[en] Polished rice was collected in producing districts at the harvest and in consuming areas when new crops were first put on sale. The sample was carbonized and ashed in a porcelain dish. The results obtained from December 1978 to December 1979 were shown in a table. (J.P.N.)

[en] The XUNDL database provides prompt Internet access to recently published or completed primarily high-spin level scheme data that are not yet available in ENSDF database. The database is not limited to high-spin papers, there are some low-spin compilations also. The database is indexed by mass number, nuclide and reference key number. Since January 1999, 585 data sets were added to XUNDL, mostly from papers published in the period 1998 to 2000

[en] The samples of service water, 1000 l each, were collected at the intakes of water treatment plants and at taps after water was left flowing out for 5 min. The carriers of Sr and Cs were added immediately after the sampling, and the samples were vigorously stirred and filtered. They were passed through cation exchange columns. Sr and Cs were eluted with hydrochloric acid from the cation exchange columns. The methods of separating Sr-90 and Cs-137 from the sample solutions are explained, and their activities were counted with low background beta counters for 60 min. The net rate of sample counting was corrected for the counter efficiency, recovery, self-absorption and decay. As the environmental data, the results of Sr-90 and Cs-137 in service water obtained from December, 1978, to December, 1979, and the locations of sampling are given. In a table, the months and the locations of sampling, pH, and the amounts of Sr-90 and Cs-137 (pCi/l) are shown. The maximum values are 0.49 pCi/l of Sr-90 in tap water found in Wakkanai in December, 1978, and 0.04 pCi/l of Cs-137 in tap water found in Mito in May, 1979. (Kako, I.)

[en] The analysis of Light Water Reactor (LWR) Loss-of-Coolant Accidents (LOCA's) requires that one be able to accurately calculate the two-phase flow splits in complex, branching conduits. The purpose of this study is to provide a general method for calculating the phase separation in a branching conduit. The degree of phase separation of a two-phase (air/water) mixture flowing through a plexiglas tee test section was measured. In addition, flow visualization, using high speed photography, was performed. The experimental design considerations, error analysis and the dependence of the observed phase separation on global parameters, such as inlet quality, mass flux and separation angle, are discussed. The pressure gradients were measured along the various conduits and the differential pressure was obtained at the tee junction by extrapolation. It was found that the degree of phase separation was quite pronounced, with the vapor phase preferentially separating into the branch. Using these data, a physically-based empirical model was developed with which to calculate the phasic distribution of a subsonic two-phase mixture in the downstream branches of a branching conduit

[en] Magnetospheric radio noise spectra (30 kHz to 10 MHz) taken by IMP-6 and RAE-2 exhibit time-varying characteristics which are related to spacecraft position and magnetospheric processes. In the mid-frequency range (100 to 1000 kHz) intense noise peaks rise by a factor of 100 or more above background; 80% of the peak frequencies are within the band 125 kHz to 600 kHz, and the peak occurs most often (18% of the time) at 280 kHz. This intense mid-frequency noise has been detected at radial distances from 1.3 Re to 60 Re on all sides of the Earth during magnetically quiet as well as disturbed periods. Maximum occurrence of the mid-frequency noise is in the evening to midnight hours, where splash-type energetic particle precipitation takes place. ''Magnetospheric lightning'' can be invoked to explain the spectral shape of the observed spectra

In the midfrequency range (100-1000 kHz) intense noise peaks rise a factor of 100 or more above background; 80% of the peak frequencies are within the band 125 kHz to 600 kHz, and the peak occurs most often (18% of the time) at 280 kHz. Bandwidths of the peaks range from about 100 kHz to more than 500 kHz; most often the lower cutoff is at about 100 kHz and the upper at 380 kHz for a total bandwidth of 280 kHz. This intense mid-frequency noise was detected at radial distances from 1.3 Re to 60 Re on all sides of the earth (i.e., all local times) during magnetically quiet as well as disturbed periods. Maximum occurrence of the mid-frequency noise is in the evening to midnight hours where splash-type energetic particle precipitation takes place

[en] Fish was rinsed with water and blotted with a filter paper. Only the edible part was used in case of larger sized fish, and the whole part was used in case of smaller ones. Each sample was weighed and placed in a stainless steel pan or a porcelain dish. After carbonized, the sample was ashed in an electric muffle furnace. The results obtained from December 1979 to December 1980 were shown in a table. (J.P.N.)

The activities of various radioisotopes are presented in tables

[en] Since the Fukushima accident, the concern has increased internationally about the disaster and the severe accident. In particular, the importance of severe accidents prevention and mitigation has been highlighted. KHNP is pushing for the development of integrated safety analysis codes applicable to multiple failure accident. It is necessary to the extension development of a code for apply the multiple failure accident to the SPACE which is developed for thermal analysis of domestic PWR. In order to apply the SPACE code to multiple failure accident, the PIRT(Phenomena Identification and Ranking Table) has to develop considering the physical phenomena expected in multiple failure accident. It developed a major thermal-hydraulic phenomenon PIRT for ATWS accidents for expanding the SPACE code to apply to the design extended conditions. The major scenarios and the major thermal-hydraulic phenomenon of the system/structure and the component were derived through the developing the PIRT. PIRT was able to derive the thermal-hydraulic model needed to expand the SPACE code.
