I thought it would be helpful for those concerned with the proposed conference in Ottawa if we gave you a little information additional to that contained in my WA-1234 of May 6th on the subject matter expected to be covered in the proposed conference. I asked Ignatieff therefore to find out from Arneson what the U.S. views on the proposed agenda are. 2. As indicated in my WA-1234, the main purpose of this conference is to provide an opportunity for the U.S. authorities to ascertain how effective in practice the new U.K. security clearance procedures are, before undertaking what the U.S. regard as a substantial step forward in a further measure of technical co-operation In the highly-classified field of atomic energy information under the amended U.S. Atomic Energy Act. 3. Thoy do not propose that the new conference should go over the general ground of comparing security standards which ware so exhaustively covered in the two preceding security conferences. The agenda, Arneson thought, would in substance consist of two main points; (a) statements by the three delegations on any significant changes In security procedures in their respactive countries, including clearance, investigation arrangements and materials safeguards, instituted since the last meeting in London last July, and (b) consideration in particular of the effectiveness of the new arrangements instituted in the U.K. 4. As regards (a), Arneson thought that each delegation would make brief reports on any significant changes in their security programs. Done — Date 20M-SO-P-794 000235 �Document disclosed under the Access to Information Act Document divulgue en vertu de la Loi sur I'acces a I'informatioi - 2 The U.S. delegation would have two changes to report. In a bill passed by Congress on April 5, 1952, certain investigation responsibilities have been transferred from the F.B.I, to the Civil Service Commission. This new legislation, which the U.S. authorities will explain at the meeting, is apparently designed to lighten the load of investigation of normal applicants for jobs in the USAEC as well as other departments and agencies handling "sensitive" Information, leaving, however, the discretionary authority to apply F.B.I, investigations in special cases. The second change relates to an arrangement between tho USAEC and the Department of Defense whereby certain military personnel cleared under military procedures up to top secret may be given access in line of duty to "restricted data" under the meaning of ths MeMahon Act on a need-to-know basis. 5. As regard (b) the question of assessing the effectiveness of the new security procedures in the U.K. obviously presents difficulties. Arneson said that no formal conclusions can be expected from the conference, but it is hoped that after some frank discussion on a number of questions which would be put to the U.K. delegation, the USAEC and the F.B.I, will be enabled to give the requisite assurances to the Joint Congressional Committee about the . effectiveness of the new British security procedures. Arneson mentioned the kind of questions which he thought the U.S. delegation might direct to the British delegation with regard to their security questionnaire: (a) Why does it not ask for the names of other close relatives of applicants, such as brothers or sisters? (b) Also ex-spouses, if any. (c) Why does it not ask for details on schools and colleges attended? (d) Why is there no mention of prosecution for false statements or omission of information. (The only reference in the British form is to disqualification or disciplinary action, such as dismissal.) 6. The U.S. authorities also expect to exchange views on the evaluation of information obtained by this type of questionnaire. They are thinking In terms of working out a number of hypothetical replies to questionnaires and then going through such hypothetical cases in detail exchanging views on the evaluations given by the respective delegations.
