Conditionally Acceptable Section XI Code Cases The NRC determined that the Code Cases listed in Table 2 are acceptable for application in licensee Section XI ISI programs within the limitations imposed by the NRC staff. Unless otherwise stated, limitations imposed by the NRC are in addition to the conditions specified in the Code Case. ASME published the 2010 Edition of the ASME BPV Code on July 1, 2010. ASME issued an addendum in 2011 but did not issue an addendum in 2012. Beginning in 2013, ASME will issue new editions of the BPV Code every 2 years. ASME will continue to publish Code Cases quarterly in supplements to each edition. To assist users, new and revised Code Cases are shaded to distinguish them from those approved in previous versions of this guide. For Code Cases previously listed in this guide, the third column of Table 1 lists the dates of ASME approvals. For new or revised Code Cases, the third column of Table 1 lists the supplement and edition in which each Code Case was published (e.g., “5/13E” means Supplement 5 to the 2013 Edition of the ASME BPV Code).
