Evaluation of macroreticular anion exchange resin - RTA-893-R

Description: The macroreticular anion exchange resin, Amberlite IRA-900-OH, and an experimental resin from Ionac Chemical Company were irradiated by a /sup 60/Co source to doses of 5 x 10/sup 7/ rad and 10/sup 8/ rad. These doses approximate or exceed the dose encountered by the deionizer resins in 100-Area service. The loss in exchange capacity and the volume changes of Amberlite IRA-900 on irradiation were similar to those found previously for Amberlite IRA-400. The Ionac experimental resin, which had a c… more

CHEMICAL EVOLUTION

Description: How did life come to be on the surface of the earth? Darwin himself recognized that his basic idea of evolution by variation and natural selection must be a continuous process extending backward in time through that period in which the first living things arose and into the period of 'Chemical Evolution' which preceded it. We are approaching the examination of these events by two routes. One is to seek for evidence in the ancient rocks of the earth which were laid down prior to that time in whi… more

Thermo-physics technical note No. 43: SNAP fuel particle dispersion

Description: An evaluation of particle dispersion from natural and artificial sources has been made relating this information to circulation processes in the mesosphere, stratosphere, and troposphere. The data on natural particle and nuclear debris dispersion have been interpreted in terms of their significance in regard to SNAP fuel reentry dispersion and extended by various fall-out time and dispersion calculations.

Letter to N.T. Saunders NASA-Lewis Research Center

Description: Studies during the last two years have shown that the pneumatic impaction process is a flexible process for the production of cermet fuel elements. However, there is still much basic information to be acquired about the process before the limits of process capability can be established. Development work proposed herein is intended to continue optimization of the process, to establish the process parameters necessary to a pilot plant or production line operation, and to better define the process… more

Supplement B to Production Test IP-669-AC depleted uranium irradiation smaller reactors

Description: The objective of this supplement is to authorize an increase in the maximum goal exposure of the depleted uranium columns to 2400 MWD/T. The parent documents, while intending to produce 25 Kg of 18 w/o Pu-240, made it clear that these would be minimum requirements and ``every reasonable effort will be made to exceed both {hor_ellipsis} 25 Kg and 18 w/o Pu-240.`` Operation to date shows excellent performance of the target element, and an increase in the depleted uranium goal exposures would both… more

DATA SET FOR LOW-SPEED REMOTE TERMINALS

Description: Data transmission over telephone lines involves the acceptance of serialized binary data, modulation of the data to a signal suitable to the bandwidth of the telephone. channel, transmission of the signal over the line, reception at the receiving end and demodulation of the signal to reproduce the original binary data. One typical application of data communication is between a low-speed terminal and a computer. In such a case, full-duplex operation is often desirable (i,e., transmission of info… more
