Subject:
Response to email "Hardened vents and filtered vents -- July (2012) report soon?"
Date:
Monday, August 06, 2012 3:24:00 PM Mr. Leyse, Despite Chairman Jaczkos departure, the NRCs actions in response to Japan will continue without delay. With respect to the filtered vents policy paper, the NRC staff has made significant progress on this evaluation and has had frequent engagement with stakeholders (nuclear power industry, public, and nongovernmental organizations). A thorough technical basis is required to support a recommendation to the Commission regarding whether containment vents should be required to operate under severe accident conditions, with or without filters; consequently, additional analysis is required to properly evaluate the potential safety benefit of such requirements. This additional analysis has resulted in an extension request until November 2012 to submit the policy paper.
Columbia Generating Station is subject to NRC order EA-12-50, Issuance of Order to Modify Licenses with Regard to Reliable Hardened Containment Vents, because it is a boiling water reactor with a Mark II containment. Columbia Generating Station is required to install a reliable hardened vent by no later than December 31, 2016.
