1973 - McMurdo - New Zealand

In 1962 the U.S. Navy install a nuclear power station at McMurdo Sound, in the Ross Sea dependency of Antarctica (administrated by N.Z.) It gives a lot of technical trouble and is finally shut down in 1973. The official U.S. publications state the reasons for the final shutdown as suspected cracks in a coolant pipe and the pressure vessel. (Incidentally, the reactor did not have an Emergency Core Cooling System.) But the Superintendent of N.Z.'s D.S.I.R. Antarctic Research Station, Mr R.B. Thomson, claims that it was shut down for "purely economic reasons".
