After their service life is over, nuclear power plants must be decommissioned. Accordingly, Sweden has a system with segregated funds to cover the costs. Payments to the funds are dictated by the results of recurrent cost estimates. Recently, differences have been observed between different estimations for the Barsebäck BWR:s. Therefore, the Swedish Radiation Safety Authority, who oversees the ...

In order to realize an autonomous nuclear power plant, the sensing system performing daily inspection inside of the plant is indispensable. For the sensing system, reliability and exibility are demanded to cope with risky and complicated environments. In order to build such sensing system, we have been emphasizing the importance of cooperation and active control of various sensing functions, an...

Recently, especially after the 2011 off the Pacific coast of Tohoku earthquake and the Fukushima Daiichi nuclear power plant accident, the need for treating residual risks and cliff-edge effects in safety-critical facilities has been widely recognized as an extremely important issue. In this article, the sophistication of seismic designs in safety-critical facilities is discussed from the viewp...

Background: China's inland nuclear power plants plan has been suspended until 2015 since Fukushima disaster. The policy on inland nuclear power plants becomes uncertain. This paper provides an overview of inland nuclear power plants the safety grantee, economic power on diminishing disparities between Western China and Eastern China, efforts on environmental improvement with reforming of energy...

Recombination was used to construct 22 two- or three-way combinations of down- and up-mutations in Pant, a strong, near-consensus promoter of phage P22. The relative strengths of these promoters in vivo were assayed by fusing them to an ant/lacZ gene fusion and measuring beta-galactosidase levels produced by lysogens carrying the fusions on single-copy prophages. The results of these assays sho...

Since it is necessary for leg bags to be emptied several times daily, independence in urinary drainage is essential if a quadriplegic person is to be left unattended for more than a few hours, This goal is often overlooked, however, in an initial rehabi Ii tation program. Conventional approaches to leg bag emptying involve lifting the leg ontoa toilet seat or leaning down to empty the bag into ...

For a country that does not yet use nuclear power, the introduction and development of nuclear power is a major undertaking. It requires the country to build the necessary infrastructure so it can construct and operate a nuclear power plant (NPP) profitably in a safe, secure and technically sound manner. A major part of the necessary infrastructure is the electric grid to which the NPP will con...
