II. Further Information

The NRC seeks public comment on a proposed new section of SRP Section 19.3, “Regulatory Treatment of Non-Safety Systems (RTNSS) for Passive Advanced Light Water Reactors.” This section has been developed to assist NRC staff with the review of applications for certain construction permits, early site permits, licenses, license amendments, and combined licenses and to inform new reactor applicants and other affected entities of proposed SRP guidance regarding an acceptable method by which to evaluate guidance on application review on the subject of loss of large areas of the plant due to explosions and fires. Following NRC staff evaluation of public comments, the NRC intends to incorporate the final approved guidance into the next revision of NUREG-0800.

Dated at Rockville, Maryland, this 4th day of October 2012.
