Steel Concrete (SC) Wall Fabrication, Construction and InspectionMUAP-12006 (R0)1.0 INTRODUCTIONThis TeR presents the applicable codes and standards, fabrication, transportation, erection,concrete placement, construction tolerances, and inspection before, during and after fabricationand construction for SC structures. The activities presented in this document are based uponsuccessful application of SC structures in Japan, but, in general, are not mandatoryrequirements. The term SC wall is also used for SC structures. The term SC modules is used toidentify the prefabricated blocks (SC structure steel modules) used to construct the SCstructures.Due to their modular nature, the steel portion of SC structures may be shop fabricated,transported to the site, and assembled in place. The walls are completed by pouring concretebetween the steel face plates. The steel face plates act as forms for the concrete and providethe permanent exterior face of the SC structure. Tie bars and studs are welded on the innersurface of the face plate assembly and become embedded in the concrete to tie the concreteand face plate together. The base plates for the SC structure form part of prestressed concretecontainment vessel (PCCV) liner plate and are anchored to the basemat.This SC structure approach is used in the construction of containment internal structure (CIS)walls in Japanese nuclear power plants. The SC structure construction methods offerimprovement in first time quality and a reduction in rework due to fabrication and assembly inthe shop environment. This results in a significant schedule advantage when compared withconventional reinforced concrete (RC) structure construction.The structural integrity of SC structure is ensured by conservative design methods that havebeen verified by experimental approaches. Refer to TeRs MUAP-11013, MUAP-11018,MUAP-11019 and MUAP-11020 (References 1, 2, 3, and 4) for additional information on thedesign of the SC structures.This TeR establishes MHI guidance and expectations for the fabrication, transportation,erection and concrete placement of SC structures. Combined License Applicants shall preparedetailed construction and inspection documents based upon this TeR. This TeR identifies fourreference documents to be created: a SC Structure Fabrication Plan, SC Steel Transport Plan,SC Structure Construction Plan, and SC Structure Inspection Plan. These documents aredeveloped during detailed design.Mitsubishi Heavy Industries, LTD.1-1
