- Cooperation with France
The President has directed that discussions with the Government of France concerning nuclear safety cooperation (currently being conducted under NSDM 104) be expanded to include assistance in the area of underground testing. The purpose of this expanded program is to provide assistance for French efforts to increase nuclear safety in underground testing and to encourage the French to refrain from further atmospheric testing through the adoption of an underground testing program for all of its nuclear explosives tests. In implementing this expanded program, technical information on instrumentation, containment, and other pertinent technology which will serve to improve the efficacy of the French underground test program may be exchanged. The President has authorized disclosure of unclassified information and classified information through Secret, but not including Restricted Data, for this purpose.
Discussions with the French Government concerning nuclear safety in other areas may be continued within the limits provided in NSDM 104. The President has decided that no French nuclear explosive devices of any type may be accepted for test by the US.
In specific implementation of this decision, the President directs that:[Typeset Page 1017]
