Title: Design Options to Reduce Development Cost of First Generation Surface Reactors

Abstract

Low-power surface reactors have the potential to have the lowest development cost of any space reactor application, primarily because system alpha (mass/kg) is not of utmost importance and mission lifetimes do not have to be a decade or more. Even then, the development cost of a surface reactor can vary substantially depending on the performance requirements (e.g. mass, power, lifetime, reliability) and technical development risk deemed acceptable by the end-user. It is important for potential users to be aware of these relationships before they determine their future architecture (i.e. decide what they need). Generally, the greatest potential costs of a space reactor program are a nuclear-powered ground test and extensive material development campaigns, so it is important to consider options that can minimize the need for or complexity of such tasks. The intended goal of this paper is to inform potential surface reactor users of the potential sensitivities of surface reactor development cost to design requirements, and areas where technical risk can be traded with development cost.

  • Heat exchanger design is a complex task involving the selection of a large number of interdependent design parameters. There are no established general techniques for optimizing the design, though a few earlier attempts provide computer software based on gradient methods, case study methods, etc. The authors felt that it would be useful to determine the nature of the optimal and near-optimal feasible designs to devise an optimization technique. Therefore, in this article they have obtained a large number of feasible designs of shell and tube heat exchangers, intended to perform a given heat duty, by an exhaustive search method. Theymore » have studied how their capital and operating costs varied. The study reveals several interesting aspects of the dependence of capital and total costs on various design parameters. The authors considered a typical shell and tube heat exchanger used in an oil refinery. Its heat duty, inlet temperature and other details are given.« less
  • The price difference between US conventional and reformulated gasolines is expected to be 3.1[cents]/gal higher, less than the 4[cents]/gal difference indicated in May by the New York Mercantile Exchange. The difference will be set by the central Atlantic and New England areas, which Bonner Moore projects to be significantly short on reformulated gasoline and long on conventional gasoline. Bonner Moore consultants, in an unpublished report, say refiners in the central Atlantic will not be able to economically convert much more than 70% of their gasoline output to reformulated gasoline. As a result, gasoline movements through the pipeline system supplying Petroleummore » Administration for Defense District (PADD) 1-the US East Coast-will have to increase to deliver reformulated gasoline produced on the Gulf Coast to New England and the Central Atlantic region. The paper discusses production costs, processing options, price differential, compliance, and benefits from averaging both oxygen and benzene parameters.« less
  • A set of rapid assessment charts which offer industrial management an opportunity to analyze the performance of various cogeneration plant options has been developed. They allow management to graphically assess the ability of a topping plant to match process demands (power and/or heat) and pay for itself within an acceptable payback period. Apart from rank-ordering, the charts permit an evaluation of the relationship between the prevailing cost structure for source energy and the economic merits of the plant - and the effect of cost changes.
  • Safety options for surface reactors of less than 800 kW (thermal power) are analyzed. The concepts under consideration are heat pipe cooled reactors fueled with either uranium nitride or uranium dioxide. This study investigates the impact of launch accident criteria on the system mass, while ensuring the mechanical integrity and reliability of the system through launch accident scenarios. The four criticality scenarios analyzed for shutdown determination are dry sand surround with reflectors stripped, water submersion on concrete, water submersion with all control drums in, and the nominal shutdown reactor condition. Additionally the following two operational criteria are analyzed: reactor ismore » warm and swelled, and reactor is warm and swelled with one drum in (where swelled includes both thermal mechanical expansion and irradiation induced swelling of the fuel)« less
