GLOBAL THREAT REDUCTION INITIATIVE – REACTOR CONVERSION PROGRAM (GTRI-REACTOR CONVERSION)

The DOE Office of Defense Nuclear Nonproliferation (Office of Global Threat Reduction, NA-21) supports the activities of the Global Threat Reduction Initiative-Reactor Conversion (GTRI-Reactor Conversion) program, previously known as the Reduced Enriched Research and Test Reactor (RERTR) program. The goal of the GTRI-Reactor Conversion program is to minimize and eventually eliminate the use of highly enriched uranium (HEU) in civilian applications. The program achieves its goal by converting research and test reactors to the use of low enriched uranium (LEU) fuels and targets. The program has been very successful, and has developed low-enriched uranium (LEU) fuel materials and designs which can be used effectively in converting the majority of research and test reactors which used HEU to the use of LEU fuel. Current activities focus on development of more advanced, higher density LEU fuels that will allow the conversion of high flux research and test reactors, collaboration with Russian HEU minimization efforts and other international participants in fuel development, development of an LEU-based process to produce Mo-99, and technical assistance to research reactors wishing to convert to LEU.

NE-NATIONAL SECURITY INFORMATION SYSTEMS

The focus of this research area is the development of web based database applications for national security programs for the Department of Energy, National Nuclear Security Administration, and the Department of Defense. Multiple information technology projects are conducted by the section in the security, nuclear nonproliferation and defense areas.

RADIATION DETECTION TECHNOLOGY

Advanced radiation detectors are required for both basic science missions and for applied research in such areas as national security. These activities entail the development of advanced gamma ray and neutron detectors and require physics, engineering or computer programming support in the following areas:
* Development of detector materials for gamma-rays and x-rays,
* fast and thermal neutron detectors for detection of nuclear materials,
* development of algorithms for gamma spectroscopy using heavily degraded spectra,
* electronics design for small detector packages,
* computer simulations of neutron and gamma detector response, and
* development of algorithms for integrated and distributed detector systems.
