Mechanism and kinetics of mineral absorption by plants. Annual progress report, October 1, 1965-September 30, 1966

Description: Plant nutrition was studied as a relation between aerobic respiration and ion uptake in barley. Potassium, chlorine, lithium, sodium, calcium, sulfates, and bicarbonates were studied by root absorption in varying concentrations of carbon dioxide atmospheres. (PSB)

K Reactor uncooled HCR: Equilibrium temperature study

Description: Temperature calculations were made on a proposed design of an uncooled horizonal control rod (HCR) for the K Reactors. The calculations were performed with the aid of a FORTRAN coded heat transfer program for the UNIVAC 1107. The results of the calculations indicate that such a control rod is feasible for.4400 Mw and 5000 Mw operation provided certain precautions are taken. These precautions include assuring good contact between the rod and the graphite in the high flux regions and Providing re… more

Minutes of meetings to discuss extraction test studies of ceramic coproduct targets

Description: The meetings were held on December 6 and 7, 1965 in the 325 Building conference room at PNL. The objectives of the meetings were: (1) To review the status of the ceramic coproduct target element fabrication technology and the subsequent extraction processing technology of irradiated elements as developed at PNL. (2) To discuss the feasibility of performing extraction studies of irradiated coproduct target elements at the SRL pilot plant facilities in demonstrating the capability of coproduct pr… more

Technical requirements and criteria for the coproduct target element

Description: The technical basis and criteria for five requirements are presented. Requirement 1 is that the coproduct target element shall be compatible with the driver element in the environment of the N-Reactor primary loop. Requirement 2 is that the target element shall be compatible with nuclear safety requirements under all credible accident conditions. Requirement 3 is that the coproduct element shall be unmistakable from other fuel element models in use or expected to be in use during the period 196… more

Theoretical density of lithium aluminate updated

Description: The ''handbook'' density for LiAlO/sub 2/ is 2.55 g/cc. Recent data show that it should be revised to 2.62 g/cc. In the future densities reported as percent of theoretical should be based on 2.62 g/cc as being 100 percent. Values quoted on this basis will be more realistic. In order to avoid confusion it will be necessary to state which number percent of theoretical density are based upon--that is, ''2.62 g/cc = 100 percent,'' or ''2.55 g/cc = 100 percent.'' For the convenience of those working… more

FORMATION OF TRANSURANIUM ISOTOPES IN POWER REACTORS

Description: In recent years there has been an increased interest in the use of transuranium isctopes for special power applications. Moreover, as the civilian power reactor economy expands, a large quantity of such isotopes will be formed in reactors using slightly enriched uranium fuel and, more particularly, in reactors which recycle the higher isotopes they form. This report, consisting mainly of computer printouts, indicates the yields of transuranium isotopes from different fueling methods. Since wate… more

Research and Engineering Operation, N-Reactor Department monthly record report

Description: The reactor was manually scrammed from 3870 Mw on January 4 due to a rupture suspect. The failure was subsequently identified as a fretting type on the inner surface of a single tube test fuel element. The evidence indicates that a buggy spring support vibrating against the inner spring of the fuel caused the clad perforation. The remaining column of single tube fuel was discharged. The reactor operated at 3730 Mw until January 7, when the loss of instrument air supply caused the reactor to scr… more
