Radioactive Waste Handling Equipment

Remote handling equipment for radioactive waste is critical for minimizing radiation exposure for personnel at nuclear power plants. Our Bridge-Transported Dual-Arm Servo-Manipulator (BDSM) system consists of master manipulators, bridge transporter, slave manipulators, and control system. It features a cable driven arm system, trolley system, and telescopic tube. The control command provides force and visual feedback for the operator for precise operation. The technology behind our BDSM system was developed by the Korea Atomic Energy Research Institute (KAERI) and acquired through a technology transfer.

Geothermal Power Generation | Turbines

Geothermal power plants is clean and renewable, unlike conventional fossil fuel energy by using steam produced from reservoirs of hot water found a few miles or more below the Earth’s surface to produce electricity. The steam rotates a turbine that activates a generator, which produces electricity. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle.

 

Our experience include supplying vaporizer, preheater, pressure vessel, air cooler, recuperator, condensor, separator, accumulators as well as piping spools and rotary equipment.

 

Over the years, our static equipment has been supplied to projects in Canada, USA, Kenya, Turkey, New Zealand, and Russia.
