In his relatively short life of 57 years, Ernest Orlando Lawrence accomplished more than one might believe possible in a life twice as long. The important ingredients of his success were native ingenuity and basic good judgement in science, great stamina, an enthusiastic and outgoing personality, and a sense of integrity that was overwhelming. Many articles on the life and accomplishments of Ernest Lawrence have been published, and George Herbert Childs has written a book-length biography. This biographical memoir, however, has not made use of any sources other than the author's memory of Ernest Lawrence and of things learned from him. A more balanced picture will emerge when Herbert Childs biography is published; this sketch simply shows how Ernest Lawrence looked to one of his many friends.

Declassified 21 Sep 1973. This report covers six programs: (1) studies of substoichiometric urania and urania solid solutions above 1700 deg C and their compatibility with refractory metals; (2) refractory-metal fuel element development for operation in non-oxidizing atmospheres; (3) specific materials properly data for various refractory metals and alloys and refractory-metal--UO/ sub 2/ composites; (4) fission product transport processes in refractory-metal fuel systems at temperatures exceeding 1400 deg C; (5) development of long-life, fueled and unfueled, clad metal hydrides, control elements, and shield materials; and (6) the effect of high fuel burnup on BeOstabilized fuel materials.

The minimum travel time of 79 days observed for /sup 3/H at the point of maximum flow along the riverbank spring-front gives a minimum decay time that can be also applied to other radioisotopes discharged to the crib. Actual travel times of isotopes discharged to the site are dependent on the interaction of the isotopes with the sediments (ion-exchange, chemical, adsorption, etc.). A travel time of 101 days observed for /sup 131/I is an indication of the dependence of actual migration rates on the isotope's interaction with the soil materials. The interaction of most isotopes with sediments is significantly greater than that of iodine. Therefore, most isotopes will have much ionger travel times. Significant quantities of the waste appear to be flowing northeast from the site into the Columbia River below 100-D Area. This would increase the length of flow path and travel times to the river by a factor of 10. Estimates of the distribution of long-lived isotopes at the site are based on laboratory measurements. Field evaluations of the actual distributions of long-lived isotopes are in progress. This study involves drilling and sampling of the sediments in and near the crib. Analyses of radiocontaminants in these samples will …

Approximately 13 kg of U-233 were fabricated into 1 wt % UO/sub 2/-ThO/sub 2/ and 26 wt % UO/sub 2/-ZrO/sub 2/ pellets and enclosed in Zircaloy-2 cladding tubes as 1299 blanket and 377 seed rods. The U-233 contained 38 ppM of U-232, and was purified as two batches of liquid UO/sub 2/(NO/sub 3/)/sub 2/ immediately prior to processing into powder form. All fuel rods were completed within 95 days of this initial solvent extraction of the nitrate. Overall U yield of nitrate to usable materials was over 90%, and only 14 rods were rejected in welding and all without loss of contained fuel. (NSA 21: 14872)
