Mission Radiation Environment Modeling and Analysis: Avionics Trade Study for GCD Rad-Neuro Project
The two main objectives of this trade study are characterizing the mission radiation environment for multiple Design Reference Missions (DRM) and analysis of radiation effects on avionics with the goal of producing radiation tolerant Neuromorphic Computing processor chips with innovative radiation-induced fault mitigation. The NASA process for defining radiation requirements for flight avionics is applied to this domain. The effects of trapped protons and electrons in the Van Allen radiation belts predominates in Low-Earth-Orbit (LEO) and the solar wind, solar flares and Galactic Cosmic Rays (GCRs) are the dominant radiation challenge in the open space between the planets of our solar system. The nature and energy of the particles that cause circuit upset and failure is very different in the two regimes. Two results are produced from the radiation models: determining the Total Integrated Dose (TID) experienced by avionics for a given DRM and predicting the Single Event Effects (SEE) rates for avionics during high rate exposure. These tools are applied to existing semiconductors and can be used for predicting the radiation performance of future semiconductors based on early radiation testing of new devices.

Implications of DOE O 1027 Guidance on Rad-NESHAP Programs
This presentation is for the national Radionuclide NESHAP meeting, an embedded topic of the 2012 Health Physics Society Annual Meeting in Sacramento, CA. The Radionuclide NESHAP program is responsible for measuring and reporting the amount of airborne radioactive material released from DOE facilities. The issue at hand is recent guidance put forth by the Department of Energy regarding threshold limits for Category 3 and Category 2 nuclear facilities. Updates to calculation methods have resulted in increased amounts of radioactive material allowed in inventory for facilities before they reach levels which require them to be categorized as a Category 2 or 3 nuclear facility. With larger radioactive material inventories, there may be a corresponding increase in overall facility emissions. This can have permitting and monitoring impacts for DOE sites, as well as political ramifications with citizen organizations. This presentation is intended to raise awareness of the new guidance and associated issues, and to stimulate discussion among DOE Radionuclide NESHAP representatives.
