Seldon Keith Penny, a Founder and First RSIC Director, Died March 17, 2005

Seldon Keith Penny came to the Oak Ridge National Laboratory’s Neutron Physics Division in 1955 from Oklahoma where he had received a degree in Engineering Physics from Oklahoma University. He later attended the University of Tennessee and obtained a doctorate degree in Physics. He attended ORNL/ORSORT (Oak Ridge School of Reactor Technology) and became involved in shielding activities. He, with David Trubey and Betty F. Maskewitz, was selected to initiate a prototype ‘information analysis center,’ to preserve the information and technology generated in the Aircraft Nuclear Propulsion and related programs of the 1950s and 1960s.

The Radiation Shielding Information Center (RSIC) was established in 1962 with Penny as the first director. He and Trubey, with Peggy Emmett as programmer, developed SARIS (Storage & Retrieval Information System), the first of its kind as a repository of the published literature, in this case, in radiation transport and shielding.

Penny led RSIC in the formative years (1962–1966) with enthusiasm as the staff and volunteer coordinators within the user community worked cooperatively to build the RSIC base of selected literature, computer codes, and nuclear data. The seminar-workshop, as a device to disseminate a large body of information to an interested group of researchers, was initiated at ORNL in late 1965 under his leadership. The seminar featured Monte Carlo techniques and the computer code system, Oak Ridge Random Research Reactor System (O5R), was selected for the workshop.

The success of the seminar-workshop led to an invitation from the OECD Nuclear Energy Agency (NEA) Computer Programme Library, located at EURATOM, Ispra, Italy, to repeat the activity with the cooperating European shielding research community. Following the seminar-workshop (April 25–29, 1966), Penny and Maskewitz made RSIC orientation visits to nuclear research institutions in Italy, West Germany, France, Sweden, Denmark, the Netherlands, and the United Kingdom.  A cooperative Agreement for Exchange, initiated in the early years, has continued between OECD/NEA Data Bank and DOE/ORNL RSICC.

Penny left RSIC in mid-year 1966 for an assignment with Union Carbide, NY.  He returned to ORNL in March 1970 to work on various research programs, the last in the Computer Sciences. He retired in 1989 after 35 years of service.

Penny is survived by his wife Marvene, four children, twelve grandchildren, and one great granddaughter.

In memory of Lev Vasilievich Mayorov

Enrico Sartori has sent us the sad news that Dr. Lev Vasilievich Mayorov from the RRC “Kurchatov Institut” passed away on 15 February 2005. During his career Dr. Mayorov published more than 150 scientific papers on reactor physics, radiative transfer, and the Monte Carlo method. “All of us, who have met him and who have listened to his profound knowledge and wisdom and have enjoyed his cheerful company will miss him very much.”

Jose Reyes Jr. named ‘Role Model of the Week’

Our friend David W. DePaoli has alerted RSICC to a story in The Daily Barometer Online about an engineer inspired by Oak Ridge National Laboratory. Jose Reyes Jr. was honored by HENAAC, a national organization that promotes Hispanics in engineering, science, mathematics and technology, as “Role Model of the Week,” for his research in the Oregon State University Advanced Plant Experiment Reactor Facility and for including student assistants in his research. Reyes is a professor and interim head of the Oregon State University Department of Nuclear Engineering and Radiation Health Physics. His exploration of nuclear energy began when his father gave him a book about Oak Ridge National Laboratory. Reyes recently returned from a one-year project with the United Nations at the International Atomic Energy Agency. He helped establish an agreement between 14 countries, which have embarked on a four-year plan to enable member states to improve the “reliability, economics and safety” of reactors.

MCNPX is the LANL all-particle, all-energy (eV-TeV) Monte Carlo transport code based on MCNP4C, LAHET, CEM, etc. MCNPX has been in active development since 1995 and is sponsored by the particle accelerator community. It has now become an accepted tool for a broad range of applications by nuclear engineers, physicists, and scientists. The MCNPX development effort has expanded the use of the Los Alamos tools to applications such as APT, waste transmutation, accelerator shielding and health physics, particle beam cancer therapy, space shielding and cosmic ray analysis, single event effects in semiconductors, radiography, and more detailed analysis of the effects of light and heavy ions in matter. In addition, the entire functionality of MCNP4C is retained. New variance reduction and data analysis techniques, many adapted from high-energy accelerator methodologies, have also been added, such as the extensive “mesh tally” capability which allows up to 3-d plotting of particle tracks, fluence and fluence-derived quantities, energy deposition, next event estimator generation contributions and particle sources.

The workshops include hands-on instruction, generally on PC Windows machines. Subject to participant export approval for the MCNPX beta test team, participants will be able to access the Fortran-90 version of MCNPX 2.4, the LA150 (150 MeV) cross-section data for over 40 isotopes for incident neutrons and protons and 12 for photonuclear interactions, and a notebook of viewgraphs.

Follow-up consultation for class participants will be provided.

The classes are taught by experienced MCNPX code developers and instructors. More information on code versions and capabilities is available at MCNPX Workshops web site http://mcnpxworkshops.com.
