Categories of those changes that should not be deferred include, but are not limited to, the following: a. the correction of significant errors in an application, b. changes needed to ensure compliance with NRC regulations, c. changes needed to support other licensing-basis documents (e.g., conforming changes to information in the FSAR supporting
