Water quality considerations - Project Travois

Description: The technical concept for Project Travois contains one simple analysis of the potential hazard of contaminating the Arrowrock Reservoir on the Boise River with some of the radionuclides produced. This previous analysis assumes homogeneous and prompt mixing of all the tritium and tungsten isotopes. This simple analysis is physically unrealistic sine there is no way of transporting all of these radionuclides to the reservoir, promptly. We shall in this paper reanalyze the contamination problem in such a way that we define the type of site geology and hydrology information that must be developed.

Mound bridge-wire welding, testing and corrosion seminar, Miamisburg, OH, May 7-8, 1968

Description: Brief summaries are presented on the following presentations: welding for low voltage operation, welding techniques at Mound, welding/joining at Sandia, Ultrasonic`s plastic assemblies of detonator components, laser welding bridge-wires, laser safety in the Biorad industrial environment, nondestructive testing at Mound, thermal cycle data and evaluation, thermal cycle nondestructive testing, corrosion of detonator electrode and bridge-wire, and corrosion studies and fabrication of bridge-wire at Sigmund Cohn.

Oblique impact sensitivity of explosives: The skid test. Quarterly report, April--June, 1968

Description: RX-04-CW, LX-07-1, and RX-09-CD were tested. The RX-04-CW and LX-07-1 are not complete; however, results so far show the TX-04-CW comparable in sensitivity to PBX 9404 while the LX-07-1 is less sensitive at 14{degree}. The RX-09-CD was slightly more sensitive than the RX-09-CB previously tested.

HE formulation. Quarterly report, January--March, 1968

Description: RX-09-CB and LX-07 were made to supply material for testing. Both were made in the 300-gallon kettle in 250-pound batches which were then blended into 1,000-pound lots. An RX-09 with no plasticizer (HMX and DNPA) was made in the 30-liter reactor for special gap and friction studies. Approximately 20 pounds of DNPOH, supplied by Aerojet, was converted to DNPA and polymerized by the emulsion polymerization process. Work on high surface area PETN continued by precipitation recrystallizing two 10 kg batches; one to supply material for detonator applications to Mound Laboratory and the other to supply high surface area PETN to LRL for special applications. Surface area for this batch was 21,200 cm{sup 2}/gm. The detonator material had a surface area of 14,500 cm{sup 2}/gm. A system duplicating the English method for achieving high surface area has been completed with the installation of the 8-inch Micronizer, and two preliminary trials of one pound each have been made. Surface areas were 20,900 and 14,900 cm{sup 2}/gm. The system is being modified slightly to eliminate the problems incurred during these trial runs and preparations are in process for making a 10 kg batch to be shipped to Mound.

A catalog of ideas for underground yield determination

Description: Because of the persistent problem of convenient determination of underground yield, Certain `electromagnetically` oriented ideas in this area are summarized. They all require much more detailed study and evaluation, although one or two of them are inexpensive enough to perhaps warrant an empirical test. Methods discussed are: Vertical sounding of the Ionosphere; The electromagnetic `Magnetic Bubble` scheme; Non-resonant scattering; Resonant scattering; and The gravitational pulse.

Adhesives, fillers and potting compounds. Second progress report, December 1, 1967--April 1, 1968

Description: Progress in the development program whose immediate purpose is to reduce set time of a silicone compound is described. Data are presented showing that a formulation of a current RTV silicone rubber with dibutyltin diacetate has a profitably lower set time than the same rubber in the present formulation which uses dibutyltin dilaurate, without increase in probability of either reversion or penalty to other weapons components. Time to set sufficiently to allow the next assembly step is 2 to 4 hours, compared to the 16 to 24 hours presently allowed or the 8 to 12 hours minimum attainable with the present formulation. The reduction is of the magnitude set as a goal, the attainment of which would increase production capacity enough to reduce the amount of new construction planned to accommodate weapons assembly programs.

Bioenvironmental and radiological-safety feasibility studies, Atlantic-Pacific Interoceanic Canal. Phase 2, Freshwater ecology: Final report

Description: The purpose of this program is to conduct studies in the freshwater environment to acquire data needed to evaluate and predict the potential radiation hazards to human populations in the defined regions of proposed nuclear excavations in the Republics of Panama and Colombia. The results of the field surveys conducted in Phase II are presented in this report. Specifically, the data describes the elemental composition of the major components of the ecosystem, and reports the calculated stable element concentration factors for the major food organisms. This data provides baseline values from which predictions can be made of the potential maximum radionuclide intake by populations using this resource.
