## Abstract

The Nuclear Regulatory Commission (NRC) is revising its regulations to add a table that was inadvertently omitted in a correction document published on February 3, 2010 (75 FR 5495). The February 3, 2010 document corrected a final rule published on January 4, 2010 (75 FR 13), that amends the NRC's regulations to provide alternate fracture toughness requirements for protection against pressurized thermal shock (PTS) events for pressurized water reactor (PWR) pressure vessels.
