[en] This Site Environmental Report for Calendar Year 1996 describes the environmental monitoring programs at the Weldon Spring Site Remedial Action Project (WSSRAP). The objectives of these programs are to assess actual or potential exposure to contaminant effluents from the project area by providing public use scenarios and dose estimates, to demonstrate compliance with Federal and State permitted levels and regulations, and to summarize trends and/or changes in contaminant concentrations identified through environmental monitoring

[en] The deleptonization and cooling times of a newly born neutron star depend on the equation of state (EOS) and neutrino opacities in dense matter. Through model calculations we show that effects of Pauli blocking and many-body correlations due to strong interactions reduce both the neutral and charged current neutrino cross sections by large factors compared to the case in which these effects are ignored.

[en] Steam generator tubing integrity is very important factor for reliable and safe operation of NPP. Several different types of tube degradation mechanisms were experienced in SG operation. To avoid possible tube rupture and primary-to-secondary leak, the EC examination of tubing should be performed. Different eddy current techniques may be used for detecting defects and theirs characterization. A comparison of data analysis results with pulled tube destructive metallography results can provide valuable insights in determining the capability of existing technology and provide guidance for procedure or technology improvements.

[en] It is known that Probabilistic Safety Assessment (PSA) can provide safety status information for a plant during different configurations; but additional effort is needed to do this in real time for on-line operation. This paper describes an approach to use PRA achieve these goals. Equipment Out Of Service (EOOS) tool was developed to monitor nuclear power plant safety from the probabilistic point of view. EOOS is using model developed from a full-scope PRA, and incorporates a user friendly program interface approach. Results from EOOS can be used by planners or operations to effectively manage the level of risk by controlling the actual plant configuration. (author)

[en] The Ministry of Economic Affairs has for six years now been monitoring the operation of the Krsko NPP (NEK) and its impact on the environment. A bulletin titled 'NEK - Energy and Environment' is being issued every three months. It contains information on operation of the Krsko NPP for the previous three months, a graph of duration of temperature increase of water in the Sava river (delta T) in that period, an assessment of the radiological impact of Krsko NPP on the environment through an equivalent dose cumulatively throughout the calendar year, and a short current text related to Krsko NPP. The Ministry of Economic Affairs organizes a press conference on every issue of the bulletin, as an attempt of introducing this subject to the media and to the public. This paper contains a review of information given in the NEK bulletin from 1990 to 1995 with a special emphasis on the contribution of the Krsko NPP to the artificially caused radiation on the border between the Republic of croatia and the Republic of Slovenia.

[en] In the dismantling process of nuclear power plants a large amount of metal residues are generated. The residues of interest are stainless steel, copper and aluminium and can be reprocessed either for restricted or unrestricted use. Although there are many questions about the further use of these materials it should be convenient to recycle them. This paper discusses the complexity of the management of these metals. The radiation protection requirements are the most important principles. For these purposes great efforts in the decontamination have to be made. Regulatory aspects, clearance levels as well as characteristic of steel recycling industry, radiological impact and new developments are discussed. (author)

[en] This issue contains five sessions about radionuclide-bacteria interactions in the presence of metals like uranium and transuranium elements in sediments

[en] This volume contains documents of the 13th and the 14th ITER council meeting as well as of the 1st extraordinary ITER council meeting. Documents of the ITER meetings held in Vienna and Yokohama during 1998 are also included. The contents include an outline of the ITER objectives, the ITER parameters and design overview as well as operating scenarios and plasma performance. Furthermore, design features, safety and environmental characteristics are given

[en] Seeds of Karkade (Al-Rahad variety) were obtained from western Sudan, and investigated perliminary for their chemical composition, the oil of the seed also was investigated. The factors affecting protein extractability such as PH, salt type and concentration and solvent to flour ratio, were studied. The anti nutritional factors investigated were protease inhibitors, gossypol, phytates and tanins, means of inactivation such as heat treatment for trypsin inhibitor and differential solubility for phytates were proposed. Protein fractionation due to solubility was carried out. Other physiochemical properties included polyacrylamide gel electrophersis, ultra violet absorption spectrum and gel filtration pattern. The functional properties investigated were bulk density, solubility, water and oil absorption, emulsifying activity and viscosity. Karkade seed was found to be rich in protein, oil and mineral matter. The amino acid profile of karkade seed proteins indicated the presence of most of essential amino acids in adequate amounts. The relative net protein ratio (RNPR) was found to be 0.75. Protein digestibility-corrected amino acid score of karkade seed protein was found to be 0.63 ( compared to casein in 1.0). The molecular weights of the protein fractions investigated by SDS- PAGE were in the range of 12-82 kDa. UV absorption spectra reflects changes in the molecular structure (native proteins absorb at 280 nm and also interaction with other components e.g. nucleic acids, poly phenols.....etc). Gel filtration pattern reflect changes in molecular size
