  • 각종 기계장치들은 고속화 및 고출력화 되고 있으며, 사용환경조건은 오염화 및 다양화되고 있다. 이와 같은 가혹한 조건에서 작동되는 기계장치와 설비들에 있어서 냉각장치(cooling system)는 필수불가결한 것이다. 특히, 선박 1척 당 20여개의 열교환기가 필요로 되며, 자동차, 화학플랜트, 원자력발전소, 화력발전소, 제철소 폐열 이용장치 등 많은 곳에서 각종 열교환기가 사용되고 있고 사용 용도에 따라 다양한 환경에 접하고 있다. (중략)

  • 동해 남부 연안에 위치한 울산 정자연안은 울산공단으로부터의 폐수와 생활오수 유입 뿐 아니라, 위로 월성 원자력 발전소, 아래로는 고리 원자력 발전소가 위치하고 있어 수질이 점차 악화되고 있는 곳으로서 생물상의 변화가 예상되므로 정치망에 어획되는 어류를 대상으로 종조성 및 양적변동을 밝힐 필요성이 높아졌다. 어류 군집의 구조를 정확히 파악하기 위해서는 정량적인 채집이 이루어져야 한다. (중략)

  • This study is aimed to construct a marine small hydro power plant using discharge water of fish farm in Jeju Haengwon-ri. The difference of design methods between marine small hydro power plant and land small hydro power plant is to consider the tides. Moreover, ground condition should be examined because gushout sea water comes out from the ground at high tide in Jeju as the ground of Jeju beach consists of basalt stone. From the field test of the turbine generator after construction of the power plant, output power and efficiency of the turbine generator shows good conformance to the required conditions.

  • To evaluate the effects of the cooling water system on the primary production of marine phytoplankton, a series of experiments were made at the cooling water system of Samchonpo Power Plant from May 1985 to May 1986. Mechanical and physiological perturbations of the entrained process are the most detrimental to the primary production of marine phytoplankton. Nevertheless the primary production is increased by the heated water within the upper limit of temperature tolerence of the phytoplankton. The cooling water system, on the average, reduces the gross production and net production by 4.6 to 12.1 and 8.4 to $11.9\;mgC/m^3/h$, respectively.

  • The organically bound tritium(OBT) concentrations of the marine organisms(seaweed and shellfish) around Wolsung nuclear power plants were measured. The OBT concentrations of seaweeds were in the range of $0.372{\sim}2.72$ Bq/kg-fresh. The OBT concentrations of shellfish were in the range of $0.239{\sim}2.02$ Bq/kg-fresh. The internal dose due to the OBT concentration of seaweed was estimated as $3.4{\times}10^{-7}$ mSv/year.

  • This study investigated and compared sediment properties and macrobenthic community structures within heated effluent plumes at the discharge areas of Kori Nuclear Power Plant (KNPP) and Sinkori Nuclear Power Plant (SNPP) in Korea, which have different thermal effluent discharge systems. There were significant differences in sand, clay and organic carbon contents between sediments at the two discharge areas. Species richness and abundance of macrobenthos were higher at the SNPP discharge area than at that of the KNPP, although the values at both areas were comparable to previous studies in coastal areas of eastern Korea.

  • This study was carried out to investigate the feasibility of OTEC(Ocean Thermal Energy Conversion) operation, in the East Sea of Korea. Accumulated cruise data of NFRDI (National Fisheries Research and Development Institute) over the period 1966~1995 were used to locate appropriate spot by season as well as by latitude which would show the difference at least $15^{\circ}C$ or more between the surface layer and each depth of 50, 100, 150, 200, 250, 300, 400 and 500m. Our results showed that the coastal areas of Pohang city met the requirement of more than $20^{\circ}C$ difference for OTEC plant from August to October. In contrast, in case that $15^{\circ}C$ would be possible thermal difference to operate OTEC plant, most coastal areas in the East Sea including Pohang from June to December are potential candidates for this future energy source. Therefore, we present in this paper the first option to locate the best place for OTEC plant operation using Geographical Information System (GIS), which is currently used for multi-dimensional space analysis.

  • 서해 연안에 위치한 임해발전소는 지형의 특성상 천해역으로 냉각수를 방출하는데 현재까지는 시공성과 유지관리측면에서 심층방류보다 유리한 표층방류를 대부분 택하고 있다. 본 연구에서는 점차 그 중요도가 증대되는 연안환경 보호측면에서 표층방류된 냉각수의 확산거동을 심도있는 실측을 통하여 살펴보고, 이러한 표층 부력?의 거동을 전문가 해석 기법을 응용한 특성길이 혼합모형인 CORMIX3를 이용한 결과와 비교한다. (중략)
