Current Status

BHI has delivered more than 12units of CPP so far, and our key customers are major operators of power plant industries such as KEPCO, KHNP and Westinghouse.

Performance

CPTS Containment Post Tensioning System

CPTS is a facility that reinforces the containment building by applying compressive force to the structure through tensioning the properly arranged wires after installation of the containment building. In the event of accident, it prevents radiation and high-temperature and high-pressure steam from the RCS(Reactor Coolant System) from leaking. Also, CPTS is to protect the primary equipment of the RCS when abnormal load(earthquake, aircraft crash, etc.) occurred outside of the containment building.

Current Status

Performance

Since the cask store spent nuclear fuels that generate radiation and residual heat inside, it must always satisfy subcritical requirements, structural requirements, radiation protection requirements, radioactive material containment requirements and heat removal requirements for safety.

Current Status

BHI has signed a cooperation contract with GNS of Germany in 2019 and is working on the project.

CFVS Containment Filtered Venting System

A containment filtered venting system(CFVS) is a mitigation measure that prevents over-pressurization of the containment building during a severe accident in a nuclear power plant(NPP). The CFVS releases gas from the containment building into the environment to protect the integrity of containment structures by reducing the internal pressure.

In severe accidents, however, the gas in the containment contains large amounts of fission products from the degraded reactor core, which can greatly increase ther isk of radiation exposure to the public.T o minimize this risk, the CFVS releases the containment atmospher eto the environment through a series of radioactive material decontamination processes.

CFVS is a wet type filtration system, whereby gas mixtures such as steam, air, and fission product are discharged from the containment pass through the CFVS tank, after which a large proportion of fission products are filtered before the gas is finally vented to the environment.

Current Status

BHI has developed CFVS to prevent containment damage from severe accident.

Performance

MSR Molten Salt Reactor

Molten Salt Reactor(MSR) is one of the 4th generation Small Modular Reactor(SMR), while conventional reactors implement solid fuel mixture, primary nuclear reactor coolant and fuel of MSR are molten salt mixture(Thorium, uranium hexafluoride, zirconium and etc.).

Major Features

It is a small module nuclear power plant with an electrical output of 100~300MWe and has high safety, while the initial investment cost is low and the construction period is short. In MSR, when an accident occurs, the nuclear fuel(molten salt) in the nuclear reactor solidifies which the possibility of a serious accident is theoretically close to zero. MSR has scalability that can be used not only for power generation but also for hydrogen production, ammonia production, and seawater desalination facilities.

Current Status

SGS Steam Generation System

A system that uses heat generated from MSR to produce high-temperature steam. A system in which the high-temperature Molten Salt that has passed through the Primary Heat Exchanger travels through the heat exchanger sequentially and exchanges heat with water to produce steam.

Current Status

i-SMR Innovation-Small Modular Reactor

SMR(Small Modular Reactor) is a nuclear reactor with an electrical output of 300 MW or less that is installed easily at the site b yintegrating a nuclear reactor, steam generator, coolant pump, and pressurizer into a single container. It's manufactured as an integrated module and transported to the site directly.
Unlike conventional reactors being constructed at the nuclear power plant site simultaneously, SMR improves reliability and economic efficiency through design simplification and standardizing of the manufacturing process. Manufactured SMR modules are transported and installed on-site.
SMR has lower output than large nuclear power plants, so it is easy to adopt a safety system that uses natural physics without an external power source and has high intrinsic safety. Since the system is compact, it can dramatically reduce the amount of radioactivity leaked into the environment in case of an accident in various ways, such as an underground burial method, submerging it in a cooling tank, and using an ofshore floating structure. In addition, nuclear fuel can be used more efficiently compared to large nuclear reactors, and the infrastructure and manpower required for replenishing and transporting nuclear fuel can be minimized, thereby improving nuclear security.
BHI participated in SMR development and developed Fuel Handling System and Containment Pressure & Radioactivity Suppression System(CPRSS) Lid suitable for SMR.

Current Status

BHI participated in the development of SMART 100 SMR based on its design and experience in nuclear power plants and provided design and linkage data for the most connected and independent design facilities and CPRSS Lid required in nuclear power plants.

Deaerator

The deaerator is a device that removes non-condensable gases - dissolved oxygen and carbon dioxide in feed water, for corrosion prevention of the feed water system in the steam generation system of power plant equipment, functions the open type heat exchanged to heat water, and keeps NPSH(Net Positive Suction Head) of the feed water pump constant. There are various types; all-in-one type of heater and storage tank, 2-step spray & tray type of vertical heater - horizontal storage tank and horizontal heater - horizontal storage tank, etc.

Current Status

2-step spray & tray type of deaeration is the most reliable know-how that users can get a specific performance for a specific load range. BHI has used it for development of its major products of deaerator for years. Use of this method enables users to remove dissolved oxygen by 0.005cc/l and carbon oxide by 100%. Therefore this product has an excellent performance in corrosion prevention of system.
