Peikko Nuclear Power Plant Projects with Safety Requirements and Traceability

Peikko offers longstanding NPP expertise and products that improve the safety of your project. With constant evaluation and development of our own processes, we are able to build projects with a higher level of safety and quality compared to the standard level in the building industry. Peikko experts offer reliable customer service and excellent cooperation.

Safety is at the core of our NPP expertise, and we are committed to operating in a sustainable manner, including the delivery of high-quality products and services in line with the principles of Nuclear Safety Culture. Furthermore, our management, organisation, and processes are built in accordance with Nuclear Safety principles. With full transparency of all our process phases, and with all work being organised based on international nuclear standards, every single product is completely traceable. We always provide you with all the documentation required for your project.

Solid Reputation and Experience in the Industry

Peikko is a well-established supplier of steel fastening products for nuclear power plant projects, with a solid reputation in the industry and an excellent track record. In addition to several completed and ongoing projects around the world, we are currently involved in an EU funded development project, together with EDF and 6 other organisations, to develop a new type of Steel Concrete (SC) structure for concrete walls. We have also been involved in projects to close power plants in Lithuania and Germany, and in the construction of permanent nuclear-waste repositories in Finland.

Peikko Solutions for your NPP Project Requirements

Peikko offers industrial and cost-effective manufacturing of embedded components so that your NPP project is safer, faster and more efficient.

WELDA® Anchor Plates


WELDA® Anchor Plates are CE marked and quite versatile for transferring loads to concrete from other structures using a welded connection. Stud-headed anchors are welded onto the plate and optimised for easy installation onto the reinforcement plate. Anchors are available in three different lengths so that they sit evenly and do not require additional reinforcement.

All WELDA® Anchor Plates are CE marked based on ETA-16/0430 standards and fulfil all the requirements for anchor plates. Peikko is the only company in the industry that can deliver CE marked anchor plates based on ETA standards.

Anchor Bolts

Anchor bolts are used in many different applications such as in machine foundations and for precast structures. Peikko provides high-strength anchor bolts and column shoes for any type of anchoring, including NPP projects. What’s more, our ECO galvanizing offers a cost-effective solution to protect anchor bolt threads against corrosion.

PSB® Shear Reinforcement

NPP concrete structures are heavily reinforced. The ETA approved PSB® shear reinforcement systems can replace the traditional stirrups. These are much easier to install and provide a higher shear capacity and are an efficient solution for impact loads.

PSB® Punching Reinforcement

FATBAR® Post-Tensioned Anchor

The ETA approved FATBAR® System for demanding engineering applications is able to sustain the ETAG 13 fatigue load tests with ease. The FATBAR®s are post-tensioned against high dynamic stress, protecting foundations from cracking even in harsh conditions.

MODIX® Rebar Couplers

The MODIX® Rebar Coupler is designed to be the safest and most flexible rebar splicing system. With the unique visual inspection system, it is safe and easy to verify that all connections are closed and capable of handling the required loads. The system guarantees high flexibility and good quality.

EU funded research project SCHEDULE

Peikko is currently involved in an EU funded development project, together with EDF and 6 other organizations, to develop a new type of Steel Concrete (SC) structure for concrete walls. 

New construction method based on double skin steel concrete composite (SC) structure is tested in research project called SCHEDULE.

The project is currently on construction phase. Peikko Lithuania manufactured all steel components to this project with the total volume of 400 tons. Peikko was also responsible for workshop drawings of the components.

New Steel Concrete, SC, construction method is aiming to reduce construction schedule by 50% compared to traditional cast-in situ reinforced concrete, RC, in heavy reinforced structures, like nuclear power plants. SC method provides 20% reduction in section thickness compared with RC. In addition, there is no need for conventional bar reinforcement or temporary formwork at all. 

The project collects practical experiences and real cost data by constructing a pilot building using this new SC construction method. The pilot building will be a geometrically exact replica of the EDF’s diesel generator building for nuclear power plants.  Pilot building will be constructed in EDF Lab in Renardieres, France by construction company Bouygues.

Pilot project results will be compared to data collected from EDF’s diesel generator building projects made with traditional, RC, method. Practical solutions for SC construction methods are not limited to nuclear power plant solutions. It can be used in many other reinforced concrete constructions - high rice buildings, bridges, protection walls, etc.
