1. AEC 532/34 - Classification ProRram @f the Controlled Thermonuclear —. Mr. Mar shall reviewed the recommendation set forth in AIZC 532/34 for a future classification policy for F reject SHERWOOD. He pointed out that under this policy, basic research related to Project SHERWOOD would be unclassified and teclmology important to the development of a controlled thermonuclear reactor would remain unclassified. Mr. Murray inquired whether approval of these recommendations was necessary prior to Mr. Strauss* discussion with Sir Edwin Plowden on September 26, 1956. Mr. Strauss indicated that a decision by the Commission would be helpful in view of the tentative nature of the Commission’s conclusions on the matter at previous meeting. Mr. Libby said that he believed less declas dfication than that recommended wcmld not achieve the re suits which the Commission believed important and therefore he would not favor taking any action if it were not possible to declassify the project to the recommended extent. He also said he believed it is possible to declassify basic information and to retain classification on process technology. In this connection, he referrect to the example of the declassification of the basic gaseous diffusim theory in the Smyth Report. Mr, Vance said he had suggested that the Commission :onsider its positien on the question prior to the meeting with Sir Edwin Plowdea because of the indications of a lack of unanimity in the UKAEA and the possibility that the U.K. would suggest somewhat Ie ss declassification than that recommended in AEC 532/34. He pointed out that the purpose M declassification of &e project is to increase the number of ~cientists who could mntribute to the project and thereby ncrease the chance of a major basic discovery or shorten he time required to achieve a feasible controlled thermomcleas reactor. He added that he would not favor any action - 574 -
