Changes to the Computer Code and Data Collection

CCC-544/CEPXS/ONELD 1.0

Experimental and Mathematical Physics Consultants, Gaithersburg, Maryland, contributed a newly compiled PC version of CEPXS/ONELD 1.0. The Lahey Fortran 90 Compiler release 4.50i was used to create the included PC executables that can be run under either Windows XP or Windows 2000.  Executables in the previous release were compiled with F77L-EM/32 Fortran compiler, Version 5.01, and are incompatible with current Windows operating systems.

This code system was originally developed at Los Alamos National Laboratory, Los Alamos, and Sandia National Laboratory, Albuquerque, New Mexico. CEPXS generates cross sections to be input to ONELD, a one-dimensional coupled electron-photon transport code.  ONELD is a discrete ordinates code that uses linear-discontinuous spatial differencing and diffusion-consistent weighted diamond angular differencing. The equations are solved via source iteration with S 2 synthetic acceleration of the inner iterations. References: SAND89-1685 (October 1989), SAND89-1661 (September 1989), LA-9184-M, Rev. (December 1989), SAND89-2211 (July 1990). Fortran 77; VAX, Cray, and PC 586. The VAX version includes a few lines of C. All of these versions are distributed on one CD as C00544MNYCP02.

PSR-481/TRAC PF1

For archival purposes, RSICC is releasing a PC version of TRAC PF1, which performs best estimate analyses of loss-of-coolant accidents and other transients in pressurized light water reactors. The program can also be used to model a wide range of thermal hydraulic experiments in reduced scale facilities. Models employed include reflood, multi-dimensional two-phase flow, nonequilibrium thermodynamics, generalized heat transfer, and reactor kinetics. Note that the NRC no longer supports the TRAC codes but currently develops and maintains the TRACE code system, which is the TRAC/RELAP Advanced Computational Engine.

TRAC-PF1 was developed on a CDC computer at Los Alamos National Laboratory in the 1980s. The PC version of TRAC PF1 was converted at Comissao Nacional de Energia Nuclear (CNEN), Rio de Janeiro, RJ (Brazil). It was submitted September 1989 and released as is by the ESTSC July 1993; it was later transferred to RSICC and re-released in November 2005 for archival purposes. No modifications were made to the code package at either ESTSC or RSICC. Records indicate that the PC version ran on an 80386 PC under DOS 3.2 using the SVS (Silicon Valley Software) Fortran 77 compiler. No executables are included in the package. The package is transmitted on a CD-ROM in a WinZIP file, which includes Fortran source, sample problems, control information, and auxiliary information. References: NUREG/CR-3567 (LA-9944-MS) (February 1984), NUREG/CR-3280 (LA-9704-M) July 1983, and LA-TIA-TN-82-1 (June 1982). Fortran 77 for IBM PC XT and AT (P00481IBMPC00).

News to Note

Francis Kam, 76, died November 15, 2005. He was a scientist at Oak Ridge National Laboratory for more than 20 years and made significant contributions to the American Society for Testing and Materials. He also made important contributions to various international activities sponsored by the International Atomic Energy Agency and the United States Nuclear Regulatory Commission. In the early to mid 1960s Frank was involved in the development and documentation of several computer codes (including O5R) used for neutron transport.  He and Kylene Franz developed a code named ACTIFK to analyze the collision tapes from the O5R computer code which wrote user selected types of events such as boundary crossings and real collisions to a tape for later analysis. He was also involved in calculations of the SNAP reactor shielding benchmarks.

Graydon Duane Whitman died December 3, in Knoxville, Tennessee. Grady was a Manhattan Project veteran of ORNL, arriving in 1944 through an Army Corps of Engineers assignment. He went on to become an operations supervisor on the Aircraft Reactor Experiment, the forerunner of the Molten Salt Reactor. He managed and participated in a number of seismic analyses of gaseous diffusion plants and managed the Experimental Gas Cooled Reactor activities at ORNL.

Professor Tatiana Tanya Anotolievna Germogenova, April 10, 1930 February 27, 2005

We regret the passing of Tatiana Germogenova, an authoritative scientist in the field of mathematical study of the linear transport equation. She was also investigations organizer, originator and manager of the Linear Transport Theory Group of the Keldysh Institute of Applied Mathematics (KIAM) of the Academy of Sciences. She is best known to RSICC for the many ways she sought to open lines of communication between the scientific communities of our respective countries, while under the former Soviet Union and continuing into the Russian era. She died in Moscow February 2, 2005.

Germogenova began working on transport theory problems in a post graduate course in the Physical Department of Moscow State University under Prof. E.S. Kousnetsov. In 1956, she joined the KIAM staff. Her PhD thesis (1972) was dedicated to boundary problems of the transport equation and local properties of its solutions.

The important cycle of Germogenovas work deals with actual problems of atmospheric optics. She proved that the set of physically realizable states of polarized light in the Stokes-Poincare representation is a cone in an appropriate functional space of 4-dimensional vector-functions (1978). This property was used for strict formulation of both the non-negativity property of the scattering matrix and the mathematical theory of the characteristic equation for the polarized light transport equation. She also derived the set of asymptotic approximations for transport problems in optically thick inhomogeneous finite size regions (1961).

Germogenovas results in the study of the method of averaged fluxes for acceleration of inner iterations convergence (1968-1969), Fourier analysis of stability of the WDD scheme, accuracy and stability analysis of the family of weighted nodal schemes (1994), and eigenfunctions of the finite moments method analysis (1996) are interesting and important. Under her guidance, a set of Russian codes (ROZ, ROZ-W, RADUGA, KASKAD-S and KATRIN) were developed for 1D, 2D, and 3D transport calculations for a serial computer. Much of her work was classified, not in the public domain but was recognized in 1987 when she was awarded the Soviet State Prize.

