Test data from the Marviken containment tests were obtained for the purpose of validating containment pressure codes used for performing independent calculations related to licensing reviews. The Marviken data are containment pressure responses from a full-scale blowdown using a pressure suppression type containment.
This NUREG-0471[1] task would correlate the Marviken data and compare the results with computer programs existed when the issue was identified.
This item is a Licensing Issue. As a part of the improvements to NUREG-0933, the NRC staff clarified in SECY-11-0101, "Summary of Activities Related to Generic Issues Program," dated July 26, 2011,[2] that the
Generic Issues Program will not pursue any further actions toward resolution of licensing and regulatory impact issues. Because licensing and regulatory impact issues are not safety issues by the classification guidance
in the legacy Generic Issues Program, these issues do not meet at least one of the Generic Issues Program screening criteria and do not warrant further processing in accordance with Management Directive 6.4, "Generic
Issues Program," dated November 17, 2009.[3] Therefore, this issue will not be pursued any further in the Generic Issues Program.
