Irradiation Test Results on Cryogenics Electronic Cards using the Smartfusion2 FPGA

For direct cycle gas cooled high temperature reactor designs, operating conditions may be limited as a result of excessive maintenance dose rates caused by the Ag-110m source term on the turbine. It is therefore important to accurately predict silver release from fuel during reactor operation. Traditionally diffusion models were used to derive transport parameters from limited irradiation testing of fuel materials and components. Best estimates for all applicable German fuel irradiation tests with defendable uncertainty ranges were never derived. However, diffusion theory and current parameters cannot account for all irradiation and heat-up test results, and for some tests, it appears unacceptably conservative. Other transport mechanisms have been suggested, and alternative calculation models are being considered. In this paper the applicable German irradiation test results are evaluated with a classic diffusion model as well as an alternative model called the Molecular Vapour transport Release (MVR) model. New transport models and parameters for silver in fuel materials are suggested and compared.

Irradiation Test

Antifuse FPGA because for its low power consumption, high reliability, high security, etc., are widely used in space electronic systems. However, antifuse FPGA running in the space environment is also vulnerable to space radiation. This paper analyzes the single event effects in antifuse FPGA in detail and put forward the TMR and EDAC anti-SEE hardening design and implementation methods. The ground heavy ions accelerated test is conducted to verify the design of hardening; test results and analysis show that the hardening design method can effectively improve the COTS antifuse FPGA for space applications reliability.
