Meeting of the Advisory Committee on Reactor Safeguards (ACRS) 
Subcommittee on Structural Analysis

    The ACRS Subcommittee on Structural Analysis will hold a meeting on 
October 3, 2018, at 11545 Rockville Pike, Room T-2B1, Rockville,

    The meeting will be open to public attendance. The agenda for the 
subject meeting shall be as follows:

Wednesday, October 3, 2018--1:00 p.m. Until 4:00 p.m.

    The Subcommittee will review the Nuclear Regulatory Commission 
(NRC) Office of Nuclear Regulatory Research report NUREG/CR-7237, 
``Correlation of Seismic Performance in Similar SSCs (Structures, 
Systems, and

[[Page 49139]]

Components).'' The Subcommittee will hear presentations by and hold 
discussions with the NRC staff and other interested persons regarding 
this matter. The Subcommittee will gather information, analyze relevant 
issues and facts, and formulate proposed positions and actions, as 
appropriate. This briefing is independent of the ACRS Research Quality 
Review.
