NC State Celebrates!

The following was taken from the February 2001 issue of the ANS Nuclear News.

North Carolina State University celebrated the 50th anniversary on December 2-4, 2000, of both the founding of its nuclear engineering academic program and the beginning of construction of its Raleigh research reactor. The Raleigh unit was designated in 1986 as an American Nuclear Society historical landmark in recognition of its being the first reactor in the world to be operated by a non-governmental institution.

Fifty years after the founding, NC State's academic program is now offered through the school's Department of Nuclear Engineering, and the nuclear reactor program is operating its fourth reactor, the PULSTAR, which in 1997 received a license renewal from the Nuclear Regulatory Commission, allowing it to continue operations for an additional 20 years. 

The Golden Anniversary celebration was a three-day event attended by about 100 participants. During the celebration, Carolina Power and Light Company, operator of four nuclear power plants, was recognized for its $283,000 gift to the Department of Nuclear Engineering. The Golden Anniversary concluded with a remembrance of 18 late faculty members of NC State's nuclear engineering staff and a Letter of Appreciation to Raymond Murray for his 50 years of service to the school's nuclear engineering and reactor programs.

PSR-448/MAR-D 4.16 (distribution is limited to United States)

PSR-453/SEISIM1

PSR-460/OCTAVIA
 

CHANGES TO THE COMPUTER CODE and DATA COLLECTION

Three new packages were added to the computer software and data collection during the month, two of which are foreign contributions.

CCC-698/WIMS-ANL, Version 4.00

Argonne National Laboratory, Argonne, Illinois, contributed the WIMS-ANL code, which is an extension of the Winfrith WIMS-D4 code for lattice cell computations. This code has been tailored to address some of the problem areas encountered in dealing with research reactor fuels, experiment, reflector and control regions. The SUPERCELL option eliminates some of the limitations of the traditional SPECTROX solution and supports the solution of more complex geometries with a more detailed spatial mesh and multiple resonance materials. The code generates both macroscopic and microscopic cross sections in the ISOTXS format with any selected number of energy groups. The user can specify which fission product isotopes are to be explicitly included in the microscopic burnup dependent ISOTXS library. Fission product library data can be generated for use with the MCNP code and burnup dependent applications. The cross section library data provided are based on ENDF/B versions VI (69 group) and V (69 and 172 group) data. The code is variably dimensioned so that other group structures could be used. The source code and output format have been completely revised to reflect current coding practices and to permit display of the results on typical desk top monitors.

The methods of solution in WIMS-ANL remain unchanged from those used in the original WIMS-D4 code with the same resonance treatment and a choice of collision probability and DSN solutions for the simple lattice cell. The SUPERCELL option provides for the selection of supporting auxiliary cells that might represent the different elements and varying spectra of the final SUPERCELL model. The resonance treatment where applicable is carried out in the auxiliary cells. These data are combined in the detailed SUPERCELL computation, and cross section data are generated for the selected edit regions and isotopes.

The code compiled successfully on Sun Solaris; the Lahey compilers F77L, LF90 and LF95 for PC; and the g77 and GNU compilers under Linux. The package is transmitted on a CD rom and includes the source files, scripts, data library, and test cases written in both Unix and Dos formats. Reference: ANL/RERTR/TM-23 (December 2000). Fortran 77; Unix Sun and PC (Windows 95, 98, NT and Linux) (C00698MNYCP00)

PSR-505/MOSRA-Light

The Department of Nuclear Energy System, Japan Atomic Energy Research Institute, Tokai-mura, Naka-gun, Ibaraki-ken, Japan, through the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed a three-dimensional neutron diffusion calculation code for X-Y-Z geometry. MOSRA-Light can be used in: validation of discontinuity factor for adjoint problem; benchmark on discontinuity factor (forward & adjoint cal.); DVP BWR Benchmark; and void reactivity effect benchmark; etc. MOSRA-Light is based on the 4th order polynomial nodal expansion method (NEM). As the 4th order NEM is not sensitive to mesh sizes, accurate calculation is possible by the use of coarse meshes of about 20 cm. The drastic decrease of number of unknowns in a three-dimensional problem results in very fast computation. Furthermore, it employs newly developed computation algorithm "boundary separated checkerboard sweep method" appropriate to vector computers.

