NRC approves TerraPower construction permit
Today, the Nuclear Regulatory Commission announced that it has approved TerraPower’s construction permit application for Kemmerer Unit 1, the company’s first deployment of Natrium, its flagship sodium fast reactor.
This approval is a significant milestone on three fronts. For TerraPower, it represents another step forward in demonstrating its technology. For the Department of Energy, it reflects progress (despite delays) for the Advanced Reactor Demonstration Program (ARDP). For the NRC, it is the first approval granted to a commercial reactor in nearly a decade—and the first approval of a commercial non–light water reactor in more than 40 years.

This technical note models the concept of fuzziness along with the stochastic behavior of the point-kinetics neutron equation. The fuzzy stochastic model is investigated numerically by extending the Euler-Maruyama method to fuzzy form. The uncertain neutron density and delayed neutron population are obtained and compared with Monte Carlo and stochastic principal component analysis solutions. Various combinations of fuzzy parameters are considered, and the uncertain neutron density and delayed neutron population are obtained in different cases. Finally, the sensitivity of these fuzzy parameters with stochastic behavior is investigated.
