What Is Nuclear Power Plant Transport?

Short Answer — Nuclear Power Plant Transportation

Nuclear power plant transportation is the quality-assured, traceable and documented movement of the reactor equipment, turbines, piping, cables and construction materials needed to build and commission a nuclear power plant, from the manufacturer to the plant site. Most of the equipment transported is not radioactive; the real challenges are weight, sensitivity and documentation requirements.

Which loads does nuclear power plant logistics cover?

The cargo going to the site for a VVER-1200 unit ranges widely, from giant single-piece equipment to small spare parts. The logistics plan is usually built around the following groups:

Nuclear island: reactor pressure vessel (330–350 tonnes at Akkuyu), four steam generators (340–355 tonnes each), main circulation pumps, pressuriser, core catcher.
Conventional island: turbine, generator stator, condenser, power transformers.
Auxiliary systems: pipes, valves, cables, panels, measuring instruments and spare parts.
Construction materials: steel structures, rebar, prefabricated modules.

The volume is not small either: from 2019 to February 2025, 100 cargo ships reached the Eastern Cargo Terminal, Akkuyu's own pier, and more than 100,000 tonnes of cargo were unloaded.

Fresh nuclear fuel is kept outside this list; as a radioactive material, it is transported separately under the IAEA's SSR-6 regulations and the national licensing regime. The status of other equipment is explained in the entry on whether nuclear equipment is radioactive.

How does it differ from conventional project logistics?

Topic	Conventional project transport	Nuclear power plant transport
Quality requirement	Delivery without damage	Delivery without damage and preservation conditions proven by documents
Identification	Order or part number	KKS code, serial number, equipment passport
Packaging	Transport resistance	Humidity, corrosion, shock and tilt specifications
Storage	General open or covered area	Area of level A–D depending on the sensitivity of the equipment
Site entry	Standard occupational safety	Physical protection, identity and vehicle checks

The difference stems from the nuclear safety class of the equipment. If a safety-relevant part is dropped, gets wet or is unpacked without authorisation during transport, it may not be accepted for installation.

Who is responsible?

Plant owner and operator: At Akkuyu, this role belongs to Akkuyu Nuclear JSC (Akkuyu Nükleer A.Ş.); supervision of the supply chain is also the owner's responsibility.
Manufacturers: Pack the equipment according to the preservation specification and prepare its documents.
Logistics companies and customs brokers: Carry out transport, transhipment, customs clearance and delivery to site.
Regulatory body: In Türkiye, the Nuclear Regulatory Authority (Nükleer Düzenleme Kurumu, NDK). With the amendment of 2 October 2026 to the Regulation on Authorisations for Nuclear Facilities (Nükleer Tesislere İlişkin Yetkilendirmeler Yönetmeliği), the manufacture of safety-relevant equipment became subject to a permit, and conformity verification became mandatory for off-the-shelf components.

What stages does a shipment go through?

Transport plan: route, vehicle and vessel selection, KKS and document list.
Loading supervision at the factory, packaging and sensor checks.
Road or inland waterway transport from the factory to the port.
Sea transport; heavy equipment usually arrives directly at the plant's pier.
Customs clearance and road delivery to the site.
Incoming inspection and placement in the appropriate storage level.
Handover for installation and preservation until the commissioning period.

Common mistakes

Sending documents after the cargo; a missing passport leads to the material being quarantined on site.
Not comparing the KKS code on the crate with the packing list.
Not keeping a humidity record for sensitive equipment waiting in an open area at a transhipment port.

How does Voltim Global help?

Voltim Global has made more than 450 shipments from Russia to Akkuyu NPP since March 2024; most of its trips used the Tuapse–Taşucu RoRo line, and some went by road via Upper Lars–Georgia and Iran. Route details are on the Akkuyu supply logistics page; the company's ISO 28000 certificate covers supply chain security.

Frequently Asked Questions

Why does nuclear power plant equipment mostly arrive by sea?

Moving single-piece equipment of more than 300 tonnes, such as a reactor pressure vessel or steam generator, hundreds of kilometres by road is often impossible because of bridge, overpass and permit restrictions. That is why power plants are built on the coast and have their own cargo pier. The first reactor vessel for Akkuyu reached the Eastern Cargo Terminal on site directly from Volgodonsk after a sea voyage of about 3,000 km lasting 20 days.

Can any logistics company handle nuclear power plant transportation?

Legally, the carrier must hold the relevant transport authorisation documents; however, the plant owner looks for much more when selecting suppliers. The quality management system, supply chain security, document discipline, compliance with site entry rules and heavy-cargo experience are audited. The NDK regulation amendment of October 2026 also puts supply chain supervision and conformity verification for safety-relevant components in the foreground.
