General Atomics’ SiGA-cladded test rods complete irradiation testing in the ATR
General Atomics Electromagnetic Systems (GA-EMS) announced last week that unfueled test rods featuring the company’s SiGA fuel cladding—made of a silicon carbide composite material—successfully survived 120 days of irradiation in the Advanced Test Reactor (ATR) at Idaho National Laboratory.

The interaction of radiation with matter can cause activation or fission reactions producing unstable residuals that decay with the emission of delayed-neutron and/or delayed-gamma radiation. This delayed radiation can be exploited for a variety of purposes, including homeland security, health physics, instrumentation and equipment design, and nuclear forensics. Here we report on capability that has been developed to provide automated simulations of delayed-neutron and/or delayed-gamma radiation using MCNP6. We present new high-fidelity delayed-gamma simulation results for models based on the neutron-fission experiments conducted by Beddingfield and Cecil to illustrate and validate this powerful feature.
