Nuclear Regulatory Commission March 10, 2015 – Federal Register Recent Federal Regulation Documents

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment its Japan Lessons-Learned Division (JLD) draft interim staff guidance (ISG), ``Compliance with Phase 2 of Order EA-13-109, Order Modifying Licenses with Regard to Reliable Hardened Containment Vents Capable of Operation under Severe Accident Conditions,'' (JLD- ISG-2015-01). This draft JLD-ISG would provide guidance and clarification to assist nuclear power reactor licensees identify measures needed to comply with Phase 2 requirements of the ``Order Modifying Licenses with Regard to Reliable Hardened Containment Vents Capable of Operation Under Severe Accident Conditions,'' (Order EA-13- 109) to have either a vent path from the containment drywell or a strategy that makes it unlikely that venting would be needed from the drywell before alternate reliable containment heat removal and pressure control is reestablished.
