ee 226 OTHER MAJOR ACTIVITIES ground mining of an orebody which has been fractured by a nuclear explosion. Other feasibility studies are being made on using nuclear explosions to stimulate production rates from oil andgasfields of low permeability. Application of nuclear explosives to production of oil from the Nation’s vast reserves of oil shale now appears somewhat more encouraging. Procram DrveELopMENTS Australian Review of Plowshare In response to a Commission invitation, three scientists representing the Australian Atomic Energy Commission were in the United States from September 1 through October 24 to gain a first-hand appreciation of the scientific, engineering, and safety aspects of the use of nuclear explosives for constructive purposes with a view towardassessing the advantages and hazards of their possible use in Australia. Austratian Visitors. Three Australian government scientists made an eight- week tour of AEC facilities during 1963 to acquaint themselves with various peaceful applications of atomic energy.
