View Rule

When compared to potential accidents at an operating reactor, the risk of an offsite radiological release is significantly lower, and the types of possible accidents are significantly fewer, at a nuclear power reactor that has permanently ceased operations and removed fuel from the reactor vessel than at an operating reactor. These shutdown reactors remain subject to many of the same requirements as operating reactors.  Because the development of regulations for operating nuclear power plants often did not consider decommissioning, the requirements imposed on decommissioning nuclear power reactors may be inappropriate, may not be applicable, or may not align with safety significance. In SRM-SECY-14-0118, the Commission directed the staff to proceed with rulemaking on decommissioning and set an objective of early 2019 for completion of this rulemaking.  The Commission also stated that this rulemaking should address:  issues discussed in SECY-00-0145, such as the graded approach to emergency preparedness; lessons learned from the plants that have already (or are currently) going through the decommissioning process; the advisability of requiring a licensee’s Post-Shutdown Decommissioning Activity Report to be approved by the Nuclear Regulatory Commission; the appropriateness of maintaining the three existing options for decommissioning and the timeframes associated with those options; the appropriate role of State and local governments and non-governmental stakeholders in the decommissioning process; and any other issues deemed relevant by the Nuclear Regulatory Commission staff.
