Description

미드룹 적용된 오일샌드 채굴용 경수형 원자로Light water reactor for oil sand mining with mid-loop application
본 발명은 미드룹 적용된 오일샌드 채굴용 경수형 원자로에 대한 발명이다. 본 연구는 2023년도 과학기술정보통신부(정부)의 재원으로 한국연구재단의 지원을 받아 한국원자력연구원에서 수행된 SMART혁신기술개발사업(R＆D)사업의 혁신 SMART 계통 요소기술 개발 (과제고유번호: 1711154717, 과제번호: 2020M2D7A1079178)과 관련된다.The present invention relates to a light water reactor for oil sand mining applied to a midloop. This study was conducted at the Korea Atomic Energy Research Institute with the support of the National Research Foundation of Korea with funding from the Ministry of Science and ICT (government) in 2023 to develop innovative SMART system element technology of the SMART Innovation Technology Development (R&D) project (Project identification number: 1711154717) , task number: 2020M2D7A1079178).
일반적으로, 오일샌드(oilsand)는 모래(sand)와 역청(bitumen, 천연탄화수소 화합물의 총칭), 점토(clay), 물(water) 등의 혼합물을 일컫는다. 오일샌드 내에 원유가 포함되어 있다는 사실이 밝혀지면서, 최근 오일샌드에서 원유를 추출하는 기술이 발전되고 있다. 이러한 오일샌드가 많이 발견되는 캐나다 등지에서 여러 오일샌드 광구들이 개발되고 있다.Generally, oil sand refers to a mixture of sand, bitumen (a general term for natural hydrocarbon compounds), clay, and water. As it has been revealed that oil sands contain crude oil, technology for extracting crude oil from oil sands has recently been developed. Several oil sand fields are being developed in places such as Canada, where many of these oil sands are found.
오일샌드를 채굴하는 기존의 여러 방법 중 일부인 CSS(cyclic steam stimulation) 방법 및 SAGD(steam assisted gravity drainage)방법은 250도 이상 300도 이하의 고온 및 고압의 증기를 땅속으로 주입하여 점도가 높은 상태의 오일샌드를 녹여 배관 수송이 가능할 정도로 점도를 낮춘 뒤 지표 밖으로 뽑아내는 방법이다. CSS 방법은 하나의 구멍을 통해 증기를 오랫동안 주입하며 오일샌드가 녹기를 기다렸다가 같은 구멍으로 다시 오일샌드를 빨아들여 채굴하는 방식이고, SAGD 방법은 2개의 구멍 중 하나의 구멍으로 증기를 계속 주입하고 다른 하나의 구멍으로 오일샌드를 연속적으로 채굴하는 방식이다.The CSS (cyclic steam stimulation) method and SAGD (steam assisted gravity drainage) method, which are some of the existing methods of mining oil sands, inject high temperature and high pressure steam of 250 to 300 degrees into the ground to create high viscosity oil. This is a method of melting the oil sand to lower its viscosity enough to allow pipe transportation and then extracting it out of the surface. The CSS method is to inject steam through one hole for a long time, wait for the oil sand to melt, and then suck the oil sand back into the same hole to mine it. The SAGD method is to continuously inject steam through one of the two holes and extract the oil sand from the other hole. This is a method of continuously mining oil sands through a single hole.
이와 같은 CSS 방법이나 SAGD 방법을 통해 오일샌드를 채굴하기 위해서는, 250도 이상 300도 이하의 고온 및 고압의 증기가 필요하다. 기존에는 이 증기를 생산하기 위해 화력보일러를 이용해 왔다. 그러나 화력보일러는 이산화탄소 배출이 많아 여러 환경문제를 일으키고 있고, 최근 “탄소세(carbon tax)”가 증가하는 추세여서 경제성이 약화되는 문제점을 보이고 있다. In order to mine oil sands using the CSS method or SAGD method, high temperature and high pressure steam of 250 degrees to 300 degrees is required. Previously, thermal boilers were used to produce this steam. However, thermal power boilers are causing various environmental problems due to their high carbon dioxide emissions, and the recent increase in “carbon tax” is showing the problem of weakening economic feasibility.
따라서, 이산화탄소 배출이 적은 에너지를 사용하면서도, 효과적으로 증기를 생산하여 오일샌드를 채굴하기 위하여 오일샌드 채굴 시스템에 경수형 원자로를 적용하는 기술이 개발되었다.Therefore, in order to mine oil sands by effectively producing steam while using energy with low carbon dioxide emissions, a technology for applying a light water reactor to an oil sands mining system has been developed.
이러한 경수형 원자로는 원자로를 포함하는 핵증기공급계통(NSSS, nuclear steam supply system)에서 증기를 생성한 뒤, 이 증기를 동력변환계통으로 이송하여 발전한다. 경수형 원자로가 오일샌드 채굴 시스템에 적용됨으로써 경수형 원자로에서 생성된 증기를 지반에 주입할 수 있게 되었으나, 지반에서 회수되는 물의 수질관리가 어려운 문제점이 발생하고, 경수형 원자로와 지반 사이에 방사능을 막아줄 방벽이 존재하지 않아 방사능 안전관점에서 위험하다는 문제점이 발생한다.These light water reactors generate steam in a nuclear steam supply system (NSSS) including the nuclear reactor and then transfer this steam to the power conversion system to generate power. As light water reactors were applied to the oil sand mining system, it became possible to inject steam generated from light water reactors into the ground. However, problems arose in managing the quality of water recovered from the ground, and radioactivity was created between the light water reactors and the ground. Since there is no barrier to block it, there is a problem that it is dangerous from a radiation safety perspective.
따라서, 오일샌드 채굴 시스템에 제공되는 고온 및 고압의 증기를 제공하면서도 수질 관리가 용이하고, 방사능 안전관점에서도 유리한 경수형 원자로에 대한 필요성이 증대되고 있다.Accordingly, there is an increasing need for a light water reactor that provides high temperature and high pressure steam for the oil sand mining system, but is also easy to manage water quality and is advantageous from a radiation safety perspective.
본 발명의 일 실시예들은 상기와 같은 배경에 착안하여 발명된 것으로서, 오일샌드 채굴을 위하여 필요한 고온 및 고압의 증기를 생산하면서도, 이산화탄소 배출을 최소화할 수 있는 구조를 가진 경수형 원자로를 제공하고자 한다.One embodiment of the present invention was invented with the above background in mind, and aims to provide a light water reactor with a structure that can minimize carbon dioxide emissions while producing high temperature and high pressure steam necessary for oil sand mining. .

