Appropriations are one part of a complex federal budget process that includes budget resolutions, appropriations (regular, supplemental, and continuing) bills, rescissions, and budget reconciliation bills. This report is a guide to one of the 13 regular appropriations bills that Congress passes each year. It is designed to supplement the information provided by the House and Senate Appropriations Subcommittees on Legislative Branch Appropriations.

This technical report is a summary of the progress made for �A Guidance Document for Kentucky�s Oil and Gas Operators�. During this quarter, the document received continued review and editing in an elec-tronic format to satisfy the United States Department of Energy (DOE). Comments received from oil and gas operators reviewing this document prompted contact to be made with the United States Environmental Protection Agency (USEPA) to develop an addendum section to provide better explanation of USEPA requirements for Class II injection wells in Kentucky.

Cobalt-free La(Ni,Sn)_5+x alloys have been identified as low cost, corrosion resistant electrodes for nickel-metal-hydride batteries. The structure of theses alloys are similar to non-stoichiometric La(Ni,Cu)_5+x compounds; i.e., they retain the P6/mmm space group while Ni dumbbells occupy La sites. Electrodes fabricated from some of these novel alloys have capacities and cycle lives equivalent to those made from commercial, battery grade, AB₅ alloys with cobalt.

A systematic study of the etch characteristics of GaN, AlN and InN has been performed with boron halides- (BI{sub 3} and BBr{sub 3}) and interhalogen- (ICl and IBr) based Inductively Coupled Plasmas. Maximum etch selectivities of -100:1 were achieved for InN over both GaN and AlN in the BI{sub 3} mixtures due to the relatively high volatility of the InN etch products and the lower bond strength of InN. Maximum selectivies of- 14 for InN over GaN and >25 for InN over AlN were obtained with ICl and IBr chemistries. The etched surface morphologies of GaN in these four mixtures are similar or better than those of the control sample.

The void fraction instrument (WI) was deployed in Tank 241-SY-101 three times in 1998 to confm and locate the retained gas (void) postulated to be causing the accelerating waste level rise observed since 1995. The design, operation, and data reduction model of the WI are described along with validation testing and potential sources of uncertainty. The test plans, field observations and void measurements are described in detail, including the total gas volume calculations and the gas volume model. Based on 1998 data, the void fraction averaged 0.013 i 0.001 in the mixed slurry and 0.30 ~ 0.04 in the crust. This gives gas volumes (at standard pressure and temperature) of 87 t 9 scm in the slurry and 138 ~ 22 scm in the crust for a total retained gas volume of221 *25 scm. This represents an increase of about 74 scm in the crust and a decrease of about 34 scm in the slurry from 1994/95 results. The overall conclusion is that the gas retention is occurring mainly in the crust layer and there is very little gas in the mixed slurry and loosely settled layers below. New insights on crust behavior are also revealed.

This report summarizes the technical progress achieved during the first quarter of the ERIP project entitled, ``Laser Ultrasonic Furnace Tube Coke Monitor.`` The focus of work during this reporting period was the testing of a novel device for introducing a broad bandwidth ultrasonic pulse at the surface of a simulated furnace tube. The device employs a sacrificial stand-off composed of a fusible alloy that conforms to hot furnace tube surface upon contact. Conventional high-temperature couplants have a maximum operating temperature of about 550{degrees}C, which limits their use for contact against ethylene cracker furnace tube surfaces that typically operate at about 1000{degrees}C. In the absence of a couplant, insufficient ultrasonic energy can be transmitted from the transducer to the tube surface. By using a fusible alloy, the device efficiently couples the transducer to the hot furnace tube surface, even for rough and convex tube surfaces operating at temperatures of 1800{degrees}F and above. Initial tests confirmed the ability to resolve pulse echoes in a simulated furnace tube using a 5 MHz piezoelectric transducer with a fusible stand-off.

This document is a revision and update to the initial report that describes various leak detection, monitoring, and mitigation (LDMM) technologies that can be used to support the retrieval of waste from the single-shell tanks (SST) at the Hanford Site. This revision focuses on the improvements in the technical performance of previously identified and useful technologies, and it introduces new technologies that might prove to be useful.

Planar targets illuminated by the Petawatt laser system emit directed beams of photons with energies of MeVs. The laser pulses have durations of 0.5 or 5 psec, on target energies in excess of 100 joules, and focal-spot sizes that vary from 10 to 100 µm, producing peak intensities greater than 10¹⁹ watts/cm^;2. Arrays of PIN diodes, dosimeters and nuclear-activation detectors measure the angular distributions of photons with energies greater than 0.5 MeV. The PIN diodes, with 1 cm² by 500-µm sensitive volume, are housed in lead pigs with 2.5-cm thick walls. Measured emission intensities have been as high as 5x10¹³ (gamma) MeV/steradian. The angular distributions are highly directed in forward directions, with significant variations on a shot-to-shot basis. Backward radiated intensities tend to be more than a decade lower than in forward direct

Nanometer-scale compositional structure in InAsxP1.InNYAsxPl.x-Y/InP, grown by gas-source molecular-beam epitaxy and in InAsl-xPJkAsl$b#InAs heterostructures heterostructures grown by metal-organic chemical vapor deposition has been characterized using cross-sectional scanning tunneling microscopy. InAsxP1-x alloy layers are found to contain As-rich and P-rich clusters with boundaries formed preferentially within (T 11) and (111) crystal planes. Similar compositional structure is observed within InNYAsxP1-x-Y alloy layers. Imaging of InAsl-xp@Asl#bY superlattices reveals nanometer-scale clustering within both the hAsI-.p and InAsl$bY alloy layers, with preferential alignment of compositional features in the direction. Instances are observed of compositional structure correlated across a heterojunction interface, with regions whose composition corresponds to a smaller unstrained lattice, constant relative to the surrounding alloy material appearing to propagate across the interface.
