Improving Contract Performance by Corrective Actions Plans
Corrective Action Plans (CAPs) are required to be developed, submitted, and reported upon by the prime contractors for the U.S. Department of Energy (U.S. DOE) Management and Operations (M and O) contracts. The best known CAP ''type,'' and there are many, is for Price-Anderson Amendments Act (PAAA) ''potential noncompliances.'' The M and O contractor fines for PAAA problems have increased from approximately $100,000 in 1996 to almost $2,000,000 in 2000. In order to improve CAP performance at the National Nuclear Security Administration (NNSA) site at Y-12 in Oak Ridge, Tennessee, the contractor chose to centralize the company-wide processes of problem identification and reporting with the PAAA (and other) CAP processes. This directly integrates these functional reports to the contractor General Manager. The functions contained in the M and O contractor central organization, called ''Performance Assurance,'' are: PAAA; Defense Nuclear Facilities Safety Board (DNFSB) Liaison; Contract Requirements Management; Issues Management (including the CAP processes); Lessons Learned; Independent and Management Assessments; Internal Audits; and Ethics. By centrally locating and managing these problem identification and problem correction functions, the contractor, BWXT Y-12, L.L.C., has improved PAAA (and other) CAP performance more than 200 percent in the first year of the contract. Much of …

Strangeness production in heavy ion collisions: What have we learned with the energy increase from SPS to RHIC
A review of strange particle production in heavy ion collisions at ultrarelativistic energies is presented. The particle yields and ratios from SPS and RHIC are discussed in view of the newest developments in understanding collision dynamics, and in view of their role in the search for a quark gluon plasma. A strangeness enhancement, most notably observed in CERN Pb-beam results, shows a remarkable two fold global enhancement with a much larger effect seen in the case of multistrange baryons. Hadronic models did fail to explain this pattern. At RHIC energy strangeness assumes a different role, since temperatures are higher and the central rapidity region almost baryon-free. An intriguing question: ''Did RHIC change the way we understand strangeness production in heavy ion collisions ?'' is discussed.

Non-additive sputtering of niobium and tantalum as large neutral and ion clusters.
An analysis of available literature data on both the positive ion emission from Nb and Ta bombarded by 6 keV/atom Au{sub m}{sup -} atomic and molecular ions (m=1, 2, 3) and positive ionization probabilities of Nb{sub n} and Ta{sub n} neutral clusters sputtered from the same metals by 5 keV Ar{sup +} ions have been conducted. Dependencies of cluster yields Y{sub n,m} (regardless of a charge state) on number of atoms n in a sputtered particle were found to follow a power law as Y{sub n,m} {approx} n{sup -{sigma}{sub m}} where {sigma}{sub m} decreased with an increase of m. A non-linear enhancement of yields for large Nb{sub n}{sup +} and Ta{sub n}{sup +} cluster ions (n>4) appeared to be due to a non-additive process of sputtering rather than because of a non-additive process of their ionization. A manifestation of the non-additive sputtering in kinetic energy distributions of secondary ions found to be different for atomic and cluster ions.

Expanding Ring for the DWPF Melter Pour Spout
The Materials Technology Section was requested to develop a novel concept, namely that of an expanding ring, to restore the upper knife edge in the DWPF melter pour spout. The expanding ring is a unit that, when deployed in the DPWF pour spout, will self-expand against the inner diameter of the 3-inch section of the pour spout providing a seal against glass leakage and a new knife edge that will mate with a Type 3A insert. This report provides a summary of the final design features of the expanding ring and an overview of its development.

Demonstration of the Tank Farm Washing Process and the DWPF SRAT Cycle with Sludge Batch 3 Simulant and Precipitated Pu/Gd Mixture from H-Canyon Tank 18.3
The Nuclear Materials Management Division (NMMD) has proposed that certain Pu solutions stored in H-Canyon be disposed to H-Tank Farm. These solutions contain significant inventories of plutonium. The Pu/Gd mixture (along with the sludge slurry from Tank 7 and Am/Cm solution) will be processed as a part of Sludge Batch 3. Sludge Batch 3 is the next sludge batch of feed for the Defense Waste Processing Facility (DWPF). In order to prepare the feed for DWPF, the sludge slurry will be washed to approximately 0.55 M Na in the supernate. This report addresses the glove box work with a Sludge Batch 3 simulant and a Pu/Gd mixture precipitated from H-Canyon Tank 18.3. The main objective of this experimental work was to determine the behavior of the Pu and Gd during the Tank Farm washing process and the SRAT process.