Therefore, it is intended to provide a light water reactor that can produce steam with a pressure that varies depending on the progress of oil sands mining.
또한, 원자로모듈에서 공급된 증기의 압력과 미드룹 증기발생기에서 응축되는 증기의 압력의 차이를 사용자가 원하는 만큼 변화시킬 수 있는 경수형 원자로를 제공하고자 한다.In addition, it is intended to provide a light water reactor that can change the difference between the pressure of steam supplied from the nuclear reactor module and the pressure of steam condensed in the mid-loop steam generator as desired by the user.
또한, 원자로모듈을 유동하는 작동 유체와 지반을 유동하는 작동 유체가 물리적으로 분리되어 유동하도록 함으로써, 수질 관리가 용이한 경수형 원자로를 제공하고자 한다.In addition, it is intended to provide a light water reactor in which water quality is easy to manage by allowing the working fluid flowing through the reactor module and the working fluid flowing through the ground to flow in a physical separation manner.
또한, 지반에 직접적으로 원자로모듈에서 방출되는 방사성 물질이 도달하지 않도록 방벽을 구성함으로써, 방사능 안전관점에서 유리한 경수형 원자로를 제공하고자 한다.In addition, it is intended to provide a light water reactor that is advantageous from a radiation safety perspective by constructing a barrier to prevent radioactive materials emitted from the reactor module from reaching the ground directly.
또한, 원자력모듈에서 발생되는 열을 전력 발전 터빈부와 오일샌드 채굴 시스템에 동시에 사용되도록 하면서도, 두 시스템의 에너지 비율을 조절함으로써, 상황(오일샌드용 증기 사용 수요 또는 전력 수요)에 맞게 열을 제공할 수 있는 경수형 원자로를 제공하고자 한다.In addition, the heat generated from the nuclear module is used simultaneously for the power generation turbine unit and the oil sand mining system, while adjusting the energy ratio of the two systems to provide heat according to the situation (demand for steam use for oil sands or power demand). We would like to provide a light water reactor that can

