Abstract

During the seven years from 2009 to 2016, PWR SNF (spent nuclear fuel) transportation and storage systems suitable for domestic conditions were developed by the government to cope with the saturation of wet storage capacity in NPPs. One of the developed systems is a multipurpose metal cask applicable for transportation/storage; the other is a concrete cask dedicated to storage. Efficient cask technologies were secured utilizing the characteristics and experience of relevant industrial, academic and research institutes. Technological independence was also achieved through several patent registrations of research outcomes. To prepare for a rapid increase of demand in the near future, technology transfer of secured patents and technologies to the domestic industry was carried out twice in the years of 2016 and 2017.

국내 경수로형 원전의 사용후핵연료 소내 습식저장 용량의 포화에 대비하기 위해 정부 주도로 2009년부터 2016년까지 7년에 걸쳐 국내 여건에 적합한 수송/저장시스템을 개발하였다. 시스템은 운반과 저장을 겸할 수 있는 금속겸용용기와 저장전용인 콘크리트 저장용기로 효율적인 기술개발을 위해 관련 산학연의 특성과 경험을 적극 활용하여 국내고유 모델을 개발하였고 특허 등록을 추진하여 기술의 독립성도 확보하였다. 현재까지 확보한 다수의 특허 및 기술을 산업계에 개방하여 국내 수요에 대처하고자 2016년과 2017년 두 차례에 걸쳐 기술이전도 추진하였다.
