Overview of Piping Analysis
BWXT offers a comprehensive range of engineering capabilities focused on conducting piping and components analysis utilizing various computer codes. Piping analysis becomes crucial to validate modifications to piping systems attributed to changes in routing, supports, snubbers, or equipment within the system. Furthermore, analysis may also be necessary to authorize alterations in operating conditions such as power uprates. The scope of the impacted systems can vary from minor branch lines to the entire Reactor Coolant System, encompassing components like the reactor vessel, RC pumps, steam generators, and pressurizer.
Applications and Capabilities
BWXT possesses significant expertise in the realm of Nuclear Piping and Components design and analysis, covering ASME Section III Class 1 NB, Class 2 NC, and Class 3 ND Piping Components in adherence to ANSI/ASME B31.1 Power Piping Code. Leveraging state-of-the-art finite element software like ANSYS®, ABAQUSTM, PV Elite®, and Compress, the company excels in tackling intricate design challenges promptly. The experienced engineers can effortlessly generate and analyze 3-D piping models under varied loading conditions. Utilizing static linear/non-linear structural, thermal transient, or dynamic analysis techniques, they can ascertain loads on each component due to deadweight, thermal expansion, seismic events, and dynamic accidents. The analysis of seismic and accident events can be conducted using equivalent static, response spectrum, or time-history methods.
Nozzle/Pipe Junctures Analysis
BWXT also specializes in detailed 3-D or axisymmetric modeling of nozzle/pipe junctures to determine local stresses, incorporating the effects of thermal stratification. Following the identification of operational loads, the engineers can calculate component stresses and fatigue usage factors to demonstrate compliance with the relevant Code requirements. By utilizing cutting-edge tools and methodologies, BWX Technologies ensures the integrity and safety of nuclear piping systems through meticulous analysis and validation processes.
