Pressure Rise in HRT Shield Due to Reactor and Replacement heat Exchanger Rupture

Description: .Recalculations were made of HRT cell pressures in the event of a simultaneous rupture of the reactor core vessel and the fuel and blanket heat exchangers. These calculations will be applicable after the replacement fuel heat exchanger is installed. The pressure rise in the cell is plotted as a function of time. A maximum cell pressure of 34 psig is achieved ~7 sec after rupture.

The Effect of Thermal Cycling on the Thermal Transfer from a Sand Blasted Slug to an Unbonded Jacket

Description: Abstract. Measurements were made to determine the effect of thermal cycling on heat transfer from slug to jack using a slug with a sand blasted surface. The value of the transfer coefficient h decreased from initial values ranging from 10 to [formula], to values and [formula] after 1700 cycles, and to a range of 0.15 to 0.45 [formula] after 3200 cycles. Comparisons are made with the results found for slugs with different surfaces.

The Thermal Conductivity of Uranium Monocarbide

Description: Uranium carbide shows promise as a fuel material for reactors operating at relatively high temperatures based on its high melting point, high uranium density and high thermal conductivity. Before refined reactor designs can be made, however, good quantitative data on the thermal conductivity at temperatures in excess of 1000C is required. This technical report presents data gathered as part of a continuing study aimed at determining the thermal conductivity of refractory uranium fuels as a func… more

Floating substrate process. First quarterly progress report, January 6, 1976--March 28, 1976

Description: Laboratory apparatus has been designed, built, and put into operation to study the supercooling of Sn--Si melts and the uptake of silicon from silanes. Values of supercooling of Sn--Si melts as high as 78/sup 0/C at 1100/sup 0/C and 39/sup 0/C at 1200/sup 0/C have been observed. Results to date have been limited by nucleation caused by foreign material floating on the surface of the melt. Spontaneously nucleated planar platelet growth has been observed at the Sn--Si supercooled surface having g… more

User's guide to the LLL basic interpretere

Description: Scientists are finding increased applications for microprocessors as process controllers in their experiments. However, while microprocessors are small and inexpensive, they are difficult to program in machine or assembly language. A high-level language is needed to enable scientists to develop their own microprocessor programs for their experiments on location. Recognizing this need, LLL contracted to have such a language developed. This report describes the result -- the LLL BASIC interpreter… more

Transient analysis Brayton Isotope Power System supplement I

Description: The purpose of this study was to obtain a simulation of the most rapid start-up thermal transient which would be encountered in the BIPS operation. As an aid in reducing the severity of the transient, it was agreed with the NASA that the case to examine would be determined by the following logic: (a) determine the lowest temperature at which a start could be accomplished using a 2 HSA configuration; and (b) define the transients for a 3 HSA start which was initiated when the heat source achieve… more

Temperature-profile determination using frequency-domain reflectometry

Description: The temperature distribution along a coaxial electrical cable can be determined by means of frequency-domain reflectometry if the cable has an inner sheath of a suitable temperature-sensitive dielectric material. Such a technique would have advantages in cost and convenience over the conventional method of placing a separate thermocouple at each point where the temperature is to be measured. It would be especially useful for underground applications in assessing geothermal reservoirs and in ins… more

Nuclear safeguards progress report, July--December 1975

Description: The gamma-ray energy region from 120 to 350 keV was investigated using a 1-cc planar Ge(Li) detector. Plutonium isotopic ratios are presented for 0.25 g NBS Standard Reference Material. The results show the feasibility of obtaining /sup 240/Pu and /sup 241/Am isotopic ratios to better than 5 percent of the chemical value by using gamma-ray spectrometers having 600-eV resolution at 122 keV. A single exponential equation has been used to predict the equilibrium of a 1-in. x 3-in. calorimeter (Mou… more

Extraction, separation and analysis of high sulfur coal

Description: In summary, significant bond cleavage was found only for thiophenol under the supercritical conditions studied. Less than 5% yield was found for the observed reaction products for all the other organosulfur compounds. The hydrogen sulfur bond in thiophenol is clearly the weakest of those studied and therefore it is the easiest to rupture. Also a general trend was observed the solvolysis reaction products such as ethylthiobenzene were the products initially formed at lower temperatures. But with… more

Post-Closure Groundwater Monitoring Plan for the 1324-N Surface Impoundment and 1324-NA Percolation Pond

Description: The 1324-N Surface Impoundment and the 1324-NA Percolation Pond, located in the 100-N Area of the Hanford Site, are regulated under the Resource Consevation and Recovery Act (RCRA). Surface and underground features of the facilities have been removed and laboratory analyses showed that soil met the closure performance standards. These sites have been backfilled and revegetated.

Experimental Results in Support of Simulating Progressive Crush in Carbon-Fiber Textile Composites

Description: This report summarizes the findings of an experimental program conducted to support the modeling of the crush behavior of triaxial braid carbon fiber composites. The matrix material as well as braided panels and tubes were characterized in order to determine material properties, to assess failure modes, and to provide a test bed for new analytical and numerical tools developed specifically for braided composites. The matrix material selected by the ACC was an epoxy vinyl ester (Ashland Hetron 9… more

A Measurement Technique to Determine the Sensitivity of Trained Dogs to Explosive Vapor Concentration

Description: Over the years canines have been used successfully to detect explosives. However, exactly what a canine detects in the many thousands of explosive formulations available is still not well understood. LLNL and Bureau of Alcohol, Tobacco and Firearms (BATF) studies over the past four years are beginning to provide better insight into this complex problem. One area that has been addressed is how low a molecular concentration of nitromethane explosive can a canine detect. Forty-one canine/handler t… more

Year 6 Post-Remediation Biomonitoring and Phase II Source Investigation at the United Heckathorn Superfund Site, Richmond, California

Description: The Heckathorn Superfund Site in Richmond, California, encompasses the property of the former United Heckathorn pesticide packaging plant and the adjacent waterway, Lauritzen Channel. The site was used from 1945 to 1966 by several operators to produce various agricultural chemicals. The site was placed on the National Priorities List of Superfund sites in 1990, which resulted in the removal of pesticide-contaminated soil from the upland portion of the site and dredging the marine portion of the… more

Thermal analysis of the horizontal shipping container for normal conditions of transport with solar insolation

Description: A thermal analysis of the horizontal shipping container (HSC) was performed to determine the temperatures at the outer surface of the inner container during normal conditions of transport with incident solar radiation. There are two methods by which this analysis can be performed: (1) it can be run as a steady-state problem where it is assumed that the incident solar radiation is applied to the package 24 hours per day, or (2) it can be run as a cyclic transient problem where the incident solar… more
