UTSI/CFFF MHD PROGRAM COMPLETION AND RELATED ACTIVITY
Maintenance work on the DOE CFFF facility and other related government property is no longer authorized under this contract in accordance with the DOE-UT Settlement Agreement. Environmental remediation preservation of the facility continued. Government property has been transferred to UTSI as owner which frees up many items for proper disposal. Actions are underway to dispose of other wastes, and control pests and water at the DOE CFFF. Groundwater remediation activities as mandated by the Tennessee Department of Environment and Conservation (TDEC) continued throughout the quarter. A contract was awarded to an environmental consulting company to drill and sample three additional groundwater wells adjacent to the CFFF property. A report on this activity, with results of the sample analysis, has been sent to the TDEC.

VENTILATION MODEL REPORT
The purpose of the Ventilation Model is to simulate the heat transfer processes in and around waste emplacement drifts during periods of forced ventilation. The model evaluates the effects of emplacement drift ventilation on the thermal conditions in the emplacement drifts and surrounding rock mass, and calculates the heat removal by ventilation as a measure of the viability of ventilation to delay the onset of peak repository temperature and reduce its magnitude. The heat removal by ventilation is temporally and spatially dependent, and is expressed as the fraction of heat carried away by the ventilation air compared to the fraction of heat produced by radionuclide decay. One minus the heat removal is called the wall heat fraction, or the remaining amount of heat that is transferred via conduction to the surrounding rock mass. Downstream models, such as the ''Multiscale Thermohydrologic Model'' (BSC 2001), use the wall heat fractions as outputted from the Ventilation Model to initialize their postclosure analyses.

Very high power THz radiation at Jefferson Lab
We report the production of high power (20 watts average, {approx};1 Megawatt peak) broadband THz light based on coherent emission from relativistic electrons. We describe the source, presenting theoretical calculations and their experimental verification. For clarity we compare this source with one based on ultrafast laser techniques, and in fact the radiation has qualities closely analogous to that produced by such sources, namely that it is spatially coherent, and comprises short duration pulses with transform-limited spectral content. In contrast to conventional THz radiation, however, the intensity is many orders of magnitude greater due to the relativistic enhancement.

Very high power THz radiation sources
We report the production of high power (20 watts average, {approx} 1 Megawatt peak) broadband THz light based on coherent emission from relativistic electrons. Such sources are ideal for imaging, for high power damage studies and for studies of non-linear phenomena in this spectral range. We describe the source, presenting theoretical calculations and their experimental verification. For clarity we compare this source to one based on ultrafast laser techniques.

Visa Issuances: Policy, Issues, and Legislation
This report addresses the current policy on immigration visa issuances and options for reassigning this function to the proposed Department of Homeland Security (DHS). It opens with an overview of visa issuances, with sections on procedures for aliens coming to live in the United States permanently and on procedures for aliens admitted for temporary stays. An analysis of the grounds for excluding aliens follows. The report summarizes the debate on transferring visaissuance policy functions to homeland security and concludes with a discussion of the legislative proposals to reassign the visa issuance activities and to revise visa issuance policies.

Water Conservation Study for Manastash Creek Water Users, Kittias County, Washington, Final Report 2002.
Manastash Creek is tributary of the Yakima River and is located southwest and across the Yakima River from the City of Ellensburg. The creek drains mountainous terrain that ranges in elevation from 2,000 feet to over 5,500 feet and is primarily snowmelt fed, with largest flows occurring in spring and early summer. The creek flows through a narrow canyon until reaching a large, open plain that slopes gently toward the Yakima River and enters the main stem of the Yakima River at river mile 154.5. This area, formed by the alluvial fan of the Creek as it leaves the canyon, is the subject of this study. The area is presently dominated by irrigated agriculture, but development pressures are evident as Ellensburg grows and develops as an urban center. Since the mid to late nineteenth century when irrigated agriculture was established in a significant manner in the Yakima River Basin, Manastash Creek has been used to supply irrigation water for farming in the area. Adjudicated water rights dating back to 1871 for 4,465 acres adjacent to Manastash Creek allow appropriation of up to 26,273 acre-feet of creek water for agricultural irrigation and stock water. The diversion of water from Manastash Creek …

Withdrawal from the ABM Treaty: Legal Considerations
On December 13, 2001, President Bush gave formal notice to Russia, Belarus, Kazakhstan, and the Ukraine that the United States was withdrawing from the Anti-Ballistic Missile Treaty because of the constraints it imposes on the testing of missile defense systems; and six months later, on June 13, 2002, the treaty effectively terminated. The ABM Treaty has been in force since 1972. Pertinent legal questions that have been raised about U.S. withdrawal concern whether the treaty allows it; if so, the procedure to be followed; and, finally, the constitutionality of the President doing so unilaterally without the involvement of the Senate or Congress. This report briefly discusses these issues, as well as the recent federal district court decision in Kucinich v. Bush dismissing a suit by 32 members of the House challenging the constitutionality of the President’s action.

The Zintl Chemistry of the Heavy Tetrel Elements
Exploration of the alkali metal/alkaline-earth metal/heavy tetrel (Sn or Pb) systems has revealed a vast array of new chemistry and novel structure types. The structures and properties of these new materials have been studied in an attempt to understand the chemistry of these and other related systems. The first phase reported is Rb{sub 4}Pb{sub 9} (K{sub 4}Pb{sub 9} type). The compound contains two different types of Pb{sub 9}{sup 4-} deltahedra, a monocapped square pyramid and a distorted tricapped trigonal prism. Both cluster geometries correspond to a nido assignment even though the tricapped trigonal prism is not the classic Wade's rules nido deltahedron expected for a monocapped square antiprism. Also, a series of compounds that contain square pyramidal Tt{sub 5} polyanions of tin and lead has been obtained in alkaline-earth or rare-earth metal-tetrel systems by direct fusion of the elements to yield Sr{sub 3}Sn{sub 5}, Ba{sub 3}Pb{sub 5}, and La{sub 3}Sn{sub 5}. These phases contain square pyramidal clusters of the tetrel elements that are weakly interlinked into chains via two types of longer intercluster interactions that are mediated by bridging cations and substantially influenced by cation size and the free electron count. Attempts at incorporating another main-group element to form heteroatomic …
