o defects, design errors, and other early sources of potential failures such as handling and installation errors. The ITP can greatly reduce the possibility of SSCs failing early in plant operation by identifying and correcting these early sources of failures. 4. Procedures The licensee should develop detailed test procedures to implement the ITP, including preoperational, initial criticality, low power and power ascension tests. The SSCs should be tested using procedures that include appropriate checklists and signature blocks to control the sequence and performance of testing. The test procedures should be developed and reviewed by personnel with appropriate technical backgrounds and experience and should receive final approval by persons in designated management positions within the applicant’s or licensee’s organization. In addition, each test procedure should include acceptance criteria that account for the uncertainties used in transient and DG-1259, Page 9 accident analyses. Principal design organizations should participate in establishing those test acceptance criteria and related performance requirements. Test procedures should ensure that temporary instrument cables and test leads used during the startup test phase are routed in a manner that will not compromise electrical separation criteria. Available information on operating experience, including reportable occurrences at operating power reactors, also should be used appropriately in developing and executing the test procedures. Approved test procedures for satisfying FSAR testing commitments should be made available to the NRC approximately 60 days before their intended use. Before fuel loading, the results of completed preoperational tests should be evaluated by personnel or groups that the licensee has designated to determine if any tests and acceptance criteria have not been met. Appropriate remedial actions, including retesting, should be taken if the acceptance criteria associated with
