A new constant monitor for ruthenium and iodine in stack gases. Status report (open access)

A new constant monitor for ruthenium and iodine in stack gases. Status report

Present methods for monitoring Ru{sup 103}, Ru{sup 106}, and I{sup 131} in stack gases involve sampling by filtration and scrubbing and analysis by chemical separation and counting or by gamma spectrometry. Filtered samples, which are ordinarily collected over a complete day, are analyzed for total ruthenium and iodine by gamma spectrometry and for the individual isotopes by chemical separation and counting. The present scrubber monitors the sampler gas for total activity. As an aid to Radiological Sciences evaluation of stack gas hazards and to operations control of radioactive gas emission, Methods and Instrument Development collaborated on the planning of a continuous monitoring system. This memorandum has the purpose of outlining the plan, reviewing progress since conception in October, 1953, and reporting work still to be done.

Production Test No. 105-519-SI irradiation service request No. HAPO 108: Studies of uranium crystal structure damage using low irradiation temperatures (open access)

Production Test No. 105-519-SI irradiation service request No. HAPO 108: Studies of uranium crystal structure damage using low irradiation temperatures

This document discusses studies of the behavior of uranium metal as a fuel element which previously have been hampered by the lack of understanding of the nature of radiation damage to the crystal structures. With the aid of the double crystal x-ray spectrometer, samples from irradiated fuel elements which had receive total exposure of 150 MWD/T and 1,000 MWD/T were studied and gross radiation damage was not present. Although these findings are of a preliminary nature, they are well in agreement with theoretical calculations in which the equilibrium concentration of displaced atoms at temperatures above 200{degrees}C would be extremely low. Assuming this to be the case, most of the crystallographic imperfection induced by pile radiations must have been annealed out of the metal studied. On the basis of this work it would seem quite likely that some fundamental facts about the nature of radiation damage could be learned by keeping the temperature low. This production test is designed so as to give information regarding the crystal structure damage where the uranium temperature during irradiation and post-irradiation operations is kept below 35{degrees}C.

Evaluation of nickel ferrocyanide scavenging of Uranium Recovery Plant solvent extraction waste (open access)

Evaluation of nickel ferrocyanide scavenging of Uranium Recovery Plant solvent extraction waste

The Uranium Recovery Plant, over the life of the operation, will be required to attain maximum recovery of stored uranium and to produce aqueous waste in a volume equivalent to the volume of stored uranium waste which, after acidification, constitutes the feed stream for the process. Due to variations in the composition of the feed stream, the waste stream does not consistently have a volume equivalent to the volume of the stored metal waste. This variation volume equivalence impedes tank farm scheduling because of the necessity for return of the process waste to underground tanks made available by the recovery operations. A plant test, using nickel ferricyanide to remove Cs-137 and Sr-90 from the Uranium Recovery Plant wastes has been completed and this memorandum has been prepared to summarize and report the results obtained from this test.

Production Test 105-524-A: Washer seal and seal leakage tests for the horizontal rod. Final report (open access)

Production Test 105-524-A: Washer seal and seal leakage tests for the horizontal rod. Final report

Production Test 105-524-A authorized the installation of a washer seal on the ``A`` horizontal control rod at C Pile in order to determine the characteristics of this type seal when used on unlubricated rods. The most important characteristic to be observed during the test was the gas leakage rate. A qualitative study of the seal wear and radiation damage to the seal were also to be made. This document reports the conclusion of the test and discusses the results obtained.

[Discussion by R. M. Evans at a meeting held with the members of the Military Liaison Committee on February 17, 1954]

Characteristics of the heavy water moderated and cooled reactor when fueled with natural uranium were compared with those of Hanford. The following topics were covered: (1) fundamental safety of the Savannah River Plant reactor and its fundamental efficiency as neutron collector; (2) many critical volumes result in a complex control system and high sensitivity of flux pattern to rod position changes; (3) due to lack of time had to sue slugs initially; (4) had to use D{sub 2}O sparingly; (5) effects of circulating cooling system; and (6) heat transfer considerations. Topics also discussed were Savannah River reactor with enriched loadings and irradiation of thorium in lieu of lithium alloy.
