UNCLASS!ie INTERNATIONAL ACTIVITIES rs -_—_— -— oo utility, were expected to agree shortly ona contract for the construction of a 200,000-electricalKilowatt power reactor at Latina, near Rome, as well as a 7-year agreement for cooperation providing for technical information exchange. Japan. The United Kingdom —Japan power bilateral agreement, long stalemated onthe third party liability issue, was signed on June 16, the same day as the agreement with the United States. It was reported that there was considerable public criticism in Japan of the Japanese Government's decision to purchase a Calder Hall—type power reactor from the United Kingdom. A Kyoto University meteorology professor has written a paper titled “A Dynamical Theory of the Microbzrographic Oscillations Produced by Explosions of Hydrogen Bombs,” dealing with studies of alr wave recordings {n connection with 29 nuclear tests from 1952 to 1857, The shock waves are categorized by four types of test explosions and related to specific detonations. Sweden. Negotiations were reportedly in progress between Swedish and Finnish atomic energy companies concerning possible sale to Sweden of all uranium ore mined in Finland. Sweden’s own production was expected to yield about 100 metric tons of uranium peryear after completion of a new processing plant under construction, United Kingdom. A white paper issued by the United Kingdom in Apri] revealed that the target date for completion of the 5,000,000- to 6,000,000-kilowatt nuclear power program had been delayed one year, to 1966 instead of 1965, and that a higher proportion of the total new generating capacity required.between 1958 and 1966 would be in the form of coal-fired stations with lower capital costs. . . The Dounreay Materials Testing Reactor (DMTR) went critical May 24, When fully operative it will run at 10,000 kilowatts. DMTRis the first of three reactors at Dounreay; the other two are a fast breeder reactor housed in a giant sphere and the Admiralty’s land-based submarine propulsion reactorprototype. _ At a press conference the United Kingdom Atomic Energy Authority gave details of the latest experiments with their Zero Energy Thermonuclear Assembly (ZETA) at Harwell, showing that at least 95 percent of the neutrons produced by ZETA were not thermonuclear in origin, This refuted general public assumption that true thermonuclear neutrons had been achieved in ZETA. However, Harwell did not plan to change the direction of its controlled thermonuclear research program. Yugoslavia. Yugoslavia’s first nuclear reactor, a zero power facility using natural uranium and heavy water acquired from the Soviet Union but otherwise built by the Yugoslavs themselves, was officially dedicated May 17, after having achieved initial criticality in April. The reactor is located at the Boris Kidric Institute for Nuclear Sciences at Vinca. A larger reactor of 10,000 kilowatts was being built with Soviet assistance, with completion scheduled for late 1958. There were indicaticns, however,that this project was behind schedule. ll TECHNICAL = XCHANGE AND ASSISTANCE Australian Symposium A seven-rman AEC delegation participated in the Australian Symposium on the Peaceful Uses of Atomic Energy held at Sydney, June 2—6, and presented seven papers. The group remained in Australia for an additional week as an AEC technical mission and conferred with Australian atcmic energy personnel on legal and administrative aspects of nuclear energy, experimental power reactor technology, uranium fabrication, chemical processing, and radioactive ~este disposal.
