[en] This paper analyzed the final declaration adapted at the sixth review conference of the parties to the treaty on the non-proliferation of nuclear weapons held at UN headquarters in New York, from 24 April until 19 May 2000 and prospects international nuclear trends

[en] Korea has traditionally experienced very low doses(1.0 man-Sv/unit) to workers in the nuclear power plants. These results have been achieved by taking various measures on the efforts of dose reduction. This paper will describe the trends of occupational radiation exposure and discuss the action that were being implemented to reduce the dose. Based on this situation, we will establish the dose reduction plan next 10 years

[en] One of the top-tier requirements for the development of Korean Next Generation Reactor (KNGR) was set to make it possible to simplify emergency planning technical basis for this requirement is based on the use of new source term, the safety increase such as the reduced core damage frequency, and the enhanced containment performance. The probabilistic method was used to evaluate the distance meeting protective action guideline's dose criteria for emergency planning simplification based on the current KNGR design

[en] Credibility of thickness data is very important in the thinned pipe management program. This report presents following criteria; thickness measurement for each pipe component type, wear and wear rate calculation, and remaining service life assessment of thinned pipe component. And, the necessary items should be contained in the inspection report are presented

[en] A major objective of the study is prescribing instrument performance through analyzing on-line signals on instrument channels, deciding calibration period, reducing unnecessary maintenance, decreasing equipment damage. Through using neural networks for sensor signal validation method and SPRT for statistical performance evaluation method which is one of the most important issues in system performance analysis on instrument channels, detect drift and fault of instrument, deciding calibration period, a better system maintenance for instrument calibrations will be discussed

[en] Under the strengthened safeguards system, the IAEA applies all available information technology and open source information to verify the correctness and completeness of the declaration of the Member States and monitor whether there are undeclared nuclear activities. Rapidly available commercial satellite imagery which covers wide area is now considered as very useful open source information. Nowadays panchromatic commercial satellite imagery has 1m spatial resolution and can be applied in the field of safeguards. This paper treats the basis of the IAEA's application of satellite imagery taken on the Member States, status of satellite imagery, potential application of satellite imagery in international safeguards and our preparation to this trend

[en] The development of the integrated technology including fabrication of corrosion defect specimens and their practical use is needed to enhance the reliability of eddy current test for nuclear steam generator tubing. In this paper, ECT characteristics are evaluated comparing with destructive examination for two kinds of natural flaw specimens simulating PWSCC and IGA of alloy 600 steam generator tube
