Ten copies of the Minutes of a tripartite
conference on atomic energy security standards, which
took place in Washington on May 15 and 16, have been
received from the U.S. Atomic Energy Commission (copies
Nos. 16 to 25, Series A ) . We are retaining one copy
(No. 25) and the other 9 copies are enclosed herewith
(Nos. 16 to 24 inclusive).

In forwarding these documents the Secretary of
the U.S. Atomic Energy Commission has requested the
comments and suggestions of the Canadian delegation.
Perhaps you would be good enough to enquire from
Dr. C. J. Mackenzie, Commissioner Nicholson and Mr. J. L.
Gray whether they have any comments to make on the
minutes.
3.
We would also draw your attention to the statement which has been included in the minutes of the last
meeting of the conference which took place at 11:00 a.m.
on Friday, May 16, attributed to Dr. Glennan. This statement, which reads as follows, summarizes in effect the
results of the conference:
"Dr. Glennan said that there was insufficient
experience with the working of the new British
clearance procedure on which to base a considered
judgment of its adequacy. The AEC would not, there*fore, be able at the present time to certify in a
general way that British security standards were
adequate to safeguard restricted data of U. S.
origin. However, from what the U.K. representatives
had said at these meetings he thought that there
were good grounds for hoping that when there had
been further opportunity to see the system at work
on a larger scale, the AEC would feel able to
certify, JJlK#i standards as adequate."
