Experimental results show the sensitivity of hydrodynamically generated vertical loads to changes in the drywell pressurization rate, downcomer submergence, and vent-line loss coefficient. Insignificant effects on peak vertical loads were observed when the vent-line loss was varied. Peak vertical loads can be reduced by adding initial drywell overpressure so that the downcomers are partly cleared of water. Spatial variation of pressure at about the time of vent clearing is seen in comparisons of data from locations along the axis of the toroidal wetwell.

The 236-Z canyon contains equipment for repurification of plutonium and recovery of plutonium from scrap material. To meet production requirements of Fast Flux Test Facility/Clinch River Breeder Reactor oxide with the existing plant, several new pieces of equipment will be needed in the future. More storage space and a better accountability system are needed to support this increased production. The available canyon space needs to be utilized to its fullest in order to accommodate the new equipment. The purpose of this document is to identify the new pieces of equipment, show how they fit into the flowsheet, and locate them in the canyon.

Triaminotrinitrobenzene (TATB) bonded with a copolymer of chlorotrifluoroethylene and vinylidene fluoride (Kel-F 800) was selected as the high explosive for use in the B77 bomb. The plastic-bonded explosive (RX-03-BB, 7.5 percent Kel-F 800) has high strength and is less sensitive to shock initiation than most previously used high explosives. Adhesive bonding of RX-03-BB has proved to be difficult, however, because of the chemical composition of both the TATB and the binder. Studies of the critical surface tension of the TATB, the binder, and the RX-03-BB using contact-angle measurements were made. Surface-tension measurements were made on modified epoxies and used as a guide in formulating new adhesives. A new adhesive, EXPLOSTIK 473, has a surface tension less than RX-03-BB and has satisfactory bond strength to over 75/sup 0/C.

It has been shown that there are three distinct phases of radiosensitivity in oocytes of prepubertal mice: a period of rapidly increasing sensitivity between 0 and 4 days of age; a period of consistent, high sensitivity between 5 and 18 days of age; and a period of decreasing sensitivity from 19 to at least 21 days of age. Two distinct phases have been demonstrated for the rate of population decline of the oocytes of primary follicles: an initial period of rapid loss from 0 to 4 days of age; and a period of much slower loss from 5 through 23 days of age. Correlations have been drawn between the first two phases of radiosensitivity and morphological changes in the oocyte, and between the third phase of radiosensitivity and endocrinological changes in the maturing animal. The reaction of oocytes to radiation has been separated into two categories: immediate death (within 24 hours); and delayed death (over the entire lifespan of the animal). (auth)

In 1976, DOE (FEA) sponsored the development of a systematic methodology for the identification and analysis of candidate projects which a utility might undertake to improve baseload unit reliability. This methodology also enabled the user to estimate a project's effect on the future performance of the unit. A project was sponsored in Illinois to demonstrate the methodology and to encourage increased power plant productivity in the state. A total of 8 improvement projects were conducted and analyzed at Illinois Power Company Wood River 5 and Commonwealth Edison Company Quad Cities 1 and 2 units. A general description of the approach followed in estimating costs and benefits and in presenting the results for the 8 projects is provided. A brief technical description of the projects and their total cost, total benefits, net present value, and benefit-to-cost ratio is given. Detailed cost and benefit summaries for each project are presented followed by a discussion of the results.

We propose a 50-100,000 photo exploratory exposure of the 14{prime} BC filled with {approx}30% Neon, 70% H{sub 2}, to a broad band {bar {nu}} beam produced by whatever intensity ({approx}> 10{sup 12}) IP/pulse and energy ({approx}> 200 GeV) external proton beam is initially available. The Ne-H{sub 2} mixture permits {approx}10 x higher event rate than pure H{sub 2}; also direct detection of {gamma}, K{sub 2}{sup o}, n; better {mu}{sup {+-}}, e{sup {+-}} identification and the possibility of coherent production reactions from the nucleus as a whole as well as incoherent reactions from both neutrons and protons. The event rate vs. E{sub {bar {nu}}} and q{sup 2} will be measured to {approx}130 GeV permitting (in comparison with HBC experiments) estimate of the A dependence of {sigma}{sub T}, and (given crude flux estimates) tests of scaling and locality in d{sup 2}{sigma}/dE{sub {bar {nu}}}dq{sup 2} and {sigma}{sub T} as well as comparison of {sigma}{sub T} on n and p and of these with corresponding {nu} cross sections. Cross sections, particle momenta, invariant mass and angular correlation spectra will be measured for dominant channels permitting crude tests of {Delta}I = 1, {Delta}I = 1/2, {Delta}S = {Delta}Q, {Delta}S {ne} 2 rules.

This report discusses an AP190L array processor (manufactured by Floating Point Systems of Beaverton, Oregon) interfaced to a PDP-10 (Digital Equipment Corporation, Maynard, Mass.). After AP software installation, an analysis of the overhead was performed. The results of these measurements and some conclusions are presented. An AP monitor and software interface were written to minimize the overhead from the PDP-10. A vector extension to the FORTRAN language called FIVE was developed to increase user access to the AP. Some of the problems associated with defining and implementing FIVE are discussed. Its successes and limitations are reviewed. 2 figures, 2 tables.

Data collected as part of the hydrogeochemical and stream sediment reconnaissance for Enid NTMS quadrangle in Oklahoma including laboratory data on well water (pp. 1-14) and stream sediments (pp. 15-24) as well as field data (pp. 25-330).

Growth of channel catfish (Ictalurus punctatus) and Tilapia zillii in the Reft River Geothermal Area (RRGT) geothermal waters can equal or surpass that in a commercial aquaculture facility. Fish and prawn mortality over the course of the intermediate term preliminary study did not appear to be related to any inherent geothermal water chemistry conditions. Temperature control was a problem but does not appear to be beyond design control. The absence of temperature-related mortality in channel catfish, Tilapia zilli, and yellow perch (Perca flavescens) indicates increased survival and suggests reduced expenditures for disease control. It may also allow higher fish densities in commercial aquaculture operations using geothermal water. Results of this study indicate potential for commercial aquaculture development at the Raft River Geothermal Testing Site.

S>Some recent results from the Los Alamos program in which hydraulic fracturing is used for the recovery of geothermal energy are discussed. The location is about 4 kilometers west and south of the ring fault of the enormous Jemez Caldera in the northcentral part of New Mexico. It is shown that geothermal energy may be extracted from hot rock that does not contain circulating hot water or steam and is relatively impermeable. A fluid is pumped at high pressure into an isolated section of a wellbore. If the well is cased the pipe in this pressurized region is perforated as it is in the petroleum industry, so that the pressure may be applied to the rock, cracking it. A second well is drilled a few hundred feet away from the first. Cold water is injected through the first pipe, circulates through the crack, and hot water returns to the surface through the second pipe. Results are described and circumstances are discussed under which artiflcial geothermal reservoirs might be created in the basaltic rock of Hawaii. (MCW)
