Experimental facilities

Description: We have completed an engineering feasibility study of a major modification of the HFIR facility and are now beginning a similar study of an entirely new facility. The design of the reactor itself is common to both options. In this paper, a general description of the modified HFIR is presented with some indications of the additional facilities that might be available in an entirely new facility.

Tensile properties and swelling of 20%-cold-worked Type 316 stainless steel irradiated in HFIR

Description: Immersion density and elevated-temperature tensile properties were determined on 20%-cold-worked type 316 stainless steel irradiated in the HFIR at approximately 285, 370, 470, 560, and 620/sup 0/C to fluences of 1.8 to 6.2 x 10/sup 26/ neutrons/m/sup 2/ (> 0.1 MeV), which resulted in displacement damage levels of 16 to 54 dpa and helium concentrations of 900 to 3300 at. ppM. Tensile tests were done at temperatures near the estimated irradiation temperatures. Swelling increased with increasing … more

Irradiation performance of pyrolytic silicon carbide coatings on fissile fuel particles

Description: Fuel particles for the High Temperature Gas-Cooled Reactor (HTGR) contain a layer of pyrolytic silicon carbide to act as a miniature pressure vessel and primary fission product barrier. Optimization of the SiC coating with respect to fuel performance involves four areas of study: (a) characterization of as-deposited SiC coatings; (b) thermodynamics and kinetics of chemical reactions between SiC and fission products; (c) irradiation behavior of SiC in the absence of fission products; and (d) the… more

Feasibility studies of a helium-jet-coupled isotope separator at LAMPF

Description: For the past three years, studies have been carried out to assess the feasibility at LAMPF of using a He-jet gas activity transport system coupled to an on-line mass separator. The factors favorable for such a system are presented, and the problem areas relative to use of the system on the 800-..mu..A main beam line are outlined. Experiments were designed to address these problem areas. Results of the studies are presented, along with some estimates of yields of nuclei far from stability using … more

Summary of workshop recommendations

Description: The recommendations by the various groups regarding instrumentation are summarized. Almost all the instruments have been recommended by more than one workshop group. This indicates that a multidisciplinary group should be involved in detailed planning and design for these instruments. To judge whether the preliminary plans for beam facilities are consistent with these workshop recommendations, it is assumed that three instruments can be installed on a guide and one instrument on a horizontal or… more

Measurements of the HEU and LEU in-core spectra at the Ford Nuclear Reactor

Description: The Ford Nuclear Reactor (FNR) at the University of Michigan has been serving as the test site for a low-enriched uranium (LEU) fuel whole-core demonstration. As part of the experimental program, the differential neutron spectrum has been measured in a high-enriched uranium (HEU) core and an LEU core. The HEU and LEU spectra were determined by unfolding the measured activities of foils that were irradiated in the reactor. When the HEU and LEU spectra are compared from 1 MeV to 10 MeV, significa… more

Design and operation of a rapid thermal transient component testing sodium loop

Description: A specific problem developed during the design of an on-line sampling system for the Sodium Loop Safety Facility fast breeder reactor experiments. Rapid fluctuations in the sodium temperature, caused by reactor operation and shutdown, exposed the system components to conditions that could result in fatigue failure. A component test loop was designed and built at the Idaho National Engineering Laboratory to allow experimental qualification of component integrity. This paper outlines test system … more

Reirradiation of HFIR specimens in FFTF. [PCA alloy]

Description: A series of AISI 316 and PCA specimens previously irradiated in HFIR to doses ranging from 10 to 44 dpa have been measured to determine their density and then included in the MOTA irradiation experiment for continued irradiation in FFTF. These specimens were divided into two subsets to be discharged after 30 and 60 dpa.

Fatigue behavior at 650/sup 0/C of 20%-cold-worked type 316 stainless steel irradiated at 550/sup 0/C in the HFIR

Description: Type 316 stainless steel in the 20%-cold-worked condition was irradiated in the High Flux Isotope Reactor (HFIR) and subsequently tested in fatigue. The specimens were irradiated at 550/sup 0/C to damage levels of 8 to 12 dpa and transmutation helium levels of 300 to 500 at. ppM. Fatigue testing at 650/sup 0/C revealed that cyclic life was not significantly affected by the irradiation. However, unlike the results of tests of the same material at 550/sup 0/C, no endurance limit was observed. The… more
