Below is a list of the small modular reactor designers and potential license applicants with whom the NRC is engaged with in pre-application, design certification and standard design approval activities.
Small modular reactor developers interested in beginning preapplication engagement with the NRC staff or planning to submit applications should review "DRAFT Pre-application Engagement to Optimize Advanced Reactors Application Reviews" and respond to RIS-20-02, "Review of New Licensing Applications for Light-Water Reactors and Non-Light Water Reactors," to inform the staff so we can plan our resources accordingly.