MOSRA-Light was tested by the developers on several computers running Unix and Red Hat Linux 4.2. A Fortran compiler is required on all systems. A C compiler is used to get date, time, and CPU time. As they are not essential for MOSRA-Light calculations, a C compiler is not indispensable. RSICC tested MOSRA-Light on a SUN UltraSparc 60 under SunOS 5.6 with f77 version 5 and C version 5.0 compilers. No executables are provided. The package is transmitted on a DS/HD diskette in a GNU compressed tar file, which includes source, an installer, two test cases, and electronic help files. References: MAN1.TXT and Readme.txt. Fortran-77/Fortran-90; Unix workstations, and Linux PC (P00505MNYWS00).

DLC-209/PWR-AXBUPRO-GKN

Siemens AG Power Generation Group, and Gemeinschaftskraftwerk Neckar GmbH, Germany, through the OECD NEA Data Bank, France, contributed these measured axial burnup profiles. This package contains the following measured PWR axial burnup shapes from NeckarWestheim 1 & 2 (GKN1 and GKN2) in subdirectory PWR-AXBUPRO-GKN12 and benchmarks on the effect of axial burnup shapes in subdirectory PWR-AXBUPRO-GKN2K.

PWR-AXBUPRO-GKN1 (square pitch lattice 15X15 - thermal Power 2497 MW) contains more than 700 EOC axial shapes from cycle 18 up. PWR-AXBUPRO-GKN2 (square pitch lattice 18X18 - thermal Power 3850 MW) contains more than 500 EOC axial shapes from cycle 5 up: more than 170 shapes for an initial fuel enrichment of 3.5 wt.-% 235U, discharge burnup ranges from 16.3 to 44.4 Mwd/kg; more than 170 shapes for an initial fuel enrichment of 3.8 wt.-% 235U, discharge burnup ranges from 14.0 to 52.8 Mwd/kg; and more than 180 shapes for an initial fuel enrichment of 4.0 wt.-% 235U, discharge burnup ranges from 15.5 to 48.9 Mwd/kg.

In PWR-AXBUPRO-GKN2K, the shapes were gathered from cycles 5 through 12 of NPP Neckarwestheim 2. All the shapes refer to EOCs. The shapes are derived from in-core 3D power density distribution measurements based on flux measurements. At 28 fuel assembly positions the flux data are monitored at 32 equidistant axial nodes. Thus, one has a total of 896 measuring points.

The package is transmitted on a CD which includes documentation and a 2MB self-extracting compressed, DOS file. References: Siemens AG Power Generation Group Informal documents (May 26, 1998). ASCII format; IBM PC or other computer (D00209MNYCP00).
 

Obituaries

A. E Profio, 68, ANS member and charter RSICC member, died on February 2, 1999. Ed was a key early contributor to RSICC and the shielding and nuclear data community. Profio received his B.S. in Physics from the Massachusetts Institute of Technology (MIT) in 1953 and became a research scientist at Westinghouse Labs. He served as a Lieutenant in the U.S. Army from 1955 to 1957, working at Ft. Belvoir, Virginia. In 1957, he returned to MIT where he obtained his Ph.D. in nuclear engineering (1963) and took a postdoc for a year. Ed joined the Linac Physics Department at General Atomic in 1964 where he made many important contributions to the shielding and nuclear data communities. He joined the Chemical and Nuclear Engineering Department at the University of California at Santa Barbara (UCSB) in 1969 where he was a stellar professor and researcher. His textbooks: Experimental Reactor Physics and Radiation Shielding and Dosimetry, have played a major role in the nuclear engineering curriculum. Later in his professional life, he turned his attention to medical applications of nuclear methods and successfully developed experimental procedures to detect and treat both lung and breast cancer. Quoting the UCSB Dean of Engineering, "Ed Profio leaves a legacy of accomplishments in his publications and his books, in the students that sat in his class and worked by his side, and the many colleagues that he interacted with and whose lives he touched."

