SUMMARY: The Nuclear Regulatory Commission (NRC) is considering the

``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.

DATES: The docket for the petition for rulemaking PRM-50-75 is closed 
on November 6, 2008.

SUPPLEMENTARY INFORMATION: On April 8, 2002 (67 FR 16654), the NRC 
published for public comment a petition for rulemaking (PRM) filed by 
Anthony R. Pietrangelo, on behalf of the Nuclear Energy Institute. The 
comment period closed on June 24, 2002, and the NRC received eighteen 
comment letters ML082460625. The NRC has determined that the issues 
raised in PRM-50-75 are appropriate for consideration and, in fact, the 
issues are already being considered in the ongoing ``Risk-Informed 
Redefinition of Large Break LOCA ECCS Requirements'' rulemaking. 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.

    Dated at Rockville, Maryland, this 15th day of October 2008.

    For the Nuclear Regulatory Commission.
Bruce S. Mallett,
Acting Executive Director for Operations.
