ASI: The Ideal Choice for

Commercial Diving & Robotic Solutions for the Nuclear Industry

Nuclear environments are among the world’s most high-risk and hazardous spaces for inspection and intervention tasks that demand high-reliability and deployment-confident expertise and technology. 

ASI group offers a range of underwater services that cater to the unique challenges of nuclear facilities. We are qualified and experienced to work in irradiated underwater environments and operate under strict Quality Control/Assurance guidelines. Our highly experienced team of commercial divers, ROV pilots, hydrographers, engineers, and technicians are committed to ASI’s radiation safety principle -ALARA (As Low As Reasonably Achievable) and can complete underwater inspections, maintenance, and repair projects safely and efficiently. Commercial-Diving-&-Robotic-Solutions-for-the-Nuclear-IndustryASI contributes to the safe and reliable operation of nuclear power plants by providing the services necessary for their continued operation and maintenance. Our Remotely Operated Vehicles can inspect long tunnels in a short amount of time due to our long-distance capabilities. 

ASI specialises in underwater irradiated environment diving for inspection, maintenance, and repair in areas including:

  • Primary and Secondary Spent Fuel Bays,
  • Fuel Transfer Bays,
  • Fuel Handling Systems,
  • Vacuum Building, Emergency Water Storage Tanks, and
  • Foreign Material Exclusion (FME) for all of the above. 

ASI & Nuclear Energy Inspection Solution

Energy production facilities that use nuclear reactors have numerous components that can be inspected using ROVs. These structures are either built on water or directly used water to generate energy. Before discovering how an ROV can be helpful in nuclear plants, it is vital to understand how the nuclear facility operates and the main components.ASI-&-Nuclear-Energy-Inspection-SolutionNuclear energy plants, like coal-fired plants, produce electricity by spinning turbines that are connected to a generator. The primary difference here is that instead of using coal to heat and convert the input water to steam, it is sent via a nuclear reactor vessel. When steam travels through the turbines, the blades rotate, causing the generator to create electricity. Like in coal plants, this steam is again drawn into a condenser. To prepare the steam by cooling, it needs to run through the process again. Then gallons of cold water is brought in from a nearby source.

So, where does ASI come in?

These are the fundamentals of how energy-producing plants operate. Now is the time to look at how ASI Group can help with nuclear energy production.

To keep things running properly, many of these facilities rely on water flow and tanks. Inspections of the cooling system’s intakes, outputs, and condensers are required to offset any structural damage produced by wear and tear over time.So-where-does-ASI-come-inIt’s possible that a plant component isn’t working properly at any given time. This might be due to a blocked or clogged intake or outflow, a malfunctioning condenser, or a blockage in the tubes connecting the various components. Because of the huge amount of heat created and going through the remainder of the system, emptying the tanks and tubes of water is frequently not an option.

For urgent inspections and repairs, an alternative is required. ROVs from ASI offers the perfect solution as divers are not a viable alternative for inspections due to extremely high temperatures, restricted places, and harmful radiation levels in nuclear facilities.
