Description
Over the past few years, there has been considerable interest in the use of modular steel-concrete composite structures for the construction of buildings for nuclear power plant, especially out of Europe. Indeed, the use of steel concrete structures is known to shorten the construction duration, as it enables to reduce the number of tasks such as erecting the concrete formwork and installing reinforcements. There is also a major improvement regarding the challenges for equipment anchoring.
AFCEN, which is an international association of companies from the nuclear energy sector, develop and adapt advanced rules to fit the specificities in relation with safety of this industry. A working group (WOG8 ) dedicated to Steel Concrete Structures has been created to write dedicated chapters in the Code RCC-CW
(Rules for Design and Construction PWR Nuclear Civil Work).
EDF’s experience regarding the use of the Steel Concrete Structures through two European projects (SCIENCE & SCHEDULE) has allowed to draw some fundamental design and construction principles of standard sections and connections of steel concrete modules. In 2021, AFCEN has mandated EDF to produce a report gathering the “Technical Status on the Design and Construction of Steel Concrete Structures” (PTAN) to be used as a basis for the implementation of new chapters dedicated to Steel Concrete Structures in the next revision of the RCC-CW (expected to be issued on 2025).
The Codification of the steel concrete technology strengthen the opportunity for future projects such as NUWARD SMR to use it, especially in safety classified structures.
This paper aims to present the main outcome of the European codification of SCS Structures.
