A cryogenic system design for the international thermonuclear experimental reactor (ITER)
A conceptual design for ITER was completed last year. The author developed a suitable cryogenic system for ITER as part of this conceptual design effort. An overview of the design is reported. Emphasis is on the fact that cryogenics is a mature science, and a system supporting ITER needs can be made from time-proven components without loss of efficiency or reliability. Because of the large size of the ITER cryogenic system, large numbers of compressors and expanders must be used. Very high reliability is assured by arranging these components in parallel banks where servicing of individual components can be done without interruption of operations. This and other ideas based on the author's experience with Mirror Fusion Test Facility (MFTF) operations are described. 5 refs., 3 figs.

[Letter from Bill McCarter to Gail Davitt, September 25, 1995]
Photocopy of a letter from Bill McCarter, co-director of North Texas Institute for Educators on the Visual Arts, to Gail Davit. In regards of scheduling a two-week summer institute at the Dallas Museum of Art teachers in the Dallas Independent School District. McCarter is hoping that the DMA could provide a laboratory for the fellows to have a "capstone" experience that would benefit the DMA, NTIEVA, DISD and the Marcus Foundation from such a collaboration. An issue McCarter addresses is finding the money to pay the teachers for attending, possibly a shared cost between the district and NTIEVA, he ends the letter saying many details have to be worked out. A cover sheet is at the end of the faxed letter.

Numerical simulation of the stability in a cable-in-conduit conductor developed for fusion-magnet applications
The stability margins of the US-Demonstration Poloidal Coil (US-DPC) and the International Thermonuclear Experimental Reactor (ITER) TF coils have been modeled numerically using the computer program CICC. The computed US-DPC limiting current, I{sub lim}, compares favorably with the values determined experimentally. Using the detailed program CICC output, we investigated the DPC quench initiation mechanism in each of the three stability regions. In the ill-cooled region, the imposed heat pulse heats the conductor to the current-sharing temperature, T{sub cs}. In the transition region, the resistance heating after the pulse must be strong enough to overcome the induced flow reversal. In the well-cooled region, good heat transfer heats the helium during the pulse. After the pulse, these high helium temperatures along with poor heat transfer cause the conductor to quench. Changes in I{sub lim} agree with Dresner's relationship. I{sub lim} can be improved by decreasing the copper resistivity, the helium fraction, or the conductor diameter. Preliminary results show the ITER and TF coil operating point is in the well-cooled region. 10 refs., 7 figs., 1 tab.

Current drive and heating systems for an ITER HARD option
A conceptual design has been developed for a reference current drive and heating system for a HARD (High Aspect Ratio Design) option for ITER. Twelve neutral beam modules, each rated at 1.3MeV and 9.2MW, perform plasma heating and current drive. An electron cyclotron system is used for initiating the plasma and for disruption control. An alternate system has been defined which is comprised of a lower hybrid and ion cyclotron system for heating and current drive, augmented by the same electron cyclotron system proposed for the reference system. 7 refs., 8 figs., 1 tab.

New tools using the hardware performance monitor to help users tune programs on the Cray X-MP
The performance of a Cray system is highly dependent on the tuning techniques used by individuals on their codes. Many of our users were not taking advantage of the tuning tools that allow them to monitor their own programs by using the Hardware Performance Monitor (HPM). We therefore modified UNICOS to collect HPM data for all processes and to report Mflop ratings based on users, programs, and time used. Our tuning efforts are now being focused on the users and programs that have the best potential for performance improvements. These modifications and some of the more striking performance improvements are described.

Staff management of security personnel at Martin Marietta Energy Systems, Inc. , Portsmouth Gaseous Diffusion Plant
The Portsmouth Gaseous Diffusion Plant Security and Police Operations Department is responsible for protecting the US Department of Energy interests at the Portsmouth Plant from theft, sabotage, and other hostile acts that may adversely affect national security, the public health and safety, or property at the Department of Energy facility. This audit's purpose was to evaluate Martin Marietta Energy Systems, Inc.'s staff management at the Portsmouth Plant Security Department. The Portsmouth Plant Security Department could reduce operating cost up to an estimated $4.4 million over 5 years by: (1) Eliminating up to 14 unnecessary staff positions, and (2) reducing the length of relief breaks. These economies could be realized through implementing written operating procedures and negotiating removal of certain labor union restrictions. 2 tabs.

NFS, Kerberos, and UNICOS
The Network File System (NFS) is used in UNIX-based networks to provide transparent file sharing between heterogeneous systems. Although NFS is well-known for being weak in security, it is widely used and has become a de facto standard. This paper examines the user authentication shortcomings of NFS and the approach Sandia National Laboratories has taken to strengthen it with Kerberos. The implementation on a Cray Y-MP8/864 running UNICOS is described and resource/performance issues are discussed. 4 refs., 4 figs.

Low energy ion-molecule reactions and chemiionization kinetics
Our research program is devoted to understanding the dynamics of elementary ionic collisions at the level of the underlying potential surface by measuring energy and angular distributions of reactively scattered products with crossed beam methods over the relative center-of-mass energy range from 0.3 to several eV. We have performed reactive and non-reactive scattering studies on the proton and hydrogen atom transfer systems listed below: O + NH{sub 3} {yields} OH + NH{sub 2} {delta}H = {minus}0.2 eV O + H{sub 2}O {yields} OH + OH {delta}H = +0.4 eV. In both of these systems, the reactions are hypothesized to occur on potential energy surfaces having two minima. The first minimum corresponds to the formation of an electrostatically bound complex, e.g., O(H{sub 2}O), followed by an intramolecular hydrogen atom/proton transfer to yield OH{center dot}OH, which may then form the products by cleavage of the complex.

Equilibrium ammonium concentration in slurry mix evaporator condensate tank (SMECT) with ammonia scrubbers
During design reviews of the Recycle Colection Tank (RCT) at the Savannah River Site it was determined that in all cases the RCT scrub solution could not be routed to the RCT. During transfers to the tank farm (estimated ten hour cycle), the ammonia evolved from the RCT is scrubbed by the RCT scrubber and the ammonia scrub water must be returned to the SMECT. The result of this is an increased steady state concentration of ammonium in the SMECT water used for the ammonia scrubbers. The maximum ammonium concentration is necessary for the sizing of the ammonia scrubbers for the Sludge Receipt and Adjustment Tank (SRAT),Slurry Mix Evaporator (SME), and RCT.

Nitrogen availability as a control mechanism of secondary succession within a semiarid shrubland ecosystem
Three experiments were conducted within a semiarid shrubland to test the role of nitrogen availability as a control mechanism in secondary succession. Secondary succession patterns were documented for seven years and effects of increased and decreased N availability levels, fumigation, and competition by early-seral species were tested. Differential responses by seral species were determined and related to successional patterns. Nitrogen availability was found to be a primary mechanism controlling the rate of succession. Relative growth rate was an important factor determining which species initially dominated and N availability became the primary control factor by the third year. As N availability increased, the rate of succession decreased. Conversely, as N availability was decreased, the rate of succession increased. The abundance of annuals was increased and abundance of perennials decreased by increased N availability. Tissue N concentration was related to lifeform and seral position, and these relationships were important in the transition from early- to mid-seral stages. Decomposer subsystem dynamics were correlated with seral community dynamics. The effect of fumigation was minimized by initially planting with late-seral species. A conceptual model of secondary succession is presented based on N availability, relative growth rate, lifeform, and decomposition dynamics.
