UT-Battelle Takes the Reins

April 1, 2000, was the official start date of the UT-Battelle contract with the U. S. Department of Energy to operate Oak Ridge National Laboratory. New Laboratory Director, Bill Madia, had this to say on the occasion:

"This is an exciting day for me and the members of the UT-Battelle leadership team. We are honored to begin a partnership with the Department of Energy and the outstanding staff at Oak Ridge National Laboratory. The partnership is one we believe will be mutually beneficial for years to come. ORNL is one of the world's finest research and development facilities. Working with you and the Department of Energy, UT-Battelle's goal will be to enhance the Lab's capabilities and improve the quality of life for its employees. The transition period served to reaffirm our belief that success will depend upon achieving simultaneous excellence in science and technology, laboratory operations and ES&H, and community service. Based upon what we learned, our agenda for ORNL will focus on four basic initiatives.

"First, we must pursue every opportunity to grow the Lab's portfolio. Second, we must broaden ORNL's partnerships and be viewed as a highly valued asset among the Lab's stakeholders. Third, we must update the facilities at ORNL if we are to continue to attract and retain world class scientists. Finally, in large and small ways we must reduce the cost of doing business within the Lab. We view each of these initiatives as priorities essential to the Lab's future."

Area Code Changes for RSICC

This is it. Your last chance to change the programming for your phone calls to RSICC. The area code for parts of East Tennessee changed from 423 to 865 effective November 1, 1999. April 24, 2000, is the last day on which both area codes can be used.

NRC Codes Made Available

Several U.S. Nuclear Regulatory Commission (NRC) software packages which were transferred from the ESTSC to RSICC were incorporated into the RSICC computer code collection. Please browse the computer code abstracts available at RSICC's www site for more information on these packages.

PSR-482/REMIT 3.5


Two changes were made to the computer code collection during the month. One new code system was added and one code system was corrected. One change resulted from a foreign contribution.

Synthesis Srl and ENEL, SpA in Milano, Italy, through the OECD NEA Data Bank, contributed this code system for best estimate coupled 3D neutronics-thermalhydraulics calculations. TRAC-PF1-EN/MOD3 is a combined computer program comprising a revised version of the TRAC-PF1 transient reactor analysis code and a specially implemented three-dimensional two-group neutron kinetics code (QUANDF). Starting from either a critical steady-state or a subcritical steady-state in a PWR plant, the code allows one to simulate the neutronic and thermal-hydraulic core transient response to reactivity accidents initiated both inside and outside the vessel.

The present version of TRAC-PF1-EN/MOD3 is intended for use on a personal computer but, with some changes, it has also been tested on a UNIX workstation (IBM Power PC-RISC system 6000/250) and on a mainframe (IBM system 9021/832). The MS Fortran Power Station Compiler version 1.0 or higher can be used under DOS 6.0 or WINDOWS 95. The Digital Visual Fortran v.5.0 was used to create an executable included in the package. The package is transmitted on CD-ROM which contains the Fortran source files and executable, code manual, and the input/output files for the three sample problems in a self-extracting, compressed DOS file. Reference: Rep. 1037/3 (February 1997). Fortran 77; PC 486 (P00477PC48600).

Los Alamos National Laboratory, Los Alamos, New Mexico, contributed a new version of this code system for producing pointwise and multigroup neutron and photon cross sections from ENDF/B data. NJOY is a modular computer code used for converting evaluated nuclear data in the ENDF format into libraries useful for applications calculations. Because the Evaluated Nuclear Data File (ENDF) format is used all around the world (e.g., ENDF/B-VI in the U.S., JEF-2.2 in Europe, JENDL-3.2 in Japan, BROND-2.2 in Russia) NJOY allows access to a wide variety of the most up-to-date nuclear data. NJOY99 is a cleaned up version of NJOY 97.107 that features improved consistency between different systems, more use of block structures, a consistent set of physical constants and support for the CCC-700/MCNP4C Monte Carlo Program, which will soon be released.

NJOY99 runs on many computers. Machine-specific updates are included for Cray, Sun, IBM RS/6000, SGI Origen 2000, and DEC Alpha workstations, plus Linux and DOS updates for PC. This version was tested on a Sun Ultra in 32-bit mode using f77 and f90, on a Pentium III using linux g77 and Portland Group, Inc. Fortran, on a SGI Origen 2000 using f90, and on a Pentium III under DOS with Lahey LF95 and Absoft compilers. UPD and NJOY99 executables created with the Lahey F95 v5.5d compiler under WindowsNT 4 are included in the package. All Unix systems require a Fortran compiler. The distribution includes the NJOY99 and UPD source codes, PC executables, updates, makefiles, selected ENDF/B data sets for test cases, sample problem input and output. The package is transmitted on CD-ROM in both tar and DOS formats. References: "README0" (December 31, 1999), LA-12740-M (October 1994), LA-12639-MS (ENDF 356) (March 1994), LA-12057-MS (April 1991). Fortran 90 or Fortran 77; Cray, Sun, IBM RS/6000, PC/Linux, PC/DOS (P00480/MNYCP/00).


One new data library was added to the collection during the month.

