ANS Welcomes Abraham's Endorsement of Yucca Mountain

LA GRANGE PARK, IL, January 10, 2002--Energy Secretary Spencer Abraham's endorsement of Yucca Mountain as a suitable repository for spent nuclear fuel and high-level nuclear waste is a giant step toward solving one of the most controversial issues involving nuclear energy, says the American Nuclear Society.

"We have high confidence that Yucca Mountain is a suitable site, and we applaud the Department of Energy's recommendation to proceed with the next stage of repository development, the application of a license for repository construction," said ANS Vice President/President-Elect Harold B. Ray. "The pre-closure and post-closure assessments of Yucca Mountain convince us that the combination of site and design features provide public health protection with a considerable margin of safety."

Following the adoption of the Nuclear Waste Policy Act of 1982, DOE was directed to find a site for disposing of highly radioactive materials. Many scientists have concluded that storing such material deep underground is the safest method.

The Yucca Mountain site, located about 90 miles northwest of Las Vegas, NV., is situated in a mountain range with a unique combination of rock characteristics and an extremely deep water table (800 to 1,000 feet below the level of the repository). It has undergone years of study by scientists, engineers and other nuclear experts. One such study was the Yucca Mountain Preliminary Site Suitability Evaluation (PSSE), which incorporated the most recent data from field and laboratory experiments, and examined many alternative models that have never before been explored.

Work performed by the DOE, national laboratories and other government agencies such as the U.S. Geological Survey and the Environmental Protection Agency provided an impressive comprehensive collection of interdisciplinary studies and reports. These studies concluded that the Yucca Mountain site is well suited to become the nation's first geological repository.

"We're confident that the DOE has selected and characterized a site that, with appropriate engineering design and operation, can meet with high confidence the regulatory standard for public health and safety," said Ray. "The PSSE shows that the site can meet the post-closure standard, and the analyses indicate that pre-closure health and safety protection are more than adequate."

ANS' confidence on the Yucca Mountain site is based on several factors, including:

--The project has demonstrated that the natural features of Yucca Mountain contribute very significantly to public health protection;

--The project has adopted a highly robust engineered barrier system employing multiple, independent barriers to provide long-term confinement of radionuclides; and

--DOE and the Nuclear Regulatory Commission will continue to conduct additional research and monitoring activities over the next several decades to further bolster confidence in the safety of the repository.

"We applaud the DOE for conducting such a credible interdisciplinary analysis demonstrating suitability of the Yucca Mountain site for this nation's high-level geological repository, and we are prepared to contribute to the next step of Yucca Mountain," said Ray. "It's clear the time has come for the administration to prepare a license application to the NRC for permission to construct and operate Yucca Mountain. This is an important step for the future of nuclear energy."

ANS News Release
Marston Responds to San Jose Newspaper

Dr. Theodore U. Marston, Vice President and Chief Nuclear Officer of EPRI located in Palo Alto, CA, wrote Brandon Bailey in response to his article "U.S. Favors Plan to Store Nuclear Waste in Nevada" published January 11, 2002, in the San Jose Mercury News.

Dear Mr. Bailey:

I would like to congratulate you on your well-balanced article on the Nuclear Waste Repository proposal. This is a very controversial topic and the public requires objective reporting so they can develop their own opinions on the subject. One fact that was not included in your article is that the proposed repository is located on the southwest boundary of the Nevada Test Site. Within a distance of 25 to 30 miles from Yucca Mountain most of the 828 underground nuclear tests were conducted. A number of the weapons tests were conducted deep in the ground at or near the water table. It is not feasible to remediate the Nevada Test Site. In contrast, the repository is located about a thousand feet above the water table.

I believe the public has the perception that Yucca Mountain is located in a pristine desert area, rather than in close proximity to where we have already impacted the ground with our nation's nuclear testing program. The addition of the used nuclear fuel in this region will have infinitesimal effect on the habitability of this area for future generations.

Thank you for your time and attention.
Very truly yours,

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 code collection. Please browse the computer code abstracts available at RSICC's www site for more information on these packages.


