US-based small modular reactor developer NuScale expects to receive a standard design approval (SDA) for its 77-MW Voygr module from the US Nuclear Regulatory Commission in 2024, the company’s vice-president of marketing and communications told NucNet.

Diane Hughes said a recent NRC standard design certification for the 50-MW variant of the Voygr module “sets the stage for an efficient and effective review” of the uprated 77-MW design.