이하, 도면을 참조하여 본 발명의 제1 실시예에 따른 미드룹 적용된 오일샌드 채굴용 경수형 원자로(1)의 구체적인 구성에 대하여 설명한다. Hereinafter, with reference to the drawings, the specific configuration of the light water reactor 1 for oil sand mining applied to the midloop according to the first embodiment of the present invention will be described.
도 1 및 도 2를 참조하면, 제1 실시예에서 오일샌드 채굴용 경수형 원자로(1)는 원자로모듈에서 발생한 열을 이용하여 별도로 증기를 생성할 수 있는 미드룹 증기발생기를 원자로모듈에 연결함으로써, 오일샌드를 채굴할 수 있다. 이러한 오일샌드 채굴용 경수형 원자로(1)는 원자로모듈(10), 터빈부(20), 미드룹 증기발생기(30), 처리부(40), 연결부(50), 펌프부(60), 분리기(70), 가압기(80) 및 히터부(90)를 포함할 수 있다.Referring to FIGS. 1 and 2, in the first embodiment, the light water reactor 1 for oil sand mining is connected to the reactor module with a midloop steam generator capable of separately generating steam using heat generated from the reactor module. , oil sands can be mined. This light water reactor (1) for oil sand mining includes a reactor module (10), a turbine unit (20), a mid-loop steam generator (30), a processing unit (40), a connection unit (50), a pump unit (60), and a separator ( 70), a pressurizer 80, and a heater unit 90.
원자로모듈(10)은 노심의 핵반응을 통해 발생된 열을 이용하여 작동 유체를 가열할 수 있다. 이러한 원자로모듈(10)은 발생된 열의 적어도 일부를 외부로 공급할 수 있다. 예를 들어, 원자로모듈(10)은 250도 이상 310도 이하의 고온의 작동 유체를 외부로 배출할 수 있다. 이러한 원자로모듈(10)은 핵분열에 의해서 발생되는 열을 이용하여 작동 유체를 가열시킬 수 있다. 또한, 원자로모듈(10)은 사고시, 냉각수 등의 냉각재가 자연순환됨으로써, 후술할 노심(11)이 피동적으로 냉각될 수 있다. 이러한 원자로모듈(10)에서 배출되는 작동 유체는 물 또는 오일류일 수 있다. 원자로모듈(10)의 일측은 작동 유체 어느 일부가 터빈부(20)에 연통되도록 터빈부(20)에 연결될 수 있다. 또한, 원자로모듈(10)의 타측은 미드룹 증기발생기(30)에 연결될 수 있다. 원자로모듈(10)의 작동 유체 중 터빈부(20)으로 유동하는 작동 유체는 터빈 유체로 명명될 수 있으며, 이러한 터빈 유체는 원자로모듈(10)과 미드룹 증기발생기(30) 사이에서 유동하는 작동 유체와 독립적으로 유동될 수 있다. 다시 말해, 원자로모듈(10)은 터빈유체와 작동 유체가 서로 혼합되지 않게 유동하도록 구성될 수 있다. 원자로모듈(10)은 핵증기공급계통(NSSS, nuclear steam supply system)일 수 있다. 이러한 원자로모듈(10)은 노심(11), 열교환기(12) 및 원자로용기(13)를 포함할 수 있다.The nuclear reactor module 10 can heat the working fluid using heat generated through a nuclear reaction in the reactor core. This nuclear reactor module 10 can supply at least a portion of the generated heat to the outside. For example, the nuclear reactor module 10 may discharge high temperature working fluid of 250 degrees to 310 degrees to the outside. This nuclear reactor module 10 can heat the working fluid using heat generated by nuclear fission. In addition, in the event of an accident in the nuclear reactor module 10, the reactor core 11, which will be described later, can be passively cooled by natural circulation of coolant such as coolant. The working fluid discharged from the nuclear reactor module 10 may be water or oil. One side of the nuclear reactor module 10 may be connected to the turbine unit 20 so that a portion of the working fluid communicates with the turbine unit 20. Additionally, the other side of the reactor module 10 may be connected to the midloop steam generator 30. Among the working fluids of the nuclear reactor module 10, the working fluid flowing into the turbine unit 20 may be referred to as turbine fluid, and this turbine fluid flows between the nuclear reactor module 10 and the mid-loop steam generator 30. It can flow independently of the fluid. In other words, the nuclear reactor module 10 may be configured so that the turbine fluid and the working fluid flow without mixing with each other. The nuclear reactor module 10 may be a nuclear steam supply system (NSSS). This nuclear reactor module 10 may include a reactor core 11, a heat exchanger 12, and a reactor vessel 13.
노심(11)에서는 핵분열이 발생될 수 있다. 이러한 노심(11)에는 우라늄 등 방사성 물질을 포함하는 핵연료(미도시)가 배치되어 핵분열이 발생될 수 있다. 또한, 노심(11)은 원자로용기(13)의 내부에 배치될 수 있다.Nuclear fission may occur in the reactor core 11. Nuclear fuel (not shown) containing radioactive materials such as uranium is placed in the core 11, so nuclear fission may occur. Additionally, the reactor core 11 may be placed inside the reactor vessel 13.
열교환기(12)는 노심(11)의 열에 의해 증기상태로 변화되어 원자로용기(13)로부터 배출된 냉각재를 응축시킬 수 있다. 이러한 열교환기(12)는 원자로용기(13)의 외측에 배치될 수 있다.The heat exchanger 12 is converted into a vapor state by the heat of the reactor core 11 and can condense the coolant discharged from the reactor vessel 13. This heat exchanger 12 may be placed outside the reactor vessel 13.

