The first newsletter I produced was typed on an IBM Mag Card (there are children at IBM who do not know what a Mag Card is) and it was the first RSIC Newsletter produced with the Aps µ5 phototypesetter. It somehow got published with the most patient help from Bill Griffith who wrote and modified the software I needed to get the result I wanted and David K. Trubey who helped me interpret it. That was issue 205 and the last issue I published was 422.

Los Alamos National Laboratory, Los Alamos, New Mexico, and Texas A&M University, llege Station, Texas, contributed a newly frozen version of this code system to determine a,n; spontaneous-fission; and b,n delayed neutron sources and spectra due to the decay of radionuclides. The previous version, SOURCES 3A, calculated a,n source rate and spectra for three problem types: homogeneous medium, interface and alpha beam problems. The new version, SOURCES-4A, will also calculate a,n source rate and spectra in a thin neutron-producing region between two alpha-producing regions. Spontaneous-fission spectra are calculated with evaluated half-life, spontaneous-fission branching and Watt spectrum parameters for 43 actinides. The (a,n) spectra are calculated using an assumed isotropic neutron angular distribution in the center-of-mass system with a library of 89 nuclide decay alpha spectra, 24 sets of measured and/or evaluated (a,n) cross sections and product nuclide level branching fractions, and functional alpha-particle stopping cross sections for Z < 106.

SOURCES-4A runs on many computers including Sun, IBM RS/6000 and personal computers. At RSICC the code was tested on Sun SparcStation and on IBM RS/6000 using Fortran 77 compilers. A Lahey F77/L3-EM32 v5.2 compiled executable for PC users is included in the package; all other computers require a Fortran compiler. The package is transmitted in both DOS and Unix compressed formats on a CD which includes the electronic (PDF) document, Fortran source, PC executable, data libraries, and test cases in both DOS and tar formats. References: LA-13639-MS (September 1999). Fortran 77; Sun and PC (C00661MNYCP01).
 

Synthesis Srl, Milano, Italy, and ENEL SpA, Milano, Italy, through the OECD Nuclear Energy Agency Data Bank, Issy-Les Molineaux, France, contributed this code system for 2-group, 3D neutronic kinetics calculations coupled to core thermal hydraulics. QUARK is a combined computer program comprising a revised version of the QUANDRY three-dimensional, two-group neutron kinetics code and an upgraded version of the COBRA transient core analysis code (COBRA-EN). Starting from either a critical steady-state (k-effective or critical dilute boron problem) or a subcritical steady-state (fixed source problem) in a PWR plant, the code allows one to simulate the neutronic and thermal-hydraulic core transient response to reactivity accidents initiated both inside the vessel (such as a control rod ejection) and outside the vessel (such as the sudden change of the boron concentration in the coolant).

QUARK runs under DOS or WINDOWS, and the included executable was created with MS FORTRAN Power Station Compiler Version 1.0 and tested at RSICC in a DOS window of Windows95. The package is transmitted on CD and includes the referenced document in electronic PDF format and a compressed, self-extracting DOS file which contains the source, executable, test cases and data files. Reference: Synthesis Srl Rep. 1034/1 (September 1994). Fortran 77; PC (P00492PC58600).
 

"Did you know or remember Bob Coveyou? He was quite a character. In the 1950s or early 1960s, I was looking in the back of the Methodist hymnal, which had the church calendar for many years in advance. I noticed that in the year 2000, Easter fell on my birthday. Not long afterward, I remarked to Coveyou that Easter fell on my birthday in the year 2000. He replied that that was the most useless information that he had ever been given! I never forgot the exchange. He died a couple of years ago, so I never had a chance to remind him.

He originally came to Oak Ridge as a health physicist. I knew him as a great Monte Carlo expert. He did quite a lot of original research on random numbers and was the original leader for the development of O5R. I remember one time when a senior member of our Division came into his office which also held Bill Kinney and Gerald (Jerry) Sullivan, and later David Irving and Betty Maskewitz, and asked Coveyou what he was doing. Bob spent much time writing equations on a big pad of paper. He told the visitor, "You would not understand if I told you." Blizard, our Division Director, called Coveyou and his protégées his "Baker Street Irregulars" after the street urchins that kept Sherlock Holmes informed. Becky Rickman, Blizard's secretary, said Blizard took pride in hiring eccentric people and getting good work from them.

Originally O5R was called ORRRRR, i.e., Oak Ridge Research Random Reactor Routine. There was a precedent for this, the Oak Ridge Research Reactor, known as the ORR. I believe it was Lorraine Abbott who substituted the more civilized term, "O5R" in the first publication. The term was a problem for information retrievers because it became "05R" in secondary publications such as Nuclear Science Abstracts. An important innovation in O5R, to utilize memory efficiently on the 32K-word IBM 7090, was to break up the calculation into energy bands so only a small fraction of the cross sections would be in memory at one time."
 

Paul Rudolph Jolles, 80, Swiss diplomat; served in 1957 as executive secretary of the commission that planned the International Atomic Energy Agency, and was subsequently named an IAEA deputy director general, a capacity in which he served until 1961; died on March 11 in Bern, Switzerland.

FEE: $1,700 per person (includes the MCNP™ code package)

PLACE: The Canyon School Complex, Los Alamos National Laboratory

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. Extensive interactive practice sessions are conducted on a personal computer. Topics will include overview of the MCNP™ code and the Monte Carlo method, basic concepts, 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.

The course fee includes a complete MCNP™ code package, distributed directly from the Radiation Safety Information Computational Center (RSICC). Students will also 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. The course is offered by the Health Physics Measurements Group at the Los Alamos National Laboratory and is co-sponsored by RSICC.

Registration is available online at http://drambuie.lanl.gov/~esh4/mcnp.htm; however, to guarantee a space payment must be received prior to the registration deadline. Make checks payable to the University of California (checks must be in U.S. dollars on a U.S. bank) and mail together with name, address, and phone number to the address above.

October 9-12 in Richland, Washington. Cost $1400

The source code package can be obtained directly from RSICC.

The class will combine 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. Attendees are encouraged to bring their own input files for viewing and modifying in the visual editor. It is recommended that you have experience with MCNP before taking this class. For additional information contact Randy Schwarz, MS K8-34, P. O. Box 999, Richland, WA 99352 (509-372-4042, fax 509-372-6421, email randy.schwarz@pnl.gov, url http://www.pnl.gov/eshs/software/ved.html).
 

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.

Advanced classes are for people with MCNP experience who want to extend their knowledge and understanding. Most areas of MCNP operation will be discussed in detail, with emphasis on advanced geometry, advanced variance reduction techniques, perturbation enhancement & cumulative tallies. Time will be available to discuss approaches to specific problems of interest to students.

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.

Year 2000 classes will showcase the latest release of MCNP, Version 4C. Major new features that will be discussed include:

• Macrobodies
• Unresolved Resonance Treatment
• Perturbation Enhancement
• Alpha Eigenvalues
• Cumulative Tallies
