Designation of facility usage categories for Hanford Site facilities

Description: This report summarizes the Hanford Site methodology used to ensure facility compliance with the natural phenomena design criteria set forth in the US Department of Energy Orders and guidance. The current Hanford Site methodology for Usage Category designation is based on an engineered feature's safety function and on the feature's assigned Safety Class. At the Hanford Site, Safety Class assignments are deterministic in nature and are based on teh consequences of failure, without regard to the l… more

Chemistry of Anhydrous Systems Containing Hydrogen Fluoride and Nitrogen Oxides

Description: Nitrosyl and fluoride ions are formed in liquid anhydrous hydrogen fluoride when nitric oxide, nitrogen sesquioxide, nitrogen tetroxide, or nitrosyl fluoride, are dissolved. Vapor infrared analysis was used to study the solution composition and gaseous reaction products. These solutions react with metallic uranium, plutonium, zirconium, iron, and aluminum, as well as ceramic uranium oxide and uranium carbide, forming soluble nitrosyl metal fluoride complexes and liberating nitric oxide. The ura… more

Mechanical properties of 0. 2 g/cm/sup 3/ polystyrene bead foam

Description: In order to better interpret the results from a strain gage investigation of the effects of stress induced by polystyrene bead foam (PSBF) on electronic devices, the tensile and compressive properties of 0.2 g/cm/sup 3/ potting PSBF needed to be determined. These data are also required for mathematical models being employed to predict the force PSBF may exert on components. The properties were determined to be a function of temperature and residual pentane (blowing agent) content at -54/sup 0/,… more

Fundamentals of interruption in vacuum. Eleventh progress report

Description: During the past three months effort has concentrated on formulating a method to predict the enhancement of electrode surface field and power input occasioned by the presence of a projection on the electrode surface, during the ion sheath development period which attends the scavenging a contact gap following current interruption in vacuum. In addition, experimental evidence has been obtained to support the theory, postulated earlier, of a turn-around interval for electrons left in the gap, whic… more

Meteorological evaluation of multiple reactor contamination probabilities for a Hanford Nuclear Energy Center

Description: The conceptual Hanford energy center is composed of nuclear power plants, hence the name Hanford Nuclear Energy Center (HNEC). Previous topical reports have covered a variety of subjects related to the HNEC including: electric power transmission, fuel cycle, and heat disposal. This report discusses the probability that a radiation release from a single reactor in the HNEC would contaminate other facilities in the center. The risks, in terms of reliability of generation, of this potential contam… more

Three-dimensional computer modeling of dynamic reconnection in the magnetotail

Description: Two- and three-dimensional computer models of the dynamics of the magnetosphere and in particular the magnetotail have shown, that the basic features of the idealized linear or steady state reconnection theory are still found in time dependent and spatially more complicated configurations such as the magnetotail, which basically resembles a plane sheet pinch but in addition has small magnetic field components perpendicular to the sheet, field line flaring and variations along both directions pa… more

Materials testing using laser energy deposition

Description: A convenient method for determining the elastic constants of materials has been devised using the energy from a Q-switched neodymium-glass laser. Stress waves are induced in materials having circular rod or rectangular bar geometries by the absorption of energy from the laser. The wave transit times through the material are recorded with a piezoelectric transducer. Both dilatation and shear wave velocities are determined in a single test using an ultrasonic technique and these velocities are us… more

Nuclear power plant fire protection: philosophy and analysis. [PWR; BWR]

Description: This report combines a fire severity analysis technique with a fault tree methodology for assessing the importance to nuclear power plant safety of certain combinations of components and systems. Characteristics unique to fire, such as propagation induced by the failure of barriers, have been incorporated into the methodology. By applying the resulting fire analysis technique to actual conditions found in a representative nuclear power plant, it is found that some safety and nonsafety areas are… more

Experiments on cold-trap regeneration by NaH decomposition. [LMFBR]

Description: Cold-trap regeneration may be very important in future LMFBRs because of the expected high hydrogen source from the steam generators. This hydrogen precipitates as NaH in the cold trap and may fill the trap within one year of operation. Several methods of cold-trap regeneration were considered, but the simplest and least expensive appears to be decomposition of NaH under vacuum at elevated temperatures. Experiments were done to assess the feasibility of this method for cold-trap regeneration. S… more

Resource book: Decommissioning of contaminated facilities at Hanford

Description: In 1942 Hanford was commissioned as a site for the production of weapons-grade plutonium. The years since have seen the construction and operation of several generations of plutonium-producing reactors, plants for the chemical processing of irradiated fuel elements, plutonium and uranium processing and fabrication plants, and other facilities. There has also been a diversification of the Hanford site with the building of new laboratories, a fission product encapsulation plant, improved high-lev… more

Finite element welding computations using general purpose nonlinear analysis codes

Description: Parts being welded experience high local temperatures and severe thermal gradients which lead to large local stresses due to nonuniform thermal expansion and contraction. Unacceptable degradation of material mechanical properties, residual stresses, and changes in geometry can result. General purpose nonlinear finite element method analysis codes offer features which should facilitate their use for predicting welding temperatures, displacements, and stresses. A series of computations evaluating… more

DEVELOPMENT OF PLUTONIUM BEARING FUEL MATERIALS. Progress Report for period July 1 through September 30, 1961

Description: Data are tabulated for the characteristic parameters of PuO/sub 2/ powders prepared by the continuous oxalate precipitation process. The results show that the PuO/sub 2/ surface area decreases almost linearly with calcination hold times at 760 deg C. A thermogravimetric study of the decomposition of Pu oxalate indicate the formation of an initial stable compound at ~ l00 deg C and a stable intermediate at ~ 300 deg C. Characteristic data are tabulated for UO/sub 2/ -5% PuO/sub 2/ and UO/sub 2/-… more
