## II. Discussion

On December 14, 2021, the NRC solicited comments on its draft ISG, “Safety Review of Light-Water Power-Reactor Construction Permit Applications.” The purpose of this ISG is to clarify existing guidance and to assist the NRC staff in determining whether an application to construct a light-water power-reactor facility meets the minimum requirements to issue a construction permit. The public comment period closed on January 28, 2022. The NRC has decided to reopen the public comment period on this document until May 23, 2022 to receive comments on two topics addressed by comments submitted during the initial comment period.

## III. Comments Requested

In considering the comments submitted during the initial comment period, the NRC staff noted two topics that would benefit from additional public feedback and consideration before the ISG is issued final. The NRC staff requests public comments on the following questions:

1. If the NRC were to develop an acceptance review template for light-water power-reactor construction permit applications, what specific information should the template provide that is not currently available in the draft ISG or the NRC's primary review guidance for a construction permit application, NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: [Light-Water Reactor] Edition?”

2. Are there specific review areas where the draft ISG requests a level of detail in the construction permit application that is inconsistent with previous construction permit applications? If so, which specific review areas are involved and how is the level of detail inconsistent with previous construction permit applications?

Comments in response to these questions and on the draft ISG should be submitted in accordance with the instructions described in Section I.B.

Dated: May 2, 2022.

For the Nuclear Regulatory Commission.

Director, Division of New and Renewed Licenses, Office of Nuclear Reactor Regulation.
