Reactor neutron environments can be used to test/screen the sensitivity of unhardened
commercial SRAMs to low-LET neutron-induced upset. Tests indicate both
thermal/epithermal (< 1 keV) and fast neutrons can cause upsets in unhardened parts.
Measured upset rates in reactor environments can be used to estimate the upset rates from
thermal and fast portions of arbitrary neutron spectra.