For example, in the early stages of oil sand mining, high-pressure steam of approximately 10 Mpa or more is required, in the mid-stage, relatively medium-pressure steam of approximately 6 to 8 Mpa is required, and in the final stage, low-pressure steam of approximately 4 Mpa or less is required. is needed.

After being recovered in the N-th mid-loop steam generator (30), the oil sand side fluid can change its state to saturated steam in the N-th mid-loop steam generator (30). Therefore, the saturation pressure of the steam of the N-th mid-loop steam generator 30 may be higher than the saturation pressure of the steam of the N+1-th mid-loop steam generator 30. In addition, the second recovery pump 622 provides different rotational speeds to apply different pressures to the oil sand side fluid, so that the steam pressure provided by the plurality of midloop steam generators 30 is provided differently. .

It can provide a barrier that prevents damage.

The water quality management measures used in can be used as is without any design changes. There is no change in the design of the light water reactor to manage the water quality of the working fluid, so there is no additional cost.
또한, 원자로모듈(10)에서 발생하는 고온 및 고압의 작동 유체가 터빈부에도 동시에 제공될 수 있도록 구성됨으로써, 사용자의 필요에 따라 전력 발전과 오일 분리의 비율을 조절하여 사용할 수 있는 효과가 있다.In addition, the high-temperature and high-pressure working fluid generated in the reactor module 10 is configured to be simultaneously provided to the turbine unit, so that the ratio of power generation and oil separation can be adjusted according to the user's needs.
