CHANGES TO THE COMPUTER CODE COLLECTION

Two changes or additions were made to the computer code collection during the month. One existing code system was updated and one code system was replaced with a newly frozen version.

Argonne National Laboratory, Argonne, Illinois, contributed an update to the VIM code system with the addition of ASCII data libraries and a convenient means to convert them to binary on a target machine. The original distribution included binary sequential data libraries for use with the code system on IBM or Sun workstations. VIM solves the steady-state neutron or photon transport problem in any detailed three-dimensional geometry using either continuous energy-dependent ENDF nuclear data or multigroup cross sections. Neutron transport is carried out in a criticality mode, or in a fixed source mode (optionally incorporating subcritical multiplication). Photon transport is simulated in the fixed source mode. VIM uses standard Monte Carlo methods for particle tracking with several optional variance-reduction techniques.

VIM 3.6 runs on IBM and Sun workstations. At RSICC the system was successfully tested on IBM RS/6000 model 590 under AIX 4.2 with XLF77 version 3.2.2 and on Sun Sparc 20 running SUNOS 5.6 (Solaris 2.6) with f77 version 4.2. The package is transmitted on either a CD or tape cartridge as a compressed tar file which contains installation instructions, the User's Guide, Fortran and C source, and test cases. References: Argonne National Laboratory Report (Unpublished). Fortran 77; Sun, IBM RS/6000 (C00658/MNYWS/01).

Battelle Pacific Northwest National Laboratory, Richland, Washington, contributed a newly frozen version of this visual editor for creating input files for the Los Alamos MCNP4 program. The new MCNP-VISED26f release was upgraded to call slightly modified Fortran subroutines from the initiation and plot modules of MCNP4B. It runs on additional computing platforms and includes numerous bug fixes. Up to 10 dynamic cross section views of the geometry can be utilized to create surfaces and build the geometry. MCNP input files created by VISED can be read by either CCC-200/MCNP4A or CCC-660/MCNP4B.

This menu-driven graphical interface is based on C-language routines that interface with the screen and call Fortran subroutines which initialize the input data and prepare the information for the geometry plots. These Fortran routines in turn call slightly modified Fortran subroutines from the initiation and plot modules of MCNP version 4B. The Fortran subroutines constantly check the evolving input data being received from the C routines and generate the information for dynamically plotting the geometry in user-selected cross-section views. The widgets are created in Motif, and the graphics are created using Xlib routines. VISED runs on HP, SGI, and Sun workstations, or PCs running Red Hat Linux with at least 30 Mbytes of memory. MCNP-VISED will not run on other systems. Fortran and ANSI-C compilers with access to the Xlib and Motif libraries are required to build executables. The package is transmitted on either CD or tape cartridge in a compressed Unix tar file. Reference: unpublished Battelle Pacific Northwest National Laboratory report (October 1997).

SCALE Criticality Safety Training Course--Europe

We have received several requests from SCALE users for organising the next SCALE training course in Europe. As you may know already, from 20-24 September 1999 the "International Conference on Nuclear Criticality Safety (ICNC'99)" will take place in Versailles, France; http://www.ipsn.fr/icnc99/. We have found it therefore convenient to organise this training course the week before that conference. This will facilitate both attendance in the criticality safety training course and be part of the last major event in criticality safety of this decade (sorry but I shall not use the term millennium).

We plan to hold this training course in the premises of the French National Institute for Nuclear Science and Techniques (INSTN) located about 6 miles from Versailles. The course will be given by the authors and code managers from the ORNL (http://www.cad.ornl.gov/scale).

The technical programme of the workshop has been designed by Steve Bowman, SCALE Project Leader, Computational Physics & Engineering Division, Oak Ridge National Laboratory (phone +1 423-574-5263, fax+1 423-576-3513, email st5@ornl.gov. An attendance certificate will be delivered at the end of the course. This course is organised in co-operation with the Radiation Safety Information Computational Center (RSICC). Should you be interested in participating, please return the form by 31 December 1998. More precise information, including the exact participation fee, location, transportation and accommodation possibilities will be provided later.

Reactor Analysis, Radiation Transport, and
Criticality Safety Short Courses

The Department of Nuclear Engineering at the University of Tennessee-Knoxville is offering three five-day short courses of interest to radiation transport specialists during Tennessee Industries Week (TIW-34), August 16-20, 1999.

Computational Methods in Reactor Analysis and Shielding Engineers, scientists, and technical managers who wish to increase their knowledge and understanding of the computational methods and computer codes currently used in nuclear reactor analysis and shielding will be interested in this intensive one-week short course. A good understanding of the neutronic models and associated numerical methods employed in the codes is essential for the successful use of the codes in designing new systems or improving the performance and safety of existing systems.

Areas to be covered include multidimensional diffusion theory methods and perturbation theory methods for applications in reactor statics, space dependent kinetics, and fuel depletion; transport theory methods including the discrete ordinates method, integral transport theory, and the Monte Carlo method; and cross section generation and processing utilizing the AMPX and SCALE systems developed at the oak Ridge National Laboratory.

Special emphasis in the course is placed on the Monte Carlo method because of its widespread use and importance for nuclear system analysis brought about primarily by the increased availability of high performance workstations. The course ends at noon on Friday.

Monte Carlo Analysis is designed specifically for the practicing engineer engaged in shield design and does not presume any prior knowledge of Monte Carlo methods. However, some understanding of radiation transport physics is desirable. A wide range of topics will be presented that will lead to a good understanding of the basics of Monte Carlo analysis and the specialized applications of Monte Carlo methods to practical shielding problems. Many advanced topics will be included that will promote the best use of existing computer code systems. Special attention will be paid to the understanding and Monte Carlo implementation of the adjoint analysis. Advantages and disadvantages of the adjoint mode versus the forward mode of analysis will be described including several practical applications of the adjoint mode of Monte Carlo analysis. Variance reduction techniques will be developed in a comprehensive fashion for both forward and adjoint calculations. The versatile computer code system, MORSE, will be described to illustrate the general features of Monte Carlo computer programs. The relationships of the Monte Carlo methods to other methods of solving radiation transport problems, such as discrete ordinates, will be described, as well as computational advantages and disadvantages of Monte Carlo versus the other methods. This course will cover, in depth, the theory and mathematics a user must have in order to understand and use the Monte Carlo method effectively to solve difficult problems in radiation transport.

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 the 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 course ends at noon on Friday.

The registration fee is $1195 per person for each course. The deadline for registration in these three courses is August 2, 1999.
