2017 UC Pacific Rim Forum:
Earthquake Resilience of Nuclear Facilities

2017 UC Pacific Rim Forum Assembly

On January 23 & 24, 2017, PEER hosted the latest in a series of Pacific Rim Forums focusing on the critical issue of earthquake resilience of nuclear facilities. Nuclear facilities associated with power generation, nuclear materials processing and storage, and nuclear experimental science require the utmost attention with regard to facility resilience and safety.

Around the Pacific Rim, large earthquakes are a major design issue for nuclear facilities and advanced approaches for seismic analysis and design are essential to achieving appropriate levels of risk.

The Pacific Rim Forum on the Earthquake Resilience of Nuclear Facilities is intended to bring together the research and practitioner communities to share recent developments in advancing earthquake hazard and risk assessments, to provide focused discussion on timely challenges facing the nuclear enterprise, and to discuss the societal importance of a breadth of nuclear facilities. The Forum event was hosted in collaboration with the Lawrence Berkeley National Lab, US Department of Energy, American Association of Structural Mechanics in Reactor Technology (AASMiRT), Japan Atomic Industrial Forum (JAIF), and Pacific Gas & Electric Company.

PEER participants joined other invited international experts and leaders from around the Pacific Rim and Europe, from a broad cross-section of academic institutions, national laboratories, commercial sector entities, and governmental agencies.  The topics for the Pacific Rim Forum 2017 are outlined below, with the intent of continuing the excellent dialog and technical exchanges that were generated by the very successful Pacific Rim Forum of 2015.

International perspectives were presented by:

  • Hirobumi Kayama,  Special Advisor to the Ministry of Economy Trade and Industry (METI), Japan
  • Garrett Smith, Acting Director, DOE Office of Nuclear Safety, United States
  • Xin-Zheng Lu for Rong Pan, Director of Plant Siting and Civil Engineering, Nuclear Safety and Radiation Safety Center, China
Panel: S.Mahin, A.Schellenberg, J.Johnson, L.Johnson, I.Buckle

Panel (L to R): S.Mahin, A.Schellenberg, J.Johnson, L.Johnson, I.Buckle, K.Soga
