SUMMARY: On January 3, 2010, the Nuclear Regulatory Commission (NRC or

Regulations (10 CFR) part 50, section 61a to provide alternate fracture 
toughness requirements for protection against pressurized thermal shock 
(PTS) events for pressurized water reactor (PWR) pressure vessels. On 
February 3, 2010, the NRC published in the Federal Register a 
correction to the final rule (75 FR 5495) to correct formatting and 
typographical errors. This document is necessary to further correct a

applicable beginning February 3, 2010, the date the original rule
