Wear and corrosion performance of metallurgical coatings in sodium

Description: The friction, wear, and corrosion performance of several metallurgical coatings in 200 to 650/sup 0/C sodium are reviewed. Emphasis is placed on those coatings which have successfully passed the qualification tests necessary for acceptance in breeder reactor environments. Tests include friction, wear, corrosion, thermal cycling, self-welding, and irradiation exposure under as-prototypic-as-possible service conditions. Materials tested were coatings of various refractory metal carbides in metall… more

Overview of Modeling and Simulations of Plutonium Aging

Description: Computer-aided materials research is now an integral part of science and technology. It becomes particularly valuable when comprehensive experimental investigations and materials testing are too costly, hazardous, or of excessive duration; then, theoretical and computational studies can supplement and enhance the information gained from limited experimental data. Such is the case for improving our fundamental understanding of the properties of aging plutonium in the nuclear weapons stockpile. T… more

A structural evaluation of the Shippingport reactor pressure vessel for transport impact conditions

Description: The Shippingport Atomic Power Station in Shippingport, Pennsylvania, is being decommissioned and dismantled. This government-leased property will be returned, in a radiologically safe condition, to its owner. All radioactive material is being removed from the Shippingport Station and transported for burial to the DOE Hanford Reservation in Richland, Washington. The reactor pressure vessel (RPV) will be transported by barge to Hanford. This paper describes an evaluation of the structural respons… more

Electron microprobe analysis of irradiated S8ER cladding

Description: Extensive precipitation was observed in S8ER cladding following irradiation. Electron microprobe analysis was proposed as a means to identify these precipitates. Subsequently, the electron microprobe was successfully used for qualitative analysis of unirradiated and irradiated S8ER cladding. The unirradiated, thermally aged control specimen analyzed showed two major precipitates. One, a randomly distributed intergranular phase, contained Ti, Mo, Fe, Cr and Ni and a second, a randomly distribute… more

Diagnostics in the Hostile Environments of a Prototype Fusion Reactor

Description: The first lecture begins by reviewing the various facets of a thermonuclear-type plasma that will likely require special considerations or hardening of the applied diagnostic instrumentation. Several factors are necessary to adopt relatively standard plasma diagnostic techniques to function satisfactorily in the more hostile environment of a thermonuclear-type plasma. This lecture contains a listing of the various types of expected hardening requirements for a representative set of diagnostic i… more

Fusion-neutron effects on magnetoresistivity of copper stabilizer materials

Description: The objective of this work is to quantify the changes which occur in the magnetoresistivity of coppers (having various purities and pretreatments, and at magnetic fields up to 12 T during the course of sequential fusion neutron irradiations at about 4/sup 0/K and anneals to room temperature. In conjunction with work in progress by Coltman and Klabunde of ORNL, the results should lead to engineering design data for the stabilizers of superconducting magnets in fusion reactors. These magnets are … more

Pile graphite expansion

Description: The purpose of this memorandum is to present and analyze, in terms of the current status of knowledge of radiation damage to graphite, the data available at the present time on the expansion status of the graphite in the piles, and suggest, in terms of this analysis, several possibly feasible curative and preventive measures. The portion of the data to be covered in this memorandum consists of that obtained during the last four years from pile motion measurements and from tube bowing measuremen… more

E Division activities report, FY 1976

Description: Some of the activities in E (Experimental Physics) Division are described. E Division carries out basic and applied research in atomic and nuclear physics as well as in material and biomedical sciences, centered around the Laboratory's four major accelerators. Experiments are grouped under the headings of neutron, photon, and charged-particle interactions. Investigations in this past year involved fission cross sections, nuclear reactions with neutrons, charged particles and gamma rays, in… more

OZONE EXPLOSION IN IRRADIATED CRYOGENIC APPARATUS AND IMPLICATIONS UPON N.S. SAVANNAH GASEOUS WASTE DISPOSAL SYSTEM

Description: The several incidents of ozone explosions in cryogenic apparatus in radiation fields are reviewed. It is concluded that the explosions may be avoided if oxygen regions where, in static systems they tend to concentrate by liquefaction. Such provisions would make the proposed circulating N/sub 2/- cooled trap for the N.S. Savannah off-gas system acceptable if the initial oxygen content of the nitrogen coolant is less than 200 ppm. Higher concentrations are undoubtedly safe but the lack of informa… more

NIF diagnostic damage and design issues

Description: The NIF target environment is evaluated with respect to target and diagnostic debris and with respect to instrument survivability in the presence of target debris and radiation. Quantitative estimates are arrived at by extrapolating from Nova and Omega experience using simple scaling arguments. Specifically, we evaluate the closest distance of approach of various components of DIM-based diagnostics such as target mounted pinhole arrays, open detectors, filters, x-ray optics, and spectrometers. … more

The Stability of Purex Solvent to Radiation and Chemical Attack

Description: The effects of variables on the rate of Purex solvent deterioration were investigated with the emphasis on those deterioration products which cannot be removed by carbonate washing. The deterioration rate was found to be directly proportional to the acid and nitrate ion concentrations, and proportional to the square root of the concentration of nitrite ion. Other observations on the effects of temperature, relative merits of brand name solvents, and the effects of radiation are included. A meth… more

Diagnostics in the Hostile Environments of a Prototype Fusion Reactor

Description: Various facets of a thermonuclear type plasma that will likely require special considerations or hardening of applied diagnostic instrumentation are reviewed. The discussion will include both on-line diagnostic instrumentation requirements for satisfactory operation and considerations to reduce integrated radiation damage sufficiently for a reasonable diagnostic lifetime.

Defect Production Efficiencies in Thermal Neutron Irradiated Copper and Molybdenum

Description: We have derived the primary recoil spectra for thermal neutron capture in copper and molybdenum, and have calculated the damage energy cross-sections needed to determine the defect production efficiencies from measured resistivity damage rates. These efficiencies, which are in excellent agreement with fully dynamic computer simulations of collision cascades, are compared to the predictions of displacement functions which are currently in use.
