Area Monitoring Dosimeter Program for the Pacific Northwest National Laboratory: Results for CY 1999 (open access)

Area Monitoring Dosimeter Program for the Pacific Northwest National Laboratory: Results for CY 1999

In January 1993, PNNL established an area monitoring dosimeter program in accordance with Article 514 of the DOE Radiological Control Manual. This program was to minimize the number of areas requiring issuance of personnel dosimeters and to demonstrate that doses outside Radiological Buffer Areas are negligible. In accordance with 10 CFR Part 835.402 (a)(1)-(4) and Article 511.1 of the DOE Standard Radiological Control, personnel dosimetry shall be provided to 1) radiological workers who are likely to receive at least 100 mrem annually and 2) declared pregnant workers, minors, and members of the public who are likely to receive at least 50 mrem annually. Program results for calendar years 1993-1998 confirmed that personnel dosimetry was not needed for individuals located in areas monitored by the program. A total of 123 area thermoluminescent dosimeters (TLDs) were placed in PNNL facilities during calendar year 1999. The TLDs were exchanged and analyzed quarterly. All routine area monitoring TLD results were less than 50 mrem annually after correcting for worker occupancy. The results support the conclusion that personnel dosimeters are not necessary for staff, declared pregnant workers, minors, or members of the public in these monitored areas.

Assessment of Concrete Repair Techniques for Radiologically Contaminated Tank Farm Pump and Valve Pits (open access)

Assessment of Concrete Repair Techniques for Radiologically Contaminated Tank Farm Pump and Valve Pits

As part of the scope of Project W-314, ''Tank Farm Restoration and Safe Operations,'' the condition of pump and valve pit walls and floors is being assessed, and repairs made as needed, to support upgrading the infrastructure necessary to safely transfer tank waste for treatment. Flaws in the surfaces of the pits (e.g., concrete crack/faults, protective coating deterioration) must be repaired to ensure containment integrity and to facilitate future decontamination of the pits. This engineering study presents a cost/risk/benefit evaluation of concrete and protective coating repair methods in pump and valve pits using various manual and remote tool systems.

CALDERON COKEMAKING PROCESS/DEMONSTRATION PROJECT (open access)

CALDERON COKEMAKING PROCESS/DEMONSTRATION PROJECT

This project deals with the demonstration of a coking process using proprietary technology of Calderon, with the following objectives geared to facilitate commercialization: (i) making coke of such quality as to be suitable for use in hard-driving, large blast furnaces; (ii) providing proof that such process is continuous and environmentally closed to prevent emissions; (iii) demonstrating that high-coking-pressure (non-traditional) coal blends which cannot be safely charged into conventional by-product coke ovens can be used in the Calderon process; (iv) conducting a blast furnace test to demonstrate the compatibility of the coke produced; (v) demonstrating that coke can be produced economically, at a level competitive with coke imports; and (vi) applying the Calderon technology to making additional iron units. The activities of the past quarter were focused on the following: (1) Bethlehem Steel's withdrawal and efforts expended to substitute U.S. Steel for Bethlehem; (2) Assessment work performed with U.S. Steel to show that the Calderon Technology has merit and would add to U.S. Steel's economic benefit by being involved in it, including for making additional iron units; (3) Addressing material selection and heat input capacity to increase heat input into the processing reactor by actual modeling of such approach; (4) Construction …

Confinement and flavor symmetry breaking via monopolecondensation (open access)

Confinement and flavor symmetry breaking via monopolecondensation

We discuss dynamics of N=2 supersymmetric SU(n_c) gaugetheories with n_f quark hypermultiplets. Upon N=1 perturbation ofintroducing a finite mass for the adjoint chiral multiplet, we show thatthe flavor U(n_f) symmetry is dynamically broken to U(r) times U(n_f-r),where r\leq [n_f/2]is an integer. This flavor symmetry breaking occursdue to the condensates of magnetic degrees of freedom which acquireflavor quantum numbers due to the quark zero modes. We briefly comment onthe USp(2n_c) gauge theories. This talk is based on works with GiuseppeCarlino and Ken Konishi, hep-th/0001036 and hep-th/0005076.

Cosmic Ray Pitch Angle Scattering Through 90{degree} (open access)

Cosmic Ray Pitch Angle Scattering Through 90{degree}

The authors study the problem of cosmic ray diffusion in the galactic disk with particular attention to the problem of particle scattering through the {theta} = cos{sup {minus}1} ({nu}{sub {parallel}}/{nu}) = 90{degree} pitch angle in momentum space by wave-particle mirror interaction (here {nu}{sub {parallel}} is the cosmic ray velocity parallel to the average galactic magnetic field). They consider the case in which cosmic rays are the only source of magnetic turbulence, which originates as the relativistic particles try to stream through the interstellar plasma faster than the local Alfven speed. The wave growth rate is proportional to the cosmic ray anisotropy and the amplitude of hydro-magnetic waves generated by this streaming instability is limited by the presence of various damping mechanisms. They study the propagation of cosmic rays in the different phases of the I.S.M., in particular the coronal regions (where the main form of wave dissipation is non-linear Landau damping) and the warm regions (where charge exchange between the ions and the neutral atoms gives rise to the dominant form of wave dissipation). They also account for ion-cyclotron damping of small wavelength waves. The effect of a spectrum of waves is to limit the anisotropy of the cosmic ray …

Drinking Water: Spending Constraints Could Affect States' Ability to Meet Increasing Program Requirements

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the states' roles in implementing the Safe Drinking Water Act, focusing on: (1) how the Environmental Protection Agency's (EPA) budget requests for state program implementation compared to the amounts that are authorized and estimated to be needed; (2) how much the states have spent since the passage of the 1996 amendments to implement their drinking water programs and how their expenditures compare with estimated needs; (3) what effects federal funding levels have had, and could have in the future, on the states' ability to implement their programs; and (4) what existing practices have the potential to help the states implement their drinking water programs more effectively and efficiently."

An Expression Template Aware Lambda Function (open access)

An Expression Template Aware Lambda Function

The authors show how the paradigms of lambda functions and expression templates fit together in order to provide a means to increase the expressiveness of existing STL algorithms. They demonstrate how the expression templates approach could be extended in order to work with built-in types. To be portable, their solution is based on the Portable Expression Template Engine (PETE), which is a framework that enables the development of expression template aware classes.