Thermal and Chemical Stability of Baseline and Improved Crystalline Silicotitanate
The Savannah River Site (SRS) has been evaluating technologies for removing radioactive cesium ({sup 137}Cs) from the supernate solutions stored in the high-level waste tanks at the site. Crystalline silicotitanate (CST) sorbent (IONSIV IE-911{reg_sign}, UOP LLC, Des Plaines, IL), which is very effective at removing cesium from high-salt solutions, was one of three technologies that were tested. Because of the extremely high inventory of {sup 137}Cs expected for the large columns of CST that would be used for treating the SRS supernate, any loss of flow or cooling to the columns could result in high temperatures from radiolytic heating. Also, even under normal operating conditions, the CST would be exposed to the supernates for up to a year before being removed. Small-scale batch and column tests conducted last year using samples of production batches of CST showed potential problems with CST clumping and loss of cesium capacity after extended contact with the simulant solutions. Similar tests-using samples of a baseline and improved granular CST and the CST powder used to make both granular samples-were performed this year to compare the performance of the improved CST. The column tests, which used recirculating supernate simulant, showed that the baseline CST generated more …

RESRAD connection for facilitating MARSSIM analysis : an illustration of applying the OpenLink concept.
The focus of this work is to more tightly integrate tools traditionally used in MARSSIM (Multi-Agency Radiation Survey and Site Investigation Manual) final status survey design. MARSSIM provides guidance on appropriate methodologies for establishing that dose or risk-based standards for a site contaminated with radionuclides have been achieved. RESidual RADioactive (RESRAD) codes are used by the U.S. Department of Energy, the U.S. Nuclear Regulatory Commission, and other federal agencies to convert dose-based cleanup criteria to site-specific-derived concentration guideline level (DCGL) requirements. By implementing MARSSIM concepts directly within RESRAD, users can now directly generate site-specific DCGL requirements and associated area factors.

Integrated seismic studies at the Rye Patch Geothermal Reservoir, Nevada
A 3-D surface seismic reflection survey, covering an area of over 3 square miles, was conducted at the Rye Patch geothermal reservoir (Nevada) to explore the structural features that may control geothermal production in the area. In addition to the surface sources and receivers, a high-temperature three-component seismometer was deployed in a borehole at a depth of 3900 ft within the basement below the reservoir, which recorded the waves generated by all surface sources. A total of 1959 first-arrival travel times were determined out of 2134 possible traces. Two-dimensional ray tracing was performed to simulate wave propagation from the surface sources to the receiver at depth. Travel time differences between observed and calculated times were mapped to topographic changes in the elevation of the interface between the carbonate basement and the sedimentary and volcanic unit above. Results indicate the presence of two dominant geologic features. The first confirms the regional trend of the geologic units in the Basin and Range province with a north-south strike and dip to the west, as expected for normal faulting encountered in an extensional regime. The second is a local disturbance of this regional pattern in form of an elevation of the interface between the …

A new method for x-ray fluorescence analysis of contaminated material. Final Report
Niton has successfully completed the objectives of the Phase II program to build a hand-held, x-ray fluorescent analyzer optimized for DOE decontamination and decommissioning activities in the field. A two-pound x-ray fluorescence analyzer was developed that contains 3 radioactive sources, emitting 3 widely spaced monochromatic x-rays, to give the lowest detection limits for the full range of toxic elements, from chromium to plutonium. A rapid, fundamental- parameters algorithm was developed that yields quantitative results in less than 1 second. High-resolution silicon drift detectors and silicon PIN diodes give excellent efficiency and speed. These results from Phase II have been introduced into the XL 300, 700 and 800 commercial products series. More than 800 of these instruments, yielding revenues of more than $20 million dollars, have been sold since the first 3-source instrument was introduced in 1998. A direct consequence of the Phase II funding has been the growth of Niton from 20 people to its present size of 60.

Report of Snowmass 2001 working group E2: Electron - positron colliders from the phi to the Z
We report on the status and plans of experiments now running or proposed for electron-positron colliders at energies between the {phi} and the Z. The e{sup +}e{sup -}B and charm factories we considered were PEP-II/BABAR, KEKB/Belle, superKEK, SuperBABAR, and CESR-c/CLEO-c. We reviewed the programs at the {phi} factory at Frascati and the proposed PEP-N facility at Stanford Linear Accelerator Center. We studied the prospects for B physics with a dedicated linear collider Z factory, associated with the TESLA high energy linear collider. In all cases, we compared the physics reach of these facilities with that of alternative experiments at hadron colliders or fixed target facilities.

