The large-scale interim spent fuel dry storage facilities from nuclear power plantsare planned to start operation by 2010 in Japan. The requirements of these facilities area big spent fuel storage capacity and a restricted site usage close to the boundary. Thesecause a strong request of precise and realistic dose estimation for licensing *** resolve this difficulty three dimensional Monte Carlo calculation methods areintroduced, which is always requested to compare the benchmark experiment of theshielding system for the verification of procedure and statistical errors. Here, two kindsof shielding benchmark experiments;the huge duct streaming and the cask shadowshielding experiments, were newly prepared to get these absent data. As a first step, the huge duct streaming experiment is outlined and the obtainedresults are discussed. Neutron and gamma flux and dose distributions in and around thestreaming duct were measured by moderating type neutron detectors, neutrondosimeters, activation foils, solid state track detectors (CR-39), thermoluminescentdosimeters, glass dosimeters, etc. These results are also compared with the Monte Carlocalculations. Through these procedures the know-how of the spatial dose estimation inand around a huge streaming duct were obtained.

In this paper, a methodology and guidelines for applying risk methods in design and operation of maritime systems were developed and demonstrated using a case study of marine diesel generators. The methodology consists of several modules that include system definition based on functional and performance requirements, definition of dependencies among subsystems, data collection and reduction, reliability and risk analyses, and results reduction for use in decision analysis. The methodology was used to assess and analyze typical service diesel generators found onboard ships. The analysis included the generation of cut sets for the overall reliability of the system. The most likely failure scenarios were determined by demonstration as the failure of fuel supply components. The results are consistent with previous findings of the U.S. Coast Guard.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent Engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

作者： CROUT, AE Timothy J. Doyle:is with the David Taylor Research Center Annapolis Md. He received his BS and MS degrees in mechanical engineering from the City University of New York and Rennsaeler Polytechnic Institute respectively. He worked in electrochemical and turbomachinery development at Pratt and Whitney Aircraft Corporation before joining DTRC in 1966. He served DTRC in various capacities including head of the Electrical Systems Division with cognizance over development programs in ship electric-drives and electrical power generation and distribution systems. In his current position as head of the Power Systems Division Mr. Doyle directs a group of approximately 100 scientists and engineers developing advanced gas turbine engine shaftline and auxiliary systems. Mr. Doyle has authored 18 other papers in ship propulsion and auxiliary machinery areas and is a member of ASME SNAME and ASNE. Guy F. Grater:received a B.S. degree in electrical engineering from the Pennsylvania State University University Park Pa. in 1985. Upon graduation he joined the Propulsion and Auxiliaries Systems Department of the David Taylor Research Center Annapolis Md. where he worked on electrical power system quality and equipment compatibility projects. Presently he is working in the Pulsed Power Systems Office of the Power Systems Division at DTRC developing technologies that will enable shipboard integration of high energy pulsed power systems. He is a member of the IEEE and 1APG.

Alternative power system architectures and interface technologies for driving high energy pulsed loads from the propulsion equipment of surface combatants are compared. Gas turbine mechanical and gas turbine Integrated Electric Drive (IED) propulsion trains are considered as prime power sources. Focus is on the energy path between the ship's prime power and the pulsed load, comparing system candidates on a size, weight and component cost basis. A capacitor based Pulse Forming Network (PFN) supplying an Electro-Thermal (ET) Gun is utilized as the common load for all configurations. Results indicate that dedicated auxiliary generators driven from propulsion gas turbine engines is the preferred method of powering electric gun PFNs from ship drivetrain equipment. Auxiliary generator-based systems are compact and lightweight over a wide power range, are equally attractive with both electric and mechanical drive trains and demonstrate retrofit potential to the current fleet.

ABSTRACT A demonstration submersible outboard electric motor/ propulsor has been designed, built, and successfully tested. This concept involves mounting a propeller directly inside a rotor of a specially designed induction motor. This motor/ propulsor has the advantages of direct seawater cooling and bearing lubrication, direct drive, shrouded propeller, variable positioning, easy access, and high maneuverability. The motor/propulsor is readily adaptable to dual, independently-controlled and contra-rotating propellers without the need for gears. The concept has been investigated conceptually for application to primary propulsion, secondary propulsion, and pod drives, for amphibious, surface, and undersea vehicles.
