Sunday April 14 (Session 1; 9:00 a.m. — Noon)

Workshop A:

Radiation Serving Society by Alan Waltar (Texas A&M)

Radiation is ubiquitous in our modern world. It is essentially impossible to go through a day without directly benefiting from radiation in some fashion. Yet the plethora of uses for radiation is only partially understood by our own professionals, and such uses are hardly understood and appreciated at all by the general public.


Dr. Waltar is Past President of the American Nuclear Society and is current President of the Eagle Alliance, a grass-roots organization dedicated to promoting the benefits of radiation in everyday life. He is known for his passion in articulating the myriad uses of radiation in modern society. With an impact of some $500 billion/year in the USA alone (via energy, agriculture, medicine, industry, etc.), it is important for nuclear professionals to better understand how the atom has been able to achieve such prominence today and how it might make even greater humanitarian contributions in the future.

Workshop B:

A Tutorial on the Computer Code SOURCES-4A by Erik Shores (Los Alamos)

The Los Alamos SOURCES code determines neutron production rates and spectra from (alpha,n) reactions, spontaneous fission, and delayed neutron emission due to the decay of radionuclides. Four types of problems are solved: homogeneous media, two-region interface problems, three-region interfaces, and monoenergetic alpha beams incident on a slab. This tutorial will describe the theory behind the code, discuss code applications, and present some example problems. Code documentation will be provided in the form of a 4A manual and pending attendance, a copy of the code, example problems, and relevant documentation will be provided on CD. As there is a special session during the conference on SOURCES applications, this workshop should be a nice introduction for those unfamiliar with the code. For further information, contact Erik Shores (eshores@lanl.gov).


Sunday, April 14, 2002 (Session 2; 1:30 p.m. — 4:30 p.m.)

Workshop C:

Health Physics Aspects of Criticality Safety by Doug Minnema (DOE)

The art and science of Criticality Safety normally focuses on the prevention of a criticality accident; that is, avoiding an inadvertent assembly of a critical system. While prevention is always the key element of criticality safety, radiation protection specialists need to be prepared for responding to an event, should one occur. Therefore, this workshop will focus on developing an understanding of the radiological conditions created during a criticality accident, and estimating the resulting consequences to individuals exposed to the event. The discussions will be based on basic concepts and first principles, and will include some previous accidents as case studies.

Workshop D:

Status and Future Plans For Los Alamos Radiation Transport Modeling by various Los Alamos staff

The current status and future plans for selected Los Alamos Radiation Transport codes and associated nuclear and atomic data bases will be presented by the developers. Specific codes to be discussed include MCNP (Monte Carlo N-Particle) by Larry Cox (Group X-5), MCNPX (eXtensions to MCNP for high energy physics applications) by Laurie Waters (D-10), and the newest deterministic codes PARTISN and ATILLA by Group CCS-4. The latest neutron, photon, and electron library information will be presented by Bob Little (X-5). Vugraph handouts will be provided. The attendees will have the opportunity to discuss their code and data questions with the presenters and other Los Alamos staff during and after the workshop.
