ac':ident from other countries, spokesmen for the USSR have asserted that the U.S. did a poor jcb itself in this area during the accident at Three Mile Island.

4 In fact, the Nuclear Regulatory Commission took extraordinary steps to inform other countries of available information concerning the TMI accident, although it was far less severe than the Soviet accident and had no radiation impact on foreign countries.

On March 28,1979, the first day of the TMI accident, in addition to extensive phone contact to keep our regulatory informat.fon eu.hanye ver Lners informed, NRC send advicory telegrams through the State Department to 22 countries which were operating or con-sidering the use of U.S.-type rcactors to inform them of the magnitude of the accident, radiation releases. and malfunctions and operational actions at TMI as ouickly as these became kncWn. This was to enable them, if appropriate, to take precautions at their plants. The IAEA and the NEA received these notices from Day 1 as well. The list of countries receiving advisories was expanded March 30 to include Canada.

Updates were sent to all of these countries plus the IAEA and the NEA almost daily for the first two weeks.

A site visit and briefings were also arranged by NRC for foreign nuclear safety officials in the first week after the accident (on April 3,1979), and extensive follow-up information on the causes of the accident as these became better understood was provided for interested countries and international organizations in the months after the accident with the aim of learning from the event any lessons on how to improve nuclear safety in the future.

For its information efforts, NRC received expressions of gratitude and appreciation from the Governments of Belgium, Canada, France, the Federal Repubite of Germany, India, Japan the Netherlands, Sweden, and the United Kingdom as.well as from the Nuclear Energy Agency.
