NRC Codes Made Available

Four U.S. Nuclear Regulatory Commission (NRC) software packages which were transferred from the Energy Science and Technology Software Center, Oak Ridge, Tennessee, to RSICC were incorporated into the RSICC computer software collection. Please browse the computer abstracts available at RSICC's www site for more information on these packages.






One new package, a foreign contribution, was added to the computer software collection during the month.


The Safety Research Institute, Kalpakkam, Tamilnadu, India, contributed a new package. GUI2QAD is an aid in preparation of input for the QAD-CGPIC program. QAD-CGPIC, which combines CCC-493/QAD-CGGP and PICTURE, is a Fortran code for neutron and gamma-ray shielding calculations by the point kernel method. Provision is available to interactively view the geometry of the system. QAD-CG calculates fast-neutron and gamma-ray penetration through various shield configurations defined by combinatorial geometry specifications. The code QAD-CGPIC is based on the point kernel method and has a provision to select either ANS-6.4.3 1990 GP buildup factor compilation or Capo's buildup factors. The code runs on Pentium-III computers under Windows operating systems. The graphical user interface is coded in Visual Basic 6 and Fortran. The executables were created with a Lahey compiler. It is transmitted on one CD. References: Informal user manual (August 2000) and CCC-493 documentation. Visual Basic 6; Fortran 77; Pentium-III (C00697PC58600).


One new data library, which was a foreign contribution, was added to the collection during the month.


The Japan Atomic Energy Research Institute, Nuclear Data Center, Tokai-mura, Japan, through the OECD NEA Data Bank, Issy-les-Moulineaux, France, contributed the JENDL Dosimetry File 99 (JENDL/D-99), which contains information for 47 nuclides and 67 reactions in the SAND-II group structure and as 0K preprocessed pointwise files. In addition to the present work, the sources of the reactions in this library include: JENDL-3.2, JENDL-2, EAF-99, IRDF-90V2 and others.

For the pointwise data files, the fission and capture cross sections were calculated from the resonance parameters at 0K. For the nuclides with capture and/or fission cross sections, the total cross sections, which were taken from JENDL-3.2, are provided in the pointwise form. The pointwise files include unresolved resonance parameters for self-shielding calculations, but one should not use the resonance parameters to calculate cross sections. Cross sections are given explicitly in the pointwise format (MF=3). The groupwise data were compiled by averaging cross sections in the SAND-II type energy intervals without any energy-dependent weighting function.

The package is transmitted on one CD which contains PDF documentation files and ASCII cross sections written in a self-extracting compressed DOS file. An official report on JENDL/D-99 is being prepared and will be included after it is published. References: Electronic information files (December 1999 and April 2000). ASCII card images; many computers (D00204MNYCP00).

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. The deadline for the submission of abstracts is June 1. 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 for the Year 2001

The following is the 2001 schedule for Monte Carlo N-Particle Transport Code Workshops. These classes are taught by the team who develops and maintains MCNP.
2-6 April Level to be decided Imperial College, London, UK
5-8 June Introductory Class Los Alamos National Laboratory

Introductory classes are for people who have little or no experience with MCNP. The classes survey 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. Classes: 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.

All classes provide interactive computer learning. Time will be available to discuss individual questions and problems with MCNP experts. To register for the LANL classes via the Internet, go to http://www.solutionsbyhqc.com/mcnpform.html. For registration information on the European classes, contact Enrico Sartori, OECD/NEA at sartori@nea.fr.



DATES: May 14-18, 2001 and October 15-19, 2001

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 a 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.

Visual Editor Classes Offered

The Visual Editor is a powerful visualization tool that can be used to rapidly create complex Monte Carlo N Particle (MCNP 4C) geometry models, including lattices, universes, fills, and other geometrical transformations. The Visual Editor can:

Display MCNP 4C geometries in multiple plot windows. 

Create surfaces and cells to build a geometry. 

Create materials using the local xsdir file. 

Store commonly used materials in a material library. 

Sub-divide large cells into smaller cells.

Interactively set cell importances from the plot window. 

Display source points and collision points in the plot window. 

