A Glimpse into Advanced Nuclear Reactor Inspections of the Future

Sep 10, 2020

New advanced reactor designs that facilitate an ever-expanding list of applications are coming into play, causing a transition from large nuclear power plants to small modular reactors and even micro nuclear reactors that are mobile. Due to the significant differences between existing reactors and ones that are currently being designed, a new approach was needed for monitoring and inspecting these next-generation nuclear reactors.
ASME developed a new reliability integrity management (RIM) methodology to establish inservice inspection criteria to support these new technologies and address any variables that might challenge safe operations. A recorded webinar on its new BPVC-XI-2-2019 standard is now available on-demand.
The webinar provides the opportunity to explore:
  • BPVC Section XI, Division 2 Reliability Integrity Management
  • What RIM provides and why it is essential to new advanced reactors, small modular reactors and micro reactors
  • Key considerations when designing one of these unique new reactors
  • Reliability target values and other key aspects of this vital new inspection program
BPVC-XI-2 has been in development for over 10 years and is a technology neutral inservice inspection standard that may be applied to all advanced reactor designs, regardless of the technology (e.g., Light Water, Molten Salt, Liquid Metal, etc.) and for any reactor application (e.g., power production, desalination, medical isotope production, etc.).
The overarching foundation for RIM is to (1) identify are risk significant systems, structures and components (SSC) that could affect safe plant operations, (2) identify credible degradation mechanisms that are relevant to these SSC, (3) establish and performance demonstrate monitoring and NDE methods that can credibly be used to detect the onset of any degradation to an SSC, and (4) regularly update the RIM program based on gained operating experience.
