Immigration and Naturalization Service Reorganization and Related Legislative Proposals

Description: The Immigration and Naturalization Service (INS), with a current annual budget of $4.3 billion, is the primary agency charged with enforcing the nation's immigration law. Regulating immigration can be viewed as having two basic components: stemming illegal immigration (enforcement) and facilitating legal immigration (service). The Administration is moving forward to restructure the agency internally by separating the agency's enforcement and service functions, but maintains that the immigration function must be managed by a single executive who can integrate immigration policy, standards, and operations. There is no statutory requirement that the Administration gain Congress's formal approval of its plan to restructure INS. Congress, however, could choose to mandate legislatively that INS be dismantled or restructured differently.

Immigration Legislation and Issues in the 105th Congress

Description: Immigration legislation enacted and considered in the 105th Congress can be divided into three categories: (1) legislation prompted by the major immigration and welfare legislation enacted in the 104th Congress; (2) legislation in response to the expiration dates of existing provisions; and (3) legislation which addressed emerging new issues -- issues that the 104th Congress did not address, or issues that arose since then.

Innovative clean coal technology (ICCT): demonstration of selective catalytic reduction (SCR) technology for the control of nitrogen oxide (NO{sub x}) emission from high-sulfur, coal-fired boilers - economic evaluation of commercial-scale SCR applications for utility boilers

Description: This report presents the results of an economic evaluation produced as part of the Innovative Clean Coal Technology project, which demonstrated selective catalytic reduction (SCR) technology for reduction of NO{sub x} emissions from utility boilers burning U.S. high-sulfur coal. The document includes a commercial-scale capital and O&M cost evaluation of SCR technology applied to a new facility, coal-fired boiler utilizing high-sulfur U.S. coal. The base case presented herein determines the total capital requirement, fixed and variable operating costs, and levelized costs for a new 250-MW pulverized coal utility boiler operating with a 60-percent NO{sub x} removal. Sensitivity evaluations are included to demonstrate the variation in cost due to changes in process variables and assumptions. This report also presents the results of a study completed by SCS to determine the cost and technical feasibility of retrofitting SCR technology to selected coal-fired generating units within the Southern electric system.

Mass Yields From Fission by Neutrons Between Thermal and 14.7 Mev

Description: Radiochemically determined mass-yield curves are given for the fission of U/sup 235/ and U/sup 238/ by l4.7-Mev neutrons. Symmetric and to a less extent, very asymmetric modes of fission are more probable at that energy than in thermal fission. Yields of four fission products from the fission of U/sup 235/ have been measured as a function of neutron energy in the range thermal to 14 Mev. The yields of eleven masses have been measured from the fission of Np/sup 237/ by degraded fission spectrum neutrons. The mass-yield curve is similar to that from the thermal fission of Pu/sup 239/ with a ratio of peak to valley yields of approximately 175. Relative yields of one peak fission product and four valley fission products have been determdned under the following conditions: fission of U/sup 235/ and Pu/sup 239/ with thermal neutrons; fission of U/sup 235/ Pu/sup 239/ and U/sup 238/ with fission spectrum neutrons; and fission of U//sup 235/ and Pu/sup 239/ with the intermediate neutron spectrum at the center of the Los Alamos Fast Reactor. Absolute yields of Moss have been determined from the fission of U/sup 235/,Pu/sup 239/ with thermal neutrons. (auth)

Search for X-Ray Induced Acceleration of the Decay of the 31-yr Isomer 178Hf Using Synchrotron Radiation

Description: Releasing the energy stored in an isomeric nuclear state in a controlled way with an atomic or electromagnetic trigger is an attractive speculation: the energy gain may be on the order of the ratio of nuclear/atomic energies - MeV/keV. (Nuclear isomers are loosely defined as excited nuclear states with lifetimes longer than 10{sup -9} s.) Nuclear isomers, therefore, represent an opportunity for a stand-alone energy source if suitable schemes for trigger and control of the energy release can be found. Potential applications include space drive, as well as very bright {gamma}-ray sources. The nucleus {sup 178}Hf has a nuclear isomer with excitation energy E{sub x} = 2.447 MeV. The 2.447-MeV isomeric state decays slowly (t{sub 1/2} = 31 y) to the nearby state at 2.433 MeV. The J{sup {pi}} = 13{sup -} state loses energy in a rapid (t {approx} 10{sup -12} s) {gamma}-ray cascade ending at the 8{sup -} rotational band head which in turn decays via the ground-state rotational band cascade. The {gamma}-ray cascade is delayed at the 8{sup -} state at 1.147 MeV, since the 8{sup -} state is also isomeric, with t{sub 1/2} = 4 s. Very scarce quantities of the 16{sup +}, 31-yr isomer are available for research ({approx} 10{sup 15} atoms). Reports of triggered decay of the {sup 178}Hf isomer induced by x-rays delivered by a dental x-ray machine have been made [2,3]. Enhancements of {approx} 1 - 2% in the isomer decay rate (dN/dt = - (1 + {var_epsilon})N/{tau}) had been reported for various {gamma}-rays in the cascade (distinguished by red and vertical lines in Figure 1). The reported integrated cross section for triggering the decay is cm{sup 2} keV, so large as to demand new physics. We have sought to verify these reports taking advantage of the intense photon flux available at ...

Coast Guard Polar Icebreaker Modernization: Background and Issues for Congress

Description: This report provides background information and issues for Congress on the sustainment and modernization of the Coast Guard’s polar icebreaker fleet, which performs a variety of missions supporting U.S. interests in polar regions. The Coast Guard’s proposed FY2015 budget requests $6 million to continue initial acquisition activities for a new polar icebreaker. The issue for Congress is whether to approve, reject, or modify Coast Guard plans for sustaining and modernizing its polar icebreaking fleet. Congressional decisions on this issue could affect Coast Guard funding requirements, the Coast Guard’s ability to perform its polar missions, and the U.S. shipbuilding industrial base.

Search for X-ray induced decay of the 31-yr isomer of 178Hf using synchrotron radiation

Description: Isomeric {sup 178}Hf (t{sub 1/2} = 31 yr, E{sub x} = 2.446 MeV, J{sup {pi}} = 16{sup +}) was bombarded by a white beam of x-rays from the Advanced Photon Source at Argonne National Laboratory. A search was made for x-ray induced decay of the isomer by detecting prompt and delayed {gamma} rays associated with the decay. No induced decay was observed. Upper limits for such a process for x-ray energies between 7-100 keV were set. The limits between 7 and 30 keV are below {approx} 3 x 10{sup -27} cm{sup 2}-keV for induced decay that bypasses the 4-s isomer and {approx} 5 x 10{sup -27} cm{sup 2}-keV for induced decay that is delayed through this isomer, orders of magnitude below values at which induced decay was reported previously. These limits are consistent with what is known about the properties of atomic nuclei.
