본 발명은 원자력추진 컨테이너선의 원자로 배치·차폐 구조 및 이를 포함하는 원자력추진 컨테이너선에 관한 것으로, 더욱 상세하게는 컨테이너선에 원자력 추진 기관을 채용할 수 있고, 방사선으로부터 안전하며, 컨테이너 적재 손실을 최소화할 수 있는 원자력추진 컨테이너선의 원자로 배치·차폐 구조 및 이를 포함하는 원자력추진 컨테이너선에 관한 것이다.The present invention relates to a reactor arrangement and shielding structure of a nuclear propulsion container ship, and more particularly, to a nuclear propulsion container ship including a nuclear propulsion container ship, more particularly, to a nuclear propulsion vessel capable of employing a nuclear propulsion engine, Nuclear reactor propulsion vessel, nuclear reactor propulsion vessel, and nuclear reactor propulsion vessel.

지금까지 컨테이너선과 같은 상선에는 벙커 C유 등의 중유(HFO)(또는 MDO)를 연료로 사용하는 추진 엔진이 사용되었으나, 최근 유가 상승 등의 영향으로 중유보다 값이 훨씬 싸면서도 청정한 에너지원인 액화연료가스, 예를 들어 LNG(또는 LPG, CNG, DME)에 대한 관심이 증대되고 있다.Until now, propulsion engines using heavy oil (HFO) (or MDO) such as Bunker C oil have been used for commercial vessels such as container ships. However, recently, due to the rise in oil prices, liquefied fuel Interest in gas, for example, LNG (or LPG, CNG, DME) is increasing.

또한, LNG는 여름철의 가격이 겨울철에 비해 50%정도로 저렴하므로, 값이 싼 여름철에 LNG를 사서 저장할 수도 있어, 가격 면에서 매우 유리한 에너지원이 된다.In addition, since the price of LNG in summer is about 50% lower than that in winter, LNG can be bought and stored in a low price summer, which is a very favorable energy source in terms of price.

액화 연료가스를 연료로 사용하여 추진 동력을 얻을 수 있는 선박용 엔진으로는 예를 들어, ME-GI(Man B&W 사의 Gas Injection 엔진)와 같은 고압가스 분사엔진이 있다.As a marine engine capable of obtaining propulsion power using liquefied fuel gas as a fuel, there is a high pressure gas injection engine such as ME-GI (Gas Injection Engine of Man B & W).

이러한 액화연료가스 추진 엔진을 컨테이너 운반선에 적용하는 기술은 대한민국 공개특허공보 10-2011-0046947(2011.05.06)에 제안되어 있다.A technique for applying such a liquefied fuel gas propulsion engine to a container carrier is proposed in Korean Patent Publication No. 10-2011-0046947 (May 05, 2011).

도 1은 일반적인 컨테이너선의 펀넬과 선실 그리고 연료탱크의 배치 관계를 개략적으로 도시한 구성도이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a layout relationship between a funnel, a cabin, and a fuel tank in a general container line.

도 1을 참조하면, 일반적인 컨테이너선은 펀넬(funnel)과 선실이 분리된 구조로 구성되고, 선실의 하부에 연료탱크가 배치된다. 선체의 길이방향으로는 12m의 베이(bay)가 다수 배치된다.Referring to FIG. 1, a general container line has a structure in which a funnel and a cabin are separated from each other, and a fuel tank is disposed below the cabin. A plurality of bays of 12 m are arranged in the longitudinal direction of the hull.

그러나, 이러한 액화연료가스를 추진 엔진으로 이용하는 경우에도 연료유 가격 상승과 환경규제 강화에 따른 제약이 있을 뿐만 아니라, 액화연료가스를 연료로 사용함으로써 관련 장비들이 매우 복잡해지는 문제점이 있다.However, even when such a liquefied fuel gas is used as a propulsion engine, there is a restriction due to an increase in fuel oil price and strengthening of environmental regulations, and the use of liquefied fuel gas as a fuel has a problem that related equipment becomes very complicated.

한편, 원자력을 추진 동력으로 하는 선박은 기존에 군함 및 쇄빙선 등 특수 목적을 위한 선박에 이용되었고, 이들 선박은 원자로의 배치 및 차폐구조에 대한 제약 조건 없이 대부분 선박의 중앙부에 원자로를 배치하였다.On the other hand, ships powered by nuclear power have been used in ships for special purposes such as naval vessels and icebreakers, and these vessels have placed nuclear reactors in the center of most ships without restrictions on the arrangement and shielding of the reactor.

그러나 컨테이너선에 원자력 추진을 도입하는 경우, 기존 컨테이너선 대비 컨테이너 적재 손실량을 최소화해야 하고, 컨테이너선의 구조상 길이방향으로 약 12m인 베이(bay) 구조 내에 원자로 및 비오피(BOP)를 배치해야 하는 제약으로 이에 대한 연구 개발이 필요한 실정이다.However, when introducing nuclear power to containerships, it is necessary to minimize the amount of container loading loss compared to conventional container ships, and to limit the number of reactor And research and development is needed.
