Anthony R. Pietrangelo, Nuclear Energy Institute; Consideration of Petition in the Rulemaking Process

摘要

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.