Measured Winter Performance of Storm Windows
Direct comparison measurements were made between various prime/storm window combinations and a well-weatherstripped, single-hung replacement window with a low-E selective glazing. Measurements were made using an accurate outdoor calorimetric facility with the windows facing north. The doublehung prime window was made intentionally leaky. Nevertheless, heat flows due to air infiltration were found to be small, and performance of the prime/storm combinations was approximately what would be expected from calculations that neglect air infiltration. Prime/low-E storm window combinations performed very similarly to the replacement window. Interestingly, solar heat gain was not negligible, even in north-facing orientation.

PDII- Additional discussion of the dynamic aperture
This note is in the nature of an addition to the dynamic aperture calculations found in the report on the Proton Driver, FERMILAB-TM-2169. A extensive discussion of the Proton Driver lattice, as well as the nomenclature used to describe it can be found in TM-2169. Basically the proposed lattice is a racetrack design with the two arcs joined by two long straight sections. The straight sections are dispersion free. Tracking studies were undertaken with the objective of computing the dynamic aperture for the lattice and some of the results have been incorporated into TM-2169. This note is a more extensive report of those calculations.

A modular optics design for the NuMI beamline
The Nu MI beamline discussed here is a modular optics design, characterized by 4 sections: MI {yields} beamline matching; periodic FODO cells; a special insertion to traverse the carrier pipe, and a versatile final focus section to produce the desired spot-size on the target. The use of 21 quadrupoles ensures that beam size is constrained within acceptable bounds throughout the line--{beta} < 60 m in the MI matching section & FODO cells, {beta} < 125 m in the doublets of the carrier pipe insertion, and {beta} < 100 m in the final focus. Lattice functions of the NuMI design are not unusually sensitive to errors arising either from MI optical mismatches or gradient errors, and are completely correctable through the 2 matching sections. Aperture studies indicate that the line is able to transport the worst quality beam that the Main Injector might provide. Dipole correctors at 19 of the 21 focusing centers are available to provide high-quality orbit control & further ensure that the NuMI line meets the stringent requirements for environmental protection.

Modeling of liquid metal duct and free-surface flows using CFX.
Liquid metal free-surface flows provide an option of a renewable surface for heat absorption, removal of impurities, and eliminating the problems of erosion and thermal stresses [1], [2]. In a tokamak liquid metal flows through a strong magnetic field, which results in a magnetohydrodynamic (MHD) interaction. For a free-surface flow the MHD interaction may be even more important than for the duct flows in blankets, because the electromagnetic forces may significantly deform the free-surface and thus make it unfavorable for heat extraction. The MHD-related problems for the free-surface flows have been reviewed in [3]. Among the most important ones are the effects of nonuniform magnetic fields, inertia, surface tension, wettability and roughness of walls on both the jet/drop shape and trajectory. The main problems for the jet divertor are shown in Figure 1 and Figure 2 [4]. Particular issues related to some of the problems listed in these figures have already been tackled (Problem 1 in [5]-[7], 4 in [8], [9], 5 in [9], 6 in [4], 7 and 10 in [9], 9 in [10]). Once main fundamental aspects for each of these sub-problems are understood, the analysis will have been performed for a particular divertor design.

Unusual interlayer transport in quasi-two-dimensional organic metals.
The interlayer transport properties of the organic superconductor {beta}{double_prime}-(ET){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3} are presented. The resistivity perpendicular to the highly conducting ET layers is about 100 times larger than compared to other quasi-two-dimensional ET salts. For a magnetic field parallel to the layers no peak could be resolved in the angle-dependent interlayer resistance which proved the coherent nature of transport in other ET salts. This and the absence of any further clear-cut proof for a coherent quasiparticle motion suggest an incoherent nature of the interlayer transport in {beta}{double_prime}-(ET){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3}.

Non-Abelian gauge theory on q-Quantum spaces
Gauge theories on q-deformed spaces are constructed using covariant derivatives. For this purpose a ''vielbein'' is introduced, which transforms under gauge transformations. The non-Abelian case is treated by establishing a connection to gauge theories on commutative spaces, i.e. by a Seiberg-Witten map. As an example we consider the Manin plane. Remarks are made concerning the relation between covariant coordinates and covariant derivatives.