Prof. Germogenova participated in a number of international meetings on transport theory, was co-organizer of the Joint Workshop on Numerical Transport Theory (November 1961) at Texas A&M University in College Station, Texas, and the International Symposium on Numerical Transport Theory (May 1992) at Moscow State University, Moscow, Russia. She was also a member of the Transport Theory and Statistical Physics Editorial Board.

Germogenova is followed as Manager of KIAM Linear Transport Group by her colleague and friend, Dr. Andrei M. Voloschenko (volosch@kiam.ru).

Germogenova was versatile student swimming titleholder at MSU, expert skier, boating and mountaineer enthusiast and a connoisseur of classical music. She is survived by her husband, Yuri Dnestrovski, a Professor at MSU. Both he and her son are plasma physicists associated with the TOKOMAK at Kurchatov Institute. Her daughter is a hydrobiologist. She is also survived by four grandchildren, two of whom are students at Moscow State University.

NCRP 2006 Annual Meeting,
Chernobyl at Twenty

The National Council on Radiation Protection and Measurements (NCRP) will hold its 2006 Annual Meeting April 34, at the Crystal City Marriott in Arlington, Virginia. The April 26, 1986, accident at the Chernobyl nuclear power plant near Kiev in the Ukrainian Republic of the Former Soviet Union was the worst nuclear power accident in history. Large numbers of people were contaminated in the Ukraine Republic, Belarus Republic, Western Russia, Western Europe, and Scandinavia. More than 200,000 people in the Ukraine and Belarus Republics were evacuated and resettled as a result of significant fallout from the Chernobyl accident.

On the twentieth anniversary of this disastrous event, the 2006 NCRP Annual Meeting will provide a comprehensive retrospective review and analysis of the effects of the Chernobyl nuclear accident on human health and the environment. Topics to be discussed by international experts include:

        the initial release, distribution and migration of radiation from Chernobyl;

        efforts to clean up, contain and dispose of radionuclides released by the accident;

        health effects observed in emergency responders and cleanup workers;

        exposures and health effects among populations living close to, and distant from, the Chernobyl reactor site;

        lessons learned from the Chernobyl accident, including improved nuclear safety procedures, better preparedness for future nuclear accidents, and more effective management and mitigation of human health consequences of such events; and

        international perspectives on the future use of nuclear technology and nuclear power in comparison with other power sources.

The program and registration for the meeting can be accessed at http://www.ncrponline.org/dates.html.

TRAINING COURSE ON NEUTRON SPECTRA UNFOLDING

This two-day training course on neutron spectra unfolding will be held April 78, 2006, in Cape Town, South Africa. The training course is organized by the Neutron Radiation department of the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany. Additional support is provided by EURADOS. The course is intended for those who do spectrometry in neutron or mixed neutron/photon fields and need to analyze their data using unfolding procedures; emphasis is on practical aspects of unfolding.

A series of lectures in the morning sessions will provide an introduction to unfolding as well as allow for discussions on the theory of unfolding. In the afternoon sessions participants will work on specific examples at PC-workplaces using the UMG software package provided by PTB (UMG: Unfolding with GRAVEL and MAXED, currently distributed by NEA as code package NEA-1665 and by RSICC as code package PSR-529). We will focus on Bonner sphere measurements for our discussion of few-channel unfolding, and on liquid scintillation spectrometer (NE213) measurements for our discussion of multi-channel unfolding.

The number of participants will be restricted due to the limited number of PC-workplaces available. Therefore, you should register as soon as possible. For on-line registration and further information please visit the website at:  http://www.ptb.de/utc2006/. Contact: Burkhard Wiegel, PTB, email Burkhard.Wiegel@ptb.de  The fee for the course is 800 Euro and includes a CD with a complete set of notes and unfolding software, as well as refreshments.

PRACTICAL MCNP FOR THE HP, MEDICAL PHYSICIST, AND RAD ENGINEER

DATES: 1721 July 2006 (4.5 days)

FEE: $1,450 per person

PLACE: The MESA Complex, Room 130, University of New Mexico-Los Alamos Campus

Monte Carlo type calculations are ideally suited to solving a variety of problems in radiation protection and dosimetry. The Los Alamos MCNP code is a general and powerful Monte Carlo transport code for photons, neutrons, and electrons, and can be safely described as the industry standard. This course is aimed at the HP, medical physicist, and rad engineer with no prior experience with Monte Carlo techniques. The focus is almost entirely on the application of MCNP to solve a variety of practical problems in radiation shielding and dosimetry. The intent is to jump start the student toward using MCNP productively. With a little practice and study of the examples, many will find they are able to solve problems that have, in the past, been out of reach.

Course content: Extensive interactive practice sessions are conducted on a personal computer. Topics will include an overview of the MCNP code and the Monte Carlo method, input file preparation, geometry, source definition, standard MCNP tallies, interpretation of the output file, exposure and dose rate calculations, radiation shielding, photon skyshine, detector simulation and dosimetry. Students will be provided with a comprehensive class manual and a diskette containing all of the practice problems. This course has been granted 32 Continuing Education Credits by the AAHP (2005-00-003), and 4.5 CM points by the American Board of Industrial Hygiene. The course is offered by the Health Physics Measurements Group at the Los Alamos National Laboratory.

Registration is available online at: http://drambuie.lanl.gov/~esh4/mcnp.htm. Make checks (U.S. dollars on a U.S. bank ) payable to the University of California and mail with name, address, and phone number to: David Seagraves, Mail Stop J573, Los Alamos National Laboratory, Group HSR-4, MCNP Class, Los Alamos, NM 87545.
