" Principal Actions Taken in France Following the Accident at Unit 2 of the Three Mile Island Nuclear Power Plant on March 28, 1979," November 20, 1979, 9 pages.
Available in English.
This report describes the several French missions which visited the U.S. in the conths following the accident at TMI, while detailing the measures the French nuclear authorities have decided to take concerning (a) the safety of nuclear installations, (b) actions by public authorities in the avent of an accident comparable to TMI, and (c) public information.
"L' Accident de Three Mile Island," a sumary written by Pierre Tanguy, Director of the Department of Protectica and Nuclear Safety, for publication in the l
CEA's Note d'Infomation, April 1979, 6 pages.
Available in French only.
This is an early sumary of the TMI accident, written from information available in France in April 1979.
It contains a brief comparison of French (Westinghouse) and B&W reactor systems, as well as an early plan of action to assure the safety of French nuclear power plants.

This report was largely inspired by the findings of the official Ministry of Industry study mission, which visited the U.S. April 29 - May 5,1979.

Available in English.
This paper, published in the Bulletin of Radiation Protection (Volume 2, No. 3, July-September 1979), briefly traces what happened at TMI -- and why -- from the standpoint of radiological significance.
It notes that, for an accident that rocked the world, damage to health and property was surprisingly small, and looks for the 23 recommendations of the Lessons Learned Task Force to provide substantial additional protection of the public health and safety.

. SWITZERLAND, The March 28, 1979 Accident at the American Three Mile Island Nuclear Power Plant at Harrisburg: Second Interim Report of the ASK, August 10, 1979, 58 pages.
Available in English.
This report presents a preliminary analysis of the TMI accident performed by the Department of Nuclear Power Plant Safety (ASK), as well as a description of the measures taken by ASK to improve the safety of nuclear power plants in Switzerland.
It also contains the following brief statement about the Beznau " precursor" event:
"KKB [Bezr.au] is the only Swiss NPP with primary-side relief valves.
Due to the plant design which in comparison with Harrisburg is much less vulnerable, the opening of the relief valve is here a very rare event. Approximately five years ago during actuation of one of these relief valves it became jammed in an open position due to an error in design which was subsequently corrected. Nonetheless the personnel on duty detected this malfunction within a few minutes and locked the isolation valve in front of it.
The short-term loss of coolant had no further consequences. As a short-term measure nonetheless an automatic circuit was constructed which locks the isolation valve in the same line if the relief valve failed to lock; at Harrisburg this isolation valve was closed by the operator only after 2 hr 20 min."

Available in English.
This letter and accompaniment were circulated to the citizens of Switzerland by the Government Council of the Canton of Aargau to provide them with information on actions they should take to protect themselves in the unlikely event of a nuclear power plant accident.

Department of Health for responding to nuclear disturbances, either at the plant or in transit.

.. e UNITED KINGDOM The Accident at Three Mile Island: Comments by the Health and Safety Executive, December 17, 1979, 11 pages.
This interim review of the TMI situation by the U.K. Nuclear Installations Inspectorate reaches the following general conclusions:
l 1.
The accident did not arise from any serious inherent weakness in the concept or design of the PWR (so Britain need not alter its announced PWRplans).
2.
No fundamental revisions should be necessary to Britain's organizational arrangements for licensing, constructing, or operating power reactors, which are already similar to those recomended by the Kemeny Commission.
3.
There are detailed lessons to be learned in the areas of human error, training, and emergency plans.
It seems desirable for the HS&E to establish and publicize more thoroughly its arrangements at the national level.
4.
Additional emphasis is needed on a range of detailed subjects such as instrument performance in emergency conditions, information presentation to control room operators, and communications in general in the period imediately following an accident.
5.
The Executive will be taking into account the information and recomendations in the reports already (and to be) published in its work of licensing future reactors and inspecting existing ones.
This is the report which also asserts that " training arrangements are already better in Britain than they were at Three Mile Island."
"Three Mile Island Incident: Notes of a Visit to the U.S.A.,10 to 16 July, 1979," by Ronald Gausden and John Macleod of the Nuclear Installations Inspectorate, 7 pages plus attachments.
This report sumarizes information gained during informal discussions held by the authors in July 1979 with the principal parties involved in the TMI incident (NRC, GPU, B&W, and the TMI site).
It focuses on regulatory procedures as a means of gaining a better understanding of the accident.
