The Columbia River Cooling Program CY-1965
The Columbia River Cooling Program basically consists of effecting a reduction in river temperature at the Hanford site during the summer season. The implementation of this program in recent years has been accomplished through the selective and controlled discharge of waste water at Grand Coulee Dam. The purpose of this report is to describe the river cooling program conducted in CY-1965 by Facilities Engineering personnel, and present the program results.

K Reactor uncooled HCR: Equilibrium temperature study
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 reasonable contact between the graphite stack and the graphite slider plates that will be placed in the bottom of the rod channels prior to rod insertion and use.

NUCLEAR SPECTROSCOPIC STUDIES OF SOME VERY HEAVY ODD-MASS NUCLIDES
The nuclear radiations of nuclides: U{sup 233}, Pu{sup 239}, Bk{sup 243}, Bk{sup 244}, Bk{sup 245}, Bk{sup 246}, Bk{sup 249}, Cf{sup 249}, and Fm{sup 255} were investigated with high-resolution spectrometers. The {alpha}-particle spectra of all nuclides except Bk{sup 249} were measured with 6 mm diameter surface-barrier detectors. Bk{sup 249} {alpha}-particles were analyzed with a double-focusing magnetic spectrograph. The {gamma}-singles were examined with the recently developed Ge(Li) and Si(Li) detectors coupled with very-low noise 'internal FET' preamplifiers. Weak alpha groups were observed in coincidence with {gamma}-rays, detected with a NaI(Tl) scintillation spectrometer. To improve the over-all coincidence efficiency a new coincidence apparatus was designed and built. This instrument consisted of a cooled 4.5 cm diameter semiconductor detector for {alpha}-particle detection and a 3 cm diameter by 2.7 cm long Ge(Li) detector for {gamma}-ray analysis. The Ge(Li) detector could also be replaced with a NaI(Tl) detector. Cf{sup 249} conversion electrons were measured with a cooled Si(Li) detector coupled with an internal FET preamplifier. On the basis of the present work and previous information, energy-level diagrams of the daughter nuclei have been constructed. The levels have been grouped into rotational bands built on Nilsson single-particle states. Because of identification of several rotational members of …

Abstract -- A description of low temperature hydriding of zircaloy at Hanford
The two K Reactors at the Hanford Plant of the Atomic Energy Commission were retubed in 1963 with ribless Zircaloy process tubes. These tubes, 1.81 inch OD x 0.037 inch wall, were made by tube reducing methods from extruded blooms and were installed without final pickling or autoclaving. These tubes are used with once-through filtered water with a maximum coolant temperature of approximately 110 C. After approximately two years` service, it was discovered that these tubes were absorbing hydrogen in a totally unexpected and alarming manner. It was found that the downstream few feet of these tubes had a layer of massive hydride platelets, several mils thick, on the inner surface, and that the hydrogen content of the tube wall beneath this layer had increased from the as-fabricated level of 5--15 ppm to 50--75 ppm. The portion of the tubes so affected was downstream of the fuel charge. Physical testing has indicated loss of ductility but no significant changes in strength, Cold burst tests resulted in a ductile failure mode with no tendency toward brittle fracture. A program to determine the basic mechanism responsible for this phenomenon as well as practical means for its elimination will be the subject of …

Experimental design for the preliminary study of geochemical processes
An example of the use of a simple fuctorial design to study the distribution of /sup 134/Cs and/sup 85/Sr between a soil column and solution is reported. In this design, two concentration levels of each of four factors (NaNO/ sub 3/, HNO/sub 3/, KNO/sub 3/, and Ca(NO/sub 3//sub 2/) were combined in all possible combiuations to give a total of 24 combinations. In the case of /sup 134/Cs removal, all of the independent variables were significant over their respective concentration ranges, while with the removal of /sup 85/Sr, none of the independent variables was statistically significant. Extending the concentration range of NaNO/sub 3/ caused the NaNO/sub 3/ effect total to become statistically significant at the 5% t-test level in its effects on /sup 85/Sr removal. A fractioral factorial design was used to study the removal of Sr from solutions into an apatite during a chemical reaction between phosphate ion and calcite. The Yates analysis of the Sr removal data is tabulated. It is noted that even at a t-test level of 1%, calcite surface area, influent solution pH. and system temperaturesolution pH interaction are statistically significant. The two-level factorial design yields no direct indication of the Sr removal mechanism but …
