The purpose of this document is to review the existing the trunnion collar removal machine against the 'Nuclear Safety Design Bases for License Application' (NSDB) requirements and to identify codes and standards and supplemental requirements to meet these requirements. If these codes and standards can not fully meet these requirements then a gap is identified. These gaps will be identified here and addressed using the 'Trunnion Collar Removal Machine Design Development Plan'. The codes and standards, supplemental requirements, and design development requirements for the trunnion collar removal machine are provided in the gap analysis table. Because the trunnion collar removal machine is credited with performing functions important to safety (ITS) in the NSDB, design basis requirements are applicable to ensure equipment is available and performs required safety functions when needed. The gap analysis table is used to identify design objectives and provide a means to satisfy safety requirements.
