Abstracts of the first ORNL workshop on polycyclic aromatic hydrocarbons: characterization and measurement with a view toward personnel protection. [PAH from coal conversion]

Description: This report contains the abstracts of papers presented at a workshop on polycyclic aromatic hydrocarbons (PAH) such as those produced by coal conversion technologies. Their often carcinogenic nature imposes the obligation of providing adequate protection and measurement devices for workers and for the general public. The primary questions are as follows: What should be measured. Where and how should it be measured. What are the maximum permissible concentrations. This workshop and future worksh… more

Acoustic cavitation as a mechanism of fragmentation of hot molten droplets in in cool liquids. [LMFBR]

Description: A mechanism that explains several of the observations of fragmentation of hot molten drops in coolants is presented. The mechanism relates the fragmentation to the development of acoustic cavitation and subsequent bubble growth within the molten material. The cavitation is assumed due to the severe pressure excursions calculated within the hot material as a result of the pressure pulses accompanying coolant vaporization at the sphere surface. The growth of the cavitation vapor nuclei inside the… more

Adhesive bonding of TATB/Kel-F 800

Description: Triaminotrinitrobenzene (TATB) bonded with a copolymer of chlorotrifluoroethylene and vinylidene fluoride (Kel-F 800) was selected as the high explosive for use in the B77 bomb. The plastic-bonded explosive (RX-03-BB, 7.5 percent Kel-F 800) has high strength and is less sensitive to shock initiation than most previously used high explosives. Adhesive bonding of RX-03-BB has proved to be difficult, however, because of the chemical composition of both the TATB and the binder. Studies of the criti… more

Analysis of a neutron scattering integral experiment on iron for neutron energies from 1 to 15 MeV

Description: Monte Carlo calculations were made to analyze the results of an integral experiment with an iron sample to determine the adequacy of neutron scattering cross section data for iron. The experimental results analyzed included energy-dependent NE-213 detector count rates at a scattering angle of 90 deg and pulse-height spectra for scattered neutrons produced in an iron ring pulsed with a 1- to 20-MeV neutron source. The pulse-height data were unfolded to generate secondary neutron spectra at 90 de… more

Analysis of transients in the SRP test pile

Description: Analysis of the hypothetical upper limit accident in the Savannah River Test Pile showed that the offsite thyroid dose from fission product release would be <2.2 x 10/sup -3/ of the 10-CFR-100 guideline dose for 95 percent of measured meteorological conditions. Offsite whole body dose would be negligible. The Test Pile was modified to limit the length of test piece that can be charged to the pile. These modifications reduce the potential offsite dose to <2.2 x 10/sup -5/ of the regulatory guide… more

Annual technical progress report inducer pump program government fiscal year 1976 and 1976T. [LMFBR]

Description: The Inducer Pump Program was initiated to demonstrate the applicability and advantages of an inducer pump to the LMFBR. The inducer is a pump blading which is specifically tailored to provide excellent suction performance. Operating suction specific speeds two to three times those for the inlet of a centrifugal impeller can be achieved with a properly and conservatively designed inducer. When coupled to a centrifugal impeller, the inducer offers excellent suction performance which can be effect… more

Anomalous spatial depletion of the lower hybrid cone through parametric decay

Description: Analytic solution for the envelope structures of two nonlinearly coupled lower hybrid waves propagating along their respective cone trajectories are obtained. The coupling occurs through induced scattering by particles. The results indicate anomalous spatial pump depletion may be important for present and future large scale tokamaks. Implications to plasma heating are also discussed.

Assessment of very high-temperature reactors in process applications

Description: An overview is presented of the technical and economic feasibility for the development of a very high-temperature reactor (VHTR) and associated processes. A critical evaluation of VHTR technology for process temperatures of 1400 and 2000/sup 0/F is made. Additionally, an assessment of potential market impact is made to determine the commercial viability of the reactor system. It is concluded that VHTR process heat in the range of 1400 to 1500/sup 0/F is attainable with near-term technology. How… more

Banana drift diffusion in a tokamak magnetic field with ripples

Description: The drift motions of trapped particles in a tokamak field with ripples lead to a new transport process in large tokamaks in addition to the diffusion process due to particles trapped in the ripples. We study this problem by solving the bounce averaged drift kinetic equation with a model collision operator. It is shown that the ''banana drift diffusion'' is proportional to the collision frequency when the poloidal banana drift frequency is smaller than the effective collision frequency. This res… more

Benchmark Testing of the Finite-Strain Version of the LIFE-III Fast-Reactor-Element Code

Description: A collection of benchmark problems is used to test the finite-strain formulation of the LIFE-III fast-reactor fuel-element code. Analytical solutions for thick-wall cylinders loaded by internal and external pressure, valid for arbitrarily large strains, are presented for a linear viscous material. Similar problems are formulated for a nonlinear material, and numerical solutions are obtained using the Runge-Kutta method for the integration of an ordinary differential equation. These solutions ar… more
