[en] The article deals with the study of nuclei made to spin at very high rates, some change from superfluid state at low spin speeds to solid behaviour at higher spin rates. At even higher spin rates even very stable nuclei alter shape and if the speed is high enough the nuclei is split into two parts. (J.H.H.)

[en] Denmark's second reactor, DR 2, whose first criticality took place the night of 18/19 December 1958 was shut down for the last time on 31 October 1975. It was a light-water moderrated and cooled reactor of swimming-pool type with a thermal power of 5 MW, using 90% enriched uranium. The operation is described. The reactor and auxiliary equipment are now being put 'in store' - all fuel elements sent for reprocessing, the reactor tank and cooling circuits emptied, and a lead shielding placed over the tank opening. The rest of the equipment will remain in place. (B.P.)

[en] The present paper gives a Danish summary of USAs legislation concerning seismic and geologic siting criteria for nuclear power plants (Code of federal regulations, 10, Energy: Chapter 1 - Nuclear Regulatory Commission (NRC), 514 pp.) and evaluates the possibility of application of American procedures in Denmark.

[en] All isotopes belonging to the elements Technetium (Tc) and Promethium (Pm) are unstable against beta radiation, neither element is therefore found in nature. The author presents the beta decay energies for the isotopes and discusses them in the context of liquid drop models and shell models. (J.H./G.T.H.)

[en] The article deals with energy consumption, energy reserves and air pollution in relation to the Danish National Account. The statistics are taken from the separate environment account, which is consistent as 'satellite' to the real national account. The environmental account from Denmark is an example of a system of the so-called NAMEA-type (National Accounting Matrix including Environmental Accounts). (EHS)

[en] The energy balances of the Danish Statistical Office are the designation of the goods balances, which are tabulated for each energy article in both physical entities (quantities) and in base rates (values). The balance concept is connected to the definition supply = use, which is the basis for the construction of the system. The supply is determined as the sum of two items: import and production while the total use is the sum of 138 items: export, waste and transmission loss, stock increase, input in lack of the 130 industries, and private consumption divided into 5 consumption groups. The statistical analysis is performed yearly in both quantities and values for 35 energy articles. Values are computed for base rates, profits, taxes, VAT and market prices (buyer's price), respectively. The energy balances from 1975 to 1998 are presented for comparison. (EHS)

[en] In preparation for reducing the CO2 emission and in so living up to the Kyoto-protocol with the succeeding changes, renewable energy has - including photovoltaic - got an increasing importance in the world over - especially in Germany. If the technical potentials in Germany are utilized optimally, then 75% of the total German electricity production with photovoltaic are covered. At the moment it is only about 1 per thousand. There is a political will to promote photovoltaic in Germany, which results in high account prices and different plant supporting programmes. In the coming 6 years the official aim is that a minimum of 100.000 photovoltaic power plants are installed with an average capacitate for 3 kWp. The competition for the market is hard. There are many national and international suppliers, so the co-operations between the large German producers seem to be obvious. (EHS)