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed this package to compute radiological decay and daughter ingrowth using the DLC-172/NUCDECAY data library. The utility code DecayCalc extracts the decay data from the library for radionuclide(s) specified by the user and computes the activities of radionuclides present after decay and ingrowth over a user-specified time period from 1 minute to 50 years. Decay data for any decay chain may be displayed and printed either in tabular form or graphically. Radionuclide information is available through the help system, including decay tables and graphics and dose factors. DecayCalc, in a slightly modified version, will be a part of CCC-553/Rascal V3 to be released later this year.

The unabridged data used in preparing ICRP Publication 38 are distributed in electronic form in this package. The collection consists of data on the energies and intensities of radiations emitted by the 825 radionuclides reported, although abridged, in ICRP Publication 38 plus an additional 13 radionuclides evaluated during preparation of a monograph for the Medical Internal Radiation Dose (MIRD) Committee of the Society of Nuclear Medicine.

DecayCalc is a Windows application that runs under Microsoft Windows 95 or 98, or Microsoft Windows NT 4.0 or later. The Compac Fortran 77 compiler was used to compile the code. The full source for DecayCalc is not provided but will be distributed when Rascal v3 is released.

Included are the referenced document and a CD written in Windows format which includes the data library, the installation code, and the utility code. Reference: Informal user guide (March 2000). Fortran; Pentium running Windows 95/98/NT (D00202PC58600).


RSICC has lost many friends and colleagues within the international radiation shielding community. However, it is with great sadness that we report the death of one of our own.

Constance Marie Anthony, 72, of Oak Ridge, died Thursday, March 30, 2000, at her home. Marie began her association with RSIC (Radiation Shielding Information Center; now RSICC) in 1969 as an information specialist. She retired from the Center in 1990. In the intervening years she managed the testing and packaging of pending codes/data systems and the reproduction of the codes/data documentation.

Marie at her retirement party with, from left to right: husband, William, Henrietta Hendrickson, Robert Roussin, Marie, and her "twin sister" Carol Coker.

The following are excerpts from Marie's obituary:

Born June 25, 1927 in Nashville, she was the daughter of Albert and Emma C. Hyde Bell. She worked briefly as a teacher in Georgia before coming to Oak Ridge in the early 1950s. Prior to her work at ORNL, she taught kindergarten and third grade at the old Scarboro Elementary School and was an adult education instructor at Oak Ridge High School and ORNL. She also previously worked at ORTEC. Mrs. Anthony was a co-founder of Spurgeon Chapel AME Zion Church in Oak Ridge, where she played the piano and organ for the church choir. She is survived by two sons, Darryl Anthony and his wife, Deborah, and Michael Anthony and his wife, Melissa; a daughter, Denise Anthony; and four grandchildren. Her husband, William Bright Anthony, died Aug. 25, 1992.

    Reactor Analysis and Criticality Safety Short Courses

    The Department of Nuclear Engineering at the University of Tennessee-Knoxville is offering two short courses for radiation transport specialists during Tennessee Industries Week (TIW-35), August 14-18, 2000.

    Monte Carlo Analysis is often the method of choice to solve complex problems in criticality and radiation shield design. The transport analyst must often choose between Monte Carlo and deterministic methods like discrete ordinates; or the nature of the design problem may dictate that he perform a coupled (Monte Carlo/discrete ordinates) calculation. Therefore, to use Monte Carlo and other transport methods effectively, the analyst must understand the theoretical and computational fundamentals. Rather than use an existing program, it is sometimes advantageous to create a new special-purpose Monte Carlo program. The procedures that are involved in preparing a user-written Monte Carlo program will be described in terms of the classical and conceptually simple straight-ahead, one-speed, slab transmission problem.

    Many advanced topics will be included that will permit optimum use of existing computer codes such as MCNP. Special attention will be given to the understanding of the adjoint calculation. Advantages and disadvantages of the adjoint mode versus the forward mode of analysis will be described. The full range of variance reduction techniques will be studied for both forward and adjoint calculations.

    The Monte Carlo Method offers the expectation that the true solution to the problem as modeled can be achieved. However, this may lead to a false sense of credibility, in particular when calculations are performed by relatively inexperienced users (the majority of people who use the Monte Carlo method do so only occasionally). Monte Carlo calculations are subject to major errors and/or misinterpretations because currently used statistical measures may be insufficient. Other methods for statistically characterizing Monte Carlo methods will be described.

    The relationship of the Monte Carlo method to the other transport methods such as discrete ordinates will be described, including comparisons of computational advantages and disadvantages. The MCNP computer code will be described as required to illustrate the general features of large Monte Carlo computer programs.

    Nuclear Criticality Safety Engineers, scientists, and technical managers who wish to increase their knowledge and understanding of nuclear criticality safety will be interested in this intensive one-week short course. The topics covered in the course are based primarily on the experience of the six instructors which totals over 130 years of nuclear criticality safety related experience. Such a wealth of experience needs to be shared with the criticality safety community including both new professionals in the field as well as experienced professionals.

    The course topics include illustrative applications using the SCALE system developed at Oak Ridge National Laboratory with emphasis on the Monte Carlo code KENO Va, standards, regulations, review of accidents, hand calculation methods, subcritical limits, code validation techniques, emergency response, process upsets and recovery actions, and transient excursion modeling.

    The registration fee is $1195 per person for each course. The deadline for registration in these courses is August 1, 2000. For additional information contact Lydia Salmon, Dept. of Nuclear Engineering, University of Tennessee, Knoxville, TN 37996 (phone 865-974-2525; email lutne@utk.edu).
