하나로에서 발생하는 방사성폐기물은 물리적 특성에 따라 고체, 액체 및 기체 방사성폐기물로 분류된다. 고체 방사성폐기물은 방문객 및 종사자들의 원자로실에 출입하여 업무를 수행하는 과정에서 발생하며, 액체 방사성폐기물은 계통의 누설, 보수작업, 실험장비 설치 등의 원자로 운영과정에서 주로 발생한다. 본 논문에서는 2005년도 하나로 시설의 방사선 관리 구역인 원자로실에서 발생된 고체, 액체 방사성폐기물의 발생량과 이들의 저감화를 위하여 취한 조치를 기술하였다.

하나로에서의 방사성폐기물은 작업공정 특성상 원자로 정기점검(overhaul)시 주로 발생된다. 이에 방사성 폐기물의 발생을 최소화 하고, 규제해제대상 폐기물의 지정 및 분류를 해야 한다. 본 논문에서는 방사성 폐기물의 종류 및 특성을 고려하여 작업절차의 개선, 저감화 대책 및 이를 적용한 실적을 소개하고자 한다.

The quantity of liquid waste produced during HANARO operation for the years from 1996 to 2002 has been investigated and the interrelation with the reactor power output has been analysed. The waste amount produced during this period was $263, 530{\ell}$ and the processing expense was 81, 690, 000 won. The waste amount and processing expense per reactor power output are $11.38{\ell}/MWD$ and 157 won/MWD, respectively. The waste has been reduced by improving repair work procedure and experiment process in the reactor hall.

In 2002, the waste was generated about 277,533tons per day. The treatments of waste were recycling, which had accounted for almost 70%, landfill, which had accounted for 19.8%, and incineration, which had accounted for 6.5%. The energy recovery from incineration has been increased since 1995. The portion of waste in the renewable energy has been increased. Waste incineration heating system generates total 134TOE of $CO_2$ as compared to 6,800TOE of GHG from LNG boiler centralized heating system to bring 98% reduction rate of GHG emissions. We need the integrated model to examine the impacts of waste managements on economy and environments. The Asia-Pacific Integrated Model is introduced as the example of the integrated model.

1990년 이후 생활폐기물보다 사업장 폐기물이 많아지면서 총 폐기물 발생량은 점차 증가하고 있는 상황이다. 날로 증가하는 폐기물을 국내 실정상 매립처리하는 것은 한계가 있으므로, 효율적인 감량화 정책으로 폐기물 발생량을 저감하고, 소각에 의한 처리가 요구된다. 그러나 폐기물 소각처리는 소각 재와 유해가스를 배출하기 때문에 많은 문제점이 있다. 특히 인체에 맹독성인 다이옥신류(polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans:PCDD/Fs)가 배출되면서 현재 사회적 문제로 크게 부각되고 있기 때문에 소각시 다이옥신을 처리할 수 있는 장치의 개발이 필요하다.

A lot of particulate matter and an offensive odor are emitted during the operations of an industrial waste incinerator (IWI), especially pre_treatment and waste input processes. These pollutants affect the labor efficiency of an operator. Therefore, in this study. we have studied the improvement of working surroundings in the industrial waste incinerator by designing a new control system. A computational fluid dynamics has been used to find the diffusion flows of air pollutants (mainly particles and odor) to the working surroundings of the waste treatment complexes. The results obtained from the simulation analysis applied to the basic design on the points (and/or site) and types of pollution control devices. When pollutant control devices are constructed, the concentration of each pollutant at site 1 and 2 decreased about 83-97% for toluene, 48-72% for styrene, 75-87% for xylene, and 23-36% for ammonia, respectively. In addition, the PM-10 and TSP were decreased about 87% and 86% at site 3 (lower part of the waste input), 87% and 85% at site 4 (side part of the waste input), respectively. These indicated that the new control system had an excellent performance of particulate matter and odor removal and it could be applied to other waste treatment plant in place of an industrial waste incinerator.

These days many companies are trying to reduce, recycle and reuse their wastes. Even though many wastes can be recycled, those are incinerated or landfilled. To solve these problems, there are many projects to make efforts to recycle wastes in especially the industrial complexes. But, due to the absence of information about waste recycling, recyclable wastes are still incinerated or landfilled. Based on these research background, this study aims to suggest the evaluation methodology of the $CO_2$ emissions and cost reduced by circulating the industrial waste to resource. We evaluated the environmental and economic effect between companies which emit the plastic waste and organic solvent waste and use them as raw-materials in the off-line recycling information exchange network. The environmental and economic aspects were analyzed comparing waste recycling with waste incineration. By recycling the plastic waste as raw-materials, $CO_2$ emission were reduced 1,070 ton in 2009 and 1,234 ton in 2010 and 657.4 million won in 2009 and 755.0 million won in 2010 were reduced. In recycling the organic solvent waste, 7.3 ton-$CO_2$ in 2010 and 5.6 ton-$CO_2$ in 2011 were reduced and 15.9 million won in 2010 and 12.2 million won in 2011 were reduced.
