Core-power and decay-time limits for disabled automatic-actuation of LOFT ECCS

Description: The Emergency Core Cooling System (ECCS) for the LOFT reactor may need to be disabled for modifications or repairs of hardware or instrumentation or for component testing during periods when the reactor system is hot and pressurized, or it may be desirable to enable the ECCS to be disabled without the necessity of cooling down and depressurizing the reactor. A policy involves disabling the automatic-actuation of the LOFT ECCS, but still retaining the manual actuation capability. Disabling of th… more

HEAL G-C ICES, Phase II: detailed feasibility analysis and preliminary design. Final report, Stage 1

Description: In this preliminary report for Phase II of Health Education Authority of Louisiana's (HEAL) ICES program, specific elements of the basic intitutional issues were readdressed, as requested by the U.S. Department of Energy. The draft environmental assessment was reassessed and updated. Thermal energy demand profiles for the major community sectors, i.e., the five institutions comprising the HEAL Complex, were refined on a month-by-month basis and resulted in establishing ICES plant systems design… more

Analysis of the Powder Diffraction File

Description: The International Centre for Powder Diffraction Data has compiled an extensive powder diffraction database available on magnetic tape. The database was evaluated to determine the type and quality of the information it contains, including an analysis of d-I pairs per pattern, symmetry, quality marks, Q values, and intensities for subfiles of known crystal class. In addition, nine functions were evaluated to assess pattern quality for cubic and triclinic data. This document presents a minimum amo… more

Reference design for the standard mirror hybrid reactor

Description: This report describes the results of a two-year study by Lawrence Livermore Laboratory and General Atomic Co. to develop a conceptual design for the standard (minimum-B) mirror hybrid reactor. The reactor parameters have been chosen to minimize the cost of producing nuclear fuel (/sup 239/Pu) for consumption in fission power reactors (light water reactors). The deuterium-tritium plasma produces approximately 400 MW of fusion power with a plasma Q of 0.64. The fast-fission blanket, which is fuel… more

Grid-connected integrated community energy system. Phase II, Stage 2, final report. Executive summary

Description: The University of Minnesota Grid-ICES was divided into four identifiable programs in order to study the feasibility of each of the parts of the ICES independently. The total program involves cogeneration, fuel conversion, fuel substitution, and energy conservation by system change. This Phase II report substantiates the theory that the Basic Grid ICES is not only energy-effective, but it will become cost effective as unit operating costs adjust to supply and demand in the 1980's. The Basic Prog… more