David Trubey, retired RSICC co-founder, writes "I feel a sense of loss even though I have not heard from Ed in a long time. I remember him well for his contributions to the ANS-6 benchmark problems efforts. He always followed through on any commitments. The published benchmark problems in ORNL/RSIC-25 were completed with his help."

Betty Maskewitz, former RSICC director, writes "We regret the passing of long-term friend and RSICC supporter, Edward Profio. He began interaction with RSICC in its earliest years. We always had a special relationship with graduate school students in nuclear science and engineering and continued to follow their professional careers thereafter. Ed, as we called him, discovered RSICC during his graduate and postdoctoral years at MIT. He interacted closely in the following years as a user and as a contributor in radiation transport and shielding information and methods. He was particularly active in nuclear data activities during his years at the GA Linac.

While teaching and doing research at UCSB, he and his graduate students participated in RSICC Seminar Workshops, mainly those in radiation transport and data methodology. Through his papers and textbooks and other research activities, he made important contributions to the nuclear science and engineering knowledge base.

The RSICC staff followed with interest his research in the use of radiation transport and other nuclear methods in medical applications. He was a stalwart in his field. We mourn his passing."

Profio is survived by his wife of 44 years, Janet, a son and two daughters.

John A. Swartout, ANS member since 1955, died October 28, 2000, in Atlanta, GA. He assisted in the development of the chemical separation processes for plutonium for the Manhattan Project; worked for 20 years at the Oak Ridge National Laboratory, including director of the Homogeneous Reactor Project and later became president for Union Carbide.

Paul Hart, ANS member since 1999, associate laboratory director for the National Energy Technology Laboratory in the Dept. of Energy's Office of Environmental Quality and Nuclear Security died December 18, 2000, in Morgantown, WV after a short illness. He previously served as research and development chemist for Union Carbide.

Melvin B. Gottlieb, 83, fusion scientist; served as director of the Princeton Plasma Physics Laboratory in the 1960s and 70s; oversaw construction of the Tokamak Fusion Test Reactor, which began operations in 1982 and went on to produce a record-breaking 11 MV of fusion energy; died December 1, 2000, in Haverford, PA.

Short Courses on Monte Carlo Analysis and Nuclear Criticality Safety

The Department of Nuclear Engineering at the University of Tennessee-Knoxville is offering two short courses for radiation transport and criticality safety specialists during Tennessee Industries Week (TIW-36), August 13-17, 2001.

Monte Carlo Analysis is often the method of choice to solve complex problems in criticality safety 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 specialists 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 five instructors which totals over 120 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 for these courses is July 31, 2001. You may register via the website at http://www.engr.utk.edu/dept/nuclear/TIW.html.

The XIX Autumn School on New Perspectives with Nuclear Radioactivity

Date: October 8-13, 2001

Location: Instituto Superior Tecnico, Lisbon, Portugal

Contact: Inquiries should be addressed to Ms. Sandra Oliveira, (tel +351-21-8419092, fax +351-21-8419143, email NRAD2001@CFIF.IST.UTL.PT).

The aim of the school is to bring together fundamental issues of nuclear radioactivity and nuclear astrophysics as well as some of the technological applications. The indicators show that sciences with a strong social impact will occupy a predominant position in the turn of the century. Nuclear physics is one of the branches of science that is expected to play an important role in this new era. On the other hand, astrophysics has always been an attraction to the human mind. Here, nuclear physics has an essential part. It is thus timely that the nuclear physics community participates actively, either addressing fundamental questions, or applying its knowledge to astrophysics and practical aspects of our society.

There will be a set of invited talks, addressing the most burning issues within the topics of the school, in a format that will allow the participant to get acquainted with some basic ideas, and simultaneously learn about the most recent developments. There will also be some invited seminars and selected short contributions.

A one-page abstract, in LaTex form, is required for the selection of oral contributions. It must be sent by e-mail to NRAD2001@CFIF.IST.UTL.PT. June 1 is the deadline for the submission of abstracts. The final decision will be communicated before June 30. The registration fee is 35 000 PTE. It includes coffee breaks, the welcome reception, the school banquet and a copy of the proceedings. Payment must be done on arrival. The deadline for registration is July 31. More information on the school is available on the web at: http://cfif.ist.utl.pt/~nrad2001.