A four-day class is to be held March 19-22, 2001, in Richland, Washington. The class combines teaching on MCNP physics, along with instructions on how to use the Visual Editor. Computer demonstrations and exercises will focus on creating and interrogating input files with the Visual Editor. Demonstrations of advanced visualization work using MCNP will also be made. The class will be taught on Pentium computers running the Linux operating system or Windows NT version if it is working by then. Since the class will provide an overview of MCNP, new users are invited to attend, however, the emphasis of the class will be on the use of the visual editor. Attendees are encouraged to bring their own input files for viewing and modifying in the visual editor. For a more detailed description of the class, lodging, and course fees, please go to: http://www.pnl.gov/eshs/software/ved/class1.html.

A three-day class is to be held October 8-10, 2001, also in Richland. This class will only focus on the use of the visual editor. Users should already be familiar with the use of MCNP. Computer demonstrations and exercises will focus on creating and interrogating input files with the Visual Editor. Demonstrations of advanced visualization work using MCNP will also be made. The class will be taught on Pentium computers running the Linux operating system or Windows NT version if it is working by then. Attendees are encouraged to bring their own input files for viewing and modifying in the visual editor. Further information on this class can be located at: http://www.pnl.gov/eshs/software/ved/class2.html.

If you have any questions concerning these classes, please contact Randy Schwarz at 509-372-4042 or email: randy.schwarz@pnl.gov.

SCALE Training Course Schedule for 2001

The SCALE staff at ORNL will be offering four training courses in 2001. The courses will emphasize hands-on experience solving practical problems on PCs. There will be workgroups of two persons each. No prior experience in the use of SCALE is required to attend. The registration fee is $1800 for one course or $2700 for both spring or fall courses ($300 discount if you register at least one month before the course). A copy of the SCALE software and manual on CD may be obtained directly from RSICC for an additional fee of $310 payable to RSICC. Registrations will be accepted on a first-come basis. Registration forms submitted directly from the Web are preferred. Registration via fax (815-327-6460, yes, the fax area code is different!) or e-mailing Kay Lichtenwalter at lichtenwalsk@ornl.gov is also acceptable. The registration fee must be paid by check, traveler's checks, or credit card (VISA or MasterCard only).

Class size is limited and courses are subject to cancellation if minimum enrollment is not obtained one month prior to the course. Course fees are refundable up to one month before each class. Classes are cosponsored by RSICC. Foreign nationals must register at least six weeks in advance. For further information, contact Kay at 865-574-9213 or visit the web, http://www.cped.ornl.gov/scale/ trcourse.html.

SCALE Shielding and Source Terms Course (April 23-27, 2001) and (October 15-19, 2001)

The SCALE Shielding and Source Terms Course emphasizes SAS2 and ORIGEN-ARP (depletion/source-term generation) and SAS3 and SAS4 using MORSE-SGC (3-D Monte Carlo neutron/gamma shielding). It also covers SAS1/XSDRNPM (1-D neutron/gamma shielding) and QADS/QAD-CGGP (3-D point kernel gamma shielding). 

SCALE KENO-VI Criticality Course (April 30-May 4, 2001)

The SCALE KENO VI Criticality Course focuses on KENO VI and the associated criticality analysis sequences in CSAS6. KENO VI is the latest version of the KENO Monte Carlo criticality safety code. KENO VI contains a much larger set of geometrical bodies than KENO V.a, including cuboids, cylinders, spheres, cones, dodecahedrons, elliptical cylinders, ellipsoids, hoppers, parallelpipeds, planes, rhomboids, and wedges. The flexibility of KENO VI is increased by allowing the following features: intersecting geometry regions; hexagonal as well as cuboidal arrays; regions, holes, arrays, and units rotated to any angle and truncated to any position; and the use of an array boundary that intersects the array. Users should be aware that the added geometry features in KENO VI can result in significantly longer run times than KENO V.a. A KENO VI problem that can be modeled in KENO V.a will typically run four times as long in KENO VI as in KENO V.a. Thus the new version VI is not a replacement for the existing version V.a, but an additional version for more complex geometries that could not be modeled previously. Two-dimensional color plots of the geometry model can be generated in KENO V.a, or the model may be viewed using the KENO3D 3-D visualization tool. 

SCALE KENO-Va Criticality Course (October 22-26, 2001) 

The SCALE KENO V.a Criticality Course focuses on KENO V.a and the associated criticality analysis sequences in CSAS. KENO V.a is a widely used 3-D multigroup Monte Carlo criticality safety analysis code that has been in use for approximately 15 years. KENO V.a is a fast, easy-to-use code that allows users to build complex geometry models using basic geometrical bodies of cuboids, spheres, cylinders, hemispheres, and hemicylinders. Two-dimensional color plots of the geometry model can be generated.