PSR-437/ORSMAC (U.S. distribution only)


PSR-440/FEP 4.16

Changes to the Computer Code and Data Collection

A new package and a newly frozen package were added to the computer code software and data collection.

CCC-704/SlideRule 1.0
OP SYS: Windows
Language: C++
Computers: Pentium
Format: WinZip

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed this rapid PC-based tool for estimating pertinent information needed to guide response team activities and help characterize some types of nuclear criticality accidents. The concept uses a series of sliding graphs that function similarly to a slide rule. This tool was developed with the promise that visual demonstration of trends (e.g., dose versus time or distance) are helpful to response personnel. The SlideRule provides rapid assessments for direct radiation approximations and is useful for solving for parameters that are dependent upon independent specific parameters such as variable shielding, distances, and anticipated time related radiation doses to personnel. The SlideRule is designed to provide estimates of the following:

  • magnitude of the fission yield based on personnel or field radiation measurements,
  • neutron- and gamma-dose at variable unshielded distances from the accident,
  • the skyshine component of the dose,
  • time-integrated radiation dose estimates at variable times/distances from the accident,
  • 1-minute gamma radiation dose integrals at variable times/distances from the accident, and
  • dose-reduction factors for variable thicknesses of steel, concrete, and water.
The SlideRule estimates unknown data based on data available to emergency response personnel, including:
  • exposure information about "accident victims,"
  • estimates of potential exposures to emergency response re-entry personnel,
  • estimation of future radiation field magnitudes, and
  • fission yield estimates.
The SlideRule provides estimates for five unreflected spherical systems that provide general characteristics of operations likely in facilities licensed by the NRC:
  • low-enriched (5 wt % 235U) uranyl fluoride;
  • damp, low-enriched (5 wt % 235U) UO2;
  • high-enriched (93 wt % 235U) uranyl nitrate solution;
  • high-enriched (93 wt % 235U) uranium metal; and
  • damp, high-enriched (93 wt % 235U).
The code runs interactively and nearly instantaneous response time. SlideRule runs on Windows 95/NT or later personal computers with a minimum of 32 MB RAM. Nominal hard disk requirements are less than 10 MB. The included SlideRule executable was created using Microsoft Visual C++ and runs under Windows 95/NT or later. Source files are not distributed. The package is transmitted on a CD which includes the SlideRule executable and online help in a self-extracting WinZIP file.

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed a newly frozen version of this code system for multilevel R-matrix fits to neutron and charged-particle cross-section data using Bayes' equations. SAMMY-M6-Beta, release December 2001, differs from previous versions (M5) primarily in that charged particles can be used for both incident and exit channels. The earlier release (M5) did not properly treat incident charged particles, although charged-particle final states were properly treated. SAMMY can now be used to analyze, for example, (n,alpha) or (alpha,n) reactions in addition to previously available options: transmission, elastic (both angle-integrated and differential), fission, inelastic, capture, and absorption cross sections, eta, self-indication, and certain types of integral data. Angle-differential reaction cross sections can also be treated in M6-beta.

Users should be aware that Version M6-Beta is essentially a pre-release of version M6. In order to make the incident-charged-particle version available as soon as possible, no attempt has been made to complete the update of the documentation (users' manual). Though "old" features of the code, and the new incident-charged-particle capability, have been thoroughly tested prior to this release, implementation is in preliminary stages.

The included PC executables were created on a Dell Dimension 4100 operating under Windows 2000 with Compaq Visual Fortran Professional Edition 6.5. All Unix systems require a Fortran compiler to create executables. SAMMY-M6-Beta was tested at RSICC on the following machines:

IBM RS/6000 Model 270 AIX 4.3.3 with XLF 7.1 and XLC 4.4
SUN UltraSparc 60 Solaris 2.6 using f77 V 5.0 or f90
HP B1000 under HP-UX B.10.20 using f77 10.2
DEC/Alpha 500au under Digial Unix 4.0D with Fortran 77 5.1-8
Micron P3 running Windows 2000 using included executables.

The package is transmitted on a CD with both Unix and Windows distribution files. The Unix tar file contains source codes, scripts, tutorials, and test cases for Unix and Linux users. The self-extracting compressed Windows file contains source codes, executables, batch files, and test cases for Windows PC users. Reference: ORNL/TM-9179/R5 (October 2000). Fortran; DEC Alpha (Unix and VMS), IBM RS/6000, SUN, HP, PC (P00158/IRISC/07).