MCNP™ Workshops

The following is the 2001 schedule for Monte Carlo N-Particle Transport Code Workshop. These classes are taught by the team who develops and maintains MCNP.
5-8 June Introductory Class Los Alamos Natl. Laboratory

The Introductory class is for people who have little or no experience with MCNP. The class surveys the features of MCNP so the beginning user will be exposed to the capabilities of the program, and will have hands-on experience at running the code to solve rudimentary problems. Course topics include Basic Geometry, Source Definitions, Output (Tallies) Specification and Interpretation, Advanced Geometry (repeated structures specification), Variance Reduction Techniques, Statistical Analysis, Criticality, Plotting of Geometry, Tallies, and Particle Tracks, and Neutron/Photon/Electron Physics.

NOTE: While MCNP supports a number of platforms, class computers are usually Unix machines. Experience with Unix will be helpful to the student but is not essential.

Costs For Domestic U.S. Class: Cost for the class is $1,800. There is a $300 discount if payment is received by the close of registration/early payment deadline for each class. Radiation Safety Information Computational Center (RSICC) provides the code and data package and documentation for a reduced fee of $310 to all who complete the class and free to students employed by sponsors that fund RSICC.

The class fee includes a notebook with all class viewgraphs (over 300) and handouts. Dinner the first evening is included as part of your registration fee and snacks and refreshments are provided during class breaks. Lodging will be available for roughly $75 per night. Information will be sent by follow-up letter or email when we receive your registration information.

The class provides interactive computer learning. Time will be available to discuss individual questions and problems with MCNP experts. To register for the LANL class via the Internet, go to http://www.solutionsbyhqc.com/mcnpform.html.

FEE: $1,700 per person (includes the MCNP™ code package). Price subject to change without notice. Payments must be received at least 45 days before class. If payment has not been received by the due date, your space may be given up to the next available person on our waiting list. Refunds are available up to 30 days before the class date. 

PLACE: The Canyon School Complex, Los Alamos National Laboratory, Los Alamos, New Mexico.

Contacts: Inquiries regarding registration and class space availability should be made to David Seagraves, 505-667-4959, fax: 505-665-6071, e-mail: dseagraves@lanl.gov. Technical questions may be directed to Dick Olsher, 505-667-3364, e-mail: dick@lanl.gov. For further information and registration on the Internet, visit: http://drambuie.lanl.gov/~esh4/mcnp.htm.

The Los Alamos MCNP code is a general and powerful Monte Carlo transport code for photons, neutrons, and electrons. MCNP can be safely described as the "industry standard" with more than 600 person-years of development effort behind it. It is supported on a variety of platforms and is now accessible to health physicists, medical physicists, and rad engineers using desktop or laptop personal computers. This 4.5 day course introduces the basic concepts of Monte Carlo, demonstrates how to put together an MCNP input file, and illustrates some health and medical physics applications of the code. No prior knowledge of Monte Carlo is assumed. 

MCNP is ideally suited to the needs of professionals interested in performing radiation shielding and skyshine calculations, detector simulation studies, or dosimetry. 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. Problems that involve a complex geometry can be easily solved using MCNP (e.g., designing a maze entrance to a radiation room). Calculations are based on detailed physics models and very accurate cross section tables that require no energy group compromises to be made. 

A copy of the MCNP code package is included in the price of the course. Your copy of MCNP will be provided directly from the Radiation Safety Information Computational Center (RSICC) at Oak Ridge. Only RSICC is authorized to distribute licensed copies of the MCNP code package. All of the input and output files for the class demonstrations will be provided for self-study on a diskette. The course will focus on providing a practical boost toward learning the program and guiding the student toward useful applications. Extensive practice sessions are scheduled using a personal computer in class. 

The course will be taught by Dick Olsher and David Seagraves of the Health Physics Measurements Group, Los Alamos National Laboratory. Additional staff help will be provided by members of the Health Physics Measurements Group. 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.
