Enhancing the use of coals by gas reburning-sorbent injection

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on three coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices; tangential, wall, and cyclone fired. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 percent in SO{sub x} emissions, by a combination of two developed tech… more

Inclusive large mass muon pair production in ultra-relativistic nucleus-nucleus collisions for colliding beams

Description: For colliding beams of several species of ions we compare thermal to perturbative quantum chromodynamic contributions for inclusive large mass muon pair production by using a hydrodynamic model to estimate the temperatures of the quark-gluon plasma produced by each species. The production of high energy dimuons with M {approx equal}-4 GeV, will be favored energetically by the quark-gluon plasma. 10 refs., 4 figs., 2 tabs.

Design and modelling of a 5 MeV radio frequency electron gun

Description: The Accelerator Test Facility (ATF) at Brookhaven National Laboratory is a linac-laser complex for research into laser acceleration and for the generation of coherent radiation from electron beams. In order to achieve the design 50 MeV output emittance (..gamma..sigma/sub x/sigma/sub x/') of less than 3 /times/ 10/sup /minus/5/ m rad a high brightness electron gun is required. This paper describes computations and measurements made on a full scale brass model of a 1-1/2 cell, ..pi..-mode, reson… more

The effects of furnace environment on the mechanical properties of vanadium

Description: We have conducted tests to ascertain whether or not exposure to erbia would adversely affect the mechanical properties of vanadium more than the regular annealing furnace environment. Mechanical properties of the vanadium exposed to erbia are not different from those of the vanadium to a regular annealing furnace environment. However, there is a change in the impurity levels, the carbon content increasing and the oxygen content decreasing. There is also anomalous behavior in the strain-hardenin… more

D0 Vent Stacks

Description: There are two nitrogen/argon exhaust headers in the D0 cryogenic piping system, one for the liquid argon dewar and another for the three argon calorimeters. These headers serve two functions, venting both nitrogen exhaust from the cooling loops and cold argon gas should any argon vessel blow a relief. These headers are vacuum jacketed until they exit the building. At that point, uninsulated exhaust stacks direct the flow into the atmosphere. This note deals with the these stacks.

D-Zero End Cap Calorimeter Annular Piping Analysis

Description: In accoradnce with the ASME Code for Pressure Piping, B31 version of Chemical Plant and Petroleum Refinery Piping, ANSI/ASME B31.3-1984 Edition, the maximum allowable stress for 304 stainless steel piping is 25,500 psi. This 'Allowable Displacement Stress Range' value was calculated using equation (1a) found on page 16 of the above mentioned reference. Each of the lines that comprise the End Cap Calorimeter (BC) piping were modeled on ANSYS and the appropriate constraints were applied. This was… more

Conceptual design plans for the FY 1993 line items

Description: This Facilities Capability Assurance Program (FCAP) project provides for the design and construction of a reconfigured production facility(ies) for Mound`s non-nuclear weapons components. Existing buildings would be rehabilitated in order to locate final production/assembly areas within close proximity and in a facility suitable to operations of this nature. Ancillary operations will be located in nearby buildings, also rehabilitated, in order to provide support to final production with minimal… more
