  • In order to acquire a realistic forecast for the lifetime and post-closure period of the LILW (Low- and Intermediate-Level Radioactive Waste) repository and to establish the overall management plan associated gas issues. it is essential to carry out the long-term experimental research in a similar condition to actual disposal environment. Regarding this, as a part of the following-up actions on a construction and operation license for the first stage of the LILW repository at Gyeongju city, a large-scale in-situ experiment is being planned. For securing basic data on the experiment, the experimental researches related to gas generation previously performed in foreign countries are reviewed in detail. Consequently, it is judged that data on the gas generation experiment in Finland could be practically applied as the benchmark for our large-scale in-situ experiment because the same disposal concept as the Korean repository is adopted and the experiment is performed in a scale large enough to allow the use of regular waste packages.

  • The Irradiation test of bar code label tagged on radioactive waste container was done to determine the effect of radiation. Low and medium radioactive waste is that below total activity of 4,000 Bq/g according to the Korean nuclear law. The irradiation amount to radiate bar code label tagged on radioactive waste container was calculated by MCNP-4b computer code. The nuclide such as Co-60 and Cs-137 was assumed to contribute 50% of total activity. Real irradiation amount for bar code label was finally calculated by the dimensions of the container and the bar code label. The Identification of post and the physical deflection of irradiated bar code label was tested by the bar code reader. The coated bar code label was suitable to use on low and medium radioactive waste container.

  • 방사성폐기물 처분후 처분장에서는 금속의 부시, 셀룰로스의 미생물분해, 방사선에 의한 분해등으로 인하여 기체가 발생하게 된다. 이 논문에서는 저준위 폐기물 수송시스템에서 고려하고 있는 폐기물모듈 개념중 6-Pack 모듈을 사용하여 치분할 때 기체발생에 미치는 영향을 평가하여 보았다. 계산은 방사성폐기물 처분장에 대한 초기 건설용량으로 고려중이었던 10만드럼 용량의 처분장을 기준으로 수행하였다. 평가결과, 6-Pack 모듈을 사용하여 처분할 때 6-pack 모듈을 사용하지 않고 처분하는 경우에 비해 H$_2$의 발생량은 1.4배 정도 증가하며, $CO_2$, CH$_4$ 등에 있어서는 영향이 거의 없는 것으로 나타났다.
