Design, Methods and Validation

The development, design, permitting, and construction of an HTR requires multiple and varied analyses and computational methods. The gas‑cooled thermal reactors built and operated in the United States and elsewhere to‑date are characterized by sustained operations at conditions that have substantial design and safety margins. The margins were designed to be large because the legacy analysis tools were not capable of calculating important local limiting parameters with sufficient accuracy to reduce the safety margins.

The Design Methods and Validation program provides advanced tools for HTGR design and analysis activities. Most of these tools are already available and consist of a mixture of commercial software and software written at the national laboratories. Only limited tool development is necessary for HTR methods. The Design Methods and Validation Control Account consists of two WPs:

  • Experimental Validation

  • Core Simulation.
