Upgraded safety system of the Ford nuclear reactor

The 1950s-vintage, tube-driven composite safety amplifier system in the Ford nuclear reactor was replaced in the early 1980s by a solid-state system obtained from the Lawrence Livermore Laboratories reactor when it shut down. That system served the reactor until 1994, when it was upgraded with one-for-one replacement modules purchased from General Atomics with funds provided by the U.S. Department of Energy`s research reactor instrumentation upgrade program.