The proposed courses, tutorials, etc. will be held depending on user interest and participation. For more information or support of this workshop please contact hatmakerna@ornl.gov or sartori@nea.fr.

Workshop/Tutorial (tentative) on AMPX-2000, the latest version of the AMPX cross-section processing system that is developed and maintained by the Oak Ridge National Laboratory (ORNL). AMPX-2000 processes nuclear data evaluations that conform to the Evaluated Nuclear Data File (ENDF/B) format specifications. AMPX-2000 has the capability to process ENDF/B formats through Version VI and generate continuous-energy or multigroup cross-section libraries for neutron and/or photon transport. The objective of the workshop is to introduce new and experienced users to AMPX-2000. The workshop consists of classroom instruction provided by the AMPX code developers with an emphasis on use of the code system to process nuclear data evaluations. The workshop will also provide the participants with the opportunity to use AMPX to process nuclear data evaluations. Upon completion of the workshop, participants will have an understanding of the code system and be able to use AMPX to process ENDF/B evaluations and generate cross-section data for use in radiation transport codes. The proposed Agenda for a 5-day Workshop/Tutorial follows:

Day 1 - The first day will provide an introduction to ENDF/B formats and concepts associated with cross-section data. Followed by an overview of the AMPX-2000 code system that will include a discussion of the modular design philosophy and special features associated with the code system. The history of its sponsorship, major releases, etc., will be covered. In addition, a comprehensive overview of the processing capabilities will be provided. Differences and similarities to the NJOY processing system will be reviewed as appropriate. The remaining part of the first day will be devoted to a description of the AMPX modules and procedures that are used to generate continuous-energy cross sections from ENDF/B evaluations. In addition, the AMPX modules and procedures for processing the ENDF/B collision kinematics data will be described in detail.

Day 2 - Classroom instruction for the second day will focus on the modules and procedures that are used to produce multigroup neutron and photon cross-section libraries. The morning session will emphasize the AMPX modules that relate to producing multigroup data (e.g., generating weighting spectra, resonance-parameter processing, thermal-data processing, etc.). Workshop participants will gain familiarity with the different types of data that are used to provide a multigroup dataset for transport calculations. The afternoon session will be devoted to "hands-on" exercises that emphasize the course material from the first two days of instruction. Participants will have the opportunity to prepare input for producing continuous-energy and multigroup data using AMPX-2000.

Day 3 - The third day will begin with a review of the classroom exercises from Day Two followed by additional discussions on multigroup library processing as needed. New AMPX capabilities for generating probability tables and covariance matrices will be discussed in the morning session. The afternoon session will be devoted to additional classroom exercises related to generating continuous-energy and multigroup data. In addition, workshop participants will have the opportunity to generate probability tables and process ENDF/B uncertainty data with AMPX-2000.

Day 4 - The fourth day will begin with a review of the sample problems of the preceding afternoon session followed by classroom instruction for the various resonance self-shielding treatments that are provided in the AMPX system. The material will build upon the information presented on Day Two and include discussions of modules and procedures that must be used to prepare the appropriate data to be used in the treatments. The afternoon session will provide classroom exercises that make use of the course material presented in the morning session.

Day 5 - The fifth day will provide a review of the problems investigated on Day Four. A discussion of various AMPX-2000 utility modules will be provided. AMPX-2000 produces data in a wide variety of formats and has the capability to interface with the NJOY code system. The material covered on Day Five will focus on the utility modules that are needed to perform specialized data manipulation tasks (e.g., convert data between NJOY and AMPX, compare data libraries, constructing and maintaining a special energy boundary library for group structures, procedures for constructing specialized 1/ES t functions, AMPX installation procedures for different computer platforms, etc).

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, 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.

All 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. Followup consultation for class participants will be provided.

Classes are taught directly by experienced MCNPX code developers and instructors. For more information on code versions and their capabilities, go to the MCNPX Workshops web site http://mcnpxworkshops.com.
