The complete semiannual R and D report consists of this summary and two companion reports, one from DUN which covers reactors and another from ARHCO which covers separations. These companion reports are listed in the set of references in the back of this summary. This semiannual report covers progress in R and D during the first half of FY 1970. Development work on the Basic Production and Product Flexibility Programs has been consistent with funding levels. Increased emphasis has been placed on N Reactor operational problems as well as on assessing the K reactor inlet cooling piping integrity and zirconium hydriding problems. Work has been in progress to improve the Purex plant extraction performance by in-plant testing of the Zirflex Tonic effect. Developmental work was under way to establish either enriched uranium or nondefense plutonium (or both) as a reactor fuel and to provide further technology for the production of high-purity plutonium-238. Activities on the Environmental and Regulatory Technology Program are engaged in developing technology to assure safe operation of the Hanford project facilities. Major emphasis was placed on the study of metal-water (irradiated N fuels) reactions to simulate loss of coolant conditions. Increased emphasis has been placed on the …

Two 250-pound batches of LX-09 were made for BAECP for special studies. Twenty Micronizer runs were made to ascertain the effects of various fluids and wetting gents upon the stability of high surface area PETN and to establish the limits within which repeatability can be expected. One sample, after being treated with the wetting agent dodecyl sodium sulfate, stabilized at 7,400 cm{sup 2}/gm after the 300-hour bake at 100 C. A study was begun to determine the effects of deaeration upon the rheological and firing properties of Extex. Rheological data indicate that deaeration has little effect on extrudability. Firing data are currently being obtained.

This project is for experimentally determining the detonation pressure, etc., of explosives. The detonation pressure of several sizes of PBX 9404 charges was determined using the aquarium technique. Pressure data (from the larger shots) were generally in good agreement with the quoted values for PBX 9404 in these geometries. The small unconfined charge pressure values were consistently about 6% below the accepted 375 kbar value. Experimental shock velocity and computed pressure data are reported.

(Explosives are studied.) Impurities in FEFO and relatively pure FEFO fractions are being obtained by preparative gas chromatography. Use of gas chromatography-mass spectrometry to identify the impurities in FEFO was not successful. Gas chromatography analysis of gas samples taken from the coupon test are reported. Analysis from the third compression type coupon test is reported. The LX-09 lost some of its mechanical strength and was a dark purple. Some of the problems of measuring sample temperature in the high pressure DTA are discussed. DTA thermograms at ambient and elevated pressures are reported for FEFO, nitromethane, Na{sub 3}PO{sub 4}{center_dot}10 H{sub 2}O, and NH{sub 4}H{sub 2}PO{sub 4}.

A factorial spark gap detonator study is presented, with the results. UK PETN, (MF 81/10, 6,200 cm{sup 2}/g) at 1.12 g/cm{sup 3} had a higher voltage breakdown and a higher power deposition than others in the test. A somewhat unusual firing system employed for these tests is described. The purpose of the experiment was for determining the effect of specific surface areas (or particle sizes), density, and energy input (including rate of energy input) upon various dependent variables.

The 48-inch detonation sphere confined the gaseous products resulting from the discharge of approximately one-half pound (225 g) of an HE (PETN) under investigation. Product analysis, combined with calorimetric measurements will provide data regarding the detonation processes. Results of the initial HE detonation are still in the process of evaluation and tabulation. The final summary of this information will be instrumental in the direction of future experimental endeavor. Investigation at Pantex will be in collaboration with and guided by the research in progress at LRL. A new lid, still in the design stage, must be fabricated to make the detonation sphere compatible with the anticipated need in the testing of future explosives. This will necessitate the modification of the vacuum lines, but the extent of this modification is not known at this time.
