소각 또는 고온용융 등의 열처리 설비의 운전시 이로부터 예상되는 작업자 및 인근주민의 방사선 피폭을 보수적인 개념과 단순화시킨 피폭예측 식을 이용하여 산출해 보았다. 200kg/hr 용량의 소각로에 대해 발전소의 가연성 폐기물을 소각하는 경우 작업자의 피폭이 인근주민보다 훨씬 우려해야 하는 영향인자였으며 소각대상물 중의 핵종농도의 제한, 소각재 취급시 차폐의 증대 등이 요구된다. 따라서 작업자의 최대 피폭허용기준치를 기초로 폐기물내 핵종의 최대 허용 비방사능치를 계산해 보았고 각 핵종의 영향도를 제시해 보았다. 적용된 식은 각종처리 및 처분시설의 설계 및 운전전에 안전성 평가에 활용될 수 있으리라고 기대된다.

The amount of radioactive waste is expected to be increased continuously because of the rapid growth of the domestic nuclear industry, full power operation of the HANARO reactor and the increased research activities of the nuclear fuel cycle. Accordingly the efforts are focused to achieve the handling of radioactive waste in safe and reduce the volume of radioactive waste. The PIEF is carrying out the PIE (post irradiation examination) of spent fuel rods related to the identification of cause defect and evaluation of integration safety. This study describes the technologies and experiences of compaction, shredding and cutting of the solid radioactive waste used in the PIE. The quantity of the high level waste was reduced by 1/12 using the 100-ton compressor installed in hot-cell. Also middle and low level waste was reduced by 1/8 using the 60-ton compressor installed in intervention area. Plastic drums were shredded by crusher to be compacted in the ratio of 1/5, used filters in the ratio of 1/6 and the number of drum is also reduced by cutting procedure for the non-volatile materials such as metal.

The purpose of this study was to investigate the possibility of an alternative fuel resource by incinerating a mix of combustible MSW (municipal solid waste) and offals after separating recyclable material at the MRF (material recovery facilities) location. We analyzed the physical and chemical properties including the 3-contents, the calorific value, and chemical compositions of the separation rejects in MRF, and compared the results with combustible MSW. Moreover, we experimented the trend of combustible properties and the concentration change of air pollutants at mixed incineration in the MSW incinerator. According to the results of the experiment, the separation rejects showed higher heating value (5,865 kcal/kg), and lower moisture and ash content than combustible MSW. Since we have incinerated MSW in the MSW incinerator mixing the offals at 30% and 50% respectively, we know that the change of the concentration of dust, $SO_2$, $NO_2$, and CO did not appear significant, and not exceed the pollutants emission regulation. But, considering the enhancement of the HCl emission concentration (max. 33.7 ppm) at the co-incineration of the 50% offals, we believe that the proper mixing ratio of the separation rejects would become within 30%.
