Defusing Armageddon: A History of NEST.
Secrecy News from the FAS Project on Government Secrecy

"The mission of NEST is inherently gripping, though its story is not consistently dramatic. It is full of false alarms and potential worst-case scenarios that thankfully never materialize. With the cooperation of some NEST veterans, Richelson provides a painstakingly thorough account, including a previously unpublished list of 103 nuclear extortion threat events from 1970-1993.
"Some of NEST’s exploits were front-page news in their time. I thought I had read (or written) everything worth reading about the 1978 reentry of the Soviet nuclear reactor-powered Cosmos 954 satellite,
which rained radioactive debris over northwest Canada. But Richelson, an exceptionally skilled researcher who is a fellow at the National Security Archive, uncovered some interesting and unfamiliar accounts of that episode, known as Operation Morning Light, in which more than 100 NEST personnel participated."
