Analysis of design practices for snubbers (report 3). [PWR, BWR]

Description: In an effort to understand the expected performance of snubbers, a survey of current design methods was performed. Questionnaires were sent to the major snubber manufacturers requesting information on important phases of snubber analysis, testing, shipping, and handling. The elements of design considered in the questionnaire were derived from an evaluation of snubber failure histories and the performance requirements of snubber users.

CEREN concept: a case study of the French industrial energy data system

Description: A case study of the French CEREN system is provided. The foundation of the system is outlined, that is, the concepts that ensure the systems comprehensiveness, detail, and manageability. The implementation of the system is emphasized, in particular, the data collection and data processing methodology. Applications of the CEREN energy information system are reviewed for analyzing energy use, cross-industry impacts, and social, and economic impacts of changing energy-use patterns. (MHR)

Closed Loop In-Reactor Assembly (CLIRA): a fast flux test facility test vehicle

Description: The Closed Loop In-Reactor Assembly (CLIRA) is a test vehicle for in-core material and fuel experiments in the Fast Flux Test Facility (FFTF). The FFTF is a fast flux nuclear test reactor operated for the Department of Energy (DOE) by Westinghouse Hanford Company in Richland, Washington. The CLIRA is a removable/replaceable part of the Closed Loop System (CLS) which is a sodium coolant system providing flow and temperature control independent of the reactor coolant system. The primary purpose o… more

Exploratory experiments comparing damage effects of high-energy neutrons and fission-reactor neutrons in metals

Description: Until the Rotating-Target Neutron Source II (RTNS II) and the Li(D,n) stripping source for high fluxes of high-energy neutrons are in operation, work related to DMFE's fusion-reactor materials and radiation-effects program is being conducted with lower-flux prototypes, the RTNS I at LLL and a Be(D,n) stripping source at the University of California, Davis. This paper describes these sources and presents results of some exploratory experiments in which 0.5-mm-thick tensile specimens of copper, v… more

Extraction of tritium from liquid lithium by permeation

Description: This paper assesses a method for extracting tritium from liquid lithium for specific application to the conceptual laser fusion reactor that uses a continuous lithium ''waterfall.'' The tritium diffuses through a refractory metal that contains a getter and is then stored in a hydride-forming alloy. There are various uncertainties with this method including helium-4 extraction, unknown impurities that may accumulate in liquid lithium, the effects of these impurities on tritium separation, and th… more

Field-reversed mirror reactor

Description: The reactor design is a multicell arrangement wherein a series of field-reversed plasma layers are arranged along the axis of a long superconducting solenoid which provides the background magnetic field. Normal copper mirror coils and Ioffe bars placed at the first wall radius provide shallow axial and radial magnetic wells for each plasma layer. Each of 11 plasma layers requires the injection of 3.6 MW of 200 keV deuterium and tritium and produces 20 MW of fusion power. The reactor has a net e… more

In-duct countermeasures for reducing fire-generated-smoke-aerosol exposure to HEPA filters. [High efficiency particulate aerosol]

Description: An experimental program was conducted to assess the endurance and lifetime of HEPA filters exposed to fire-generated aerosols, and to reduce the aerosol exposure by installing engineering countermeasures in the duct between the fire source and HEPA filters. Large cribs of wood and other potential fuels of interest were ''forcefully burned'' in a partially ventilated enclosure. In a ''forceful burn'' the crib of fuel is continuously exposed to an energetic premixed methane flame during the entir… more

LOFT CIS Analysis Line 2 inches-IA-298-AB outside containment penetration S-2A

Description: Line 2''-IA-295-AB outside containment penetration S-2A was analyzed to ASME Section III, Subsection NC (Class 2) criteria. The line is part of the Containment Isolation System. The model considered the line from the penetration outward through the first isolation valve. Results of the analysis show that this section of the line meets Class 2 requirements without modification.

LOFT diesel generator ''A'' exhaust stack seismic analysis

Description: A stress analysis of the LOFT Diesel Generator ''A'' Exhaust Stack was performed to determine its reaction to Safe-Shutdown Earthquake loads. The exhaust stack silencer and supporting foundation was found to be inadequate for the postulated seismic accelerations. Lateral support is required to prevent overturning of the silencer pedestal and reinforcement of the 4'' x 0.5'' silencer base straps is necessary. Basic requirements for this additional support are discussed.

LOFT Vital MG Set transient parameter review

Description: This report evaluates the performance of the vital MG sets during a worst case load transfer. Evaluation of test data showed: (1) The Vital MG Set withstood the extreme loading; (2) The load can be sustained well in excess of the required time limit; and (3) The transfer perturbation caused the frequency to exceed the limits set by the SDD. The follow up evaluations of the equipment powered by the MG sets demonstrated that the equipment function will not be degraded.
