Japanese Architectural Standard Specification “JASS 5 N Reinforced Concrete Work at Nuclear Power Plants” Published by Architectural Institute of Japan

“Rules on Concrete Containment Vessels for Nuclear Power Plants” was first published in 2003. It was revised in 2011 and the latest Edition was published in 2015. Endorsement of this Code is expected in the very near future. There are two types of reactor containments: steel containment vessels (hereinafter referred to as “SCV”) and concrete containment vessels (hereinafter referred to as “CCV”). The former is addressed by Rules on Design and Construction for Nuclear Power Plants, and the latter by Rules on Concrete Containment Vessels for Nuclear Power Plants, including Reinforced Concrete Containment Vessel (hereinafter referred to as “RCCV”), Pre-stressed Concrete Containment Vessel (hereinafter referred to as “PCCV”), and hybrid containment vessels which are required further safety and reliability.

Public Concerns

Nowadays, the safety of nuclear power plants is of increasing interest and importance. The main reasons for increased safety concerns are the recent major nuclear accident in Fukushima in 2011 and the overall tendency of environment protection. One of the possible ways of increasing the safety of nuclear power plants is the underground placement of all potentially dangerous systems under ground as the overlying soil or rock layer would act as a "earth" containment which would reduce the probability of ground level release following primary and secondary containment failure. Moreover, partial or total underground placement of nuclear power plant would reduce its visibility, and thus, public concerns would also be reduced. However, many design, operational, and economic disadvantages are linked with the underground placement of nuclear power plants. The aim of this paper is to provide state-of-the-art review of existing underground nuclear reactors, conceptual designs of underground nuclear reactors, and related literature, which can later be used for the design of a underground reinforced concrete containment building.

Reinforced Concrete Wall

The steel plate-concrete structure, with its advantages of modular construction, good seismic capacity, and strong impact resistance, has been gradually replacing the reinforced concrete structure in the containment vessel and internal workshop structure of nuclear power plants in recent years. In this study, the out-of-plane single-point loading test and parametric finite element simulation analysis were conducted on five steel plate-concrete wall slab specimens with different stud spacings, shear span ratios, and steel contents. Results showed that the steel plate-concrete wall slab under the out-of-plane load had the same failure mode as that of an ordinary reinforced concrete wall. The out-of-plane shear capacity of the steel plate-concrete wall slab increased significantly in the case of numerous studs. With the increase in shear span ratio, steel plate-concrete members suffered a bending failure. When the steel content was low, they had diagonal tension failure, such as a rare-reinforced concrete wall. The out-of-plane bending and shear mechanism of the steel plate-concrete shear wall was studied theoretically, and the calculation formulas of the bending and shearing capacities were derived.
