The synthesis of many chemical compounds produces potentially dangerous exothermic reactions. The FORTRAN IV program described herein employs analytical techniques for the calculation of the batch temperature in a chemical reactor as a function of time. The program includes provisions for calculating (a) total batch and mass volume, (b) coolant and batch average thermodynamic properties, (c) heat transfer coefficients for the batch, wall, coolant, and the overall {open_quotes}U{close_quotes} value, and (d) reaction rates for zero through 3rd order reactions. The program is to be used for determining operating criteria (coolant flow rate, reactant feed rate, agitator speed, etc.) for maintaining batch temperatures at a safe level for processes with high exothermic heats of reaction or mixing.

The purpose of the standard is to establish the requirements for the design, fabrication, assembly and quality assurance for the procurement of the electro-mechanical devices intended to move and position control elements within the core of a liquid sodium cooled nuclear reactor. Only those drive mechanisms based upon a collapsible-rotor, roller-nut mechanical motor, energized by a magnetic field generated by an electrical coil, are governed by this Standard. These control rod drive mechanisms (CRDMs) may be connected to control rods having specific functions such as power regulation, power shimming, or safety shutdown, or any sequence or combination of these functions.

It is shown that rifampicin, and especially its relative dimethyl-N-benzyl-N-desmethyl rifampicin, can inhibit focus formation by Moloney sarcoma virus on BALB/3T3 tissue cultures. At a dose level of 10 {micro}g/ml DMB appears to totally inhibit focus formation while reducing virus replication by at least a factor of fifty and cell proliferation by only a factor of three. These observations, taken together with those of others, suggest a role for the hybrid RNA-DNA dependent DNA polymerase and the gene for its synthesis both in normal cell processes and in the transformation process.

Porous carbon and ceramic tubes were evaluated as supports for dynamically formed zirconium (IV) hydrous oxide-polycarboxylic acid hyperfiltration membranes. The most promising membranes were formed on Union Carbide 6-C carbon tubes using a 150,000 molecular weight polyacrylic acid. Sodium chloride rejections as high as 97% were obtained at water fluxes of 80 gpd/ft{sup 2} compared with rejections of 90 to 95% and fluxes of 130 gpd/ft{sup 2} using the porous stainless steel-Acropor/Millipore supports. The effects of pressure, circulation velocity, and temperature on membrane flux and sodium chloride and Coalinga water rejections were studied. A small industrial module containing 6-C carbon supports with a 3.04 ft{sup 2} filtration surface gave a salt rejection of 86% and a product water flux of 60 gpd/ft{sup 2}.

This document is intended to serve both as an historical record and final status report concerning the K Reactor hydriding problem which has been under study since its discovery in 1965. If neither of the K reactors are restarted, this will serve as an historical record which might be of some use to those using Zircaloy components in either the power reactor or chemical industries. (Its classification would limit such use.) If either of the K`s are reactivated, hydriding will again become an active subject since its deleterious effects on the tubes will have a significant bearing on future reactor operations. No attempt will be made to review or report on all work done on this problem but a complete list of references is appended. It is assumed that copies, or microfilms, of these references will be available for some time to come.

This collection of mathematical data consists of two tables of decimal constants arranged according to size rather than function, a third table of integers from 1 to 1000, giving some of their properties, and a fourth table listing some infinite series arranged according to increasing size of the coefficients of the terms. The decimal values of Tables I and II are given to 20 D.

This document summarizes by stack number the amount of radioactivity discharged from the facilities of Chemical Processing Division, Atlantic Richfield Hanford Company. Emission data for 231-Z Building and 2724-W, Laundry Building, which are operated by other AEC Contractors are not available for this report. Total beta, alpha and I{sup l3l} radioactive emissions from the stacks for 1970 were as follows: alpha (Pu, assumed) 1.59 {times} 10{sup {minus}1} C, alpha (U, assumed) 1.44 {times} 10{sup {minus}3} C, beta 1.93C, and I{sup 131} 4.92 {times} 10{sup {minus}1} C. Air samples taken continuously from gaseous release facilities were analyzed for total beta and alpha activity (and iodine activity, where applicable). Where sample data were not available, the total radioactive emission was adjusted by using the average emission rate prior to the subject period; or where activity was near constant, by using the daily average as a base. A gamma scan of the 291-S stack is included in the report.

On December 18, 1970, at 7:30 a.m., PST, a venting occurred at the Nevada Test Site in conjunction with the Baneberry test. The Lawrence Radiation Laboratory (LRL) Bio-Medical Research Division and the University of Utah responded to this event by activating their jointly operated air-sampling network and by gathering forage, milk, and animal samples. These data are used to calculate the dose to humans from inhalation, submersion, and food-chain contamination; food-chain contamination calculations are limited to the cow-milk pathway, but included bovine inhalation. The question of food-chain contamination is explored under both the actual situation that dairy cows were fed stored feed and under the hypothetical situation that dairy cows were fed fresh feed. Our results show that {sup 131}I was the significant radionuclide emitted by the event and that the strongest dose was received by the thyroid glands of both foraging animals and humans. The integrated concentrations of {sup 131}I were higher in the northern part of Utah; the maximum value of 1100 pCi h m{sup {minus}3} was recorded at Draper (near Salt Lake City). For conservative results, we calculated the dose to a child rather than an adult. For the actual conditions following the venting, we estimate on …

The purpose of this note is to show that the combination of implicit radiation transport and hydrodynamics, Compton scattering, and any other energy transport or exchange mechanism can be simply carried out by a splitting procedure. This means that the contributions to material energy exchange can be reckoned separately for hydrodynamics, radiation transport without scattering, Compton scattering, plus any other possible energy exchange mechanism. The radiation transport phase of the calculation would of course be implicit and would be carried out in exactly the manner described in UCRL-7294 but the hydrodynamics and Compton portions would not, leading to possible time step controls. In any case, the time step restrictions which occur on radiation transfer due to large Planck mean absorption cross-sections would not occur.
