Multimegawatt space nuclear power supply: Phase 1, Final report

Description: The preliminary safety assessment report analyzes the potential radiological risk of the integrated MSNPS with the launch vehicle including interface with the weapon system. Most emphasis will be placed the prime power concept design. Safety problems can occur any time during the entire life cycle of the system including contingency phases. The preliminary safety assessment report is to be delivered at the end of phase 2. This assessment will be the basis of the safety requirements which will b… more

Multimegawatt space nuclear power supply: Phase 1, Final report

Description: The Phase 2 program objectives are to (1) demonstrate concept feasibility, (2) develop a preliminary design, and (3) complete Phase 3 engineering development and ground test plans. The approach to accomplish these objectives is to prove technical feasibility of our baseline design early in the program while maintaining flexibility to easily respond to changing requirements and advances in technology. This approach recognizes that technology is advancing rapidly while the operational phase MSNPS… more

US/Japan collaborative program on fusion reactor materials: Summary of the tenth DOE/JAERI Annex I technical progress meeting on neutron irradiation effects in first wall and blanket structural materials

Description: This meeting was held at Oak Ridge National Laboratory on March 17, 1989, to review the technical progress on the collaborative DOE/JAERI program on fusion reactor materials. The purpose of the program is to determine the effects of neutron irradiation on the mechanical behavior and dimensional stability of US and Japanese austenitic stainless steels. Phase I of the program focused on the effects of high concentrations of helium on the tensile, fatigue, and swelling properties of both US and Ja… more

Pre-Amp Box Platform Analysis

Description: A platform to be used for the installation and repair of the high voltage pre-amp boxes on the CC cryostat has been designed to support a uniform load of 30 Ibs./sq. ft. However, according to the standards set by both the American National Standard and the Uniform Building Code, the minimum uniformly distributed design load for a structure used as an 'elevated platform or walkway' is 60 lbs./sq. ft. The existing platform was tested with a uniform load of 40 lbs./sq. ft. with no major problems o… more

[Studies on the interaction of blood components with ultra-smooth polymer surfaces]

Description: This report is in three parts, though each is briefly described data is provided. The three parts address (1) radioiodination of human thrombin and fibrinogen; (2) interaction of blood components with ultra- smooth polymer surfaces; and (3) initial studies of Tecoflex and treated Tecoflex cups with normal serum samples.

Multimegawatt space nuclear power supply, Phase 1 Final report

Description: This Specification establishes the performance, design, development, and test requirements for the Boeing Multimegawatt Space Nuclear Power System (MSNPS). The Boeing Multimegawatt Space Power System is part of the DOE/SDIO Multimegawatt Space Nuclear Power Program. The purpose of this program is to provide a space-based nuclear power system to meet the needs of SDIO missions. The Boeing MSNPS is a category 1 concept which is capable of delivering 10's of MW(e) for 100's of seconds with effluen… more

Interaction of carbon and sulfur on metal catalysts: Technical progress report

Description: At high coverage, sulfur generally deactivates metal catalysts, but at low coverage, chemisorbed sulfur can have a more subtle effect on catalyst activity and selectivity. The general goal of the current project is to examine fundamental aspects of selective poisoning by fractional monolayers of chemisorbed sulfur on a variety of metal catalysts used for commercially important reactions such as hydrocarbon re-forming, light alkane steam re-forming, and hydrocarbon synthesis. Specific objectives… more

Molecular detection using Rydberg, autoionizing, and cluster states. Progress report

Description: Continuing investigations of multiphoton ionization processes in naphthalene have established the geometry and spectroscopy of trimer and tetramer cluster states. A new, highly efficient ionization mechanism has been identified in the trimer. It is closely related to autoionization of 2-electron atoms by resonant 2-photon excitation and to exciton fusion in larger clusters.

Geothermal evaluation and analysis of the Yucca Mountain Repository, Nevada; Final report, July 1, 1989--December 31, 1989

Description: This is the final report on the geothermal analysis and evaluation for the proposed nuclear waste repository at Yucca Mountain, for the period of July 1, 1989 to December 31, 1989. Heat flow values were derived by measuring the thermal conductivities of samples taken from selected exploratory wells. Temperature gradients are recorded from the same wells. By using computer generated contour maps of the area, another interpretation of the heat-flow can be derived. Results of the mapping do not co… more

Program status 3. quarter -- FY 1989: Fusion technology development

Description: The cold support concept for the ARIES TF coil design was developed further. This concept not only works for aspect ratio 6 and 4.5 machines, but it also works for ITER. Beryllium was added to the two blanket concepts to improve energy multiplication and reduce COE. During the quarter a US-Japan steering committee meeting was held to discuss the US-Japan ICRH tube tests. They reviewed and approved the proposed X2242 ICRH tube improvements. Ed Cheng attended IAEA meeting on the International Fus… more
