- W1974497789 abstract "본 연구에서는 방사성 폐기물 처분장 설계 시 필요할 수 있는 공기 유동 방향의 제어에 이점을 가진 Diagonal 환기 회로에 대해서 연구하였다. 연구 결과, Diagonal 환기 회로에서도 Diagonal 갱도(Branch)로 유입시킬 공기량과 공기 유동 방향을 미리 정한다면 다른 직 병렬 회로와 마찬가지로 수식이나 프로그램에 의한 공기량을 산정할 수 있음을 알 수 있었다. 이를 적용하기 위해 앞으로 처분될 고준위 방사성 폐기물의 추정 데이터를 통해 Diagonal 환기 회로와 병렬식 환기 회로가 적용된 고준위 방사성 폐기물 처분장의 설계안을 마련하였다. 마련된 설계안 별 비교 및 예상 운영 결과를 얻기 위해서 환기 네트워킹 프로그램인 Ventsim 프로그램을 통해 환기 네트워크 시뮬레이션을 수행하였다. 그 결과 저항 증가가 큰 수치로 발생할 것으로 예상되었던 Diagonal 처분장은 병렬식 환기 회로가 적용된 처분장과 비교하였을 때, 팬 압력은 1570 pa, 총 유량 84 <TEX>$m^3/s$</TEX>, 팬 효율 76.4%, 팬 소요 전력 181.2 kW 및 연간 팬 운영 비용 178,710,838원으로 압력과 유량값에서 최대 8% 정도의 차이를 보였고, 운영 비용 측면에서는 1.5%의 차이를 보였다. In this study, diagonal ventilation circuits that are advantageous in air flow direction control were studied. Based on the results of the study, it could be seen that air volumes in diagonal ventilation circuits could also be calculated using numerical formulas or programs if the air volumes and air flow directions to be infused into diagonal branches are determined in advance as with other serial/parallel circuits. To apply the results, design plans for high level radioactive waste repositories applied with diagonal ventilation circuits and parallel ventilation circuits. To compared the each design plans and obtain expected operation results, ventilation network simulations were conducted through the Ventsim program which is a ventilation networking program. Based on the results, in the case of diagonal repositories that was expected to cause great increases in resistance, fan pressure was 1570 pa, total flux was 84 <TEX>$m^3/s$</TEX>, fan efficiency was 76.4%, fan power consumption was 181.2 kW and annual fan operating costs were 178,710,838 and thus maximum around 8% differences were shown in pressure and flux values and a difference of around 1.5% was shown in terms of operating costs." @default.
