92. 1970 - WINDSCALE. U.K.

Criticality accident. Uncontrolled release of radiation caused by neglect of an accumulation of plutonium in a vessel. Engineers did not know there was any plutonium residue in the vessel as the reactor did not feature the necessary neutron monitoring devices. (Sources: C. Wakstein, P.212)

93. 1970 - BENZNAU, C.S.R.

10 workers exposed to radioactivity. (Sources: Work Circle Environmental Protection)

A nuclear generating device containing plutonium crashed from the Apollo 13 moonshot in the sea near Norfolk Island. Records Show that it contained 3.78 kgs of plutonium 238 N.A.S.A. does not know the location of the module component and there has been no attempt to locate or recover it. Information about the plutonium content was withheld until July, 1980. Mr. Bill Wood, spokesperson in Australia for the U.S. National and Aeronautics and Space Administration, strongly denied there was any danger from the plutonium. Mr. Hesphy, Head of Citizens for Space Demilitarization, said the plutonium involved was very active and would remain so for many years. Although plutonium 238 could not penetrate the human akin, it is highly toxic and could be absorbed by fish and upset the delicately balanced ecosystem of the sea. ("The Australian" - 31st July, 1980)

97. 1970, 5th June - INDIAN POINT, NY, U.S.A.

At the Symposium of the International Atomic energy Agency it was revealed that reprocessing plants "lost" through liquid and solid discharges 1.5% of the materials they process. It was also stated that a nuclear power plant diffuses 30 curies of radioactivity per megawatt per year into the atmosphere. (Thieberger p.5)

101. 1970 - WINDSCALE, U.K.

Uncontrolled radiation release follows failure to observe safety procedures. Negligence blamed as plutonium accumulated in vessel. (Wakestein - "The Myth of Nuclear Safety" -The Ecologist - July, 1977)

102. 1970, 30th September - HANFORD, WA, U.S.A.

A loss of coolant automatically started the primary SCRAM system (SCRAM is the rapid reinsertion of control rods). The system failed due to a short circuit. The backup SCRAM system worked. General Electric calculated that the probability of a failure in SCRAM was one in ten billion; the actual rate so far has been one in ten thousand. Past accidents at Hanford occurred on 3rd October, 1954, 4th January 1955, and 6th January 1966. (Jean Geue A.A.E.C; Webb, R.E. p.192-193)

105. 1971, January - CHARLEUOIX, MICHIGAN, U.S.A.

A B-52 bomber crashed at Lake Michigan, 2 miles from a small B.W.R. reactor An eyewitness said the plane was heading directly in line with the reactor when it crashed, raining a fireball 200-600 ft in the air. "If the plane had crashed into the reactor there would have been a mayor public disaster... "It has been speculated by the Grumman aerospace official that the plane may have flown into radioactive gasses normally discharged by the reactor's effluent stack. The radioactivity could have interfered with the plane's electronic guidance systems. No report has been made to the public. (R.E. Webb, 1 p.194-145)

Five hundred gallons of radioactive primary coolant was inadvertently discharged into Thames River, near New London, Connecticut, from a nuclear powered submarine. (Melbourne "Sun"- 8th Oct 1976, p.23).


Shippport received gamma ray does from Duguesne reactor 56% of permitted annual dose. (Nucleus, 26th July 1979, p.16)


The Millstone B.W.R. reactor suffered a malfunction of the steam valve which caused the radioactivity and hence the power level to rise beyond the fuel or rated power level. The SCRAM system or reactor safety system went into action but had it failed there would have been a rapid core melting, a nuclear runaway explosion, and finally a major public disaster. There is no back up safety system for SCRAM supposedly because SCRAM contains several back up electrical switches. However, all these switches were manufactured improperly causing the coating to become sticky over time. This means that the switches would not be able to open in an emergency. The failure of the back up electrical switches will increase with the passage of time.

The A.E.C. in 1973 issued a regulation requiring back up systems for SCRAM for reactors whose licenses were submitted after 1977. However, this leaves 200 reactors without back up safety systems. (Webb, p.193-194)

112. 1971, mid-year - CLINTON, TENNESSEE, U.S.A.

The manufacturer of sealed radioactive sources abandoned a plant site leaving a significantly contaminated area. The cost of decontamination fell, by default, on the Federal and State Governments. ("A Landscape of Nuclear Tombs", Alexic Parks).

There were two gates in this reactor through which radioactive wastes and normal wastes would pass. One would go into a special container, the other went straight into the drains. After the emptying of more than ten cubic metres of radioactive liquids, the special container was still empty. The reason was that the gate leading to it was still closed, while the one leading to the normal drain system was open. (N. Thieberger p5)
