) and on controlling (control system, corrective actions and pay reward) functions.--Publisher's description.

This book was released on 2021-10-28 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental Issues Critical to the Success of Nuclear Projects presents a complete analysis of the core considerations for those deploying nuclear power plants, managing existing plants, and also for those developing and building new plants. It includes critical considerations, such as cost-estimation, safety procedures, and regulatory compliance, manpower optimization and development, and the application of innovative technologies, such as the use of robotics. Those important issues have been addressed in a systematic way, and explanations have been provided on how the nuclear industry has continuously found solutions to mitigate and eventually solve them properly. Discusses innovative technologies being implemented in international nuclear plants to improve efficiency, safety, and cost-effectiveness in new, existing, and decommissioned nuclear power plants Provides guidance on difficult cost estimation for nuclear projects, as well as safety procedures, legislation, and regulatory compliance both inside and outside of the United States Considers the future of nuclear energy and analyses the challenges ahead for a sustainable nuclear energy future
