This report presents details of the activities of Douglas United Nuclear at the Hanford site during the month of June 1969.

Progress on the gas-cooled reactor program is reported. Separate abstracts were prepared for each of the 14 sections. (M.C.G.)

This is the monthly report for the Hanford Laboratories Operation June 1962. Reactor fuels, chemistry, dosimetry, separation processes, reactor technology, financial activities, biology operation, physics and instrumentation research, operations research and synthesis, programming, and radiation protection operation are discussed.

From introduction: "The basic interactions which give rise to the interesting magnetic properties of dilute alloys, such as cobalt in palladium, have received a great deal of attention both theoretically and experimentally. This problem has many facets which are peculiarly interrelated. For example, there is the problem of Curie points of the order of magnitude of 10°K for concentrations of 'magnetic' ions of 0.1%. It has been proposed that this problem involves virtual d-states (Friedel) which permit one to understand much of what is observed."

A test was made to determine the over-all effects of reduced coolant purification on the reactor plant. The effects were increased specific activity, gross gamma activity, and fission product activity of the reactor cooling system. (W.L.H.)

A review is presented on vapor-liquid equilibria. Arnong the topics discussed are activity coefficients, consistency criteria, automatic computation, and gaseous mixtures. A bibliography of 18 references is included. (D.L.C.)

A FORTRAN program is presented for processing pulse-height data for particles emitted from a nuclear reaction. The program corrects the particle energy for any absorber preceding the detector and computes the differential center-of-mass cross section as a function of the reaction Q value and the excitation energy of the final nucleus. The energies can be computed either relativistically or nonrelativistically. The program is written as a series of subroutines to facilitate possible expansion of the program and to allow easy accommodation of different data input routines. The output of the program is printed in tabular form and, at the discretion of the user, punched on cards for off-line plotting or for input to other programs. (auth)

The objective of this test are: (1) to operate two single pass tubes in the 1706-KE in-reactor facility using water treated in the water treatment pilot plant, (2) to obtain samples of effluent water, and (3) to obtain corrosion measurements from weighed fuel, dummies, and coupons.

The hot-die-sized concept has been under investigation as an alternate manufacturing process for several years. Irradiation testing of the elements began in mid 1963. Some dimensional behavior problems were encountered with the fuel and a test is now being irradiated which may provide sufficient data to remedy the situation. Pre-irradiation examination of fuel elements has shown a significant dimensional change of the cores during the fabrication process, and this dimensional change is thought to contribute to the irradiation behavior of the elements. The irradiation effects of fabrication parameters that influence the dimensional. The objective of the test detailed in this is to evaluate the effects of end bonding pressure and machined core size on the irradiation characteristics of hot-die-sized diffusion bonded fuel elements.

>The corrosion resistance of mantensitic and ferritic austenitic stainless steels and carbon steels in pressurized water at 500 to 600 deg F is compared. Included are specific out-of-pile data for austenitic stainless steels, AISI types types 410, 420, 431, and 440C; the ferritic AISI types 430, 442, and 446; the precipitation-hardening type 17-4PH; and carbon steels, ASTM 212 A and B. Available corrosion results obtained under irradiation at exposures in the range of 7 x 10/sup 16/ to 3 x 10/sup 19/ nvt are also included for types 304, types of martensitic and ferritic stainless steels which were evaluated do not contain nickel. For application where it is desirable to minimize Co/sup 58/ activity produced from nickel, selection of a martensitic or ferritic stainless steel may be more appropriate than choosing the more popular nickel-bearing austenitic stainless steel or a fuel-element cladding material. Interpretation of the data indicates that, on the average, martensitic and ferritic stainless steels corrode more rapidly than austenitic alloys but more slowly than carbon and low-alloy steels. Under selected controlled water conditions or under irradiation, the corrosion of the nickel-free stainless steels appears to differ little from the austenitics. The corrosion of martensitic and ferritic stainless …

The four experimental through-tubes provided in the Experimental Gas Cooled Reactor will extend directly through the core of the reactor and penetrate both the upper and lower pressure vessel heads. Each tube is anchored in an upper head nozzle and the bottom end is allowed to slide in a lower head nozzle. This lower nozzle is basically a T'' section that provides bottom access to the through-tube and a side access for the piping which connects the throughtube to the experimenter's cell. Due to differential thermal expansion of the through- tubes relative to the reactor pressure vessel, vertical movement of the through- tube within the T'' section will be experienced. At the same time a horizontal thrust applied to each tube by thermal expansion of the piping to the experimental cell will result in metalto-metal contact between each tube and the lower T'' section. Tests were conducted on three types of bearing material proposed for use on the through-tubes and T'' sections to minimize galling which can be expected to occur. Stellite No. 12 has been demonstrated to be an adequate bearing material for the intended application. (auth)
