원자력이용시설에서 발생한 작은 크기의 금속 조각들을 효과적으로 제염하는 스마트 장치를 개발하였다. 이 장치는 자성연 마재를 포함한 영역의 자속밀도를 연속적으로 변화시키는 방법과 초음파를 이용하는 다중 제염장치이다. 한편, 제염 효율을 높이기 위해 제염 장치가 제염 대상 전체에 작용하도록 장치들의 구성을 수정하였다. 개발된 장치들의 최적 작동조건을 도 출하여 샘플로 선정한 소형의 금속방사성페기물에 대하여 자기장과 초음파제염을 각각 15분간 실시하였다. 그 결과 제염계 수의 범위는18~56으로 크게 향상되었으며 제염 후 모든 샘플은 백그라운드(BKG)값 이하로 확인되었다.

‘Hyangdreamchal’, a new early maturing, aromatic and glutinous rice variety was developed by the crop breeding team of Crop Research & Development Division, GARES, Hwaseong, Korea in 2012. ‘Hyangdreamchal’ was derived from a cross between ‘Jinbuchal’ and ‘Miyakaori’ in 2001. This variety headed on July 28 which was 14 days earlier than ‘Hwaseongbyeo’ in Gyeonggi Province. It showed resistance to lodging with strong culm. It's culm length and panicle length were 71 cm and 20 cm, respectively. This variety has 13 tillers per hill and 92 spikelets per panicle. It was medium grain variety and 1,000 grain weight of brown rice was 20.1g. Its cold tolerance was stronger than ‘Hwaseongbyeo’ however it was susceptible to blast virus disease, bacterial leaf blight and insect pest. The milled rice of ‘Hyangdreamchal’ had a glutinous and aromatic endosperm. The yield potential of ‘Hyangdreamchal’ in milled rice was 4.15 MT/ha under the ordinary culture of the local adaptability test in 4 areas of Gyeonggi Province for three years. This variety would be adaptable to the Gyeonggi Province. (품종보호번호 : 제5568호)
