Idaho National Laboratory, Advanced Test Reactor Control Room Wall

Scope/Solutions

The Advanced Test Reactor (ATR) at the Idaho National Laboratory (INL) supports research and testing of materials for use in large-scale and prototype reactors. Previous analyses indicated that the eastern partition walls of the control room inside the reactor building have insufficient out-of-plane capacity to resist a design earthquake. SGH evaluated and designed upgrades for the unreinforced concrete masonry partition walls that support numerous equipment and utility lines.

For this project, SGH performed a structural evaluation and designed the upgrades for the masonry partition walls at the east side of the control room for Performance Category 4 (PC-4) compliance. Upgrades include:

  • New vertical and horizontal steel strong backs strategically located to minimize interference with existing equipment and utilities
  • One-sided and through-bolted connections to ungrouted concrete masonry walls
  • Various top and base anchorage details
  • Options for bolted and welded connections to existing structural steel that do not require reinforcement of existing components

We prepared calculations, design drawings, and specifications; and delivered a formal presentation to our client. Our work was independently reviewed and accepted.

Columbia Generating Station, Seismic Probabilistic Risk Assessment

After the Fukushima Daiichi accident, the U.S. Nuclear Regulatory Commission (NRC) issued 10 CFR 50.54(f), a letter requiring licensees to perform a re-evaluation of seismic hazard and take further actions if it exceeds their design basis. In response to this letter, Columbia Generating Station (CGS) performed a seismic probabilistic risk assessment (SPRA) of their facility.
