A fuel/coolant interaction (FCI) is a phenomenon that may occur during a light water reactor severe accident when molten fuel comes into contact with residual water in-vessel or in the reactor containment. A new one-dimensional multifluid transient model, which currently has the capability of examining nonexplosive FC…

—Linear low-density polyethylene (LLDPE) was reinforced with chemithermomechanical (CTMP) aspen fiber, wood flour, and cellulose flour. Wood fibers were treated with isocyanate or a vinylsilane coupling agent to improve the adhesion between the fiber and polymer. Composites were made at different weight percentages of…
Description Provides overviews of the major developments in fracture mechanics and associated applications over the past 20 years, and highlights directions for future developments and applications. 6 major sections include: • Analytical Fracture Mechanics • Nonlinear and Time Dependent Fracture Mechanics • Microstruc…
Description STP 1033 provides a unique perspective on stabilization and solidification research as performed by the hazardous and radioactive waste communities. These papers are grouped into 4 sections: Processes; Regulatory Aspects and Testing Methods; Laboratory Evaluation; and Large Scale Evaluation or Demonstratio…
F.t.i.r. spectroscopy has been used for the study of dehydration of heteropolyacids (HPA) of the series H3+xPMo12–xVxO40 carried out in vacuo at 298–673 K and also for the study of ammonia sorption on the same samples. Pumping at room temperature results in the departure of water of crystallization; the protons, which…
A sulfide ion at the center of an Ni6 prism capped by two additional Ni atoms, and the presence of nine μ2-StBu bridges are the characteristic features of the structure of 1. The mean oxidation state for nickel in diamagnetic 1 is + 1.25. The anion 1 is the first pure nickel–sulfur complex with nickel in an unusual ox…
Grain‐oriented Bi 4 Ti 3 O 12 ceramics have been prepared by hot‐pressing. Platelike grains align during hot‐pressing; the long‐axis direction perpendicular to the crystal c axis is oriented perpendicular to the pressing direction. The effects of hotpressing conditions such as temperature, pressure, time, and type of…
The heteropolyanions [XW11O39{MnII(OH2)}]n–[X = P(1), Si (2), Ge (3), or B (4)] and α2-[P2W17O61{MnII(OH2)}]8–(5) have been transferred into non-polar solvents (benzene, toluene) with the aid of tetraheptylammonium bromide or other phase-transfer agents. Following dehydration of their non-polar solutions, anions (2) a…
The band gap of the mixed perovskite BaSn1–xSbxO3 has been reported to be 134 kJ mol–1(J-M. Hermann, M. R. Nunes and F. M. A. da Costa, J. Chem. Soc., Faraday Trans. I, 1982, 78, 1983), corresponding to 1.4 eV, which is the optimum value for solar-energy conversion. In order to confirm this value, pressed discs of the…
The increased discharge burnups envisaged today require an optimization of the Zircaloy cladding properties with regard to corrosion with different strategies for optimizing the corrosion for boiling water reactor (BWR) and pressure water reactor (PWR) applications. A broad laboratory study showed that the influence o…
The monthly flux of diatom taxa at four sites in two fjords of British Columbia, Canada, was determined over a 3-year period by particle interceptor traps. Saanich Inlet is a small basin with little horizontal density gradient while Jervis Inlet experiences seasonal runoff and strong vertical stratification. The basic…
The coercivity of Nd-Fe-B sintered magnets has been improved by Al additions. To study the microstructural effect of Al addition, two types of investigation were formed: (1) the change in the wetting behavior of the liquid phase, at the sintering temperature, was studied by measurements of the wetting angle; and (2) t…
The hot working is done at a low strain rate (hot pressing) and a high strain rate (hot rolling). Magnetic alignment induced by the hot working is found to be closely related to the microstructure of the cast ingots and the direction of principal stress. The appropriate structure is a columnar structure. The c-axis of…
Amorphous BN that contains hydrogen could be synthesized by pressure pyrolysis of borazine below 700°C at 100 MPa. The fraction of B and N bonded to H in the pyrolysis product could be controlled by changing the pressure pyrolysis condition. The pyrolysis product at 700°C and 100 MPa showed formation of B‐N‐B bonds of…
From the variation of magnetic properties with temperature trans-bis[1,2-bis(diethylphosphino)ethane]-di-iodochromium(II) undergoes a sharp S= 2 to S= 1 spin-state transition between 165 and 175 K.
The rate of alkene epoxidation promoted by 30% H2O2 and catalysed by MnIII tetra (2,6-dichlorophenyl)porphyrin is strongly enhanced by the addition of lipophilic carboxylic acids and lipophilic imidazole or pyridine axial ligands, in 1–8 : 1 and 1 : 1 molar ratios with respect to the porphyrin.
—The influence of the roughness of solid surfaces on the contact angle hysteresis, Δ, was studied for low-energy solids (paraffin, PTFE, PMMA) using pure liquids. Taking Δ as dependent on the roughness, the contact angle data can be linearly approximated. The value of Δ = 0 is considered as the equilibrium contact ang…

Three kinds of corrosion tests, a humidity test (80 degrees C, 90% RH), an autoclave test (120 degrees C, 2 atm saturated with water vapor), and a salt spray test (35 degrees C, 5% NaCl), were performed on a sintered magnet treated with nickel plating. For comparison, samples with epoxy resin coating, Al ion plating,…
