Resolution and closure of petition docket.
The Nuclear Regulatory Commission (NRC) is considering the issues raised in a petition for rulemaking submitted by Anthony R. Pietrangelo, on behalf of the Nuclear Energy Institute, in the ongoing “Risk-Informed Redefinition of Large Break Loss-of-Coolant Accident (LOCA) Emergency Core Cooling System (ECCS) Requirements” rulemaking. The petitioner requested that the NRC amend its regulations to allow the use of an alternative to the currently required double-ended rupture of the largest pipe in the reactor coolant system in ECCS evaluation models.
The docket for the petition for rulemaking PRM-50-75 is closed on November 6, 2008.

This proposed rule was published on April 8, 2005 (67 FR 16654), and a report on “Seismic Considerations for the Transition Break Size” was published for public comment on December 20, 2005 (70 FR 75501). The comment periods for both the proposed rule and the report expired on February 6, 2006. The NRC will address substantive comments filed in PRM-50-75 as part of the “Risk-Informed Redefinition of Large Break LOCA ECCS Requirements” rulemaking.Start Signature
