The phrase ‘the peaceful use of nuclear weapons’ might sound like the ultimate oxymoron. Building a nuclear stockpile meant more than just building reactors; nuclear weapons designs still had to be constructed, tested, and refined. Indeed, the idea of using nuclear weapons for nonmilitary purposes is as old as nuclear weapons themselves. Scientists concluded that nuclear weapons were unsuited to digging canals, and the Pechora-Kama project itself was abandoned in 1986. Yet despite its similarities to the American project, Nuclear Explosions for the National Economy holds the distinction of carrying out the only truly practical peaceful nuclear explosions in history.
