Moving Cargo for NPPs: A Complex Task

Transporting heavy and oversized cargo for a nuclear power plant, or NPP, is a “complex and challenging task”, said Valdi Pincin, head of Comark’s project department.

“The unique safety and regulatory requirements of nuclear power plants set them apart from other industrial projects, such as oil and gas or power, and require a higher level of attention and expertise from logistics and transportation teams,” Pincin said.

“The units are very heavy, and most of the time cannot be dismantled into smaller pieces, bringing total dimensions on the very high side. Transporting nuclear fuel assemblies and other sensitive components also demands strict security protocols, which can involve extensive background checks, vehicle inspections and sometimes even the use of armed guards.”

Pincin outlined some of the main components required for an NPP:

• Reactor components – Includes the reactor vessel, steam generators, pressurizers and control rod drive mechanisms – crucial for the functioning of the plant.

• Turbine components – Includes the turbine rotor, generator rotor, condenser and other auxiliary units used for power generation.

• Cooling system components – Includes large heat exchangers, cooling towers and pumps for cooling the reactor and the steam condensers.

• Fuel assemblies – NPPs need a steady supply of nuclear fuel in the form of fuel assemblies, which need to be transported to site.

• Heavy machinery – NPPs require a range of heavy machinery used to build the facility, such as cranes, excavators and bulldozers.

• Building materials – Installing an NPP requires a range of building materials, such as steel, concrete and rebar.
