The construction and testing of a model of a prestressed concrete containment structure is described. The test structure consisted of a reinforced concrete base, cylindrical wall, ring beam and dome built of prestressed concrete with construction details patterned after the Canadian CANDU reactor containment. The overall height above the base was 12 ft‐6 in. (3,810 mm), and the outer diameter was 10 ft‐6 in. (3,200 mm). Internal pressure was obtained using water, and leakage was prevented by… 
Ultimate internal pressure of Prestressed Concrete Containment Vessel analyzed by an integral constitutive model
This work focuses on the safety margin of Prestressed Concrete Containment Vessel (PCCV) under internal pressure beyond the design load up to its ultimate strength. Due to the complicated
Failure mechanism of a prestressed concrete containment vessel in nuclear power plant subjected to accident internal pressure
Abstract The leakage of the internal gas could cause structural expansion and cracking of the containment structures in nuclear power plant (NPP). Predicting the ultimate internal pressure resistant
Modular construction mechanics of a European pressurized reactor steel containment liner
A European pressurized reactor (EPR) steel containment liner structure is comprised of the cylinder part and the dome part. An introduction of the steel liner structure is presented, followed by
Study on mechanical behavior of containment in nuclear power plant during prestressing construction
Taking a third generation nuclear power plant as the research background, a refined model of a prestressed concrete containment which consisted of 270 complex spatial prestressed tendons was accurately established, using FE software ABAQUS to simulate the tensioning process of tendons.
Analytical evaluation of the dome-cylinder interface of nuclear concrete containment subjected to internal pressure and thermal load
Abstract Nuclear concrete containment structures serve as the main line of defense to prevent escape of radioactive material during catastrophic events including the loss of coolant accident (LOCA),
Numerical models for prestressing tendons in containment structures
Abstract Two modified stress–strain relations for bonded and unbonded internal tendons are proposed. The proposed relations can simulate the post-cracking behavior and tension stiffening effect in
Nonlinear analysis of pre-stressed concrete containment vessel (PCCV) using the damage plasticity model
Abstract This paper describes the nonlinear analyses of a 1:4 scale model of a pre-stressed concrete containment vessel (PCCV). The analyses are performed under pressure and high temperature effects
An Approach for Performance-Based Capacity Assessment of Prestressed Concrete Containment Vessels for Internal Accidents Application to VVER 1000 Containment Vessel
A direct procedure is proposed for capacity assessment of prestressed concrete containment structures subjected to internal accident loads. The assessment procedure is based on graphical comparison
Fragility analysis of prestressed concrete containment under severe accident condition
Results indicate that functional failure of containment is dominated by the location of equipment hatch, and sensitivity analysis of the input random variables reveale that modulus of elasticity of prestressed tendon make most contribution to the pressure capacity of the containment.
